Abstract:
Background: A quantitative myocardial perfusion imaging (MPI) and oncologic - including molecular breast imaging (MBI) - utility patent (FMTVDM*) previously validated at experienced MPI and MBI centers was independently tested for clinical application at a private practice Reno, Nevada cardiologists office. Methods: Using FMTVDM, a private practice cardiologist independently investigated forty-four regions of interest (ROI) in 12-women with varying transitional levels of breast changes – including breast cancer. Results: Using FMTVDM, a nuclear cardiologist without prior experience in MBI was able to easily measure changes in women’s breast tissue differentiating inflammatory and cancerous breast tissue from normal using the same camera used for MPI. These measured changes provided diagnostically useful information on cellular metabolism and regional blood flow changes (RBF) – the same properties which differentiate ischemic coronary artery disease (CAD) on myocardial perfusion imaging (MPI). Conclusions: Quantitative MBI using FMTVDM allows differentiation of tissue types through measurement of enhanced regional blood flow and metabolic differences. Nuclear cardiologists have previously reported cases of breast cancer while conducting MPI studies. This investigation demonstrated that nuclear cardiologists can independently conduct MBI in addition to MPI studies using the nuclear cameras they currently use for MPI.

Abstract:
Elevated cardiac troponin (cTn) showed associations with mortality even in stable patients, but management has not been established. We aimed to investigate whether consultation to cardiologists could reduce mortality of stable patients with cTn elevation at admission. We identified 1329 patients with elevated cTn level at hospitalization from outpatient clinic to any department other than cardiology or cardiac surgery between April 2010 and December 2018. The patients were divided into two groups according to cardiologist consultation at admission. For primary outcome, mortality during one year was compared in the crude and propensity-score-matched populations. In 1329 patients, 397 (29.9%) were consulted to cardiologists and 932 (70.1%) were not. Mortality during the first year was significantly lower in patients consulted to cardiologists compared with those who were not (9.8% vs. 14.2%; hazard ratio (HR), 0.50; 95% confidence interval (CI), 0.35–0.72; p < 0.001). After propensity-score matching, 324 patients were in the cardiologist consultation group and 560 patients were in the no cardiologist consultation group. One-year mortality was consistently lower in the cardiologist consultation group (10.5% vs. 14.6%; HR, 0.58; 95% CI, 0.39–0.86; p = 0.01). Cardiologist consultation may be associated with lower mortality in stable patients with cTn elevation at admission. Further studies are needed to identify effective management strategies for stable patients with elevated cTn.

Abstract:
PurposeImplantable cardioverter defibrillator (ICD) implantation rates remain variable despite established guideline recommendations. This study aims to assess whether being managed by a cardiologist has an impact on whether patients are considered for an ICD for primary prevention of sudden cardiac death.Design/MethodsSingle-centre, retrospective, observational study of patients identified to have severe left ventricular systolic dysfunction (LVSD) on echocardiography (n = 129) between 1 and 30 June 2016 with cross-sectional assessment at 1 year. An assessment of ICD consideration at 1 year following the echocardiogram was documented, in addition to the specialty of the managing physician (group 1—electrophysiologist/heart failure specialist; group 2—all other cardiologists; group 3—non-cardiologist).Results129/1173 (11%) transthoracic echocardiographies (s) were identified to have severe LVSD. 52 (40%), 37 (29%) and 40 (31%) were managed by group 1, group 2 and group 3, respectively. Mean age was 74.7 (±12.6) years with a predominance of male gender (70.5%). An ICD was not considered in 47.3%. Those managed by a cardiologist were more likely to be considered for an ICD than a non-cardiologist (63.9% vs 30.0%; OR 4.0, 95% CI 1.8 to 8.8, p = 0.001) with a greater survival at 1 year (89.9% vs 52.5%, OR 8.1 95% CI 3.2 to 20.4, p < 0.001). Group 1 were more likely to consider ICD than group 2 cardiologists (75.0% vs 45.9%; OR 3.5; 95% CI 1.4 to 8.7, p = 0.005).ConclusionThere is significant variation between cardiologists and non-cardiologists, as well as within different cardiology subspecialists, when considering the option of ICD therapy for primary prevention.

Abstract:
To identify the important tradeoffs in consulting a single expert for both diagnosis and treatment, we examine the costs and health outcomes of elderly Medicare beneficiaries with coronary artery disease. We compare the empirical consequences of diagnosis by cardiologists who can provide surgical treatment – “integrated” cardiologists – to the consequences of diagnosis by a nonintegrated cardiologist. Diagnosis by an integrated cardiologist leads, on net, to higher health spending but similar health outcomes. The net effect contains three components: reduced spending and improved outcomes from better allocation of patients to surgical treatment options; increased spending conditional on treatment option; and worse outcomes from poorer provision of nonsurgical care.

Abstract:
Da tempo ormai stiamo sostenendo che Cardiologia Ambulatoriale e Cardiologia Territoriale non sono termini fra loro indipendenti né, tanto meno, antitetici, bensì in larga misura sinonimi della stessa disciplina. La cardiologia del territorio è semplicemente una articolazione della più generale cardiologia ambulatoriale. L’ambulatorio cardiologico ha infatti la stessa struttura, lo stesso ruolo e le stesse finalità sia se ubicato in un ospedale, sia se ubicato sul territorio, cioè in una sede extraospedaliera. Non è dunque un caso che A.R.C.A. abbia preferito definirsi fin dalla sua fondazione l’associazione dei cardiologi ambulatoriali e non l’associazione dei cardiologi extraospedalieri o l’associazione dei cardiologi del territorio. Cardiologia ambulatoriale ha connotazioni molto più ampie rispetto agli altri due termini. Nell’ambulatorio cardiologico, indifferentemente se collocato in ospedale o fuori dall’ospedale, la disciplina specialistica cardiologica è articolata in una serie di attività importanti e differenziate fra loro: – gestione del profilo di rischio individuale, identificazione e trattamento dei fattori di rischio, counseling sugli stili di vita: in altre parole prevenzione primaria delle malattie cardiovascolari; – prevenzione secondaria e terziaria delle malattie cardiovascolari; – valutazione e presa in carico dei pazienti con sintomi indicativi di sospetta cardiopatia (dolore toracico, dispnea, cardiopalmo, sincope, ecc.). – gestione diagnostica, terapeutica e stratificazione del rischio di questi pazienti per l’avvio ad eventuali ulteriori processi di cura; – follow-up a lungo termine dopo la fase acuta di una cardiopatia; – follow-up di patologie tipicamente croniche come l’ipertensione arteriosa e lo scompenso cardiaco.

Abstract:
<p>Interventional procedures, cine acquisitions and operation of fluoroscopic equipment in high-dose fluoroscopic modes, involve long fluoroscopic times which can lead to high staff doses. Also, Coronary angiography (CA) procedures require the cardiologist and assisting personnel to remain close to the patient, which is the main source of scattered radiation. Thus, radiation exposure is a significant concern for radiation workers and it is important to measure the radiation doses received by personnel and evaluate the parameters concerning total radiation burden. In this research, we investigated radiation doses to 10 cardiologists performing 120 CA procedures. Using thermo luminescent dosimeters doses to the wrists, thyroid and eyes per procedure were measured. Based on the measured dose values, maximum doses to the Left wrist, Right wrist, thyroid and eyes of cardiologist were measured 241.45 µSv, 203.17 µSv, 78.21 µSv and 44.58 µSv, respectively. The results of this study indicate that distance from the source, use of protective equipment's, procedure complexity, equipment performance, and cardiologist experience are the principal exposure-determining variables. It can be conclude that if adequate radiation protection approaches have been implemented, occupational dose levels to cardiologists would be within the regulated acceptable dose limits.</p>

Abstract:
Aim. To assess the quality of diagnostics and treatment of outpatients with a history of myocardial infarction (MI) according to REGATA register.Material and methods. In 2012-2013, 481 patients with a MI history who sought help in ambulatory care clinic were included in the study. In 87,5% of cases, the reference visit was to a physician or cardiologist, in 12,5% — to other specialist. The median age was 72 [62; 78] years (men — 51,4% (n=247)). The median time of previous MI was 5 [2; 9] years before the inclusion date.Results. A total of 23,5% of patients with previous MI had never visited a cardiologist before, 37% of patients visited a cardiologist in the last 12 months before being included in the registry. The use of diagnostic tests was insufficient, regardless of specialty of a doctor managing a patient. In patients managed by a cardiologist, electrocardiography, 24-hour Holter ECG monitoring, echocardiography, exercise tolerance test were much more often used. Cardiovascular agents were prescribed at the last visit to a physician and/or cardiologist in 91,9% of cases. Angiotensin converting enzyme inhibitors were used in 49,6% of patients, sartan medicines — 25,6%, beta-blockers — 57,7%, calcium channel antagonists — 21,7%, long-acting nitrates — 20,0%, statins — 45,1 %, antiplatelet agents — 67,3%. In patients who visited/not visited a cardiologist, the frequency of prescribing cardiovascular agents did not significantly differ, except for statins (50,0% vs 23,9%, respectively (p<0,0001)).Conclusion. The results obtained indicate that quality of managing outpatients after MI is higher by cardiologists than by physicians. However, the use of diagnostic tests and cardiovascular agents is insufficient, regardless of specialty of a doctor managing a patient.

Abstract:
Introduction: Congenital Heart Diseases are the commonest birth defects and the most common reason for out-country referral of pediatric patients in Bhutan.Without any qualified pediatric cardiologists in the country, early diagnosis and appropriate care of pediatric cardiac patients is often delayed or inappropriate. Collaboration through telemedicine between general pediatrician and pediatric cardiologist can improve the diagnosis of congenital heart diseases in Bhutan.
 Methods: Pediatric patients clinically suspected to have congenital heart diseases underwent Echocardiography at Mongar regional referral hospital. The Echocardiograms, performed by general pediatrician, were e-mailed to Pediatric Cardiologist working in UK, who gave the diagnosis after viewing the Echo-loops. This was compared with the final diagnosis made at tertiary cardiac centre in India.
 Results: 30 echocardiograms performed by general pediatrician at Mongar Hospital in eastern Bhutan were mailed to Pediatric Cardiologist working in UK. Of the thirty cases, 20 required no immediate referral and were put on medications and follow up plans. 10 of the 30 cases requiredearly referral to tertiary care hospital in India. There was excellent concordance between the diagnosis made through tele-echocardiology and the final diagnosis made at tertiary cardiac centre.
 Conclusions: Tele-echocardiography between a general Pediatrician and a Pediatric Cardiologist can greatly enhance the diagnosis of congenital heart diseases in children.

Abstract:
We assessed prospectively the prevalence 01 pathologic and Innocent murmurs in childhood, to determine the efficacy of clinical evaluation, to compare the results of physical examinations performed by pediatricians and pediatric cardiologists and echocardiographic evaluations, and to contribute to the determination of the limits of echocardiography indications in children with murmurs. A number of 8647 children, aged 6.5-15 years, 4092 females, 4455 males in ten different primary schools belonging to different socioeconomic levels in Malatya, Eastern Turkey. Those children with a murmur were evaluated by a pediatric cardiologist. Chest X-ray, electrocardiography, and echocardlography were obtained in all subjects having a murmur. The results of physical examinations performed by the pediatricians and the pediatric cardiologist were compared, and the final diagnoses were reached by evaluation of chest X-ray, ECG and chocardiography. The incidence of Innocent murmurs was found to be 3.4% and that of pathological murmurs 0.54% In the population eximaned. The statistical comparison of the results revealed that pediatricians have a tendency toward Innocent murmurs in the interpretation of murmurs (p<0.05). There was not a statistically significant difference between the results of physical examinations of the pediatric cardiologist and the results of echocardlographic examination. Pediatricians can diagnose pathologic cases with a sensitivity of 63.8% whereas pediatric cardiologist could diagnose those cases with a sensitivity of 95.7% and specificity of 99.7%. Our findings support the policy that children with a cardiac murmur should be referred to a pediatric cardiologist, in order to verify clinical diagnosis.

Abstract:
Le vieillissement vasculaire est un phénomène inéluctable. Il s'accompagne de modifications structurelles et fonctionnelles du système cardio-vasculaire constituant la rigidité vasculaire. Ce processus dégénératif affecte essentiellement la matrice extra cellulaire des artères élastiques. La perte de l'élasticité du système vasculaire va impacter la fonction ventriculaire gauche et la perfusion cardiaque, rénale et cérébrale par des mécanismes différents. La rigidité vasculaire est un puissant marqueur de risque cardio-vasculaire. Cette notion est peu répandue dans le domaine de la cardiologie interventionnelle alors qu'elle pourrait avoir des implications pronostiques et thérapeutiques importantes. Nous nous sommes intéressés à deux domaines de la cardiologie interventionnelle, pour lesquels la rigidité vasculaire pourrait ouvrir de nouvelles voies de recherche, la maladie coronaire et le traitement interventionnel du rétrécissement aortique. Concernant la maladie coronaire il existe un besoin de mieux comprendre la physiopathologie de la microcirculation et de l'ischémie myocardique. La survenue des accidents coronaires aigus reste également incomplètement comprise. Nous avons abordé la problématique par une approche épidémiologique en étudiant l'impact pronostique de la rigidité vasculaire sur la mortalité liée aux coronaropathies dans une cohorte de 1034 patients hypertendus avec 30 années de suivi. La rigidité vasculaire a été appréciée par la pression pulsée et un score d'athérosclérose de l'aorte abdominale. Un lien très fort a été mis en évidence entre la rigidité vasculaire et la survenue d'infarctus du myocarde. Nous avons ensuite développé un moyen d'étudier la rigidité vasculaire localement au niveau des artères coronaires. Nous avons mis au point une technique de mesure de la vitesse de l'onde de pouls coronaire. Cette technique repose sur l'utilisation d'un guide de pression ntra-coronaire et un algorithme breveté du traitement de signal. Nous sommes parvenus à mesurer une vitesse de l'onde de pouls sur 71 artères coronaires chez 49 patients. Nous avons observé une vitesse de l'onde de pouls plus lente témoignant d'artères plus compliantes chez les patients présentant un infarctus du myocarde en comparaison aux patients présentant un angor stable. Nous avons également constaté une augmentation de la vitesse de l'onde de pouls après implantation d'un stent endocoronaire témoignant d'une rigidification attendue de l'artère coronaire. Ces travaux pourraient ouvrir une nouvelle voie de recherche dans la compréhension de l'ischémie myocardique et de la survenue de l'accident coronaire aigu à savoir l'interaction rigidité vasculaire globale et rigidité locale coronaire. Concernant le traitement interventionnel du rétrécissement aortique, de nouveaux facteurs prédictifs du bénéfice de l'intervention sont nécessaires chez des patients souvent âgés et fragiles. Nous nous sommes intéressés à l'étude du volume de calcifications de l'aorte, reflet de la rigidité vasculaire. Ce paramètre a été mesuré par scanner chez des patients traités par remplacement valvulaire aortique par voie percutanée appelé TAVI pour transcatheter aortic valve implantation. Nous avons d'abord montré que le volume de calcifications de l'aorte ascendante était un puissant marqueur de risque indépendant de mortalité cardiaque et d'insuffisance cardiaque sur une série de 127 patients consécutifs traités par TAVI, avec un suivi médian de 907 jours. Ce travail a ensuite été complété en étudiant le volume de calcifications de l'aorte totale sur une série de 164 patients. Le volume de calcifications de l'aorte complète était prédicteur de mortalité totale et cardiaque. De plus, chaque segment d'aorte pris séparément (aorte ascendante, descendante et abdominale) prédisait la mortalité cardiaque. Enfin, seul le volume de calcifications du segment ascendant était prédicteur d'insuffisance cardiaque [etc…]<br>Vascular aging is an inevitable phenomenon. It is accompanied by structural and functional modifications of the cardiovascular system mainly referred to as vascular stiffening. This degenerative process essentially affects the extracellular matrix of the elastic arteries. The loss of elasticity of the vascular tree affects left ventricular function as well as cardiac, renal and cerebral perfusions involving different mechanisms. Vascular stiffness is a powerful risk marker of cardiovascular disease. However, most interventional cardiologists are not familiar with this concept while it may have both important prognostic and therapeutic implications. We tackled two areas of interventional cardiology, where vascular stiffness may open new fields of research; coronary artery disease and interventional treatment of aortic stenosis namely, transcatheter aortic valve implantation (TAVI). With regards to coronary artery disease there is a need to better understand the pathophysiology of microcirculation and myocardial ischemia. Moreover, the occurrence of acute coronary events is also incompletely understood. Our first approach was epidemiological. We studied the prognostic impact of vascular stiffness on coronary artery disease mortality in a cohort of 1034 hypertensive patients after 30 years of follow-up. Vascular stiffness was assessed both by pulse pressure and by a score related to atherosclerosis of the abdominal aorta. A strong link was found between vascular stiffness and the occurrence of myocardial infarction and coronary artery disease related deaths. We then developed a way to study the local vascular stiffness at coronary artery level by measuring coronary pulse wave velocity. This technique relies on the use of an intracoronary pressure wire and a patented signal processing algorithm. We measured a coronary pulse wave velocity on 71 coronary arteries in 49 patients. Interestingly, patients with acute coronary syndromes had a lower coronary pulse wave velocity (which means more compliant arteries) when compared to patients with stable coronary artery disease. After an endocoronary stent implantation we noticed an increase of coronary pulse wave velocity in line with an expected stiffening. This work opens a new avenue of research regarding coronary perfusion physiology and plaque complications by studying the interaction of regional vascular stiffness and local coronary stiffness. Regarding TAVI, a procedure that often concerns elderly and frail patients, new factors predicting the benefit of the intervention are needed. We studied aortic calcifications as a surrogate of vascular stiffness. This parameter was measured by CT scan before TAVI. We first showed in 127 consecutive patients with a median follow-up of 907 days that ascending aorta calcifications were a powerful risk marker of cardiac mortality and heart failure after TAVI. This study was then completed by studying the volume of the whole aorta in 164 patients. The volume of calcifications of the whole aorta was a predictor of both all-cause and cardiac mortality. In addition, each segment of aorta taken separately (ascending, descending and abdominal aorta) predicted cardiac mortality. Finally, only ascending aorta calcifications predicted heart failure. These results support the hypothesis that ascending aorta calcifications are a marker of vascular stiffness and contribute to the left ventricular afterload. Moreover the volume of the whole aorta could mirror the global atherosclerosis burden of the patient. This easily measurable parameter could thus represent a new risk stratification tool in patients treated with TAVI. This work on vascular stiffness opens a new field of research in several areas of interventional cardiology. Regarding coronary artery disease, coronary pulse wave velocity could represent a way to better understand coronary perfusion, microcirculation, ischemia and the occurrence of coronary plaque rupture [etc...]

Abstract:
Mestrado em Engenharia de Computadores e Telemática<br>A sociedade á marcada por uma evolução constante e contínua a todos os níveis: sociais, políticos, económicos e até dos próprios conceitos da medicina e os princípios axiológicos em que estes se fundamentam. A par e passo, a ciência, enquanto conhecimento estruturado e prático, necessita ser repensada, acompanhando os moldes evolutivos da sociedade em que se insere. Mas, infelizmente, não são só a sociedade e a ciência a sofrer transformações. Ao nível da medicina constata-se que as doenças poderão classificar-se como cada vez mais severas e mais complexas, daí derivando a necessidade urgente de descobrir/reestruturar novas práticas e recursos que as minimizem, uma vez que as soluções de ontem não são aplicáveis ás realidades do hoje, logo, muito menos são solução para os problemas de amanhã. Comprova-se, deste modo, a necessidade subjacente de documentar as novas descobertas e/ou as alterações que se vão verificando ao longo do tempo, tanto nos tratamentos como nas próprias doenças. Urge documentar e preservar todos os parâmetros de informação atrás enumerados. Estes processos de catalogação da informação, além de morosos, provocam um crescendo contínuo, acumulando informação em cima de informação, tornando-a quase ilegível e intratável do ponto de vista do investigador. Isto porque, todo o investigador pretende rentabilizar o seu tempo não o gastando com burocracias mas investindo-o na pesquisa de alternativas para a cura/tratamento das maleitas supervenientes. Ora, há necessidade de a armazenar de forma adequada e organizada. O caso específico da cardiologia, no âmbito da pesquisa e catalogação de novas informações e conceitos, não e exceção, pois revela carências ao nível do aperfeiçoamento na organização dos dados recolhidos. Assim, o objetivo e a implementação de um sistema que permita armazenar casos e fazer todas as tarefas que este permite, tendo sempre em conta um baixo custo, simplicidade, consistência e futuras evoluções. Neste trabalho pretende-se estudar a estrutura dos casos clínicos enquanto peças documentais que pelo seu conteúdo se revestem de interesse formativo, técnico e científico na área da medicina, nomeadamente, em cardiologia. Um caso clínico toma forma como meio de divulgação e resultado da atividade médica assistida, quando registado em diversos suportes, sejam eles em papel, digitais (mais comummente utilizados na atualidade) ou outros. As modernas tecnologias de publicação Web proporcionam meios inovadores de apresentar os casos clínicos. Impõe-se desenvolver uma plataforma de gestão de todo o processo de publicação desde a submissão, edição, revisão e publicação propriamente dita de um caso clínico. O modelo de dados e aglutinador e abrangente: abarca toda a informação relativa ao paciente bem como todos os atores que nele participaram. Recorreu-se a SQL Server, ASP.net e HTML como principais linguagens de programação utilizadas na execução desta plataforma. Esta, pelas suas características, transcende o contexto de mero repositório pelo facto de permitir a partilha de informação e incluir um subsistema de textitrating.<br>Society is de ned by a constant and continuous evolution in many levels: social, political, economical and even the theory of medicine itself. Science, as a structured and practical source of knowledge, needs to be thought over, step-by-step, keeping in mind the normal ow of social evolution, and medical sciences are no exception. In medical sciences its noticed that diseases can be classi ed increasingly more severe and complex, hence the urgent need to discover/restructure new practices and resources that minimize them, since the solutions from yesterday may not solve today's problems. This way it can be veri ed the subjacent need to document the new discoveries and/or the changes in treatments and diseases that occur from time to time. It is absolutely necessary to document and preserve all the topics of information above enumerated. The processes of cataloguing information, beyond time consuming, imposes an increasing growth of stacked information, that in time becomes nearly unreadable and di cult to handle for research purposes. This because every researcher would rather spend their time researching for alternative cures/treatments for arising diseases, than spending it in legal formalities. There is however the need to store and organize all that information properly. In what concerns the research and cataloguing of new data for the cardiology services, there is the need to improve its structural organization of collected information. Therefore, the goal is to create and implement a platform that enables users to store clinical records and perform all the necessary tasks, keeping in mind reduced costs, simplicity, consistency and future implementations. In this work it is intended the study and structuration of clinical records as documents that through its content become important academic, technical and scienti c medical resources, namely for cardiology. A clinical record takes shape as a way of sharing the results of assisted medical activity, when registered in several platforms, those being on paper, digital (more commonly used nowadays) or others. Modern web publishing technologies provide innovative means of presenting clinical records. Imposing the development of a management platform to overview all the publishing, submission, edition and revision procedures. The data model is cohesive and embracing: including all the information relative to the patient and all the intervening subjects. In the implementation of this platform the main programming languages used were: SQL Server, ASP.net and HTML. Which because of its characteristics transcends the context of mere repository, by the fact that it shares information and includes a rating subsystem.

É onde entra a Mineração de Dados, que tem sido, nos últimos anos, fator contribuinte na criação de ferramentas médicas que têm causado um forte impacto na prestação dos serviços de saúde. Nesse contexto, a proposta deste trabalho é avaliar a Mineração de Dados como meio para conceber um Sistema de Apoio à Decisão que auxilie o processo decisório na Medicina, especificamente na Cardiologia Infantil. Foram utilizadas técnicas de Inteligência Artificial tradicionalmente aplicadas a uma variedade de domínios médicos: Árvores de Decisão e Regras de Classificação, para descrição dos dados; e Redes Neurais Artificiais, para construção de classificadores. O resultado obtido a partir das primeiras técnicas trouxe novos conhecimentos para os médicos envolvidos, especialistas no domínio. Os classificadores criados, por sua vez, mostraram um desempenho satisfatório em duas tarefas distintas: a primeira é classificar os pacientes como saudáveis ou doentes em relação a doenças cardíacas, através de dados de exames de ecocardiogramas; a segunda, identificar, entre os novos pacientes da clínica, e sem a ajuda dos dados de exames clínicos, aqueles mais graves, com alto potencial de serem submetidos a alguma cirurgia cardíaca. A qualidade da solução desenvolvida e a sua aceitação pelos especialistas no domínio mostraram a viabilidade em utilizar a Mineração de Dados no processo de apoio à decisão na Cardiologia Infantil. Entre os potenciais benefícios, estão o maior entendimento da saúde cardíaca da população, e a utilização dos classificadores construídos, para servir como uma segunda opinião médica no momento do diagnóstico e para dar prioridade de atendimento aos pacientes mais graves. Esperase que, com o auxílio dessas ferramentas, haja uma melhoria do serviço médico prestado

Abstract:
Patients with impaired left ventricular systolic function have an increased risk of sudden cardiac death. The implantable cardioverter defibrillator (ICD) is an effective therapy to treat life-threatening arrhythmias and randomized controlled trials have demonstrated statistically significant reductions in all-cause mortality in select patient groups. Despite this wealth of published data, the uptake of ICDs in high risk population remains low and the exact reasons not known. My study focuses on the evidence for ICD therapy from the landmark RCTs that have influenced the current guidelines. Most trials have only published relative risk reduction or hazard ratios. The first part of this thesis analyzes data to reveal absolute risk reduction, the number needed to treat and the findings standardized for length of follow-up. There is considerable variation in the magnitude of benefit between different heart failure aetiologies and other patient characteristics highlighting the difficulty in generalising the results. UK cardiologists’ knowledge of guidelines, estimates of 3-year mortality, management decisions, factors that influence decisions, influence of age, device cost, and overall attitudes to ICDs as a form of therapy was assessed with a questionnaire. There was lack of awareness of UK ICD guidelines amongst non-implanting cardiologists and even when guidelines were known they were often not applied, particularly in primary prevention setting. Most cardiologists are not aware of the magnitude of benefit an ICD offers and overestimate the effect in secondary prevention. In addition, there is also bias against elderly patients. The final part of my thesis focuses on exploring barriers to primary prevention ICD uptake. The aim was to see what action was taken when all the data required for making a referral or assessment was available. Our study suggests more than half of potentially eligible patients do not receive ICD therapy. A low referral rate, lack of screening programmes and age bias seem to be the stumbling blocks for primary prevention ICD in the UK.

Abstract:
Les cardiopathies congénitales (CC) représentent la première cause d’anomalie malformative à la naissance. Les progrès considérables des années 80 (CEC néonatale, diagnostic prénatal) en ont modifié l’épidémiologie, avec un transfert de la mortalité de la pédiatrie à l’âge adulte. Dans ce contexte, l’évaluation de la qualité de vie liée à la santé (QdV) des enfants et adultes porteurs de CC devient un critère de jugement important, en recherche clinique comme dans les soins. Nous avons mené 4 études prospectives de QdV chez des patients avec CC: une étude chez 282 enfants de 8 à 18 ans avec CC comparés à 180 enfants contrôles; une étude sur 202 enfants avec CC corrélant QdV et VO2; une étude de QdV sur 208 adolescents et adultes porteurs d'HTAP sur CC; et une étude sur l’évolution de la QdV de 111 enfants sous AVK participant à un programme d’éducation thérapeutique. Les patients avec CC simple ont manifesté une QdV similaire à celle de la population générale. Ceux avec une cardiopathie complexe ont été préférentiellement impactés sur leur bien-être physique mais ont développé aussi des mécanismes de coping. En pédiatrie, l’évaluation de la QdV par les parents était plus péjorative mais parfois plus pertinente que celle des enfants. Nous avons mis en évidence le lien entre QdV et VO2 chez l’enfant cardiaque. Les résultats de nos travaux devraient permettre d’aider les cardiologues, cardiopédiatres et chirurgiens cardiaques dans leurs annonces diagnostiques, en particulier lors des moments cruciaux de notre sur-spécialité médico-chirurgicale: diagnostic prénatal, réanimation, transition vers l’âge adulte, prise en charge palliative d’une cardiopathie sévère<br>Congenital heart diseases (CHD) are the leading cause of birth malformations. The tremendous progress since the 80’s (neonatal bypass, prenatal diagnosis) have changed the epidemiology, transferring mortality from pediatrics to adulthood. Therefore assessing the health-related quality of life (QoL) of children and adults suffering from CHD has become an important issue, in both clinical research and patients’ follow-up. We carried out 4 prospective QoL studies in patients with CHD: a study in 282 CHD children aged 8 to 18 compared with 180 controls; a study among 202 CHD children correlating their QoL scores to VO2; a QoL study among 208 adolescents and adults with PAH-CHD; and a study among 111 children in a therapeutic anticoagulation education program aiming to measure the evolution of their QoL. Patients with simple CHD showed a similar QoL to that of the control population. Those with complex heart diseases were preferentially affected in their physical well-being but also developed mechanisms of coping in other dimensions. In pediatrics, the evaluation of the QoL by parents is essential, sometimes more accurate than that of children themselves. As in previous studies in adults with heart failure, we found a significant relationship between QoL and physical performance during exercise in CHD children. The results of our work should help cardiologists, cardiac surgeons and pediatric cardiologists in their diagnostic announcement, especially during crucial moments of this medical and surgical subspecialty: prenatal diagnosis, intensive care, transition of care from adolescence to adulthood, palliative treatment of a complex CHD

Abstract:
Primary care physicians (PCPs) often lack the skills to distinguish the common innocent Still’s murmur from far less frequent but potentially serious pathological heart murmurs. This leads to approximately 800,000 children being referred to pediatric cardiologists each year for evaluation of heart murmurs in the United States [1–2]. The murmur is ultimately diagnosed as an innocent Still’s murmur in approximately 78% of these children (Children’s National Health System data). These unnecessary referrals and associated tests cost the healthcare system over half a billion annually, and are a source of avoidable anxiety for children and families while waiting to see a pediatric cardiologist.

Abstract:
In 1975 the valencian cardiologist F. Torrent-Guasp described the heart as a Helical Ventricular Myocardial Band (HVMB) in which “The ventricular myocardium is presented when it is unrolled under the form of a single big muscular band that, due to its special disposition, describes two cavities in the intact heart” [1]. It gives a different perspective of the morphology of the heart than the current and it could explain better and most coherently the propagation of the electrical stimulus which activates the shortening of the fibres, the complex deformation movement of the heart and maybe an explanation about understanding the cardiac contraction.

Abstract:
Accurate assessment of diastolic (dys)function by non-invasive techniques has important therapeutic and prognostic implications but remains a challenge to the cardiologist. A promising parameter to evaluate diastolic (dys)function more accurately is the early diastolic intraventricular pressure gradient (IVPGe) which is considered representative of the active relaxation of the left ventricle. It has been shown that IVPGe can be estimated non-invasively by measuring blood velocities along a base-to-apex scan line using color M-mode Doppler (CMD) echography [1]. Although this technique is known for about 20 years, IVPGe is still not used in daily clinical practice because its approach is complicated and too laborious [2].
