Full textCardiovascular diseases are the leading cause of death among patients with impaired lung function. It is known that pulmonary hypertension and right heart failure are often companion of severe chronic obstructive pulmonary disease (COPD). Left ventricular dysfunction is still not well studied and it is the subject of numerous studies in patients with COPD in recent years. The aim of this dissertation is to examine the function of left ventricle and the presence of pulmonary hypertension in patients with COPD. Materials and Methods: The study included 120 patients who meet the GOLD criteria for COPD. They were divided into four groups of 30 patients for each of the four stages of the disease. All patients underwent echocardiography and spiropletismography. Results: Analysis of the obtained values of the systolic function parameters (stroke volume (SV) and it’s index (SVI), ejection fraction (EF), fractional shortening) show impaired systolic left ventricular function in patients with COPD. With disease progression SV and SVI decrease. With increased severity of COPD the values of ejection fraction decreases. We showed diastolic dysfunction of the left ventricle in COPD patients. Transmitral continuous flow Doppler and tissue Doppler recorded reduced values of the mean E / A and E '/ A' in all stages of the disease. Examining the presence of pulmonary hypertension, we have shown that the systolic pressure in the right ventricle (RVSP) was the lowest in the early stages of COPD, gradually increases with the severity of disease and the highest value was recorded in the fourth stage of the disease. The high prevalence of functional changes in the heart that we have proved in our research highlights the need for echocardiography in the detection of these disorders in COPD.

Full textObjective: The aim of this study is to determine the predictive value of individual and combined echocardiographic parameters of the right ventricle for the occurrence of major adverse cardiac events in patients with chronic heart failure with reduced ejection fraction, during one-year follow-up. Methodology: The study included 191 patients, hospitalized with symptoms and signs of heart failure with reduced ejection fraction, from June 2016 to March 2017. All patients were subjected to clinical examination, laboratory analysis and transthoracic echocardiography. Patients were then followed up for one year in order to detect major adverse cardiac events (cardiac deaths, deaths due to other non-cardiac causes, rehospitalisation due to acute chronic heart failure, cardiac infarction, malignant ventricular disorders of rhythm and stroke). During a mean follow-up of 340±84 days, 111 patients reached the primary endpoint. Results and discussion: The following echo parameters of the right ventricle were selected as the important predictors of adverse cardiac events. Morphological parameter - RV1 (cut off threshold was 42 mm ); systolic function parameter - TAs (cut off value was 10 cm / s); right ventricular load parameter - RVSP (cut off value 40 mmHg) and combined parameters - TAs / RVSP (cut off value was 1.92 cm / s / mmHg) and TAPSE / RVSP (cut off value was 0.28 mm / mmHg). Combined echocardiographic parameters, which represent a combination of different properties of the right chamber, have a greater predictive significance than individual parameters. TAPSE / RVSP stands out among them (parameters of systolic function and right chamber load). Among all the observed demographic, clinical, laboratory and echocardiographic parameters of both chambers, the parameter TAPSE / RVSP <0.28 mm / mmHg is again stands out to a statistically significant and independent predictor of an adverse outcome. The combined parameters: TAs'/RVSP and TAs'x PVAcT (parameters of systolic function and right chamber load) were not described in the literature, so far. They were significantly related to the occurrence of an adverse cardiac outcome in my research. In the final multivariate analysis (among the demographic, clinical, laboratory and echocardiographic parameters of both chambers), five parameters were statistically significant independent predictors of an unwanted output: age; atrial fibrilation; swollen veins; pretibial edema and TAPSE / RVSP. A logistic model, for estimating the likelihood of the occurrence of major adverse cardiac events, was formed from five parameters obtained by multifactorial analysis. A probability cut off value of 0.61 was determined based on the obtained model. Conclusion:Echocardiographic parameters of the right ventricle are significant predictors of one-year major adverse cardiac events in patients with chronic heart failure with reduced ejection fraction. TAPSE / RVSP with a cut off value of 0.28 mm / mmHg was selected as the superior independent predictor of one-year adverse outcome.

Full textIntroduction: Patients on hemodialysis (HD) have a high general morbidity and all-cause mortality, as well as high cardiovascular morbidity and mortality. More than 80% of patients on HD have some cardiovascular disease. Hypervolemia plays a significant role here, contributing to hypertension, left ventricular hypertrophy, heart failure and pulmonary edema. Fluid status assessment in HD is still mostly clinical, despite having low specificity and sensitivity. A number of patients remain hypervolume, despite being normotensive, without edema or bibasilar crackles on lung auscultation. Different methods are used for volume status assessment in HD setting, no method without its flaws. Bioelectric impedance analysis requires expensive equipment and supplies. B type natriuretic peptide (BNP) values, and those of its terminal propeptide (NT-proBNP) depend on volume status, cardiac function as well as type of dialysis membrane used. Echocardiography (ECHO) and ultrasonography of inferior vena cava (IVC US) with measurements of its diameters in inspirum and expirium (IVCDi and IVCDe) require trained medical personnel. Lung ultrasound (LUS) is a simple, fast and inexpensive method for detection of extravascular lung water (EVLW), which is the water contained in the lung interstitium. LUS detects EVLW as ultrasonographic artefacts called „B lines“. EVLW is dependent on left ventricular filling pressures and is increased in volume overload, manifesting as more „B lines“ on LUS. The sum of all „B lines“ detected on predetermined places on the chest is called „B line score“ (BLS) and is used to quantify EVLW using LUS. Goal: Compare the adequacy and efficacy of LUS in assessment of volume status in patients on HD to other methods (IVC US, ECHO, BNP). Assess the possibility of simplifying LUS by reducing the number of examined lung fields. Materials and methods: A cross-section study was performed from April 2016 to June 2017. on 83 dialysis patients in Dialysis unit of Internal medicine department of General hospital Kikinda. LUS, ECHO, IVC US and blood sampling for BNP were performed on the first dialysis day of the week, just prior to HD. Patients were then dialyzed according to their dialysis protocols. After HD all tests were repeated, except blood sampling for BNP, which was sampled just prior to the next HD session in order to avoid elevated BNP values after HD. Variables were compared using double sample T test or Wilcoxon test. Correlation was assessed using Pearson’s or Spearman’s test, depending on variable distribution. Differences between groups were tested using one-way analysis of variance for continuous variables and contingency tables for categorical variables. Principal component analysis (PCA) was used to assess the possibility of lung field reduction. Results: There was a significant difference between BLS predialysis (pre HD) (mean 18,85) and BLS postdialysis (post HD) (mean 7,30); between IVCDe pre HD (mean 10,45 mm) and IVCDe post HD (mean 7,85 mm); between IVCDi pre HD (mean 7,20 mm) and IVCDi post HD (mean 4,41 mm); between CCI pre HD (mean 32%) and CCI post HD (mean 45%), between BNP pre HD (mean 894,89 pg/ml) and BNP post HD (mean 487,74 pg/ml). There was also a significant difference between the following ECHO parameters: left atrial diameter pre HD (mean 3,78 cm) and post HD (mean 3,53 cm), left ventricular internal diameter in diastole pre HD (mean 5,21 cm) and post HD (mean 4,96 cm) and left ventricular internal diameter in sistole pre HD (mean 3,69 cm) and post HD (mean 3,43 cm), left atrial volume in sistole pre HD (mean 60,54 ml) and post HD (mean 52,36 ml). All differences were significant at a level of p<0,0001. There was a significant positive correlation between BLS pre HD and BNP pre HD (ρ=0,49, p<0,01) and BNP post HD (ρ=0,43, p<0,01); BLS pre HD and IVCDe pre HD (ρ=0,29, p<0,01) IVCDi pre HD (ρ=0,30, p<0,05) and IVCDi post HD (ρ=0,23, p<0,05); between BLS post HD and BNP pre HD (ρ=0,44, p<0,01) and BNP post HD (ρ=0,42, p<0,01); between BLS post HD and IVCDe pre HD (ρ=0,29, p<0,05), IVCDi pre HD (ρ=0,33, p<0,05) and IVCDi post HD (ρ=0,23, p<0,05). Subjects with higher BLS had lower hemoglobin levels (p=0,006), higher troponin T levels (p=0,02) and greater left ventricular internal dimensions in sistole (p=0,04). PCA showed that there is a possibility of lung field reduction to 12 lung fields and even down to 4 lung fields, which would account for 84,51% or 75,38% of BLS variability. Conclusion: LUS can be used to adequately and effectively assess volume status in patients on HD. LUS is simple, fast and inexpensive exam with bedside capability, which gives accurate volume status data in real time. The exam can be implemented into dialysis unit protocols without difficulty. There is a possibility of simplifying LUS by reducing the number of examined lung fields. LUS can be used in assessment of cardiac function in patients on HD. Patients rated as hypervolemic by LUS have increased cardiovascular risk, as well as patients rated as hypervolemic by BNP levels or IVC diameters.

Full textObjective: The aim of this study was to determine the changes that arterial hypertension by its dual mechanisms (circadian rhythm and its duration) leaves on the function and geometry of left atrium and left ventricle of the heart. Respondents and Methods: This study involved 180 subjects who were divided into examined groups in relation to the circadian arterial blood pressure rhythm during 24-hour monitoring of arterial blood pressure, as follows: group of subjects with preserved circadian rhythm of arterial blood pressure consisted of a total of 90 subjects, and a group of those with impaired circadian rhythm of arterial blood pressure also comprised 90 subjects. In each of these groups an additional division of subjects was performed according to the duration of arterial hypertension to those whose arterial hypertension lasted up to 5 years, those in whom it lasted 5-10 years and those with duration of arterial hypertension for more than 10 years. All participants received an incisional 24-hour ambulatory monitoring of arterial blood pressure, followed by an echocardiographic examination to determine the morphology parameters of the left atrium and ventricle, as well as the diastolic functions of the left ventricle. Results and discussion: after statistical data processing, results have been obtained indicating that diastolic dysfunction of a level greater than I statistically significantly more frequently (p = 0.011) was observed in those subjects who didn’t have preserved circardian rhythm of arterial blood pressure. A non-dipper circadian arterial blood pressure rhythm also led to an increase in the indexed left ventricular myocardial mass according to the body surface of the respondent (LVM / BSA) - p = 0.001; to the increase in the wall thickness of the left ventricle (IVS / PLW) - p = 0.025, as well as to the decrease in systolic myocardial velocity at the level of the septal portion of the mitral anulus (s') - p <0.0005. In addition, in the group of those with impaired circadian rhythm of arterial blood pressure, a more frequent presence of eccentric hypertrophy of the left ventricular myocardium (p = 0.027) was observed. In relation to the geometry and left atrial function, the circadian rhythm of arterial blood pressure led to a change in terms of an increase in the antro-posterior diameter of the left atrium (LA) -p = 0.003; maximum left ventricular volume in ventricular systole (LAVs) -p = 0.007; indexed LAVs according to the surface of the respondent’s body (LAVs / BSA) -p <, 0005; E / e 'ratio-p = 0.040; reservoar strain (PLAS) - p = 0.004; stiffness -p = 0.047, as well as the velocity propagation across the mitral opening (Vp) -p = 0.029. With increasing duration of arterial hypertension, changes in morphology and left atrial and left ventricular functions were also demonstrated. Diastolic dysfunction of a grade greater than I was rarely observed in the group of those who had been treating arterial hypertension for up to 5 years, and its presence in the investigated groups with duration of 5 to 10 years and for more than 10 years was statistically significantly more common (p <0.0005). Also, with the duration of arterial hypertension, the parameters of the left ventricle were also significantly changed-the same for which we showed that they were worsened when the circadian rhythm of arterial blood pressure was not preserved, but beside that we noticed significant changes in the sense of the existence of less negative values of strain- the left ventricle global strain (LVGS) -p <0.0005. In a similar way to the circadial rhythm of arterial blood pressure, the prevalent form of myocardial left ventricular hypertrophy changed, and the presence of eccentric hypertrophy in patients with longer arterial hypertension duration was significantly more frequent (p = 0.017). In addition to these changes, with duration of arterial hypertension, changes in the following echocardiographic parameters of the left atrium (p <0.0005) were observed: LA, LAVs, LAVs / BSA, E / e ', PLAS, stiffness, Vp. Finally, a model for the diagnosis of diastolic dysfunction of a degree greater than I was formed and afterwards tested on 30 new subjects and it proved to be of good quality with high sensitivity and specificity. Conclusion: arterial hypertension by its duration and day-night oscillations (rhythm) leads to changes in the function and geometry of the left atrium and left ventricle of the heart. The latest echocardiographic parameters (PLAS, LVGS, stiffness) are good indicators of early changes of left atrium and left heart ventricle in patients with arterial hypertension.
