Abstract:

This retrospective study assessed the usefulness of a drop and a blunted systolic blood pressure (SBP) response to exercise testing as predictors of multiple or left main coronary artery disease (CAD) as defined by a 'Coronary Score' (CS). Three types of systolic BP response to exercise were used: (1) an increase by more than 20 mmHg (Group I, n = 107), (2) an increase by 20 mmHg or less (Group II, n = 84), and (3) a decrease of at least 10 mmHg (Group III, n = 45). The extent of CAD was significantly greater in groups II and III than in group I (group I, $6.7\pm6.9;$ group II, $9.3\pm7.1;$ gr

Abstract:

The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perf

Abstract:

Hypotension is the most common complication during anaesthesia of dogs and contributes to anaesthetic-related morbidity. The frequency of hypotension reported in anaesthetised dogs is quite variable due to the lack of a standardised definition of hypotension and the number of different factors present in each study that could influence the results. In addition, there is no study in the veterinary literature that has attempted to identify animal factors that may influence perioperative mean arterial blood pressure (MAP). The aims of this thesis were to document the proportion of healthy dog

Abstract:

Sepsis remains the second largest killer in the Intensive Care Unit (ICU), giving rise to a significant economic burden ($17b per annum in the US, 0.3% of the gross domestic product). The aim of the work described in this thesis is to improve the estimation of severity in this population, with a view to improving the allocation of resources. A cohort of 2,143 adult patients with sepsis and hypotension was identified from the MIMIC-II database (v2.26). The implementation of state-of-the-art models confirms the superiority of the APACHE-IV model (AUC=73.3%) for mortality prediction using ICU adm

Abstract:

Over the past decade, a large body of knowledge has been gathered with regard to the nocturnal hemodynamic pattern, as well as the comorbidity with sleep disturbances, in several cardiovascular diseases, such as hypertension. Nevertheless, surprisingly few attention has been paid to the hypotensives states. In particular, there is paucity of studies addressing sleep in essential hypotension. Essential hypotension represents a form of chronic low blood pressure that is not due to medical or orthostatic conditions. Unlike the other forms of hypotension and although sufferers endorse a variety

DPDPE Lowerd IOP in normal rabbits but not in sympathectomized (SX) eyes. Naloxone did not inhibit the effect of DPDPE on IOP in normal rabbits.

Abstract:

Hypotension är vanligt förekommande vid anestesi och i den postoperativa fasen. Om blodtrycket sjunker till för låga nivåer eller pågår under för lång tid kan vitala organ som hjärta och njurar ta allvarlig skada. De flesta fall av hypotension behandlas idag retroaktivt. Med möjlighet att kunna upptäcka hypotension innan det uppstår skulle behandling kunna ske i ett förebyggande syfte och på så sätt minska tiden i hypotension för patienten. Med hjälp av maskininlärning går det att analysera blodtryckskurvor och kunna hitta vilka attribut i dem som kan förutse hypotension. Detta projekt har gåt

Abstract:

Many senescent individuals demonstrate an inability to regulate mean arterial pressure (MAP) in response to standing or head-up tilt; however, whether this aging effect is the result of depressed cardiac function or an inability to reduce peripheral vascular conductance remains unknown. Therefore, the purpose of this research was to investigate the effects of aging on MAP, heart rate (HR), regional blood flow (via radioactive-microspheres), and vascular conductance during head-up tilt in conscious young (4 mo; n=12) and old (24 mo; n=10) male Fischer-344 rats. Heart rate and MAP were measured

Thesis (M Sport Sc (Sport Science))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: It is well-known that acute and chronic aerobic and resistance exercise results in decreased blood pressure (BP) in hypertensive individuals. There is little evidence that water exercise has a similar effect on BP response. There is also no certainty regarding the magnitude and duration of post exercise hypotension (PEH) after either land or water-based exercise.

Abstract:

Atrial Natriuretic Factor (ANF) is a cardiac peptide hormone that has been implicated in the regulation of blood pressure. The physiological role of ANF was investigated by generating transgenic mice (designated MT/ANF) that overexpress ANF in the circulation as well as at several ectopic sites, most notably in the pituitary and adrenal glands. Systolic blood pressure was significantly decreased in MT/ANF mice, but was not accompanied by any changes in heart rate, hematocrit, body weight, water or food intake, urine output, or sodium or potassium excretion.

Despite pharmacological advances, exercise remains a cost effective preventative for cardiovascular disease (CVD) by acutely and chronically lowering systolic blood pressure (SBP). Although numerous studies have investigated aerobic and resistance training’s role in eliciting an acute SBP response termed post-exercise hypotension (PEH), few researchers have investigated how performing both cardiovascular and weight training in a single session (concurrent training) or how different prescriptions for order of exercise modality will elicit this PEH response; no known studies have attempted alter

Abstract:

The relationship between hypertension and cardiovascular morbidity has long been recognised. However evidence is mounting implicating hypotension and not hypertension as the predominant risk factor for mortality. I demonstrated a 20-30% prevalence of intradialytic symptoms and hypotension in children during conventional, 4 hour haemodialysis (HD) sessions. The declining blood pressure (BP) was originally believed to be caused by ultrafiltration (UF) and priming of the HD circuit due to loss of fluid from the intravascular space. However data, largely in adults, challenged this hypothesis leadi
