Cardiac biomarkers (NT-proBNP and cardiac troponin-I) and point-of-care ultrasound in dogs with cardiac and non-cardiac causes of non-hemorrhagic ascites
… Non-hemorrhagic ascites (NHA) can be caused by cardiac diseases (cNHA) and non-cardiac diseases (ncNHA). N-terminal brain natriuretic peptide (NT-proBNP), cardiac troponin-I (cTnI) and point-of-care ultrasound (POCUS) may differentiate between cNHA and ncNHA. Hypothesis/Objectives: This study …

Stabilization of the Cardiac Nervous System During Cardiac Stress Induces Cardioprotection
<p>The cardiac nervous system consists of nested reflex feedback loops that interact to regulate regional heart function. Cardiac disease affects multiple components of the cardiac nervous system and the myocytes themselves. This study aims to determine: 1) how select components of the cardiac …

Mechanisms by which cardiac resynchronisation therapy improves cardiac performance in heart failure
… and left ventricular pacing improves cardiac performance in patients with heart failure. We demonstrated for the first time that CRT results in an improvement in acute haemodynamic variables in heart failure patients with a narrow QRS duration that is comparable to the effects seen in …

Computerized cardiac mapping system.
… the results of the work on a computerized cardiac mapping system for recording simultaneously the signals from three electrodes placed at different sites on the heart in order to diagnose the sites causing arrhythmias. The signals are buffered, amplified, filtered and transferred to a …

Hydrodynamics of Cardiac Diastole
… to both the fundamental mechanics of the cardiac diastolic filling as well as the development of novel and accurate diagnostic techniques. This work includes studies of in-vivo and in-vitro vortex rings. Vortex rings created in the left ventricle past the mitral valve during diastole are …

ABSENCE OF V1AR ALTERS CARDIAC FUNCTION AT BASELINE AND FOLLOWING ACUTE CARDIAC INJURY
… with neurohormonal responses to the decrease in cardiac output and systemic blood pressure, such as the activation of the renin-angiotensin-aldosterone system (RAAS) and the sympathetic nervous system. Current treatment guidelines recommend using drugs that block β-adrenergic receptor (βAR) …

Cardiac PI3Kα Signaling and K+ Channel Regulation in Cardiac Hypertrophy and Heart Failure
Pathologic biomechanical stresses cause cardiac hypertrophy, which is associated with QT prolongation and increased risk of life-threatening ventricular arrhythmias. Previous studies demonstrated that repolarizing K<super>+</super> current densities are decreased in pressure overload-induced left …

Development of cardiac patches using medium chain length polyhydroxyalkanoates for cardiac tissue engineering
… that make them exceptional for applications in cardiac tissue engineering. Cardiovascular diseases (CVD) are a major cause of death worldwide. Cardiac patches aim to facilitate the normal functioning of the heart muscle by providing repair and support to the infarcted tissue post myocardial …

Market Analysis of Cardiac Electrical Mapping Platform in the Cardiac Resynchronization Therapy Market
This thesis will provide a market analysis for a cardiac electrical mapping system with an overview of the circulatory system, physiology of the heart and cardiac arrhythmias and the technology platform of the application. The ECVue system is based on electrocardiographic imaging (ECGI) that …

Efficacy of Cardiac Education on Dietary Habits of Subjects Participating in Cardiac Rehabilitation.
<p>The purpose of this study was to determine if cardiac nutrition education can affect dietary patterns of subjects participating in Cardiac Rehabilitation. Surveys, a pretest given prior to the first cardiac class and a second identical test, administered following cardiac rehabilitation classes, …

The Experiences of Partners of Cardiac Patients: Sense of Coherence and Cardiac Beliefs
The cardiac literature has shown that the stress of a patient’s illness may increase the partner’s vulnerability to develop psychological and physical illness. However, not all partners experience a crisis in response to the patients’ illness. The following study explored the experiences of being a …

Cardiac organoid technology and computational processing of cardiac physiology for advanced drug screening applications
… as the heart. Previous work in stem cell-derived cardiac tissue has exploited how we can engineer biologically functional heart tissue by providing the appropriate external stimuli to facilitate tissue development. The goal of this dissertation is to explore the potentials of stem cell cardiac …

Plasma proteins and cardiac oedema
One of the factors in the causation of cardiac oedema is a depletion of the plasma proteins which results in a fall in the colloid osmotic pressure of the blood. This depletion is due principally to malnutrition, and it is suggested that cases of cardiac oedema should be given diets containing the …
