Role of left ventricular regional nonuniformity in hypertensive diastolic dysfunction [PDF]
Objectives. This study investigated 1) the role of left ventricular diastolic nonuniformity in hypertensive left ventricular diastolic dysfunction, and 2) the effect of a calcium channel antagonist on diastolic nonuniformity in hypertensive and ...

Initial studies of diastolic cardiac function in hypertension demonstrated that slowing of the maximal rate of left ventricular filling occurred before alterations in either ejection fraction or cardiac output. The present study was undertaken to determine: 1) the relation between hypertension, increased left ventricular mass and impaired left ...

Left ventricular pressure-volume relationship in a rat model of advanced aging-associated heart failure. [PDF]
Aging is associated with profound changes in the structure and function of the heart. A fundamental understanding of these processes, using relevant animal models, is required for effective prevention and treatment of cardiovascular disease in the ...

Geometric changes allow normal ejection fraction despite depressed myocardial shortening in hypertensive left ventricular hypertrophy [PDF]
Objectives.This study of hypertensive left ventricular hypertrophy 1) assessed myocardial shortening in both the circumferential and long-axis planes, and 2) investigated the relation between geometry and systolic function.Background.In hypertensive left

A method using deep learning to discover new predictors of CRT response from mechanical dyssynchrony on gated SPECT MPI [PDF]
Background. Studies have shown that the conventional left ventricular mechanical dyssynchrony (LVMD) parameters have their own statistical limitations. The purpose of this study is to extract new LVMD parameters from the phase analysis of gated SPECT MPI by deep learning to help CRT patient selection. Methods.

Primary left ventricular rehabilitation is effective in maintaining two-ventricle physiology in the borderline left heart [PDF]
ObjectiveBorderline left heart disease is characterized by left heart obstructive lesions (coarctation, aortic and mitral stenoses, left ventricular hypoplasia) and endocardial fibroelastosis.

A unique high-output cardiac hypertrophy phenotype arising from low systemic vascular resistance in Cantu syndrome [PDF]
Background Cardiomegaly caused by left ventricular hypertrophy is a risk factor for development of congestive heart failure, classically associated with decreased systolic and/or diastolic ventricular function.

A homogenized constrained mixture model of cardiac growth and remodeling: Analyzing mechanobiological stability and reversal [PDF]
Cardiac growth and remodeling (G&R) patterns change ventricular size, shape, and function both globally and locally. Biomechanical, neurohormonal, and genetic stimuli drive these patterns through changes in myocyte dimension and fibrosis. We propose a novel microstructure-motivated model that predicts organ-scale G&R in the heart based on the ...

Abstract Background As previously reported, an increased repolarization temporal imbalance induces a higher risk of total/cardiovascular mortality. Hypothesis The aim of this study was to assess if the electrocardiographic short period markers of repolarization temporal dispersion could be predictive of the hospital stay length and mortality in ...
