Left ventricular ejection time: its relation to left ventricular systolic function and functional capacity in cardiomyopathic patients

Al-Azhar Assiut Medical Journal
Background and aim Left ventricular ejection time (LVET) was used to evaluate left ventricular function. Transthoracic echocardiogram was done, and parameters of LV systolic function by utilizing tissue Doppler imaging and two-dimensional strain were ...

Correlation of systolic and diastolic blood pressure with echocardiographic phenotypes of cardiac structure and function from three German population-based studies

Scientific Reports, 2023
Arterial hypertension is considered a risk factor for the development of heart failure. Here we investigate cross-sectional associations of systolic and diastolic blood pressure with subtle functional and morphological changes of left ventricular ...

The architecture of the left ventricular myocytes relative to left ventricular systolic function [PDF]

, 2017
Objective: Mural thickening, combined with longitudinal and circumferential shortening, and apical along with basal twisting are critical components of the left ventricular systolic deformation that contribute to ventricular ejection.

Gender differences in cardiac left ventricular mass and function: clinical and experimental observations [PDF]

, 2014
Background: The aim of this study was to evaluate gender-associated impact on left ventricular mass (LVM) and on left ventricular function (LVF) in humans and rats with aging. Methods: Myocyte area and collagen volume fraction (CVF) were studied in rats.

Early Outcomes After Total Arch Replacement With Frozen Elephant Trunk in Elderly Patients With Acute Type A Aortic Dissection

AGING MEDICINE, EarlyView.
Across seven centers (2015–2023), we studied 1634 ATAAD patients undergoing TAR+FET and, after propensity matching (n = 699), compared elderly (≥ 60) versus non‐elderly (< 60) outcomes. Elderly patients had higher 30‐day mortality and complications (log‐rank p = 0.002), supporting individualized hybrid strategies, organ‐protective perioperative care ...

PECULIAR FEATURES IN STRUCTURAL AND FUNCTIONAL HEART VALUES IN PERSONS WITH VARIOUS LEVELS OF BLOOD PRESSURE

Российский кардиологический журнал, 2002
113 healthy subjects with normal blood pressure and 26 patients with essential hypertension (BP 140-159/90-99 mm Hg) were inspected by echocardiography. All subjects were divided into 5 groups according to the blood pressure (BP) level.
