Low and High Pressor Doses of Ang II Lead to Two Distinct Phenotypes of Hypertensive Heart Disease in Mice. [PDF]

APMIS
ABSTRACT Hypertension is a major contributor to cardiovascular diseases, being the most common comorbidity and the biggest risk factor in heart failure with preserved ejection fraction. Angiotensin II (Ang II) is a known hypertension and heart failure inducer in mice, but its role in the causality in phenotype development remains unclear.

Analysis of Right Ventricular Myocardial Stiffness and Relaxation Components in Children and Adolescents With Pulmonary Arterial Hypertension

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundThe rate of left ventricular pressure decrease during isovolumic relaxation is traditionally assessed algebraically via 2 empirical indices: the monoexponential and logistic time constants (τE and τL). Since the pattern of right ventricular (RV)

Parkinson’s Disease and the Cardiac Cycle: A Rapid Literature Review and Case Series

Life, 2023
Background and Objectives: Cardiac function in patients with Parkinson’s Disease (PD) is not well understood. We conducted a review of the literature to summarize all available data on the cardiac cycle in patients with PD and followed up the review with

Prevalence of cardiac myosin-binding protein C3 mutations in Maine Coon cats with hypertrophic cardiomyopathy [PDF]

Veterinary World, 2022
Background and Aim: Hypertrophic cardiomyopathy (HCM) is a common heart problem that affects many cats. Although cats with HCM are symptomatic, some die suddenly or develop congestive heart failure.

Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricle

Cardiovascular Ultrasound, 2006
Background The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering ...

Novel Findings From a Metabolomics Study of Left Ventricular Diastolic Function: The Bogalusa Heart Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Diastolic dysfunction is one important causal factor for heart failure with preserved ejection fraction, yet the metabolic signature associated with this subclinical phenotype remains unknown.

Cardiac Time Intervals by Tissue Doppler Imaging M-Mode: Normal Values and Association with Established Echocardiographic and Invasive Measures of Systolic and Diastolic Function. [PDF]

PLoS ONE, 2016
PURPOSE:To define normal values of the cardiac time intervals obtained by tissue Doppler imaging (TDI) M-mode through the mitral valve (MV). Furthermore, to evaluate the association of the myocardial performance index (MPI) obtained by TDI M-mode (MPITDI)
