Deactivation in the rabbit left ventricle induced by constant ejection flow [PDF]

open access: yes, 1989
A study of pressure generated by the left ventricle after ejection with constant flow for different values of the ejection flow, flow duration, time of flow arrest, and ventricular volume is discussed.

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

open access: yesLife, 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

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

open access: yesJournal 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)

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

open access: yesVeterinary 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

open access: yesCardiovascular 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 ...

Left ventricular dysfunction in COPD without pulmonary hypertension.

open access: yesPLoS ONE, 2020
ObjectivesWe aimed to assess prevalence of left ventricular (LV) systolic and diastolic function in stable cohort of COPD patients, where LV disease had been thoroughly excluded in advance.Methods100 COPD outpatients in GOLD II-IV and 34 controls were ...

Diaspirin cross-linked hemoglobin fails to improve left ventricular diastolic function after fluid resuscitation from hemorrhagic shock [PDF]

open access: yes, 2001
In severe hemorrhagic shock, left ventricular (LV) diastolic dysfunction is an early sign of cardiac failure due to compromised myocardial oxygenation.

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

open access: yesJournal 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]

open access: yesPLoS 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)
