The relationship between single and two-dimensional indices of left ventricular size using hemodynamic transesophageal echocardiography in trauma and burn patients

Critical Ultrasound Journal, 2017
Background Conventional echocardiographic technique for assessment of volume status and cardiac contractility utilizes left ventricular end-diastolic area (LVEDA) and fractional area of change (FAC), respectively.

A two phase harmonic model for left ventricular function [PDF]

arXiv, 2006
A minimal model for mechanical motion of the left ventricle is proposed. The model assumes the left ventricle to be a harmonic oscillator with two distinct phases, simulating the systolic and diastolic phases, at which both the amplitude and the elastic constant of the oscillator are different. Taking into account the pressure within the left ventricle,

Decursin‐Loaded Nanovesicles Target Macrophages Driven by the Pathological Process of Atherosclerosis

Advanced Science, EarlyView.
This study presents decursin, a traditional Chinese medicine monomer, that inhibits lipid accumulation and inflammation in atherosclerosis through PKCδ interaction. A novel targeted delivery system (ALD@EM) is developed to overcome decursin's short half‐life, combining antibody‐mediated targeting, LDL‐facilitated chemotaxis, and enhanced macrophage ...

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 ...

Improved ventricular function during inhalation of PGI(2) aerosol partly relies on enhanced myocardial contractility [PDF]

, 2005
Inhaled prostacyclin (PGI(2)) aerosol induces selective pulmonary vasodilation. Further, it improves right ventricular ( RV) function, which may largely rely on pulmonary vasodilation, but also on enhanced myocardial contractility.

Ventricular torsional relation to ventricular fiber arrangement [PDF]

arXiv, 2014
Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole.

Flavonifractor Plautii or Its Metabolite Desaminotyrosine as Prophylactic Agents for Alleviating Myocardial Ischemia/Reperfusion Injury

Advanced Science, EarlyView.
The gut microbiome is a potential target for treating cardiovascular disease. It is found that prophylactic administration of Flavonifractor plautii or its metabolite desaminotyrosine (DAT) exerts pleiotropic cardioprotective effects via promoting cardiomyocyte survival and attenuating cardiac inflammation against myocardial ischemia/reperfusion (I/R ...

Left ventricular dysfunction after open repair of simple congenital heart defects in infants and children: Quantitation with the use of a conductance catheter immediately after bypass [PDF]

, 1998
Objective: Quantification of myocardial injury after the simplest pediatric operations by load-independent indices of left ventricular function, using conductance and Mikro-Tip pressure catheters (Millar Instruments, Inc., Houston, Tex.) inserted through
