Tissue Doppler echocardiographic quantification. Comparison to coronary angiography results in Acute Coronary Syndrome patients

Cardiovascular Ultrasound, 2005
Background Multiples indices have been described using tissue Doppler imaging (DTI) capabilities. The aim of this study was to assess the capability of one or several regional DTI parameters in separating control from ischemic myocardium.

B‐Type Natriuretic Peptides Levels in Patients With Beta‐Thalassemia Major and Correlations With Biomarkers: A Systematic Review and Meta‐Analysis

Health Science Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background Patients with beta‐thalassemia major are prone for developing cardiovascular complications. Early identification of patients at risk is important. B‐type natriuretic peptides such as brain natriuretic peptide (BNP) and N‐terminal pro‐BNP (NT‐proBNP) are sensitive indicators of cardiac dysfunction.

Stabilisation of PRCP by deubiquitinase‐targeting chimera (DUBTAC) to replenish autophagy for ameliorating pathological cardiac hypertrophy

British Journal of Pharmacology, Volume 182, Issue 21, Page 5317-5339, November 2025.
Background and Purpose Autophagy is essential for cellular homeostasis, and its impairment contributes to cardiac hypertrophy. Modulating autophagy has shown potential in treating pathological hypertrophy. Prolylcarboxypeptidase (PRCP), a lysosomal enzyme that hydrolyzes angiotensin II to Ang1‐7, has an unclear role in cardiac autophagy and hypertrophy.

Prognostic Value of Right Ventricular Global Wasted Work in Precapillary Pulmonary Hypertension: A 3D Echocardiographic Study

Echocardiography, Volume 42, Issue 11, November 2025.
Graphical abstract displaying (A) RV pressure–strain loop in patient with decompensated RV function, (B) progressive decrease in RV global wasted work (GWW) with increasing RV–PA uncoupling, and (C) Kaplan–Meir survival curves displaying association of higher GWW with poorer clinical outcomes.

Effects of CPAP on right ventricular myocardial performance index in obstructive sleep apnea patients without hypertension

Respiratory Research, 2006
Objectives Obstructive sleep apnoea (OSA) might cause right ventricular dysfunction and pulmonary hypertension. We aimed to determine the effects of nasal continuous positive airway pressure (CPAP) therapy on right ventricular myocardial performance ...

Left ventricular untwist determines intradialytic hemodynamics and outcomes in mildly reduced and preserved ejection fraction patients

Physiological Reports, Volume 13, Issue 21, November 2025.
In patients undergoing hemodialysis with mildly reduced or preserved left ventricular ejection fraction, stronger diastolic LV untwisting supports blood pressure maintenance and is associated with improved survival. Impaired untwist, reflecting delayed diastolic recoil, predisposes to intradialytic hypotension and adverse outcomes.

Mitral flow propagation velocity in non-sedated healthy cats

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
Mitral flow propagation velocity (Vp) is an index used to evaluate the left ventricular diastolic function. Its influence on human and small animal cardiopathies has been studied; however there are few reports evaluating this variable in domestic felines.

Fibroblast Has2 limits acute heart failure following myocardial infarction in male mice

Physiological Reports, Volume 13, Issue 22, November 2025.
Abstract Changes to the extracellular matrix support acute wound healing following myocardial infarction. Fibroblasts regulate the composition of the extracellular matrix, in part, by secreting hyaluronan. Details surrounding the regulation, source, and impact of hyaluronan production after MI are largely unknown.
