Pressure overload is associated with right ventricular dyssynchrony in heart failure with reduced ejection fraction

ESC Heart Failure, Volume 11, Issue 2, Page 1097-1109, April 2024.
Abstract Aims The determinants and relevance of right ventricular (RV) mechanical dyssynchrony in heart failure with reduced ejection fraction (HFrEF) are poorly understood. We hypothesized that increased afterload may adversely affect the synchrony of RV contraction.

Pulmonary Venous Index as Additional Diagnostic Criteria for Fontan Palliation

Journal of Cardiac Surgery, Volume 2024, Issue 1, 2024.
Backgroud. The results of the Fontan operation, depending on the anatomy of the pulmonary arteries, have been studied quite well. Various indices have been proposed to assess the degree of hypoplasia of the pulmonary arterial bed (Nakata, Reddy, and McGoon indexes).

Clinical Study to Individual Treatment for Major Aortopulmonary Collaterals of Tetralogy of Fallot

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Objectives. To build a guideline for the individual treatment of Tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) and tentatively establish the occlusion index of MAPCAs. Methods. According to the diameter of the aortopulmonary collaterals (R: mm) and the bodyweight of the children (weight: kg), K= ((∑R2)/Wt) was set as the ...

The use of invasive techniques, angiography and indicator dilution, for quantification of valvular regurgitations [PDF]

, 2017
Angiographic techniques have been used for the quantification of mitral or aortic and rarely tricuspid regurgitation. Mitral or aortic regurgitant volume per beat and the regurgitation fraction (fao and fm, respectively) are obtained from the ...

A Bibliometric Analysis of Study of Associations of Certain Genotypes with the Cardiovascular Form of Diabetic Neuropathy

BioMed Research International, Volume 2024, Issue 1, 2024.
This bibliometric analysis explores the landscape of research on the associations between specific genotypes and the cardiovascular form of diabetic neuropathy. Diabetes mellitus (DM) is a major contributor to premature mortality, primarily due to increased susceptibility to cardiovascular diseases.

Tetramethylpyrazine Prevents Contrast‐Induced Nephropathy via Modulating Tubular Cell Mitophagy and Suppressing Mitochondrial Fragmentation, CCL2/CCR2‐Mediated Inflammation, and Intestinal Injury

Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Contrast‐induced nephropathy (CIN) is a leading cause of hospital‐acquired acute kidney injury (AKI), but detailed pathogenesis and effectual remedy remain elusive. Here, we tested the hypothesis that contrast media (CM) impaired mitochondrial quality control (MQC) in tubules, including mitochondrial fragmentation and mitophagy, induced systemic ...
