Splitting the anterior mitral leaflet impairs left ventricular function in an ovine model

, 2023
OBJECTIVES: During mitral valve replacement, the anterior mitral leaflet is usually resected or modified. Anterior leaflet splitting seems the least disruptive modification.

The mortality for the implantable cardiac defibrillator in nonischemic cardiomyopathy: An updated systematic review and meta‐analysis

Clinical Cardiology, Volume 45, Issue 12, Page 1163-1170, December 2022., 2022
Abstract The implantable cardiac defibrillator (ICD) is common for the management of nonischemic cardiomyopathy (NICM). Mortality is a crucial issue for patients with NICM. We can understand the mortality events of ICD versus medicine treatment via a systemic review and meta‐analysis of randomized clinical trials.

Isolated chronic mitral regurgitation with preserved systolic left ventricular function and severe pulmonary hypertension [PDF]

, 1989
Pulmonary hypertension in chronic mitral valve disease has been related most commonly to left ventricular dysfunction or mitral stenosis; its association with chronic, isolated mitral regurgitation and preserved left ventricular systolic function is ...

Semantic-aware Temporal Channel-wise Attention for Cardiac Function Assessment [PDF]

arXiv, 2023
Cardiac function assessment aims at predicting left ventricular ejection fraction (LVEF) given an echocardiogram video, which requests models to focus on the changes in the left ventricle during the cardiac cycle. How to assess cardiac function accurately and automatically from an echocardiogram video is a valuable topic in intelligent assisted ...

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Association between serum cystatin C and early impairment of cardiac function and structure in type 2 diabetes patients with normal renal function

Clinical Cardiology, Volume 45, Issue 12, Page 1287-1296, December 2022., 2022
Abstract Background Type 2 diabetes mellitus (T2DM) patients may have cardiac remodeling and dysfunction from the early stage of disease. This study aimed to determine the association between cystatin C (CysC) and early cardiac functional or structural impairment in T2DM patients without renal dysfunction.

Early and late systolic wall stress differentially relate to myocardial contraction and relaxation in middle-aged adults: the Asklepios study [PDF]

, 2013
Experimental studies implicate late systolic load as a determinant of impaired left ventricular (LV) relaxation. We aimed to assess the relationship between the myocardial loading sequence and left ventricular (LV) contraction and relaxation.

DNA‐PKcs‐Driven YAP1 Phosphorylation and Nuclear Translocation: a Key Regulator of Ferroptosis in Hyperglycemia‐Induced Cardiac Dysfunction in Type 1 Diabetes

Advanced Science, EarlyView.
In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.

Prevalence, clinical characteristics, and predictors of sleep disordered breathing in hospitalized heart failure patients

Clinical Cardiology, Volume 45, Issue 12, Page 1311-1318, December 2022., 2022
Abstract Background Heart failure (HF) is often comorbid with sleep disordered breathing (SDB). This prospective study investigated the prevalence, clinical characteristics, and predictors of SDB in hospitalized HF patients. Methods Sleep studies were performed on hospitalized HF patients from January 2015 to February 2019.
