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

Journal 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)

CD74 Blockade Disrupts Endothelial Migrasome Signaling to Prevent Inflammatory Macrophage Differentiation and Inhibit Atherosclerotic Progression

Advanced Science, EarlyView.
Migrasomes play a crucial role in endothelial‐immune interactions in atherosclerosis. This study identifies migrasomes as amplifiers in the inflammatory cascade, driving immune‐metabolic reprogramming via “migrasome‐APP‐CD74” signaling. Blocking CD74 disrupts migrasome‐mediated signaling, attenuating atherosclerosis progression.

Associations of Left Ventricular Structure and Function With Blood Pressure in Heart Failure With Preserved Ejection Fraction: Analysis of the TOPCAT Trial

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Data on the association of systolic and diastolic blood pressure with the structure and function of failing hearts with preserved ejection fraction (EF) are sparse. Methods and Results This analysis included 935 patients with heart failure (49.

Mechanisms of exercise-induced improvements in the contractile apparatus of the mammalian myocardium [PDF]

, 2010
One of the main outcomes of aerobic endurance exercise training is the improved maximal oxygen uptake, and this is pivotal to the improved work capacity that follows the exercise training.

Activation of Spinal Astrocyte α2A Adrenoceptors Protects Against Sepsis‐Induced Heart Injury Through Inhibition of GABAergic Neuronal Necroptosis

Advanced Science, EarlyView.
The study in this paper found that activating the α2A receptors of astrocytes in the thoracic spinal cord can reduce the release of inflammatory factors, thereby decreasing the necroptosis of GABAergic neurons and consequently alleviating myocardial injury caused by sepsis.

ER‐phagy Activation by AMFR Attenuates Cardiac Fibrosis Post‐Myocardial Infarction via mTORC1 Pathway

Advanced Science, EarlyView.
By catalyzing FAM134B ubiquitination and activating ER‐phagy, AMFR alleviates progressive fibrosis and cardiac dysfunction by inhibiting the mTORC1 pathway. Consequently, these findings underscore the essential role of AMFR‐driven ER‐phagy in mitigating the progression of fibrotic responses, offering a potential therapeutic target for preventing heart ...

Molecular Creep Induced Fatigue Rupture of Fibrin Clots

Advanced Science, EarlyView.
Fibrin networks in thrombi paradoxically exhibit low fatigue resistance despite high fracture energy, as cyclic loading triggers irreversible α‐to‐β transitions in fibrin molecules, causing molecular creep, crack propagation. Multiscale experiments, modeling reveal how nanoscale conformational damage accumulates, linking molecular disorder to ...

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...
