Early vs. late reverse ventricular remodeling in patients with cardiomyopathy.

Background: Predictors of left ventricular reverse remodeling (LVRR) and differences in the time taken to achieve LVRR remain unclear.

Methods: We consecutively registered 129 patients with severe cardiomyopathy admitted with heart failure (HF). Patients were followed for a median of 778.

Successful resolution of a left ventricular thrombus with apixaban treatment following acute myocardial infarction.

A 62-year-old man was admitted to our emergency department owing to prolonged chest pain that had lasted for 3 h. An electrocardiogram showed ST elevation in leads I, aVL, and V1-6, and the patient's laboratory revealed elevated myocardial necrosis marker levels. Emergency coronary angiography showed total occlusion of the proximal left anterior descending coronary artery.

Significance of AT1 receptor independent activation of mineralocorticoid receptor in murine diabetic cardiomyopathy.

Background: Diabetes mellitus (DM) has deleterious influence on cardiac performance independent of coronary artery disease and hypertension. The objective of the present study was to investigate the role of the renin-angiotensin-aldosterone system, especially angiotensin II type 1a receptor (AT1aR) and mineralocorticoid receptor (MR) signaling, in left ventricular (LV) dysfunction induced by diabetes mellitus (DM).

Methods And Results: DM was induced by intraperitoneal injection of streptozotocin (200 mg/kg BW) in wild-type (WT) or AT1aR knockout (KO) male mice, and they were bred during 6 or 12 weeks.

Elevated troponin T on discharge predicts poor outcome of decompensated heart failure.

Persistent elevation of cardiac troponin T (cTnT) predicts an adverse clinical outcome in patients with chronic heart failure (HF), but the underlying mechanisms remain to be determined. We investigated the association between predischarge cTnT elevation and coexistent pathophysiology in patients with decompensated HF. Plasma cTnT levels were determined before discharge in 170 patients with decompensated HF.
