QTc interval prolongation and risk of atrial fibrillation recurrence: a meta-analysis and observational cohort study.

Introduction: Corrected QT interval (QTc) is a ventricular repolarization marker on electrocardiography. Previous studies evaluated its value in predicting atrial fibrillation (AF) occurrence. However, its predictive efficacy for AF recurrence remains controversial.

circ_TGFBR2 Inhibits Vascular Smooth Muscle Cells Phenotypic Switch and Suppresses Aortic Dissection Progression by Sponging miR-29a.

Background: Aortic dissection (AD) is a threatening and catastrophic vascular disease with high mortality rate and limited therapeutic strategies. There is emerging evidence showing that circular RNAs play crucial role in regulating various cardiovascular diseases. However, the biological functions and molecular mechanisms of circRNAs in AD still remains elusive.

Circ_nuclear factor I X (circNfix) attenuates pressure overload-induced cardiac hypertrophy via regulating miR-145-5p/ATF3 axis.

Cardiac hypertrophy can cause heart failure. However, the mechanisms underlying the progression of cardiac hypertrophy remain unclear. Emerging evidence suggests that circular RNAs (circRNAs) play a critical role in cardiac hypertrophy.

Erratum: Donor-derived exosomes induce specific regulatory T cells to suppress immune inflammation in the allograft heart.

This corrects the article DOI: 10.1038/srep20077.

Prolactin mediates effects of chronic psychological stress on induction of fibrofatty cells in the heart.

Cardiocyte apoptosis plays an important role in the pathogenesis of heart diseases. The mechanism is unclear. It is reported that prolactin (PRL) is involved in cardiac disorders.

One-stop hybrid coronary revascularization versus off-pump coronary artery bypass in patients with diabetes mellitus.

Objectives: To compare in-hospital and midterm outcomes after one-stop hybrid coronary revascularization (HCR) and off-pump coronary artery bypass (OPCAB) in patients with diabetes mellitus (DM).

Methods: The series included 120 patients with DM who underwent one-stop HCR at Fuwai Hospital between June 2007 and September 2014. These patients were 1:2 matched with 240 patients who underwent OPCAB using propensity score matching.

Donor-derived exosomes induce specific regulatory T cells to suppress immune inflammation in the allograft heart.

To inhibit the immune inflammation in the allografts can be beneficial to organ transplantation. This study aims to induce the donor antigen specific regulatory T cells (Treg cell) inhibit the immune inflammation in the allograft heart. In this study, peripheral exosomes were purified from the mouse serum.

Processing of the explanted heart.

Analysis of the explanted hearts from heart transplant recipients provides valuable clinical samples, which can be used to study the anatomy and pathology of the heart. PubMed database was employed as the article source of this review. This article summarized the processing methods of the explanted heart, including dissection, histopathologic examination, cryopreservation, and genetic testing.
