Bivalirudin vs heparin in cardiac-cerebral ischemic and bleeding events among Chinese STEMI patients during percutaneous coronary intervention: a retrospective cohort study.

Although bivalirudin has been recently made available for purchase in China, large-scale analyses on the safety profile of bivalirudin among Chinese patients is lacking. Thus, this study aimed to compare the safety profile of bivalirudin and heparin as anticoagulants in Chinese ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI). A total of 1063 STEMI patients undergoing PCI and receiving bivalirudin (n=424, bivalirudin group) or heparin (n=639, heparin group) as anticoagulants were retrospectively enrolled.

Comparison of net adverse clinical events between bivalirudin and heparin as anticoagulants for percutaneous coronary intervention in Chinese patients.

Bivalirudin, as a direct thrombin inhibitor, is considered to be safer compared with other anticoagulants, such as heparin; however, relevant data in China are unclear. The present study aimed to compare the safety of bivalirudin and heparin as anticoagulants in Chinese patients who underwent percutaneous coronary intervention (PCI). In the present study, 2,377 patients with ST-segment elevation myocardial infarction (STEMI), unstable angina, non-STEMI or stable coronary artery disease who underwent primary PCI while receiving bivalirudin or heparin (low molecular weight heparin or unfractionated heparin) were reviewed, and then analyzed as the bivalirudin group (n=944) and heparin group (n=1,433).

MicroRNA-34a in coronary heart disease: Correlation with disease risk, blood lipid, stenosis degree, inflammatory cytokines, and cell adhesion molecules.

Background: MicroRNA-34a (miR-34a) plays an essential role in regulating blood lipid, inflammation, cell adhesion molecules, and atherosclerosis, the latter factors are closely involved in the etiology of coronary heart disease (CHD). However, the clinical value of miR-34a in CHD patients' management is rarely reported. Hence, this study aimed to assess the correlation of miR-34a with disease risk, blood lipid, coronary artery stenosis, inflammatory cytokines, and cell adhesion molecules of CHD.

MicroRNA-130a Increases and Predicts Cardiotoxicity during Adjuvant Chemotherapy in Human Epidermal Growth Factor Receptor-2-Positive Breast Cancer.

Purpose: This study aimed to investigate the changes in microRNA-130a (miR-130a) and its correlation with cardiotoxicity during epirubicin/cyclophosphamide followed by docetaxel plus trastuzumab (EC-D+T) adjuvant chemotherapy in human epidermal growth factor receptor-2-positive (HER2⁺) breast cancer patients.

Methods: A total of 72 HER2⁺ breast cancer patients who underwent resection and were scheduled to receive EC-D+T adjuvant therapy were consecutively enrolled. The expression of miR-130a and cardiotoxicity (defined as any of the following situations: 1) absolute decline of left ventricular ejection fraction (LVEF) ≥ 10% and LVEF < 53%; 2) heart failure; 3) acute coronary artery syndromes; and 4) fatal arrhythmia) were assessed every 3 months throughout the 15-month EC-D+T treatment.
