Effects of remote ischemic preconditioning on contrast induced nephropathy after percutaneous coronary intervention in patients with acute coronary syndrome.

Objective: The aim of this study was to explore the clinical effects of remote ischemic preconditioning (RIPC) on contrast-induced nephropathy after percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS).

Patients And Methods: The study was a single-center, prospective, randomized, controlled study. A total of 161 patients with ACS and the rate of estimate glomerular filtration (eGFR) 15 to 70 mL/min/1.

Apelin‑13 promotes cell proliferation in the H9c2 cardiomyoblast cell line by triggering extracellular signal‑regulated kinase 1/2 and protein kinase B phosphorylation.

Apelin‑13 (APL‑13), a peptide hormone that serves as a ligand for G‑protein coupled receptors, has been demonstrated to be highly expressed in left ventricular hypertrophy rat models. It has been implicated in cardio‑protection under pathological states. The present study aimed to assess the physiological proliferation effect of APL‑13 in cultured H9c2 cardiomyoblast cells, and to elucidate the underlying mechanisms.

Effect of prolonged intra-aortic balloon pumping in patients with cardiogenic shock following acute myocardial infarction.

Background: To evaluate the efficacy of prolonged intra-aortic balloon pumping (IABP) support in patients with cardiogenic shock following acute myocardial infarction (AMI).

Material/methods: Thirty-nine patients with cardiogenic shock after AMI were treated with percutaneous coronary intervention which was supported by IABP. After 72 hours of IABP, the patients who attained the criteria of IABP withdrawal were randomly divided into two groups.
