Background: Increased neutrophil gelatinase-associated lipocalin (NGAL) levels are associated with toxic or ischemic renal injury.
Objective: This study aimed to assess the usefulness of serial NGAL measurements with a point-of-care assay in patients with left ventricular systolic dysfunction (LVSD) for earlier detection of contrast-induced nephropathy (CIN).
Materials And Methods: A total of 84 patients with LVSD patients referred for coronary angiography were consecutively enrolled in the study.
Background And Aims: Thiol/disulfide homeostasis has an important role in the antioxidant defense system. Oxidative stress may contribute to the pathogenesis of coronary artery ectasia. The aim of this study was to evaluate plasma thiol levels and thiol/disulfide homeostasis in patients with isolated coronary artery ectasia.

Vasoactive drug administration at the distal part of the coronary artery is suggested as a therapeutic option for no-reflow treatment. Here, we represent two cases of successful no-reflow management with previously used monorail balloon at the same procedure as a hand-made distal infusion catheter.

Here, our aim is to investigate the monocyte heterogeneity in acute ST elevation myocardial infarction (STEMI) and non-STEMI separately and determine any possible relationships between monocyte heterogeneity and coronary angiographic characteristics.
Methods: Thirty STEMI, 30 non-STEMI, and 25 stable angina pectoris patients were enrolled.
