Ischemic postconditioning reduces infarct size and microvascular obstruction zone in acute ST-elevation myocardial infarction - a randomized study.

Introduction: Ischemic postconditiong (postcon) has been reported to reduce infarct size in ST-segment myocardial infarction (STEMI). However, recently a few other studies did not show any effect of postcon or suggested that it may even be harmful.

Aim: We sought to assess whether postcon could reduce infarct size (IS) and the microvascular obstruction (MVO) zone in early presenters with STEMI.

Comparison of diffusion-weighted with T2-weighted imaging for detection of edema in acute myocardial infarction.

Background: Recent studies, performed with the use of a commercially available diffusion weighted imaging (DWI) sequence, showed that they are sensitive to the increase of water content in the myocardium and may be used as an alternative to the standard T2-weighted sequences. The aim of this study was to compare two methods of myocardial edema imaging: DWI and T2-TIRM.

Methods: The study included 91 acute and post STEMI patients.

Relations of diabetes mellitus, microvascular reperfusion and left ventricular remodelling in patients with acute myocardial infarction treated with primary coronary intervention.

Background And Aim: The aim of our study was to determine the influence of diabetes mellitus (DM) on myocardial reperfusion and left ventricular (LV) remodelling in patients with an acute myocardial infarction undergoing primary percutaneous coronary intervention.

Methods: The study population consisted of 218 patients with first anterior ST-segment elevation myocardial infarction (STEMI) successfully treated with primary coronary angioplasty. We evaluated microvascular reperfusion using angiographic (Myocardial Blush Grade [MBG]) as well as electrocardiographic methods (ST-segment resolution > 70%).
