The relation between blood and tissue magnesium levels and development of atrial fibrillation after coronary artery bypass surgery.

Objective: Atrial fibrillation (AF) is a common complication of cardiovascular surgery and its mechanisms are not well understood. The aim of our study was a prospective investigation of the relationship between AF development and tissue or blood magnesium levels.

Methods: This prospective observational study evaluated 20 patients undergoing elective initial coronary artery bypass graft (CABG) surgery.

Left ventricular giant pseudoaneurysm.

Left ventricular (LV) pseudoaneurysm is a rare complication of myocardial infarction. It may also occur as a complication of mitral valve surgery, chest trauma, and bacterial endocarditis. It forms when a cardiac rupture contains adherent pericardium or scar tissue and is typically located on the posterior or inferior LV wall.

Mortality predictors in ST-elevated myocardial infarction patients undergoing coronary artery bypass grafting.

The use of coronary artery bypass grafting (CABG) in primary treatment of acute myocardial infarction is still debated. We evaluated the predictors of mortality in patients undergoing primary CABG for ST-elevated myocardial infarction (STEMI). Between January 2003 and January 2008, all patients referred to our institution with STEMI who did not qualify for primary angioplasty and required CABG were included in this study.
