Frequency and complications of ischemic mitral regurgitation in patients with acute coronary syndrome

Objective: to determine the frequency of ischemic mitral regurgitation,determine severity and defining its complications among patients with acute myocardial infarction (mi). methodology: this study was conducted at hayatabad medical complex. our study was descriptive cross sectional study in which 262 patients with acute mi were studied using non-probability consecutive sampling technique. complications were followed for 6 months & recorded on a pre-designed proforma. results: in this study mean age was 60 ±1.26 years. one hundred and ten (42%) patients were male while 152(58%) patients were female. one hundred thirty six patients (52%) patients were st elevation mi (stemi) and 126(48%) patients were non-st elevation mi (nstemi). mitral regurgitation was found in 141(54%) patients in whom 104(74%) patients were found to have mild mitral regurgitation,29(20%) patients were found to have moderate mitral regurgitation and 8(6%) patients were having severe mitral regurgitation. moreover 25(18%) patients had new onset atrial fibrillation,24(17%) patients had in-hospital mortality and 15(11%) patients were re-admission with heart failure. conclusion: following myocardial infarction,baseline mitral regurgitant severity is associated with deterioration of lv function & increased mortality. the presence of mitral regurgitation confers poor prognosis in patients with acute coronary syndrome. © 2017,postgraduate medical institute. all rights reserved.
