Sex differences in health status after coronary artery bypass surgery.

abstract：BACKGROUND:The main goal of the initial treatment of ST-segment elevation myocardial infarction is prompt reperfusion of the infarct-related artery. The value of pretreatment with clopidogrel before primary percutaneous coronary intervention is currently unclear. METHODS AND RESULTS:Studies were retrieved through MEDL...
