Acute coronary syndromes (ACS) comprise a spectrum of clinical conditions, initiated by rupture of an atherosclerotic coronary plaque with overlying acute thrombosis. This is from the buildup of fatty deposits (plaques) in the walls of coronary . Acute coronary syndromes, or "heart attacks," include unstable angina and acute myocardial infarction. Heart attack and unstable angina are both acute coronary syndromes (ACS). The goals of treatment include improving blood flow, treating complications and preventing future problems. However, current evidence suggests that a sole focus on plaque rupture obscures other mechanisms that may mandate different management strategies. There is also a change in the demographic characteristics and co-morbidities of the admitted patients.OBJECTIVES: The aim of this study is to illustrate the current causes of admission and complications during .
