Abstract
Background: Chest pain at rest is one of the most frequent symptoms of patients in the emergency room . The diagnosis of acute coronary syndrome (ACS) is suspected in these patients, especially when typical electrocardiographic (ECG) changes and/or elevation of cardiac markers can be detected. However, of all patients who undergo coronary angiography because of suspected ACS, up to 30% have unobstructed coronary arteries or at least no culprit lesion that could explain the patient{u2019}s discomfort. Objectives: Aim of this Study is to determine the prevalence of normal or near normal coronary arteries among population subjected to coronary angiography specifically among patients with acute coronary syndrome. Results: Our study showed the prevalence of normal or near normal coronary angiograms to be 14.7% (38 patients) of the 259 admitted patient presenting with acute coronary syndrome We compared the prevalence of normal or near normal angiograms in both patients presenting with ST elevation myocardial infarction and those presenting with Non ST elevation ACS .We found no patients presenting with STEMI who had normal coronary angiograms.We found only 2 patients presenting with NSTEMI with normal coronary angiography. Stratification of all ACS patients admitted according to the commonly known risk factors (Diabetes mellitus, hypertension, dyslipidemia, smoking and positive family history of coronary artery disease). It was found that the most frequent risk factor was Hypertension (52.12%), D.M. (50.97 %), smoking (46.72%), Dyslipidemia (35.14%) and lastly positive family history of CAD in (13.9%) of ACS patient admissions.
