Objective: The purpose of this study is to determine the incidence rate of Coronary Artery Ectasia in the patients and their angiographic traits. Methodology: This was an observational research work conducted in PIMS Hospital Islamabad. The duration of this study was from November 2015 to December 2018. We performed a follow up of two years to examine the primary as well as secondary endpoints. The collection of the data carried out from the clinical records of the patients. Results: Total 5000 coronary angiograms were conducted in the duration of this research work. A sum of 2.8% (n: 140) angiograms displayed the coronary ectasia of both pure as well as mixed types. Pure ectasia without coronary obstructive abrasions was present in 1.5% (n: 75) patients. The most frequent affected vessel was LAD (Left Anterior Descending) artery (63.0%) followed by RCA (Right Coronary Artery) 25.0% and 10.0% patients were present with the involvement of the circumflex artery. Primary endpoint stated 4.20% (n: 6) patients with non-ST myocardial infarction elevation, 3.60% (n: 5) patients with ST elevation inferior wall Myocardial Infarction, 50.0% (n: 70) were present with unstable angina and there were 1.40% (n: 2) deaths because of the pulmonary edema. The secondary endpoints stated that 50% patients were still complaining the pain in chest. Conclusion: The rate of incidence of coronary artery ectasia in the patients of this research work was 1.50%. Most of the patients were from male gender, having association with dyslipidemia, Hypertension and habit of cigarette smoking. There was association of the coronary artery ectasia with the disease of obstructive coronary artery in 80% patients. The most common affected vessel was Left Anterior Descending artery.
