Background: This study was designed to evaluate the patterns of coronary artery disease in patients with chronic obstructive pulmonary disease (COPD) presenting with the acute coronary syndrome (ACS). Methods: This was a prospective, observational study, conducted on 69 patients with chronic obstructive pulmonary disease, presenting with acute coronary syndrome undergoing coronary angiogram from September 2017 to March 2021. All patients had undergone coronary angiogram; severity and morphology of lesion as well as the severity of calcium were analyzed. Results: The study showed that 69 patients with COPD who presented with ACS, 58.8% of patients were presented with NSTEMI, 30.2% STEMI and Unstable angina 11%. The average time of presentation after the onset of the symptom was 17.6 hours. 64% of patients were a smoker. Coronary involvement 10% of patients had LM, 50% TVD, 30% DVD, and 10% had SVD. Type a coronary lesion was seen in 5%, Type B in 20%, and Type C in 75% of patients. Mild Coronary calcium was seen in 25%. Moderate calcium was in 40% and severe calcium in 35%. Conclusions: COPD patients presenting with ACS, associated with increased severity of coronary calcium and coronary lesions.
