A RETROSPECTIVE DESCRIPTIVE STUDY ANALYSIS OF FREQUENCY OF TOTALLY OCCLUDED CORONARY ARTERIES IN PATIENTS OF STABLE IHD UNDERGOING ROUTINE CORONARY ANGIOGRAPHY

Abstract

Objective: To assess the current burden/frequency of chronic coronary total occlusions in patients with stable ischemic heart disease undergoing angiography at Army cardiac centre Lahore.

Study Design: Descriptive cross sectional study.

Place and Duration of Study: Army cardiac centre Lahore from Jan 2016 to Dec 2016.

Material and Methods: This is a retrospective descriptive study analysis of the record of 2441 patients who came to Army Cardiac Centre Lahore (ACC) for coronary angiography during the year of 2016. Patient’s data with completely (100%) occluded arteries (CTO) was analysed for age, gender, specific coronary artery occluded and co-morbidities like diabetes. The data was obtained from ACC registry and then tabulated.

Results: Out of 2441 patients 1753 were found to have stable IHD. Out of these 463 patients were found to have completely occluded arteries. Most common occluded artery was found to be proximal RCA followed by proximal LAD. About 84.7% patients with chronic coronary occlusion were males and 30.4% had diabetes.

Conclusion: Analysis of data revealed that 26.4% of patients with stable ischemic heart disease undergoing coronary angiography had completely occluded coronary arteries which indicate a significant burden, especially considering the morbidities, mortality and therapeutic challenges associated with CTO.
