SENSITIVITY OF EXERCISE TOLERANCE TEST AND CORONARY ANGIOGRAPHY IN THE DIAGNOSIS OF CORONARY ARTERY DISEASES IN REHMAN MEDICAL INSTITUTE PESHAWAR

Abstract

Objective:
To determine and compare the sensitivity of the Exercise Tolerance Test (ETT) and Coronary Angiography (CA) in the diagnosis of coronary artery disease (CAD).

Methodology:
A cross-sectional observational study was conducted at the Cardiac Catheterization Laboratory and ECG/ETT Laboratory of Rehman Medical Institute (RMI), Peshawar. A total of 212 patients undergoing both ETT and coronary angiography were included using a non-probability convenient sampling technique. Data were analyzed using SPSS version 22.0.

Results:
The sensitivity of ETT in diagnosing CAD was 76.5%, while coronary angiography demonstrated a higher sensitivity of 89.7%. True positive findings were more frequent with coronary angiography compared to ETT, indicating superior diagnostic performance.

Conclusion:
Coronary angiography is a more sensitive diagnostic modality for detecting coronary artery disease than the Exercise Tolerance Test.
