Aim: Ischemic cardiac disease is the most common adult heart disease. The primary aim of the study was to analyze the myocardial perfusion status of the patients undergoing coronary artery bypass graft using sestamibi scan and assess the improvement in perfusion status of the myocardium after the surgery.

Materials And Methods: This study was a descriptive study consisting of a single group of patients undergoing elective surgery for coronary artery disease. The patients underwent myocardial perfusion scan before surgery. Another myocardial perfusion scan was performed 3 months after the surgery. The change in myocardial perfusion status was analyzed.

Results: Totally, 49 patients were initially included in this study. Seven patients lost their follow-up. Among the 17 patients who had severely reduced tracer uptake preoperatively, 3 (7.1%) had a good outcome, while 14 (33.3%) had a poor outcome, which was statistically significant ( < 0.001). Eighteen cases who belonged to the category of moderately reduced tracer uptake while analyzed, it was found that 16 (38.1%) had a good outcome while only 2 (4.8%) had a poor outcome; the difference in proportion among these two groups was statistically significant ( < 0.001). The patients who had mildly reduced tracer uptake preoperatively, all 3 (7.1%) had a good outcome, but it was not statistically significant ( = 0.23). Four patients had adequate tracer uptake preoperatively, out of which 3 (7.1%) had a good outcome, while the other 1 (2.4%) had a poor outcome and was not statistically significant ( = 0.63).

Conclusion: Surgical revascularization improves perfusion in a selective group of patients.
