Employing rest and exercise first‐pass radionuclide angiography before and 3 months after surgery, we studied patients with hemodynamically stable left ventricular aneurysm (LVA) undergoing both coronary artery bypass surgery to relieve angina pectoris and elective aneurysmectomy. There were 15 patients, 14 men and 1 woman with a mean age of 54 ± 7 years. All patients had anterior and/or apical LVA. After surgery the postexercise mean left ventricular ejection fraction (LVEF) for the whole group improved significantly (p<0.004) compared with the preoperative value, but the resting LVEF did not change. The duration of exercise improved (p< 0.01) after surgery, but not the double product. However, based upon the preoperative LVEF response to exercise, two groups were seen: Group A (n=5) had ≥5% increase in their LVEF with exercise versus Group B (n=10), who had <5% increase or a decrease in their LVEF. Postoperatively, Group A decreased their LVEF with exercise and failed to improve exercise capacity or double product. Postoperatively, Group B increased the LVEF by ≥5% as well as increasing exercise capacity (p<0.01), and double product (p<0.03). Group A had lower preoperative LVEF than Group B (p<0.01) and larger LVA. Patients with hemodynamically stable LVA who require coronary artery bypass surgery for angina should not have aneurysmectomy. The presence of hemodynamically stable LVA is not a contraindication to deriving benefit from myocardial revascularization.
