Abstract

To assess the role of a left ventricular aneurysm (VA) in affecting cardiac pump function, 36 patients with an echo-proved postmyocardial infarction (MI) VA underwent maximal symptom limited exercise testing. A control group was formed of 36 patients with a previous MI without VA. The two groups were matched for age, sex, and site of MI. No difference was found in maximal work capacity (MWC), heart rate (HR), systolic blood pressure (BP), ΔHR/kpm, ΔBP and VO2(max)/kg during exercise. MWC in patients with VA and anterior MI was lower as compared to patients with VA and inferior MI (2,839.3 ± 1,340.9 vs. 4,537.5 ± 1,453.7, p <0.05) while no difference was found between anterior and inferior MI without VA. Patients with VA and anterior MI tolerated lower workloads as compared to those with anterior MI without VA (2,839.3 ± 1,340.9 vs. 3,996.4 ± 2,347.1, p <0.05). No difference was found between patients with inferior MI with or without VA. No major adverse cardiovascular events occurred during or after the tests. Patients were grouped for echo-estimated ejection fraction (EF) 50%. Only 1 patient without VA was found among patients with EF
