Exercise capacity among cardiac patients is not sufficiently predicted using left ventricular ejection fraction resting measurement. The echocardiographic measurement using Wall Motion Score Index (WMSI) and Anatomical M-mode (AAM) Systolic Thickening post-myocardial infarction was studied to determine its correlation with functional capacity. We conducted a cross-sectional study of 33 consecutive post-MI patients. The inclusion criteria included heart failure patients with NYHA class I-II visiting the cardiology outpatient clinic of Soetomo Hospital, Surabaya. A resting echocardiogram, measuring WSMI and AMM systolic thickening of basal and mid-LV segments, was taken. The patients underwent a treadmill stress test using the Naughton protocol on the same day of their echocardiography examination. Samples were then analyzed using SPSS 2.0. Study subjects were 69.7% males with age 58.45±6.2 years old and BMI 24.07±3.2 kg/m 2 . The proportion of hypertension was 60.6%, smoking 51.5%, diabetes mellitus 42.4%, and dyslipidemia 42.4%. WMSI was 1.68±0.45, mean AMM systolic thickening 39±13%, and exercise capacity 3.69±1.8 METs. There was a moderate negative correlation of WMSI and a moderate positive correlation of AMM systolic thickening with functional capacity (r = –0.466, r = 0.415 consecutively; p<0.05). WMSI and AMM systolic thickening were correlated with functional capacity in post-MI patients with heart failure.
