time since coronary even did not predict physical function score. patient age was related to baseline physical function score, with older patients having lower function. baseline maximal exercise capacity and peak Vo2 were the best univariate predictor of baseline physical function score. other significant predictor of baseline physical function score were strength measure of leg press and bench press,comorbidity score and depression score . Body mass index did not predict baseline physical function. The presence of angina or at least 1 mm ST segment depression at baseline stress test were not predictive of baseline physical function score. By multivariate analysis, baseline maximal exercise capacity and comorbidity score were best independent determinant of baseline physical function score
