This study compared the clinical profile and outcome between men and women admitted to phase I (In-patient) of the Comprehensive cardiac rehabilitation Program (CCReP) after coronary artery bypass graft (CABG) surgery at the Philippine Heart Center from January 1,2000 up to September 15, 2000. A retrospective chart review was done. Out of the 174 post-CABG surgery patients referred to the CCReP, 103 had complete entry of data. Eleven patients were excluded based on the exclusion criteria and only 92 patients ( 77 men and 15 women) were finally included in the study. Men and women were compared for differences in age, cardiovascular risk factors, history of previous myocardial infarction (MI), congestive heart failure (CHF), revascularization procedures, number of coronary vessels involved and bypassed, medications taken, number of days from surgery to admission (DAYSSR) to the CCReP, length of stay (LOS) on the rehabilitation program, post-surgery pre-rehabilitation and during rehabilitation complications and pre-discharge physical and ward activites. In this study, more women were hypertensive than men (p=0.002) whereas more men were smokers than women (p=0.014). More women were diabetic (53%) compared with 32% of men, and more men had dyslipidemia, previous MI, CHF and revascularization procedures, however, these were not statistically significant. The number of coronary vessels involved and bypassed and the medications taken were comparable between the two groups. There was no significant difference between men and women as to age, mean number of days from surgery to admission to the CCReP, post-surgery pre-rehabilitation and during rehabilitation complications and pre-discharge physical and ward activities.
