ABSTRACT
Incidence of coronary artery disease (CAD) increases sharply after menopause in women. Rate pressure product (RPP) is a major determinant of cardiac oxygen consumption. It is an important indicator of ventricular function. RPP varies with exercise. The peak rate pressure product (PRPP) which gives an accurate reflection of the myocardial oxygen demand and myocardial workload is the RPP at peak of exercise. The higher the PRPP, the more will be myocardial oxygen consumption (MVO2). The ability to reach higher PRPP is associated with more adequate coronary perfusion. Thus the low value of PRPP suggests significant compromise of coronary perfusion and decreased left ventricular function. In the present study effect of exercise on RPP of pre and postmenopausal women with CAD was compared. The percentage increase in RPP was significantly more in postmenopausal women with CAD (62%) as compared to premenopausal women with CAD (54%) indicating more compromised coronary perfusion in postmenopausal women.
