Abstract
The relationship between exercise ST depression and a set of coronary risk factors was evaluated in 285 asymptomatic men, aged 35–59 years. Only subjects with a normal resting ECG and a systolic blood pressure below 180 mm Hg were included. The following risk factors were considered: age, body mass index, blood pressure, serum lipids and uric acid, basal and after load blood glucose, physical activity and smoking. Computer analysis of CB5 lead was utilized to study the magnitude of ST responses to a maximal treadmill test. The following ST parameters were evaluated: ST depression at R + 80 ms point (ST2), mean ST depression (STmean) and ST time-voltage integral (STarea). Age, serum cholesterol, blood glucose after load and, to a lesser degree, physical activity have proved to be the risk factors best correlated with exercise ST depression. The multiple regression analysis showed that the global risk factors evaluation explained up to 17% of ST2 variance, 12% of STmean 11% of STarea In conclusion, our data show that the wide scatter of exercise ST displacement in asymptomatic men is poorly explained by the variability of coronary risk factors.
