The purpose of this study is to prediet the morbidity and mortality by cardiovascular disease in the obese woman using ST segment depression during treadmill exercise. Subjects were 37 women who were 28-43 years old, and they were classified into three groups by BMI: Normal, Overweight, Obesity, HR, BP, rm dot V O_(２)max and ST segment level were measured during exercise with Bruce treadmill protocol. As a result, HR and SBP were increased in proportion to the exercise intensity. In the submaximal exercise. HR and SBP of Obesity were higher than Normal. But at the maximal stage, the exercise duration, reached intensity and rm dot V O_(２) of Obesity were significantly lower than Normal (p<.05). ST segment and ST/HR slop were depressed in proportion to the exercise intensity. During exercise, ST segment and ST/HR slop of Obesity were lower than Normal. Especially the maximal ST depression of Obesity was -125uN that was the abnormal values indicating ischemic prognostics. When ST/HR slop was compared with ST segment, the ischemic symptoms were apt to early diagnose in ST/HR slop. Duke treadmill score (DTS) was significantly (p<.05) lower in Obesity than Normal, but annual cardiovascular mortality (CVM) was significantly (p<.05) higher in Obesity than Normal. These results indicated that the morbidity and annual mortality by cardiovascular disease were increased in the obese women. |
