运动试验已广泛应用于冠心病诊断和了解心血管功能状况。临床医师常以运动耐量作为评估运动试验是否达到足量,忽视了其对冠心病诊断的准确性。本研究采用单独增量法(METS),首次评估了运动耐量本身在预示冠心病及其病变程度中的意义。 临床资料和方法 选择800例疑似冠心病者,均经运动试验和冠脉造影术,并具有临床症状、血脂、ST段、峰值心率、冠脉阻塞情况等十项参数变化的完整资料。ST段
Exercise tests have been widely used in the diagnosis of coronary heart disease and understanding of cardiovascular function. Clinicians often exercise capacity as an assessment of exercise tests to achieve full, ignoring the accuracy of its diagnosis of coronary heart disease. This study used a single incremental method (METS), for the first time to assess the significance of exercise tolerance in predicting coronary heart disease and its extent of disease. Clinical data and methods Select 800 cases of suspected coronary heart disease, both by exercise test and coronary angiography, and clinical symptoms, blood lipids, ST segment, peak heart rate, coronary occlusion and other ten parameters of the complete information. ST segment
