在冠心病负荷试验中达到的最大心肌氧耗是某种负荷试验敏感性的决定因素。本研究比较在动脉造影证实的CAD患者中平板和踏车两种运动试验在总体和心肌氧耗以及运动诱导的心肌缺血发生率及严重程度等方面的差别。方法对象为52例无症状的经造影证实的男性CAD患者。左主干CAD、做过冠脉成形术或冠脉旁路手术、左室射血分数明
The maximum myocardial oxygen consumption reached in the coronary heart disease stress test is a determinant of the sensitivity of some stress tests. This study compared the differences in overall and myocardial oxygen consumption and the incidence and severity of exercise-induced myocardial ischemia between treadmill and treadmill exercise test in CAD patients confirmed by arteriography. METHODS: Fifty-two asymptomatic men with CAD were enrolled. Left main CAD, done coronary angioplasty or coronary bypass surgery, left ventricular ejection fraction
