一、无症状心肌缺血中年人群中不管运动是否引起心肌缺血,无症状冠状动脉病的发生率约2.4～4％。就健康人而言,极量运动试验阳性的无症状患者并非都存在冠状动脉病。Froelicher调查1390名空军,发现运动试验阳性者占10％,然导管检查仅证实其中2.5％的患者有明显的冠状动脉病理改变。踏车试验阳性的健康人每年病死率不到1％,但每年心绞痛、心肌梗塞(心梗)等心脏病事件的发生率为5～10％。对照组每年冠状动脉病的发生率
First, asymptomatic myocardial ischemia in middle-aged people regardless of exercise whether caused by myocardial ischemia, asymptomatic coronary artery disease incidence of about 2.4 to 4%. In healthy people, coronary symptoms are not always present in asymptomatic patients who have had maximal exercise tests. Froelicher surveyed 1,390 air forces and found 10% of patients who tested positive for exercise. However, catheterization confirmed that only 2.5% of patients had significant coronary pathological changes. The annual fatality rate of healthy people who treadmill test positive is less than 1%, but the annual incidence of heart disease such as angina pectoris and myocardial infarction (MI) is 5% -10%. The incidence of coronary artery disease in the control group each year
