近年通过对运动试验受检者的长期随访以及运动试验与冠状动脉(下略称冠咏)造影对比研究,证明运动试验 ST 段缺血型压低(水平型或下垂型压低:双倍二阶梯运动试验压低≥0.5毫米,活动平板运动试验压低≥1.0毫米)与冠脉狭窄正相关,且对冠心病的予后亦有一定的预测价值。本文就ST 段改变与予后的有关资料简要作一综述。Mattingly 对双倍二阶梯运动试验(下略称双倍试验)ST 段压低0.5毫米以上的患者,经随访10年结果:38%发生心肌梗塞,因冠心病死亡者
In recent years, through the long-term follow-up of exercise test subjects as well as comparative study of exercise test and coronary artery (hereinafter referred to as crown Yong) angiography, ST segment ischemic depression (exercise-induced type of depression or ptosis: Depression ≥ 0.5 mm, treadmill exercise test pressure ≥ 1.0 mm) is positively correlated with coronary stenosis, and the prognosis of coronary heart disease also has some predictive value. This article reviews the ST segment changes and related information briefly reviewed. Mattingly A 10-year follow-up of patients with ST-segment depression 0.5% or more in the Double-Step Exercise Test (abbreviated double trial) results in 38% of patients with myocardial infarction and those who died of coronary heart disease
