摘要
目的探讨平板运动试验诱发ST段抬高对冠心病诊断的临床意义。方法比较平板运动试验中ST段抬高组与ST段压低组患者的冠状动脉造影结果。结果 ST段抬高组与ST段压低组冠状动脉造影结果显示,阳性率、血管狭窄程度以及受累支数均有显著差异(P<0.05)。结论平板运动试验诱发的ST段抬高是冠状动脉严重狭窄或痉挛所致心肌局部严重缺血损伤的标志,是诊断冠心病准确有效的重要指标。
Objective To explore the clinical significance of threadmill exercise test induced ST segment elevation to diagnose coronary heart disease. Methods： Compared the coronary artery contrast results of patients in ST segment elevation group and ST segment lower group in threadmill exercise test. Results： The positive rate ,level of angiostenosis and involvement branch number of coronary artery contrast results of patients in ST segment elevation group and ST segment lower group were different significantly （ P 〈 0.05 ）. Conclusion： Threadmill exercise test induced ST segment elevation was the symbol of cardiac muscle local serious ischemic injury caused by coronary artery severe stricture or spasm, and it was the important index of diagnosing coronary heart disease .
