目的研究平板运动试验过程中诱发变异性心绞痛的临床意义。方法对比6例在平板运动试验中发生变异性心绞痛患者冠脉造影检查结果。结果 6例运动中发生变异性心绞痛患者心电图有定位改变,其中前壁ST-T改变4例,下壁ST-T改变2例,均发生典型心绞痛症状,其中一例发生心源性休克。行冠脉造影检查显示4例前降支病变,2例右冠脉病变。结论平板运动试验是一种变异性心绞痛重要的无创检查手段。
Objective To study the clinical significance of induced angina pectoris during treadmill exercise test. Methods The results of coronary angiography in 6 patients with variant angina pectoris under treadmill exercise test were compared. Results The electrocardiogram of 6 cases of patients with variant angina pectoris had locating changes. Among them, 4 cases of ST-T changes in the anterior wall and 2 cases of ST-T changes in the inferior wall showed typical symptoms of angina pectoris, of which 1 case had cardiogenic shock. Line coronary angiography showed 4 cases of anterior descending artery lesions, 2 cases of right coronary artery lesions. Conclusion The treadmill test is an important noninvasive means of detecting variant angina.
