We have studied clinical and ECG stress features of 119 patients with left main disease and 113 matched patients with three vessels coronary disease. Clinical features and ECG stress test do not differentiate the two groups as a whole. Exercise time duration was shorter, ST criteria were more positive, and peak heart rate was lower in the subgroups of patients with left main and involvement of a right dominant coronary artery. However due to a large overlap these criteria do not seem to be clinically useful. In conclusion, in an individual patient angina and stress ECG criteria do not differentiate the patients with left main from those with three vessels coronary artery disease.
我们研究了119例左主干病变患者和113例匹配的三支冠状动脉病变患者的临床及心电图负荷特征。临床特征和心电图负荷试验并不能整体区分这两组患者。在左主干病变且累及右优势冠状动脉的亚组患者中,运动持续时间较短,ST段标准更呈阳性,且峰值心率较低。然而,由于存在大量重叠,这些标准似乎在临床上并无用处。总之,对于个体患者,心绞痛和负荷心电图标准并不能区分左主干病变患者和三支冠状动脉病变患者。
