静息心电图正常的老年冠心病患者临床特点分析

目的：探讨静息心电图正常的老年冠心病患者的临床特征。方法：对46例心电图正常的老年冠心病患者冠状动脉造影结果及其危险因素资料进行回顾性分析。结果：46例患者中，冠状动脉单支病变者为18例（39.1％），多支病变者28例（60.9％）；前降支病变32例，右冠状动脉病变22例，左回旋支病变16例，左主干病变2例；与单支病变组比较，多支病变组合并糖尿病（33.3％比75.0％）及慢性肾病（22.2％比53.6％）比例相对较高，有统计学差异（P均＜0.05）。结论：静息心电图正常的老年冠心病患者冠脉多支病变较常见，且合并糖尿病及慢性肾病者比例较高。

Clinical characteristic of aged patients with coronary heart disease and normal resting electrocardiogram

Objective：To explore clinical features of aged patients with coronary heart disease （CHD）and normal resting electrocardiogram （ECG）.Methods：The data of coronary angiography results and its risk factors were retrospectively analyzed in 46 aged CHD patients with normal resting ECG.Results：In the 46 patients,there were 18 cases （39.1%）with single-vessel coronary disease and 28 cases （60.9%）with multi-vessel coronary disease;32 cases with left anterior descending artery disease,22 cases with right coronary artery disease,16 cases with left circumflex coronary artery disease and two cases with left main disease.Compared with single vessel coronary disease group, there were significant rise in percentage of patients complicated with diabetes mellitus （33.3% vs.75.0%）and chronic kidney disease （22.2% vs.53.6%）in multi-vessel coronary disease group,P 〈0.05 both.Conclusion： Multi-vessel coronary disease is frequent,and percentages of patients complicated with diabetes mellitus and chronic kidney disease are higher in aged patients with coronary heart disease and normal resting electrocardiogram.
