目的探讨临床拟诊冠心病冠状动脉造影阴性患者的临床特点。方法对180例冠状动脉造影阴性患者的临床资料进行回顾性分析。结果无典型胸痛者占64.44%;有家族史、吸烟史者较少(分别为19.44%和22.22%);临床检验结果大多正常;临床合并疾病较多,前3位分别为原发性高血压、高脂血症和心律失常。心电图STT改变占54.44%,但缺乏特征性,冠状动脉有23.33%(42/180)不完全正常,最后诊断以原发性高血压居多,心律失常次之,诊断为冠心病者仍占一定的比例。结论心电图检查虽然简便、安全,但诊断冠心病有一定局限性,明确诊断应行冠状动脉造影。
Objective To investigate the clinical features of clinically diagnosed coronary heart disease patients with negative coronary angiography. Methods The clinical data of 180 patients with negative coronary angiography were analyzed retrospectively. Results No typical chest pain accounted for 64.44%; family history, smoking history were less (19.44% and 22.22%, respectively); clinical test results were mostly normal; clinical co-morbidity more, the first three were essential hypertension , Hyperlipidemia and arrhythmia. ECG STT changes accounted for 54.44%, but the lack of characteristic coronary arteries were 23.33% (42/180) is not fully normal, the final diagnosis of hypertension, followed by arrhythmia, diagnosis of coronary heart disease still accounted for some proportion. Conclusions Although ECG is simple and safe, the diagnosis of coronary heart disease has its own limitations. A definite diagnosis should be given to coronary angiography.
