选择性冠状动脉造影在冠心病中的诊断价值

Diagnostic Value of Selective Coronary Arteriography on Patients with Coronary Artery Disease:Analysis of 46 Cases

目的 探讨冠状动脉狭窄病变的分布特点及冠状动脉造影在冠心病中的诊断价值。方法 采用Judkins法行选择性左、右冠状动脉造影并结合临床分析 4 6例冠脉造影结果。结果 冠脉狭窄的好发部位为前降支 ,其次为右冠及回旋支 ;心肌梗塞、心绞痛冠脉造影的阳性率高 ,而临床仅以心律失常为主要表现 ,尤其是老年房颤患者阳性率低。结论 心电图无病理性Q波 ,仅凭ST -T改变 ,对高心病患者拟诊合并冠心病应慎重。临床无其它冠心病危险因素 ,单以不典型胸痛为表现 。

Objective:To investigate distribution of the coronary artery stenoses and the value of selective coronary arteriography(SCA) on clinical diagnosis of coronary artery disease(CAD).Methods:Judkins technique was used to analyze the SCA of 46 cases with coronary artery disease.Results: Left anterior descend(LAD) was the most prevailing place of CAD,and the second place was the right coronary artery(RCA) or the left circumflex(LCX).The patients with myocardial infartion and angina pectoris showed a higher positive rate of SCA than those patients with arrhythmia,particularly with atrial fibrillation.Conclusion:When only ST T changes but no pathic Q wave was observed in ECG,diagnosis of patients with CAD and hypertensive heart disease must be precautious.
