不典型胸痛患者冠状动脉造影结果分析

Analysis of the results of coronary angiography in patients with atypical chest pain

目的 分析不典型胸痛患者的冠状动脉造影结果 ,探讨冠心病诊断的有关问题。方法 冠状动脉造影采用Judkins法 ,血管内径狭窄≥ 5 0 %时 ,诊断为冠心病。结果 5 0例患者仅有 2例造影证实有冠状动脉狭窄 ,其中 1例前降支狭窄为室性早搏患者 ,1例为对角支狭窄 ,无心律失常表现。其他 4 8例 (96 % )患者均未发现冠状动脉病变 ,其中 2例因造影剂排空大于 3个心动周期而诊断为X—综合征。结论 不典型胸痛患者如果经济困难应首选无创性检查 。

Objective To explore the dignosis of coronary heart disease through the analysis of the results of coronary angiography in patients with atypical chest pain.Methods Coronary angiography was performed with Judkins technique.If the narrowing of vessel≥50%,the patient was diagnosed as coronary heart disease.Results Only 2 of the 50 patients were confirmed with the narrowing of coronary artery.Of these,one patient with stenosis at left anterior descending coronary artery had ventricular premature beats,the other one with stenosis at opposite angles branch had no arrhythmias.In other 48 patients,coronary artery lesions were not found.Of these,2 patients were diagnosed as X syndrome because the empty time of contrast medium was more than 3 cardiac cycle.Conclusion If patients with atypical chest pain have financial problems,the non invasive methods should be firstly chosen.Coronary angiography would be performed to the cases with positive findings.
