【摘要】 目的 探讨房颤病因中冠心病的发生率.方法 对103例房颤伴或不伴典型或不典型心绞痛患者,临床疑诊为冠心病而行冠脉造影.结果 有1支以上冠脉病变狭窄并≥50%者仅有29例,占28.16%.在冠脉造影正常者与异常者之间作左房内径及左室射血分数(LVEF)比较,两组中左房内径比较无显著差异(P>0.05),而两组间LVEF存在显著差异(P<0.01).结论 房颤病人诊断冠心病应全面分析,减少误诊.另外冠心病房颤发生的病理基础可能更多为左心室功能不全.更多还原

【Abstract】 objective This study was discussed the occurrence rate coronary heart disease (CHD) in atrial fibrillation patients. Method There were 103 atrial fibrillation patients with or without,typical or not typical angina pectoris to perform coronary arteries angiographies,and to determine CHD. Results The result was shown that the coronary arteries in 29 cases(28. 16%) were narrowed more than 50% with one or more than one branches. The cases were compared between left atrial diameter and left ventricular ejection fraction (LVEF) in normal and abnormal angiography groups. Compared left atrial diameter both groups was not significant difference(P>0. 05) ,but LVEF in two groups was significant difference (P<0. 01). Conclusion: Atrial fibrillation diagnosed CHD should be analysed well to reduce misdiagnosis. The pathological base of atrial fibrillation in CHD may be left ventricular dysfunction.更多还原
