目的 探讨老年急性下壁心肌梗塞（ＡＩＭＩ）合并房室传导阻滞（ＡＶＢ）的临床意义及预后。方法 对１３６例老年急性心肌梗塞（ＡＭＩ）中的４５例ＡＩＭＩ进行临床分析。结果 老年 ＡＩＭＩ合并ＡＶＢ发生率显著高于前壁组（Ｐ＜０．００１），老年ＡＩＭＩ合并ＡＶＢ组肌酸磷酸激酶（ＣＰＫ）峰值（１４０７±８１０Ｕ／Ｌ）明显高于ＡＩＭＩ不合并ＡＶＢ组（８０２±２２４Ｕ／Ｌ），Ｐ＜０．０１，两组在死亡率、心源性休克、心律失常和心衰发生率方面无显著性差异。老年ＡＩＭＩ并发胸前导联ＳＴ段压低易发生左心衰竭，死亡率高。结论 老年ＡＩＭＩ伴ＡＶＢ，或入院时伴胸前导联ＳＴ段压低，应引起重视。
Objective To investigate the clinical significance and prognosis of acute inferior myocardial infarction (AIMI) combined with atrioventricular block (AVB). Methods Clinical analysis of 45 AIMI cases in 136 elderly patients with acute myocardial infarction (AMI) was performed. Results The incidence of AIMI complicated with AVB in the elderly group was significantly higher than that in the anterior wall group (P <0.001). The peak value of creatine phosphokinase (CPK) in the AIMI with AVB group (1407 ± 810U / L) was significantly higher than that in the AIMI group without AVB 802 ± 224U / L), P <0.01. There was no significant difference between the two groups in the incidence of mortality, cardiogenic shock, arrhythmia and heart failure. Elderly AIMI complicated with chest lead ST-segment depression prone to left heart failure, high mortality. Conclusion The elderly AIMI with AVB, or ST-segment depression with chest lead at admission, should pay attention.
