右束支传导阻滞对急性前壁心梗患者长期预后的影响迄今尚无定论。作者观察932例Q波型前壁心梗患者。将其分为不伴右束文传导阻滞组(754例)和伴有右束支传导阻滞组(178例)。后组左心衰发生率、住院期间和出院后1年心脏病死亡率均高于前组(72％对52％,32％对8％,17％对7％,P均<0.001)。多变量分析表明,右束支传导阻滞是急性前壁心梗患者住院期间死亡率和出院后1年心脏病死亡率增高的独立预报因子。
The influence of right bundle branch block on the long-term prognosis of patients with acute anterior myocardial infarction has not yet been determined. The authors observed 932 patients with Q-wave anterior MI. They were divided into right bundle block (754 cases) and right bundle branch block (178 cases). The incidence of left heart failure, cardiac mortality during hospitalization and 1 year after discharge were higher in the latter group than in the former group (72% versus 52%, 32% vs 8%, 17% vs 7%, P <0.001). Multivariate analysis showed that right bundle branch block was an independent predictor of increased hospital mortality during hospitalization and 1-year post-discharge cardiac disease in patients with acute anterior MI.
