对1975、1978和1981年期间wozcestez城区16家医院245例急性心肌梗塞住院病人的发病率、院内死亡率和长期幸存率,进一步分为有Q波的MI和无Q波MI进行了社会性调查。经年龄校正的医院发生率(每十万)有初始Q波的MI从1975年153增加到1981年197(P<0.05),而无Q波MI发生率从1975年46例增加到1981年89例(P<0.001)。无Q波MI病人住院期间死亡率的危险性(12.0％)远较Q波MI(25.2％)为低。总的研究以及3期中各期的研究结果也是如此(P<0.05)。然而,对出院时存活的病
The incidence, in-hospital mortality and long-term survival rate of 245 hospitalized acute myocardial infarction patients in 16 hospitals in wozcestez district in 1975, 1978 and 1981 were further divided into those with Q wave MI and without Q wave MI . The age-adjusted hospital incidence (per 100,000) had an initial Q-wave MI increased from 153 in 1975 to 197 in 1981 (P <0.05), whereas the incidence of Q-wave MI increased from 46 in 1975 to 89 in 1981 Cases (P <0.001). The risk of in-hospital mortality without Q-wave MI was significantly lower (12.0%) than with Q-wave MI (25.2%). This is also true for the overall study and the results of the three phases (P <0.05). However, the disease survived on discharge
