The incidence of acute myocardial infarction (AMI) among urban blacks appears to be considerably less than that among whites. To evaluate this, all AMIs among Newark, NJ, residents in 1973 were evaluated, using the 1970 census for calculating age, race, and sex-specific rates. Death certificates of patients dead on arrival (DOA) from coronary heart disease (total 517) were also evaluated. Two hundred seventy-three AMIs were documented. Although crude rates per 100,000 population were higher for whites than for blacks, age-specific rates by decades from 20 to 80 revealed no differences. Coronary DOA rates were consistently higher among blacks than among whites, reaching approximately a 21 ratio in the older decades. The apparent rarity of AMI among Newark blacks is attributable to their relative youth compared to whites (77% under 40 vs 56%) and a higher out-of-hospital coronary death rate.

城市黑人的急性心肌梗死 (AMI) 发生率似乎比白人低得多。为了评估这一点,使用1970年人口普查来计算年龄,种族和性别特定比率,对新泽西州纽瓦克市1973年的所有ami进行了评估。还评估了因冠心病 (总517) 而死亡的患者的死亡证明。记录了二百一十三名非盟特派团。尽管白人每100,000人口的粗比率高于黑人,但从20到80的数十年的特定年龄比率没有差异。黑人的冠状动脉DOA率始终高于白人,在过去的几十年中,这一比例约为21。纽瓦克黑人中AMI的明显稀有性归因于他们与白人相比相对年轻 (40岁以下的77% 比56% 岁) 和较高的院外冠状动脉死亡率。
