20世纪60年代中期，美国的冠心病死亡率突然下降，在接下来的10年里，所有四个主要的性别种族群体都经历了几乎相同的下降率。然而，从20世纪70年代中期开始，黑人和白人的趋势开始出现分歧，黑人的年度比率下降速度放缓。最近公布的死亡率数据一直延续到1991年，并利用1990年人口普查对1980年代的分母估计数进行了修正，这表明在整个十年中这一趋势呈惊人的线性。1989年，自冠心病这一类别被记录在生命统计数据中以来，黑人男性的年龄调整死亡率首次超过白人。由于男子之间的不同趋势，仅1991年就有4 000多名黑人死亡。在女性中，在这一时期开始时，黑人的冠心病死亡率较高，平均每年下降的百分比仅为白人的三分之二。结果，黑人和白人之间的绝对死亡率差距从19%稳步上升到33%（1980年至1991年）。这项研究表明，导致冠心病下降的因素在过去十年中并没有对所有人口群体产生同等影响。
An abrupt downturn in mortality rates from coronary heart disease occurred in the United States in the mid-1960s, and for the next decade all four major sex-race groups experienced virtually identical rates of decline. Beginning around the mid-1970s, however, trends for blacks and whites began to diverge, with a deceleration in the annual fall in rates for blacks. The recent release of mortality data extending through 1991, with correction of the denominator estimates in the 1980s using the 1990 census, demonstrate a striking linearity of this trend over the entire decade. In 1989, for the first time since the category of coronary heart disease has been recorded in vital statistics, the age-adjusted death rate for it among black men exceeded that of whites. As a result of the divergent trends among men, an excess of 4,000 deaths of blacks were recorded in 1991 alone. Among women, coronary heart disease mortality was higher among blacks at the beginning of this period, and the average annual percent decline was only two-thirds that of whites. As a result, the absolute mortality gap between blacks and whites steadily increased from 19 to 33 percent (1980 to 1991). This study indicates that the factors that have led to the decline in coronary heart disease have not influenced all demographic groups equally over the last decade.
