Data from multiple sources indicate that the death rate for blacks is higher than for the general population-in part because of higher mortality from cardiovascular causes. The Cardiovascular Mortality Survey, carried out in Los Angeles, indicates that the combined effects of increased mortality from high blood pressure and related causes (e.g. stroke, cerebrovascular disease), together with an ischemic heart disease mortality rate that is only a little below the mean, accounts for the overall excess mortality rates in blacks. In addition, black patients have been shown to have higher risk profiles compared with the study mean in a large study of beta-blocker therapy, and a definite treatment effect was demonstrated. Further prospective studies of natural history and response to therapy are indicated for appropriately selected patient groups.
来自多个来源的数据表明，黑人的死亡率高于总人口——部分原因是心血管疾病导致的死亡率更高。在洛杉矶进行的心血管死亡率调查表明，高血压及相关病因（如中风、脑血管疾病）导致的死亡率上升，再加上缺血性心脏病死亡率略低于平均水平，共同导致了黑人总体死亡率偏高。此外，在一项关于β受体阻滞剂治疗的大型研究中，与研究均值相比，黑人患者显示出更高的风险特征，并且证实了明确的治疗效果。对于适当选择的患者群体，需要进一步开展关于自然病史和治疗反应的前瞻性研究。
