A long-term decline in death rates from cerebrovascular diseases in the United States accelerated in 1969, with a further increase in the rate of decline after 1972. This break in the pattern of the mortality curve for stroke was observed in all 4 major sex-color groups, and affected all age groups in which a significant number of stroke deaths occur. The decline for non-whites was relatively and absolutely greater than for the comparable white sex. If the 1960 rates had persisted in 1975, 87,600 more lives would have been lost to cerebrovascular diseases. Although there are no data documenting a declining prevalence of hypertension in the population, detection, treatment and control of hypertension have improved markedly over recent years. A concomitant decrease in the severity of epidemic respiratory infection may have contributed to the improvement in recorded death rates from stroke. Mortality from all major cardiovascular diseases has demonstrated a parallel downward trend. Continued emphasis on public health efforts to detect and treat hypertension and other known cardiovascular risk factors can be expected to result in further improvement in cardiovascular mortality.
美国脑血管疾病死亡率的长期下降在1969年加速，1972年后下降速度进一步加快。这种中风死亡率曲线模式的变化在所有4个主要性别-肤色群体中均有观察到，并影响了所有有大量中风死亡发生的年龄组。非白人的下降幅度相对和绝对都大于可比的白人性别。如果1960年的死亡率在1975年持续存在，那么因脑血管疾病死亡的人数将会多87,600人。尽管没有数据记录人群中高血压患病率的下降情况，但近年来高血压的检测、治疗和控制有了显著改善。流行性呼吸道感染严重程度的相应降低可能有助于中风记录死亡率的改善。所有主要心血管疾病的死亡率都呈现出平行的下降趋势。持续强调公共卫生工作以检测和治疗高血压及其他已知的心血管危险因素，有望进一步改善心血管疾病死亡率。
