The primary contribution to increased incidence rates for ischemic stroke in Rochester, Minnesota, for the 1980 to 1984 time period in the age groups from 55 to 84 years was from those persons in the population with ischemic heart disease. The rate and pattern of the decline in incidence rates of ischemic stroke in hypertensive individuals and in nonhypertensive individuals were quite similar, showing no demonstrable population effect of antihypertensive medication. These observations emphasize that there must be some, as yet unidentified, factor that is important in the decline of stroke incidence.
在明尼苏达州罗切斯特市，1980年至1984年期间，55至84岁年龄组缺血性中风发病率上升的主要原因是患有缺血性心脏病的人群。高血压个体和非高血压个体中缺血性中风发病率下降的速率和模式非常相似，未显示出抗高血压药物对总体人群有明显影响。这些观察结果强调，一定存在某种尚未明确的因素，对中风发病率的下降至关重要。
