The purposes of this study were to determine the trend in stroke recurrence over time and the effect of the prestroke blood pressure and management of hypertension on stroke recurrence in 1,680 incidence cases of stroke in residents of Rochester, Minnesota. Recurrent, primarily ischemic, stroke occurred in 267 cases. Stroke recurrence rates did not change during the 30-year period 1950-1979, in contrast to the decline in initial stroke incidence rates during this time. The overall stroke recurrence rates were less than 5%/yr, with cumulative rates of 5.7%, 19.3%, and 28.8% at 1, 5, and 10 years, respectively. Neither level of blood pressure before the first stroke nor management of hypertension had any apparent effect on stroke recurrence rates throughout the follow-up.
本研究的目的是确定明尼苏达州罗切斯特市居民中1680例首次发生中风病例的中风复发随时间变化的趋势，以及中风前血压和高血压管理对中风复发的影响。267例出现复发性中风，主要为缺血性中风。与这段时间内首次中风发病率的下降相反，1950年至1979年的30年间中风复发率没有变化。总体中风复发率低于每年5%，1年、5年和10年的累积复发率分别为5.7%、19.3%和28.8%。在整个随访期间，首次中风前的血压水平和高血压管理对中风复发率均无明显影响。
