In 1979, a community-wide hospital surveillance system was established in Monroe County, New York (population 702,000), to investigate the continuing contribution of uncontrolled high blood pressure (HBP) to the occurrence of stroke. This paper reports findings among 200 consecutive strokes in persons under 71 years of age. Average age was 58. There was a prestroke history of HBP in 129 (65 per cent) cases. Two-thirds of the 129 had other predisposing conditions (heart disease, diabetes, previous cerebrovascular accident) and 95 per cent had one or more other cardiovascular risk factors (smoking, elevated cholesterol, obesity). Over 90 per cent had visited a physician during the year prior to stroke (average of four visits). Elevated pressures (DBP greater than or equal to 95 or SBP greater than or equal to 160) were recorded at half or more of the visits for 45 per cent of the patients; these cases were classified as uncontrolled. Reduction of "unnecessary" strokes in persons under age 71 should be achievable by giving increased attention to those already under medical care for hypertension who have co-existing stroke risk conditions and cardiovascular risk factors.
1979年，纽约门罗县（人口70.2万）建立了一个全县范围的医院监测系统，以调查未控制的高血压（HBP）对中风发生的持续影响。本文报告了71岁以下连续200例中风患者的研究结果。平均年龄为58岁。129例（65%）患者有中风前高血压病史。129例中有三分之二患有其他诱发疾病（心脏病、糖尿病、既往脑血管意外），95%有一个或多个其他心血管危险因素（吸烟、胆固醇升高、肥胖）。超过90%的患者在中风前一年曾就医（平均就诊4次）。45%的患者在一半或更多次就诊时记录到血压升高（舒张压大于或等于95或收缩压大于或等于160）；这些病例被归类为未控制。通过更加关注那些已经因高血压接受医疗护理且同时存在中风风险条件和心血管危险因素的患者，应该可以减少71岁以下人群中“不必要”的中风发生。
