During 1977-8 we measured blood pressure in 561 old people (83% of those aged 85 or more living in Tampere) and analysed their five year survival according to their blood pressure group. The subjects were divided into six groups on the basis of their blood pressures (from less than 120 to greater than 200 mm Hg systolic, from less than 70 to greater than 110 diastolic). The greatest mortality was observed in those in the lowest systolic and lowest diastolic groups. Mortality was least in subjects with systolic pressures of 160 mm Hg or more and diastolic pressures of 90 mm Hg or more. The most essential finding in this series of the very old was an increased mortality in the lowest blood pressure groups.
1977年至1978年间，我们对561名老年人（占坦佩雷85岁及以上老人的83%）进行了血压测量，并根据他们的血压分组分析了其五年生存率。根据血压（收缩压从低于120毫米汞柱到高于200毫米汞柱，舒张压从低于70毫米汞柱到高于110毫米汞柱），将研究对象分为六组。收缩压和舒张压最低组的死亡率最高。收缩压为160毫米汞柱及以上且舒张压为90毫米汞柱及以上的受试者死亡率最低。在这组高龄人群中，最主要的发现是血压最低组的死亡率增加。
