[Stroke, coronary heart disease and all cause mortalities analyses for hypertension]

The mortalities of 870 hypertensives, aged 35 and over, during 1986-1988 in a community were analysed, and SMRs (standardised mortality ratio) were calculated according to the data of population and mortality in the community. The results showed that, among the hypertensives, all cause death and stroke death were related to the level of systolic blood pressure beside the age. SMR analyses indicated that stroke death level in the group with hypertension was significantly higher than general population, and the extra death for all cause death, stroke and CHD (coronary heart disease) in the hypertensive group of less than 60 years old were particularly higher. However the SMR in the group of 70 or over were close to 100 or even lower than 100. It suggested that more consideration should be given to the hypertensives of younger age group (less than 60).
