Mortality rates and antihypertensive therapy in extreme old age.
The impact of hypertension on survival in extremely old age has shown different features in different studies, with equal or lower mortality rates in hypertensive patients and lower reduction of risk in treated patients. In a population (n=414) of old community dwellers (mean age 88.4 years) the prevalence of hypertension was 52.2%. Hypertensive patients presented a lower mortality rate (14.2 per 100 person-years) as compared to the general population (15.4) and to non-hypertensives (16.6). Hypertensives were divided into four groups according to treatment. Best survival was shown by patients under treatment with antihypertensives alone (9.8) or in association with diuretics (9.9), and worst survival by patients under a diuretic-based treatment (25.1). These data were confirmed by multivariate analysis. The better survival of hypertensive very old people could be related to the use of a proper pharmacotherapy.
