Blood pressure, left ventricular hypertrophy and diabetes among 179 very old hypertensives from an Italian general population. The CASTEL (Cardiovascular Study in the Elderly).

Hypertension is common in elderly subjects, but old and particularly very old people have usually been excluded from major epidemiological trials. We studied 179 hypertensive subjects aged 80 years or more drawn from elderly people of an Italian town within the context of the CASTEL (Cardiovascular Study in the Elderly). Prevalence of hypertension declined from 66.7% (first visit, first measurement) to 56.3% (last visit, last measurement). Systolic but not diastolic blood pressure was a little higher among very old hyperglycemic hypertensive subjects than in normoglycemic ones, while left ventricular mass was independent of both blood pressure and glucose intolerance.
