Hypotensive therapy in stroke survivors.
Abstract A prospect i ve r and omised controlled trial of hypotensive therapy in 97 hypertensive patients surviving an ischaemic-type stroke was started in 1964 and terminated 4 years later . The patients were under 80 years of age , consecutively admitted to one hospital and the control and treated groups compared well for age , sex , and severity of hypertension . The drugs used were methyldopa , bethanidine or debrisoquine combined with restriction of salt intake , weight reduction , and thiazide diuretics , and the results were analysed with regard to survival and recurrence rates . Hypertension was defined as diastolic if this pressure was 110 mm . Hg or above , and as systolic if this pressure was over 160 mm . Hg with the diastolic below 110 mm . Hg . The mortality-rate at the end of a 2 to 5 year followup was 26 % in the treated group and 46 % in the untreated , and the non-fatal recurrence-rate 14 % in the treated and 23 % in the controls . Good smooth control was essential to success , untreated patients doing better than those whose control was unsatisfactory . In patients aged over 65 treatment of systolic hypertension was of no benefit , although the diastolic hypertensives improved marginally with treatment . As age increased this effect was progressively less apparent but the figures are probably too small to mean anything . In this series significant improvement occurred in treated hypertensive patients who had survived a stroke if they were aged 65 or below , but not if they were older
