Subgroup and per-protocol analysis of the randomized European Trial on Isolated Systolic Hypertension in the Elderly.
BACKGROUND In 1989 , the European Working Party on High Blood Pressure in the Elderly started the double-blind , placebo-controlled , Systolic Hypertension in Europe Trial to test the hypothesis that antihypertensive drug treatment would reduce the incidence of fatal and nonfatal stroke in older patients with isolated systolic hypertension . This report addresses whether the benefit of antihypertensive treatment varied according to sex , previous cardiovascular complications , age , initial blood pressure ( BP ) , and smoking or drinking habits in an intention-to-treat analysis and explores whether the morbidity and mortality results were consistent in a per- protocol analysis . METHODS After stratification for center , sex , and cardiovascular complications , 4695 patients 60 years of age or older with a systolic BP of 160 to 219 mm Hg and diastolic BP less than 95 mm Hg were r and omized . Active treatment consisted of nitrendipine ( 10 - 40 mg/d ) , with the possible addition of enalapril maleate ( 5 - 20 mg/d ) and /or hydrochlorothiazide ( 12.5 - 25 mg/d ) , titrated or combined to reduce the sitting systolic BP by at least 20 mm Hg , to below 150 mm Hg . In the control group , matching placebo tablets were employed similarly . RESULTS In the intention-to-treat analysis , male sex , previous cardiovascular complications , older age , higher systolic BP , and smoking at r and omization were positively and independently correlated with cardiovascular risk . Furthermore , for total ( P = .009 ) and cardiovascular ( P = .09 ) mortality , the benefit of antihypertensive drug treatment weakened with advancing age ; for total mortality ( P = .05 ) , the benefit increased with higher systolic BP at entry , while for fatal and nonfatal stroke ( P = .01 ) , it was most evident in nonsmokers ( 92.5 % of all patients ) . In the per protocol analysis , active treatment reduced total mortality by 24 % ( P = .05 ) , reduced all fatal and nonfatal cardiovascular end points by 32 % ( P<.001 ) , reduced all strokes by 44 % ( P = .004 ) , reduced nonfatal strokes by 48 % ( P = .005 ) , and reduced all cardiac end points , including sudden death , by 26 % ( P = .05 ) . CONCLUSIONS In elderly patients with isolated systolic hypertension , stepwise antihypertensive drug treatment , starting with the dihydropyridine calcium channel blocker nitrendipine , improves prognosis . The per- protocol analysis suggested that treating 1000 patients for 5 years would prevent 24 deaths , 54 major cardiovascular end points , 29 strokes , or 25 cardiac end points . The effects of antihypertensive drug treatment on total and cardiovascular mortality may be attenuated in very old patients
