AUTHORS ' CONCLUSIONS At the present time there is insufficient evidence to know whether a higher BP target ( less than150 to 160/95 to 105 mmHg ) or a lower BP target ( less than 140/90 mmHg ) is better for older adults with high BP .
BACKGROUND Eight out of 10 major antihypertensive trials in older adults attempted to achieve a target systolic blood pressure ( BP ) less than 160 mmHg .
Collectively these trials demonstrated benefit for treatment , as compared to no treatment , for an older adult with BP greater than 160 mmHg .
However an even lower BP target of less than 140 mmHg is commonly applied to all age groups .
At the present time it is not known whether a lower or higher BP target is associated with better cardiovascular outcomes in older adults .

Treatment of hypertension in patients 80 years of age or older.
BACKGROUND Whether the treatment of patients with hypertension who are 80 years of age or older is beneficial is unclear . It has been suggested that antihypertensive therapy may reduce the risk of stroke , despite possibly increasing the risk of death . METHODS We r and omly assigned 3845 patients from Europe , China , Australasia , and Tunisia who were 80 years of age or older and had a sustained systolic blood pressure of 160 mm Hg or more to receive either the diuretic indapamide ( sustained release , 1.5 mg ) or matching placebo .  The angiotensin-converting-enzyme inhibitor perindopril ( 2 or 4 mg ) , or matching placebo , was added if necessary to achieve the target blood pressure of 150/80 mm Hg . The primary end point was fatal or nonfatal stroke . RESULTS The active-treatment group ( 1933 patients ) and the placebo group ( 1912 patients ) were well matched ( mean age , 83.6 years ; mean blood pressure while sitting , 173.0/90.8 mm Hg ) ; 11.8 % had a history of cardiovascular disease . Median follow-up was 1.8 years . At 2 years , the mean blood pressure while sitting was 15.0/6.1 mm Hg lower in the active-treatment group than in the placebo group . In an intention-to-treat analysis , active treatment was associated with a 30 % reduction in the rate of fatal or nonfatal stroke ( 95 % confidence interval [ CI ] , -1 to 51 ; P=0.06 ) , a 39 % reduction in the rate of death from stroke ( 95 % CI , 1 to 62 ; P=0.05 ) , a 21 % reduction in the rate of death from any cause ( 95 % CI , 4 to 35 ; P=0.02 ) , a 23 % reduction in the rate of death from cardiovascular causes ( 95 % CI , -1 to 40 ; P=0.06 ) , and a 64 % reduction in the rate of heart failure ( 95 % CI , 42 to 78 ; P<0.001 ) . Fewer serious adverse events were reported in the active-treatment group ( 358 , vs. 448 in the placebo group ; P=0.001 ) . CONCLUSIONS The results provide evidence that antihypertensive treatment with indapamide ( sustained release ) , with or without perindopril , in persons 80 years of age or older is beneficial .

However , the 95 % confidence intervals of these outcomes suggest the lower BP target is probably not worse , and might offer a clinical ly important benefit .
