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 .
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 .
OBJECTIVES To assess the effects of a higher ( less than 150 to 160/95 to 105 mmHg ) BP target compared to the lower BP target of less than 140/90 mmHg in hypertensive adults 65 years of age or older .
Lower target blood pressures are safe and effective for the prevention of recurrent stroke: the PROGRESS trial
Objective To explore the likely optimum blood pressure ( BP ) level for patients with a history of cerebrovascular disease . Methods The Perindopril Protection Against Recurrent Stroke Study ( PROGRESS ) was a r and omized , placebo-controlled trial that established the beneficial effects of BP lowering in 6105 patients with cerebrovascular disease . The present study comprises two series of post hoc analyses . The first was design ed to investigate the effects of r and omized treatment on recurrent stroke by baseline BP levels , and the second was a corresponding observational analysis investigating the association between achieved follow-up BP levels and recurrent stroke risk . Results Analyses of the r and omized treatment comparisons showed that BP lowering with combination therapy produced similar risk reductions in each of four subgroups defined by baseline BP of less than 120 , 120–139 , 140–159 , and 160 mmHg or greater ( P homogeneity = 0.5 ) . The effects of single-drug therapy were also comparable across these subgroups ( P homogeneity = 0.2 ) , but consistently greater benefits were observed with combination compared to single-drug therapy . The analyses of achieved follow-up BP showed that the lowest risk of recurrence was among the one-quarter of participants with the lowest follow-up BP levels ( median 112/72 mmHg ) , and that risks rose progressively with higher follow-up BP levels . Minor side-effects were progressively more common at lower BP levels ( P homogeneity = 0.04 ) , but there was no excess of serious complications ( all P homogeneity > 0.2 ) . Conclusion These analyses provide no evidence of a J-curve relationship between BP level and stroke risk among patients with cerebrovascular disease , and identify no patient group among whom more intensive BP lowering would not be expected to produce greater risk reductions
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 .
