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 .
Practitioner's trial on the efficacy of antihypertensive treatment in elderly patients with hypertension II (PATE-hypertension II study) in Japan.
AIM Reduction of elevated blood pressure ( BP ) has been an important treatment goal in elderly hypertensive patients . However , it has been reported that an excessive reduction of systolic BP to less than 120mmHg might be harmful in such patients . We investigated whether this was the case in a study which assessed long-term antihypertensive efficacy , tolerability and impact on cardiovascular/cerebrovascular ( CV ) morbidity/mortality in a large cohort of Japanese patients . METHODS This study was performed at general practitioners ' offices nationwide with a target sample size of 1500 patients . Hypertensive patients aged 60years or more who achieved successful BP control with c and esartan monotherapy , and who tolerated the treatment for at least 8weeks , were enrolled into the study and followed for 3years . RESULTS BP was maintained below the target level of 140/90mmHg over the 3-year period . The incidence of CV events during the study period was 20.4/1000person-years . Investigation of the relationship between BP and the incidence of CV events revealed that patients with higher BP generally had a higher incidence of events . However , very elderly patients ( ≥75years ) with a systolic BP ( SBP ) of less than 120mmHg also had a higher incidence of CV events compared with those with an SBP of 120 - 139mmHg . CONCLUSION This study demonstrated that treatment with c and esartan maintained long-term control of BP in elderly hypertensive patients without serious adverse events . CV events demonstrated a J-curve relationship with SBP in patients aged 75years or older , which suggests that excessive BP reductions might be harmful for very elderly patients
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 .
