Strict control [ systolic BP ( SBP ) < 140 mmHg ] was not consistently better than mild control ( SBP < 150 mmHg ) for adults aged ≥65 years .
Mild SBP control benefitted subjects in all age ranges over 65 years .
Conclusions In this review , older adults with hypertension had decreased cardiovascular morbidity and mortality  with antihypertensives compared with no treatment .
Strict control was not consistently better than mild control in older adults .
The current evidence is insufficient to determine the safest , most beneficial hypertension regimen in older adults

Angiotensin II receptor blocker-based therapy in Japanese elderly, high-risk, hypertensive patients.
BACKGROUND It is unknown whether high-dose angiotensin II receptor blocker therapy or angiotensin II receptor blocker + calcium channel blocker combination therapy is better in elderly hypertensive patients with high cardiovascular risk . The objective of the study was to compare the efficacy of these treatments in elderly , high-risk Japanese hypertensive patients . METHODS The OlmeSartan and Calcium Antagonists R and omized ( OSCAR ) study was a multicenter , prospect i ve , r and omized , open-label , blinded-end point study of 1164 hypertensive patients aged 65 to 84 years with type 2 diabetes or cardiovascular disease . Patients with uncontrolled hypertension during treatment with olmesartan 20 mg/d were r and omly assigned to receive 40 mg/d olmesartan ( high-dose angiotensin II receptor blocker ) or a calcium channel blocker + 20 mg/d olmesartan ( angiotensin II receptor blocker + calcium channel blocker ) . The primary end point was a composite of cardiovascular events and noncardiovascular death . RESULTS During a 3-year follow-up , blood pressure was significantly lower in the angiotensin II receptor blocker + calcium channel blocker group than in the high-dose angiotensin II receptor blocker group . Mean blood pressure at 36 months was 135.0/74.3 mm Hg in the high-dose angiotensin II receptor blocker group and 132.6/72.6 mm Hg in the angiotensin II receptor blocker + calcium channel blocker group . More primary end points occurred in the high-dose angiotensin II receptor blocker group than in the angiotensin II receptor blocker + calcium channel blocker group ( 58 vs 48 events , hazard ratio [ HR ] , 1.31 , 95 % confidence interval , 0.89 - 1.92 ; P=.17 ) . In patients with cardiovascular disease at baseline , more primary events occurred in the high-dose angiotensin II receptor blocker group ( HR , 1.63 , P=.03 ) ; in contrast , fewer events were observed in the subgroup without cardiovascular disease ( HR , 0.52 , P=.14 ) . This treatment-by-subgroup interaction was significant ( P=.02 ) . CONCLUSION The angiotensin II receptor blocker and calcium channel blocker combination lowered blood pressure more than the high-dose angiotensin II receptor blocker and reduced the incidence of primary end points more than the high-dose angiotensin II receptor blocker in patients with cardiovascular disease . The addition of a second antihypertensive agent is more effective at lowering blood pressure than simply doubling the dose of an existing agent
