    Abstract:
    Whether the strict control of blood pressure (BP) of patients with hypertension who are aged 85 years or older is beneficial is unclear. The Japan's Benidipine Research on Antihypertensive Effects in the Elderly study is a prospective, observational 3-year study to evaluate the safety and effectiveness of treatment with a calcium channel blocker benidipine in 8897 hypertensive patients aged 65 years or older as a post-marketing surveillance. We examined the relationship between the achieved BP and cardiovascular events (i.e., stroke, myocardial infarction, and heart failure) in a subgroup of 415 patients aged 85 years or older (mean age 88 years). BP decreased significantly from 165 ± 14/84 ± 10 mmHg to 130 ± 11/71 ± 10 mmHg during treatment in patients with a treated systolic BP (SBP) < 140 mmHg (n = 230) and BP decreased significantly from 169 ± 16/86 ± 12 mmHg to 143 ± 13/75 ± 10 mmHg in those with a treated SBP ≥ 140 mmHg (n = 185). There was a nonsignificant trend toward a lower rate of cardiovascular events and higher rate of total death in patients with a treated SBP < 140 mmHg. On-treatment SBP ≥ 160 mmHg is tended to associate with a higher incidence of cardiovascular events. There was no significant difference in the incidence of adverse reactions between the controlled BP group (3.04%) and the less well controlled BP group (3.24%). In conclusion, although this study was not powered for definitive conclusion, there was a nonsignificant trend toward a lower rate of cardiovascular events and higher total death in patients aged 85 years or older with a treated SBP < 140 mmHg.
