Trial of intensive blood-pressure control in older patients with hypertension
New England Journal of Medicine Oct 13, 2021
Zhang W, Zhang S, Deng Y, et al. - A lower incidence of cardiovascular events in older patients with hypertension was achieved with intensive treatment with a systolic blood-pressure target of 110 to less than 130 mm Hg vs standard treatment with a target of 130 to less than 150 mm Hg.
This is a multicenter, randomized, controlled trial of Chinese patients 60 to 80 years of age with hypertension, who were (n=8511) randomized to a systolic blood-pressure target of 110 to less than 130 mm Hg (intensive treatment) or a target of 130 to less than 150 mm Hg (standard treatment).
A composite of stroke, acute coronary syndrome, acute decompensated heart failure, coronary revascularization, atrial fibrillation, or death from cardiovascular causes, was assessed (primary outcome).
In the intensive- and standard-treatment groups, primary-outcome events occurred in 147 (3.5%) and 196 (4.6%) patients, respectively (hazard ratio, 0.74), during a median follow-up of 3.34 years.
Intensive treatment was favored based on outcomes for most of the individual components of the primary outcome: hazard ratio for stroke was 0.67, acute coronary syndrome 0.67, acute decompensated heart failure 0.27, coronary revascularization 0.69, atrial fibrillation 0.96, and death from cardiovascular causes 0.72.
The two groups had no significant difference in safety and renal outcomes, except that intensive treatment group had a higher incidence of hypotension.
