Background
The optimal intensity of blood pressure (BP) control in patients with and without type 2 diabetes mellitus (T2D) remains unclear.
Objectives
We performed a systematic review and meta-analysis of randomized controlled trials comparing intensive versus standard BP control, stratified by T2D status.
Methods
Primary outcomes were all-cause mortality and serious adverse events (SAEs); secondary outcomes included death from cardiovascular causes and occurrence of myocardial infarction (MI) and stroke. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using DerSimonian–Laird random-effects models. Heterogeneity was assessed with the I2 statistic, and leave-one-out sensitivity analyses were conducted for all outcomes.
Results
Six trials comprising 41,210 participants were included. Intensive BP control significantly reduced death from cardiovascular causes (OR 0.72; 95% CI 0.56–0.93), incidence of MI (OR 0.85; 95% CI 0.74–0.97), and stroke (OR 0.78; 95% CI 0.68–0.89). The reduction in all-cause mortality was significant in patients without T2D (OR 0.73; 95% CI 0.59–0.90), but not in those with T2D (OR 0.99; 95% CI 0.85–1.14). Intensive control was associated with a non-significant increase in SAEs overall (OR 1.15; 95% CI 0.90–1.46), with higher estimates in patients with T2D.
Conclusions
Intensive BP control reduces cardiovascular events and mortality in non-diabetic patients. In those with T2D, benefits are attenuated and may be counterbalanced by safety concerns. BP targets should be individualized based on diabetes status and clinical context.
