Abstract :
Beta blockers used for the treatment of hypertension may be associated with increased risk for new-onset diabetes mellitus (DM). A search of Medline, PubMed, and EMBASE was conducted for randomized controlled trials of patients taking β blockers as first-line therapy for hypertension with data on new-onset DM and follow-up for ≥1 year. Twelve studies evaluating 94,492 patients fulfilled the inclusion criteria. Beta-blocker therapy resulted in a 22% increased risk for new-onset DM (relative risk 1.22, 95% confidence interval [CI] 1.12 to 1.33) compared with nondiuretic antihypertensive agents. A higher baseline fasting glucose level (odds ratio [OR] 1.01, 95% CI 1.00 to 1.02, p = 0.004) and greater systolic (OR 1.05, 95% CI 1.05 to 1.08, p = 0.001) and diastolic (OR 1.06, 95% CI 1.01 to 1.10, p = 0.011) blood pressure differences between the 2 treatment modalities were significant univariate predictors of new-onset DM. Multivariate meta-regression analysis showed that a higher baseline body mass index (OR 1.17, 95% CI 1.01 to 1.33, p = 0.034) was a significant predictor of new-onset DM. The risk for DM was greater with atenolol, in the elderly, and in studies in which β blockers were less efficacious antihypertensive agents and increased exponentially with increased duration on β blockers. For the secondary end points, β blockers resulted in a 15% increased risk for stroke, with no benefit for the end point of death or myocardial infarction. In conclusion, β blockers are associated with an increased risk for new-onset DM, with no benefit for the end point of death or myocardial infarction and with a 15% increased risk for stroke compared with other agents. This risk was greater in patients with higher baseline body mass indexes and higher baseline fasting glucose levels and in studies in which β blockers were less efficacious antihypertensive agents compared with other treatments.
