Long-term bariatric surgery (≥5 years) significantly reduces the incidence of macrovascular complications, cardiovascular events, and myocardial infarction in severely obese patients with type 2 diabetes compared to conventional medical therapy.
For severely obese individuals with Type 2 Diabetes, bariatric surgery offers significant long-term protection against heart attacks, strokes, and other cardiovascular complications compared to standard medical treatment alone. This benefit persists for at least five years post-surgery. While surgery is a major intervention, the data supports its use for reducing major cardiovascular risks in this specific population.
Patients in the bariatric surgery group as compared to the conventional treatment group had lower incidence of macrovascular complications (RR = 0.43, 95%CI = 0.27~0.70), cardiovascular events (CVEs) (HR = 0.52, 95%CI = 0.39~0.71), and myocardial infarction (MI) (RR = 0.40, 95%CI = 0.26~0.61).
Why this rating
Meta-analysis of 4 RCTs and 6 cohort studies with long-term follow-up (5-20 years), though heterogeneity was high in some metrics.
