Key Findings
- Medical weight management (lifestyle + older obesity meds) showed no significant reduction in major adverse cardiovascular events versus usual care.
- Metabolic/bariatric surgery showed a non‑significant trend toward fewer cardiovascular events compared to both MWM and usual care.
- The analysis did not include newer agents such as semaglutide or tirzepatide, limiting its relevance to current cutting‑edge peptide therapies.
Practical Outcomes
- For biohackers, this study suggests that older weight‑loss drugs may not improve heart outcomes, so relying on them for cardiovascular protection is questionable. Newer peptides like tirzepide, which weren’t tested here, could offer different results and should be evaluated based on their own trial data. Consider bariatric surgery only after weighing risks, and keep an eye on emerging evidence for tirzepide’s cardiovascular effects.
Summary
In a real‑world look at people with obesity and type‑2 diabetes, a program that combined diet, exercise and older weight‑loss drugs (medical weight management, MWM) did NOT cut the risk of major heart‑related events compared to just usual care. Bariatric surgery hinted at fewer events, but the difference wasn’t statistically solid. The study notes that newer, more powerful drugs like tirzepatide weren’t part of the analysis, so the findings may not apply to them.
Abstract
We assessed the impact of medical weight management (MWM; lifestyle modification ± obesity medications) on major adverse cardiovascular events (MACE) compared to metabolic and bariatric surgery (MBS) and usual care (UC). We retrospectively analyzed electronic health records of adults with body mass index (BMI) ≥35 kg/m² and type 2 diabetes mellitus (T2D) at an academic health center from 2010 to 2021. The MWM group was propensity score matched on common confounders 1:1 (versus MBS) and 1:5 (versus UC). The primary outcome was a six-component MACE (all-cause mortality, coronary artery events, cerebrovascular events, heart failure, atrial fibrillation, and nephropathy).  Results: Among 2,100 patients (300 MWM, 300 MBS, and 1,500 UC), baseline characteristics were similar among groups. During a median 3.2-year follow-up (range 0-11), the adjusted hazard ratio (aHR) for MACE for MWM versus MBS was 1.61 (0.98-2.65, p=0.06); for MBS versus UC, aHR 0.66 (0.43-1.02, p=0.06); and there was no difference in MWM versus UC, aHR 1.07 (0.77-1.49, p=0.68). No statistically significant differences in MACE risk were found between those receiving MWM versus UC; there was a trend towards fewer MACE events in those receiving MBS. These findings must be validated in future studies, given that more effective weight loss medications (e.g., semaglutide, tirzepatide) were not available.
