How Semaglutide Works for Cardiac Health

GLP-1 reduces inflammation, improves lipids, and has direct cardioprotective effects.

About Cardiac Health

Support for heart function and cardiovascular health.

Research Evidence

STEP trials: 15-17% weight loss. FLOW trial: 24% reduction in kidney disease progression (Jan 2025 approval). Wegovy pill: 16.6% weight loss (Dec 2025 approval). Oral Rybelsus approved for CV risk reduction (Oct 2025). In January 2025, Ozempic received FDA approval for reducing kidney disease progression in T2D patients with CKD. In March 2026, Wegovy HD (7.2mg) was approved, delivering 20.7% mean weight loss — the highest for any injectable semaglutide dose.

Clinical Status:FDA Approved - T2D, weight loss, CV risk, CKD/kidney protection (Jan 2025); Oral Wegovy approved Dec 2025; Wegovy HD 7.2mg injection approved March 2026 (STEP UP: 18.7% mean weight loss, new dysesthesia safety signal at 22.9%); Wegovy 2.4mg approved April 2026 for non-cirrhotic MASH (first GLP-1 for this indication); generic semaglutide tentative FDA approval to Apotex April 10, 2026

Other Peptides for Cardiac Health

These peptides are also researched for cardiac health.

Tirzepatide

FDA

A dual GIP/GLP-1 receptor agonist representing the next generation of incretin-based therapies. Shows superior weight loss compared to semaglutide in head-to-head trials. First medication approved for obstructive sleep apnea.

Retatrutide

Clinical Trials

A triple agonist targeting GLP-1, GIP, and glucagon receptors. Phase 3 trials show up to 28.7% weight loss (71 lbs average), the highest of any obesity drug. Expected FDA approval late 2026 to early 2027.

AOD-9604

Clinical Trials

A modified fragment of human growth hormone (amino acids 177-191) studied for fat metabolism effects without the broader hormonal effects of full GH.

Liraglutide

FDA

An FDA-approved GLP-1 receptor agonist for type 2 diabetes and chronic weight management. The predecessor to semaglutide with daily dosing.
