Effectiveness of tirzepatide in patients with HFpEF using a target trial emulation retrospective cohort study
Abstract
Tirzepatide, a dual agonist of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, has shown promise in improving metabolic and cardiovascular profiles in patients with obesity. However, its potential benefits in patients with heart failure with preserved ejection fraction (HFpEF) remain unclear. We conducted a real-world, retrospective cohort study using the TriNetX global database. A total of 14,154 patients with HFpEF were included after 1:1 propensity score matching. Tirzepatide use was associated with significantly lower risks of the primary composite outcome of heart failure exacerbation and all-cause mortality (HR 0.52), as well as reductions in major adverse cardiovascular events (HR 0.64) and major adverse kidney events (HR 0.44). Subgroup analyses demonstrated consistent benefits across different strata. Sensitivity analyses using alternative exposure definitions confirmed the robustness of the findings. These results support the potential clinical utility of tirzepatide in HFpEF management and warrant further investigation in randomized controlled trials. Tirzepatide has shown promise for treatment of obesity but its effects in heart failure are unknown. Using real-world data from over 14,000 patients, the authors show that tirzepatide is associated with lower risks of death, heart failure worsening, cardiovascular events, and kidney complications in people with preserved ejection fraction heart failure.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 14,154 participants or records.
