Abstract

This study compared the efficacy and safety of tegoprazan versus proton-pump inhibitors (PPIs) for gastrointestinal (GI) protection in patients receiving dual antiplatelet therapy (DAPT) after undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Using a Korean Nationwide database (March 2019 to September 2022), 21,276 patients treated with tegoprazan (n = 2,075) or PPIs (n = 19,201) in combination with DAPT after PCI for AMI were analyzed. The primary efficacy endpoint was GI bleeding at 1 year, and the primary safety endpoint was major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of myocardial infarction or stroke. In the crude cohort, tegoprazan was associated with a lower risk of GI bleeding and major bleeding with similar MACCEs rates at 1 year compared to PPIs. After propensity-score matching, tegoprazan was consistently associated with lower risks of GI bleeding (hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.54-0.98, P = 0.04) and major bleeding (HR 0.69, 95% CI 0.49-0.98, P = 0.04), without increasing the risk of MACCEs (HR 0.86, 95% CI 0.59-1.26, P = 0.45) at 1 year. In patients with AMI treated with DAPT, tegoprazan was associated with a significantly lower GI bleeding risk versus PPIs, without increasing ischemic events.

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 21,276 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
