Clinical Outcomes of Tegoprazan Versus Proton Pump Inhibitors in Patients Receiving Antiplatelet Therapy After Percutaneous Coronary Intervention: A Retrospective, Observational Study
Abstract
Objectives: Tegoprazan is an alternative to proton pump inhibitors (PPIs). This study evaluated the occurrence of upper gastrointestinal (GI) and cardiovascular (CV) complications in patients with ischemic heart disease undergoing antiplatelet therapy after percutaneous coronary intervention (PCI) who were treated with tegoprazan or PPIs.
Methods: Data from 604 patients who received antiplatelet therapy with tegoprazan or PPIs for >6 months after PCI between March 2019 and November 2023 were retrospectively analyzed. The primary GI endpoints were symptomatic gastroduodenal ulcers and upper GI bleeding, while the primary CV endpoints comprised major adverse cardiac events (MACEs), nonfatal myocardial infarction (MI), target vessel revascularization, and death from CV-related causes.
Results: Among the 604 patients, 265 received tegoprazan and 339 received PPIs. During a mean follow-up of 17 months, seven patients experienced a GI event (0.4% with tegoprazan vs. 1.8% with PPIs; p=0.112) and 12 experienced MACEs (1.1% with tegoprazan vs. 2.7% with PPIs; p=0.183). Subgroup analysis indicated that target vessel revascularization occurred in six patients, with event rates of 0.8% (n=2) for tegoprazan and 1.2% (n=4) for PPIs (p=0.598). Tegoprazan was associated with similar rates of nonfatal MI (0.8% vs. 2.4%; p=0.125) and death from CV-related causes (0.4% vs. 0%; p=0.258) as PPIs.
Conclusions: There were no significant differences in GI- or CV-related complications between…
