Widespread use of proton pump inhibitors or potassium-competitive acid blocker has changed the status of gastrointestinal bleeding in patients with ischemic heart disease: real-world data from high volume centers
Abstract
BACKGROUND: Although proton pump inhibitors (PPIs) or potassium-competitive acid blocker (PCAB) are useful in peptic ulcer prevention, their efficacy in preventing other gastrointestinal bleeding remains unclear. This study aimed to identify the status of gastrointestinal bleeding in the modern era when PPIs are widely used. METHODS: This study included patients who underwent percutaneous coronary intervention (PCI) between 2018 and 2019 at two high-volume centers. Patients were categorized based on whether they experienced gastrointestinal bleeding within 2 years of PCI into groups A (patients who experienced gastrointestinal bleeding within 2 years after PCI) and B (patients who did not experience gastrointestinal bleeding). RESULTS: Groups A and B included 21 (4.1%) and 494 (95.9%) patients, respectively (a total of 515 patients). Age at the initial PCI (77.8±2.4 and 72.0±0.5 years in groups A and B, respectively; p = 0.02), weight (53.8±3.2 and 61.8±0.7 kg in groups A and B, respectively; p = 0.01), and concomitant warfarin use (14.3% and 2.0% in groups A and B, respectively; p = 0.0005) were significantly different between the groups. The high bleeding risk rate (90.5% and 47.6% in groups A and B, respectively; p = 0.0001) was significantly different between the groups. A total of 95.9% of patients were taking PPIs or PCAB without significant differences between the groups. However, only one patient, who was taking steroids, had a gastric ulcer during PCAB treatment.…
