Abstract
AbstractHelicobacter pylori (H. pylori) screening and treatment is recommended for patients on chronic aspirin (ASA) therapy to reduce the risk of gastrointestinal bleeding. Coronary artery disease patients requiring combination antithrombotic therapy (dual antiplatelet therapy; DAPT, or dual pathway inhibition; DPI) are at an even higher risk of GI bleeding. Therefore, we aimed to evaluate the prevalence of H. pylori among patients referred for angiography and likely to receive DAPT or DPI. This single-center prospective observational study recruited patients undergoing coronary angiography and with the possibility of requiring DAPT or DPI. All included patients underwent H. pylori serology testing. Multivariable logistic regression was performed to determine predictors of seropositivity. 195 patients were included in the analysis. Mean age was 67 years, 50% had known prior CAD, and 49% underwent coronary intervention. H. pylori serology was positive in 36%. Chronic kidney disease (odds ratio [OR] 2.76; 95% confidence interval [CI] 1.24 to 6.15; p = 0.01) and chronic obstructive pulmonary disease (OR 2.52; 95% CI 1.14 to 5.55; p = 0.02) history were independent predictors of H. pylori seropositivity. Given the clinically significant prevalence of H. pylori seropositivity among patients referred for angiography, systematic screening strategies and eradication of H. pylori could significantly reduce the incidence of GI bleeding in patients requiring DAPT or DPI.
