Aim Data on cardiovascular outcomes in elderly using proton pump inhibitors (PPI) are scant. We aimed to test the association between PPI use and the occurrence of first‐time ischemic stroke (FTIS) among elderly.Methods The electronic database of a centrally located district branch of a large health maintenance organization in Israel was retrospectively screened (2002–2016) for community‐dwelling individuals (≥65–95 years) for demographics and co‐morbidities. Follow‐up was until FTIS, death or end of study. Findings were analyzed by PPI use and occurrence of FTIS. Results 29,639 subjects (without history of stroke and use of antiplatelet aggregation drugs) mean age of 82.2 ± 5.5 years (range: 65–95 years, 38% male) were analyzed: 8,600 (29%) used PPIs. Mean follow up was 10.58 years (SD ± 5.44). Similar total and annual occurrence rates of FTIS were depicted in PPI users and non‐users (20.9% vs. 21% and 2% vs. 2.1%, respectively). On a Cox regression analysis, upon adjustment for age, gender and cardiovascular disease related risk factors, PPI use was significantly associated with lower rates of FTIS (HR 0.73, 95% C.I. 0.69–0.77, p < 0.001). The risk for FTIS was significantly lower in subjects using PPI at any dose and for any time period compared to non‐users (HR 0.9, 95% C.I. 0.85–0.96 for 7–48 yearly prescriptions and HR 0.51, 95% C.I. 0.46–0.55 for ≥49 yearly prescriptions). Conclusions PPI use was associated with lower rates of FTIS in community‐dwelling elders. Prospective large‐scale studies are needed to fully elucidate the effect of PPI in this aging population.
