Association Between Clinical Use of Lansoprazole and the Risk of Coronary Heart Disease: A Nationwide Pharmacoepidemiological Cohort Study
Abstract
PURPOSE: Proton pump inhibitors (PPIs) are widely prescribed for gastrointestinal disorders. Lansoprazole, a PPI, has been recognized for its potential effects of improving insulin resistance, reduction of oxidative stress, and improvement in atherosclerosis through peroxisome proliferator-activated receptor gamma (PPARγ) induction. This study aims to investigate whether lansoprazole poses a distinct risk of coronary heart disease (CHD) compared to other PPIs.
METHODS: A retrospective cohort study utilized data from the National Health Insurance Research Database in Taiwan spanning from 2000 to 2013. The exposed cohort included 1666 patients with lansoprazole use, while the comparison cohort comprised 6664 patients using other PPIs. The primary outcome was incident CHD. Cox regression models were employed to assess the association between lansoprazole use and CHD risk, presenting hazard ratios (HRs) and 95% confidence intervals (CIs).
RESULTS: Patients prescribed lansoprazole demonstrated a significantly reduced risk of CHD compared to those undergoing other PPI treatments in individuals without a history of CHD. Lansoprazole users exhibited a 25% lower risk of developing CHD compared to other PPI users (adjusted HR 0.75; 95% CI 0.65-0.87). Intriguingly, this inverse association between lansoprazole use and CHD risk was consistent across genders and various age groups.
CONCLUSION: This study suggests that lansoprazole is associated with a decreased risk of CHD in comparison…
