Potential Cardiovascular Risks of Proton Pump Inhibitors in the General Population

抄録

Proton pump inhibitors (PPIs) are the most effective gastric acid-suppressing agents and the mainstay medical therapy for a series of acid peptic diseases. In general, the safety profile of PPIs is excellent. However, with long-term drug administration, the safety and potency of PPIs has been questioned. In the cardiovascular field, drug-drug interactions related to PPIs have been identified with particular attention regarding the use of PPIs combined with clopidogrel in patients with acute coronary syndrome. Currently, cardiovascular risks from PPIs may extend from patients with coronary artery disease to the general population. This review summarizes the possible cardiovascular risks in PPI users with no history of cardiovascular diseases and discusses possible biological mechanisms.
