Genetic polymorphisms and the cardiovascular risk of non-steroidal anti-inflammatory drugs.

The cardiovascular safety of cyclooxygenase-2-selective (coxibs) and nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) is of concern, although most users remain free of adverse outcomes. A gene-drug interaction could modulate this cardiovascular risk through prostaglandin synthesis or inflammatory pathways. From an existing acute coronary syndrome cohort (Recurrence and Inflammation in the Acute Coronary Syndromes Study) (n = 1,210), a case-only study was performed by identifying 115 patients exposed to NSAIDs (rofecoxib [n = 43], celecoxib [n = 49], or nonselective NSAIDs [n = 23]) and 345 unexposed patients matched for age, gender, and hospital center.
