In particular, cardiovascular events (including myocardial infarction, cardiac arrest,stroke, and pulmonary embolism) were more frequent among the patients given pare-coxib and valdecoxib than among those given placebo (2.0 percent vs. 0.5 percent; riskratio, 3.7; 95 percent confidence interval, 1.0 to 13.5; P=0.03).

The use of parecoxib and valdecoxib after CABG was associated with an increased inci-dence of cardiovascular events, arousing serious concern about the use of these drugsin such circumstances.
