The COGENT study was flawed. The patients received either clopidogrel and PPI or clopidogrel, but both received enteric coated aspirin of unknown strength. Clopidogrel and PPI is still suspect since aspirin was used. A real study would have tested clopidogrel and PPI without aspirin. All the Bhatt study proved is that aspirin is your best bet.
Dr. Bhatt’s important study is well-designed and executed. I would note, however, that some other investigators have reported opposing results. One recent study, in particular, conducted by Charlot et al., 2010, and published in the Annals of Internal Medicine, involved an initial sample of over 24,000 patients. The study showed that PPIs do increase the risk of adverse cardiovascular events during the first year following MI.
