J Am Coll Cardiol, doi:10.1016/j.jacc.2010.09.010 (Published online 8 November 2010) 2010 by the American College of Cardiology Foundation This article has been co-published in the American Journal of Gastroenterology and Circulation.

Conclusions

Among patients receiving aspirin and clopidogrel, prophylactic use of a PPI reduced the rate of upper gastrointestinal bleeding. There was no apparent cardiovascular interaction between clopidogrel and omeprazole, but our results do not rule out a clinically meaningful difference in cardiovascular events due to use of a PPI.

Cazuri A 29-year-old man presents with intermittent epigastric discomfort, without weight loss or evidence of gastrointestinal bleeding. He reports no use of aspirin or nonsteroidal antiinflammatory drugs (NSAIDs). Abdominal examination reveals epigastric tenderness. A serologic test forHelicobacter pyloriis positive, and he receives a 10-day course of triple therapy (omeprazole, amoxicillin, and clarithromycin). Six weeks later, he returns with the same symptoms. How should his case be further evaluated and managed?

A 53-year-old man, who is otherwise healthy and has a 20-year history of occasional heartburn, reports having had worsening heartburn for the past 12 months, with daily symptoms that disturb his sleep. He reports having had no dysphagia, gastrointestinal bleeding, or weight loss and in fact has recently gained 20 lb (9 kg). What would you advise regarding his evaluation and treatment?
