OLORECTAL CANCER IS THE second most prevalent cancer worldwide. 1 There were about 1 million new cases and 500 000 deaths due to colorectal cancer in 2002. 1 It has been estimated that 1 in 20 healthy individuals will eventually develop colorectal cancer. Coronary artery disease (CAD) is the single leading cause of death in the United States and other industrialized countries. 2 We previously published a retrospective study that reported a strong Author Affiliations: Departments of Medicine (Drs A.

In real life, the incidence of gastrointestinal bleeding associated with the combination of aspirin, clopidogrel, and enoxaparin therapy was estimated to be 2.7%. Previous peptic ulcer disease or cardiogenic shock were significant independent risk factors. Coprescription with a PPI can significantly reduce the risk.

In patients with ACS or STEMI, esomeprazole is superior to famotidine in preventing upper gastrointestinal complications related to aspirin, clopidogrel, and enoxaparin or thrombolytics.

Introduction: The major complication of aspirin and clopidogrel (A+C) co-therapy is upper gastrointestinal bleeding (UGIB). However, data are unavailable for real-life situations. Furthermore, the treatment effect of antisecretory agents is unknown. Aim: This cohort study aimed to determine the occurrence of UGIB. The treatment effect of H₂-receptor antagonist (H₂RA) and proton pump inhibitor (PPI) was also analyzed. Method: The records of 987 consecutive patients on A+C co-therapy between January 2001 and September 2006 were analyzed. The follow-up ended on the dates of a first occurrence of UGIB, stopping A+C co-therapy, a change in the antisecretory class, death, or March 2007. Results: After a follow-up of 5.8 ± 6.5 months, UGIB occurred in 39 (4.0%) patients. PPI, H₂RA and control were prescribed in 213, 287 and 487 patients respectively. After adjustment for age, dose of aspirin, previous UGIB and duration of treatment, the risk was marginally reduced by H₂RA (OR = 0.43, 95% CI 0.18–0.91, p = 0.04) and significantly reduced by PPI (OR = 0.04, 95% CI 0.002–0.21, p = 0.002), as compared to control. Conclusion: The occurrence of UGIB associated with A+C co-therapy for a median of 5.8 months was 4.0%. Co-prescription with PPI was associated with a lower risk.
