Background Bleeding complications are not uncommon in patients with acute myocardial infarction (AMI) during treatments. How to prevent the occurrence of upper gastrointestinal bleeding in AMI patients has become one of the most intractable problems. And there are conflicting data on the efficacy and complication rate of omeprazole treatment. We conducted an intervention study to determine whether using omeprazole could benefit AMI patients. Methods A total of 237 patients with AMI were divided into two groups at random: omeprazole group including 114 patients and control group including 123 patients. Omeprazole 40 mg by intravenous drip was given to the patients in omeprazole group when they were admitted to the hospitals. From the second day they were given omeprazole 20 mg per day by oral administration for 7 days. In contrast, no gastric acid inhibitor was given to the patients in control group. The incidence of upper gastrointestinal bleeding, the recanalization rate and overall mortality in both groups were observed. Results The incidence of upper gastrointestinal bleeding in omeprazole group was 5.3% (6/114) which was much lower than 14.6% (18/123) in control group (P = 0.017), but the recanalization rate had no significant difference between the two groups (P = 0.681). The overall mortality in omeprazole group was lower than that of control group (3.5% vs. 10.6%, P = 0.035). Conclusions Our findings suggest that early use of omeprazole in AMI patients could decrease the incidence of upper gastrointestinal bleeding and the overall mortality, without influencing the recanalization rate. Early use of omeprazole might benefit AMI patients.
