About 10% and 5% of the patients assigned to low-dose aspirin and placebo, respectively, had recurrent ulcer bleeding within 30 days. At 8 weeks, fewer aspirin recipients than placebo recipients had died (1% [1 of 78 patients] vs. 13% [10 of 78 patients]). The cause of death in the patient who received aspirin was heart failure. In the placebo group, 2 patients died of acute coronary syndrome, 2 of stroke, 2 of heart failure, 3 of perforated ulcer or uncontrolled ulcer bleeding, and 2 of pneumonia.
