Death In a registry-based study of 58 465 Swedish patients with diabetes aspirin significantly increased the risk of death in those without cardiovascular disease (previous or acute myocardial infarction, angina pectoris, ischemic stroke, transient ischemic attack, intermittent claudication, previous coronary artery bypass graft surgery, or percutaneous coronary intervention) by 17% (95% Cl = 1, 36) at age 50 years and by 29% (95% Cl = 16, 43) at age 85 years [70 ]. In elderly patients with diabetes with cardiovascular disease who used aspirin there was a non-significant trend towards reduced mortality, by 11% at age 85 years. The risk of serious bleeding was also increased by aspirin in those without cardiovascular disease and reduced by aspirin in those with cardiovascular disease.
