*Deaths prevented were calculated by multiplying the age specific case fatality rate by the estimated relative risk reduction; †60% maximum uptake assumed; ‡40% maximum uptake assumed; §20% maximum uptake assumed for warfarin if 80% of patients were taking aspirin; ¶Assuming relative risk reduction (RRR) of 8%, equivalent to coronary artery bypass graft (CABG) surgery for two vessel disease.
ACE, angiotensin converting enzyme; Gp, glycoprotein.
