Background Both aspirin and clopidogrel reduce the rate of cardiovascularevents in patients with coronary heart disease. We estimatedthe cost effectiveness of the increased use of aspirin, clopidogrel,or both for secondary prevention in patients with coronary heartdisease.
Methods We used the Coronary Heart Disease Policy Model, a computersimulation of the U.S. population, to estimate the incrementalcost effectiveness (in dollars per quality-adjusted years oflife gained) of four strategies in patients over 35 years ofage with coronary disease from 2003 to 2027: aspirin for alleligible patients (i.e., those who were not allergic to or intolerantof aspirin), aspirin for all eligible patients plus clopidogrelfor patients who were ineligible for aspirin, clopidogrel forall patients, and the combination of aspirin for all eligiblepatients plus clopidogrel for all patients.
Results The extension of aspirin therapy from the current levelsof use to all eligible patients for 25 years would have an estimatedcost-effectiveness ratio of about $11,000 per quality-adjustedyear of life gained. The addition of clopidogrel for the 5 percentof patients who are ineligible for aspirin would cost about$31,000 per quality-adjusted year of life gained. Clopidogrelalone in all patients or in routine combination with aspirinhad an incremental cost of more than $130,000 per quality-adjustedyear of life gained and remained financially unattractive acrossa wide range of assumptions. However, clopidogrel alone or incombination with aspirin would cost less than $50,000 per quality-adjustedyear of life gained if its price were reduced by 70 to 82 percent,to $1.00 and $0.60 per day, respectively.
