The Coronary Drug Project (CDP) was a large clinical trial which assessed several different treatments for coronary heart disease in men with previous myocardial infarction.[1][2][3] The study was conducted from 1965 to 1985 at 53 centers and randomized 8,341 men age 30 to 64 years to six treatment groups: low-dose estrogen therapy (2.5 mg/day oral conjugated estrogens), high-dose estrogen therapy (5 mg/day oral conjugated estrogens), clofibrate (1.8 g/day), dextrothyroxine (6 mg/day), niacin (3 g/day), and placebo (lactose 3.8 mg/day).[1][3]
The high-dose estrogen group was discontinued in 1970 due to increased non-fatal cardiovascular complications and an unfavorable trend in overall mortality, while the low-dose estrogen group was discontinued in 1970 due to lack of indication of benefit and an unfavorable trend in overall mortality.[1][2][4][5][6] Both dose levels of estrogen as well as clofibrate were also found to increase the incidence of gallbladder disease in the study.[7] The dextrothyroxine group was discontinued in 1972 due to increased cardiovascular mortality.[8]
The Coronary Drug Project Aspirin Study was a substudy of the CDP which randomized men in the trial who had terminated treatment early from the estrogen and dextrothyroxine groups to either aspirin or placebo.[9][10][5]
