Background Several studies have reported that black patientsare less likely than white patients to undergo cardiac catheterizationafter acute myocardial infarction. The role of the race of thephysician in this pattern is unknown.
Methods We analyzed data from the Cooperative CardiovascularProject, a study of Medicare beneficiaries hospitalized foracute myocardial infarction in 1994 and 1995, to evaluate whetherdifferences between black patients and white patients in theuse of cardiac catheterization within 60 days after acute myocardialinfarction varied according to the race of their attending physician.
Results Our study cohort consisted of 35,676 white and 4039black patients with acute myocardial infarction who were treatedby 17,550 white and 588 black physicians. Black patients hadlower rates of cardiac catheterization than white patients,regardless of whether their attending physician was white (rateof catheterization, 38.4 percent vs. 45.7 percent; P<0.001)or black (38.2 percent vs. 49.6 percent, P<0.001). We didnot find a significant interaction between the race of the patientsand the race of the physicians in the use of cardiac catheterization.The adjusted mortality rate among black patients was lower thanor similar to that among white patients for up to three yearsafter the infarction.
Conclusions Racial differences in the use of cardiac catheterizationare similar among patients treated by white physicians and thosetreated by black physicians, suggesting that this pattern ofcare is independent of the race of the physician.
