This letter suggests that physicians should respond to demonstrated racial differences in the use of cardiac procedures by "seriously confronting and redressing our biases." It also notes that Shulman et al. (N Engl J Med 1999;340(8):618-26) demonstrated that there was only 75% agreement among experts on indices of probability of disease and a 50% rate of agreement among physicians in general. Thus, the suggestion is also made that physicians should respond to this article by defining the indications of and contraindications to procedures such as coronary angiography.
