Disparities in inappropriate PTCA do not explain higher revascularization rates among white patients; leaves open other drivers of racial inequities.
Does the prevalence of inappropriate indications (overuse) explain the higher rates of cardiac revascularization among white patients compared to African-American patients?
Overuse of PTCA is higher among white men compared to African-American men, but this overuse does not fully explain the overall racial disparities in cardiac revascularization rates.
Schneider et al. (2001) studied this question.
