Racial and ethnic differences in the use of cardiovascular procedures: Findings from the California Cooperative Cardiovascular Project

Objectives. This study used data from the California Cooperative Cardiovascular Project to examine the use of invasive and noninvasive cardiovascular procedures among Whites, African Americans, and Hispanics. Methods. The use of catheterization, percutaneous transluminal coronary angioplasty (PTCA), coronary artery bypass graft (CABG) surgery, and several noninvasive tests among all patients 65 years or older with a confirmed acute myocardial infarction in nonfederal hospitals from 1994 to 1995 was studied. Results. African Americans (n = 527) were less likely than Whites (n = 9489) to have received catheterization (adjusted odds ratio [OR] = 0.62, 95% confidence interval [CI] = 0.50, 0.76), PTCA (OR = 0.64. 95% CI = 0.49, 0.85). or CABG surgery (OR = 0.42, 95% CI = 0.27, 0.64); somewhat more likely to have received a stress test or an echocardiogram; and equally likely to have received a multiple-gated acquisition scan. Hispanics (n = 689) also were less likely than Whites to have received catheterization (OR = 0.82, 95% CI = 0.68, 0.98) or PTCA (OR = 0.58, 95% CI = 0.45, 0.75). Conclusions. African Americans were less likely than Whites to undergo costly invasive cardiovascular procedures. In addition Hispanics were less likely than Whites to have received catheterization and PTCA.
