Sex and ethnic differences in use of myocardial revascularization procedures in Mexican Americans and non-hispanic whites : The corpus christi heart project.
Age-adjusted rates of percutaneous transluminal coronary angioplasty (PTCA) and aortocoronary, bypass surgery (ACBS) were determined for Mexican American (MA) and non-Hispanic white (NHW) patients hospiralized for coronary heart disease.
Hypotheses of equal receipt of procedures between gender and ethnic groups were tested.
Following myocardial infarction (MI), women were less likely than men to receive eirher procedure (22 versus 32%, p<0.01), and MA were less likely than NHW to receive PTCA (13 versus 23%, p<0.01) but not ACBS.
After adjustment for extent of disease and other potential confounders, ethnic groups differed marginally in receipt of PTCA but not ACBS, while gender differences were not significant.
Although women received revascularization procedures less frequently than men, this difference did not persist after controlling for extent of coronary artery disease by angiography ; therefore, these observed differences in delivery of health care services may be appropriate.
Mexican Americans received PTCA, but not ACBS, less frequently than NHW.
This selective ethnic difference in receipt of PTCA does not appear to be associated with the extent of disease or other medical characteristics, and may represent inappropriate bias in delivery of health care services.
