Hispanics Show Lower Artery Bypass Rate After PCI

They had fewer CABG surgeries than Caucasians a year after percutaneous coronary intervention

FRIDAY, Sept. 18 (HealthDay News) -- Despite having a higher cardiovascular risk profile than Caucasians, Hispanics are less likely to have coronary artery bypass graft (CABG) surgery in the year after percutaneous coronary intervention (PCI), according to research published in the Sept. 15 issue of the American Journal of Cardiology.

Shailja V. Parikh, M.D., of the University of Texas Southwestern in Dallas, and colleagues analyzed data from nearly 1,900 Hispanic and Caucasian patients in the National Heart, Lung, and Blood Institute Dynamic Registry who underwent PCI.

The researchers found that Hispanic patients were more likely to have hypertension and diabetes. The groups had a similar incidence of one-year hospitalization for angina, but Hispanics were more likely to report recent angina. Hispanics had lower rates of CABG surgery at one year (hazard ratio, 0.43) and a trend toward less repeat revascularization (hazard ratio, 0.76). Hispanics and Caucasians had similar rates of death and myocardial infarction at one year.

"In our study, despite longer lesions and more insulin-treated diabetes mellitus, Hispanic patients had equivalent rates of repeat PCI and were less likely to undergo CABG compared to Caucasian patients. Whether or not Hispanic patients possess any intrinsic or lifestyle factors that could be protective toward restenosis remains to be determined," the authors write.
