White and Asian patients undergoing PCI had better long-term outcomes, including lower rates of death and MI, when compared with black and Hispanic patients, according to new research.
“Our findings are significant to clinical practice by providing clinicians with new information on long-term PCI outcomes for specific racial/ethnic groups, including data evaluating drug-eluting and bare-metal stent performance, which may help in risk stratification and treatment selection to optimize clinical outcomes and to improve resource use for black, Hispanic and Asian patients undergoing PCI for the treatment of CAD,” Robert S. Kumar, MD, with Lenox Hill Hospital, New York, and colleagues wrote.
The study included 423,965 patients (390,351 white; 20,191 black; 9,342 Hispanic; and 4,171 Asian) in the National Cardiovascular Data Registry CathPCI Registry database linked to Medicare claims for follow-up. Participants were aged older than 65 years and underwent stent implantation from 2004 to 2008.
Researchers found that black and Hispanic participants undergoing PCI had higher long-term risks of death and MI (blacks, HR=1.28; 95% CI, 1.24-1.32; Hispanics, HR=1.15; 95% CI, 1.10-1.21). Similar long-term outcomes were observed in Asians and whites (HR=0.99; 95% CI, 0.92-1.08).
Researchers also found that among all race and ethnic groups, except Hispanics, DES use was associated with better 30-month survival and lower MI rates compared with use of BMS. Hispanics had similar results with both DES and BMS.
