Contemporary PCI outcome predictors defined

(HealthDay)—For patients undergoing percutaneous coronary intervention (PCI), predictors of outcome include previous anemia, previous chronic kidney injury, and previous moderate to severe left ventricular dysfunction, according to a study published in the April 1 issue of The American Journal of Cardiology.

Uri Landes, M.D., from the Rabin Medical Center in Petach-Tikva, Israel, and colleagues defined contemporary PCI outcome predictors in a large patient cohort. Data were included for 11,441 consecutive patients who underwent PCI. Outcome end points were defined as all-cause mortality and a composite of death or nonfatal myocardial infarction during follow-up (mean, 5.5 years).

The researchers found that in addition to known predictors of death or myocardial infarction such as advanced age, female gender, urgent setting, and diabetes mellitus (hazard ratios [HRs], 1.031, 1.23, 1.23, and 1.28; all P < 0.001), previous anemia, previous chronic kidney injury, and previous moderate to severe left ventricular dysfunction were identified as predictors in multivariate analysis (HRs, 1.55, 1.93, and 2.29; all P < 0.001). There was a correlation between drug-eluting stent placement with better outcomes (HR, 0.70; P < 0.001).

"In conclusion, this analysis confirms the effect of some known predictors of PCI outcomes," the authors write. "However, the extent of their effect is modest, while other predictors may have a greater influence on outcomes."
