The 7 percent of percutaneous coronary intervention patients that acquire an acute kidney injury are far more likely to die than their counterparts without kidney injuries, according to research published in Journal of the American College of Cardiology: Cardiovascular Interventions.
Researchers at the University of Colorado in Denver analyzed nearly 986,000 patients from a national PCI registry. AKI occurred in 7.1 percent of patients, and 0.3 percent of patients subsequently required dialysis. For AKI patients, in-hospital mortality was 9.7 percent, compared with control PCI patient morality, which was 0.5 percent. For patients who required dialysis, in-hospital mortality jumped to 34 percent.

Factors associated with a higher likelihood of developing AKI during PCI included ST-segment elevation heart attack presentation and cardiogenic shock. Researchers indicated that a knowledge of these risk factors could help clinicians reduce AKIs in at-risk patients undergoing PCI, according to a news release.
