Transient and persistent renal dysfunction are predictors of survival after percutaneous coronary intervention: Insights from the Dartmouth Dynamic Registry

Objectives: We sought to determine if transient and persistent elevations in creatinine following percutaneous coronary intervention (PCI) resulted in poor survival. Background: Limited survival data exist that defines the natural survival history of transient and persistent renal dysfunction following interventional PCI cases. Methods: Data were collected prospectively on 7,856 consecutive patients undergoing PCI from January 1, 2000 to July 31, 2006. Ninety‐three patients were excluded due to pre‐PCI dialysis. Patients were stratified into three categories of renal dysfunction: no renal dysfunction from baseline (
