Why the study?
Is diastolic dysfunction (E/E' ratio) associated with an increased risk of contrast-induced nephropathy?
Is diastolic dysfunction (E/E' ratio) associated with an increased risk of contrast-induced nephropathy?
Diastolic dysfunction, specifically the E/E' ratio, is an independent predictor of contrast-induced nephropathy and may be useful for risk stratification.
E/E' may refine pre-procedural risk stratification; hypothesis-generating and should not yet change practice.
This study demonstrated that, among echocardiographic variables, E/E' was an independent predictor of CIN. This in turn suggests that diastolic dysfunction may be a useful parameter in CIN risk stratification.
