Key result
The presence of delayed enhancement on cardiac magnetic resonance imaging was a significant independent predictor of future cardiac events (HR 8.06) in patients with non-ischemic cardiomyopathy.

May refine prognostication in non-ischemic cardiomyopathy; leaves open whether CMR findings should guide therapy.
Cohort (n=79)
Does the presence of delayed enhancement on CMR predict cardiac events in patients with non-ischemic cardiomyopathy?
Hazard Ratio: 8.06 (95% CI 1.03–63.41)
Absolute Event Rate: 30.9% vs 2.7%
p-value: p=<0.05
The presence of delayed enhancement on cardiac MRI is a strong independent predictor of adverse cardiac events and lack of functional recovery in patients with non-ischemic cardiomyopathy.
Cho et al. (2010) conducted a cohort in Non-Ischemic Cardiomyopathy (n=79). Presence of delayed enhancement on cardiac magnetic resonance imaging vs. Absence of delayed enhancement was evaluated on Cardiac events (rehospitalization for worsening heart failure, cardiac transplantation, or death) (HR 8.06, 95% CI 1.03-63.41, p=<0.05). The presence of delayed enhancement on cardiac magnetic resonance imaging was a significant independent predictor of future cardiac events (HR 8.06) in patients with non-ischemic cardiomyopathy.
