Multiple Choice

A 45-year-old man is diagnosed with dilated nonischemic cardiomyopathy.  Late gadolinium enhancement cardiac magnetic resonance (CMR) imaging shows a left ventricular ejection fraction (LVEF) of 20% and evidence of extensive midwall myocardial scarring.  A recent study determined prognosis in patients with dilated cardiomyopathy using CMR-derived LVEF and evidence of midwall myocardial scarring (fibrosis) .  Two models were assessed: one model was based on LVEF alone, and the other incorporated the presence or absence of fibrosis.  The following 5-year prediction curves were reported: A 45-year-old man is diagnosed with dilated nonischemic cardiomyopathy.  Late gadolinium enhancement cardiac magnetic resonance (CMR) imaging shows a left ventricular ejection fraction (LVEF) of 20% and evidence of extensive midwall myocardial scarring.  A recent study determined prognosis in patients with dilated cardiomyopathy using CMR-derived LVEF and evidence of midwall myocardial scarring (fibrosis) .  Two models were assessed: one model was based on LVEF alone, and the other incorporated the presence or absence of fibrosis.  The following 5-year prediction curves were reported: Based on the study results, what is the approximate predicted 5-year all-cause mortality for this patient?
