PG - 30-5 LID - 10.1016/j.hlc.2011.09.005 [doi] AB - BACKGROUND: In acute onset cardiomyopathy, acute myocarditis is an important cause, as it is associated with a greater likelihood of recovery of cardiac function and its presence may direct specific therapies. Myocarditis can be detected by cardiac magnetic resonance imaging (CMR); however its diagnostic utility and relation to prognosis in acute onset cardiomyopathy are unknown. METHODS: We performed CMR on 61 patients with acute onset cardiomyopathy and a left ventricular ejection fraction (LVEF) <55%. CMR included assessment of myocardial function, relative myocardial oedema, myocardial inflammation (using global relative enhancement [GRE] of the myocardium 4 minutes post Gad-DTPA contrast) and necrosis or fibrosis (with late gadolinium enhancement [LGE]). Patients were followed up at six months to evaluate LVEF, morbidity and mortality. RESULTS: There was a greater improvement in LVEF at follow up in those with myocardial inflammation identified by elevated GRE compared to those without (mean increase 19.2+/-2.5% vs. 6.7+/-1.7%, p<0.001). However, the presence of myocardial oedema or LGE alone was not associated with a greater recovery of LVEF (p=NS for both). Myocardial inflammation in patients with a baseline LVEF<35% was also associated with a greater recovery of LVEF (mean increase 21.5+/-2.9% vs. 9.1+/-3.0%, p<0.01). CONCLUSION: Myocardial inflammation identified by an elevated GRE predicts recovery of LV function in patients with acute onset cardiomyopathy.
