Left ventricular (LV) reverse remodeling (LVRR) is one of the major therapeutic goals. Whether myocardial fibrosis or inflammation would reverse associated with LVRR remains unknown.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods:<\/jats:title>\n            <jats:p>\n              A total of 157 prospectively enrolled patients with DCM underwent baseline and follow-up cardiovascular magnetic resonance examinations with a median interval of 13.7 months (interquartile range, 12.2\u201318.5 months). LVRR was defined as an absolute increase in LV ejection fraction of &gt;10% to the final value of \u226535% and a relative decrease in LV end-diastolic volume of &gt;10%.

At baseline, younger age, worse New York Heart Association class, new-onset heart failure, lower LV ejection fraction, absence of late gadolinium enhancement, lower myocardial T2, and extracellular volume were significant predictors of LVRR.
