Abstract

hemodynamic stimuli across physiologic (e.g., exercise) and pathologic states (e.g., hypertension, aortic stenosis). The extent ofmyocardial hypertrophy is determined by a combination of cardiomyocyte size and extracellular volume (ECV) expansion/interstitialfibrosis: while physiologic (exercise-induced) hypertrophy reflects mostly reversible cardiomyocyte hypertrophy, pathologic hypertrophy(e.g., in heart failure) is a combination of both interstitial fibrosis (potentially irreversible) and cardiomyocyte hypertro-phy (reversible).Current methods to delineate the potential for LV reverse remodeling (e.g., natriuretic peptides and echocardiographic or clinicalmarkers) detect primarily advanced disease, missing a critical opportunity to intervene and follow patients at an early disease phasewhere myocardial pathology may be reversible. Therefore, establishing novel, quantitative metrics of myocardial tissue phenotype thatdefine a transition from hypertrophy to fibrosis, and then to irreversible LV remodeling/dysfunction may facilitate targeting therapies ata modifiable stage of disease in HF. Our group has recently extended cardiac T1 mapping MRI techniques to quantify the intracellularlifetime of water (Äic) serially as an index of cardiomyocyte diameter, validating this technique histologically in mouse models ofpressure overload. The central hypothesis of this application is that these novel MRI metrics will define the role of fibrosis andcardiomyocyte size in the development of LV remodeling/HF and will be associated with prognostically important indices in HFdevelopment.
