NCT02973633

Brief Summary

The development of symptomatic heart failure is frequently preceded by a pre-clinical period of structural remodeling in the heart. The remodeling process driving this transition, however, remains poorly understood. The investigators hypothesize that imaging the diffusion of water in the heart with MRI will allow its microstructure to be resolved. The investigators further hypothesize that the characterization of microstructural changes in the heart will help elucidate the pathogenesis of heart failure and the transition from a compensated to a decompensated state. Patients with recent myocardial infarcts and left ventricular hypertrophy, who are at risk for the development of heart failure, will be enrolled. The participants will undergo serial diffusion tensor MRI (DTI) imaging of the heart to characterize changes in myocardial microstructure over time.

Outcome Measures

Primary Outcomes (1)

  • Myofiber Helix Angle

    The investigators aim to determine how the myofibers in the heart change their orientation in heart disease by measuring their helix angle.

    12 months

Secondary Outcomes (1)

  • Correlation of Myofiber Helix Angle and Strain

    12 months

Study Arms (3)

Healthy Volunteers

ACTIVE COMPARATOR

DTI will be performed in healthy volunteers to characterize normal fiber architecture in the heart and provide a comparison group for the patients imaged in the other arms.

Device: Diffusion Tensor MRI (DTI)

Patients with Recent Myocardial Infarction

ACTIVE COMPARATOR

Patients with recent ST elevation myocardial infarcts will be recruited and imaged serially with DTI to detect changes in fiber architecture and their correlation with remodeling of the left ventricle.

Device: Diffusion Tensor MRI (DTI)Drug: Gadolinium DOTA Meglumine

Patients with Left Ventricular Hypertrophy

ACTIVE COMPARATOR

Patients with left ventricular hypertrophy and a history of heart failure will be recruited and imaged serially with DTI to detect changes in fiber architecture and their correlation with the onset and progression of heart failure.

Device: Diffusion Tensor MRI (DTI)

Interventions

Diffusion Tensor MRI (DTI) measures the diffusion of water in the heart, which allows the orientation of the muscle fibers in the heart to be determined.
