NCT03448185

Brief Summary

The purpose of this study is to determine whether 1 year of supervised exercise training in obese individuals at high risk for developing HF, incorporating high intensity interval training (HIIT) two to three times per week in conjunction with daily oral administration of omega-3 poly-unsaturated fatty acids will lead to reduction in visceral adiposity, regression of myocardial triglyceride levels and improvements in cardiac diastolic and vascular function.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline at 1 Year in Myocardial Lipid Content

    Myocardial triglyceride (lipid) content will be measured using cardiac nuclear magnetic resonance spectroscopy. We quantified the total myocardial triglyceride (TG) resonance from water-suppressed spectra. Myocardial TG content relative to water (%) as well as relative amounts of myocardial TG was calculated from the available data.

    Baseline, 1 year

Secondary Outcomes (3)

  • Change From Baseline at 1 Year in Peak Volume of Oxygen (VO2)

    Baseline,1 year

  • Change From Baseline at 1 Year in Markers of Arterial Stiffness

    Baseline, 1 year

  • Change From Baseline at 1 Year in Left Ventricular Mass
