PRIMARY outcome

Timeframe: 6 months

Population: completed baseline and end-of-study cardiopulmonary exercise test

measurement of peak oxygen uptake (VO2peak) during treadmill exercise, in units of milliliters of oxygen per kilogram of fat-free mass per minute

SECONDARY outcome

Timeframe: 6 months

Population: analysis limited to those with interpretable imaging data at baseline and end of study

proton magnetic resonance spectroscopy determination of intra-myocardial triglyceride content at baseline and after 6 months, with triglyceride quantified analyzing fat and water signals assuming monoexponential signal decay and expressed as a percentage of fat-to-water (%)

SECONDARY outcome

Timeframe: 6 months
