Patients with dilated cardiomyopathy who present for indwelling right heart catheterization will be enrolled and randomized to either control or triheptanoin oil for five days. Hemodynamics will be assess serially.

Primary Outcome Measures:
  • Cardiac output/index [ Time Frame: 6 hours ]
    The main outcome of interest is the change in cardiac index over the first 6 hours of the study period (before initiation of any other vasoactive medications). Pre-and post-cardiac index will be compared with a paired t-test. With 10 patients per study group, we have 80% power to detect a clinically significant 20% difference (0.4L/min/m2) in cardiac index between treatment assignments. Assuming the need for a non-parametric analysis a "standard" 20% increase in sample size will need sought. This yields a final 12 patient per group (n=24 total) sample size

Secondary Outcome Measures:
  • Cardiac Output/index and pulmonary capillary wedge pressure [ Time Frame: 5 days ]

Estimated Enrollment: 24
Study Start Date: February 2013
Estimated Study Completion Date: February 2014
Estimated Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Triheptanoin oil
The standard dose of triheptanoin oil for adults is 1-2gm/kg/24 hours. For purposes of this study, we will administer 0.25mg/kg four-times per day. The liquid study drug will be mixed into sugar-free, low fat yogurt, pudding or nutritional supplement shake, depending on patient preference.
Drug: Triheptanoin oil
Placebo Comparator: Simple sugar
0.25mg/kg of sugar syrup will be mixed into sugar-free, low fat yogurt, pudding or nutritional supplement shake four-times per day before meals.
