Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This proposal is designed to test the hypothesis that humans shift to reliance on ketone bodies as a cardiac fuel source during the development of HF. The investigator also propose that this shift to ketone utilization can be detected by metabolomic profiling of blood. Specific Aim 1: To determine if the failing human heart exhibits increased extraction of blood-borne ketone bodies. Ketone bodies will be measured in coronary sinus, arterial, and central venous blood samples to determine AV differences. The HF group will be comprised of patients undergoing cardiac resynchronization therapy with an implantable cardioverter-defibrillator. The Control group will be compromised of patients without evidence of structural heart disease who are undergoing catheter ablation for supraventricular tachycardia. Specific Aim 2: To determine whether blood samples from humans with HF display metabolomic signatures indicative of increased myocardial ketone body utilization. Quantitative targeted metabolomics will be performed on the samples described in Aim 1 to determine if metabolite markers (e.g. C4-OH acylcarnitine, acetylcarnitine, succinate) found to be associated with increased myocardial ketone body oxidation in animal models are increased in the human HF group compared to the controls.
