Elucidate the influence of intense light therapy pretreatment in patients undergoing cardiac surgery. We hypothesize that intense light exposure is associated with the peripheral stabilization of Per2 in human buccal swabs and plasma samples before surgery and with a decrease of Troponin I levels after surgery.

Do you have coronary heart disease, and are you interested in helping researchers improve how they treat and prevent this condition? This study is exploring new risk factors that may allow for more people with heart disease to get approved for an implantable cardioverter defibrillator (ICD), a device that can detect and stop irregular heartbeats. To participate in this study, you must be 18 years old or older and already have or be eligible for an ICD. This study takes place in Buffalo, New York.

This study evaluates a sensor-controlled digital game (SCDG) to motivate self-management behaviors of weight monitoring and physical activity in adults with heart failure (HF). Half of the participants will receive the SCDG app and weight monitoring and physical activity sensors and the other half will receive only the weight monitoring and physical activity sensors.

This study will address a key gap in current knowledge by assessing the mechanisms through which raising blood and myocardial NAD+ levels in humans mediates changes in mitochondrial function, protein and epigenetic modifications, as well as inflammation. Human myocardium will be obtained after 4-14 days of oral NR supplementation from advanced heart failure patients undergoing elective left ventricular assist device (LVAD) implantation. Positive results would provide evidence to proceed with further studies of NR as a mitochondria-targeted metabolic therapy in heart failure.

This study will investigate the safety, feasibility, and preliminary efficacy of thyroid hormone therapy with Liothyronine (LT3) in individuals with heart failure with preserved ejection fraction (HFpEF) and low triiodothyronine (T3) syndrome by conducting a randomized, double-blind, placebo-controlled cross-over study with a two-week washout period between treatments.
