Official title

The Impact of Exercise-Induced Cardiac Remodeling on Myocardial Efficiency: A Multimodality Structural, Functional, and Metabolic Evaluation.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This research study is being conducted to find out how heart function and energy use differ among healthy endurance athletes, individuals who do not exercise regularly, and patients with hypertrophic cardiomyopathy. The research study involves taking part in a cardiopulmonary exercise test (CPET), two positron emission tomography (PET) scans, an echocardiogram, and blood draws. The study will consist of a total of three visits scheduled over a maximum of two weeks. By determining how heart function and energy use differ between our three groups of healthy endurance athletes, individuals who do not exercise regularly, and patients with hypertrophic cardiomyopathy, the investigators hope to have this work translate into a novel clinical tool for differentiating pathologic changes of the heart from physiological changes in heart. This is otherwise known as "gray-zone" left ventricular hypertrophy, or enlargement of the left ventricle.
