Abstract
Background: Elevated pulmonary arterial pressure may increase right ventricular (RV) oxidative metabolism in patients with pulmonary hypertension (PH) and heart failure (HF). 11C- acetate positron emission tomography (PET) can be used to measure RV oxidative metabolism noninvasively. The combination of RV oxidative metabolism and cardiac work, as estimated by cardiac magnetic resonance imaging (CMR), indicates RV efficiency and can provide new insights. However, the clinical importance of these markers has not been fully studied. The purpose of this study was to investigate the possible impacts of these markers in patients with PH through 11C-acetate PET.
