heptadecanoic acid/hypoxia

Altered myocardial energy metabolism has been linked to worsening of RV function in pulmonary arterial hypertension (PAH). The aim of this study was to evaluate RV glucose and fatty acid metabolism in vivo in a rat model of PAH using positron emission tomography (PET) and investigate the effects of

To study the sensitivity of two fatty acid tracers to changes in beta-oxidation, the myocardial retention kinetics of 125I-iodine-15-(p-iodophenyl)-3(R,S)-methylpentadecanoic acid (BMIPP) and 14-18F-fluoro-6-thia-heptadecanoic acid (FTHA) were compared in states of oxygen deprivation due to ischemia

In severe pulmonary hypertension (SPH), prior studies have shown an increase in right ventricle (RV) uptake of glucose, but it is unclear whether there is a change in the relative utilization of fatty acids. We hypothesized that in the RV in SPH, as in left ventricular (LV) failure, there is altered

Interest remains strong for the development of a noninvasive technique for assessment of regional fatty acid oxidation rate in the myocardium. (18)F-labeled 4-thia palmitate (FTP, 16-[(18)F]fluoro-4-thia-hexadecanoic acid) has been synthesized and preliminarily evaluated as a metabolically trapped
