“Fatty acid metabolism in pulmonary arterial hypertension: role in right ventricular dysfunction and hypertrophy” – A Review

In the below I will be referencing and discussing quotes from the paper “Fatty acid metabolism in pulmonary arterial hypertension: role in right ventricular dysfunction and hypertrophy” by M. Talati. Basically, I’m distilling the key points that I’ve learned, summarizing them, and including any thoughts I may have. Overall it appears that the running thread through this paper is the following: Can metabolic syndrome or insulin resistance in PH cause RV dysfunction? Or is the dysfunction a result of PH? In sum, there is a dysregulation in fatty acid oxidation and glucose oxidation, with increased intracellular lipid accumulation, and an overall switch

Thought Of The Day – AMPK, Pulmonary Vasculature & RV

Today’s thought stems from a quote I found reading Metabolic Regulation: A Human Perspective by Keith N. Frayn. This is one of my new favorite books… Quote: “AMPK senses energy status of the cell: when there is a drain on ATP, AMP rises and the AMPK is activated, leading in turn to inhibition of ATP utilizing pathways (particularly biosynthetic pathways) and activation of ATP-generating pathways (glucose uptake, glycolysis, fatty acid oxidation).” Thought: AMPK (5′ AMP-activated protein kinase) activation in some form, either via dietary means, or as a drug target, would seem to be a good idea for the pulmonary vasculature as
