Cardiovascular disease has many facets, and the metabolism of branched-chain amino acids also play a role in heart disease. Branched-chain amino acids, also referred to as BCAA’s, also play a key role in organisms in general, concerning the metabolism processes as well as in cardiovascular protection, say VH Lyzohum, TV Zaval’s’ka, et al., from the Ukraine.

The researchers said that branched-chain amino acids were pivotal in the “mitochondrial biogenesis, antioxidant and antiaging processes, its antihypertension and antiarrhythmic effects, its role in obesity and diabetes mellitus” as well. Cardiovascular disease and BCAA/BCKA catabolism’s role in the action of heart failure are related. But how?

Branched-chain amino acids role in heart disease

The images in this article, according scientists, Y Huang, M Zhou, et al., from the Department of Pathophysiology, Key Laboratory of Cell Differentiation and Apoptosis of Chinese Ministry of Education, at the Shanghai Jiaotong University School of Medicine, in Shanghai, China, are of the “potential impact of reduced expression of PP2Cm in stressed heart in BCAA catabolism and cardiac remodelling. … BCAA, branched-chain amino acids; BCKA, branched-chain keto acids…” and show the role of branched-chain amino acids.

But what exactly is the role of branched-chain amino acids in such heart disease? The researchers’ question was whether it was an epiphenomenon or an actual culprit?

Their research showed that in order to understand the pathogenesis of why the heart fails, there has to be metabolic remodeling. They claim that even though we have knowledge about heart failure, less is known about why amino acid metabolism has to do with the onset of heart disease itself. They said, “Although most amino acid catabolic activities are found in the liver, branched-chain amino acid (BCAA) catabolism requires activity in several non-hepatic tissues, including cardiac muscle, diaphragm, brain and kidney.”

The researchers focused on new discoveries from genetic models that were developed using branched-chain amino acids catabolic defects as well as studies in metabolomics (for both humans and animals). What they found out is that, indeed, the “potential role of BCAA catabolism in cardiac pathophysiology and have helped to distinguish BCAA metabolic defects as an under-appreciated culprit in cardiac diseases rather than an epiphenomenon associated with metabolic remodelling in the failing heart.”
