Level 5 - mechanism / opinion, no new human data
Narrative review of mechanistic pathways without systematic search or primary human data.

What was done
This narrative review summarizes literature regarding the sources and regulatory roles of free fatty acids (FFAs) and free fatty acid receptors (FFARs) in vascular endothelial and smooth muscle cells.
What was found
The abstract reports no quantitative measurements or statistics. It summarizes that excess FFAs promote endothelial dysfunction, vascular hypertrophy, and vessel wall stiffness, whereas FFARs regulate vascular cellular processes (proliferation, migration, apoptosis, inflammation, and angiogenesis) relevant to hypertension and atherosclerosis.
Why it matters
Elucidating the signaling intersections between circulating fatty acids and vascular FFARs could help identify targeted therapeutic strategies for arterial disease and hypertension.
Limits
As a narrative review, it provides broad mechanistic synthesis without systematic literature search criteria, meta-analytic pooling, or new clinical data.
