Homoarginine and all‐cause mortality: A systematic review and meta‐analysis

Background Homoarginine, a basic amino acid and analogue of L‐arginine, has been shown to exert salutary effects on vascular homoeostasis, possibly through interaction with the enzymes nitric oxide synthase and arginase. This might translate into improved survival outcomes, particularly in subjects with moderate‐high cardiovascular risk. We conducted a systematic review and meta‐analysis to investigate the association between circulating...
