The authors of this review suggest chronic systemic inflammation as the linkage point between rheumatoid arthritis (RA) and increased cardiovascular dysfunction often associated with RA (see: Solomon DH et al, Circulation. 2003 Mar 11;107(9):1303-7). This review reports on the anti-inflammatory actions of the green tea extract epigallocatechin-3 gallate (EGCG) in multiple studies and suggests its benefit for both rheumatoid arthritis and cardiovascular disease.
