Angiogenin and osteopontin and coronary collateral circulation

Özet

We read the publication on “The association between serum angiogenin (AGN) and osteopontin (OPN) levels and coronary collateral circulation in patients with chronic total occlusion” with a great interest. Gürses et al. (1) concluded that “AGN andOPN are associated with better developed coronary collateral circulation and may have therapeutic implications for the promotion of coronary collateral development” and also noted that “the underlying mechanisms remain largely unknown”.
