Figure 3 Contractile Responses of Coronary Segments Distal to Stents

Contractile responses to constriction agonists for coronary arteries distal to BMS, POLY, and SES stents. (A) In the presence of N^W-nitro-_L-arginine methyl ester (L-NAME), contractile response to prostaglandin F₂ (PGF₂) was increased for SES (*p = 0.008). (B) The contractile response to endothelin (ET)-1 was also increased for SES (*p = 0.021). Abbreviations as in Figure 2.
