Flow-mediated and nitrate-mediated dilation in following radial artery catheterisation. Flow-mediated and nitrate-mediated dilation in following radial artery catheterisation. Flow-mediated dilation (FMD) in the catheterised right radial artery is impaired at 24 hours (3.9±2.9%) when compared to baseline (8.6±4.0%, p=0.015). There was some degree of functional recovery by 3 months (6.2±4.4%) by which time FMD was not significantly different to baseline (p=0.34). Nitrate-mediated dilation (NMD) was similarly impaired at 24 hours (2.8±2.5%) when compared to baseline (9.4±5.1%, p=0.006). Again, there was some improvement by 3 months (4.8±2.7%) but this had not returned to baseline (p=0.047). A J Mitchell et al. Open Heart 2016;3:e000443 ©2016 by British Cardiovascular Society
