Vitamin C Improves Myocardial Perfusion in Elective PCI
In patients undergoing elective percutaneous coronary intervention (PCI), vitamin C infusion both improves microperfusion and reduces markers of oxidative stress after revascularization, according to a study published in the February 2010 issue of JACC: Cardiovascular Interventions. The findings suggest that oxidative stress plays a role in causing periprocedural myocardial injury and that vitamin C may help counteract it, the authors say.
