Genetics Study of In-stent Restenosis
G Protein β3 Subunit (GNB3) Polymorphism and Restenosis of Coronary Drug-eluting Stents
The investigators hypothesized that genetic variants of G protein influence the development of restenosis and clinical outcome of patients receiving drug-eluting stents (DES).
Although drug-eluting stents (DES) have reduced restenosis rates compared with bare-metal stents, the restenosis rate is still high in the high-risk group. G protein plays important roles in the signal transduction leading to vascular smooth muscle proliferation. The initial and subsequent studies suggest that the T allele of C825T polymorphism is associated with enhanced transmembrane signaling via Gi proteins.
