Soluble Receptors for Advanced Glycation End-Products and PCI

It is hypothesized that patients with low pre-PCI serum levels of sRAGE should receive DES implantation and/ or procedures taken to increase serum levels of sRAGE and/ or decrease the serum levels of AGE. The purpose of this pilot study is to afford invasive cardiologists with additional evidenced based information to guide their decision as to which patients should receive a BMS or DES for coronary implantation. The objectives of the study are to determine whether or not: 1. Patients with low pre-PCI serum levels of sRAGE who receive bare metal stents develop restenosis 2. Patients with high pre-PCI serum levels of sRAGE who receive bare metal stents will have reduced risk of the development of restenosis 3. Patients with low pre-PCI serum levels of sRAGE who receive drug eluting stents will have an increased risk of the development of restenosis
