Healthcare providers, including nurses, need to be made aware of a set of characteristics (i.e., increased serum level of triglycerides, HS-CRP, and smoking) which may predict the incidence of CAD, particularly the number of stenosed coronary arteries (≥ 60%) and number of stented coronary arteries, among patients with CAD undergoing cardiac catheterization. This evidence concerns the gene CRP and coronary artery disorder.
