View larger version (27K): [in a new window]   Figure 2 Stratification of risk for repeat revascularization at six months for patients with optimal (stent-like) angiographic results. Using three baseline characteristics (gender, lesion length and lesion location), patients are classified as low risk (repeat revascularization rate of 14%) or high risk (repeat revascularization rate of 25%). DS = diameter stenosis; LAD = left anterior descending coronary artery.
