Predictive score for target vessel revascularization after bare metal coronary stenting

The ability to estimate the rate of a new target vessel revascularization (TVR) after bare metal coronary stenting is an important issue, as the systematic use of drug-eluting stents is still limited by its high costs. We sought to create a predictive score for the possibility of a new TVR after bar...

Summary:The ability to estimate the rate of a new target vessel revascularization (TVR) after bare metal coronary stenting is an important issue, as the systematic use of drug-eluting stents is still limited by its high costs. We sought to create a predictive score for the possibility of a new TVR after bare metal stenting. Clinical and angiographic characteristics of a prospective cohort of 848 patients were included in a dedicated database. Independent predictors of 1-year TVR were identified by multivariate analysis, and the score points were assigned according to the relative risk ratio of 1-year TVR. The 1-year TVR rate in the 848 patients was 7.4%. By multivariate analysis, reference diameter, lesion length and diabetes mellitus were retained in the final model (Hosmer-Lemeshow goodness-of-fit test = 2.339; p = 0.969). The increase of 1-year TVR rates was almost linear, with each score level (0 = 1.4%, 1 = 4.5%, 2 = 7.1%, 3 = 10.4% and 4 of 5 = 15.7%; r = 0.90; p < 0.001), and the p of the Chi-square test for trend was < 0.0001. This score can stratify patients with very low and high TVR rates and can be used as a simple clinical tool for the prediction of a new revascularization procedure in daily practice.
