Abstract
We sought to identify baseline clinical, angiographic, and hemodynamic variables associated with optimal bare-metal stent (BMS) deployment, allowing selection of patients for treatment with BMS.Patients with fractional flow reserve (FFR) >0.90 after BMS have low (<6%) major adverse cardiac event rates (MACE). We hypothesized that baseline variables can predict post-stent FFR >0.90 and MACE after BMS.In 586 patients from the multicenter post-BMS FFR registry, we developed multivariable logistic regression models to identify clinical, angiographic, and hemodynamic variables associated with post-stent FFR >or=0.90 and 6-month MACE.After adjusting for potential confounders, baseline FFR (odds ratio [OR]: 5.0) and stent diameter (OR: 2.5 per millimeter) were predictive of post-stent FFR >0.90. Lower FFR (OR: 7.8); smaller stent diameter (OR: 3.7 per millimeter); longer stent length (OR: 1.0 per millimeter); and larger minimal luminal diameter (OR: 2.2 per millimeter) were predictors of MACE. In patients receiving 3-mm diameter stents, baseline FFR >0.70 yielded significantly higher likelihood of achieving post-stent FFR >0.90 than baseline FFR
