Abstract
Sharma et al question whether incomplete revascularization (ICR) after percutaneous coronary intervention is a bystander reflecting greater comorbidities and more diffuse atherosclerosis or results in increased major adverse cardiovascular events (MACE). With ICR defined using a threshold diameter stenosis ≥50% on quantitative coronary angiography in our original multivariable model, ICR was an independent predictor of 1-year MACE (hazard ratio, 1.36; 95% confidence interval, 1.12–1.64; P =0.002).1 Although we attempted to adjust for other covariates (including some of those suggested by Sharma et al), not all of these were available or fully represented in this database.
