BackgroundMultivessel coronary artery disease carries significant mortality risk. Comprehensive data on inhospital outcomes following multivessel percutaneous coronary intervention (MVPCI) are sparse.MethodsWe queried the Healthcare Cost and Utilization Project's nationwide inpatient sample (NIS) between 2006 and 2011 using different International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The primary outcome was inhospital all-cause mortality, and the secondary outcome was a composite of inhospital mortality and periprocedural complications.ResultsThe overall mortality was low at 0.73% following MVPCI. Multivariate analysis revealed that (odds ratio, 95% confidence interval, P value) age (1.63, 1.48-1.79; <.001), female sex (1.19, 1.00-1.42; P = .05), acute myocardial infarction (AMI; 2.97, 2.35-3.74; <.001), shock (17.24, 13.61-21.85; <.001), a higher burden of comorbidities (2.09, 1.32-3.29; .002), and emergent/urgent procedure status (1.67, 1.30-2.16; <.001) are important predictors of primary and secondary outcomes. MVPCI was associated with higher mortality, length of stay (LOS), and cost of care as compared to single vessel single stent PCI.ConclusionMVPCI is associated with higher inhospital mortality, LOS, and hospitalization costs compared to single vessel, single stent PCI. Higher volume hospitals had lower overall postprocedural mortality rate along with shorter LOS and lower hospitalization costs following MVPCI.© The Author(s) 2015.
