Outcomes in patients with peripheral vascular disease following percutaneous coronary intervention
Catheterization and Cardiovascular Interventions Feb 26, 2019
Ramzy J, et al. – In this study, researchers examined the clinical characteristics and outcomes of patients with peripheral vascular disease (PVD) undergoing percutaneous coronary intervention (PCI) in a contemporary setting, and assessed whether use of drug-eluting stents (DESs) improves outcomes. The study sample consisted of 18,380 patients undergoing PCI from an Australian registry between 2005 and 2013. Comparisons regarding clinical and procedural data, and 30-day and 12-month outcomes were made between those with and without a reported history of PVD. They also compared outcomes between those who received DES and those who received bare-metal stent (BMS). Using Australian National Death Index (NDI) linkage, they compared long-term mortality as well. The characteristics of patients with PVD (n=1,251; 6.8%) were found to be: old age, greater diabetes prevalence, hypertension, cerebrovascular disease, heart failure, renal impairment, ostial lesions, left main, and multi-vessel disease. In patients undergoing PCI, adverse outcomes were independently predicted by PVD. Improved outcomes were observed among those who received DES vs those receiving BMS.
