A study of 21,848 non-emergent, high-risk patients who underwent percutaneous coronary intervention (PCI) with percutaneous ventricular assist devices (PVADs), including Impella, demonstrates the PVAD patients had a lower rate of mortality and complications than patients who underwent PCI with intra-aortic balloon pumps (IABPs).
For the study, investigators obtained their data from the National Inpatient Sampling (NIS) database, the largest all-payer inpatient care database in the United States. NIS is developed through a partnership with the Agency for Healthcare Research and Quality (AHRQ) and contains data on approximately eight million Medicare and private payer hospital stays.
