Patients with cirrhosis often have concomitant coronary artery disease and require percutaneous coronary intervention (PCI). PCI in cirrhotics can be associated with significant risks due to thrombocytopenia, possible coagulopathies, bleeding, and renal failure. Longer term risks of PCI in cirrhotics have not been well studied. Our study seeks to evaluate the 90-day outcomes of PCI in patients with cirrhosis. Patients receiving PCI were identified from the Nationwide Readmissions Database from 2010 to 2014 and stratified by the presence of co-morbid cirrhosis. The total mortality during index admission and 90-day readmissions as well as the readmissions rate were examined. Adverse events including bleeding, stroke, kidney injury, and vascular complications were also compared. Patients with cirrhosis had a significantly higher number of co-morbidities. The cirrhosis group had a higher overall 90-day mortality (10.3% vs 2.5%, p < 0.01), including during the index hospitalization (7.0% vs 1.8%, p < 0.01), as well as a higher 90-day readmission rate (38.2% vs 20.2%, p < 0.01). Patients with cirrhosis also had higher frequencies of overall 90-day adverse events (44.7% vs 17.7%, p < 0.01), including gastrointestinal bleeding (15.3% vs 2.7%, p < 0.01) and acute kidney injury (28.4% vs 10.1%, p < 0.01). In conclusion, patients with cirrhosis face a significantly higher risk of adverse outcomes including mortality, readmissions, and adverse events in the 90 days after hospitalization for PCI compared with the general population.
