Temporal trends in the utilization and outcomes of percutaneous coronary interventions in patients with liver cirrhosis

Abstract Objectives We sought to assess the national trends in the utilization and outcomes of percutaneous coronary interventions (PCI) in patients with cirrhosis. Background Contemporary data on PCI in patients with liver cirrhosis are limited. Methods The National‐Inpatient‐Sample was used to identify patients who underwent PCI between 2003 and 2016. We examined the annual PCI rate, and compared the in‐hospital morbidity, mortality, resource utilization, and cost following PCI in patients with and without cirrhosis. Results A total of 8,860,178 PCI hospitalizations were identified, of those, 20,339 (0.2%) were performed in patients with cirrhosis. Annual PCI rates decreased overtime in patients without liver cirrhosis but increased in those with cirrhosis ( P trend < .001). Patients with cirrhosis had a characteristic clinical, demographic, and socioeconomic profile compared with those without cirrhosis. The use of bare‐metal stents decreased from 69.1 to 11.4% in the noncirrhosis group, and from 81.9 to 21.3% in the cirrhosis group. Compared with propensity‐matched patients without cirrhosis, PCI in cirrhotic patients was associated with higher in‐hospital mortality across all indications (STEMI 19.1 vs. 11.5%, p = .002; NSTEMI 8.7 vs. 5.6%, p = .002; and UA/SIHD 7.7 vs. 4.3%, p < .001). Cirrhotic patients also had significantly higher rates of acute kidney injury, but similar rates of vascular complications and stroke. Additionally, cirrhotic patients had longer hospitalizations, were less likely to be discharged home, and accrued higher cost across all PCI indications. Conclusions Patients with cirrhosis who are deemed “suitable PCI candidates” in current practice remain at high‐risk for worse short‐term morbidity and mortality, and higher cost of care.
