BACKGROUND: Patients with coronary artery disease (CAD) treated with stents require dual antiplatelet therapy (DAPT). For cirrhotics, who often have varices and coagulopathy, it is not clear if the risk of gastrointestinal bleeding (GIB) should preclude use of DAPT.
AIM: To compare GIB and mortality rates in cirrhotics with CAD treated medically or with stents.
METHODS: Using institutional databases, we identified patients with cirrhosis and CAD treated with stents or medical therapy between January 2000-September 2015. Primary outcomes were GIB and mortality.
RESULTS: We identified 148 cirrhotics with CAD; 68 received stents (cases), 80 were treated with medical therapy (controls). Cases and controls had similar demographics, comorbidities, MELD scores and clinical presentation; DAPT was used in 98.5% of cases vs 5% of controls. The incidence of GIB was significantly higher in cases than controls (22.1% vs 5% at 1 year, P=.003; 27.9% vs 5% at 2 years, P=.0002), whereas all-cause mortality was similar (20.6% vs 21.3%). No patient required surgery or angiography for GIB, and no known patients died due to GIB. Multivariate analysis revealed use of a proton pump inhibitor (PPI) was highly protective against GIB (OR=0.26, 95%CI=0.08-0.79).
CONCLUSIONS: CAD treatment with stents in our cirrhotics was associated with a significantly increased risk of GIB, but no adverse effects on survival. Although it remains unclear whether the cardiovascular benefits of stents outweigh the GIB risk, our findings suggest that DAPT should not be withheld from stented cirrhotics for fear of GIB. Moreover, the use of a PPI should be strongly considered.
