To systematically evaluate the risks of cardiocerebral vascular events in patients with primary biliary cholangitis(PBC). Methods We carried out a Meta analysis by RevMan 5.3 software to investigate literatureon the risk of cardiocerebral vascular events in patients with PBC and controls. Results Compared with non-PBC controls,PBC patients had significantly higher risk of coronary events(RR=1.56,P=0.0002);however,the risk of cerebrovascular events showed no significant difference between these two groups(RR=1.01,P=0.94).Subgroup analysis demonstrated a significantly lower risk of transient ischemic attack or carotid stenosis in PBC patients(RR=0.63,P=0.03);however,there was no significant difference in the risk of stroke(RR=1.11,P=0.40). Conclusion Patients with PBC have an increased risk of coronary events but may have a lower risk of transient ischemic attack or carotid stenosis.
