Impact and Mechanism of Depression on Cardio-cerebral Vascular Events and Arteriovenous Fistula Dysfunction in MHD Patients

The Impact and Mechanism of Depression on Cardio-cerebral Vascular Events and Arteriovenous Fistula Dysfunction in Hemodialysis Patients: A Single Center and Real-world Study

Depression is a common psychiatric disorder in patients on maintenance hemodialysis (MHD). It may contribute to poor prognosis in a number of ways, including its effect on platelet function. We aimed to investigate the impact and underlying mechanisms of depression on the occurrence of cardio-cerebral vascular events (CCVE) and dysfunction of arteriovenous fistula (DAVF) in MHD patients.

In this study, MHD patients were recruited and divided into depression and non-depression groups using the Hamilton Depression Scale (HAMD) in this prospective cohort study. Their clinical and laboratory indicators were collected and the occurrence of CCVE and DAVF were recorded through clinical follow-up, and analyzed, and the differences and possible influencing factors of CCVE and DAVF occurrence were assessed between the two groups of patients.

Inclusion Criteria:

• Patients had undergone dialysis treatment for more than 3 months, and their medical status was stable at the time of enrollment, with an expected survival period of more than 1 year

Exclusion Criteria:

• (1) with communication disorders or mental illness other than depression; (2) a combination of cirrhosis, lymphoma, thrombocytopenic purpura, or other diseases that significantly affect platelet function; (3) complicated with malignant tumors, tuberculosis, severe heart failure, and unstable medical conditions; (4) inability or unwillingness to cooperate with researchers.
