Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| cardio-cerebral vascular events (CCVE) | 1 year | CCVEs were defined as the first occurrence of angina pectoris, myocardial infarction, episodes of heart failure requiring clinical intervention, arrhythmic episodes with clinically significant symptoms, transient ischemic attack, cerebral infarction, and cerebral hemorrhage during the observational period. |
| dysfunction of arteriovenous fistula (DAVF) | 1 year | DAVF was diagnosed if a patient presented with any one or more of the following conditions that render his or her AVF unsatisfactory for effective hemodialysis: (1) loss of AVF murmur on clinical auscultation; (2) notable weakening or disappearance of pulsation in AVF; (3) echography showing interruption of blood flow, thrombosis within the internal fistula, or stenosis of the venous outflow tract at or near the anastomotic site; or (4) maximum blood flow \<200 mL/min in AVF during dialysis. |
