An Evaluation of the KCCQ Score in Predicting Cardiovascular Risk in Dialysis Patients

Investigators will apply the KCCQ to maintenance dialysis patients and statistically analyze baseline KCCQ scores and changing trends to investigate whether they are associated with the occurrence of long-term cardiovascular events and all-cause mortality in dialysis patients and to construct a predictive model associated with KCCQ scores. Patients who meet the inclusion and exclusion criteria will sign an informed consent form, and the baseline index test and the KCCQ assessment will be performed within one week after enrollment. Then the follow-up will be conducted according to the follow-up plan (KCCQ scores and test indexes will be collected at 0, 1, 2, 3, 6, 9 and 12 months in patients with new-onset uremia and the patients with maintenance dialysis will be collected at 0, 3, 6, 9 and 12 months). Conduct a KCCQ assessment and collect relevant indicators during each follow-up visit. There is no intervention in the patient's treatment regimen during the study period. All participants enrolled in the study will be followed up for at least 12 months.
