Background
The objective of this study was to examine the impact of VA type on cardiovascular and all-cause mortality as well as the predictors for outcome in elderly Chinese patients.
Methods
In the retrospective study, patients who initiated HD aged ≥ 70 years and received a primary VA creation were enrolled between January 2007 and October 2018. Clinical characteristics of VA, and outcomes were collected from the electronic medical record and the local Death Index. Kaplan-Meier analysis, and multivariate regression analysis were employed.
Results
A total of 358 elderly Chinese HD patients with median aged 74(72-78) years was analyzed. During the study period of 25.8 (12-43) months, 54 patients (15.1%) and 113 patients (15.1%) died of cardiovascular events and all-cause, respectively. The modality of VA type was not associated with mortality. Furthermore, CHF and DBP were the independent predictors for cardiovascular mortality (HR for CHF =3.462; HR for DBP per 1 mmHg elevated =1.033).
Conclusion
The modality of VA types showed insignificant effect on mortality in elderly Chinese population, while the presence of CHF and preoperative DBP might be used for the risk assessment of cardiovascular death.
