Association of left ventricular systolic dysfunction with mortality in incident peritoneal dialysis patients
2018
Aim
Cardiovascular disease is associated with morbidity and mortality in peritoneal dialysis patients but the relationship between left ventricular ejection fraction (LVEF) and outcomes is unclear. This study aimed to explore the association between LVEF and mortality in incident continuous ambulatory peritoneal dialysis (CAPD) patients.
Methods
The patients were divided into three groups according to LVEF levels (>0.6, 0.5 to 0.6, and <0.5). Kaplan-Meier analysis and the Cox proportional hazards models were used to evaluate association of LVEF with mortality.
Results
Among the 594 patients, LVEF levels of >0.6, 0.5 to 0.6, and 0.6, adjusted all-cause mortality hazard ratio (HR) and 95% confidence interval (CI) for patients with LVEF 0.5 to 0.6 and <0.5 were 1.62 (1.09-2.43) and 1.93 (1.06-3.52), respectively. The corresponding adjusted cardiovascular mortality HR were 1.60 (0.94-2.47) and 2.16 (1.04-4.74), respectively.
Conclusion
Reduced LVEF is significantly associated with increased all-cause and cardiovascular mortality in incident CAPD patients.
