This study aims to investigate the association of estimated pulse wave velocity (ePWV) with all-cause and cardiovascular mortality in patients with diabetes. The results showed that there was a close association between the increment of ePWV and increased risks of all-cause and cardiovascular mortality in patients with diabetes. Therefore, ePWV is of great significance in assessing the mortality risk in patients with diabetes.
AimsWe aim to examine the association of estimated pulse wave velocity (ePWV) with all-cause and cardiovascular mortality in patients with diabetes.MethodsAll of adult participants with diabetes from the National Health and Nutrition Examination Survey (NHANES) (1999-2018) were enrolled. ePWV was calculated according to the previously published equation based on age and mean blood pressure. The mortality information was obtained from the National Death Index database. Weighted Kaplan-Meier (KM) plot and weighted multivariable Cox regression was used to investigate the association of ePWV with all-cause and cardiovascular mortality risks. Restricted cubic spline was adopted to visualize the relationship between ePWV and mortality risks.Results8,916 participants with diabetes were included in this study and the median follow-up duration was ten years. The mean age of study population was 59.0 +/- 11.6 years, 51.3% of the participants were male, representing 27.4 million patients with diabetes in weighted analysis. The increment of ePWV was closely associated with increased risks of all-cause mortality (HR: 1.46, 95% CI: 1.42-1.51) and cardiovascular mortality (HR: 1.59, 95% CI: 1.50-1.68). After adjusting for cofounding factors, for every 1 m/s increase in ePWV, there was a 43% increased risk of all-cause mortality (HR: 1.43, 95% CI: 1.38-1.47) and 58% increased of cardiovascular mortality (HR: 1.58, 95% CI: 1.50-1.68). ePWV had positive linear associations with all-cause and cardiovascular mortality. KM plots also showed that the risks of all-cause and cardiovascular mortality were significantly elevated in patients with higher ePWV.ConclusionsePWV had a close association with all-cause and cardiovascular mortality risks in patients with diabetes.
