Abstract

Background

Insulin resistance is a risk factor for cardiovascular morbidity and mortality in the general and end-stage renal disease populations. In this study, we investigated the association between insulin resistance and arterial stiffness in nondiabetic peritoneal dialysis (PD) patients.

Methods

Fifty-three patients were enrolled. Patients were divided into 2 groups as homeostasis model assessment of insulin resistance (HOMA-IR) ≤2.97 (low) and >2.97 (high). Carotid–femoral pulse wave velocity (c-f PWV) analysis and intima-media thickness of the carotid artery were measured.

Results

Mean age was 46 ± 12 years and HOMA-IR was 2.97 ± 1.77 (0.77–8.88). Mean c-f PWV was 7.6 ± 1.7 m/s. HOMA-IR was positively correlated with age, body mass index, and c-f PWV and negatively with serum HDL cholesterol and parathormone. In linear regression analysis, age and mean arterial pressure were predictors for c-f PWV. When patients were divided into 2 groups according to median age as ≤49 and >50, mean arterial pressure, male gender, and age were predictors for c-f PWV in patients aged ≤49, whereas HOMA-IR was the only predictor for c-f PWV in patients aged >50 years.

Conclusion

Insulin resistance is an independent risk factor for arterial stiffness in PD patients older than 50 years. IR is not associated with carotid intima-media thickness.

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
