['Diastolic dysfunction is a frequent cause of heart failure, particularly in dialysis patients. Advanced glycation end-products (AGEs) are increased in dialysis patients and are suggested to play a role in the development of diastolic dysfunction. The aim of our study was to assess whether AGE accumulation in dialysis patients is related to the presence of diastolic dysfunction.', "Data were analyzed from 43 dialysis patients, age 58 +/- 15 years, of whom 65% were male. Diastolic function was assessed using tissue velocity imaging (TVI) on echocardiography. Tissue AGE accumulation was measured using a validated skin-autofluorescence (skin-AF) reader. Plasma N(epsilon)-(carboxymethyl)lysine (CML) and N(epsilon)-(carboxyethyl)lysine (CEL) were measured by stable-isotope-dilution tandem mass spectrometry. Plasma pentosidine was measured by high-performance liquid chromatography. Skin-AF correlated with mean E' (r = -0.51, P < .001), E/A ratio (r = -0.39, P = .014), and E/E' (r = 0.38, P = .019). Plasma AGEs were not significantly associated with diastolic function. Multivariable linear regression analysis revealed that 54% of the variance of average E' was explained by age (P = .007), dialysis type (P = 0.016), and skin-AF (P = .013)."] Is skin-autofluorescence , a measure of tissue advanced glycation end-products ( AGEs ) , related to diastolic function in dialysis patients?
