Diabetic retinopathy is associated with pulse wave velocity, not with the augmentation index of pulse waveform
Abstract
Abstract Background To investigate the clinical differences between pulse wave velocity and augmentation index in diabetic retinopathy. Methods The subjects were 201 patients with type 2 diabetes. These subjects were measured for both augmentation index (AI) and brachial-ankle pulse wave velocity (baPWV) by a pulse wave analyzer. The relationships between AI, baPWV, and diabetic retinopathy were examined. Results BaPWV was significantly higher in patients with diabetic retinopathy than in individuals without the disease. (20.13 ± 3.66 vs.17.14 ± 3.60 m/s p Conclusion BaPWV is associated with diabetic retinopathy, but AI is not. The clinical significance appears to be different between PWV and AI in patients with diabetes.
