Abstract

Purpose: Type 2 diabetes mellitus (T2DM) is known to produce diabetic retinopathy (DR). Pulse wave analysis (PWA) provides arterial stiffness (AS) and central hemodynamic (CH) parameters. We studied the effect of DR on AS and CH parameters in type 2 diabetics (T2D).

Methods: We performed a cross-sectional study on 47 T2Ds attending a private ophthalmology clinic screened for DR by optical coherence tomography angiography and divided into NDR (non-DR), NPDR (non-proliferative DR), and PDR (proliferative DR). Mobil-o-graph (IEM, Germany) based oscillometric PWA yielded AS and CH parameters. They were further compared between groups stratified by DR with P value set at 0.05.

Results: Participants had a mean age 62, mean diabetes duration 9 years, high mean BMI, and high prevalence of physical inactivity, hypertension, and poor diseases control. Significant differences were lacking in NPDR, NDR, and PDR in rate pressure product (mean 112.71 vs 116.06 vs 119.57), central pulse pressure (mean 46.50 vs 43.09 vs 42.72), stroke work (mean 153.36 vs 132.36 vs 146.08), augmentation index (mean 29.43 vs 33.14 vs 31.64), and aortic pulse wave velocity (mean 10.06 vs 9.08 vs 9.06). There was no clear pattern of distribution of most parameters among the three subgroups.

Conclusion: We found a lack of association between DR and cardiovascular ageing studied by AS and hemodynamic parameters. It suggests a possible difference in risk factors for both of these aftermaths of T2DM and calls for further prospective studies with a large sample size.
