Abstrakt: Introduction: Cardiac autonomic neuropathy (CAN) is a key complication of type 2 diabetes mellitus (Ty2DM). Vascular endothelial-derived growth factor (VEGF-A) plays a key role in diabetic macrovascular and microvascular complications. It is shown to be elevated in diabetic neuropathy and has the potential to serve as a biomarker in Ty2DM. We evaluated VEGF-A levels and cardiac autonomic function in newly diagnosed Ty2DM patients.
Materials and Methods: Forty-four newly diagnosed patients (with symptoms within 1 year from the date of recruitment) were included in the study. Cardiac autonomic function was assessed using heart rate variability (HRV) and Ewing's battery tests. Ewing's scores were computed and tabulated. VEGF-A levels were estimated using enzyme-linked immunosorbent assay (ELISA).
Results: The patients demonstrated normal responses to the reactivity tests. Ewing's scores were 0 (0-0) and 0 (0-0) for sympathetic and parasympathetic parameters, respectively. The autonomic tone was impaired as assessed by HRV parameters. VEGF-A levels were elevated (308.3 ± 167.2 pg/mL) when compared with the previous literature.
Discussion: Impaired tone with normal reactivity was suggestive of early stage of autonomic neuropathy. Elevated VEGF-A levels may be attributed to a protective action of the factor seen in early stages of neuropathy in Ty2DM. Serial VEGF-A estimation in large cohorts of newly diagnosed diabetics may validate it as a biomarker in CAN seen in Ty2DM.
