Abstract

Background: Arterial hypertension (AH), metabolic syndrome (MS) and diabetes mellitus type 2 (DM2) are interrelated metabolic disorders. The aim of our study was to evaluate how the coexistence of MS or DM2 with AH influences arterial reactivity during cold pressor test (CPT). Methods: We studied 102 patients, 32 with AH (Group A), 38 with AH and MS (Group B) and 32 with AH and DM2 (Group C). All patients underwent full laboratory evaluation and measurement of systolic and diastolic blood pressure (SBP and DBP), heart rate (HR) and carotid-femoral pulse wave velocity (PWVc-f) before and during CPT. Results: During CPT PWVc-f, SBP, DBP and HR were increased significantly in all studied groups, but the change of PWVc-f and HR during CPT was significantly greater in group A compared to group C. On the contrary, the coexistence of MS or DM2 with AH does not alter the response of BP to CPT. Conclusion: The increase of CV risk resulting from the coexistence of MS or DM2 with AH, is best expressed by PWVc-f, while the change of the former and HR during CPT possibly reflects dysfunction of the autonomic nervous system.
