Ambulatory arterial stiffness index in diabetic patients
ABSTRACT Background The ambulatory arterial stiffness index (AASI), derived from 24 h ambulatory blood pressure monitoring (ABPM) can be a good indicator of arterial stiffness. Aim To assess the correlation between AASI and brachial-ankle pulse wave velocity (baPWV), ankle-brachial index (ABI) and...

| Sumario: | ABSTRACT Background The ambulatory arterial stiffness index (AASI), derived from 24 h ambulatory blood pressure monitoring (ABPM) can be a good indicator of arterial stiffness. Aim To assess the correlation between AASI and brachial-ankle pulse wave velocity (baPWV), ankle-brachial index (ABI) and cardio-ankle vascular index (CAVI) in patients with type 2 diabetes mellitus without hypertension. Material and Methods Cross sectional study in 28 diabetic patients aged 49 ± 7 years (40% women). AASI was calculated as 1 minus the regression slope of diastolic on systolic blood pressure, using ABPM data. ABPM was measured in the arm using an oscillometric device. ABI was calculated as the ratio between ankle and brachial systolic blood pressure. CAVI was derived from pulse wave velocity using the Vasera VS-1000 device. Correlations were calculated using a bivariate Spearman correlation. Results The mean values for AASI, ABI, baPWV and CAVI were 0.39 ± 0.14, 1.14 ± 0.09, 15.15 ± 2.71 m/s and 7.60 ± 1.90, respectively. There was a significant negative correlation between AASI and ABI (r = -0.491, p < 0.01). Conclusions In these diabetic patients, there was an association between AASI, an arterial stiffness marker and ABI, an indicator for the presence of atherosclerosis. |
