Toe Brachial Pressure Index as Alternative Method to Correlate Arteriosclerotic Disease in Type 2 Diabetes.

AIM

To investigate the association between the ankle brachial pressure index and toe brachial pressure index with the findings of carotid Doppler ultrasonography in patients with diabetes and coronary ischaemic disease.

METHODS AND RESULTS

The objective was to evaluate the relationship between insulin resistance and serum homocysteine in subjects with polycystic ovarian syndrome (PCOS).

CONCLUSION

We studied 81 type 2 diabetic patients, with established cardiovascular disease, consecutively admitted to our outpatient clinic in the Division of Diabetes of La Paz Hospital. We collected clinic and demographic data, ABI and TBI were measured and at the same time a carotid Doppler ultrasound was performed. Multiple linear regression analysis was used to investigate the association of ABI and TBI with carotid disease. We found a negative correlation between TBI and internal carotid artery peak systolic velocity (ICA PSV) (r = -0,300, p= 0,007), common carotid artery resistance index (CCA RI) (r = -0,232, p= 0,038) and intima-media thickness (IMT) (r -0,236, p=0,035). Toe blood pressure and ICA PSV showed an inverse association (r=- 0,226, p=0,042). Adjusting for clinical and demographic characteristic, only low TBI index is associated with a higher ICA PSV.
