Assessment of intima-media complex in carotid, femoral and right subclavian arteries for early investigation of atherosclerosis in HIV-infected patients

“…On Figures 2 and 4, it is possible to observe that all the measurements remain grouped at a single level, with the exception of the measurement at the origin of the right subclavian artery. As a variation < 0.1 mm is adopted as a reference for the acceptance of a clinical threshold of agreement (23)(24)(25)(26) , one observes, in the present study, that the only clinically significant difference was the measurement at the origin of the right subclavian artery. For such result, all comparisons between automatic and manual measurements in the HIV patients and control groups were taken into consideration, adopting the mean automatic measurement on the RCC as a standard.…”

“…In the comparison between measurements on LCC in HIV patients and control groups, as shown on Figures 3 and 5, it is possible to observe that the mean automatic measurement value was closer to the minimum manual measurement value and more distant from the maximum manual measurement value, but, considering the variation of < 0.1 mm (23)(24)(25)(26) , there was no clinical relevance in such a variation in the present study.…”

Efeito da terapia antirretroviral e dos níveis de carga viral no complexo médio-intimal e no índice tornozelo-braço em pacientes infectados pelo HIV

“…The ankle-brachial index (ABI) is a non-invasive method with high predictive value for peripheral arterial disease, and it is significantly associated with the risk of cardiovascular mortality; its cost is low, and it has been validated in the general population 15,33 . Reduction of ABI to values lower than 0.9 is associated with the significant increase in cardiovascular risk, especially by AMI and stroke, independently of other risk factors 34,35 .…”
