Abstract

Analysis of flow-mediated vasodilation (FMV) of the brachial artery by use of ultrasound allows assessing endothelial function, and provides pathophysiological, diagnostic and prognostic information. This systematic review was aimed at assessing the literature level of evidence of the predictive capacity of endothelial function, measured through brachial artery FMV by use of ultrasound, regarding cardiovascular events in individuals with atherosclerosis. The MEDLINE, SCIELO and LILACS databases were searched, and prospective cohort studies on human beings about the prognostic value of endothelial function, measured by use of brachial artery FMV in individuals with peripheral or coronary atherosclerosis, were selected. Studies with clear methodological biases were excluded. The final selection consisted of 15 studies. Of the 13 studies that on univariate analysis showed statistical significance of the FMV method to predict cardiovascular events, 12 showed independent predictive capacity on multivariate analysis. None of the studies reviewed described the incremental predictive value of FMV to the traditional predictive models, such as the Framingham score. Results of three studies have suggested that the method adds prognostic value to isolated markers such as ankle-brachial index (ABI), diabetes, and high-sensitivity C-reactive protein (hsCRP). In conclusion, brachial artery FMV predicts cardiovascular risk, but its incremental predictive value to clinical prognostic models has not been established. In addition, solid evidence supporting its use in routine clinical practice to predict cardiovascular risk still lacks.

CRD has determined that this article meets the DARE scientific quality criteria for a systematic review.
