Independent factors of flow velocity indices in common carotid artery

Several parameters were used to investigate differences in aging rates influenced by cardiovascular risk factor. We sought to identify independent predictors modulating velocity indices in common carotid artery (CCA) from large population of normotensive and hypertensive to predict health risk. We s...
