A sex specific approach of ophthalmic and middle cerebral arteries Doppler in smokers

Abstract Vascular dysfunctions can progress and lead to stroke and cardiovascular disease, especially in smokers. The presence of particular vascular changes according to sex has been described and they can be identified by the Doppler method. This study evaluated Doppler velocimetry parameters of t...
