Cerebrovascular patients can not smoke, smoking is very harmful to the brain. Smoking is very harmful to all organs of the body, and in the cerebral vasculature, it mainly affects the endothelium, which is damaged by long-term smoking, leading to atherosclerosis and the appearance of carotid plaques. And plaque generation in addition to hypertension, diabetes, hyperlipidemia, a very important risk factor is smoking. For example, some patients do not have three highs, i.e., no hypertension, diabetes, or hyperlipidemia, but they also have a lot of plaques because they have a long history of smoking. Therefore, smoking and carotid atherosclerosis, intracerebral atherosclerosis, including cardiovascular disease are closely related, especially in addition to smoking, but also a family history of hypertension, diabetes, making the probability of cardiovascular disease greatly increased. So smoking is very harmful to the cerebrovascular, especially for people who smoke more than 1 pack a day, the probability of disease is very high, so patients with cerebrovascular disease should not smoke.
