Smoking is also not recommended after recovering from a cerebral infarction. Smoking increases the risk of recurrence of cerebral infarction. The chemicals in cigarettes can aggravate the damage of cerebral arteries, making plaques easy to rupture and bleed, or fall off and block small arteries, thus inducing new acute cerebral infarction. In addition, long-term smoking tends to reduce blood flow to the brain, and the reduction of prostacyclin also tends to lead to vasoconstriction and platelet aggregation, resulting in thrombotic events. At the same time, smoking can also cause changes in blood pressure, which can have an impact on the cardiovascular system. Therefore, it is suggested that it is best not to smoke after cerebral infarction, and should follow the doctor’s advice to take aspirin, atorvastatin and other drugs regularly. At the same time, abstain from alcohol, moderate exercise, light diet, and do a good job of lifestyle improvement, so as to be able to prevent the recurrence of cerebrovascular disease.
