How is smoking a factor associated with stroke?
5 answers
Smoking is a significant factor associated with stroke, especially in young individuals. Research indicates that smoking is positively linked to intracranial artery dissection (ICAD) in young patients, even after propensity score matching. Furthermore, smoking is recognized as a modifiable risk factor for stroke, with the risk being proportional to the amount of tobacco consumed. Studies have shown that smoking increases the risk of cardiovascular diseases, ultimately leading to stroke, with specific tendencies observed in stroke patients who smoke, such as the type of stroke and comorbidities. Additionally, smoking, especially at higher intensities, significantly raises the risk of different stroke subtypes, including intracerebral hemorrhages, cerebral infarctions, and subarachnoid hemorrhages, in both men and women.
