Key result
Lifelong exercise reduces cardiovascular risk but may acutely increase stroke risk during or after exertion.
Why the study?
While lifelong exercise reduces cardiovascular and cerebrovascular risk, a complex interaction exists whereby the risk of ischemic or hemorrhagic stroke may acutely increase during or immediately following exercise.
This review highlights the complex relationship between exercise and stroke, noting that while long-term exercise is protective, there may be an acute increase in stroke risk during or immediately after exertion.

Supports lifelong exercise promotion for CVD prevention; leaves open acute stroke risk during exertion pending prospective data.
Ischemic heart disease and stroke are the number 1 and number 2 causes of death worldwide, respectively. A lifelong commitment to exercise reduces the risk of these adverse events and is also associated with several cardiometabolic improvements, including reductions in blood pressure, cholesterol, and inflammatory markers, as well as improved glucose control. Routine exercise also reduces the risk of developing comorbidities that increase the risk of cardiovascular or cerebrovascular disease. While the benefits of a lifelong commitment to exercise are well documented, there is a complex interaction between exercise and stroke risk, such that the risk of ischemic or hemorrhagic stroke may increase acutely during or immediately following exercise. In this article, we discuss the physiological responses to different types of exercise, as well as the determinants of resting and exertional cerebrovascular perfusion, and explore the complex interaction between atrial fibrillation, exercise, and stroke risk. Finally, we highlight the increased risk of stroke during different types of exercise, as well as factors that may alleviate this risk.

Edward et al. (2022) conducted a review in Stroke and cerebrovascular disease. Exercise was evaluated. Lifelong exercise reduces the risk of cardiovascular and cerebrovascular disease, but the risk of ischemic or hemorrhagic stroke may increase acutely during or immediately following exercise.
