Deep dives
Total cholesterol and Stroke Risk
Having higher levels of atherogenic cholesterol increases the risk of stroke. Lower cholesterol levels are beneficial for reducing stroke risk. Lower cholesterol should be achieved through lifestyle changes, diet, and medication if necessary.
High Blood Pressure and Stroke Risk
High blood pressure is one of the major modifiable risk factors for stroke. Elevated blood pressure increases the risk of stroke progressively with higher levels. Lifestyle changes, dietary adjustments, and medications can help in managing high blood pressure and reducing stroke risk.
Body Composition and Stroke Risk
There is a positive relationship between stroke and obesity. Overweight individuals have a 22% greater risk of stroke, while obese individuals have a 64% increased risk. Managing body composition through lifestyle changes, dietary modifications, and possible medications can help lower stroke risk.
Blood Sugar Control and Stroke Risk
Diabetes more than doubles the risk of stroke. Poor blood sugar control increases susceptibility to atherosclerosis and other risk factors. Duration of diabetes significantly impacts the risk, with each year of diabetes duration contributing to a 3% increase in risk for an ischemic stroke.
Atrial Fibrillation as a Modifiable Risk Factor
Atrial fibrillation increases the risk of ischemic stroke four to fivefold. It can be managed by addressing contributing factors like obesity, metabolic syndrome, sleep apnea, and alcohol use. Getting atrial fibrillation under control is crucial in reducing the risk of stroke.
Physical Inactivity and Stroke Risk
Engaging in regular physical activity can significantly reduce the risk of stroke. Individuals meeting physical activity guidelines have a 25 to 30% lower risk of stroke and stroke-related mortality. Maintaining an active lifestyle helps in preventing strokes and other cardiovascular issues as people age.
Exercise as a Powerful Tool in Reducing Stroke Risk
Exercise plays a crucial role in reducing the risk of stroke through both direct and indirect mechanisms. Directly, exercise improves body composition, blood pressure, type two diabetes management, and blood lipids. Indirectly, it optimizes these risk factors by promoting a healthier lifestyle. Research comparing exercise to anti-hypertensive medications showed that exercise significantly reduced blood pressure, making it a powerful tool in stroke prevention. Additionally, dietary patterns rich in fruits and vegetables have shown a dose-dependent relationship in reducing stroke risk.
The Role of Exercise in Stroke Rehab
In stroke rehabilitation, early mobilization and exercise initiation are recommended to regain or surpass pre-stroke activity levels. The American Heart Association suggests starting physical activity soon after a stroke, but the exact timing remains controversial. Studies like the Avert trial explored very early mobilization within 24 hours after a stroke, indicating its feasibility and safety. Resistance training, while beneficial for improving muscular function and spasticity post-stroke, lacks standardized protocols in stroke rehab settings. Optimizing modifiable risk factors like blood pressure, cholesterol, and physical activity can significantly reduce the risk of stroke and its associated disabilities.
May is National Stroke Awareness Month and on this podcast, Drs. Baraki and Feigenbaum discuss risk factors for stroke, how exercise can help, and more.
