Cardiovascular disease (CVD) is a leading cause of death worldwide. The World Health Organization reports that 17.9 million people died from CVD in 2016, accounting for 31% of all deaths globally. The risk factors for CVD include hypertension, high cholesterol, smoking, obesity, and a sedentary lifestyle. Exercise has long been touted as a key component in the prevention and management of CVD. In this article, we will review the evidence supporting exercise as medicine in the prevention and management of CVD.

Exercise and Cardiovascular Health

Exercise has numerous benefits for cardiovascular health. Regular physical activity has been shown to lower blood pressure, improve lipid profiles, reduce inflammation, and improve glucose metabolism. Exercise also helps maintain a healthy weight, which is a key factor in reducing the risk of CVD.

Exercise and Hypertension

Hypertension, or high blood pressure, is a major risk factor for CVD. Exercise has been shown to reduce blood pressure in both normotensive and hypertensive individuals. The American College of Cardiology and the American Heart Association recommend 90-150 minutes of moderate-intensity exercise per week for individuals with hypertension. Exercise may also reduce the need for antihypertensive medication in some individuals.

Exercise and Lipid Profiles

High levels of low-density lipoprotein (LDL) cholesterol are a major risk factor for CVD. Exercise has been shown to improve lipid profiles by increasing high-density lipoprotein (HDL) cholesterol and reducing LDL cholesterol. Aerobic exercise has been shown to be particularly effective in improving lipid profiles.

Exercise and Glucose Metabolism

Type 2 diabetes is a major risk factor for CVD. Exercise has been shown to improve glucose metabolism by increasing insulin sensitivity and reducing insulin resistance. The American Diabetes Association recommends at least 150 minutes of moderate-intensity exercise per week for individuals with type 2 diabetes.

Exercise and Cardiovascular Rehabilitation

Exercise is an important component of cardiovascular rehabilitation. Cardiovascular rehabilitation is a comprehensive program designed to help individuals with CVD recover and regain their health. Exercise is an important component of cardiovascular rehabilitation because it helps improve cardiovascular fitness, reduces the risk of future cardiac events, and improves overall health and quality of life.

Exercise and Cardiac Rehabilitation

Cardiac rehabilitation is a specific type of cardiovascular rehabilitation designed for individuals who have experienced a cardiac event, such as a heart attack or coronary artery bypass surgery. Cardiac rehabilitation typically includes exercise, education, and support to help individuals recover and prevent future cardiac events. Exercise is a key component of cardiac rehabilitation because it helps improve cardiovascular fitness and reduce the risk of future cardiac events.

Exercise and Heart Failure

Heart failure is a common condition in which the heart is unable to pump enough blood to meet the body’s needs. Exercise has been shown to be effective in the management of heart failure. Exercise can help improve exercise capacity, reduce symptoms, and improve quality of life in individuals with heart failure. The American Heart Association recommends at least 150 minutes of moderate-intensity exercise per week for individuals with heart failure.

Exercise and Atrial Fibrillation

Atrial fibrillation (AFib) is a common arrhythm in which the heart beats irregularly. Exercise has been shown to be effective in the management of AFib. Regular physical activity can help reduce the frequency and severity of AFib episodes, improve cardiovascular fitness, and improve overall health and quality of life. The American Heart Association recommends at least 150 minutes of moderate-intensity exercise per week for individuals with AFib.

Exercise and Stroke

Stroke is a serious condition in which blood flow to the brain is disrupted, leading to brain damage and potentially permanent disability. Regular physical activity has been shown to reduce the risk of stroke. Exercise can also help improve cardiovascular fitness, reduce the risk of other risk factors for stroke (such as hypertension and diabetes), and improve overall health and quality of life.

Exercise and Peripheral Artery Disease

Peripheral artery disease (PAD) is a condition in which the arteries in the legs and feet become narrowed or blocked, leading to reduced blood flow and potentially serious complications. Exercise has been shown to be effective in the management of PAD. Regular physical activity can help improve walking ability, reduce symptoms, and improve overall health and quality of life in individuals with PAD.

Exercise and Mental Health

Exercise has numerous benefits for mental health, including reducing symptoms of depression and anxiety, improving self-esteem, and reducing stress levels. These mental health benefits of exercise may be particularly important for individuals with CVD, as depression and anxiety are common in individuals with CVD and can have negative effects on cardiovascular health.

Exercise Prescription for CVD

The American College of Cardiology and the American Heart Association recommend at least 150 minutes of moderate-intensity exercise per week for individuals with CVD. This can include activities such as brisk walking, cycling, swimming, or dancing. Individuals with CVD should also engage in resistance training at least two days per week, focusing on major muscle groups.

It is important for individuals with CVD to work with their healthcare providers to develop an exercise prescription that is appropriate for their individual needs and abilities. This may include modifications to the exercise program based on the individual’s age, fitness level, and any comorbidities they may have.

Conclusion

Exercise is an effective and important component of the prevention and management of CVD. Regular physical activity can help improve cardiovascular health, reduce the risk of future cardiac events, and improve overall health and quality of life. It is important for individuals with CVD to work with their healthcare providers to develop an exercise prescription that is appropriate for their individual needs and abilities. By incorporating exercise into their daily routine, individuals with CVD can improve their cardiovascular health and reduce their risk of future cardiac events.
