Study Notes
Heart Function and Importance
- The heart beats around 2.5 billion times during an average lifetime, pumping blood throughout the body.
- The constant movement of blood is critical to ensuring proper bodily function, transporting essential compounds and removing metabolic waste products.
Cardiovascular Disease (CVD)
- CVD is a general term that includes conditions affecting the heart and blood vessels, such as coronary artery disease, high blood pressure, heart attack, and heart failure.
- CVD is the leading cause of death for men, women, and people of most racial and ethnic groups in the United States.
Risk Factors for Heart Disease
- Uncontrollable risk factors: increased age, family history, and type 1 diabetes.
- Controllable risk factors:
- Dietary choices: high sodium, sugar, saturated fats, trans fats, cholesterol, and low fiber intake.
- Lifestyle choices: lack of exercise, tobacco use, and alcohol use.
- Chronic stress.
- Environmental factors: exposure to second-hand smoke, air pollution, and extreme heat.
Cardiovascular Fitness
- The Harvard Step Test measures a person's ability to recover after strenuous exercise.
- Lower peak heart rate and faster recovery time indicate good cardiovascular health.
