1. NON-COMMUNICABLE DISEASES: CARDIOVASCULAR

3. Target: I will be able to describe symptoms of cardiovascular diseases Pg. 57 Non-communicable Disease: a disease that is non- infectious Lifestyle Disease: A disease associated with the way a person lives. Examples: Cardiovascular disease, obesity, type 2 diabetes

4. Cardiovascular Disease (CVD): Diseases which affect the heart and circulatory system 610,000 people die of heart disease in the US every year–that’s 1 in every 4 deaths.

6. Risk Factors for Cardiovascular Diseases: 1. Heredity- heart disease runs in family 2. Ethnicity- African Americans are 2 times more likely to develop CVD 3. Gender- males have a greater risk of heart disease and stroke Heart attacks are the #1 killer of women

7. 4. Age- CVD increases with age; especially after 45 5. Environment- smog, tobacco smoke, and stress 6. Behavior- physical inactivity, smoking, alcohol use, bad food choices (high fat/sodium), obesity Make healthy choices now to reduce risk of CVD and stroke later

8. Types of Cardiovascular Diseases: 1. Hypertension: high blood pressure (the force of blood flow against the artery walls) The more blood your heart pumps and the narrower your arteries, the higher your BP May not show symptoms- aka “the silent killer” Leads to heart attacks and strokes Controlled by: eating well (reducing fats/salts), lose weight/exercise, medication

10. 2. Arteriosclerosis: Hardening of the arteries that restricts blood and oxygen to organs One type is- Atherosclerosis: Plaque (fat deposits) build up on the walls of the arteries because of poor food choices (high fat/cholesterol). If a blood clot forms, it can stop blood flow, causing a heart attack or stroke

11. Atherosclerosis Animation

12. 3. Congestive Heart Failure: a slow gradual weakening of the heart from years of overwork Blood moves though the body at a slower rate and pressure in the heart increases (heart size increases) Kidneys respond by causing the body to retain (hold onto) water and salt (heart gets bigger)

13. Conjestive Heart Failure Animation

14. Heart Attack: Blood flow to part of the heart is blocked by a clot and oxygen supply is cut off Symptoms: Angina Pectoris (pain and tightening in the chest), pain down arms, pain in jaw, neck, upper abdomen, or back, nausea, sweating, vomiting, and shortness of breath

17. Heart Attack Animation

18. Stroke: an interruption of the flow of blood to any part of the brain Brain cells are blocked or broken and deprived of oxygen and die within minutes Most likely causes: uncontrolled hypertension and atherosclerosis

19. Symptoms: sudden weakness/numbness in face, arm, or leg on one side of the body, loss of speech/ trouble speaking, trouble understanding, loss of vision is one eye, dizziness, unsteadiness, or sudden falls

21. FAST- Face drooping, Arm weakness, Speech difficulty, Time to call 911 Summary
