Presentation Transcript

  1. Cardiovascular Disease A. Palumbo 9th Grade Health

  2. The Cardiovascular System • Transports nutrients and removes waste from the body. • Supplies blood and oxygen to the body.

  3. The Cardiovascular System • Heart • Arteries • Veins • Lungs • Kidneys

  4. The Heart • Superior Vena Cava • Right and Left atrium • Right and left ventricle • Aorta • Pulmonary artery • Arteries • Supply the oxygen to the heart muscle

  5. Arteries and Veins • Arteries • Carry blood away from the heart • Oxygenated • Carries oxygen all parts of the body • Veins • Carry blood to the heart • Deoxygenated • Carries carbon dioxide and other waste

  6. Lungs and Kidneys • Lungs • Where the blood picks up oxygen once you inhale • Allows the release of Carbon dioxide once you exhale • Kidneys • Filters waste out of the blood

  7. What is Cardiovascular Disease? • Coronary Artery Disease (narrowing the arteries) • Heart attacks • Abnormal heart rhythms or arrhythmias • Heart failure • Heart valve disease • Heart muscle disease • Pericardial disease • Vascular Disease (blood vessels)

  8. Coronary Artery Disease • Atherosclerosis • Hardening of the arteries that provide vital oxygen and nutrients to heart • Could eventually cause a part of the heart muscle (myocardium) die off • Lack of blood flow.

  9. Abnormal heart Rhythms • Steady heart beats about 60-100 times a minute • Heart can get out of rhythm called arrhythmia • Produce uneven heart beats • Can change rate • Cause heart beat to be very slow or very fast

  10. Heart Failure • Does not mean heart has stopped working • Blood is not pumping as well as it should • Leads to water retention (swelling) and shortness of breath.

  11. Heart valve and heart muscle • A valve lies at each exit of the four chamber of the heart • On way • Insufficiency • Cardiomyopathies • Disease in heart muscle • Also called enlarged heart • Abnormally thick and enlarge • Causes weak blood flow

  12. Pericarditis • Inflammation of the lining surrounding the heart • Rare condition often caused by infection

  13. What happens during a heart attack? • Myocardial infarction • Myo-muscle • Cardial-heart • Infarction-death of tissue due to lack of blood supply • Plaque builds up in arteries supplying blood • Blood clots form around plaque and totally block the artery • This causes part of the muscle to be oxygen deprived and die • Causes permanent damage to heart muscle

  14. Signs and Symptoms of heart attack • Shortness of breath • Chest pains • Discomfort, pressure, heaviness • Below breast bone • Discomfort in arm, back, jaw, or throat • Sweating, dizziness • Nausea, vomiting • Extreme weakness • Rapid or irregular heart beats

  15. Test to diagnose a heart attack • ECG • EKG- can tell how much damage has occurred in heart muscle • Blood test • Look for Cardiac enzymes to indicate muscle damage • Cardiac catheterization • Cardiac cath • Can see direct visual of block artery

  16. Uncontrollable Risk factors • Male Sex • Older age • Family history of heart disease • Post- menopausal

  17. Controllable risk factors • Smoking • High cholesterol • High LDL “bad cholesterol” • Hypertension • High blood pressure • Physical inactivity • Obesity • Diabetes (uncontrolled) • Uncontrolled Stress and anger

  18. Prevention • Do not smoke • Controlled diet- EAT RIGHT • Improve cholesterol levels • Achieve and maintain healthy weight • Regular exercise- BE ACTIVE • 30-60 minutes most days of the week • Control Hypertension • Exercise and good diet • Manage Stress

  19. Statistics • Cardiovascular disease is the leading cause of death in both men and women in the US. • Heart failure is a major health problem in US affecting 5 million Americans. • The leading cause of hospitalization in people over 65

  20. Statistics Cont. • About eight out of 1,000 children are affected by congenital heart disease. • Coronary artery disease cause abut 1.2 million heart attacks each year. About 40 percent will die
