Myocardial Infarction

  1. 1. Number One Killer Of Both Men And Women In The US Each Year<br />Myocardial Infarction <br />Grace Kirchgessner<br />
  2. 2. Myocardial Infarction(mi″o-kahr´de-al in-fahrk´shun)ABBR: MI<br />Myocardial Infarction is commonly known as a heart attack. "Myo" means muscle, "cardial" pertains to the heart, and "infarction" means death of tissue due to lack of blood supply. <br />The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.<br />A heart attack occurs when blood vessels that supply blood to the heart are blocked, preventing enough oxygen from getting to the heart. The heart muscle then dies or becomes permanently damaged. <br />Dead Muscle<br />
  3. 3. Coronary Arteries<br />Coronary arteries run along the surface of the heart. These vessels supply oxygen-rich blood and nutrients to the heart. Over time, fatty deposits can build up in blood vessel walls (atherosclerosis). Plaque can cause hardening of the arterial walls and narrowing of the inner channel, as a result, restricting blood flow. A heart attack may occur if not enough oxygen-containing blood can flow through this blockage. This is more likely to happen when you are exercising.<br />The plaque itself develops cracks or tears. Blood platelets stick to these tears and form a blood clot (thrombus). A heart attack can occur if this blood clot completely blocks the passage of oxygen-rich blood to the heart. This is the most common cause.<br />
  4. 4. A Look Inside Myocardial Infarction<br />
  5. 5. How Is a Heart Attack Treated? <br />Early treatment for a heart attack can prevent or limit damage to the heart muscle. Certain treatments usually are started right away if a heart attack is suspected, even before the diagnosis is confirmed. These include:<br /><ul><li>Aspirin to thin your blood and prevent further blood clotting
  6. 6. Nitroglycerin to reduce your heart's workload and improveblood flow through the coronary arteries
  7. 7. Treatment for chest pain
  8. 8. Oxygen Therapy</li></ul>The two main treatments are "clot-busting" medicines and angioplasty, a procedure used to open blocked coronary arteries. In severe cases, coronary artery bypass surgerymay be necessary. Although, not your typical treatment Niacin (Vitamin B3) is highly effective at increasing your HDL (good cholesterol) and lowering your LDL (bad cholesterol). It has been used for years and clinical studies have shown great results. Niacin is a proven treatment for many things such as, the cardiovascular system, blood pressure, blood sugar, circulation, diabetes, nervous system, arthritis, depression, anxiety, the digestive system, and much more.<br />
  9. 9. Angioplasty<br />
  10. 10. Symptoms<br />Chest pain is a major symptom of heart attack. Pain may be felt in only one part of your body, or it may move from your chest to your arms, shoulder, neck, teeth, jaw, belly area, or back. The pain can be severe or mild. It can feel like:<br /><ul><li>A tight band around the chest
  11. 11. Bad indigestion
  12. 12. Something heavy sitting on your chest
  13. 13. Squeezing or heavy pressure
  14. 14. The pain usually lasts longer than 20 minutes. </li></ul>Other symptoms of a heart attack include:<br /><ul><li>Anxiety
  15. 15. Cough
  16. 16. Fainting
  17. 17. Light-headedness, dizziness
  18. 18. Nausea or vomiting
  19. 19. Palpitations (feeling like your heart is beating too fast or irregularly)
  20. 20. Shortness of breath
  21. 21. Sweating, which may be extreme</li></ul>Some people (the elderly, people with diabetes, and women) may have little or no chest pain. Or, they may experience unusual symptoms (shortness of breath, fatigue, weakness). A "silent heart attack" is a heart attack with no symptoms (ischemia).<br />
  22. 22. How To Prevent A MI<br />To prevent a heart attack:<br />Keep your blood pressure, blood sugar, and cholesterol under control.<br />Don't smoke.<br />Consider drinking 1 to 2 glasses of alcohol or wine each day. Moderate amounts of alcohol mayreduce your risk of cardiovascular problems. However, drinking larger amounts does more harm than good.<br />Eat a low-fat diet rich in fruits and vegetables and low in animal fat.<br />Eat fish twice a week. Baked or grilled fish is better than fried fish. Frying can destroy some of the health benefits.<br />Exercise daily or several times a week. Walking is a good form of exercise. Talk to your doctor before starting an exercise routine.<br />Lose weight if you are overweight.<br />
