  1. 1. Coronary Heart Diseases<br />
  2. 2. Coronary Heart Diseases - Causes<br />Diet<br />Stress<br />Smoking<br />
  3. 3. Atherosclerosis<br />Atherosclerosis is the hardening of the arteries due to fat deposition.<br />
  4. 4. Atherosclerosis<br />High blood pressure and chemicals in tobacco smoke can cause damage to the endothelium of blood vessels.<br />Atherosclerosis usually occurs in arteries rather than veins.<br />This is because the blood flows under high pressure in arteries which can cause damage to the endothelium.<br />
  5. 5. Atherosclerosis<br />
  6. 6. Problems caused by atherosclerosis<br />Blood accumulates behind the plaque and the artery wall bulges and will eventually become weakened.<br />The weakened artery may split open leading to internal bleeding (hemorrhage).<br />
  7. 7. Problems caused by atherosclerosis<br />Bleeding from capillaries into the brain results in stroke.<br />
  8. 8. Chest Pain<br />Chest pain or discomfort occurs when the heart is not getting enough oxygen because of reduced blood flow to the cardiac muscle.<br />This is a common symptom of coronary heart disease.<br />
  9. 9. Thrombosis<br />Clot that forms in a blood vessel.<br />Platelets come into contact with the plaque and the clotting process begins.<br />
  10. 10. Coronary Thrombosis<br />A clot that gets stuck in a coronary artery is known as a coronary thrombosis.<br />
  11. 11. What can we do?<br />Important to react quickly.<br />Call an ambulance.<br />Give the person two full strength aspirin tablets.<br />
  12. 12. Stroke<br />A stroke is caused by an interruption to the normal blood supply in an area of the brain.<br />This may be caused due to the breaking of blood vessels (due to high BP) or due to a blockage to the blood vessels supplying to the brain.<br />
  13. 13. Symptoms of stroke<br />dizziness<br />confusion<br />slurred speech<br />blurred vision<br />numbness<br />paralysis<br />
  14. 14. What can we do to prevent CVD?<br />Healthy lifestyle<br />Don’t smoke<br />Exercise<br />Say no to alcohol<br />Avoid stress<br />
