  1. 1. Cardiovascular Disease
  2. 2. CVD <ul><li>Heart diseases are responsible for more death than any other cause in UK. </li></ul><ul><li>Around 20% of the death are caused by cardio vascular diseases. </li></ul>
  3. 3. Atherosclerosis <ul><li>Atherosclerosis is the hardening of the arteries due to fat deposition. </li></ul>
  4. 4. Plaque <ul><li>A fatty deposit hardened by calcium salts and fibrous tissue which may form on the lining of an artery. </li></ul><ul><li>Plaques formed in coronary artery (supplying blood to the walls of heart) and carotid artery (supplying blood to the head) are more dangerous. </li></ul>
  5. 5. Atherosclerosis <ul><li>High blood pressure and chemicals in tobacco smoke can cause damage to the endothelium of blood vessels. </li></ul><ul><li>Atherosclerosis usually occurs in arteries rather than veins. </li></ul><ul><li>This is because the blood flows under high pressure in arteries which can cause damage to the endothelium. </li></ul>
  6. 6. Atheroma <ul><li>The damage in the endothelium attracts white blood cells. </li></ul><ul><li>Chemicals, especially cholesterol, is deposited in the area and lead to the formation of a fatty deposit called atheroma. </li></ul><ul><li>Fibrous tissue and calcium salts also build up around the atheroma, turning it into a hardened plaque. </li></ul><ul><li>The part of the artery wall hardens and becomes less elastic. </li></ul><ul><li>This condition is called atherosclerosis . </li></ul>
  7. 7. Atherosclerosis
  8. 8. Problems caused by atherosclerosis <ul><li>Blood accumulates behind the plaque and the artery wall bulges and will eventually become weakened. </li></ul><ul><li>This is known as aneurysm . </li></ul><ul><li>The weakened artery may split open leading to internal bleeding ( hemorrhage ). </li></ul>
  9. 9. Problems caused by atherosclerosis <ul><li>Increase in blood pressure can damage organs such as kidneys, eyes and brain. </li></ul><ul><li>If the blood pressure increases well beyond normal, more materials will be lost through urine. </li></ul><ul><li>Increase in blood pressure can cause damage to the capillaries of the eye and can lead to blindness. </li></ul>
  10. 10. Problems caused by atherosclerosis <ul><li>Bleeding from capillaries into the brain results in stroke. </li></ul>
  11. 11. Angina <ul><li>Chest pain or discomfort that occurs when the heart isn't getting enough oxygen because of reduced blood flow to the cardiac muscle. </li></ul><ul><li>Usually the result of atherosclerosis and is a symptom of coronary heart disease. </li></ul>
  12. 13. Angina can be prevented by <ul><ul><li>eating a low-fat diet </li></ul></ul><ul><ul><li>taking regular exercise </li></ul></ul><ul><ul><li>losing weight and </li></ul></ul><ul><ul><li>not smoking </li></ul></ul><ul><li>Symptoms of angina can be reduced with the usage of drugs which will dilate blood vessels. </li></ul><ul><li>Heart bypass surgery may be required in serious conditions. </li></ul>
  13. 14. Thrombosis <ul><li>Clot that forms in a blood vessel. </li></ul><ul><li>Platelets come into contact with the plaque and the clotting process begins. </li></ul>
  14. 15. Coronary Thrombosis <ul><li>A clot that gets stuck in a coronary artery is known as a coronary thrombosis. </li></ul>
  15. 16. What can we do? <ul><li>Important to react quickly. </li></ul><ul><li>Call an ambulance. </li></ul><ul><li>Give the person two full strength aspirin tablets. </li></ul>
  16. 17. Stroke <ul><li>A stroke is caused by an interruption to the normal blood supply in an area of the brain. </li></ul><ul><li>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. </li></ul>
  17. 18. Symptoms of stroke <ul><li>dizziness </li></ul><ul><li>confusion </li></ul><ul><li>slurred speech </li></ul><ul><li>blurred vision </li></ul><ul><li>numbness </li></ul><ul><li>paralysis </li></ul>
