Presentation Transcript

  1. Cardiovascular Disorders

  2. Hypertension p671 • Ateriosclerosis • “silent killer” • Heart muscle can die due to lack of Oxygen • Increases chances of CVA: cerebral vascular accident

  3. Accumulation of plaque buildup on walls of arteries. arteriosclerosis Coronary Artery Disease

  4. Mycardial infarction Caused by an obstructured vessel in heart thrombus, embolus deprivation of oxygen (normally…body releases hypoxia induced factor which stimulates angiogenesis) If angiogenesis isn’t successful…part of heart dies Heart Attack

  5. Heart Attack Animation • http://www.healthcentral.com/cholesterol/understanding-cholesterol-13-115.html • http://www.medindia.net/animation/heart_attack.asp

  6. Inflammation of pericardial sac due to viral or bacterial infection Chest pain, interferes with heart movements Pericarditis

  7. One or both cusps of mitral valve stretches and bulges into left atrium during ventricular contraction Blood can regurgitate into the left atrium Palpitations, fatigue, anxiety, chest pains associated with arrhythmias (atrial fibrillation) that may progress Mitral Valve Prolapse

  8. Amyloid protein deposits into heart Causes chest pain, failure of cardiac muscles, disturbance of heart rhythm the deposits physically disrupt tissue architecture; some cases lead to cell death WHY? calcium ion concentration imbalances Ultrasound: echocardiogram can detect Familial Amyloidosis

  9. Transposition of Great Arteries
