  3. Over-view of Unit 5 • Any issues that you came across in Unit 5 that I need to address?

  4. Unit 6 Expectations

  5. Background Information Pg 439

  6. Circulatory system • What is the primary function of the circulatory system? • What are the components of the vascular system? Pg 93

  7. The primary function of the circulatory system is to nourish the visceral with nutrients and oxygen • The components of the vascular circuit include the lungs (pulmonary), the peripheral vessels (mainly iliac vessels), the visceral organs (digestive and urinary system) and the cephalic

  8. Coronary Artery Disease • Description of CAD? Pg 441

  9. CAD Coronary artery disease: A condition involving the arteries that supply the myocardium, in which the arteries become narrowed due to atherosclerotic deposits over time, causing temporary cardiac ischemia and eventually heart attack Pg 441

  10. Etiology of CAD • Difference btn atheroma vs. thrombus? Pg 80

  11. Etiology of CAD • Atheroma- mass of fibro-fatty material, cells and lipids • Thrombus- A blood clot attached to the interior wall of the blood vessel, often causing vascular obstruction Pg 80

  12. Etiology of CAD • A combination of the endothelial damage and the atheroma is called a ______________ Pg 80

  13. Etiology of CAD • A combination of the endothelial damage and the atheroma is called a Plaque Pg 442

  14. Etiology of CAD • List the consequences of atherosclerosis in different tissues Pg 78

  15. Etiology of CAD • List the consequences of atherosclerosis • Heart: Partial occlusion Angina pectoris • Total occlusion MI • Brain: Partial occlusion Ischemic attack • Total occlusion CVA • Vessels: Aorta Aneurysm • Legs PVD • (Gangrene and amputation) Pg 443

  16. Sites of MI • State the sites of MI in men Pg 448

  17. Sites of MI Pg 448

  18. Diagnosis of MI a) Are the MI sites the same in men and in women? b) How is MI diagnosed? Pg 447

  19. Diagnosis of MI • Thorough medical history • Electrocardiogram changes • Chest radiographic films • Changes in enzyme levels e.g. CPK, LDH, AST, Pg 447

  20. Patient education of MI • State patient education is used in MI? Pg 447

  21. Patient education of MI • State patient education is used in MI? • Call 9ll for emergency • Chew 325g aspirin tablets • Defibrillation where possible Pg 447

  22. Treatment of MI • What is the time window from the onset of the infarction before permanent damage results? Pg 450

  23. Treatment of MI • What is the time window from the onset of the infarction before permanent damage results? Six hours Pg 450

  24. Cardiac arrest • ___________ __is a sudden, unexpected cessation of cardiac activity Pg 79

  25. Cardiac arrest • _Cardiac arrest is a sudden, unexpected cessation of cardiac activity Pg 79

  26. Cardiac arrest • What measures are initiated to reverse a cardiac arrest? Pg 79

  27. Cardiac arrest • What measures are initiated to reverse a cardiac arrest? • CPR must be instituted within 4 to 6 minutes of cardiac arrest by a trained, advanced life-support personnel. Cardiac drugs including adrenaline, dobutamine and antiarrhythmic drugs must be administered. • In addition, therapeutic hypothermia can be tried Pg 79

  28. Hypertension • Describe the types of hypertension Pg 25

  29. Hypertension • What is the first indication of hypertension? Pg 25

  30. Hypertension • What is the first indication of hypertension? Elevated blood pressure readings -- systolic reading greater than 140 mm Hg and diastolic reading greater than 90 mm Hg indicate hypertension Pg 25

  31. Hypertension • Discuss the treatment of hypertension Pg 452

  32. Hypertension • Discuss the treatment of hypertension • Diuretics to reduce circulating blood volume • Beta-adrenergic blockers to slow heartbeat • Vasodilators to dilate vessels • Angiotensin-converting enzyme (ACE) inhibitors to produce vasodilation and increase renal blood flow

  33. What disease is characterized by the following symptoms? Pg 454
