Cardiovascular system

  1. 1. Cardiovascular SystemMedical ProceduresDiagnostic imagingclinical lab tests<br /> Robert Adams <br />Biology 120 <br />
  2. 2. Clinical Lab testCardiac enzymes<br />Blood test that allows the doctor to use the pattern of enzyme release after myocardial infarction (heart attack) to diagnose condition.<br />One of the best markers for revealing whether or not a heart attack has taken place and asses the degree of myocardial damage.<br />Blood test to determine the level of enzymes specific to heart muscles present in the blood.<br />
  3. 3. Cardiac Enzymes<br />Creatine Phosphokinase (CPK)<br />Takes 3-4 days to return to normal in blood stream.<br />
  4. 4. Cardiac Enzymes<br />Lactate Dehydrogenase (LDH)<br />Use has been superseded by the use of Troponin.<br />
  5. 5. Cardiac Enzymes<br />Glutamic Oxaloacetic Transaminase (GOT)<br />
  6. 6. Cardiac Enzymes<br />Troponin<br />Rises 6 to 8 hours after heart attack.<br />Takes 10 days to return to normal.<br />
  7. 7. Cardiac Enzymes<br />Myoglobin<br />Protein rapidly released after heart attack.<br />Useful in early diagnosis.<br />
  8. 8. Cardiac Enzymes<br />Test reveals severity of heart attack.<br />Determines and detects injury to the heart muscle because blood enzymes change in response to myocardial infarction.<br />
  9. 9. Cardiac Enzymes<br />Not Useful In Patients with…<br />Heavy alcohol use<br />Recent heavy exercise<br />Recent serious injury<br />Recent CPR or defibrillation<br />Kidney failure<br />Prescription to cholesterol medications<br />
  10. 10. Diagnostic imagingcardiac scan <br />Cardiac scan or Cardiac CT (Computed Tomography) scan<br />
  11. 11. Cardiac Scan<br />Patient is given radioactive thallium or iodine based dye intravenously.<br />Scanning equipment is then used to visualize the heart.<br />X ray machine moves around body in circle taking pictures of heart.<br />The computer then makes a 3d image of the heart using the pictures.<br />
  12. 12. Cardiac Scan<br />USES <br />To detect coronary artery disease or build up of plaque in coronary arteries.<br />To detect problem with heart function and heart valves.<br />To detect aneurysms and pulmonary embolism.<br />To detect pericardial disease.<br />
  13. 13. Cardiac Scan<br />Patients should not eat 4 hrs prior to scan.<br />Patients should avoid caffeine consumption before scan.<br />There is a small chance of scan causing cancer in people under the age of 40 due to the radiation involved.<br />
  14. 14. Cardiac Scantwo types of scanners<br />Multidetector Computed Tomography (MDCT)<br />Electron Beam Computed Tomography (EBCT)<br />
  15. 15. Medical ProcedureThrombolytic Therapy<br />Process where drugs are injected into a blood vessel to dissolve <br />blood clots or thrombosis.<br />
  16. 16. Thrombolytic therapy<br />Patients have a better chance of surviving heart attack or stroke when given thrombolytic drugs within 12 hours. <br />Also used for pulmonary embolism.<br />Deep vein thrombosis<br />
  17. 17. Thrombolytic Therapy<br />Patients suffering from the following are given this treatment.<br />Chest pain<br />Blurred vision in one eye<br />Slurred speech<br />Severe swelling in extremity<br />Pain or numbness in a limb<br />Sudden weakness<br />Numbness or tingling in one side of the body<br />
  18. 18. Thrombolytic therapyDrugs used<br />Lanoteplase<br />Recteplase<br />Staphylokinase<br />Streptokinase<br />Tenectplase<br />Urokinase<br />
  19. 19. Thrombolytic therapy<br />Patients will not receive this therapy if…<br />Recent head injury<br />Bleeding problems<br />Uncontrolled blood pressure<br />History of internal bleeding<br />Pregnancy<br />Surgery<br />Trauma <br />Taking blood thinning medications<br />Diabetes<br />
