Questions and Answers

Which of the following best describes the pathogenesis of Ischemic Heart Disease?

  • Due to reduced blood flow to the heart from thrombosis and atherosclerotic occlusion
  • Resulting from atherosclerosis leading to inadequate coronary perfusion and subsequent myocardial infarction (correct)
  • Caused by vasospasm of coronary arteries resulting in acute infarction and cardiac myocyte death
  • Arising from asymptomatic atherosclerosis and stable angina due to coronary artery occlusion

    • What is the usual clinical presentation when coronary angiography shows narrowing of the lumen less than 70%?

  • It causes angina symptoms
  • It results in unstable angina (pre-infarction)
  • It is usually asymptomatic (correct)
  • It leads to acute infarction and death of cardiac myocytes

    • What occurs when there is total acute coronary blockage?

  • Collateral flow develops rapidly, preventing acute infarction and cardiac myocyte death
  • There is no time for collateral flow to develop, resulting in acute infarction and death of cardiac myocytes (correct)
  • The heart adapts to the blockage, preventing cardiac myocyte death
  • The blockage leads to stable angina symptoms
