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