      • The condition in which cardiac output is insufficient in meeting the needs of the body and lungs is called [...].
      • heart failure
      • 100.0%
      • Cardiogenic shock is another name for [...].
      • acute heart failure

      • Does the term "heart failure" generally refers to acute or chronic heart failure?
      • Chronic
      • 100.0%
      • Left heart failure leading to right heart failure is known as [...].
      • congestive heart failure
      • 100.0%
      • Why does left heart failure lead to pulmonary congestion and pulmonary oedema?
      • Increased end-diastolic pressure causes increased filtration in the pulmonary circulation
      • 100.0%
      • In heart failure, why do compensatory mechanisms which keep cardiac output and blood pressure constant lead to increased myocardial damage?
      • Compensation occurs through increased heart rate, contractility, and afterload --> more cardiac work and more O2 demand
      • 100.0%
      • What is the most common cause of right heart failure?
      • Left heart failure
      • 100.0%
      • Why does left heart failure cause orthopnoea?
      • Pulmonary congestion is exarcebated by the supine position
      • 100.0%
      • What does decompensation refer to in heart failure?
      • Inability of the body to maintain cardiac output and blood pressure at rest
      • 85.7%
      • In diastolic heart failure, the ejection fraction is [...]%.
      • >50
      • 85.7%
      • Is left or right heart failure more common?
      • Left
      • 85.7%
      • Is systolic or diastolic heart failure more common?
      • Systolic
      • 85.7%
      • Why does heart failure lead to exercise intolerance?
      • Increased sympathetic tone in response to exercise can't push cardiac output enough to meet demand
      • 85.7%
      • Why does right heart failure lead to oedema in the extremities?
      • Increased venous pressure --> increased hydrostatic pressure
      • 85.7%
      • Why does right heart failure cause jugular venous distension?
      • Increased venous pressure
      • 85.7%

      • Myocardial infarct due to coronary artery disease
      • 85.7%
      • As heart failure becomes more severe, what happens to end-diastolic pressure and why?
      • Increases in order for stroke volume to stay constant
      • 71.4%
      • Why does chronic heart failure lead to dilation of the heart?
      • Increased end-diastolic volume
      • 71.4%
      • In systolic heart failure, the ejection fraction is [...]%.
      • <50
      • 57.1%
