Myocarditis/Heart Failure Questions
15. Alex suffers from myocarditis (inflammation of heart muscle cells) which results in cardiac muscle cell damage (contractile cells). How would you expect contractility (force of contraction) to change? A. No change B. Increase Decrease 16. Based on your answer to #15, which of the following direct results will occur in a single diac cycle? A. Increased end systolic volume B. Decreased end diastolic volume Decreased stroke volume DA and C E. A, B and C 17. Based on your answer from question #16 what will happen to Alex's cardiovascular function over time? A. Reduced mean arterial pressure B. Decreased heart rate C. Increased blood flow D. A and C E. A, B and C 18. Based on your answer from question #17, which of the following fast acting compensation mechanisms will occur? A. An increase in arteriolar resistance B. A decrease in norepinephrine (NE) release C. Increased water retention mediated by the renal system D. A decrease in heart rateExplanation / Answer
19. Correct option is A. Mean arterial pressure is considered to be the average pressure in a patient’s arteries observed in one cardiac cycle. It is one of the indicators to find perfusion of oxygen to vital organs.Higher the MAP, it will help in increasing oxygen supply to all tissues and organs.
20. Correct option is B. Due to stiffening of ventricular muscles, it will result in inadequate ventricular relaxation. End-diastolic volume is the volume of blood which remains in right and/or left ventricle at the end before systole. Due to stiffening of muscles, the relaxation of muscles will be incomplete and the end diastolic volume will reduce.
