Question 1

Question
CVP = ??
Answer
  • Central Venous Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)
  • Cardiac Venous Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)
  • Central Ventricular Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)
  • Cardiac Ventricular Pressure (measured from the height of the jugular vein to “see how high the column of blood is in the jugular vein and above that it’s collapsed”)

Question 2

Question
"Starling curves" (Ventricular function curves). Which is which?
Answer
  • Normal
  • Sympathetically stimulated (eg exercise)
  • Following heart attack

Question 3

Question
If Cardiac Output (CO) falls 50%, BP will also fall 50% (because BP = CO * TPR). >> Reduced baroreceptor firing >> increased sympathetic activity. This results in which of the following: (after a while, this is useless, but of benefit immediately)
Answer
  • Increased HR
  • Decreased HR
  • Increased contractility
  • Decreased contractility
  • Selective arteriolar vasoconstriction
  • Selective arteriolar vasodilation
  • Venoconstriction
  • Venodilation

Question 4

Question
ANF is a peptide hormone stored in atrial cells of the heart. It inhibits Na+ reabsorption in Kidney and promotes Na+ and H2O loss. This is a way that the RAAS thing works. ANF = ??
Answer
  • Atrial Naturetic Factor
  • Arterial Naturetic Factor
  • Atrial Natiuric Factor
  • Arterial Natiuric Factor

Question 5

Question
Which of the following are pathways by which the heart responds to reduced CO?
Answer
  • Baroreceptor/sympathetic response
  • RAAS response
  • Hypertrophy of the heart

Question 6

Question
Systolic vs Diastolic heart failure. Which one has reduced ejection fraction?
Answer
  • Systolic
  • Diastolic

Question 7

Question
What’s HFpEF?
Answer
  • Heart Failure, preserved Ejection Fraction (Diastolic Failure)
  • Heart Failure, preserved Ejection Fraction (Systolic Failure)

Question 8

Question
Systolic vs Diastolic heart failure. Which [generally] has worse patient outcomes?
Answer
  • Diastolic
  • Systolic

Question 9

Question
Systolic vs Diastolic heart failure. Which is particularly common in diabetic and obese patients?
Answer
  • Diastolic
  • Systolic
