Which is the higher pressure system: the pulmonary or systemic circulation?
Systemic circulation is higher pressure
Which is the lower pressure system: the pulmonary or systemic circulation?
Pulmonary circulation is lower pressure
Which side of the heart (right or left) propels blood through the pulmonary circulation?
Right
Which side of the heart (right or left) propels blood through the systemic circulation?
Left
There are six BASIC pathophysiologic mechanisms of cardiac dysfunction. What are they?
(1) Pump failure: Weak contractility and emptying of chambers, impaired filling of chambers.
(2) Obstruction to forward blood flow: Valvular stenosis, vascular narrowing, systemic or pulmonary hypertension.
(3) Regurgitant blood flow: Volume overload of chamber behind failing affected valve.
(4) Shunted blood flows from congenital defects: Septal defects in heart, shunts between blood vessels.
(5) Rupture of the heart or a major vessel: Cardiac tamponade, massive internal hemorrhage.
(6) Cardiac conduction disorders (arrhythmias): Failure of synchronized cardiac contraction.
There are six short- and long-term compensations that help maintain cardiac output for a while in the face of cardiac disease. What are they?
(1) Increased heart rate
(2) Increased peripheral resistance
(3) Increased blood volume
(4) Redistribution of blood flow
(5) Cardiac dilation
(6) Myocardial hypertrophy
Is dysfunction of the mitral valve more likely to cause left-sided heart failure or right-sided heart failure?
Left-sided heart failure
Is dysfunction of the aortic valve more likely to cause left-sided heart failure or right-sided heart failure?
Left-sided heart failure
Is dysfunction of the tricuspid valve more likely to cause left-sided heart failure or right-sided heart failure?
Right-sided heart failure
Is dysfunction of the pulmonic valve more likely to cause left-sided heart failure or right-sided heart failure?
Right-sided heart failure
The decreased blood flow to peripheral tissues caused by heart failure is called …
Forward failure
The accumulation or backing up of blood “upstream” from a failing heart chamber is called …
Backward failure
What does the term “forward failure” mean as it pertains to the systemic effects of heart failure?
The decreased blood flow to peripheral tissues caused by heart failure.
What does the term “backward failure” mean as it pertains to the systemic effects of heart failure?
The accumulation or backing up of blood “upstream” from a failing heart chamber
