Question 1

what path is associated with systolic regurgitation murmur, balloon appearance of heart on CXR?

Answer 1

dilated cardiomyopahty

Question 2

what is the path that is associated with hypertrophic cardiomyopathy, muscle weakness, loss of DTR, vibratory sense, and proprioception?

Answer 2

Question 3

define kussmaul sign

Answer 3

inc JVP on inspiration instead of a normal dec

Question 4

explain the mech of kussmaul sign

Answer 4

during inspiration –> negative intrathoracic pressure is not transmitted to the heart –> impaired filling of the Rt. ventricle –> blood backs up into vena cava and inc JVD during inspriation

Answer 19

low voltage ECG despite thick myocardium

Question 20

name 4 causes for restrictive/infiltrative cardiomyopathy

Answer 20

1. sarcoidosis
2. amyloidosis
3. postradiation fibrosis
4. endocardial fibroelastosis (thick fibroelastic tissue in endocardium of young children)

Question 21

what treatment of HF improves both symptoms and mortality?

Answer 21

hydralazine with nitrate

Question 22

what treatment of HF is used for symptomatic relief?

Answer 22

thiazide/loop diuretics

Question 23

the diff btw systolic vs diastolic dysfunction?

Answer 23

EF is reduced in sysotlic (normal is diastolic)

EDV is inc in systolic (normal in diastolic)

Answer 29

penicillin

Question 30

explain anitschkow cells

Answer 30

“activated histiocyte” enlarged macrophages with ovoid, wavy, rod-like nucleus

Question 31

what is the order of the most affected valve to the least affected valve in rheumatic fever?
