Q

what worsens subaortic outflow obstruction (2)

A
  • increased contractility (exercise, digoxin)
  • decreased LV volume (dehydration, maneuvers)
23
Q

most are asymptomatic but the ones w/ sx are dyspnea on exertion, palpiations, chest pain, exertional syncope

24
Q

2 tx of HCM

A
  • reduce outflow gradient w/ BB, non-DHP CCBs, disopyramide
  • ICD placement for secondary prevention of sudden death in hx of Vfib or sustained VT, syncope or holter monitor events
25
4 things ppl w/ HCM should avoid
* dehydration * exertion & strenous exercise * digoxin * vasodilators, diuretics, ACE/ARB, nitrates
26
inflammation of the pericardium
pericarditis
27
dresslers syndrome
post MI pericarditis + fever
28
5 (technically 4) Ps of pericarditis
* Pleuritic pain (sharp pain worse w/ inspiration) * Postural (worse supine) * Persistent chest Pain * Pericardial friction rub
29
* diffuse ST elevations (concave up) + PR depressions in precordial leads * ST depression & PR elevation in avR
pericarditis ECG findings
30
normal echo but still done to r/o effusion and look for associated myocarditis
ECHO findings in pericarditis
31
1st, 2nd, 3rd line tx of pericarditis
1. NSAIDs or aspirin 2. colchicine 3. steroids if refractory (sx >48hrs)
32
loss of ventricular elasticity (fibrosis, calcification) leading to restriction of diastolic filling; caused by acute pericarditis and chronic inflammation
constrictive pericarditis
33
# these are symptoms of? * dyspnea is main sx * R sided heart failure sx * Pericardial knock
constrictive pericarditis
34
what is high pitched 3rd heart sound from sudden cessation of ventricular filling & what condition is it associated with
pericardial knock associated with constrictive pericarditis
35
which two **pericardial diseases** have both pulsus paradoxus and kussmauls sign
* pericardial tamponade * constrictive pericarditis
36
which pericardial dz would show diastolic collapse of cardiac chambers, hemodynamic compromise on an echo?
pericardial tamponade
37
which pericardial dz would show pericardial thickening and calcification on an echo?
constrictive pericarditis
38
which surgical procedure is done to definitively treat constrictive pericarditis?
pericardiectomy
39
which procedure is done to treat pericardial tamponade?
pericardiocentesis
40
# name the condition increased fluid in the pericardial space
pericardial effusion
41
t/f, pericardial effusion shares the same etiologies as acute pericarditis
true
42
sx of pericarditis + **distant/muffled heart sounds** is associated with which two pericardial dz?
pericardial effusion pericardial tamponade
43
# these diagnostic test results is associated with which condition * ECG: **low QRS complex, electrical alternans** * Echo: increased pericardial fluid with NO hemodynamic compromise
pericardial effusion
44
# name the condition pericardial effusion causing pressure on heart which limits ventricular diastolic filling
pericardial tamponade
45
sx include: becks triad, pulsus paradoxus, kussmauls sign
pericardial tamponade
46
# name the phenomenon pulses disappear or SBP drops more than 10 w/ inspiration
pulsus paradoxus
47
what is becks traid (list the 3 things)
* distant heart sounds * increased JVP * systemic HYPOtension
48
definitive management for recurrent pericardial tamponade is ___
pericardial window
49
# name the condition **systolic** dysfunction causing ventricular dilation; decreased LVEF < 40%
dilated cardiomyopathy * mostly in 20-60 yo males
50
can be caused by infectious, infiltrative dz, pregnancy, alcohol abuse, etc but the most common cause is idiopathic; makes up majority of all cardiomyopathies
dilated cardiomyopathy
51
# which cardiomyopathy has these clinical findings * S3 gallop * lateral PMI displacement * other heart failure signs
dilated cardiomyopathy
52
# which cardiomyopathy fits this finding * Echo: **LV dilation, reduced EF**, LV hypokineses * CXR shows cardiomegaly, pulmonary edema
dilated cardiomyopathy
53
T or F: you treat dilated cardiomyopathy the same way you treat HFrEF
true
