Cardiology Flashcards
systolic murmur that is heard in apex, radiates to axilla and increases with grip maneuver and decreases with valsalva
mitral regurgitation
sounds heard with acute mitral regurg
soft decrescendo systolic murmur
decreased S1
presence of S4
four MCC of acute heart failure
papillary muscle rupture
infective endocarditis
rupture of chordae tendinae
chest wall trauma with compromise of valvular apparatus
CF in Ehlers Danlos
pes planus scoliosis thin, velvety, fragile skin (cigarette paper) easy bruisability past hx of hernias and MVP
cocaine related chest pain - tx.
tx early with BDZs
-avoid beta blockers (to avoid causing coronary vasospasm)
Tx. persistent HTN after cocaine use
phentolamine
- also decreases coronary vasospasm
alt. nitroglycerin, nitroprusside
valve dz in an immigrant or a pregnant person
mitral stenosis
valve dz in Turner’s syndrome pt with coarctation of the aorta
bicuspid aortic valve
valve dz in pt presenting with palpitations, atypical chest pain not with exertion
MVP
systolic murmurs
AS
MVP
MR
HOCM
diastolic murmurs
AR
MS
all right sided murmurs increase in intensity with…
inhalation
all left sided murmurs increase in intensity with…
exhalation
effect of squatting and lifting legs in the air on heart
return blood to heart therefore, increase venous return to the heart
effect of Valsalve maneuver and standing up on the heart….
decrease venous return to the heart
which murmurs get louder with squatting and leg raise
all right sided murmurs
AS, AR, MS, MR
which murmurs get softer with squatting and leg raise
MVP
HOCM
- these murmurs INCREASE with valsalva
which murmurs increase in loudness with valsalva/standing
HOCM
MVP
Effect of handgrip on heart and which murmurs does it make louder?
- increases afterload
- Worsens VSD, AR and MR murmur
- Improves/softens MVP and HOCM
effect of amyl nitrate on heart and murmurs
- decreases afterload
- softens, AR and MR
- worsens MVP and HOCM (increases the obstruction and degree of prolapse)
effect of amylnitrate and handgrip on murmur of AS
handgrip actually makes AS murmur softer –> creates less of a gradient between LV and aorta. Amyl nitrate increases the gradient and thus, increases murmur of AS
any murmur that improves with amyl nitrate will improve with tx with what med?
ACEI
murmurs: AR, MR, VSD
best initial test for valve lesions (1)
most accurate test for valve lesions (2)
- echo (TTE –> TEE)
- left heart catheterization
- also order EKG and CXR on ccs
best treatment for regurgitant lesions
vasodilator therapy - ACEI or ARBs, nifedipine
in which murmurs is diuretic therapy indicated
if murmur improves with valsalva (decreased venous return) –> AS, AR, MS, MR, VSD
crescendo-descrescendo systolic murmur, heard best at 2nd intercostal space, radiates to carotid arteries, delayed carotid upstroke
AS
how do you assess severity of AS?
measure pressure gradient across valve
Normal < 30
Moderate 30-70
Severe > 70 mmHg
best initial therapy for AS (1)
treatment of choice for AS (2)
- diuretics
2. valve replacement
diastolic descrescendo murmur heard best at left sternal border
AR
clinical findings unique to AR
Quinke’s pulse - pulsations in fingernails
Corrigan’s pulse - bounding pulses
Musset’s sign: head bobbing up and down with each pulse
Duroziez’s sign - murmur heard over femoral artery
Hill sign - BP gradient high in lower extremities
Tx. aortic regurg
- ACE, ARBs and nifedipine - best initial
- add furosemide
- surgery if EF < 55%
diastolic rumble murmur with opening snap, best heard at cardiac apex, S1 louder than S2
mitral stenosis
unique clinical findings in MS
dysphagia and hoarseness due to pressure of LA pressing on esophagus and recurrent laryngeal nerve (Ortner’s syndrome)
atrial fibrillation
mitral facies - pinkish-purple patches on cheeks
XR findings in MS
LA enlargement with flattened left heart border
dilated pulm vessels
EKG findings in MS
broad, notched P waves
RVH: tall R in V1 and V2
Tx. mitral stenosis
diuretics
most effective = balloon valvuloplasty
if pregnant - do not hesitate to perform valvuloplasty
holosystolic murmus that obscures both S1 and S2, heard best at apex that radiates to axilla, S3 gallop often present
mitral regurg
S3 gallop
assoc. with fluid overload states, such as CHF or MR
Tx. mitral regurg
- ACE, ARBs and nifedipine - best initial
- add furosemide
- surgery if if LVEF < 60% or LVED > 40 mm
holosystolic murmur at the LLSB that worsens with exhalation, squatting and leg raise
VSD
murmur assoc with ASD
fixed splitting of S2
Tx. ASD
percutaneous or catheter devices
- repair indicated when the shunt ratio exceeds 1.5:1
causes of wide splitting of S2 with delayed P2
RBBB
PS
RVH
pulm HTN
causes of paradoxical splitting of S2 with A2 delayed
LBBB
AS
LVH
HTN
best initial test for cardiomyopathy
ECHO
most accurate method for determining EF
MUGA
nuclear ventriculography
Tx. dilated cardiomyopathy
ACEi/ARBs
BB
spironolactone
S4 gallop
sign of LVH and decreased compliance or stiffness of the ventricle
Tx. HCM
beta blockers
diuretics
Dx. findings in restrictive evaluation
cardiac cath –> rapid x and y descent
EKG –> low voltage
echo = mainstay of diagnosis
single most accurate dx test: endomyocardial biopsy
best initial test for pericarditis
EKG –> diffuse ST elevation, PR depression
best initial therapy for pericarditis
NSAID
if the pain persists for > 2 days, add prenisone orally
CF in pericardial tamponade
SOB hypotension JVD pulsus paradoxus EKG: electrical alternans
most accurate diagnostic test for tamponade
echo –> diastolic collapse of RA and RV
results of right heart cath in tamponade
equalization of all pressures in the heart during diastole

unique features of constrictive pericarditis
sx of chronic RHF -> JVD, hepatomeg, ascites, edema
Kussmaul’s sign: JVD with inspiration
pericardial knock
best initial therapy for constrictive pericarditis
diuretics
most effective therapy for constrictive pericarditis
pericardial stripping
pt presents with severe chest pain that radiates to the back. on exam,he is hypertensive with BP are greater in the right arm vs left arm - dx? best initial test? most accurate test?
Dx. thoracic dissection
initial test: CXR shows widening mediastinum
best test: CT angio = TEE = MRA
first steps in management if you suspect pt with thoracic dissection
1) start BB get EKG, CXR --> CT angio or TEE or MRA 2) nitroprusside to control BP 3) place in ICU 4) get surgery consult
best initial test for PAD
ankle brachial index
normal should be > 0.9
best initial therapy for PAD
- aspirin or clopidogrel (most effective)
- ACEI
- supervised exercise program
- cilastazol - only if severe symptoms
- lipid control with statins
pentoxyfylline
marginally effective therapy for PAD, used only if cilostazol is ineffective
for CCS, tests to order once A-fib is found
- ECHO
- TFTs
- electrolytes: K+, Mg, Ca
- troponin or CK MB
Tx. unstable pt with A-fib
synchronized cardioversion
- without any TEE or anticoagulation
Tx. stable pt with A-fib
- slow HR with BB (metoprolol or esmolol) or CCB (diltiazem)
- anticoagulation with warfarin (INR 2-3) or dabigatran
CHADS
CHF HTN Age > 75 Diabetes Stroke/TIA (2) - score > 2 warrants warfarin if score < 2, can tx with aspirin
causes of multifocal atrial tachycardia
secondary to hypoxia (COPD), hypokalemia, hypomag, coronary/valvular dz, meds (theophylline, aminophylline, isoproterenol)
