Cards Flashcards
Murmurs I / II
I- faint, not heard in all positions
II- soft, heard in all positions
Murmurs III / IV
III - loud, no thrill
IV - palpable thrill
Murmurs V / VI
V - heard with stethoscope partially off chest
VI - heart w/ stethoscope completely off chest
Bevacizumab AE
VEGF inhibitor
causes HTN
Antibiotics for SBE prophylaxis
amox 1 hour prior to procedure
ASDs - different types
secundum ASDs
primum ASDs
sinuous venous
ASDs- when do you typically close
ages 3-4
VSD- types
perimembranous most common
arterial, muscular, inlet
Size of VSDs
related to AV area
small is 1/3, moderate 1/3 to 2/3, large is >2/3
AVSD - associated features/symptoms
primum ASD
inlet type of VSD
MVP associated with..
hyperthyroidism
Transposition of Great Arteries - Presentation
Usually no murmur
cyanosis in first 12h after birth, can be prolonged by VSD
Transposition of Great Arteries - Where does blood mix
ASD or PFO
VSD
Premature CAD
less than 55 in males
less than 65 in females
Truncus Arteriosus- primary issue
truncus doesn’t divide into aorta and main pulm a
Truncus Arteriosus- murmur
systolic murmur at LSB (VSD)
Partial APVD
at least one pulmonary vein returns to LA
Total APVD
no pulmonary veins return to LA
Systolic HF- Treatment
ACEI or ARB
loop diuretic
BB
ARB+neprilysin inhibitor (valsartan-sacubitril)
Replace ACEI or ARB with ARNI in patients with chronic symptomatic HFrEF who tolerate ACEI and ARB therapy
HF and aldosterone antagonists
a. Reduce mortality and HF hospitalizations in patients with symptomatic HF (NYHA II-IV) and HF after acute MI
Isosorbide Dinitrate-Hydralazine
Use in those intolerant to ACEI or ARB (like CKD)
Use in combination with therapy in African Americans
CCB and Heart Failure
Nondihydropyridine CCB, verapamil and dilt have detrimental effects in patients with SHF due to negative inotropic effects
Diastolic HF Therapy
SBP less than 130
?Maybe spirolactolone
Turner Syndrome associated cardiac etiology
bicuspid aortic valve
Hepatic Vein
deoxygenated blood from liver to IVC
Portal Vein
blood from GI tract to liver (has nutrients and toxins)
Systole
heart contracts
blood from ventricles to aorta and pulmonary artery
Diastole
heart relaxes
blood from atria to ventricles
S1
closure of mitral and tricuspid valves
S2
closure of aortic and pulmonary valves
aortic closes before pulmonary normally
S3
early diastole
rapid filling of ventricles (dilated or decreased compliance)
VSD, CHF
S4
late diastole
decreased ventricle compliance
Hypertrophic Cardiomyopathy- genetics
AD
myosin, troponin
Cardiac Syndrome X
angina and stress test abnormalities in absence of coronary artery abnormalities
Abdominal Aortic Aneurysm Repair
> 5.5 cm or growth of more than 0.5cm/year
Right Bundle Branch Block
rSR’ in V1
qRs in V6 (slurred R wave)
Restrictive Cardiomyopathy
diastolic dysfunction
Therapy after MI
Aspirin, ACEI, BB, Statin, P2Y12 Inhibitor
Beta blockers MOA
reduce myocardial oxygen demand
Right Ventricular Infarction
ST elevated in right sided leads
hypotension, elevated JVP
avoid nitrates
Cardiogenic Shock
high preload
LOW CO
high SVR
high PCWP
alpha one
vasoconstrict
beta one
myocardium
inotropy, chronotropy
beta two
blood vessels
vasodilation
dobutamine
B1 and B2
increase inotropy, chronotropy
vasodilation and afterload reduce
dopamine
d1 –> b1 –> a1
norepinephrine
a1 > b1
phenylepinephrine
a1
epinephrine
b1 –> a1
milirinone
PD3 inhibitor
inotropy, profound systemic and pulmonary vasodilation
use if PAH/RHF
E/e’ ratio
greater than or equal to 15 in DHF
Hydralazine + CAD/Angina
increases arterial vasoconstriction –> worsening chest pain
use in combination with nitrate
ST changes
has to be in 2 continguous leads
greater than 1mm for limb leads
greater than 2mm for chest leads
Anterior MI- leads and vessel
V3,V4
LAD
Lateral MI- leads and vessel
I, avL, V5-V6
left circumflex
Septal MI- leads and vessel
VI, V2
LAD
Inferior MI- leads and vessel
II, III, avf
RCA > LCX
cardiac tamponade
hypotension
pulsus paradoxus
elevated JVP
MVO2
myocardial volume oxygen consumption
Austin Flint Murmur
aortic regurg
diastolic rumble at apex
regurgitant aortic jet directed toward anterior leaflet of mitral valve causing premature closure
Aortic Sclerosis Murmur
early systolic murmur @ RSB
What should be done before cardioversion
- anticoagulation
- TEE to exclude intracardiac thrombus
Inferoposterior MI
ST depression V1-V3
tall R in V2 and V3
Murmur that increases with Valsalva (decreased preload)
HCM
Murmur that decreases with Valsalva (decreased preload)
aortic or pulmonary stenosis
