Barron’s Cardio Flashcards
symptoms of hypertrophic cardiomyopathy
same as DIASTOLIC HF
(can eject, cant fill)
thickening of heart muscle and septum at expense of LV. “Fat Septum”
fatigue, dyspnea, CP, S3, S4
arrhythmias SUDDEN CARDIAC DEATH
treatment of hypertrophic cardiomyopathy
(same as diastolic HF)
what to avoid
SAME AS FOR DIASTOLIC HF BB ACE/ARB diuretics (low dose) aldosterone agonists CCB
AVOID: negative inotropes, dehydration, tachyarrhythmias
symptoms of dilated cardiomyopathy
same as systolic HF
Enlarged atria and/or ventricles
MV regurg common
treatment of dilated cardiomyopathy
(similar to SYSTOLIC HF)
What to avoid
similar to systolic HF
may progress through stages, classes
may require VAD, heart transplant
Systolic HF is characterized by:
EF < or =40% problem with ejection (filling ok) might be normal size heart or dilated PMI shift L (if dilated/large heart) Pulm edema (r/t poor emptying S3 decreased or normal BP increased BNP (nl <100) MV insufficiency
diastolic HF is characterized by:
EF >50%
problem with filling (ejection ok)
Systolic =
dilated =
Diastolic =
Hypertrophic=
which type of HF is characterized by MV insufficiency
Systolic aka dilated
to INCREASE PRELOAD
VOLUME EXPANDERS (crystalloids, colloids) PRESSORS
crystalloids (NS, LR, dextrose)
colloids (albumin)
to DECREASE PRELOAD
DIURETICS
DILATORS
MORPHINE
MORPHINE does what to preload
DECREASES
to INCREASE AFTERLOAD
PRESSORS ( Dogs Love Elevated Preload)
Dopamine, Levo, Epi, Phenylephrine
to DECREASE Afterload
DILATORS
ACE-I
CCB
IABP
What does IABP do?
How does it do it?
DECREASES AFTERLOAD
inflates during Diastole, deflates during systole (creating dead space.
increases perfusion to coronary arteries during inflation/DIASTOLE.
