heart failure treatment Flashcards
K+ problems associated with
drugs
Mg+ problems associated with
PVCs
neurohormonal model
- prolonged SNS stimulation- angiotensin II vasoconstriction(kidneys need more volume)- aldosterone
med that does not affect neurohormonal pathway
loop diuretics / diuretics = used to treat symptoms and must be used in conjunction with ACE-I and BB
most common symptom of HFrEF
SOB (spectrum - exertional to at rest)
most frequently overlooked symptom of HFrEF
chronic non-productive cough, worse in recumbent
pulse pressure
difference between SBP and DBP
this condition never appears with S4
atrial fibrillation
beta blocker positive benefits
decrease circulating catecholamines to reduce SNS response reduce overstimulation of RAAS
most common reason for development of HFpEF
chronic hypertension
cardiogenic shock + lasix need to know
80 mg IV yields lt 2L uop/4 hoursstart 40mg/hr - goal: 100cc uop/hr goa
cardiogenic shock: dopamine appropriate if
↓BP + ↓SVR
milrinone is…
inodilator PDE
dobutamine is…
beta-agonistinodilator (some chrono)improves CO with some systemic vasodilation
med that directly interferes with neurohormonal model
ACE-I
