80
what causes diastolic heart failure
LV is stiff and can't easily relax causing thickening of the LV
81
how are hormones related to HF
overactive RAAS and sympathetic NS to prevent heart from failing causes diminished natriuretic peptides leading to an imbalance of hormones furthering the decline in heart function
82

104
4 parameters for LVAD
speed, flow, pulsatility index, power
105

native heart's ability to pump blood and contribute to CO, higher= heart is pulsing on its own, lower= heart isn't pulsing as much on its own
106
3 LVAD hemodynamics
native LV contributon, volume status, IV meds
107
after pt is on LVAD do they get to stop taking meds?
no, they must continue taking meds to keep their immune system and body functioning properly
108
orthotopic heart transplant (OHT) requirements
<70 yo, end stage heart disease, signficiant risk mortality, no active infection, no cancer, no organ impairment, BMI <35, abstain from alcohol and tobacco, medical and financial support
109
methylprednusolone
glucocorticoid, anti-inflammatory by reversing capillary permeability, used in IV after surgery, SE: acne, adrenal suppression, fluid retention (all hormone related)
110
prednisone
PO, anti-inflammatory, SE: anaphylaxis, bradycardia, moon face
111
what happens with OHT hemodynamics
no parasympathetic or sympathetic input so pts will have an increase in resting HR and rely on catecholamines to increase HR during activity
112
rejection of transplant symptoms and why are they important
usually similar to HF symptoms so pts may not be as quick to report them to us: fatigue, edema, irregular heartbeat, decreased activity tolerance
113
goals of HF meds
either increase contractility to decrease HR OR decrease afterload to reach euvolemia (neutral volume)
114
group of guideline directed medical therapy drugs
ACEI/ARB, beta blocker, aldosterone antagonists, nitrates
115
how does ACEI treat HF
decrease afterload, decrease preload, increase CO by dilating vessels
116
how does beta blocker treat HF
only used for stable HF b/c blocks SNS system to decrease ionotropy and increase preload
117
how does aldosterone antagonist treat HF
very common K+ sparing drug which prevent arrythmias. PT related: risk for hypotension, dehydration, hyperkalemia
118
how do nitrates treat HF
dilate vessels to decrease afterload and increase SV b/c allows heart to function better
119
NY classes of HF class 3 compared to class 4
3= symptoms only during activity and not at rest
4= symptoms at rest and during activity
120
what are loop diuretics good for HF tx
decrease edema (symptom relief), causes vessel walls to become less dilated since there's less fluid there, also increases risk for dehydration
121
why would vasopressors be used to treat HF
they do vasoconstriction so are good for tx of cardiac arrest, septic shock, hypotension
122
alpha receptor
beta 1 receptor
beta 2 receptor
significant vasoconstrictor
heart: some vasoconstriction
lungs: vasodilation
123
doses of epinephrine differences in reaction
beta= lower dose = dilates= decrease BP
alpha= higher dose= constrict= increase BP
124
norepinephrine
most commonly used vasopressor= increase systemic vascular resistance, increase BP
125
why is vasopressin given exogenously
with septic shock vasopressin stores are depleted by 96 hours
126
dopamine doses
low= vasodilation
medium= increase HR and ionotrophy
high= vasoconstriction
127

assist with contractility
128
