What is a major sign of Ventricular dysfunction-
exertion dyspnea
HF can develop after these conditions
a. long-standing hypertension, coronary artery disease (CAD), and myocardial infarction
What are the symptoms of the pump of the heart not being effective
edema, orthopnea, exertional dyspnea
orthopnea
shortness of breath while lying flas
HF symptoms when not perfusing
i. restlessness, confusion, and decreased attention span LOC
ii. Cyanosis(saturation) and ↓CR(perfusion) from a lack of oxygen
iii. Fatigue or weakness
iv. Rapid or irregular heart beat
HF pulmonary congestion causes what symptoms
1. cough
2. wt gain
3. DJV
4. increased urination
5. anorexia, indegestion
what position is recommended for pt w/ HF

DON'T PUT BED BELOW

why
90 degrees
NOT BELOW 30 DEGREES
fluid would rush back into lungs
talk about diabetes and HF
all diabetics are at risk of HF regardless if they have HTN or MI

* constant inflammatory response causes hypertrophy
risk factors for HF
>65
HTN
smoking
diabetes
obesity
high serum cholesterol
1. normal ejection fraction
2. HF ejection fraction
3. EF % that is life threatening arrhythmia
1. normal: 60-80%
2. HF: <40%
3. life threatening arrhythmia: <35%
G. Systolic HF causes:
a. Impaired contractile function (e.g., MI)
b. Increased afterload (e.g., hypertension)
c. Cardiomyopathy (increased preload, contraction)
d. Mechanical abnormalities (e.g., valve disease)
what is diastolic HF
inability of the heart to relax and refill
what is the ejection fraction in diastolic HF
normal
what's going on w/ lungs and heart in diastolic HF
pulmonary congestion
pulmonary HTN
ventricular hypertrophy
b. Diastolic failure is characterized by
high filling pressures due to stiff or noncompliant ventricles and results in venous engorgement in both pulmonary and systemic vascular systems.
a. NYHA: I-IV- classified according
B. ACC/AHA Stage- classified according
a. NYHA: I-IV- classified according to pt funtioning
b. ACC/AHA Stage- classified according to stage of disease
which stage has conditions or behaviors associated w/ HF (atherosclerosis, CAD, diabetes, family hx cardiomyopathy, hx alcohol, rheumatic fever, cardiotoxic meds
Stage A: ACC/AHA
Which stage has structural chg but no s/s
Stage B: ACC/AHA
class 1 of NYHA
Which stage has structural chg and sysmptoms
stage C AHA/ACC
class II or III NYHA
what is a huge clinical sign of HF
s3
gallop
when the heart is struggling, what are the compensatory mechanisms
SNS stimulation
Activation of RAAS system
myocardial hypertrophy
activation of peptides and hormones
What effects does an increase of SNS have on cardio
increases HR
increases conductivity
peripheral constriction
Pulsus alternans- what is this? When is it seen
alternates in strength- bound and then goes regular

SNS stimulation in HF
What are you going to see w/ pt w/ HF and SNS stimulation
2. Tachycardia-how do you know it’s tachy?
3. Pulsus alternans- alternates in strength- bound and then goes regular how do you know?
4. PAC premature atrial contractions or AF atrial fibrillation
5. S3 gallop first sign of HF
activation of RAAS causes
Na/H2o retention
cardiac remodeling- hypertrophy, fibrosis
monitoring and assessment of HF includes:
1. lung ausculations wheeze, crackles that don't go away w/coughing- inspiration and expiration, r/t engourged blood vessels
2. neck veins, abd girth, hepatomegalay,
3. I&O, daily wt
labs to check w/ HF
1. BNP/serum creatinine, creatine clearance
2. urine analysis for proteinuria microalbuminuia early indicator of decreased compliance of the heart
3. electrolytes
When are these activated? TNF, IL-1 and IL-6, BNP, ADH, Endothelin
Compensatory mechanisms w/ heart failure
1. What is endothelin
2. what stimulates its release
3. what does it cause in the body
ii. Endothelin a potent vasoconstrictor is stimulated by ADH, catecholamines, and angiotensin II, causing:
1. Arterial vasoconstriction
2. Increase in cardiac contractility
3. Hypertrophy
What are antagonist to Endothelin and Aldosterone
ANP and BNP
What is Paroxysmal nocturnal dyspnea:
after falling asleep edema rushes to lungs pt wakes with breathlessness.
what s/s will a patient w/ HF display
a. Dyspnea:
b. Excertional dyspnea:
c. Orthopnea:
d. Paroxysmal nocturnal dyspnea:
e. Ventricular dysrhythmias- the collateral circulation does not keep with the growth of cardiac tissue.
what type of V/Q mismatch occurs with heart failure

Why is this more dangerous than respiratory V/Q mismatch
dead space, problem w/perfusion

heart cannot give any more output
M. Clinical manifestations of left sided heart failure:
a. Orthopnea-POSITIONAL DIFF BREATHING
b. Dyspnea, tachypnea
c. Paroxsymal nocturnal dyspnea-
d. Cyanosis
e. Cool extremities/weak pulses-
f. Cough with frothy, blood-tinged sputum-
g. Breath sounds: Crackles, wheezes
h. Tachycardia
i. Hypotension or hypertension
