[Exam 2] Chapter 29: Management of Patients with Complications from Heart Disease Flashcards
What is HF?
Inability of the heart to pump sufficient blood to meet the needs of the tissues for oxygen and nutrients.
HF: This syndrome is characterized by what?
Fluid overload or inadequate tissue perfusion
HF: This term indicates myocardial disease, which measn what
there is a problem with the contraction of the heart (systolic failure) or filing of the heart (diastolic failure)
HF: Can this be reversed?
Yes
HF: How does this usually progress?
Is usually a progressive, lifelong disorder managed with lifestyle changes and medications
HF: What does it mean if the heart cannot squeeze properly?
Systolic failure
HF: What does it mean if the heart cannot fill properly?
Diastolic failure
HF Patho: What are some examples of Myocardial Dysfunction?
Ischemic Heart Disease Hyperthyroidism MI Valve Disease Alcohol/Cocaine Abuse Hypertension
HF Patho: Myocardial dysfunction (HF) can lead to what changes in body?
Decreased CO
Decreased systemic blood pressure
decreased perfusion to kidneys
HF Patho: When there is a decrease blood pressure or cardiac output, what is activated?
Baroreceptors (Aortic Arch and Carotid Sinus)
HF Patho: After activation of the baroreceptors, what system is activated next?
The sympathetic nervous system which increases catecholamines (Epinephrine and norepinephrine)
HF Patho: The release of Catecholamines (Epinephrine and Norepinephrine) causes what?
Vasoconstriction, which increased afterload, blood pressure, and heart rate.
HF Patho: Decreased Cardiac Output or Blood Pressure of perfusion to kidneys activated what?
RAAS sysem
HF Patho: How does RAAS system work?
Angiotensin released from liver, and forms Angiotensin 1.
Renin combines with lungs to form Angiotensin II
HF Patho: Increase release of aldosterone causes what changes?
Sodium/Water retention
Arginine Vasopressin
Cytokines
Endothelin
HF Patho: What disease can cause the heart to not pump properly?
CAD
HF Patho: Why is the RAAS being activated a viscious cycle?
When activated, the patients retain fluid because kidneys think we are not getting enough perfusion. Need to hold onto more fluid which is the opposite of what we want in this situation
HF Patho: Why is activation of baroreceptors a problem?
We do not want vasoconstriction because the heart is already struggling with pumping blood to rest of body. Increases afterload heart must overcome.
HF Patho: What may happen to heart if this is prolonged?
Ventricular remodeling, where there is hypertrophy and dilation of ventricles and turn into large cells and impaired contractility.
HF Patho: In simple terms, why is HF a viscous cycle?
Because bodies mechanisms cause us to retain fluid which is what we don’t want a long with vasoconstriction. Heart works harder.
HF CMs: What are some signs of right sided heart fialure?
Viscera and Peripheal Congestion
Jugular Venous Distention (JVD)
Dependent Edema
Hepatomegaly
Ascites
Weight Gain
HF CMs:What are some signs of left sided heart failure?
Pulmonary Congestion, Crackles
S3 or Ventricular Gallop
Dyspnea on Exertion (DOE)
Orthopnea
Dry, Nonproductive Cough
Oliguria (Small Urine)
HF CMs: How should we view right-sided heart failure?
Rest of body. Manifestated by backing up of blood into body.
HF Right-Sided CMs: Why is Hepatomegaly seen with Right sided HF
Because the fluid is pushing back on the liver
HF Left-Sided CMs: What should we think for these CMs?
Lungs
HF Left-Sided CMs: Why will they have dyspnea?
Because of the congestion in the lungs
HF Left-Sided CMs: Why will they have orthopnea?
Because of the fluid in the lungs, and have to sit up to breathe
HF Left-Sided CMs: RIght-Sided HF goes where?
Back into the body
HF Right-Sided CMs: How will this patient appear?
Will have distended jugular veins, dependent edema in lower body, and wil have ascites
HF Left-Sided CMs: How will this person appear?
Will be skinner. Will have cyanosis on lips, feet, and fingertips. Aren’t getting enough oxygen.
HF Right-Sided CMs: Are they fatigued?
Yes, because they are now holding onto all that extra fluid
HF Left-Sided CMs: Auscultation will reveal what?
Fluids in the lungs.
HF Left-Sided CMs: How will their cough progress?
Will be dry originally, and then the person will cough of blood-tinged sputum.
HF Left-Sided CMs: Respirations increased why
because they can’t breathe properly because of lung buildup.
HF Left-Sided CMs: What will happen to Pulmonary Capillary Wedge Pressures?
Will be elevated because of HF. This pressure tells us what the left ventricle is doing.
HF Left-Sided CMs: They will have Paroxysmal Noctural Dyspnea, which is what
Condition that triggers sudden SOB during sleep
HF Medical Mx - Medication: How do Angiotensin-Converting Enzyme Inhibitors and Angiotensin II REceptor BLockers work?
Will decrease blood pressure and decrease afterload.
Includes Lisinopril
HF Medical Mx - Medication: How do Beta Blockers work?
They decrease BP and take stress off of heart and help so heart doesn’t work as hard.
HF Medical Mx - Medication: What do these medications end in?
Lol , like metoprolol, carvedilol (common for patients with HF)
HF Medical Mx - Medication: How do diuretics work?
Going to get fluid off so fluid volume overload doesn’t happen. Includes Brosimine.
HF Medical Mx - Medication: How does Digitalis work?
Digoxin, improves cardiac contractility to help that heart squeeze better
HF Medical Mx - Medication / IV Infusions: What to know for Dobutamine and Milrinone?
They are both inotropes .
HF Medical Mx - Medication / IV Infusions: What does Dobutamine help with?
Helps with contractility , helping heart squeeze better.
HF Medical Mx - Medication / IV Infusions: What does Milrinone help with?
Has a little vasodilation effect. Decreases preload and afterload so heart doesn’t have to work as heard.
HF Medical Mx - Medication / Other Meds: What do Hydralazine and Isosorbide do?
They vasodilate. Can be added if patient has SE from ACE or ARB
HF Medical Mx - Medication / Other Meds: What problems may ACE Inhibitors cause?
Dry cough, angioedema (swelling of upper airway, eyes).
