CV System and Disorders: Week 4: Set 3 Flashcards
What is done to diagnose HF
- Coronary angiogram
- TSH-thyroid
- CBC
- Chemistry profile
- BMP (basic metabolic profile)
- Magnesium
- Check BNP (brain neutropenic protein)
- EKG
- Echocadiogram
- Chest Xray
Why is a coronary angio done for diagnosing HF? Who does it?
- Can’t figure out etiology
2. Cardiologist
Why is TSH levels read for diagnosing HF?
hyperthyroid > aFib> HF
Why is CBC read when diagnosing HF?
anemia
Why is magnesium read when diagnosing HF?
can cause cardiac arrhythmias
Why is BNP read when diagnosing HF?
Elevated in HF pts
Why is chest xray read when diagnosing HF?
- Visualize heart and lungs
2. See if pleural effusion or enlarged heart
what are AHA and ACC(1-4) AND NYHA (A-D)? What do they do?
- systems to classify HF
- so they know who can get heart transplants
- Higher is worse (4 and D)
Maintenance of Cardiac Reserve in HF: Compensatory and Adaptive Mechanisms
- Activation of SNS, RAAS
2. Activation of inflammatory mediators
What does activation of SNS, RAAS as a compensatory/adaptive mechanism for HF do to help?
- Maintain cardiac output through….
- increased retention of salt and water
- peripheral arterial vasoconstriction
What does activation of inflammatory mediators as a compensatory/adaptive mechanism for HF do to help?
involved in cardiac repair and remodelling
EF in systolic and diastolic HF
Systolic-Low EF
Diastolic-EF-60%
Which disorders start with right HF with progression to left HF?
COPD and cor pulmonale
Which disorders start with left HF with progression to right HF?
CAD
Acute vs chronic HF
Acute-occurs very suddenly, medical emergency
Chronic- develops gradually over time
- Paroxysmal Nocturnal Dyspnea
- Pulmonary congestion
- Restlessness
4, Confusion - Orthopnea
- Tachypnea
- Exertional dyspnea
- Fatigue
- Cyanosis
Left HF S&S
- Fatigue
- increased peripheral venous pressure
- Ascites
- Enlarged liver/spleen
- Secondary to pulmonary problems
- JVD
- Anorexia/GI distress
- Weight gain
- Edema
Right HF S&S
Systolic HF vs Diastolic HF
Systolic-left ventricle can’t contract completely
Diastolic- left ventricle can’t fill properly
Condition caused by excess fluid in the lungs. This fluid collects in the numerous air sacs in the lungs, making it difficult to breathe.
Pulmonary Edema
Types of Circulatory Shock
Hypovolemic Shock Cardiogenic Shock Obstructive Shock Distributive Shock Septic Anaphylactic Neurogenic
Circulatory Shock caused by insufficient circulating volume
Hypovolemic Shock
Circulatory Shock caused by a failure of the heart to pump correctly
Cardiogenic Shock
Circulatory Shock caused by an obstruction of blood flow outside of the heart (usually venous)
Obstructive Shock
Circulatory Shock caused by an abnormal distribution of blood to tissues and organs.
Distributive Shock
Distributive Shock is broken into 3 types of shock. what are they?
Septic
Anaphylactic
Neurogenic
How does Septic Shock occur?
- Systemic infection that cannot be cleared by the immune system
- Vasodilation and hypotension
How does Anaphylactic Shock occur?
- Reaction to allergen
- Release of histamine
- Vasodilation and hypotension
How does Neurogenic Shock occur?
- Damage to the CNS
- Impairs cardiac function by reducing HR and loosening the blood vessel tone
- Severe hypotension
- Cardiopulmonary arrest
- Dysrhythmia
- Renal failure
- Multisystem organ failure
- Ventricular aneurysm
- Thromboembolic sequelae
- Stroke
- Death
Complications of circulatory shock
Infants & Children with HF from what?
Heart damage
Rare self-limited vasculitis, most often affects kids younger than 5 years old.
Kawasaki Disease
Why is it best to be noticed ASAP?
can lead to all kinds of complications
