Q

What is Acute pulmonary edema?

A
  • Acute intense shortness of breath – Occurs once fluid retention / left atrial pressure overwhelms compensatory mechanisms (e.g. lymphatic fluid return) – Fluid spills from the pulmonary vasculature into the interstitial space and then into the alveoli, producing hypoxia – Increase vascular prominence on CXR first, followed by “fluffy” infiltrates

Q

What is a right heart catheterization?

A

A plastic catheter introduced into one of the major veins and then “floated” through the right heart into the pulmonary artery - Has a balloon on the end of it to help blood flow carry it into the lungs - The balloon also allows a branch of the pulmonary artery to be occluded so that the downstream pressure (post-capillary wedge pressure [PCWP]) can be measured, which is equivalent to the left atrial pressure / left-sided filling pressure.

17
Q

What is the mitral/tricuspid valve closure?

18
Q

What is an echocardiogram?

A

an ultrasound of the heart

19
Q

What is cachexia?

20
JVP = ____ = right atrial pressure
CVP
21
What is NT-proBNP?
the N-terminus breakdown product of BNP that is increased with age and esp renal failure
23
Name 5 signs of elevated L-sided filling pressures.
1. rales (pulmonary crackles) 2. hypoxia 3. tachypnea 4. sitting bolt upright 5. popping open of alveoli
25
What are rales? What causes them?
pulmonary crackles- sounds like velco being pulled apart upon inspiration- due to wet alveoli opening
26
When is an S3 gallop normal? Abnormal?
normal: young people abnormal: after age 30
27
Increased pulmonary venous pressure causes what symptom of HF?
breathlessness
28
What is immediate SOB when lying flat because of lost venous pooling of blood in the legs?
orthopnea
29
What is the aortic/pulmonary valve closure?
S2
30
What is the test that is a gross measure of systolic function?
left ventricular ejection fraction (LVEF)
32
What are the 3 major pathophys causes of HF?
1. decreased cardiac output 2. increased pulmonary venous pressure 3. increased central venous pressure
34
An _____ is thought to be caused by rapid expansion of the ventricular walls in early diastole.
S3 gallop
36
Increased R sided filling pressure causes?
• Peripheral swelling / dependent edema • Ascites • Hepatic congestion • Intestinal congestion (protein-losing enteropathy)
37
With a person \_\_\_\_\_, the jugular vein (internal and external) fill with blood. Thus the neck veins will appear full on visual examination. More importantly, they will transmit pressure changes in the right atrium as waves.
lying flat or with JVD in HF
38
Normal JVP is \_\_\_\_.
\< 5 cm H2O
38
With a person lying flat or with JVD in HF, the jugular vein (internal and external) fill with blood. Thus the neck veins will appear full on visual examination. More importantly, they will transmit _____ in the _____ as waves.
pressure changes; R atrium
39
JVP = CVP = \_\_\_\_\_
right atrial pressure
40
What is Paroxysmal nocturnal dyspnea (PND)?
– Delayed SOB, waking patients from sleep – Classically patient gets out of bed and ambulates to relieve symptoms – Relates to mobilization of edema from tissue through lymphatics back into blood stream
40
When is an S4 gallop typical?
never
42
What EKG findings will be seen in HF?
no direct diagnosis- would infer from other findings, like Q wave abnormalities (prior MIs), increased voltage (LVH), arrhythmias, diffuse conduction
43
What will be found on a chest xray in HF?
- enlarged cardiac silhouette in HFrEF - increased upper lobe vascular markings with acute decompression - fluffy infiltrates of PE - plural effusions
45
What are two assays used to detect natriuretic peptides in HF?
1. BNP 2. NT-proBNP
46
What is Orthopnea?
Immediate SOB when lying flat because of lost venous pooling of blood in the legs
47
Increased central venous pressure causes what symptom of HF?
edema
48
What tests are used to diagnose HF?
Chest Xray natriuretic peptides EKG cardiac imaging
49
Does a low BNP or NT-proBNP rule in or rule out HF?
it would rule out- high is not necessarily diagnostic
