Flashcards in Congestive Heart Failure Deck (10):
1

True or false: CHF is the end point of serious heart disease?

True.

2

What is meant by "congestion" in the heart, pulmonary circuit and systemic circulation in CHF?

"Pooling" of blood

3

What is the etiology of CHF?

MI
Cardiomyopathy
Excessive cardiac workload
Valvular disease
Hypervolemia
Uncontrolled HTN

4

What are risk factors for CHF?

HTN
Smoking
Hyperlipidemia
Diabetes mellitus
Ischemic heart disease
Obesity
Age

5

What does congestion leads to in CHF? And why does it result?

It leads to edema as a result of an increased hydrostatic pressure in circulation

6

What is the patho physiology of left sided heart failure?

LV does not eject sufficient volume - residual volume in LV - LA pumps harder to empty blood into LV - LA fails to fully empty - LA unable to receive full pulmonary return - pulmonary congestion and edema - RV workload increases - RV hypertrophys

7

What is a manifestation of left sided heart failure?

Pulmonary congestion and edema
Frothy sputum (due to gas mixing with liquid)
Decreased cardiac output

8

What are manifestations of right sided heart failure?

Peripheral edema
Abdominal organ distension

9

What is the patho physiology of right sided heart failure?

The RV is unable to pump sufficient volume into pulmonary circulation - congestion in RV - RA unable to fully empty into RV and works hard to push blood into RV - systemic circulation does not empty properly into RA - congestion and edema occur in systemic circulation due to increased hydrostatic pressure

10

True or false: CHF is a disease.

False.
It is a group of manifestations.
