heart failure Flashcards
1
Q
2 categories of heart failure
A
HF with preserved EF and reduced
2
Q
acute decompensated HF occurs when
A
cardiac output fails to meet the bodys needs
3
Q
HF on echo
A
decreased LV and RV function
increased LV and RV size
4
Q
left sided HF leads to
A
congestion behind the failing ventricle
increased pulmonary pressure and congestion
5
Q
left sided HF symptoms
A
SOB while laying down/at night
hemoptysis
pleural effusion
decreased renal function
fatigue and chest pain
6
Q
right sided HF typically follows left sided because of
A
increased pulmonary pressures
7
Q
causes of HF
A
- decreased myocardial contractility
- increased myocardial workload due to hypertension
- filling disorders
- dysrhythmias
8
Q
3 primary components to the compensatory mechanism
A
- chronotrophic froce (HR)
- Inotrophic force (more force)
- ventricular dilation increasing cardiac output
9
Q
complications of HF
A
increased LV and RV pressures
elevated systemic and pulmonary pressures
decreased cardiac output
