Heart Failure
Types
- Left-sided heart failure
- Right-sided HF
- High-output failure
- Low-output failure
- Systolic dysfunction
- Diastolic dysfunction
Left-sided heart failure
- Failure of left ventricle, back flow into lungs
Right-sided HF
- Failure of right side of heart, back flow into systemic venous system
High-output failure
- Severe renal dysfunction
- Kidneys cant filter, heart cant keep up
- Secondary to renal system failure to filter
Low-output failure
- Heart cannot pump minimum amount to support circulation
Systolic dysfunction
- Problem with systole or strength of contraction
Diastolic dysfunction
- Problem with diastole or ability of ventricle to allow filling
Congestive Heart failure
Signs of CHF
- Cold, pale, possibly cyanotic extremities
- Weight gain- heart fialure that is progressing, more fluid in system
- Peripheral edema
- Jugular venous distention
- Crackles (rales)
- Sinus tachycardia
- Decreased exercise tolerance
Symptoms of CHF:
- Dyspnea
- Tachypnea
- Paroxysmal nocturnal dyspnea
- Severe SOB that wakes them from sleep
- Orthopnea
- Lying flat = SOB
- Cough
- Fatigue
