NYHA functional classification of breathlessness
http://www.practicenurse.co.uk/index.php?p1=a-z&p2=shortness-of-breath
Clinical manifestations of L-sided HF include (4):
- Dyspnea!!! MC!
- Pulmonary congestion/edema
- HTN, Cheyne-Stokes breathing (deeper, faster breathing with gradual decrease and periods of apnea)
- Dusky, pale skin. Cook extremities. Fatigue.
Clinical manifestations of R-sided HF include (3):
- Peripheral edema
- JVD
- GI/hepatic congestion- anorexia, N/V
The most useful test to diagnose HF is ______.
Echocardiogram
- EF is the most important determinant (Normal EF 55-60%)
- *EF < 35% = increased mortality :( –> defibrillator placed to reduce mortality
An increased ______ (specific lab value) may identify CHF as the cause for dyspnea in ER.
BNP
*BNP > 100 = CHF likely
____ & ____ are the 2 classes of drugs best for decreasing mortality in pts with CHF.
ACE-I
Beta blockers
Some major side effects of ACE-I include:
HYPERkalemia
Cough
Angioedema
*CI- pregnancy
______ is a safe anti-HTN drug to use during pregnancy.
Hydralazine
_____ (class of drugs) is the most effective treatment for symptom relief in pts with mild-moderate CHF.
Diuretics
*S/E: HYPOkalemia/calcemia/natremia, HYPERglycemia, HYPERuricemia
2 major S/E of sprionolactone are:
- HYPERkalemia
2. Gynecomastia
An example of a sympathomimetic (positive inotrope) that is used in patients with HF + A fib. is: _____.
Digoxin
*Digoxin toxicity- digitalis effect on ECG: downsloping, sagging ST segment
_____ (class of meds) usually not used in systolic HF.
Calcium channel blockers*
*Except angina with HF or normal EF
