Terminology can sometimes be confusing in heart failure care.
Here is a summary:
NYHA I = No limitation in physical activity; no symptom
NYHA II = Slight limitation in physical activity; symptoms with ordinary activity
NYHA III = Marked limitation in physical activity; symptoms with less than ordinary activity
NYHA IV = Unable to carry on any physical activity; symptoms at rest
HF by ejection fraction
HF with reduced EF (HFrEF) = LVEF <50%
HF with preserved EF (HFpEF) = LVEF >50%
HFrEF has evidence based therapy - ACEi, ARB, bB, MRA, Sacubitril
HFpEF does not have evidence based therapy, aim for anti-HT.
Stage A HF = high risk for developing HF
Stage B HF = asymptotic LV dysfunction
Stage C HF = past or current symptoms of HF
Stage D HF = end stage HF
