Heart failure - Definitions

Terminology can sometimes be confusing in heart failure care.

Here is a summary:

NYHA classes

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, Empagliflozin

HFpEF does not have evidence based therapy, aim for anti-HT.

HF stages

Stage A HF = high risk for developing HF —> address risk factors

Stage B HF = asymptotic LV dysfunction, i.e. pre-heart failure

Stage C HF = past or current symptoms of HF

Stage D HF = end stage HF; repeated hospitalisations
