We will now explain the different terms you may come across in relation to Heart failure (HF).
Disclaimer – from this point onward the module will look only at Left Ventricular Systolic Dysfunction (LVSD) : as this is the condition that the evidence-based guidelines support.

NICE Guideline NG106: Chronic heart failure in adults: diagnosis and management
European Society of Cardiology: Acute and Chronic Heart Failure Guidelines
- Right Heart Failure: Occurs when the right side of the heart is unable to adequately pump blood into the pulmonary circulation. Failure of the right ventricle leads to congestion of the system’s capillaries. This leads to excess fluid accumulation in the peripheries and abdomen. Most common Cause is left heart failure but it can be caused by pulmonary conditions also.
- Left Heart Failure: Occurs when the left side of the heart is unable to pump blood into the systemic circulation. Failure of the left ventricle leads to pulmonary congestion. Most common cause acute myocardial ischaemia, decompensating heart failure….
- Left ventricular systolic dysfunction: Occurs when there is failure of the pumping action of the ventricle leading to a drop in cardiac output (see link to first slide). Over time, the cardiac muscle becomes thin and the heart enlarges Most common causes: Myocardial infarction/ischaemia
- Heart Failure with Preserved function: Occurs when the failure of the relaxation action (diastole) of the ventricle. Over time the cardiac muscle becomes thick and stiff. Most common causes: ageing, previous hypertension. Females are more susceptible
Pulse point
There are many different terminologies describing HF; this can complicate diagnosis, coding and create treatment challenges. You may find it beneficial to look at the guidelines and practices within your area.
