Systolic heart failure and ejection fraction

The left ventricle fills with blood and then contracts. An echocardiogram estimates how much of that filled blood is expelled with each contraction. A reduced result supports a diagnosis of reduced systolic function, but the number is only one part of the picture. Symptoms, examination findings, valve function, heart rhythm and other scan details also matter.

Ejection fraction can change over time, and people with a similar result may have different symptoms. Breathlessness, fatigue, cough or ankle swelling should therefore be discussed even if a previous result sounded reassuring.

Ask which ventricle was measured, how reliable the scan was and what the result means alongside your symptoms. Your clinician may arrange repeat imaging when there is a clinical reason. Treatment can include medicines and management of blood pressure, rhythm, valves or fluid balance, depending on the whole assessment.

Take medicines as prescribed and report dizziness, worsening breathlessness, new palpitations or increasing swelling. Bring prior scan reports to appointments when available. A chronic disease review can help connect the measurement with day-to-day function and the treatment plan.

Call emergency services for severe breathlessness at rest, chest pressure, fainting, collapse or blue-grey lips. Seek prompt medical advice if symptoms suddenly change, you develop a sustained racing or irregular heartbeat, or swelling and breathlessness are progressing.

Ask what your ejection fraction indicates, whether it has changed, what other scan findings matter, and when it should be checked again. Ask which symptoms reflect fluid retention and which warrant urgent assessment.
