Systolic congestive heart failure: what to know

Systolic refers to contraction, the phase when the ventricles push blood out. When this action is weaker, the body may receive less blood flow and pressure can build behind the heart, causing fluid to collect in the lungs or lower legs. Heart failure does not mean that the heart has stopped; it describes a long-term change in how well it fills or pumps.

People may notice breathlessness, tiredness, a cough, a racing or irregular heartbeat, or swollen ankles. Atrial fibrillation and hypertension can coexist with heart failure and may affect the assessment.

Arrange a clinical assessment if these symptoms are new, persistent or changing. Evaluation may include an examination, blood tests, an electrocardiogram and an ultrasound scan of the heart. Treatment is tailored to your heart function, blood pressure, kidney health, other conditions and current medicines.

Take prescribed medicines as directed, keep follow-up appointments and discuss changes in breathlessness, weight, swelling or exercise ability. A chronic disease review can help check symptoms, medicines and self-care together. Do not stop heart medicines suddenly without medical advice.

Seek emergency help for severe or rapidly worsening breathlessness, chest pressure, fainting, new confusion, or blue-grey lips. Sit upright while waiting and follow any personal emergency plan. Contact a clinician promptly if ankle swelling, cough or fatigue is steadily worsening or you cannot do usual activities.

Ask which part of the heart is affected, what your scan shows, how to take each medicine, and which changes should prompt a same-day call. You can also ask whether atrial fibrillation or hypertension needs separate treatment.
