From the Guidelines
Echocardiograms should be performed in heart failure patients at diagnosis, when there is a significant change in clinical status, and typically every 1-2 years for stable patients, as recommended by the most recent guidelines 1. The initial echocardiogram is crucial in establishing baseline cardiac function, identifying the type of heart failure, and determining underlying causes.
- At diagnosis, an echo assesses left ventricular ejection fraction (LVEF), diastolic function, chamber size, ventricular wall thickness, valvular abnormalities, and hemodynamic parameters, including estimated right ventricular systolic pressure, central venous pressure, and LV filling pressures 1.
- Follow-up echos should be conducted whenever patients experience worsening symptoms, hospitalization for heart failure, or after starting new heart failure therapies to assess treatment response.
- For clinically stable patients, routine surveillance echocardiography every 1-2 years is reasonable to monitor disease progression and guide therapy adjustments, as suggested by previous guidelines 1. More frequent monitoring (every 3-6 months) may be appropriate for patients with advanced heart failure, those being evaluated for advanced therapies like transplantation, or patients with devices requiring optimization, as indicated by the latest update 1. The timing should be individualized based on clinical stability, treatment changes, and specific patient factors such as valvular abnormalities or cardiomyopathies that may warrant closer monitoring.
From the Research
Echocardiogram Frequency in Heart Failure Patients
- The recommended frequency for performing echocardiograms in patients with heart failure is not explicitly stated in the provided studies, but some studies offer guidance on the timing of echocardiography in relation to patient management and outcomes 2, 3.
- A study from 2000 suggests that echocardiographic follow-up of patients with heart failure and left ventricular systolic dysfunction should include analysis of changes in left ventricular function and dimension during follow-up, with assessments at 3 to 6 months, 12 to 24 months, and serial examinations according to the stage of the disease or episodes of worsening heart failure 2.
- Another study from 2018 recommends that a transthoracic echocardiogram (TTE) be performed before discharge in patients admitted for heart failure, as it provides more information on prognosis in both heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) 3.
- The use of echocardiography in conjunction with other diagnostic tools, such as B-type natriuretic peptides, can provide powerful incremental assessment of cardiac function, clinical status, and outcome across the spectrum of cardiac disease 4.
- Echocardiography is an essential investigation in patients with suspected heart failure, providing diagnostic information about the cause of heart failure, guiding further investigations and therapy, and offering important prognostic information 5, 6.
