AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with atrial fibrillation who are already scheduled for a heart catheter test. It tests new ultrasound methods to estimate pressure in the left ventricle.

Age
18 Years or older
Sex
All sexes can join.
Disease stage
Atrial fibrillation of any kind (paroxysmal, persistent, or permanent).
Earlier treatment
No change in heart medication between the ultrasound and the catheter test.

Main reasons for not taking part

  • Mitral stenosis, or mitral annular calcification causing severe functional stenosis
  • Severe mitral or severe tricuspid regurgitation
  • Prosthetic mitral valve
  • Atrial fibrillation with rapid ventricular response >120 bpm

About the trial

What the trial wants to find out

Heart failure and atrial fibrillation are two of the most common heart diseases globally. Nearly half of all patients with heart failure also have atrial fibrillation. When heart failure and atrial fibrillation occur together, the risk of hospitalization and premature death increases significantly. However, there is a lack of reliable tools to assess how severely the heart is affected in these patients. This makes it difficult both to establish the correct diagnosis, tailor treatment, and predict who is at greatest risk of hospital admission or death from the disease.

One of the most important targets in heart failure is the filling pressure in the left ventricle. When this pressure is high, it means that the heart has difficulty receiving blood, leading to shortness of breath and fluid retention in the body. Today, filling pressure is usually estimated using ultrasound (echocardiography), but the available methods are primarily developed for patients without atrial fibrillation. In patients with both heart failure and atrial fibrillation, the measurements are so uncertain that they cannot be used as a reliable basis for clinical decision-making.

In this study, entitled Heart Failure combined with Atrial Fibrillation (HFcAF), the investigators will test new ultrasound methods that combine novel measures of cardiac chamber function with established techniques. Artificial intelligence will be used to identify the most useful combinations of parameters, select cardiac cycles that are best suited for analysis in atrial fibrillation, and automate and optimize the measurements. This approach may provide both more accurate and faster assessments, while also making the methods easier to implement in clinical practice. The aim is to improve the estimation of filling pressure so that it becomes more precise also in patients with atrial fibrillation. The investigators will then examine whether these improved methods can be used to predict which patients are at highest risk of hospitalization or death due to heart failure.

The study is designed as a prospective multicenter study, in which patients are recruited from several hospitals in different countries. This will make the results robust and generalizable to a wide range of patient populations. The investigators anticipate that the project will pave the way for better diagnostics and risk stratification in heart failure combined with atrial fibrillation and, in the longer term, contribute to improved guidelines and treatment for a large number of patients. If successful, the project will provide a new tool that can contribute to earlier and more targeted treatment, thereby improving quality of life and prognosis for a large group of patients.

The group in the trial

  • Patients with atrial fibrillation referred for right- or left-heart catheterization

    We will recruit patients \>18 years with established or suspected heart failure who have atrial fibrillation and are referred to a diagnostic right- or left-sided heart catheterization or interventional procedures via the left atrium. Balanced numbers with normal and reduced left venticular ejection fraction, balanced representation of sexes, of short (\<1year) and long-lasting duration of atrial fibrillation will be attempted.
