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.\n\nOne 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.\n\nIn 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.\n\nThe 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.",[321,322],"Heart Failure (HF)","Atrial Fibrillation (AF)",[324,325,326,327,328],"Heart failure","Atrial fibrillation","Echocardiography","Filling pressure","Diastolic function","NOT_YET_RECRUITING","2026-03-03",{"date":332,"type":333},"2026-03-05","ACTUAL",{"date":335,"type":317},"2026-02",{"date":337,"type":317},"2029-12",{"name":5,"class":6},15]
