Heart failure (HF) in patients at risk is often overlooked, and when detected, there is a lack of early and effective preventive interventions. The WE-CARE-HF-CMR study, conducted in large cities/metropol areas in Germany ( > 1.000.000 inhabitants), aims to close this gap by evaluating the feasibility of a mobile, telemedicinemonitored HF-screening approach combining cardiac magnetic resonance imaging (CMR), quality of life assessment and laboratory tests as key elements in asymptomatic patients at risk. WE-CARE-HF-CMR will provide a proposal for a comprehensive, contemporary screening approach for patients at risk to develop HF tailored to the needs of the target population. This will provide important new information on the prevalence of asymptomatic HF in at-risk patients in urban versus rural areas.
The results of the study will be compared with the results from the "HERZCheck'' trial, which provides data from approximately 4,500 participants in rural areas in Germany and has already been completed (NCT05122793).
The WE-CARE-HF-CMR-study is a cross-sectional, nationwide prospective, community-based observational study to improve the diagnosis of heart failure in urban populations with characteristic risk factors for the occurrence of heart failure using telemedically-supervised mobile diagnostic units. The central diagnostic methods employed in the assessed screening routine comprise a questionnaire-based medical history, laboratory testing and a standardized, non-invasive imaging examination.
Within the framework of the study, 600 subjects aged 40 to 69 years and of male, female or diverse gender, who have characteristic risk factors for the occurrence of asymptomatic heart failure will be examined.
The central diagnostic imaging method of the study is a standardized, needle- as well as stress- and contrast-agent-free CMR exam. The examinations are carried out in mobile MRI diagnostic units at various clinic locations in 5 major cities (> 1.000.000 residents) in Germany. The various clinics were recommended as locations because they offer good infrastructural conditions for setting up the mobile MRI diagnostic units, which are 27 t truck units, and because emergency medical care for the study participants can also be guaranteed. The medical staff of the clinics is not involved in the study. The potential study participants will be informed by the investigators of the DHZC in a video call either in a room rented specifically for this purpose or in an accompanying vehicle of the mobile MRI diagnostic unit. The consent of the study participants is also obtained via telemedicine and in accordance with current legal requirements in Germany. The planned examinations in the mobile diagnostic unit will be carried out exclusively by the staff of the company operating the MRI units on behalf of and under the telemedical supervision of the investigators and the study management of the DHZC, acting as the central unit.
1,995 studies on the registry are indexed under Renal Insufficiency; 173 are open to participants now.
This study's planned enrollment of 600 is above the median of 149 across 394 observational studies indexed under Renal Insufficiency.

The population from which the groups or cohorts will be selected are asymptomatic adults from the urban areas of Berlin, Cologne, Frankfurt (Main), Hamburg, and Munich with no history of heart failure who have one or more risk factor for developing heart failure. They are either volunteers or referred from local cardiologists.
Asymptomatic subjects with:
