This congestion does not necessarily justify a hospitalization and for part of the patients a consultation and a dedicated treatment would be good enough to cure the symptoms.\n* Thus, patients seen in emergency for a congestion and diagnosed or known to have a preserved left ventricular ejection fraction (LV EF \\> 45%) will be proposed to participate to the study.\n* Patients meeting inclusion criteria will be invited back to the clinic in stable condition, approximately 4-8 weeks after the initial hospitalization.\n* Time 4-8 weeks after initial hospitalisation (NOT after discharge): Comprehensive history-taking and examinations.\n* Any information necessary for the study will be collected by the principal investigator in each participating center in a dedicated, secure, e-CRF. The access to the e-CRF will be restrictive to the only principal investigator of each center. The lonely other persons able to take look to the e-CRF are the study monitors.\n* Time 6, 12, and 18 months: Follow up by phone call or review of charts or other records such as death registries.
