简要总结

The purpose of this study is to examine electrical and echocardiographic characteristics and prognosis of consecutive patients admitted with acute heart failure and diagnosed to have heart failure with preserved ejection fraction (HFPEF).

详细描述

  • Time 0: Patients will be screened at the time of presentation to the hospital at participating centres
  • Usually patients will be hospitalised for an acute dyspnea in relation with a pulmonary congestion. 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.
  • 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.
  • Patients meeting inclusion criteria will be invited back to the clinic in stable condition, approximately 4-8 weeks after the initial hospitalization.
  • Time 4-8 weeks after initial hospitalisation (NOT after discharge): Comprehensive history-taking and examinations.
  • 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.
  • Time 6, 12, and 18 months: Follow up by phone call or review of charts or other records such as death registries. This part of the study will be performed by the CRAs in the French Society of Cardiology
