Overview
Heart failure hospitalization is associated with a high risk of early readmission and mortality. There is an unmet clinical need for low-burden, non-invasive methods to better understand congestion and hemodynamic status during hospitalization.
This observational study evaluates the association between non-invasive measurements obtained with the Acorai Device 1.0 and clinical data collected during hospitalization and up to 90 days after discharge in patients admitted with heart failure. The device performs short, non-invasive recordings that collect physiological signals from the thoracic region without influencing clinical care.
Participants will undergo daily recordings during hospitalization. Clinical information and outcomes, including heart failure hospitalization and all-cause mortality within 90 days after discharge, will be collected from medical records. The study aims to explore relationships between non-invasive sensor measurements and clinical outcomes in hospitalized heart failure patients.
Description
The Hemodynamic Observational Study in Patients with Heart Failure (HOSP-HF) is a prospective, multicenter observational cohort study conducted in hospitalized patients with a primary diagnosis of heart failure. The study is designed to evaluate associations between non-invasive physiological measurements obtained using the Acorai Device 1.0 and clinical parameters and outcomes.
The Acorai Device 1.0 is a non-invasive, handheld system that records multimodal thoracic signals during brief recordings of approximately five minutes. The device does not provide diagnostic output to clinicians and does not influence clinical management.
Eligible patients admitted with new or worsening heart failure will be enrolled during hospitalization. Participants will undergo daily non-invasive recordings with the device from admission until discharge. No additional diagnostic or therapeutic procedures are introduced by the study.
Clinical information including demographics, medical history, vital signs, laboratory values, and routine imaging findings will be collected from medical records where available. Outcomes including heart failure hospitalization and all-cause mortality will be assessed for 90 days following discharge from the index hospitalization.
The primary objective of the study is to assess the association between non-invasive sensor measurements and the composite outcome of heart failure hospitalization or all-cause mortality within 90 days after discharge. Exploratory analyses will evaluate changes in device measurements during hospitalization and their relationship with clinical parameters and outcomes.
The study is conducted at hospitals in the United States, Europe, and Singapore.
Eligibility
Inclusion Criteria:
- Age ≥18 years
- Hospitalization for primary heart failure, defined as new or worsening heart failure symptoms with objective evidence of congestion requiring initiation or intensification of heart failure-specific therapy
- Ability to provide written informed consent
Exclusion Criteria:
- Any discretionary exclusion where the inclusion of the subject is deemed to pose potential risks to the subject's well-being or is likely to comprise the compliant performance of the study.
- Pregnancy or lactation (as confirmed by self-report or medical documentation)
- Presence of a skin rash or open wound in the area where the Acorai Device model 1.0 will be applied
- Any other condition that, in the opinion of the investigator, would preclude the subject from participating in the study or may affect the integrity of the data
