Demographic, Clinical, Biological, Treatment Characteristics and Cardiovascular Events of Patients With Heart Failure in Vietnam: a Multicenter Prospective Observational Study

Recruiting

• Conditions: Heart Failure With Mid Range Ejection Fraction; Heart Failure; Heart Failure With Reduced Ejection Fraction
• Interventions: Drug: Optimal treatment

• Registration Number: NCT06516562
• Lead Sponsor: University Medical Center Ho Chi Minh City (UMC)

Brief Summary

Describe the clinical characteristics, paraclinical features, and treatment during hospitalization, as well as at 1, 3, and 12 months post-discharge, of heart failure patients at selected cardiovascular centers in Vietnam.

Detailed Description

Study Design: Prospective cohort study

Study Subjects: Patients discharged with a diagnosis of heart failure with reduced or mildly reduced ejection fraction.

Inclusion Criteria:

* Patients aged 18 years and older

* Diagnosed with heart failure at the time of discharge

* Have an ejection fraction (based on imaging modalities such as echocardiography or cardiac MRI) recorded closest to the time of discharge, showing a left ventricular ejection fraction of less than 50%

Exclusion Criteria:

* Patients and their relatives do not have means of communication with healthcare staff (phone, computer, messaging, etc.)

* Patients do not reside in Vietnam after discharge

Data Collection:

* All patients meeting the criteria at the time of discharge during the study period will be continuously included. Information regarding demographic data, clinical presentation, biological markers, and in-hospital treatment characteristics will be collected using standardized data definitions from EuroHeart data standards for heart failure.

* Periodically after hospital discharge (e.g., 1 month, 3 months, 12 months post-discharge), patients will be contacted by investigators to gather information on their current status, medications, and any cardiovascular events, including rehospitalizations, death, and current medical treatment.

* Data entry will be performed using the REDCap project at the University of Medicine and Pharmacy, Ho Chi Minh City (https://redcap.umc.edu.vn/)
