Comprehensive Clinical Prediction Rule for Acute Heart Failure

August 9, 2026 updated by: Kevin HUNG Kei-ching, Chinese University of Hong Kong

Establishing a Comprehensive Clinical Prediction Rule for the Diagnosis of Acute Heart Failure in the Emergency Department

The goal of this prospective observational cohort study is to establish a comprehensive clinical prediction rule integrating clinical characteristics, point-of-care testing (POCT) of NT-proBNP, an 8-point LUS, and a rapid cardiac assessment using bedside echocardiography for diagnosing acute heart failure (AHF) in the emergency department. A clinical prediction rule with high diagnostic accuracy will minimize delays and misdiagnoses, as well as the potential harm they may cause to patients. The primary outcome measure is the adjudicated AHF diagnosis. Secondary outcome measures include ED and discharge diagnosis of the patients.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adjudicated acute heart failure diagnosis
Time Frame: Immediately after the 6 month follow-up.
The primary outcome for model development and validation will be the adjudicated diagnosis of acute heart failure, as determined by independent review according to ESC criteria.
Immediately after the 6 month follow-up.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Emergency department and discharge diagnosis of the patients
Time Frame: From enrolment to end of review at 6 months.
Secondary outcomes include ED and discharge diagnosis of the patients. A telephone follow-up and chart view at 6 months will be done to ascertain the subsequent diagnosis of AHF.
From enrolment to end of review at 6 months.
