Brief summary

The performance of STIs and clinical scores alone and their combination to predict short term prognosis of acute decompensated heart failure.

Detailed description

Acute heart failure is a leading cause of hospitalization and death.Prediction of these adverse events is still challenging. STI is an old technique based on the recording of two parameters: electrocardiogram and phonocardiogram, and from them measuring the different systolic intervals: pre-ejection period (PEP),electro-mechanic activation time (EMAT), Left ventricular ejection time (LVET) and systolic time ratio (RTS) were measured. The aim of these study is to demonstrate whether systolic time intervals (STIs) can improve clinical scores EFFECT (Enhanced Feedback for Effective Cardiac Treatment) and GWTG-HF (Get With the Guidelines-Heart Failure) for predicting 30 day mortality and readmission in patients with acute decompensated heart failure (ADHF) in the ED.

Interventions

DEVICEbiopac

Acoustic cardiography was performed for all participants using the BIOPAC system with Student Lab software version 3.7.2. An electrocardiogram was obtained by two electrodes placed at the right upper limb and the lower left limb. Simultaneously heart sounds were recorded with a specific sensor placed at the mitral focus.

Effect and GWTGHF were calculated for every patient
