Key Result

An e'AT value of <6.0 cm/s predicts 1-year outcomes in elderly heart failure patients, serving as a robust prognostic marker.

Key Points

To determine if diastolic function at the anaerobic threshold can predict one-year outcomes in elderly heart failure patients.
Used CPET-SE (Cardiopulmonary Exercise Testing with Strain Echocardiography) to measure diastolic function
CM measurements were correlated with one-year clinical outcomes
Evaluated the prognostic value of e'AT within the studied population
An e'AT value of <6.0 cm/s is a robust prognostic marker in older heart failure patients
The study indicates that incorporating diastolic function improves traditional risk stratification
CPET-SE shows potential as an adjunct tool alongside conventional assessments

Structured PICO

Does an e'AT value <6.0 cm/s derived by CPET-SE predict 1-year outcomes in elderly patients with heart failure?

Population

Elderly patients with heart failure

Intervention

e'AT value <6.0 cm/s derived by Cardiopulmonary Exercise Testing - Stress Echocardiography (CPET-SE)

Outcome

1-year outcomes

An e'AT value <6.0 cm/s during CPET-SE serves as a robust prognostic marker for 1-year outcomes in elderly heart failure patients, complementing standard risk stratification tools.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

An e'AT value of <6.0 cm/s derived by CPET-SE is a feasible and robust prognostic marker in older patients with HF. CPET-SE may be an adjunct tool for risk stratification, complementing conventional biomarkers, echocardiography, and CPET parameters.
