274 consecutive heart failure patients with left ventricular ejection fraction ≤ 40% were prospectively evaluated. The dataset likely contains cardiopulmonary exercise test parameters used to stratify risk for cardiac death or urgent heart transplantation over a 1-year follow-up. It was created by António Valentim Gonçalves and is available via Open Access.
Use Cases
- Predicting composite outcomes of cardiac death or urgent heart transplantation based on CPET parameters.
- Evaluating the predictive value of pVO2 cut-offs for heart transplantation selection in atrial fibrillation patients.
- Comparing risk stratification performance of CPET parameters between atrial fibrillation and sinus rhythm patient groups.
- Analyzing the prognostic significance of VE/VCO2 slope values in high-risk heart failure patients.
Strengths
- 274 patient records with a defined primary endpoint over a 1-year follow-up.
- Specific predictive values (PPV and NPV) for key CPET parameters are reported in the description.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect temporal or source bias inherent to paperswithcode.
