Predicting impaired cardiopulmonary exercise capacity in patients with atrial fibrillation using a simple echocardiographic marker
Authors' conclusion
In patients with AF, LA/LVEDD is strongly associated with exercise capacity.
Study context
- Population
- Patients with AF undergoing echocardiography and cardiopulmonary exercise testing at a tertiary AF centre, 2020–2022; valvular heart disease, reduced LVEF or cardiomyopathy excluded
- Participants
- 188 patients
- Outcome
- Association between echocardiographic parameters and exercise capacity by cardiopulmonary exercise testing
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
- Impaired exercise capacity (peak oxygen consumption ≤85%)
- 134 (71.2%)
- Poor exercise capacity (peak oxygen consumption <50%)
- 4 (2.1%)
- LA/left ventricular end-diastolic diameter (LVEDD) the only significant echocardiographic parameter in multivariate model (adjusted for age, sex, BMI)
- P = .020
Observational data: associations, not effects.
