|Title:||Effect of duration of data averaging interval on reported peak VO₂ in patients with heart failure||Contributor(s):||Smart, Neil (author) ; Short, Leanne (author); Giallauria, Francesco (author); Vigorito, Carlo (author); Vitelli, Alessandra (author); Maresca, Luigi (author); Ehrman, Jonathon K (author); Keteyian, Steven J (author); Brawner, Clinton A (author)||Publication Date:||2015||DOI:||10.1016/j.ijcard.2014.12.174||Handle Link:||https://hdl.handle.net/1959.11/17204||Abstract:||Aim: To describe the effect of the duration of the data averaging interval on the calculated peak oxygen uptake (VO₂) reported from a symptom-limited maximal exercise test in patients with heart failure. Methods: Maximal exercise test results from 275 patients diagnosed with stable heart failure due to left ventricular systolic dysfunction (ejection fraction < 45%; age: 45-75 years; peak VO₂: 8.0-20.0 mL/kg/min), were examined. Sampling rates of 10, 20, 30 and 60 s were used to calculate peak VO₂, which was identified as the highest interval value that occurred during the final minute of exercise or the first interval in immediate recovery. ... Conclusions: Sampling rate method has a significant effect on calculated peak VO₂ and RER. We suggest that laboratories standardize their sampling rate method to ensure consistency.||Publication Type:||Journal Article||Source of Publication:||International Journal of Cardiology, v.182, p. 530-533||Publisher:||Elsevier Ireland Ltd||Place of Publication:||Ireland||ISSN:||1874-1754
