EXERCISE TESTING OF HEART FAILURE PATIENTS WITH RESPIRATORY BREATH ANALYSIS – A REVIEW OF CURRENT TRENDS
Journal Title: Medicina Sportiva - Year 2013, Vol 17, Issue 2
Abstract
Objective: To highlight current trends in cardio-respiratory exercise testing of patients diagnosed with heart failure.Methods: Measures of cardio-respiratory performance, namely maximum oxygen uptake, ventilatory efficiency, and oxygen uptake efficiency, are compared. Their utility is discussed with reference to the routine assessment of patients. Selected articles which report the use of cardio-respiratory testing in clinical populations, and selected articles which clearly show the benefit of using respiratory gas analysis in determining prognosis of heart failure, were used to construct the review.Results: Data indicating the improved survival of heart failure patients with preserved cardio-respiratory efficiency are reported. We also present data which report the prognostic superiority of measures of cardio-respiratory efficiency when compared to peak oxygen uptake.Conclusions: The physiological determinants of the measures are briefly discussed. Based on the improved prognostic capacity of measures of cardio-respiratory efficiency, the review favours the inclusion of cardio-respiratory testing in the routine clinical assessment of heart failure patients.
