The usefulness of the anaerobic threshold in the assessment and prognostic evaluation of the patient with dyspnea.

Abstract

The anaerobic threshold (AT) is defined as the oxygen consumption level above which energy production becomes determined by anaerobic metabolism, which causes a sustained increase in lactate and metabolic acidosis. The AT, as measured by cardiopulmonary stress testing, is ubiquitously used to determine the prognosis and diagnosis of cardiovascular and… (More)
