The anaerobic threshold (AT) is defined as the oxygen consumption level above which energy production becomes determined by anaerobic metabolism. This may cause 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 respiratory diseases. This measurement can help clinicians in the functional evaluation of patients and as guidance for rehabilitation and therapy. This chapter will review the pathophysiological aspects and methods of measurement of the AT during a cardiopulmonary stress test, including its clinical use in assessing cardiac and respiratory diseases, with a special focus on the ischemic heart disease.

Abstract
The anaerobic threshold (AT) is defined as the oxygen consumption level above which energy production becomes determined by anaerobic metabolism. This may cause 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 respiratory diseases. This measurement can help clinicians in the functional evaluation of patients and as guidance for rehabilitation and therapy. This chapter will review the pathophysiological aspects and methods of measurement of the AT during a cardiopulmonary stress test, including its clinical use in assessing cardiac and respiratory diseases, with a special focus on the ischemic heart disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
