Show Summary Details

Preview

Chronic heart failure (HF) is characterized by exercise intoleranceusually due to breathlessness or fatigue in the presence of cardiac dysfunction.Hence when assessing a patient with such symptoms, inaddition to appropriate cardiac imaging, some form of standardizedexercise testing is important to measure objectively the degree andnature of the symptoms and confirm their aetiology. In addition,exercise capacity is a powerful predictor of mortality and is used as amarker of the need for cardiac transplantation. Although useful datacan be gained from a standard treadmill-based exercise test, or a corridorwalk test, additional and independent information is availablewhen the test is performed while measuring metabolic gas exchange.
