Abstract
Cardiopulmonary exercise testing (CPET) is a crucial tool for assessing cardiorespiratory function, providing invaluable insights into individual physiological capacities. This review explores the clinical indications of CPET, its contraindications, as well as a comprehensive protocol for its execution. Additionally, it highlights key parameters measured during CPET and their interpretation, as well as the role of CPET in the prescription of aerobic training in cardiac rehabilitation. This review aims to provide a comprehensive, up-to-date synthesis of advances in the field of CPET and their clinical implications.
