Cardiopulmonary exercise test

Cardiopulmonary exercise test (CPET), also known as cardiopulmonary exercise testing, is a non-invasive diagnostic assessment that assesses the combined performance of the cardiovascular, respiratory, and musculoskeletal systems during physical exercise.[1] First developed in the early 20th century, CPET has become a gold-standard method for evaluating cardiorespiratory function.[2] It is widely used to measure exercise tolerance, diagnose cardiopulmonary diseases and guide individualized treatment plans for patients.[3]

During the test, key physiological parameters, including heart rate, blood pressure, oxygen consumption and ventilation patterns are continuously monitored while the patient performs graded exercise of increasing intensity, typically on a treadmill or cycle ergometer.[4][5] Advanced data analysis is an essential component of CPET, enabling clinicians to interpret the body's response to physical stress and detect abnormalities that may not be evident at rest.[1]

However, CPET may not be suitable for high-risk patients, such as those recovering from a recent heart attack (myocardial infarction) or experiencing acute respiratory failure.[3] Despite these contraindications, CPET remains widely utilized in clinical practice, and when combined with other tools, new applications continue to emerge.[6]
