[Ten questions about cardiopulmonary exercise testing: all that the cardiologist dares or dares not to ask]

Area of Science:

• Cardiology
• Pulmonology
• Neurology
• Exercise Physiology

Background:

• Cardiopulmonary exercise testing (CPET) is crucial for evaluating exercise response in patients with cardiovascular, pulmonary, muscular, and neurological diseases.
• It provides clinically relevant diagnostic and prognostic information, aiding in disease management and understanding exercise intolerance.

Purpose of the Study:

• To explain the everyday applications and potential future uses of CPET in clinical practice.
• To serve as a resource for physicians new to CPET and those seeking to expand their knowledge.

Main Methods:

• Review of clinical applications and scientific literature on CPET.
• Focus on the diagnostic and prognostic capabilities of CPET beyond standard exercise electrocardiography.

Main Results:

• CPET accurately grades disease severity and differentiates causes of dyspnea and exercise impairment.
• It is essential in managing heart failure, pulmonary hypertension, and selecting heart transplant candidates.

Conclusions:

• CPET is a safe and valuable tool offering extensive pathophysiological information.
• Its clinical indications are expanding, highlighting its growing importance in patient care and research.
