CHEST 2023 On Demand Pass-Cardiopulmonary Exercise Testing Pearls: Case-Based Interactive Session

Video Transcription

Video Summary

In this video, three cases of patients undergoing cardiopulmonary exercise testing (CPET) are presented. In the first case, a patient with obesity and exertional dyspnea undergoes CPET to determine the cause of their symptoms. The CPET reveals normal cardiovascular function and exercise efficiency, but it is noted that obesity can affect pulmonary mechanics, including dynamic hyperinflation and increased airway resistance. The second case involves a patient with long-haul COVID who experiences fatigue and dyspnea during exercise. The CPET shows reduced exercise capacity and signs of cardiovascular dysfunction, leading to further investigations that reveal significant coronary artery disease. The third case involves a patient with amyloidosis and suspected upper airway obstruction. The CPET reveals evidence of central airway obstruction, but no significant cardiovascular or pulmonary abnormalities. Ultimately, this patient's symptoms are attributed to deconditioning rather than the amyloidosis. The importance of CPET in diagnosing and monitoring patients with various conditions is highlighted in these cases.
