Exercise testing aids in diagnosing unexplained dyspnea and pulmonary emboli. Serial testing can track patient recovery, though ventilation-perfusion parameters may not fully normalize.

Area of Science:

  • Pulmonary Medicine
  • Cardiopulmonary Exercise Physiology

Background:

  • Unexplained dyspnea necessitates thorough diagnostic evaluation.
  • Pulmonary embolism (PE) can present with diverse and sometimes subtle symptoms.

Observation:

  • Exercise testing revealed ventilation-perfusion (V/Q) mismatch in a patient with dyspnea.
  • Subsequent investigations confirmed multiple pulmonary emboli.

Findings:

  • Serial exercise testing demonstrated progressive improvement in V/Q parameters during PE treatment.
  • V/Q parameters did not achieve complete normalization despite clinical improvement.

Implications:

  • Exercise testing is a valuable tool for evaluating unexplained dyspnea.
  • Serial exercise testing may offer insights into PE management and recovery monitoring.
