ABSTRACT
BACKGROUND:
Carbon monoxide intoxication and smoke inhalation injury can lead to severe disorders, and the current literature has elaborated on the importance of major cardiopulmonary impairment. Exercise intolerance has seldom been discussed, particular in patient with low cardiovascular risk. CASE PRESENTATION Two young male fire survivors who presented with exercise intolerance after CO intoxication and smoke inhalation injury. Both received bronchodilator and glucocorticoid therapy, high-flow oxygen therapy, and hyperbaric oxygen therapy for airway edema and CO intoxication during acute care. Serum carboxyhemoglobin levels improved after treatment (8.2-3.9% in Case A and 14.8-0.8% in Case B). However, subjective exercise intolerance was noted after discharge. Cardiopulmonary exercise testing revealed exercise-induced myocardial ischemia during peak exercise (significant ST-segment depression on exercise electrocardiogram). They were instructed to exercise with precaution by setting the intensity threshold according to the ischemic threshold. Their symptoms improved, and no cardiopulmonary events were reported in the 6-month follow-up.CONCLUSION:
The present case report raised the attention that exercise intolerance after carbon monoxide intoxication and smoke inhalation injury in low cardiovascular risk population may be underestimated. Cardiopulmonary exercise testing help physician to discover exercise-induced myocardial ischemia and set up the cardiac rehabilitation program accordingly.Palabras clave
