Background And Purpose:
Obstructive sleep apnea syndrome (OSAS) is regarded as a cardiovascular risk factor. Therefore, cardiopulmonary exercise capacity in patients with OSAS before and under treatment with continuous positive airway pressure (CPAP) was investigated.
Patients And Methods:
Cardiopulmonary exercise capacity was investigated in 36 patients with untreated OSAS using spiroergometry. A follow-up after at least 6 months was performed in 17 of these patients being treated with CPAP and in eight CPAP-neglecting patients, who served as controls.
Results:
Maximum oxygen uptake (
Conclusion:
Cardiopulmonary exercise capacity is markedly reduced in patients with OSAS. Long-term CPAP therapy leads to a significant improvement of reduced cardiopulmonary exercise capacity in these patients.
