Аннотация
Obstructive sleep apnea syndrome (OSAS) is associated with severe cardiac arrhythmias and conduction abnormalities. Cor pulmonale and right-sided heart failure may ensue. Uvulopalatopharyngoplasty (UPPP) is one of several treatment modalities suggested for OSAS. Tracheotomy and CPAP treatment in adult OSAS patients and adenotonsillectomy in children with OSAS were shown to lead to improvement in some cardiac parameters. Cardiac function was prospectively evaluated in 19 OSAS patients before and after UPPP. No significant changes after surgery were noted on electrocardiographic studies. Improvement in global and regional function of both ventricles was seen in 91% of the patients. A trend toward significant elevation in left ventricular ejection fraction and a statistically significant increase in right ventricular ejection fraction were observed (45% +/- 9% to 50% +/- 7% [p = 0.007]). Our results support performance of UPPP in selected OSAS patients for relief of potentially life-threatening cardiac pathologies.
