Abstract

To evaluate the effect of continuous positive airway pressure (CPAP) therapy on pro-brain natriuretic peptide (BNP) and cardiac markers in patients with obstructive sleep apnea syndrome and normal cardiac function. Thirty-three consecutive patients with sleep apnea syndrome were analysed for serum pro-BNP and cardiac markers prior to and after 6 months of CPAP therapy. Twenty five patients had normal (83.3%) while remaining five (16.7%) revealed high pro-BNP values. We did not detect any significant difference between severity of obstructive sleep apnea syndrome and serum pro-BNP levels (p = 0.534). A statistically significant difference was not observed between basal and sixth-month creatine kinase (CK), creatine kinase-MB (CK-MB), troponin I, pro-BNP, aspartate transaminase (AST), and CK levels in patients with sleep apnea syndrome (p > 0.05). Obstructive sleep apnea syndrome does not induce myocardial damage enough to increase serum pro-BNP, CK, CK-MB, troponin I, and AST levels. Markers sensitive to ischemia could be preferred to evaluate effect of obstructive sleep apnea syndrome.
