Abstract

Introduction: Treatment-emergent central sleep apnea (TECSA) is not a rare finding during the follow-up of patients treated with continuous positive air pressure (CPAP) therapy. Clinical predictors and predicting models have been used to identify patients at risk of TECSA.

Aim: To identify patients at risk to develop TECSA after receiving CPAP therapy using echocardiography.

Patients and Methods: Our study included patients who had moderate to severe obstructive sleep apnea (OSA) based on overnight polygraphy admitted to our department from January 2018 to January 2021. All of them received CPAP therapy. All patients have undergone an echocardiographic exam. Data from CPAP devices were analysed periodically to determine those who developed TECSA.

Results: 71 patients met the inclusion criteria. Median follow-up was 24.5 months. 19 patients developed TECSA (26,7%). There was no significant difference in echocardiographic parameters except for left atrial enlargement (p<0.01), left ventricular diastolic dysfunction (98%, p=0,015). HTAP and TECSA are significantly related (p=0,001).

Conclusion: Echocardiography may be an excellent tool to predict TECSA.
