Abstract

Background: Obstructive Sleep Apnea Syndrome (OSAS) is a breathing disorder during sleep. The work was to evaluate the relationship between vasoactive and oxidative stress indicators and cardiac function in Obstructive Sleep Apnea Syndrome (OSAS) patients.

Methods: OSAS patients (n=120) were treated with CPAP from May 2021 to June 2022. According to the clinical efficacy, the patients were divided into effective and ineffective groups. Vasoactive factors and oxidative stress indices were compared between the two groups to evaluate their clinical efficacy. The changes in cardiac function indices in the two groups were tested, and the correlation between vasoactive factors and oxidative stress indices and cardiac function was analysed.

Results: The effective rate of CPAP was 63.33% (76/120). Ang II, ET-1, and MDA levels were lower, and the SOD level was higher in the effective group than in the ineffective group after treatment. The AUC of the four indicators was all greater than 0.75. LPWT and IVST values of the effective group were lower than the ineffective group. A positive correlation was identified between the levels of Ang II, ET-1, and MDA with LPWT, between levels of ET-1 and MDA with IVST, and a negative correlation between SOD with LPWT and IVST.

Conclusions: CPAP treatment can effectively improve vascular activity and reduce the oxidative stress response in OSAS patients, and the combined detection of vasoactive factors and oxidative stress indicators is valuable for evaluating the efficacy of CPAP and is related to the cardiac function of patients.

Uvod: Sindrom opstruktivne sleep apneje (OSAS) je poremećaj disanja tokom spavanja. Cilj ovog istraživanja bio je da se proceni odnos između vazoreaktivnih i pokazatelja oksidativnog stresa i srčane funkcije kod pacijenata sa sindromom opstruktivne sleep apneje (OSAS).

Metode: Pacijenti sa OSAS-om (n=120) su tretirani kontinuiranim pozitivnim pritiskom na disajne puteve (CPAP) od maja 2021. do juna 2022. godine. Na osnovu kliničke efikasnosti, pacijenti su podeljeni u efikasnu i neefikasnu grupu. Vazoreaktivni faktori i pokazatelji oksidativnog stresa su upoređeni između ove dve grupe kako bi se procenila njihova klinička efikasnost. Testirane su promene u pokazateljima srčane funkcije kod obe grupe, a analizirana je i veza između vazoreaktivnih faktora, pokazatelja oksidativnog stresa i srčane funkcije.

Rezultati: Efikasnost CPAP-a je bila 63,33% (76/120). Nivoi Ang II, ET-1 i MDA su bili niži, dok je nivo SOD bio viši u efikasnoj grupi u odnosu na neefikasnu grupu nakon tretmana. AUC svih četiri pokazatelja bio je veći od 0,75. Vrednosti LPWT i IVST kod efikasne grupe su bile niže u poređenju sa neefikasnom grupom. Uočena je pozitivna korelacija između nivoa Ang II, ET-1 i MDA sa LPWT između nivoa ET-1 i MDA sa IVST, i negativna korelacija između SOD sa LPWT i IVST.

Zaključak: CPAP tretman može efikasno poboljšati vaskularnu aktivnost i smanjiti odgovor na oksidativni stres kod pacijenata sa OSAS, a kombinovana detekcija vazoaktivnih faktora i indikatora oksidativnog stresa je dragocena za procenu efikasnosti CPAP-a i povezana je sa srčanom funkcijom pacijenata.
