OBSTRUCTIVE SLEEP APNEA SYNDROME PRIOR TO STROKE: A RISK STRATIFICATION STUDY

Introdução

The prevalence of obstructive sleep apnea syndrome (OSAS) in the general population is 3-7%, while the prevalence of OSAS in patients who have had stroke is 30 to 70%. Since stroke affects 16.9 million people each year and is the second leading cause of death worldwide, prevention of its risk factors such as systemic arterial hypertension is important. Since OSAS is an under diagnosed risk factor for stroke and an independent risk factor for hypertension, which increases the risk for stroke by 3 to 4 times, the aim of this study was to apply validated scales in the literature for OSAS screening.

Objetivo

To evaluate the presence of OSAS through the STOP-BANG and SOS score questionnaires in patients with ischemic stroke.

Métodos

Cross-sectional study. The study population consisted of individuals over 18 years of age, after acute stroke in the Hospital Nossa Senhora da Conceição, from September 2018 to February 2019 in the city of Tubarão - SC. Data were obtained through the application of STOP –Bang and SOS score scales, and a questionnaire on socio-demographic profile prepared by the researchers was also applied. In addition, the area affected by stroke was evaluated through the first imaging exam performed after the patient's admission to the hospital.

Resultados

50 patients participated in this study and what could be observed was that the prevalence of OSAS risk by SOS score was 80%. According to the STOP-Bang scale, 70% of the patients were classified as high risk and 24% as intermediate risk. The percentage of men who were at high risk for OSAS by the SOS score was 17.8% and women 22.7%. On the STOP-Bang scale, 85.7% for males and 50% for females for OSAS risk. The relationship between systemic arterial hypertension (HAS) and risk of sleep apnea was high on both scales.

Conclusões

It was concluded that the studied population had a high risk of OSAS assessed by STOP-Bang and SOS score and the association between OSAS and HAS was frequent, showing a high prevalence of hypertension in the studied population.
