Abstract

ResumoObjectivoAvaliar a prevalência da Síndrome de Apneia-Hipopneia do Sono (SAHS) em doentes internados na Unidade de Cuidados Intensivos Coronários (UCIC); determinar factores clínicos preditivos de SAHS; comparar os resultados obtidos com o estudo de sono simplificado (ESS) com os da polissonografia (PSG).MétodosEstudo prospectivo de doentes internados na UCIC com Síndrome Coronária Aguda (SCA), confirmado por coronariografia. Foram avaliados dados demográficos e antropométricos, factores de risco cardiovascular e valores da escala de sonolência de Epworth. O ESS foi realizado com ApneaLinkTM durante o internamento ou após a alta. Os doentes com índice de apneia-hipopneia (IAH) ≥ 10/h foram convidados a realizar PSG.ResultadosDurante 4 meses foram seleccionados consecutivamente 91 doentes com SCA. Cinquenta e oito doentes completaram o estudo, sendo 43 (74,1%) do sexo masculino, média etária de 61,7 ± 12,2 anos e índice de massa corporal médio de 27,4 ± 3,5 kg/m2. A mediana de tempo para realização do ESS foi de 17,5 dias. O estudo foi compatível com SAHS em 25 casos (43,1%). Aos doentes com IAH ≥ 10/h no ESS foi proposta a realização de PSG e ESS em simultâneo. A mediana do tempo entre SCA e a PSG foi de 30 dias. A PSG confirmou a positividade de todos os casos detectados pelo ESS.ConclusãoNo nosso estudo detectámos uma elevada prevalência de SAHS em doentes com SCA internados na UCIC (43,1%). Os resultados suportam a necessidade de um método de rastreio da SAHS em doentes internados com SCA. O ESS pode ter um papel importante no rastreio da SAHS nesta população.

AimTo evaluate the prevalence of Sleep Apnea-Hypopnea Syndrome (SAHS) in patients who were admitted with Acute Coronary Syndrome (ACS) to the Coronary Care Unit (CCU) and the clinical predictors of SAHS in patients with ACS and to compare the results of the simple sleep test (SST) with polysomnography (PSG).MethodsThis was a prospective study that included patients who were admitted to the CCU with ACS, which was confirmed by coronary angiography. Demographic and anthropometric data, cardiovascular risk factors and measures on the Epworth Sleepiness Scale were collected. The SST was conducted with the ApneaLinkTM device during hospitalization or after discharge. Patients with an apnea-hypopnea index (AHI) ≥ 10/h were invited to participate in PSG.ResultsNinety-one patients with ACS were consecutively included over 4 months. Of the fifty-eight patients who completed the study 43 (74.1%) were male. The mean age was 61.7±12.2 years, and the mean body mass index was 27.4±3.5 kg/m2. The median time for SST performance was 17.5 days. This study was compatible with SAHS in 25 cases (43.1%). Patients who had an AHI ≥ 10/h in the SST were submitted to PSG and SST simultaneously. The median interval between the ACS and the execution of PSG was 30 days. PSG confirmed that all of the cases that were detected by SST were positive.ConclusionIn our study, we found a high prevalence of SAHS in patients who were admitted to the CCU with ACS (43.1%). These results support the need for SAHS screening in patients who are hospitalized with ACS. The SST may have a role in the screening of SAHS in this population.
