Background: Acute Coronary Syndrome (ACS), whose main pathological substrate is atherosclerosis, is one of the main causes of morbidity and mortality in the modern world. Disorders related to sleep quality (DRS), which are highly prevalent in adults, are considered independent risk factors for cardiovascular disease (CVD). Objectives: to investigate the influence of sleep quality on the prognosis of patients with ACS. Method: This is an observational and cohort study, which included 254 consecutive patients with a diagnosis of ACS admitted at a cardiology hospital, from July 2014 to October 2016. All volunteers answered to the Pittsburgh Sleep Quality Index (PSQI), the Berlin Questionnaire (BQ), the Epworth Sleepiness Scale (ESS), Medical Outcomes Study 36-item Short Form (SF-36), and were followed for cardiovascular events (CVE) during hospitalization, based on a standardized evaluation, administered by the researcher, associated to medical records. Results: Patients were hospitalized with Unstable Angina (43.31%), AMI without SST (37.01%) and AMI with SST (19.69%). Only 88 (34.65%) presented good sleep quality and 166 (65.35%) patients presented poor sleep quality. The occurence of intra-hospital outcome was associated to AMI with SST diagnosis (OR=5.13; CI: 95% 2.14 – 12.79; p=0.0003) and systemic arterial hypertension (SAH) (OR=3.26; CI: 95% 1.26 – 9.71; p=0.0215). Conclusion: It was not possible to demonstrate the existence of association between poor sleep quality and worse intra-hospital evolution of ACS patients. It was verified a higher probability to the occurrence of intra-hospital outcome in AMI with SST and hypertensive patients.
