Inclusion Criteria

The sample will be composed of patients older than 18 years; who suffered a primary event of acute myocardial infarction with or without supra-level ST tracking; hospitalized to an intensive care unit; with a minimum score of 14 points in the Glasgow Coma Scale; with a stay of at least 12 hours in the unit, without cognitive impairment; in spontaneous ventilation or using noninvasive ventilatory support

Exclusion Criteria

Blind patients of the quiasmatic type will be excluded. Also excluded are patients who are in Killip IV; sedata; inpatient women without the use of delayed bladder catheterization; inincontinent men without the use of delayed bladder catheterization and who do not adapt to the use of a non-invasive device for urine collection (Uripen®); patients who have predictors related to sleep apnea such as: Body Mass Index (BMI) greater than 35; Score greater than 10 on the Epworth daytime sleepiness rating scale; Snoring; witnessed apneas; wheezing that suffocates the night; unfavorable clinical outcome (hemodynamic and respiratory instability); confirmed diagnosis of sleep apnea and patients who were discharged during data collection

Study & Design

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
To verify the improvement of sleep quality parameters through analysis of the variables related to sleep (Activity and rest evaluation by actigraphy; Questionnaire for assessing the quality of sleep in the cardiological ICU; Chronotype Questionnaire Morningness- Eveningness Questionnaire (MEQ) by Horne & Östberg). The data will be analyzed using: mean, median, standard deviation, paired T-Test and analysis of variance (ANOVA),Considering significant p values less than or equal to 0.05.;To verify the improvement of pain reports by pain score through the numerical verbal pain scale (0-10).

Secondary Outcome Measures

Name	Time	Method
Evaluation of the perception of daytime sleepiness after the use of glasses with blue light block in the night period,Through the Epworth scale and evaluation of sleep quality in the last month through the Pittsburgh Sleep Quality Index Questionnaire PSQI). The data will be analyzed using: mean, median, standard deviation, paired T-Test and analysis of variance (ANOVA),Considering significant p values less than or equal to 0.05.;Evaluate the excretion level of the urinary melatonin metabolite. Laboratory analysis of the level of 6-sulfatoximelatonin in the urine will be performed using the ELISA method, from the evaluation by the Spectrophotometer.The quantification of the samples will be performed by interpolating the values in a standard curve.The data will be analyzed using: mean, median, standard deviation, paired T-Test and analysis of variance (ANOVA),Considering significant p values less than or equal to 0.05.
