Objective to investigate the associations of preoperative anxiety and depression
symptoms with postoperative complications and with sociodemographic and
clinical characteristics of patients submitted to the first coronary artery
bypass graft.Method observational, analytical and longitudinal study. A consecutive
non-probabilistic sample consisted of patients submitted to coronary artery
bypass graft. To evaluate the symptoms, the Hospital Anxiety and Depression
Scale was used. tracheal intubation for more than 48 hours, hemodynamic
instability, sensorineural deficit, agitation, hyperglycemia, infection,
nausea, vomiting, pain and death were classified as complications. The
Mann-Whitney and Spearman Correlation tests were used, with a significance
level of 0.05.Results a total of 75 patients participated. The group that presented hemodynamic
instability in the postoperative period had a greater median for the anxiety
symptoms (p = 0.012), as well as the women (p = 0.028). The median of the
depression symptoms was higher in the group presenting nausea (p = 0.002),
agitation (p <0.001), tracheal intubation for more than 48 hours (p =
0.018) and sensorineural deficit (p = 0.016).Conclusion there was association of the symptoms of preoperative anxiety with
hemodynamic instability in the postoperative period and with the female
gender, as well as association of depression symptoms with the following
complications: nausea, agitation, time of intubation in the postoperative
period and sensorineural deficit.
