As doenças cardiovasculares, quando agravadas, podem requerer cuidados hospitalares específicos em Centro de Tratamento Intensivo (CTI). As características desta unidade podem potencializar o afastamento do paciente de sua subjetividade, aumentando a vulnerabilidade para desenvolvimento de delirium – uma das síndromes mais comuns no ambiente hospitalar, especialmente na população idosa. Frente a isso, foram avaliados 94 pacientes com idade igual ou superior a 60 anos, a fim de identificar se existe relação entre a ansiedade e depressão no momento da internação em CTI de um hospital cardiológico e o desenvolvimento de delirium nas 48 horas seguintes. Foram utilizadas a Escala Hospitalar de Ansiedade e Depressão (HADS) e a Confusional Assessment Method in Intensive Care Unit (CAM-ICU). Foi possível observar uma tendência de que pacientes com sintomas de ansiedade e, principalmente, de depressão têm maior probabilidade de desenvolver delirium. Entre os pacientes com depressão, 18.8% apresentaram delirium e, daqueles sem depressão, 4.2%. Em relação à ansiedade, 11.1% dos que apresentaram ansiedade tiveram também delirium, comparado a 4.1% entre aqueles sem ansiedade. Observa-se a importância de se identificar o impacto de sintomas psicológicos na evolução clínica do paciente, tendo em vista a associação de delirium a desfechos clínicos desfavoráveis.

"Introduction: Acute myocardial infarction is an experience that may cause severe emotional impact to the individual who presented it. The anxiety and depression felt is caused not only by the infarction episode itself, but also by the current uncertain state of the world during and because of the COVID-19 pandemic, something which can heighten these negative feelings throughout the entire population, especially in those considered to be in high risk groups. Objective: The objective of the present study is to estimate the prevalence of anxiety and depression among patients infarcted during the current coronavirus pandemic in the state of Rio Grande do Sul. This study will compare clinical characteristics and risk factors between groups with and without anxiety and depression. Methods: Acute myocardial infarction patients who were submitted to percutaneous coronary intervention from February to June 2020 at a reference hospital in cardiology were considered eligible. The patients were interviewed via phone calls. The clinical characteristics and intra-hospital events were obtained from the hospital’s REDCap Database. The level of anxiety and depression suffered was evaluated utilizing the HADS (Hospital Anxiety and Depression Scale). Patients considered as suffering from anxiety and depression were those who obtained scores for the possible and probable presence of those mood disorders. Patients were divided into groups with and without anxiety and depression. The categorical variables were expressed through frequency and percentage and analyzed by the Chi-square test and the continuous variables were described by average and standard deviation, and analyzed by Student's t-test. Results: A total of 55 patients were interviewed. The majority of these patients were male (74,5%) and white (80%). The average age of those participating in the study was 58 ±12 years, and the female participants were older than the males. The average number of years of education was 8 ± 4 years. The prevalence of anxiety was 38,2% and of depression 30,9%. Conclusions: The prevalence of anxiety and depression was higher than those described in the literature for this population, which supports the hypothesis that the pandemic may be aggravating the patient’s emotional state. Another group will be interviewed for the control group."
