RESUMO
OBJETIVO: Demonstrar a prevalência da hiperglicemia de estresse em coorte de pacientes com síndrome coronariana aguda e a correlação com óbito, insuficiência cardíaca e/ou disfunção ventricular esquerda sistólica, na fase intra-hospitalar. MÉTODOS: Estudo de coorte prospectiva inicial constituída por pacientes internados com síndrome coronariana aguda, com ou sem supradesnivelamento do segmento ST. Foram comparados os grupos para demonstrar a correlação entre hiperglicemia de estresse e eventos cardiovasculares. Na comparação entre os grupos com e sem hiperglicemia de estresse, foram usados o teste do qui-quadrado ou exato de Fisher, e o teste t de student. As variáveis com valor de p<0,20 na análise univariada foram submetidas à regressão logística variáveis. RESULTADOS: Foram estudados 363 pacientes com média etária de 62,06±12,45 anos, com predomínio do gênero masculino (64,2%). O total de 96 pacientes (26,4%) apresentou hiperglicemia de estresse. Não houve diferenças entre os grupos com ou sem hiperglicemia de estresse. A área sobre a curva ROC foi de 0,67 para relação entre a hiperglicemia de estresse e o desfecho composto insuficiência cardíaca, disfunção sistólica de ventrículo esquerdo ou óbito ao fim da internação. A curva ROC mostrou ser a hiperglicemia de estresse fator preditivo do desfecho composto (óbito, insuficiência cardíaca e/ou disfunção ventricular). A análise multivariada não apontou fator de risco a idade, hiperglicemia de estresse ou frequência cardíaca de admissão. CONCLUSÃO: A hiperglicemia de estresse na amostra estudada foi frequente. Sua presença associou-se, na análise univariada, com eventos como óbito, insuficiência cardíaca e/ou disfunção ventricular na fase intra-hospitalar, em pacientes com síndrome coronariana aguda.
OBJECTIVE: To demonstrate the prevalence of stress hyperglycemia in a cohort of patients with acute coronary syndrome and to determine the correlation of stress hyperglycemia with death, heart failure and/or left ventricular systolic dysfunction during the intrahospital phase. METHODS: A prospective initial cohort study of hospitalized patients with acute coronary syndrome with or without ST segment elevation. The groups were compared to demonstrate the correlation between stress hyperglycemia and cardiovascular events. The chi-square test or Fisher's exact test and student's t-test were used to compare the groups with and without stress hyperglycemia. The variables with p<0.20 in the univariate analysis were submitted to logistic regression. RESULTS: In total, 363 patients with an average age of 12.45 ± 62.06 were studied. There was a predominance of males (64.2%). In total, 96 patients (26.4%) presented with stress hyperglycemia. There were no differences between the groups with or without stress hyperglycemia. The area under the ROC curve was 0.67 for the relationship between stress hyperglycemia and the composite outcome heart failure, left ventricular systolic dysfunction or death at the end of the hospital admission. The ROC curve proved that stress hyperglycemia was the predictor of the composite outcome (death, heart failure and/or ventricular dysfunction). The multivariate analysis did not indicate age, stress hyperglycemia or admission heart rate as risk factors. CONCLUSION: Stress hyperglycemia was common in the studied sample. In the univariate analysis, the presence of stress hyperglycemia was associated with such events as death, heart failure and/or intrahospital ventricular dysfunction in patients with acute coronary syndrome.

RESUMO
BACKGROUND: Our study set out to determine the prevalence of depressive symptoms and variables that influence its presence in patients hospitalized for heart failure. Depression is associated with a substantially increased risk of developing heart failure in individuals at risk, and has been related to adverse outcomes in patients with established heart failure. It is important to determine its prevalence in different populations and assess related causes. METHODS: We conducted a cross-sectional study of 103 patients with heart failure, admitted to public hospital, via a questionnaire that evaluates clinical variables, socio-demographics and we applied the Beck Depression Inventory to determine the prevalence of depressive symptoms and predictors of their presence. We used the chi2, Student test and considered significant when < 0.05 and subjected to logistic regression analysis when between 0.05 and 0.1. RESULTS: The mean age of the patients in our study was 65.4 ± 13.6. Depressive symptoms were present in 69 (67%) patients: 35 (34%) had mild depressive symptoms, 22 (21.3%) had moderate symptoms and 12 (11.6%) patients presented severe symptoms. Marital status was significant when analyzed, and the predictors of depressive symptoms were marital status, sex, living arrangements and heart failure etiology. CONCLUSIONS: Because depressive symptoms in patients hospitalized for heart failure are very common, it is important to detect these disorders. The prevalence of these varies according to socio-demographic and clinical data, and these factors should be taken into consideration when planning future studies, as well as screening and intervention programs for co-morbid depressive disorders in hospitalized patients with heart failure.

Fundamentos. Estudos sobre sintomas depressivos (SD) têm sido feitos em pacientes hospitalizados por insuficiência cardíaca (IC) e tem sido ignorada a influência de várias características. Objetivos. Avaliar prevalência, preditores e correlação da gravidade dos SD e a mortalidade em hospitalizações por IC. Métodos. Estudo prospectivo que analisou hospitalizações consecutivas por IC. Foram analisados dados sociodemográficos, clínicos e o desfecho considerado foi óbito. Na análise dos SD foi utilizado o Inventário de Depressão de Beck. Foi feita análise comparativa entre grupos com e sem SD e submetidos a regressão logística as variáveis com p entre 0,05 e 0,1. Avaliou-se a relação entre a gravidade de SD e mortalidade. Foi utilizado teste qui-quadrado ou exato de Fisher para variáveis categóricas e t de student para contínuas. Foi considerado estatisticamente significante p<0,05. Resultados. Foram avaliados 103 pacientes, sendo 63,1% mulheres, 50,5% casados e alfabetizados 73,8%. O total de 75,2% estava em classe funcional II e III de New York Heart Association (NYHA). Hipertensão arterial sistêmica foi a comorbidade mais comum (92,2%). A presença de SD foi presente em 69 (67%) pacientes. Os preditores de SD foram: estado civil (p=0,03) e na regressão logística: sexo (p<0,0001), modo de vida (0,002) e etiologia da IC (p<0,0001). A mortalidade relacionou-se à SD em sintomas moderados (p=0,04) e graves (0,01). Conclusão. Os SD são comuns em hospitalizações por IC. A prevalência varia conforme características clínicas dos pacientes. Os preditores foram sexo, estado civil, modo de vida e etiologia da IC. A mortalidade relacionouse a SD moderados e graves.
Background. Studies of depressive symptoms (DS) has been made in patients hospitalized for heart failure (HF) and the influence of various characteristics has been ignored. Objectives. To assess prevalence, predictors and correlated to the severity of DS and mortality in HF hospitalizations. Methods. This prospective study examined consecutive hospitalizations for HF. We analyzed sociodemographic data and clinical outcome was death. In analysis of DS was used Beck Depression Inventory II. Comparative analysis were made between groups with and without DS and subjected to logistic regression variables with p between 0.05 and 0.1. We evaluated the relationship between the severity of SD and mortality. It was considered statistically significant p <0.05. Results: We evaluated 103 patients, 63.1% women, 50.5% were married and 73.8% literate. A total of 75.2% were in New York Heart Association (NYHA) functional class II and III. Hypertension was the most common comorbidity (92.2%). The DS was present in 69 (67%) patients. The predictors of DS were: marital status (p=0.03) and logistic regression: sex (p<0.0001), lifestyle (0.002) and etiology of HF (p<0.0001). Mortality was related to the DS in moderate symptoms (p=0.04) and severe (0.01). Conclusion. The DS are common in HF hospitalizations. The prevalence varies according to clinical characteristics of patients. The predictors were gender, marital status, lifestyle and etiology of HF. Mortality was related to moderate and severe DS.
