FUNDAMENTO: A prevalência de depressão em portadores de doença arterial coronariana (DAC) é alta. A escala de depressão geriátrica (EDG) é um instrumento amplamente usado para rastrear a depressão em idosos. No Brasil, as propriedades psicométricas da versão curta ainda não foram adequadamente exploradas. OBJETIVO: Avaliar as propriedades psicométricas da versão curta da EDG em portadores de DAC em ambulatório de cardiologia. MÉTODOS: Estudo transversal que avaliou 209 idosos (≥ 65 anos) com DAC utilizando a EDG-15, Cumulative Illness Rating Scale for Geriatrics (CIRS), Brazilian OARS Multidimensional Function Assessment Questionnaire (BOMFAQ) e The Cambridge Examination for Mental Disorders of the Elderly (CAMDEX). A consistência interna da EDG-15 foi calculada pelo KR-20. Uma análise fatorial dessa escala foi conduzida. Escores da EDG-15 foram comparados com os diagnósticos de depressão (DSM-IV) para a validade de critérios. Na análise de validade concorrente, os mesmos escores foram correlacionados com os das escalas de depressão CAMDEX, Miniexame do Estado Mental (MEEM), Cambridge Cognitive Examination (CAMCOG) e BOMFAQ. RESULTADOS: A depressão clínica foi diagnosticada em 35,71% da amostra avaliada de acordo com o DSM-IV. Para o diagnóstico de depressão maior ou distimia, o ponto de corte 5/6 apresentou acurácia moderada (AUROC = 0,84), sensibilidade de 79,92% e especificidade de 78,29%. A consistência interna foi de 0,80. Na análise fatorial, três fatores obtidos explicaram 52,72% da variância total observada. Os escores da EDG-15 correlacionaram-se com os da escala de depressão CAMDEX. CONCLUSÃO: No geral, a EDG-15 apresentou boa confiabilidade e validade (concorrente e de critério). Em settings cardiológicos, seu uso pode auxiliar no rastreamento de quadros depressivos de forma simples e rápida.FUNDAMENTO: La prevalencia de depresión en portadores de enfermedad arterial coronaria (EAC) es alta.

The Geriatric Depression Scale (GDS) is a broadly used tool to screen for depression in elderly individuals. In Brazil, the psychometric properties of the short version have not been adequately assessed. OBJECTIVE: To evaluate the psychometric properties of the short version of the GDS in patients with CAD treated at a Cardiology Outpatient Clinic. METHODS: The present is a cross-sectional study that assessed 209 elderly individuals (≥ 65 years) with CAD using the GDS-15, the Cumulative Illness Rating Scale for Geriatrics (CIRS-G), the Brazilian OARS Multidimensional Function Assessment Questionnaire (BOMFAQ) and The Cambridge Examination for Mental Disorders of the Elderly (CAMDEX). The internal consistency of the GDS-15 was calculated through the KR-20. A factorial analysis of this scale was carried out. The GDS-15 scores were compared with the diagnoses of depression (DSM-IV) for the validity of criteria. At the analysis of concurrent validity, the same scores were correlated with those of the CAMDEX, mini-mental state examination (MMSE), Cambridge Cognitive Examination (CAMCOG) and BOMFAQ depression scales. RESULTS: Clinical depression was diagnosed in 35.71% of the sample assessed according to the DSM-IV. For the diagnosis of major depression or dystimia, the cutoff 5/6 presented moderate accuracy (AUROC = 0.84), sensitivity of 79.92% and specificity of 78.29%. The internal consistency was 0.80. At the factorial analysis, three obtained factors explained 52.72% of the total variance that was observed. The GDS-15 scores correlated with those of the CAMDEX depression scale. CONCLUSION: In general, the GDS-15 presented good reliability and validity (concurrent and of criterion). In cardiologic settings, its use, which is simple and fast, can be utilized in the screening for depression.

O implante de células para o tratamento de doenças cardiovasculares encontra-se sob investigação em vários centros no mundo. Várias linhagens celulares, de células-tronco bem caracterizadas a frações contendo diferentes tipos de células, têm sido investigadas em modelos animais. Apesar dos avanços obtidos na última década, na área de ciência básica, com relação a esta nova modalidade terapêutica, diversas questões permanecem sem resposta. Pouco ainda se sabe sobre os mecanismos através dos quais a terapia celular possa gerar resultados efetivos. Adicionalmente, a melhor via para o transplante, o número total e a concentração de células, e o melhor tipo celular permanecem questões importantes, ainda sem definição. É fato de que diversas células da medula óssea exercem seus efeitos através de mecanismos parácrinos e de que existe um complexo mecanismo de interação, contato e liberação de sinais entre essas células e as outras populações celulares nos órgãos lesados. Atualmente, a maioria dos estudos em humanos se concentra em células de origem adulta e autóloga, em oposição ao uso de células de origem embrionária. Esta revisão analisa os principais ensaios clínicos que utilizaram células derivadas de medula óssea em quatro cardiopatias: doença arterial coronariana aguda e crônica, e nas cardiomiopatias chagásica e dilatada. Os resultados desses estudos demonstram que o procedimento é seguro e exequível, e potencialmente eficaz. Inquestionavelmente, mais estudos pré-clínicos e clínicos são necessários para acessar o real potencial benefício desse novo modelo terapêutico.Cell transplantation for the treatment of cardiovascular diseases is being investigated in many centers throughout the world. Various cell lines, from well characterized stem cells to cell fractions containing different types of cells, have been investigated in animal models. Despite progress in the basic research of this new therapy obtained over the last decade, many questions remain unanswered. We still know very little about the mechanisms of action that may lead to positive results after cell therapy. Additionally, the best route for cell transplantation, the best number and concentration of cells and the best cell type for transplant remain important questions that are still undefined. It is a fact that many bone marrow cells exert their effects through paracrine mechanisms, and that a complex mechanism of interaction, contact and signal release exists between these cells and other cell populations in damaged organs. Currently the majority of human studies are focused on the use of adult and autologous cells in contrast to the use of embryonic cells. This review describes the main clinical trials that have been performed using bone marrow-derived cells in the setting of four distinct heart diseases: acute and chronic ischemic heart disease and chagasic and dilated cardiomyopathies. Results from these studies demonstrate the procedure to be safe and feasible, and potentially efficacious. Undoubtedly more pre-clinical and clinical studies are necessary to assess the real potential benefit of this new therapeutic model.

O ecocardiograma sob estresse com dobutamina é um método bem estabelecido para avaliar doença arterial coronária, cuja sensibilidade tem sido potencializada pela adição de atropina no final do protocolo. Indivíduos com glaucoma, doença com alta prevalência em pacientes cardiopatas com mais de 40 anos, não podem se beneficiar do uso de atropina por ser contra-indicada neste grupo. Além disso, estes indivíduos são tratados freqüentemente com betabloqueadores tópicos (colírios), que podem exercer efeitos sistêmicos diminuindo a freqüência cardíaca, pressão arterial e capacidade pulmonar. O objetivo do nosso trabalho foi verificar se a ocorrência de um possível efeito sistêmico causado por estes colírios, causando baixa resposta cronotrópica, poderia determinar resultados inconclusivos no ecocardiograma sob estresse pela dobutamina nestes pacientes com glaucoma.Dobutamine stress echocardiography is a well-established method to assess coronary artery disease, of which sensitivity has been enhanced by adding atropine at the end of the protocol. Individuals with glaucoma, a disease with a high prevalence in patients with cardiac diseases older than 40 years, cannot benefit from the use of atropine as it is contraindicated for this group of patients. Additionally, these individuals are often treated with topical betablockers (eye drops), which can have systemic effects by decreasing cardiac frequency, blood pressure and pulmonary capacity. The aim of our study was to verify whether a possible systemic effect caused by the use of these eye drops, yielding a low chronotropic response, could result in inconclusive dobutamine stress echocardiography in patients with glaucoma.

Introduction: Obstructive Sleep Apnea (OSA) is characterized by sleep fragmentation and repetitive hypoxia during sleep and has been associated with arterial hypertension, atrial fibrillation, coronary artery disease, and cardiovascular mortality. OSA has also been extensively linked with atherogenesis. Hypothesis: We sought to evaluate the role of OSA on clinical and angiographic patterns in patients admitted with acute coronary syndrome (ACS). Methods: Patients who were admitted with ACS in intensive care unit (ICU), aged over 20 years old, and with no previous diagnosis or treatment for OSA were consecutively selected between June 2013 and June 2014. A bedside overnight full polysomnography (PSG) was performed using an EMBLA digital system® within second day of admission. All patients underwent transthoracic echocardiogram. The time between pain onset and treatment (TPT) were obtained for all patients. The sample was divided into 3 groups: G1: non OSA; G2: mild to moderate OSA and G3: severe OSA according to the apnea/hypopnea index (AHI) obtained by PSG recordings. All patients signed an informed consent form. ANOVA and GLM followed by Bonferroni test were used, p Results: One hundred twenty ACS patients, 58 ± 12 y were included. Seventy-seven% underwent pharmacoinvasive strategy and 23% to primary percutaneous coronary angioplasty. Age and BMI were higher in G3 (p Conclusion: In ACS patients, severe OSA was associated with more complex coronary artery disease at hospital presentation, lower left ventricle ejection fraction., as well as in the delay of onset of treatment.

OBJETIVO: Identificar a prevalência do hábito de fumar e a ocorrência de variáveis associadas ao hábito em crianças e adolescentes de 7 a 17 anos, de ambos os sexos e provenientes da cidade de Maceió. MÉTODOS: Estudo epidemiológico transversal, baseado na população de alunos da rede de ensino público e privada, níveis fundamental e médio. Cálculo da amostra baseado na menor prevalência esperada de inúmeras variáveis, incluindo tabagismo. Amostragem por conglomerados. Questionário sobre o hábito de fumar; entrevista individual com cada estudante. Considerado fumante atual aquele que admitiu ter fumado em 1 ou mais dias nos últimos 30 dias. Variáveis analisadas: relacionadas ao estudante (idade, sexo, experimentação prévia de cigarros e trabalho remunerado), à sua condição na escola (pública/privada, turno, nível e repetência) e à família (classificação econômica, pais fumantes e pais separados). RESULTADOS: Foram avaliados 1.253 estudantes (547 do sexo masculino, média de idade 12,4±2,9 anos). Identificou-se uma prevalência de tabagismo de 2,4%. A análise estatística multivariada demonstrou associação significante do hábito de fumar com: maior idade (odds ratio de 1,31); experimentação prévia de cigarros (odds ratio de 33,96); estudar no período noturno (odds ratio de 5,43). Observou-se que 286 estudantes (22,8%) admitiram haver experimentado cigarros (9% de 7 a 9 anos; 21% de 10 a 14 anos; 36% de 15 a 17 anos). CONCLUSÕES: A prevalência de tabagismo em crianças e adolescentes da rede de ensino da cidade de Maceió é de 2,4%, sendo mais freqüente em estudantes de 15 a 17 anos, do curso noturno. Estudantes que experimentaram cigarros apresentam 34 vezes mais chances de se tornarem fumantes.OBJECTIVE: To identify the prevalence of smoking and the presence of variables associated with the habit in children and adolescents of both sexes, aged 7 to 17 years, resident in the city of Maceió. METHODS: A cross-sectional epidemiological study of the student population of the both private and public education systems at elementary and high school level. Sample size was calculated based on the minimum predicted prevalence of a large number of variables, including smoking itself. Cluster sampling was employed. A questionnaire on smoking habits was completed during individual interviews with each student. Children who admitted having smoked on 1 or more day during the previous 30 were defined as current smokers. The variables analyzed were related to: the students (age, sex, previous experimentation with cigarettes and paid employment), their educational status (public/private school, daytime/evening lessons, grade and repeated years) and their families (economic status, smoking parents and separated parents). RESULTS: A total of 1,253 students were analyzed (547 were male, mean age was 12.4 2.9 years). Observed smoking prevalence was 2.4%. Multivariate statistical analysis demonstrated significant associations between smoking and: increased age (odds ratio: 1.31); previous experimentation with cigarettes (odds ratio: 33.96); studying during the evening (odds ratio: 5.43). It was observed that 286 students (22.8%) admitted having experimented with cigarettes (9% from 7 to 9 years; 21% from 10 to 14 years; 36% from 15 to 17 years). CONCLUSIONS: The prevalence of smoking among children and adolescents in the Maceió educational system is 2.4%, being most common among students aged 15 to 17 years, studying in the evening. Students who had experimented with cigarettes exhibited a 34 times greater chance of becoming smokers.

OBJETIVO: Analisar a alteração da função pulmonar e dor em pacientes submetidos à cirurgia de revascularização do miocárdio (RM) com enxerto da artéria torácica interna esquerda (ATIE), sem circulação extracorpórea (CEC), comparando a inserção do dreno pleural nas regiões intercostal e subxifóide. MÉTODO: Vinte e oito pacientes (média de idade 57,4 ± 8,4 anos) foram alocados em dois grupos, de acordo com a posição do dreno pleural. Grupo IL (n=15) com inserção do dreno no sexto espaço intercostal esquerdo na linha axilar média; e grupo IM (n =13) inserção do dreno na região subxifóide. Todos os pacientes foram submetidos à avaliação da função pulmonar. Registros espirométricos da capacidade vital forçada (CVF) e do volume expiratório forçado no primeiro segundo (VEF1) foram obtidos no pré, primeiro, terceiro e quinto dia dias pós-operatório (PO) e a gasometria arterial em ar ambiente no pré e primeiro dia de pós-operatório. A sensação de dor foi quantificada por um escore padrão (0 a 10) no primeiro dia de pós-operatório. RESULTADOS: Em ambos os grupos houve queda significativa da CVF e do VEF1 até o quinto pós-operatório (pOBJECTIVE: To analyze the pulmonary function changes and pain in patients undergoing off-pump coronary artery bypass grafting utilizing a left internal thoracic artery graft, comparing the pleural drain insertion through the intercostal space and subxyphoid approach. METHODS: Twenty eight patients (mean age 57.4 ± 8.4 years) were divided into two groups, according to the pleural drain site. Group IL (n=15) had the pleural drain inserted through the sixth left intercostal space at the mid-axillary line and in the IM group (n=13) the drain was placed through the subxyphoid region. All the patients underwent pre- and post-operative evaluation of pulmonary function tests as well as arterial blood gas analysis. Forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were recorded in the preoperative period, and in the first, third and fifth postoperative days. The pain sensation was evaluated using a standard score from 0 to 10. RESULTS: In both groups falls in FVC and FEV1 were noted, up to the fifth postoperative day (P

Although the residual lesions after surgical correction of tetralogy of Fallot (TOF) can be evaluated by Doppler echocardiography (DE), the relation of DE parameters with the proBNP level, a potential biomarker of right ventricle overload, is not well known. The objective of this study was to evaluate the DE parameters and their relation to proBNP levels.proBNP plasma level and Doppler echocardiography parameters were obtained on the same day in 49 patients later after repair of TOF (mean age of 14.7 years, 51% female, mean PO time of 9.5 years). The DE parameters studied were the dimensions of the right atrium (RA) and ventricle (RV), RV diastolic and systolic function, and residual pulmonary lesions. The relation between them and proBNP levels were analyzed and the cutoff values of DE parameters for elevated proBNP determined.proBNP was elevated in 53% and correlated with RV diastolic diameter (r = 0.41; P = 0.003), RA longitudinal (r = 0.52; P = 0.0001) and transversal (r = 0.47; P = 0.001) diameters, pressure half time of pulmonary regurgitation (PR) velocity (PHT) (r =-0.42; P = 0.005), and the PR index (r =-0.60; P0.001). By multivariate analysis, the PR index (r =-597; P = 0,001; CI: -913.2 to -280.8) and RA longitudinal (r = 7.74; P0,001; CI 4.18 to 11.31) were independent predictors of elevated proBNP. PHT lower than 64 msec (0.76) and PRi lower than 0.65 (0.81) had the best accuracy for elevated proBNP.proBNP may be increased in patients after surgical repair of TOF, correlated with the size of right cardiac chambers and the severity of PR.
