RESUMO

Abstract Background: Takotsubo syndrome (TTS) is characterized by a temporary systolic dysfunction of the left ventricle (LV) related to a stressful event. However, the factors associated with its recurrence are still not well established. Objective: To analyze the main factors associated with TTS recurrence. Methods: A systematic review was performed using the PRISMA model. Observational studies, published between January 2008 and October 2017, which presented a recurrence rate of at least 3% and/or 5 or more patients with recurrence, and who met at least 80% of the STROBE criteria were included. Results: six articles reached the criteria to compose this systematic review. The recurrence rate ranged from 1 to 3.5% per year (global recurrence rate 3.8%). One study associated higher recurrence rate with the female gender, four reported the time between the first and second episodes, one study associated body mass index (BMI) and hypercontractility of the LV middle anterior wall to a higher recurrence rate. No association between recurrence and electrocardiographic changes were determined. Beta-blockers use was not associated with recurrence rates. Conclusions: Female gender, time from the first episode of the syndrome, low BMI and midventricular obstruction were reported as potential predictors of TTS recurrence.


Resumo Fundamento: A síndrome de Takotsubo (STT) é caracterizada por uma disfunção sistólica temporária do ventrículo esquerdo (VE) relacionada a um evento estressante. No entanto, os fatores associados à sua recorrência ainda não estão bem estabelecidos. Objetivo: Analisar os principais fatores associados à recorrência da STT. Métodos: Uma revisão sistemática foi realizada usando o modelo PRISMA. Foram incluídos estudos observacionais, publicados entre janeiro de 2008 e outubro de 2017, que apresentaram uma taxa de recorrência de pelo menos 3% e/ou 5 ou mais pacientes com recidiva e que preencheram pelo menos 80% dos critérios STROBE. Resultados: Seis artigos atenderam aos critérios para esta revisão sistemática. A taxa de recorrência variou de 1 a 3,5% ao ano (taxa de recorrência global 3,8%). Um estudo associou maior taxa de recorrência ao sexo feminino, quatro relataram o tempo entre o primeiro e o segundo episódio, um estudo associou o índice de massa corporal (IMC) e a hipercontratilidade da parede anterior média do VE a uma maior taxa de recorrência. Não foi determinada associação entre recorrência e alterações eletrocardiográficas. O uso de betabloqueadores não foi associado a taxas de recorrência. Conclusões: Sexo feminino, tempo desde o primeiro episódio da síndrome, baixo IMC e obstrução ventricular foram relatados como possíveis preditores de recorrência da STT.

RESUMO

Abstract Background: Hospital accreditation has as goal the standardization of patient care, aiming quality improvement. On 2015, a cardiology reference hospital was evaluated and got level 3 from ONA in care given to Acute Coronary Syndrome (ACS) patients. Objetive: To compare length of stay (LOS) at Coronary Care Unit (CCU) and the total LOS at the hospital of ACS patients before and after ONA 3 accreditation. Other clinical outcomes were also analyzed. Methods: Systematic and prospective registry of admitted ACS patients at CCU, whose population was divided into pre-accreditation (period 1) and post-accreditation (period 2). Descriptive analysis was performed. For statistical analysis the Mann-Whitney test, chi-squared, Fisher's exact test and Multiple Linear Regression were performed. P value was considered statistically significant when < 0,05. Results: 372 patients were admitted with ACS, 186 in period 1, of which 47 (25,3%) with ST segment Elevation Myocardial Infarction (STEMI), and 186 in period 2, of which 70 (37,6%) with STEMI. The mean age was 65,9 years (± 12,2). About the CCU LOS, there was a reduction from 3 (IQR: 2-4) to 2,5 days (IQR: 2-4; p value = 0,088). Regarding the hospital LOS, there was also a reduction from 8 (IQR: 5-12,25) to 6 days (IQR:4-11; p value = 0,004). Analyzing the type of ACS, there was a significant reduction only at the hospital LOS in non-STEMI patients: 8 to 6 days (p value = 0,001). Other hospitalization length of stay and clinical outcomes did not present a significant reduction in the comparison. Conclusion: After the ONA 3 accreditation, there was a reduction of hospital LOS. There were no significant differences in the other outcomes analyzed.

RESUMO

Abstract Background: Thrombotic disorders remain one of the leading causes of death in the Western world. Dabigatran appeared as an alternative to warfarin for anticoagulation in the treatment of atrial fibrillation (AF). The risk associated with bleeding due to its use has been documented in several randomized clinical trials, but no large study has examined in detail the risk of bleeding during dental extraction and other dental procedures involving bleeding. Objective: To compare the intensity of bleeding in individuals taking dabigatran or vitamin K antagonist (warfarin) and undergoing dental procedures. Methods: Prospective, single-center, controlled study with one single observer. Patients diagnosed with nonvalvular AF, on warfarin or dabigatran, cared for at a cardiology referral center, and requiring single or multiple dental extractions, were evaluated up to seven days post-extraction. The following outcomes were assessed: bleeding time between the beginning and the end of suture and complete hemostasis; bleeding before the procedure, after 24 hours, 48 hours, 7 days, during and after suture removal (late); p<0.05 was defined as of statistical relevance. Results: We evaluated 37 individuals, 25 in the warfarin group and 12 in the dabigatran group. Age, sex, weight, height, blood pressure, color, schooling, family income and comorbidities were similar between the two groups. Regarding bleeding after 24 hours of the procedure, no one in the dabigatran group had bleeding, whereas 32% in the warfarin group had documented bleeding (p = 0.028). The other variables analyzed did not differ between the groups. Conclusions: This study suggests that, regarding dental extraction, there is no statistically significant difference in the intensity of bleeding of patients taking dabigatran as compared to those taking warfarin. Bleeding 24 hours after the procedure was less frequent among patients on dabigatran.


Resumo Fundamento: Distúrbios trombóticos permanecem como uma das principais causas de morte no mundo ocidental. A dabigatrana surgiu como alternativa à varfarina para a anticoagulação no tratamento da fibrilação atrial (FA). O risco associado a eventos hemorrágicos com a sua utilização foi documentado em vários ensaios clínicos randomizados, mas nenhum grande estudo analisou detalhadamente o risco de hemorragia durante a extração dentária e em outros procedimentos odontológicos que envolvam sangramentos. Objetivo: Em indivíduos submetidos a procedimentos odontológicos, avaliar a intensidade de sangramento com o uso de dabigatrana em comparação ao uso de anticoagulante oral antagonista da vitamina K (varfarina). Métodos: Estudo prospectivo, controlado, unicêntrico, observador único. Pacientes com diagnóstico de FA não valvar atendidos em um centro de referência em cardiologia e com indicação de anticoagulação que necessitavam de tratamento odontológico para exodontia única ou múltipla, estando em uso de varfarina ou dabigatrana e avaliados até sete dias pós-exodontia. Foram avaliados os efeitos sobre: tempo de sangramento entre o início e o fim da sutura e hemostasia completa; sangramento antes do procedimento, após 24 e 48 horas, 7 dias, durante e após a remoção da sutura (tardio), sendo considerado como estatisticamente significativo valor de p < 0,05. Resultados: Foram avaliados 37 indivíduos, sendo 25 no grupo varfarina e 12 no dabigatrana. Idade, sexo, peso, altura, pressão arterial, cor, escolaridade, renda familiar e comorbidades foram semelhantes nos dois grupos. Em relação ao sangramento 24 horas após o procedimento, ninguém do grupo dabigatrana apresentou sangramento, que esteve presente em 32% do grupo varfarina (p = 0,028). Não houve diferenças entre os grupos em relação às outras variáveis analisadas. Conclusões: Os dados deste estudo permitem sugerir que, em indivíduos submetidos a procedimento odontológico de exodontia, não há diferença estatisticamente significante na intensidade de sangramento em uso de dabigatrana em comparação ao uso de varfarina. Há uma menor frequência de sangramento 24 horas após o procedimento nos indivíduos em uso de dabigatrana.

RESUMO

BACKGROUND: Few data exist on regional systems of care for the treatment of ST-segment-elevation myocardial infarction (STEMI) in developing countries. Our objective was to describe temporal trends in 30-day mortality and identify predictors of mortality among STEMI patients enrolled in a prospective registry in Brazil. METHODS AND RESULTS: From January 2011 to June 2013, 520 patients who received initial STEMI care at 23 nonspecialized public health units or hospitals, some of whom were transferred to a public cardiology referral center, were identified through a regional STEMI network supported by telemedicine and the local prehospital emergency medical service. We stratified patients into five 6-month periods based on presentation date. Mean age (±SD) of patients was 62.0 (±12.2) years, and 55.6% were men. The mean Global Registry of Acute Coronary Events (GRACE) score was 145 (±34). Overall mortality at 30 days was 15.0%. Use of dual antiplatelet therapy and statins increased significantly from baseline (January 2011) to period 5 (June 2013): 61.8% to 93.6% (P<0.001) and 60.4% to 79.7% (P<0.001), respectively. Rates of primary reperfusion also increased (29.1%-53.8%; P<0.001), and more patients were transferred to the referral center (44.7%-76.3%; P=0.001). Thirty-day mortality rates decreased from 19.8% to 5.1% (P<0.001). In multivariable analysis, factors independently associated with 30-day mortality were higher GRACE score, history of previous stroke, lack of transfer to the referral center, and lack of use of optimized medical therapy. CONCLUSIONS: Implementation of a regional STEMI system was associated with lower mortality and higher use of evidence-based therapies.

RESUMO

Abstract Background: There is a physiologic elevation of total cholesterol (TC) and triglycerides (TG) during pregnancy. Some authors define dyslipidemia (DLP) in pregnant women when TC, LDL and TG concentrations are above the 95th percentile (p95%) and HDL concentration is below the 5th percentile (P5%) for gestational age (GA). Objective: To compare the prevalence of DLP in pregnant women using percentiles criteria with the V Brazilian Guidelines on Dyslipidemia and the association with maternal and fetal outcomes. Results: Pregnant women with high-risk conditions, aged 18-50 years, and at least one lipid profile during pregnancy was classified as the presence of DLP by two diagnostic criteria. Clinical and laboratorial data of mothers and newborns were evaluated. Conclusion: 433 pregnant women aged 32.9 ± 6.5 years were studied. Most (54.6%) had lipid profile collected during third trimester. The prevalence of any lipid abnormalities according to the criteria of the National Guidelines was 83.8%: TC ≥ 200 mg/dL was found in 49.9%; LDL ≥ 160 mg/dL, in 14.3%, HDL ≤ 50 mg/dL in 44.4% and TG ≥ 150 mg/dL in 65.3%. Any changes of lipid according to percentiles criteria was found in 19.6%: elevation above the P95% for TC was found in 0.7%; for LDL, 1.7%; for TG 6.4% and HDL lower than the P5% in 13%. The frequency of comorbidity: hypertension, diabetes, smoking, obesity and preeclampsia was similar among pregnant women when DLP was compared by both criteria. Conclusion: The prevalence of DLP during pregnancy varies significantly depending on the criteria used, however none demonstrated superiority in association with comorbidities.


Resumo Fundamento: Durante a gestação ocorrem, fisiologicamente, elevações do colesterol total (CT) e triglicerídios (TG). Alguns autores definem dislipidemia (DLP) gestacional quando as concentrações de CT, LDL e TG são superiores ao percentil 95 (P95%) e de HDL, inferiores ao percentil 5 (P5%) para a idade gestacional. Objetivo: Comparar a prevalência da DLP em gestantes conforme critério por percentis com o da V Diretriz Brasileira de Dislipidemia e avaliar a associação com desfechos materno-fetais. Métodos: Gestantes com patologias de alto risco, idade entre 18 a 50 anos, e, pelo menos um perfil lipídico durante a gestação foram classificadas quanto à presença de DLP por dois critérios. Dados clínicos e laboratoriais das mães e neonatos foram avaliados. Resultados: Estudou-se 433 gestantes com idade de 32,9 ± 6,5 anos. A maioria (54,6%) teve o perfil lipídico coletado no terceiro trimestre. A prevalência de quaisquer das alterações lipídicas, conforme os critérios da Diretriz Nacional, foi de 83,8%: CT ≥ 200 mg/dL foi encontrado em 49,9%; LDL ≥ 160 mg/dL, em 14,3%, HDL ≤ 50 mg/dL em 44,4% e TG ≥ 150 mg/dL, em 65,3%. Quaisquer das alterações lipídicas pelo critério dos percentis foi encontrada em 19,6%: sendo que elevação superior ao P95% para CT foi encontrada em 0,7%; para LDL, em 1,7%; para TG, em 6,4% e inferiores ao P5% para o HDL em 13%. A frequência das comorbidades: hipertensão, diabetes, tabagismo, obesidade e pré-eclâmpsia foi semelhante entre as gestantes quando se comparou DLP pelos dois critérios. Conclusão: A prevalência de DLP na gestação variou significativamente conforme o critério utilizado, entretanto nenhum demonstrou superioridade na associação com comorbidades.

RESUMO

Introduction:: Emergency medicine is an area in which correct decisions often need to be made fast, thus requiring a well-prepared medical team. There is little information regarding the profile of physicians working at emergency departments in Brazil. Objective:: To describe general characteristics of training and motivation of physicians working in the emergency departments of medium and large hospitals in Salvador, Brazil. Method:: A cross-sectional study with standardized interviews applied to physicians who work in emergency units in 25 medium and large hospitals in Salvador. At least 75% of the professionals at each hospital were interviewed. One hospital refused to participate in the study. Results:: A total of 659 physicians were interviewed, with a median age of 34 years (interquartile interval: 29-44 years), 329 (49.9%) were female and 96 (14.6%) were medical residents working at off hours. The percentage of physicians who had been trained with Basic Life Support, Advanced Cardiovascular Life Support and Advanced Trauma Life Support courses was 5.2, 18.4 and 11.0%, respectively, with a greater frequency of Advanced Cardiovascular Life Support training among younger individuals (23.6% versus 13.9%; p<0.001). Thirteen percent said they were completely satisfied with the activity, while 81.3% expressed a desire to stop working in emergency units in the next 15 years, mentioning stress levels as the main reason. Conclusion:: The physicians interviewed had taken few emergency immersion courses. A low motivational level was registered in physicians who work in the emergency departments of medium and large hospitals in Salvador.

RESUMO

OBJECTIVE: To evaluate clinical and epidemiological characteristics and clinical outcomes in patients hospitalized with decompensated heart failure (DHF), with a comparison between Chagas and non-Chagas disease. METHOD: This is a retrospective cohort study involving 136 patients consecutively admitted with DHF between January 1 and December 31, 2011, with the following outcomes: acute renal failure, cardiogenic shock, rehospitalization, and hospital death. Individuals aged ≥ 18 years with DHF were included while those with more than 10% of missing data regarding outcomes were excluded. Statistical analysis was performed using SPSS version 17.0. Chi-squared test was used to compare proportions. Student's T test was used to compare means. Kaplan-Meier and log-rank tests were used to compare rehospitalization rates between the two groups over time. RESULTS: Chagasic and non-chagasic patients were compared. The first had lower mean systolic blood pressure (111.8±18.4 versus 128.8±24.4, p<0.01), lower mean diastolic blood pressure (74.5±13.6 versus 82.0±15.2, p<0.01) and lower left ventricular ejection fraction (26.5±6.2 versus 41.5±18.9, p<0.01). In all, 20 patients with Chagas (50.1%) were rehospitalized, compared to 35 patients in the non-Chagas group (35.4%, p=0.04). Log rank test = 4.5 (p<0.01) showed that rehospitalization rates between the two groups over time (Kaplan-Meier curves) differed. CONCLUSION: Chagas disease was associated with lower systolic and diastolic blood pressure and lower left ventricular ejection fraction. The rehospitalization rate was higher in Chagas disease.

Resumo Objetivo: Avaliar características clínico-epidemiológicas e desfechos clínicos em pacientes internados por insuficiência cardíaca descompensada (ICD), estabelecendo uma comparação entre pacientes chagásicos e não chagásicos. Método: Trata-se de um estudo de coorte retrospectivo abrangendo 136 pacientes internados consecutivamente com ICD entre 1 de janeiro e 31 de dezembro de 2011, tendo como desfechos: lesão renal aguda, choque cardiogênico, reinternamento e óbito hospitalar. Foram incluídos indivíduos com idade ≥ 18 anos com ICD e excluídos aqueles com mais de 10% de dados faltantes em relação aos desfechos. Para a análise estatística, foi utilizado o SPSS® versão 17.0. Para a comparação entre proporções, foi utilizado o teste Qui-quadrado. O teste T de Student foi utilizado para comparar médias. Utilizamos as curvas de Kaplan-Meier e o teste do log rank para comparar as taxas de reinternações entre os dois grupos ao longo do tempo. Resultados: Na comparação entre chagásicos e não chagásicos, os primeiros apresentaram menor média de pressão arterial sistêmica (111,8±18,4 versus 128,8±24,4; p<0,01), menor média de pressão arterial diastólica (74,5±13,6 versus 82,0±15,2; p<0,01) e menor fração de ejeção do ventrículo esquerdo (26,5±6,2 versus 41,5±18,9; p<0,01). Um total de 20 chagásicos (50,1%) reinternaram contra 35 não chagásicos (35,4%; p=0,04). O teste do log rank = 4,5 (p<0,01) mostrou que as taxas de reinternações entre os dois grupos ao longo do tempo (curvas de Kaplan-Meier) diferiram. Conclusão: A doença de Chagas associou-se a menores valores de pressão arterial sistólica e diastólica, além de menor fração de ejeção do ventrículo esquerdo.

RESUMO

OBJECTIVE: To evaluate the agreement between the three scores proposed by the II Guideline for Perioperative Evaluation of the Brazilian Society of Cardiology (SBC): the American College of Physicians algorithm (ACP), the Multicenter Study of Perioperative Evaluation (EMAPO) and Lee's Revised Cardiac Risk Index (RCRI). METHOD: Patients evaluated preoperatively for non-cardiac surgery by the anesthesiology service were classified as low, moderate or high-risk according to the 3 algorithms suggested by the II Guideline. To calculate the strength of agreement between the scores, the kappa agreement index was used. RESULTS: Four hundred and one patients were included in the sample. Cohen's kappa inter-rater agreement between scores was 0.270 (CI: 0.222 to 0.318), corresponding to a weak agreement. Analyzing in pairs, the best correlation was between EMAPO and ACP, with kappa = 0.327. Lee's score was the one that classified more patients as low-risk: 98.3%, while EMAPO and ACP classified as low risk 91.3% and 92.5%, respectively. CONCLUSION: There is poor correlation among the risk scores proposed by the II Perioperative Evaluation Guideline of the SBC.

RESUMO Objetivo: avaliar a concordância entre os três escores propostos pela II Diretriz de Avaliação Perioperatória da Sociedade Brasileira de Cardiologia (SBC): algoritmo do American College of Physicians (ACP), Estudo Multicêntrico de Avaliação Perioperatória (Emapo) e Índice de Risco Cardíaco Revisado de Lee (IRCR). Método: pacientes avaliados no pré-operatório para cirurgia não cardíaca em serviço de anestesiologia foram classificados em baixo, moderado ou alto risco pelas três escalas sugeridas pela II Diretriz. Para avaliar o grau de concordância entre as classificações, calculou-se o índice de concordância kappa. Resultados: quatrocentos e um pacientes foram incluídos. O índice kappa de Cohen de concordância entre os três escores foi de 0,270 (IC: 0,222-0,318), correspondendo a uma concordância fraca. Analisando aos pares, a melhor correlação foi entre Emapo e ACP, com kappa de 0,327. O escore de Lee foi o que classificou mais pacientes como baixo risco: 98,3%, ao passo que Emapo e ACP classificaram como baixo risco 91,3 e 92,5%, respectivamente. Conclusão: há uma baixa concordância entre os escores de risco propostos pela II Diretriz de Avaliação Perioperatória da SBC.

RESUMO

OBJETIVO: Descrever o estilo de vida de pacientes admitidos em uma unidade coronariana com diagnóstico de infarto agudo do miocárdio. MÉTODOS: Estudo de corte transversal, observacional, realizado entre março e junho de 2012, em um hospital da cidade de Juazeiro (BA). O questionário utilizado foi o FANTASTIC, que é uma ferramenta validada internacionalmente, inclusive no Brasil. O questionário foi aplicado aos pacientes durante os primeiros dias de internação na unidade fechada, e os dados secundários foram coletados nos prontuários. RESULTADOS: Responderam ao questionário 57 pacientes, sendo 63,2% do sexo masculino, com idade média 61,3±10,9 anos e índice de massa corporal médio de 27,0±4,4kg/m2. A média de pontuação pelo questionário foi de 57,2±7,2, e 63,2% apresentaram um "bom" estilo de vida pela classificação previamente padronizada. As mulheres apresentaram um escore de estilo de vida melhor do que os homens (61,1±5,1 pontos versus 55,0±7,3 pontos; p=0,001). Houve menor pontuação nos domínios nutrição, atividade física e tabagismo. CONCLUSÃO: Os pacientes com infarto agudo do miocárdio apresentaram um escore "bom" pelo questionário FANTASTIC. Alguns domínios, no entanto, mostram valores baixos, como atividade física, nutrição e tabagismo.


OBJECTIVE: To describe the lifestyle of patients admitted to a coronary care unit with acute myocardial infarction. METHODS: Observational cohort study, conducted between March and June, 2012, in a hospital of Juazeiro (BA), Brazil. The questionnaire used was FANTASTIC, that is an internationally validated tool, including Brazil. This was administered to patients during the first days in the coronary care unit and the secondary data were collected from the medical records. RESULTS: Fifty-seven patients answered the questionnaire, 63.2% male, mean age 61.3±10.9 years and mean body mass index of 27.0±4.4kg/m2 . Mean score of the questionnaire was 57.2±7.2; and 63.2% had a "good" lifestyle by previously standardized classification. Women had a better lifestyle score than men (61.1±5.1 points versus 55.0±7.3 points; p=0.001) There were lower scores in the areas nutrition, physical activity and smoking questionnaire. CONCLUSION: Acute myocardial infarction patients had a "good" score in the FANTASTIC questionnaire. Some domains, however, were undesirably low: physical activity, nutrition and smoking.
