ABSTRACT

Resumo Fundamento Cerca de 40% dos pacientes com infarto agudo do miocárdio com supradesnível do segmento ST (IAMCSST) no Brasil não recebem terapia de reperfusão. Objetivo A utilização de uma rede de telemedicina baseada no WhatsApp® poderia aumentar a porcentagem de pacientes que recebem terapia de reperfusão. Métodos Estudo transversal do tipo antes e depois da organização de uma rede de telemedicina para envio e análise do eletrocardiograma através do WhatsApp® dos pacientes suspeitos de IAMCSST oriundos dos 25 municípios integrantes do Departamento Regional de Saúde de Ribeirão Preto (DRS−XIII), para hospital terciário que poderia autorizar a transferência imediata do paciente utilizando o mesmo sistema. O desfechos analisados foram a porcentagem de pacientes que receberam terapia de reperfusão e a taxa de mortalidade intra-hospitalar. Considerou-se valor de p <0,05 como estatisticamente significativo. Resultados Foram comparados 82 pacientes antes desta rede (1º de fevereiro de 2016 a 31 de janeiro de 2018) com 196 pacientes depois da implantação da mesma (1º de fevereiro de 2018 a 31 de janeiro de 2020). Após a implantação da rede, houve aumento significativo da proporção de pacientes que receberam terapia de reperfusão (60% vs. 92%), risco relativo (RR): 1,594 [intervalo de confiança (IC) 95% 1,331 - 1,909], p <0,0001 e redução da mortalidade intra-hospitalar (13,4% vs. 5,6%), RR: 0,418 [IC 95% 0,189 - 0,927], p = 0,028. Conclusão Rede de telemedicina baseada no WhatsApp® associou-se a aumento da porcentagem de pacientes com IAMCSST que receberam terapia de reperfusão e a redução na mortalidade intra-hospitalar.


Abstract Background About 40% of patients with ST-segment elevation myocardial infarction (STEMI) in Brazil do not receive reperfusion therapy. Objective The use of a telemedicine network based on WhatsApp® could increase the percentage of patients receiving reperfusion therapy. Methods A cross-sectional study analyzed outcomes before and after the organization of a telemedicine network to send the electrocardiogram via WhatsApp® of patients suspected of STEMI from 25 municipalities that are members of the Regional Health Department of Ribeirão Preto (DRS−XIII) to a tertiary hospital, which could authorize immediate patient transfer using the same system. The analyzed outcomes included the percentage of patients who received reperfusion therapy and the in-hospital mortality rate. A p value < 0.05 was considered statistically significant. Results The study compared 82 patients before (February 1, 2016 to January 31, 2018) with 196 patients after this network implementation (February 1, 2018 to January 31, 2020). After implementing this network, there was a significant increase in the proportion of patients who received reperfusion therapy (60% vs. 92%), relative risk (RR): 1.594 [95% confidence interval (CI) 1.331 - 1.909], p < 0.0001 and decrease in the in-hospital mortality rate (13.4% vs. 5.6%), RR: 0.418 [95%CI 0.189 - 0.927], p = 0.028. Conclusion The use of WhatsApp®-based telemedicine has led to an increase in the percentage of patients with STEMI who received reperfusion therapy and a decrease in the in-hospital mortality rate.

ABSTRACT

Resumo Fundamento A intervenção coronária percutânea primária é considerada o "padrão-ouro" para reperfusão coronária. Entretanto, quando não disponível, a estratégia fármaco-invasiva é método alternativo, e o eletrocardiograma (ECG) tem sido utilizado para identificar sucesso na reperfusão. Objetivos Nosso estudo teve como objetivo examinar alterações no segmento-ST pós-lise e seu poder de prever a recanalização, usando os escores angiográficos TIMI e blush miocárdio (MBG) como critério de reperfusão ideal. Métodos Foram estudados 2.215 pacientes com infarto agudo do miocárdio com supra-ST submetidos à fibrinólise [(Tenecteplase)-TNK] e encaminhados para angiografia coronária em até 24 h pós-fibrinólise ou imediatamente encaminhados à terapia de resgate. O ECG foi realizado pré-TNK e 60 min-pós. Os pacientes foram categorizados em dois grupos: aqueles com reperfusão ideal (TIMI-3 e MBG-3) e aqueles com reperfusão inadequada (fluxo TIMI <3). Foi definido o critério de reperfusão do ECG pela redução do segmento ST >50%. Consideramos p-valor <0,05 para as análises, com testes bicaudais. Resultados O critério de reperfusão pelo ECG apresentou valor preditivo positivo de 56%; valor preditivo negativo de 66%; sensibilidade de 79%; e especificidade de 40%. Houve fraca correlação positiva entre a redução do segmento-ST e os dados angiográficos de reperfusão ideal (r = 0,21; p <0,001) e baixa precisão diagnóstica, com AUC de 0,60 (IC-95%; 0,57-0,62). Conclusão Em nossos resultados, a redução do segmento-ST não conseguiu identificar com precisão os pacientes com reperfusão angiográfica apropriada. Portanto, mesmo pacientes com reperfusão aparentemente bem-sucedida devem ser encaminhados à angiografia brevemente, a fim de garantir fluxo coronário macro e microvascular adequados.


Abstract Background Primary percutaneous coronary intervention is considered the "gold standard" for coronary reperfusion. However, when not available, the drug-invasive strategy is an alternative method and the electrocardiogram (ECG) has been used to identify reperfusion success. Objectives Our study aimed to assess ST-Segment changes in post-thrombolysis and their power to predict recanalization and using the angiographic scores TIMI-flow and Myocardial Blush Grade (MBG) as an ideal reperfusion criterion. Methods 2,215 patients with ST-Segment Elevation Myocardial Infarction (STEMI) undergoing fibrinolysis [(Tenecteplase)-TNK] and referred to coronary angiography within 24 h post-fibrinolysis or immediately referred to rescue therapy were studied. The ECG was performed pre- and 60 min-post-TNK. The patients were categorized into 2 groups: those with ideal reperfusion (TIMI-3 and MBG-3) and those with inadequate reperfusion (TIMI and MBG <3). The ECG reperfusion criterion was defined by the reduction of the ST-Segment >50%. A p-value <0.05 was considered for the analyses, with bicaudal tests. Results The ECG reperfusion criterion showed a positive predictive value of 56%; negative predictive value of 66%; sensitivity of 79%; and specificity of 40%. There was a weak positive correlation between ST-Segment reduction and ideal reperfusion angiographic data (r = 0.21; p <0.001) and low diagnostic accuracy, with an AUC of 0.60 (95%CI: 0.57-0.62). Conclusion The ST-Segment reduction was not able to accurately identify patients with adequate angiographic reperfusion. Therefore, even patients with apparently successful reperfusion should be referred to angiography soon, to ensure adequate macro and microvascular coronary flow.

ABSTRACT

Resumo Fundamento: A reperfusão miocárdica é parte fundamental do tratamento para infarto agudo do miocárdio com supradesnivelamento de ST (IAMCSST) e é responsável por reduzir morbimortalidade no paciente acometido. No entanto, as taxas de reperfusão são geralmente mais baixas e as taxas de mortalidade mais altas em mulheres que em homens. Objetivos: Avaliar a prevalência do uso de terapias de reperfusão em mulheres e homens com IAMCSST nos hospitais com capacidade para realizar intervenção coronariana percutânea (ICP) no estado de Sergipe. Métodos: Trata-se de estudo transversal que utilizou dados do Registro VICTIM. Foram avaliados pacientes com diagnóstico de IAMCSST admitidos nos quatro hospitais com capacidade para realizar ICP no estado de Sergipe, sendo um público e três privados, no período de dezembro de 2014 a junho de 2018. Foi aplicada análise multivariada com modelo ajustado utilizando mortalidade como variável dependente. Em todas as análises, o nível de significância adotado foi de 5% (p<0,05). Resultados: Foram incluídos 878 voluntários com diagnóstico confirmado de IAMCSST, dos quais 33,4% eram mulheres. Apenas 53,3% dos pacientes foram submetidos à reperfusão miocárdica (134 mulheres versus 334 homens). A fibrinólise foi realizada somente em 2,3% de todos os pacientes (1,7% das mulheres versus 2,6% dos homens; p=0,422). Nas mulheres, a taxa de ICP primária foi menor (44% versus 54,5%; p=0,003) e a mortalidade hospitalar foi maior (16,1% versus 6,7%; p<0,001) que nos homens. Conclusão: As mulheres apresentam taxas significativamente menores de ICP primária e significativamente maiores de mortalidade hospitalar que os homens. A taxa de reperfusão em ambos os gêneros foi baixa e houve nítida subutilização de agentes trombolíticos.


Abstract Background: Myocardial reperfusion is a fundamental part of the treatment for ST elevation myocardial infarction (STEMI) and is responsible for reducing morbidity and mortality in affected patients. However, reperfusion rates are usually lower and mortality rates higher in women compared to men. Objectives: To evaluate the prevalence of the use of reperfusion therapies among women and men with STEMI in hospitals where percutaneous coronary intervention (PCI) is available in the state of Sergipe. Methods: This is a cross-sectional study that used data from the VICTIM Register. Patients diagnosed with STEMI admitted to the four hospitals (one public and three private) where PCI is available in the state of Sergipe were evaluated, from December 2014 to June 2018. A multivariate analysis with adjusted model using mortality as a dependent variable was made. In all analyses, the level of significance adopted was 5% (p < 0.05). Results: A total of 878 volunteers with a confirmed diagnosis of STEMI, of which 33.4% were women, were included in the study. Only 53.3% of the patients underwent myocardial reperfusion (134 women versus 334 men). Fibrinolysis was performed only in 2.3% of all patients (1.7% of women versus 2.6% of men; p = 0.422). The rate of primary PCI was lower (44% versus 54.5%; p = 0.003) and hospital mortality was higher (16.1% versus 6.7%; p < 0.001) in women than in men. Conclusion: Women have significantly lower rates of primary PCI and higher hospital mortality. Reperfusion rates were low in both sexes and there was a clear underutilization of thrombolytic agents.

ABSTRACT

Resumo Objetivo: Comparar desfechos clínicos de óbito, reinfarto e Acidente Vascular Encefálico (AVE) em estudos primários que avaliaram o uso da Terapia Fibrinolítica (TF) em relação à Intervenção Coronariana Percutânea Primária (ICPP) para reperfusão miocárdica em pacientes com Infarto Agudo do Miocárdio com supradesnivelamento do segmento ST (IAMCST) no atendimento pré-hospitalar. Método: Revisão sistemática de literatura com busca realizada nas bases de dados CINAHL, MEDLINE, PUBMED, Science Direct, SCOPUS e Web of Science no período de outubro a dezembro de 2017. Foram incluídos Ensaios Clínicos Randomizados, disponíveis na íntegra, em qualquer idioma, sem recorte temporal. A avaliação da elegibilidade foi realizada em duas etapas e aplicada a Escala de Jadad para avaliação metodológica dos estudos encontrados. Resultados: Foram incluídos cinco Ensaios Clínicos Randomizados. A TF pré-hospitalar apresentou taxas de mortalidade em 30 dias após a intervenção semelhantes à ICPP, enquanto que em cinco anos foram encontrados valores menores para a TF. O tratamento instituído em um período menor que duas horas dos sintomas iniciais apresentou associação com a diminuição da mortalidade quando foi utilizada a TF. O reinfarto não-fatal, acidente vascular encefálico e a hemorragia intracraniana foram maiores quando utilizada a TF, enquanto que o choque cardiogênico apresentou menor frequência. Conclusão: A TF foi mais eficaz no tratamento pré-hospitalar para a redução dos óbitos após cinco anos, entretanto, o reinfarto e o AVE ocorreram de forma semelhante na amostra analisada. O fator tempo reduziu os desfechos clínicos, principalmente quando a terapia implementada ocorreu em até duas horas após a ocorrência do IAMCST. Assim, apesar das intervenções terem apresentado desfechos semelhantes, entretanto, a TF pode representar um tratamento viável em locais onde a ICPP não pode ser alcançada em tempo hábil.


Resumen Objetivo: Comparar resultados clínicos de fallecimiento, reinfarto y accidente vascular encefálico (AVE) en estudios primarios que analizaron el uso de la terapia fibrinolítica (TF) respecto a la intervención coronaria percutánea primaria (ICPP) para reperfusión miocárdica en pacientes con infarto agudo de miocardio con supradesnivel del segmento ST (IAMCST) en la atención prehospitalaria. Método: Revisión sistemática de literatura con búsqueda realizada en las bases de datos CINAHL, MEDLINE, PUBMED, Science Direct, SCOPUS y Web of Science en el período de octubre a diciembre de 2017. Se incluyeron ensayos clínicos aleatorizados, con texto completo disponible, en cualquier idioma, sin recorte temporal. El análisis de elegibilidad se realizó en dos etapas y se aplicó la escala de Jadad para una evaluación metodológica de los estudios encontrados. Resultados: Se incluyeron cinco ensayos clínicos aleatorizados. La TF prehospitalaria presentó índices de mortalidad 30 días después de la intervención semejantes a la ICPP, mientras que en cinco años se encontraron valores menores en la TF. El tratamiento aplicado en un período menor a dos horas desde los síntomas iniciales presentó una relación con la reducción de la mortalidad cuando se utilizó la TF. Los reinfartos no fatales, los accidentes vasculares encefálicos y las hemorragias intracerebrales fueron mayores cuando se utilizó la TF, mientras que los choques cardiogénicos presentaron menor frecuencia. Conclusión: La TF fue más eficaz en el tratamiento prehospitalario para reducir los fallecimientos después de cinco años, sin embargo, los reinfartos y los AVE ocurrieron de forma semejante en la muestra analizada. El factor tiempo redujo los resultados clínicos, principalmente cuando la terapia implementada ocurrió hasta dos horas después del episodio del IAMCST. De esta forma, a pesar de que las intervenciones presentaron resultados semejantes, la TF puede representar un tratamiento viable en lugares donde la ICPP no puede realizarse a tiempo.


Abstract Objective: To compare clinical outcomes of death, reinfarction, and stroke in primary studies assessing Fibrinolytic Therapy (FT) use in relation to Primary Percutaneous Coronary Intervention (PPCI) for myocardial reperfusion in patients with ST-Elevation Myocardial Infarction (STEMI) in prehospital care. Method: A systematic literature review conducted in the CINAHL, MEDLINE, PUBMED, Science Direct, SCOPUS, and Web of Science databases from October to December 2017. Randomized Clinical Trials, available in full, in any language, without temporal clipping were included. The eligibility assessment was carried out in two stages and applied to the Jadad Scale for methodological assessment of the studies found. Results: Five Randomized Clinical Trials were included. Prehospital FT presented mortality rates at 30 days after the intervention similar to PPCI, while in five years lower values were found for FT. The treatment instituted in a period of less than two hours of the initial symptoms was associated with the decrease in mortality when FT was used. Non-fatal reinfarction, stroke and intracranial hemorrhage were higher when FT was used, while cardiogenic shock showed lower frequency. Conclusion: FT was more effective in prehospital treatment to reduce deaths after five years, however, reinfarction and stroke occurred similarly in the sample analyzed. The time factor reduced clinical outcomes, especially when the implemented therapy occurred within two hours after the occurrence of STEMI. Thus, although the interventions presented similar outcomes. However, FT may represent a viable treatment in places where PPCI cannot be achieved in a timely manner.

ABSTRACT

Resumen Las terapias de reperfusión, tales como intervención coronaria y fibrinólisis, son las principales medidas de atención en pacientes con síndromes coronarios agudos. La angioplastia primaria se considera el estándar de oro, sin embargo, en pacientes con infección por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2), la estrategia de reperfusión más recomendada es la terapia fibrinolítica, debido al menor tiempo requerido para realizarla y menor exposición al agente infeccioso. Esta pandemia representa una problemática de contagio en el personal de salud, ya que los casos van en aumento a nivel mundial, por lo cual es importante conocer las medidas que se deben seguir a fin de evitar la enfermedad por coronavirus 2019 (COVID-19).


Abstract Reperfusion therapy is a measure of care in patients with ST-elevation myocardial infarction (STEMI), which should be performed once we have the diagnosis. Percutaneous coronary intervention is considered the gold standard, however in patients with SARS-CoV-2 infection, the reperfusion strategy is more focused on fibrinolytic therapy due to the shorter time required to perform and less exposure. This pandemic represents a contact problem in health personnel, since cases are increasing worldwide, so it is important to know the measures that must be followed to avoid coronavirus disease (COVID-19).

ABSTRACT

Introdução. O infarto agudo do miocárdio apresenta significativas taxas de morbimortalidade. A reperfusão precoce por angioplastia primária é a intervenção que reduz a mortalidade e as complicações, e deve ser iniciada em até 12 horas, a fim de impedir a perda muscular irreversível. O tempo entre chegada do paciente ao hospital e a abertura da artéria acometida, tempo porta-balão, determina a morbimortalidade do paciente. Objetivo. Esse estudo busca analisar o potencial benefício do tratamento da reperfusão coronariana precoce, os fatores de risco, as possíveis complicações e o Killip em pacientes que sofreram infarto agudo do miocárdio relacionando-os a sua morbimortalidade. Materiais e métodos. Estudo observacional transversal realizado por meio de coleta de dados dos prontuários dos pacientes submetidos a angioplastia primária de um hospital privado. Resultados. A hipertensão arterial sistêmica foi a variável mais prevalente (75%), e que houve predomínio no sexo masculino (71%) e associação com a progressão da idade. 61% dos pacientes apresentaram um tempo porta balão menor que 90 minutos. Houve significância estatística entre o tempo porta balão e a evolução do Killip, evidenciando um tempo porta-balão maior que 90 minutos na maioria dos pacientes que obtiveram aumento da pontuação do Killip. Conclusão. A precocidade da intervenção no paciente com IAM impacta na morbimortalidade, visto que o tempo porta balão está diretamente associado a evolução da do Killip. Logo, deve-se identificar os fatores que interferem no atendimento, a fim de proporcionar uma intervenção otimizada. (AU)


Introduction. Acute myocardial infarction has significant rates of morbidity and mortality. Early reperfusion by primary angioplasty is the intervention that reduces mortality and complications, and should be started within 12 hours in order to prevent irreversible muscle loss. The time between the patient's arrival at the hospital and the opening of the affected artery, door-to-balloon time, determines the patient's morbidity and mortality. Objective. The proposition of this study is to analyze the potential benefits of early coronary reperfusion, associated with the risk factors, possible complications, and the Killip score in patients whit acute myocardial infarction (AMI) and the relation of those factors with the morbidity and mortality. Materials and methods. This is a transversal observational study and uses data collected of medical records of patients subjected to primary angioplasty in a private hospital. Results. Systemic arterial hypertension was the most prevalent one (75%), it was more common in males (71%) and associated with a higher age. In 61% of the patients port-balloon time was less than 90 minutes. There was statistical significance between port-balloon time and Killip score evaluation, that showed a higher score in patient with a port-balloon time that exceeded 90 minutes. Conclusion. Early intervention in patients with AMI impacts morbimortality, once that the port-balloon time is directly associated with the Killip score results. Therefore, all factors that can lead to a delay in their care of those patients should be identified with the objective of optimize the intervention. (AU)

ABSTRACT

de Winter syndrome is a special equivalent of anterior ST-segment elevation myocardial infarction (STEMI) characterized by the absence of overt ST-elevation with upsloping ST-segment depression followed by tall symmetrical T-waves in the precordial leads, often associated with total occlusion of the proximal left anterior descending coronary artery. Herein we present a case of de Winter syndrome in a 63-year-old man, whose initial ECG showed no ST-segment elevation, but subsequent coronary angiography confirmed total occlusion of the proximal LAD coronary artery. The patient was successfully treated via mechanical reperfusion therapy and stenting through percutaneous coronary intervention (PCI). de Winter syndrome is associated with a high mortality often due to insufficient awareness of this condition by clinicians. Immediate reperfusion therapy by PCI is the life-saving treatment for the patients diagnosed with this syndrome, and prompt recognition of the ECG pattern is critical to ensure the timely administration of the therapy.

ABSTRACT

Introducción: Una serie de breves periodos de isquemias a distancia pueden limitar el daño miocárdico producido por la isquemia/reperfusión. Objetivo: Analizar las diferencias entre los dos grupos (control y estudio) teniendo en cuanta el consumo de inotrópicos y/o vasopresores durante los períodos intra y posoperatorio, así como, incidencia de eventos adversos cardiacos mayores y mortalidad en el postoperatorio. Métodos: Se realizó un estudio cuasiexperimental, explicativo, comparativo con control histórico, en dos grupos de 247 pacientes, propuestos para revascularización coronaria. Se colocó un torniquete en el brazo derecho, en el grupo estudio, alternando 3 insuflaciones con 3 desinsuflaciones con una presión de 200 mmHg, manteniéndola 5 min cada una. Este proceder se realizó previo, durante y después del evento isquémico mayor, provocado por el pinzamiento de la arteria coronaria. Resultados: Se logró una disminución significativa del consumo de drogas inotrópicas y vasoactivas. Se comprobó además, la disminución en la incidencia de bajo gasto cardiaco reversible, fibrilación ventricular, nuevo infarto agudo de miocardio. Conclusiones: El condicionamiento isquémico a distancia es una importante herramienta a tener en cuenta para la protección cardiaca perioperatoria en la revascularización coronaria(AU)


Introduction: A series of brief distant ischemia periods can limit myocardial damage produced by ischemia or reperfusion. Objective: To analyze the differences between the two groups (control and study) taking into account the consumption of inotropics and/or vasopressors during the intraoperative and postoperative periods, as well as the incidence of major cardiac adverse events and mortality in the postoperative period. Methods: A quasiexperimental, explanatory and comparative study with historical control was conducted on two groups of 247 patients proposed for coronary revascularization. A tourniquet was placed to the right arm, in the study group, alternating three insufflations with three dessufflations with a pressure of 200 mmHg, keeping each for five minutes. This procedure was performed before, during and after the major ischemic event, caused by pinching of the coronary artery. Results: A significant decrease in the consumption of inotropic and vasoactive drugs was achieved. The decrease in the incidence of low reversible cardiac output, ventricular fibrillation, and new acute myocardial infarction was also proven. Conclusions: Distant ischemic conditioning is an important tool to be taken into account for perioperative cardiac protection in coronary revascularization(AU)

ABSTRACT

Abstract Backgrund: New-onset atrial fibrillation complicating acute myocardial infarction represents an important challenge, with prognostic significance. Objective: To study the incidence, impact on therapy and mortality, and to identify predictors of development of new-onset atrial fibrillation during hospital stay for ST-segment elevation myocardial infarction. Methods: We studied all patients with ST-elevation myocardial infarction included consecutively, between 2010 and 2017, in a Portuguese national registry and compared two groups: 1 - no atrial fibrillation and 2 - new-onset atrial fibrillation. We adjusted a logistic regression model data analysis to assess the impact of new-onset atrial fibrillation on in-hospital mortality and to identify independent predictors of its development. A p value < 0.05 was considered significant. Results: We studied 6325 patients, and new-onset atrial fibrillation was found in 365 (5.8%). Reperfusion was successfully accomplished in both groups with no difference regarding type of reperfusion. In group 2, therapy with beta-blockers and angiotensin-conversion enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) was less frequent, 20.6% received anticoagulation at discharge and 16.1% were on triple therapy. New-onset atrial fibrillation was associated with more in-hospital complications and mortality. However, it was not found as an independent predictor of in-hospital mortality. We identified age, prior stroke, inferior myocardial infarction and complete atrioventricular block as independent predictors of new-onset atrial fibrillation. Conclusion: New-onset atrial fibrillation remains a frequent complication of myocardial infarction and is associated with higher rate of complications and in-hospital mortality. Age, prior stroke, inferior myocardial infarction and complete atrioventricular block were independent predictors of new onset atrial fibrillation. Only 36.7% of the patients received anticoagulation at discharge.


Resumo Fundamento: A fibrilação auricular de novo no contexto de infarto agudo do miocárdio representa um importante desafio com potencial impacto prognóstico. Objetivo: Determinar a incidência, impacto na terapêutica e mortalidade, e identificar possíveis preditores do aparecimento de fibrilação auricular de novo durante o internamento por infarto agudo do miocárdio com supradesnivelamento do segmento ST. Métodos: Estudamos todos os pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST inseridos consecutivamente de 2010 a 2017 num registro nacional português e comparamos dois grupos: 1 - sem fibrilação auricular; 2- com fibrilação auricular de novo. Efetuamos análise com modelo de regressão logística para avaliar o impacto de fibrilação auricular de novo na mortalidade intra-hospitalar e identificar preditores independentes para o seu aparecimento. Para teste de hipóteses, considerou-se significativo p < 0,05. Resultados: Estudamos 6325 pacientes, dos quais 365 (5.8%) apresentaram fibrilação auricular de novo. Não houve diferença no número de pacientes reperfundidos nem na estratégia de reperfusão. No grupo 2, terapêutica com betabloqueadores e IECA/ARA foi menos frequente, 20.6% tiveram alta sob anticoagulação oral e 16.1% sob terapêutica tripla. A fibrilação auricular de novo associou-se a maior incidência de complicações e mortalidade intra-hospitalar, mas não foi preditor independente de mortalidade intra-hospitalar. Identificamos idade, acidente vascular cerebral prévio, infarto inferior e bloqueio auriculoventricular completo como preditores independentes de fibrilação auricular de novo. Conclusões: A fibrilação auricular de novo continua sendo uma complicação frequente do infarto agudo do miocárdio, estando associada a aumento das complicações e mortalidade intra-hospitalar. Apenas 36.7% desses pacientes teve alta sob anticoagulação.

ABSTRACT

The knowledge on the management of patients with acute coronary syndrome (ACS) is essential to reduce the gap between evidence and practice. Objective: To describe a simulation training strategy for emergency healthcare professionals and provide preliminary data on knowledge acquisition, learners' confidence and prescription of medications after training. Methods: The training was part of the implementation of two myocardial infarction systems of care. It comprehended lectures and simulation-based learning using high and low-fidelity mannequins and actors. It was tested in two phases: the first one in Belo Horizonte and the second one in Montes Claros, both in the state of Minas Gerais. A test was applied before and after training to assess knowledge acquisition. Confidence to perform thrombolysis in ST-elevation myocardial infarction (STEMI) patients was assessed using a questionnaire, and the impact on medication prescription analyzed STEMI patients admitted to hospitals in Montes Claros. Results: In the first phase, 156 professionals answered both tests: 70% of them improved their results and the median number of right answers increased (6, interquartile range [IQR] 5-7; vs 7 ([IQR] 6-9; p < 0.05). In the second phase, 242 professionals answered both tests: 58% of the physicians and 83% of the nurses obtained better test scores. Participants referred a positive impact on their clinical practice, 95% reported feeling very secure when perform fibrinolysis after the training, and there was also an impact on medication prescription. Conclusions: There was an impact on the learners' knowledge acquisition and confidence using our two-phase training model, with evidence of impact on performance

ABSTRACT

Resumen En Chile, se han logrado avances importantes en el manejo del Infarto Agudo de Miocardio (IAM) con elevación del segmento ST (IAMCEST). Debido a la mejoría en el diagnóstico precoz y tratamiento, particularmente, con el incremento de la Angioplastía Primaria (APP), hoy están dadas las condiciones para seguir progresando por la vía de la combinación de estrategias de reperfusión y la creación de Redes de Manejo del IAM. El siguiente artículo revisa la evidencia que justifica impulsar dicho avance y se esbozan posibles caminos para lograrlo.


Abstract In Chile, important advances have been made in the management of Acute Myocardial Infarction (MI) with ST segment elevation (STEMI). Due to the progress in early diagnosis and treatment, particularly with the increase in Primary Angioplasty (Primary PCI), nowadays there are conditions to improve early management through the combination of reperfusion strategies and the implementation of MI reperfusion networks. The present article reviews the evidence justifying the promotion of this strategy and outlines possible actions to achieve it.

ABSTRACT

Introducción: el conocimiento sobre reperfusión coronaria en el infarto agudo del miocardio con elevación del segmento ST en el nivel primario de atención es de extraordinaria importancia para disminuir las complicaciones y la mortalidad. Objetivo: determinar las necesidades de aprendizaje de médicos de atención primaria sobre reperfusión coronaria en el infarto agudo del miocardio. Método: se realizó un estudio descriptivo de 65 galenos que laboraban en 5 policlínicos principales de urgencias de Santiago de Cuba en noviembre del 2017, para lo cual se aplicó una encuesta con variables de interés, que se calificó según metodología de evaluación y estándar previamente establecida por el equipo de trabajo. Resultados: del total de preguntas, solo una (5,9 por ciento) cumplió con el estándar de más de 70 por ciento de médicos con respuestas adecuadas; los años de experiencia y haber recibido adiestramiento influyeron positivamente en el número de dichas respuestas. La falta de capacitación fue la causa por la cual no se aplicó el tratamiento, y la planificación de esta, así como la creación de algoritmos de trabajo resultaron las medidas más propuestas por los galenos. Ninguno de ellos refirió sentirse adiestrado correctamente. Conclusiones: los médicos que laboraban en los 5 policlínicos principales de urgencias mostraron necesidades de aprendizaje y capacitación sobre el proceso de reperfusión coronaria.


Introduction: the knowledge on coronary reperfusion in the acute myocardial infarction with elevation of the ST segment in the primary care level is of extraordinary importance to decrease complications and mortality. Objective: to determine the necessities of doctors from primary care on coronary reperfusion in the acute myocardial infarction. Method: a descriptive study of 65 physicians who worked in 5 main polyclinics for emergencies of Santiago de Cuba was carried out in November, 2017 for which a survey with variables of interest was applied which was qualified according to evaluation methodology and previously established standard by the working team. Results: of all questions, only one (5.9 percent) fulfilled the standard of more than 70 percent of doctors with appropriate responses; the years of experience and receiving a previous training influenced positively in the number of these responses. The lack of training was the cause for which the treatment was not applied, and its planning, as well as the creation of working algorithms were the measures mostly proposed by the physicians. None of them referred to be correctly trained. Conclusions: doctors who worked in the 5 main emergency polyclinics showed learning necessities and training on the management for coronary reperfusion.
