A importância do controle pressórico e alcance de metas pressóricas intensivas em pacientes diabéticos e em pacientes com acidente vascular cerebral: os estudos optimal-diabetes e optimal-stroke / The importance of blood pressure control and intensive blood pressure targets in patients with diabetes and stroke: the optimaldiabetes and optimal-stroke trials

A hipertensão arterial sistêmica representa um dos principais problemas de saúde pública no Brasil e no mundo. O controle pressórico estrito é essencial para a redução de eventos cardiovasculares maiores, pois a pressão arterial sistólica elevada é o principal fator de risco modificável para doenças cardiovasculares e mortalidade total. Ensaios clínicos randomizados prévios, como o SPRINT trial e o STEP trial, geraram evidências robustas sobre os benefícios do alcance de metas pressóricas intensivas na redução de eventos cardiovasculares maiores em pacientes hipertensos de alto risco cardiovascular não-diabéticos e sem acidente vascular cerebral (AVC) prévio. Porém, ainda há dúvidas sobre o benefício de tal estratégia nestas duas populações de pacientes. Para dar uma resposta definitiva a esta questão, os estudos OPTIMAL-DIABETES e OPTIMAL-STROKE estão sendo conduzidos com alto rigor científico no Brasil e estes já são os maiores estudos sobre o tema em nível global. Os resultados destes dois estudos, previstos para 2024/2025, são muito esperados para nos dar as evidências necessárias sobre o benefício do controle pressórico intensivo em pacientes diabéticos e pós-AVC (AU).

Hypertension represents one of the main public health problems in Brazil and in the world. Blood pressure (BP) control is essential to reduce major cardiovascular events, as high systolic BP is the main modifiable risk factor for cardiovascular diseases and any-cause deaths. Previous randomized clinical trials, such as the SPRINT trial and the STEP trial, have provided robust evidence on the benefits of intensive BP targets on the reduction of major cardiovascular events in hypertensive patients with high cardiovascular risk without diabetes and previous stroke. However, there is still uncertainty about the benefits of such strategy on this two populations of patients. To provide a definitive answer to this question, the OPTIMAL-DIABETES and OPTIMAL-STROKE trials are being conducted with high scientific rigor in Brazil and these are already the biggest studies in this area globally. The results of these two trials, expected in 2024/2025, are long awaited to provide us the necessary evidence on the benefits of intensive BP control in patients with diabetes and patients with stroke (AU).

Metformin use and risk of ischemic stroke in patients with type 2 diabetes: A cohort study / 北京大学学报(医学版)

OBJECTIVE@#To explore the association between the use of metformin and the risk of ischemic stroke in patients with type 2 diabetes.@*METHODS@#A prospective cohort study was designed from the Fangshan family cohort in Beijing. According to metformin use at baseline, 2 625 patients with type 2 diabetes in Fangshan, Beijing were divided into metformin group or non-metformin group and the incidence of ischemic stroke between the different groups during follow-up was estimated and compared by Cox proportional hazard regression model. The participants with metformin were first compared with all the parti-cipants who did not use metformin, and then were further compared with those who did not use hypoglycemic agents and those who used other hypoglycemic agents.@*RESULTS@#The patients with type 2 diabetes were with an average age of (59.5±8.7) years, and 41.9% of them were male. The median follow-up time was 4.5 years. A total of 84 patients developed ischemic stroke during follow-up, with a crude incidence of 6.4 (95%CI: 5.0-7.7) per 1 000 person-years. Among all the participants, 1 149 (43.8%) took metformin, 1 476 (56.2%) were metformin non-users, including 593 (22.6%) used other hypoglycemic agents, and 883 (33.6%) did not use any hypoglycemic agents. Compared with metformin non-users, the Hazard ratio (HR) for ischemic stroke in metformin users was 0.58 (95%CI: 0.36-0.93; P = 0.024). Compared with other hypoglycemic agents, HR was 0.48 (95%CI: 0.28-0.84; P < 0.01); Compared with the group without hypoglycemic agents, HR was 0.65 (95%CI: 0.37-1.13; P=0.13). The association between metformin and ischemic stroke was statistically significant in the patients ≥ 60 years old compared with all the metformin non-users and those who used other hypoglycemic agents (HR: 0.48, 95%CI: 0.25-0.92; P < 0.05). Metformin use was associated with a lower incidence of ischemic stroke in the patients with good glycemic control (0.32, 95%CI: 0.13-0.77; P < 0.05). In the patients with poor glycemic control, and the association was not statistically significant (HR: 0.97, 95%CI: 0.53-1.79; P>0.05). There was an interaction between glycemic control and metformin use on incidence of ischemic stroke (Pinteraction < 0.05). The results of the sensitivity analysis were consistent with the results in the main analysis.@*CONCLUSION@#Among patients with type 2 diabetic in rural areas of northern China, metformin use was associated with lower incidence of ischemic stroke, especially in patients older than 60 years. There was an interaction between glycemic control and metformin use in the incidence of ischemic stroke.

Estratégias Econômicas e Sociais para Anticoagulação de Pacientes com Fibrilação Atrial / Economy- and Social-Based Strategies for Anticoagulation of Patients with Atrial Fibrillation

Resumo Fundamento: A fibrilação atrial é um problema de saúde pública associado com um risco cinco vezes maior de acidente vascular cerebral e mortalidade. A análise de custos é importante para a introdução de novas terapias, e deve ser reconsiderada em situações especiais, tais como a pandemia do coronavírus em 2020. Objetivo: Avaliar os custos (em um período de um ano) relacionados à terapia anticoagulante e a qualidade de vida de pacientes com fibrilação atrial tratados em um hospital público universitário. Métodos: Os custos do paciente foram aqueles relacionados à anticoagulação e calculados pela média de custos mensais da varfarina ou de anticoagulantes orais diretos (DOACs). As despesas não médicas, como alimentação e transporte, foram calculadas a partir de dados obtidos de questionários. O questionário brasileiro SF-6D foi usado para medir a qualidade de vida. Valores p<0,05 foram considerados estatisticamente significativos. Resultados: A população do estudo consistiu em 90 pacientes, 45 em cada braço (varfarina vs. DOACs). Os custos foram 20% mais altos no grupo dos DOACs (US$55 532,62 vs. US$46 385,88), e principalmente relacionados ao preço dos medicamentos (US$23 497,16 vs. US$1903,27). Os custos hospitalares foram mais altos no grupo da varfarina (US$31 088,41 vs $24 604,74), e relacionados às visitas ao ambulatório. Ainda, as despesas não médicas foram duas vezes maiores no grupo varfarina ($13 394,20 vs $7 430,72). A equivalência de preço entre os dois medicamentos seria alcançada por uma redução de 39% no preço dos DOACs. Não foram observadas diferenças quanto à qualidade de vida. Conclusões: Os custos totais foram mais altos no grupo de pacientes tratados com DOACs que no grupo da varfarina. No entanto, uma redução de cerca de 40% no preço dos DOACs tornaria viável a incorporação desses medicamentos no sistema de saúde público brasileiro.

Abstract Background: Atrial fibrillation is a public health problem associated with a fivefold increased risk of stroke or death. Analyzing costs is important when introducing new therapies and must be reconsidered in special situations, such as the novel coronavirus pandemic of 2020. Objective: This study aimed to evaluate the costs related to anticoagulant therapy in a one-year period, and the quality of life of atrial fibrillation patients treated in a public university hospital. Methods: Patient costs were those related to the anticoagulation and calculated by the average monthly costs of warfarin or direct oral anticoagulants (DOACs). Patient non-medical costs (eg., food and transportation) were calculated from data obtained by questionnaires. The Brazilian SF-6D was used to measure the quality of life. P-values < 0.05 were considered statistically significant. Results: The study population consisted of 90 patients, 45 in each arm (warfarin vs direct oral anticoagulants). Costs were 20% higher in the DOAC group ($55,532.62 vs $46,385.88), and mainly related to drug price ($23,497.16 vs $1,903.27). Hospital costs were higher in the warfarin group ($31,088.41 vs $24,604.74) and related to outpatient visits. Additionally, non-medical costs were almost twice higher in the warfarin group ($13,394.20 vs $7,430.72). Equivalence of price between the two drugs could be achieved by a 39% reduction in the price of DOACs. There were no significant group differences regarding quality of life. Conclusions: Total costs were higher in the group of patients taking DOACs than those taking warfarin. However, a nearly 40% reduction in the price of DOACs could make it feasible to incorporate these drugs into the Brazilian public health system.

The construction of comprehensive stroke prevention and control system requires attention to the precise policies of young stroke / 中华预防医学杂志

Youth is the core force of social and economic development, once the occurrence of youth stroke will place a heavy burden on society and family. However, the prevention and control of stroke in China is mainly aimed at middle-aged and elderly patients, the part of young stroke is relatively easy to be ignored. This article focuses on the characteristics, research progress, prevention and control status of young stroke, pointing out the importance of centering on the prevention and treatment of young stroke. At the same time, it hopes that the industry can concentrate on the prevention and treatment of young stroke, making precise policies in the future, and developing secondary prevention guidelines for the causes or risk factors of young stroke, so as to improve comprehensive stroke prevention and control system. On this basis, the health level of the whole population will be improved, and the life expectancy of residents will be extended, thus promoting the realization of the strategic goal of "Healthy China 2030".

Advances in nutritional support therapy for stroke prevention and treatment / 中华预防医学杂志

As a serious disease of death and disability, stroke constitutes a serious threat to human health. Because of stroke patients often have high-risk factors of malnutrition such as dysphagia and autonomic eating disorder, the hospitalization time, mortality and disability rate of stroke patients increases. Nutritional therapy can effectively improve the malnutrition of patients, which are of great significance for the treatment and rehabilitation of stroke and the prevention of its complications. Nutrients are important components of nutrition therapy, and different ways of nutrition therapy directly affect the effect of treatment. This article summarizes effects of nutrients and different nutritional treatments on stroke prevention, morbidity and treatment, and provides a theoretical basis and new thinking for further reducing the incidence rate of stroke, improving the quality of life in patients and reducing the financial burden of society and family.

Evaluation of three-dimensional high-resolution magnetic resonance imaging in the diagnosis of intracranial atherosclerotic stenosis / Evaluación de resonancia magnética tridimensional de alta resolución en el diagnóstico de la estenosis aterosclerótica intracraneal

SUMMARY: Intracranial artery stenosis (ICAS) was one of the main causes of ischemic stroke onset and recurrence. About 30 % of strokes were caused by intracranial artery stenosis. Intracranial artery stenosis had a high incidence in China and faced a high risk of recurrence for a long time. It affected patient safety and quality of life seriously. At the same time, it caused a heavy financial burden for the patient´s family. Therefore, early detection and accuracy of intracranial artery stenosis evaluation were extremely important. High-resolution magnetic resonance imaging (HR-MRI) had been widely used in clinical examinations, making up for the shortcomings of traditional vascular imaging methods that could only show the degree of luminal stenosis, making it possible to perform lumens, tube wall and plaque features of atherosclerotic intracranial arteries at the same time. There were still some controversies about the credibility of this technique in assessing the intracranial artery lumen stenosis. This article reviewed the application efficacy of HR-MRI technology in evaluating the degree of intracranial atherosclerotic stenosis.

RESUMEN: La estenosis de arterias intracraneales (ICAS) es una de las principales causas del ictus isquémico, como así también de su recurrencia. Alrededor del 30 % de los ataques cerebrovasculares son causados por estenosis de la arteria intracraneal. La estenosis de arterias intracraneales tiene una alta incidencia en China y enfrenta un alto riesgo de recurrencia, afectando gravemente la seguridad y la calidad de vida de los pacientes. Al mismo tiempo, supone una importante carga financiera para la familia de los pacientes. Por lo tanto, la detección temprana y la precisión de la evaluación de la estenosis de arterias intracraneales es extremadamente importante. La resonancia magnética de alta resolución (HR-MRI, por sus siglas en inglés) es utilizada ampliamente en los exámenes clínicos, compensando las deficiencias de los métodos tradicionales de imágenes vasculares que solo pueden mostrar el grado de estenosis luminal, haciendo posible el estudio de las características del lumen, pared vascular y la placa ateroesclerótica, de las arterias intracraneales afectadas, al mismo tiempo. Aún existen algunas controversias sobre la credibilidad de esta técnica en la evaluación de la estenosis del lumen de arterias intracraneales. En este artículo se revisó la eficacia de la aplicación de la tecnología HR-MRI para evaluar el grado de estenosis aterosclerótica intracraneal.

Stroke and Myocardial Infarction: Effects of the "Hiperdia" and "Mais Médicos" Programs on the Hospitalizations Trends in Brazil

Abstract Background Stroke and acute myocardial infarction (AMI) are cardiovascular diseases commonly characterized by the development of atheromatous plaques associated with major complications and high mortality rates. Objective To identify an epidemiological trend in hospitalizations due to stroke and AMI and to analyze the relationship between health programs applied in Primary Health Care, gender and the Federative Unit. Methods Ecological study with a time series design between 1998 and 2018, collecting data from all federal units in Brazil stratified by, gender and place of residence. There were analyzed Hospitalization Authorizations (AIH) for stroke and MI, consulting the Hospital Admissions System (SIH) of the Informatics Department of the National Health Service with p <0.05. Results From 1998 to 2018, the rate of hospitalization for AMI increased in Brazil approximately 42.58 events per 100 thousand inhabitants annually (p<0.001), while hospitalizations for stroke declined 32.17 cases (p=0.03). This pattern was observed in both sexes in AMI and stroke. There is also evidence of the effect of the Hiperdia (p<0.001) and Mais Médicos (p=0.001) program in reducing stroke and Hiperdia cases in mitigating the evolution of AMI cases (p = 0.0001). Conclusion Although these diseases remain as an important cause of death, stroke hospitalization has reduced significantly in the period evaluated. National programs as the Hiperdia and Mais Médicos showed an impact in the acute cases of strokes and AMI.

Diagnóstico de Fibrilação Atrial na Comunidade Utilizando Eletrocardiograma e Autorrelato: Análise Transversal do ELSA-Brasil / Atrial Fibrillation Diagnosis using ECG Records and Self-Report in the Community: Cross-Sectional Analysis from ELSA-Brasil

Resumo Fundamento: A fibrilação ou flutter atrial (FFA) é a arritmia cardíaca sustentada mais comum. Existem poucos dados sobre a epidemiologia da FFA na América do Sul. Objetivo: O presente estudo procurou descrever a epidemiologia clínica da FFA e o uso de anticoagulantes na avaliação da linha de base do Estudo Longitudinal da Saúde do Adulto (ELSA-Brasil). Métodos: Foram analisados dados de 13.260 participantes do ELSA-Brasil. A FFA foi definida pelo eletrocardiograma ou por autorrelato. Modelos de regressão logística foram construídos para analisar fatores associados à FFA. Este estudo também analisou se idade e sexo estavam associados ao uso de anticoagulantes para evitar acidente vascular cerebral. O nível de significância foi de 5%. Resultados: A idade mediana foi de 51 anos, e 7.213 (54,4%) participantes eram mulheres. A FFA foi detectada em 333 (2,5%) participantes. O aumento da idade (razão de chances [RC]:1,05; intervalo de confiança de 95% [IC95%]: 1,04-1,07), hipertensão (RC:1,44; IC95%:1,14-1,81) coronariopatia (RC: 5,11; IC95%:3,85-6,79), insuficiência cardíaca (RC:7,37; IC95%:5,00-10,87) e febre reumática (RC:3,38; IC95%:2,28-5,02) foram associadas à FFA. Dos 185 participantes com FFA e pontuação no CHA2DS2-VASc≥2, apenas 20 (10,8%) usavam anticoagulantes (50,0% entre aqueles com FFA no eletrocardiograma de linha de base). O uso de anticoagulantes nesse grupo foi associado a maior idade (1,8% vs 17,7% naqueles com idade ≤ 54 e ≥ 65 anos, respectivamente; p=0,013). Observou-se uma tendência ao menor uso de anticoagulantes em mulheres (7,1% vs. 16,4% em mulheres e homens, respectivamente; p=0,055). Conclusões: No recrutamento do ELSA-Brasil, 2,5% dos participantes tinham FFA. O baixo uso de anticoagulantes era comum, o que representa um desafio para os cuidados de saúde nesse cenário.

Abstract Background: Atrial fibrillation or flutter (AFF) is the most common sustained cardiac arrhythmia. Limited data can be found on AFF epidemiology in South America. Objective: The present study sought to describe the clinical epidemiology of AFF and the use of stroke prevention medication in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline assessment. Methods: This study analyzed data from 13,260 ELSA-Brasil participants. AFF was defined according to ECG recording or by self-report. Logistic regression models were built to analyze factors associated with AFF. This study also analyzed if age and sex were associated with anticoagulant use for stroke prevention. Significance level was set at 5%. Results: Median age was 51 years and 7,213 (54.4%) participants were women. AFF was present in 333 (2.5%) participants. Increasing age (odds ratio [OR]:1.05; 95% confidence interval [95%CI]: 1.04-1.07), hypertension (OR:1.44; 95%CI: 1.14-1.81), coronary heart disease (OR: 5.11; 95%CI: 3.85-6.79), heart failure (OR:7.37; 95%CI: 5.00-10.87), and rheumatic fever (OR:3.38; 95%CI: 2.28-5.02) were associated with AFF. From 185 participants with AFF and a CHA2DS2-VASc score ≥2, only 20 (10.8%) used anticoagulants (50.0% among those with AFF in the baseline ECG). Stroke prevention in this group was associated with a higher age (1.8% vs 17.7% in those aged ≤ 54 and ≥ 65 years, respectively; p=0.013). A trend towards a reduced anticoagulant use was observed in women (7.1% vs. 16.4% in women and men, respectively; p=0.055). Conclusions: At the ELSA-Brasil baseline, 2.5% of the participants had AFF. The lack of stroke prevention was common, which is an especially challenging point for healthcare in this setting.

The Anaortic Technique with Bilateral Internal Thoracic Artery Grafting - Filling the Gap in Coronary Artery Bypass Surgery

Abstract Coronary artery bypass grafting (CABG) has consolidated its role as the most effective procedure for treating patients with advanced atherosclerotic coronary artery disease, reducing the long-term risk of myocardial infarction and death compared to other therapies and relieving angina. Despite the recognized benefits afforded by surgical myocardial revascularization, a subset of higher-risk patients bears a more elevated risk of perioperative stroke. Stroke remains the drawback of conventional CABG and has been strongly linked to aortic manipulation (cannulation, cross‐clamping, and side-biting clamping for the performance of proximal aortic anastomoses) and the use of cardiopulmonary bypass. Adoption of off-pump CABG (OPCAB) is demonstrated to lower the risk of perioperative stroke, as well as reducing the risk of short-term mortality, renal failure, atrial fibrillation, bleeding, and length of intensive care unit stay. However, increased risk persists owing to the need for the tangential ascending aorta clamping to construct the proximal anastomosis. The concept of anaortic (aorta no-touch) OPCAB (anOPCAB) stems from eliminating ascending aorta manipulation, virtually abolishing the risk of embolism caused by aortic wall debris into the brain circulation. The adoption of anOPCAB has been shown to further decrease the risk of postoperative stroke, especially in higher-risk patients, entailing a step forward and a refinement of outcomes provided by the primeval OPCAB technique. Therefore, anOPCAB has been the recommended technique in patients with cerebrovascular disease and/or calcification or atheromatous plaque in the ascending aorta and should be preferred in patients with high-risk factors for neurological damage and stroke.

Pre-hospital Care for Suspected Stroke Patients, Cared for by Mobile Emergency Care Units in Northern Minas Gerais

Abstract Background Stroke management require rapid identification, assessment, and transport of patients to qualified health care centers. However, there is little description in the literature on the multiple challenges associated with the pre-hospital transport of suspected stroke patients. Objective To characterize the pre-hospital care provided to suspected stroke patients by the Brazilian Emergency Medical Service (SAMU in Portuguese), by means of a descriptive case study. Methods This is a descriptive study of a series of cases. Data from the SAMU regarding the responses to emergency calls from suspected stroke patients were collected. Independent reviewers confirmed the diagnostic hypothesis and all discordances were assessed using kappa statistics. Clinical data and transport times were described as frequency and proportion or central tendency and dispersion measures. Normality of continuous variable distribution was assessed using the Kolmogorov-Smirnov test. The Mann-Whitney U test was used for comparison of medians, with a 5% significance level. Results During the studied period, 556 suspected stroke patients were treated. The kappa index was 0.82 (95% CI 0.737 to 0.919) CI. In 74.7% of the cases, the symptom onset time was not recorded. The median time elapsed between the call for emergency services and the ambulance arrival was 18 minutes, and the median transport time was 38 minutes. A total of 34% of the patients were taken to referral hospitals for stroke. Conclusion This study revealed a low level of knowledge regarding the need to determine the exact time of symptom onset of suspected stroke patients. Also, the study showed the low rate of patients taken to referral hospitals. (Int J Cardiovasc Sci. 2021; [online].ahead print, PP.0-0)

Telemedicina en prevención secundaria y rehabilitación del accidente cerebrovascular durante la pandemia por COVID-19 / Telemedicine in secondary prevention and rehabilitation of stroke during the COVID-19 pandemic

Resumen La pandemia COVID-19 limitó el acceso de los pacientes post accidente cerebro vascular a los controles de seguimiento médico y a la rehabilitación, por lo cual decidimos incorporar herramientas tecnológicas gratuitas y accesibles para su continuación. Realizamos seguimiento remoto a 32 pacientes dados de alta en los primeros tres meses del período de aislamiento social preventivo obligatorio con el objetivo de continuar controles médicos, rehabilitación física y fonoaudiológica. El 100% adhirió al tratamiento médico y al auto-monitoreo de factores de riesgo; detectamos en forma temprana la interrupción de las terapias de rehabilita ción y mantuvimos la adherencia por medio de tele-rehabilitación. Los 32 pacientes mostraron disponibilidad para seguir con esta modalidad de atención, permitiendo continuar el seguimiento médico y supervisar la rehabilitación con la colaboración de las familias. Es una metodología accesible y de bajo costo que podría ser replicada y utilizada en instituciones de salud que traten enfermedades neurovasculares.

Abstract The COVID-19 pandemic resulted in limited access of post-stroke patients to their usual medical follow-up and rehabilitation. To continue these activities, we adopted a technology that is free and has universal access. We remotely followed 32 patients after discharge from the stroke unit during the mandatory lock-down. This allowed to continue with medical controls, physical therapy and speech pathology treatments. All patients fully complied with medical treatment and self-monitoring of vascular risk factors. Early discontinuation of rehabilitation therapies was identified and immediately compensated with tele-rehabilitation. All expressed their willingness to continue with this treatment modality. This strategy was successful to effectively continue medical follow-up and rehabilitation supervision with the collaboration of families, is an accessible and low-cost technology that could be replicated and used in health institutions that treat neurovascular diseases.

Impacto de la atención farmacéutica en la calidad del tratamiento con acenocumarol en pacientes con fibrilación auricular / Effects of pharmaceutical counseling on the effectiveness of anticoagulation in patients with atrial fibrillation

Background: Vitamin K antagonists such as acenocoumarol and warfarin are usually indicated for the treatment of Atrial Fibrillation (AF). The Therapeutic Range Time (TRT) is a quality of treatment indicator. Values greater than 65% are associated with significantly lower stroke and bleeding rates. Proper pharmaceutical care improves TRT. Aim: To evaluate the impact of pharmaceutical care in patients with AF treated with acenocoumarol. Material and Methods: We studied 41 patients using acenocoumarol for AF aged 71 ± 11 years (43% women). They received pharmaceutical counseling during 12 weeks. TRT was calculated retrospectively for the year before counseling and prospectively during the intervention period. Results: After receiving pharmaceutical counseling TRT improved from 29% at baseline to 46% at the end of the intervention (p < 0.01). After pharmaceutical care, the adherence of patients to drug treatment improved from 27% at baseline to 85% at the end of the study. The user satisfaction survey of the pharmaceutical care received showed a high degree of patient satisfaction. Conclusions: Pharmaceutical care in patients with oral anticoagulant treatment improves TRT of anticoagulation. It is accepted and positively evaluated by patients.

Popular knowledge of stroke in São Paulo: a cross-sectional study within the World Stroke Campaign

ABSTRACT BACKGROUND: Stroke is the second leading cause of death in Brazil and the main cause of disability. Inability to identify alarm signals causes delays in seeking emergency services, thereby leading to a worse prognosis. OBJECTIVES: To assess the population's knowledge of how to recognize and prevent stroke. DESIGN AND SETTING: Prospective cross-sectional study on data derived from a questionnaire that was administered during the 2016 World Stroke Campaign, launched in the city of São Paulo, Brazil. METHODS: Data on 806 interviewees were evaluated using descriptive statistics and univariate and multivariate analyses. RESULTS: Among all the interviewees, 52.1% knew how to conceptualize stroke; 70.07% knew someone who had suffered a stroke; and 29.03% listed three or more risk factors. Only 27.5% mentioned controlling high blood pressure as a preventive measure. In the event of witnessing a stroke, 57.8% would call the emergency service and 2.9% would check the timing. Less educated individuals were 5.6 times more likely (95% confidence interval, CI 3.45-9.02) to have poor knowledge of stroke, compared with the more educated group. Knowing someone who had had a stroke reduced the chances of not knowing the terms relating to the disease (odds ratio, OR = 0.56; 95% CI 0.4-0.78). CONCLUSIONS: Despite the severity and prevalence of stroke, the population still has little information on this disease. In this context, the importance of mounting campaigns to improve prevention and treatment and to contribute to healthcare policies becomes evident.

Cardiología digital (e-Cardiología): herramientas de utilidad para el diagnóstico y el manejo del paciente con fibrilación auricular / Digital Cardiology (e-Cardiology): useful tools for diagnosis and management of atrial fibrillation / Cardiologia digital (e-Cardiologia): ferramentas úteis para o diagnóstico e tratamiento de pacientes com fibrilação atrial

La tecnología digital móvil (mSalud), recurso aún subutilizado, tiene el potencial para transformarse en un auxiliar imprescindible en la práctica clínica, en particular en Cardiología. La fibrilación auricular es la arritmia más frecuente, cuya prevalencia aumenta con la edad y tiene como complicación más temida el accidente cerebrovascular. Su prevención depende de un diagnóstico oportuno, una adecuada estratificación de riesgo y el uso de anticoagulantes orales. Sin embargo, es con frecuencia paroxística y asintomática, lo que dificulta su diagnóstico. El aporte de la tecnología mediante el desarrollo de aplicaciones para celulares, relojes, dispositivos portátiles o implantables que registran el ritmo cardíaco y permiten el monitoreo prolongado, ambulatorio y a distancia facilitan su detección. Se repasan las principales evidencias que justifican la aplicación de estas estrategias de tamizaje, cuando está indicado realizarlo, cómo y a quiénes hacerlo. Por último, se plantea también la utilidad de estas estrategias de monitoreo prolongado en el manejo y la prevención de la fibrilación auricular.

The mobile digital technology (mHealth), a tool still underutilized, has the potential to become an essential aid in clinical practice, particularly in Cardiology. Atrial fibrillation is the most frequent arrhythmia whose prevalence increases with age and its most feared complication is cerebrovascular accident. Its prevention depends on a timely diagnosis, an adequate risk stratification and the use of oral anticoagulants. However, it is frequently paroxysmal and asymptomatic, which makes its diagnosis difficult. The contribution of technology through the development of applications for cell phones, watches, portable or implantable devices that record the heart rhythm and allow prolonged, outpatient and remote monitoring, facilitate its detection. The main evidences that justify the application of these screening strategies are reviewed, when it is indicated to perform it, how and to whom to do it. Finally, the usefulness of these prolonged monitoring strategies in the management and prevention of atrial fibrillation is also considered.

A utilização da tecnologia digital móvel (m-Saúde), ainda pouco utilizada, tem potencial para se tornar um auxílio essencial na prática clínica, principalmente na Cardiologia. A fibrilação atrial é a arritmia mais frequente, cuja prevalência aumenta com a idade e sua complicação mais temida é o acidente vascular cerebral. Sua prevenção depende de um diagnóstico oportuno, de uma estratificação de risco adequada e do uso de anticoagulantes orais. Porém, freqüentemente é paroxística e assintomática, o que dificulta seu diagnóstico. A contribuição da tecnologia por meio do desenvolvimento de aplicativos para telefones celulares, relógios, dispositivos portáteis ou implantáveis ​​que registram o ritmo cardíaco e permitem monitoramento prolongado, ambulatorial e remoto, facilitam sua detecção. São revisadas as principais evidências que justificam a aplicação dessas estratégias de rastreamento, quando é indicado fazê-lo, como e para quem fazê-lo. Finalmente, a utilidade dessas estratégias de monitoramento prolongado no manejo e prevenção da fibrilação atrial também é considerada.
