Advances in anticoagulant therapy for cirrhosis combined with atrial fibrillation / 中华肝脏病杂志

Relevant research in recent years has demonstrated that the atrial fibrillation occurrence rate is significantly higher in patients with cirrhosis. The most common indication for long-term anticoagulant therapy is chronic atrial fibrillation. The use of anticoagulant therapy greatly reduces the incidence rate of ischemic stroke. Patients with cirrhosis combined with atrial fibrillation have an elevated risk of bleeding and embolism during anticoagulant therapy due to cirrhotic coagulopathy. At the same time, the liver of such patients will go through varying levels of metabolism and elimination while consuming currently approved anticoagulant drugs, thereby increasing the complexity of anticoagulant therapy. This article summarizes the clinical studies on the risks and benefits of anticoagulant therapy in order to provide a reference for patients with cirrhosis combined with atrial fibrillation.

Effectiveness and safety of Shexiang Baoxin Pill (MUSKARDIA) in patients with stable coronary artery disease and concomitant diabetes mellitus: a subgroup analysis of a randomized clinical trial / 中华医学杂志(英文版)

BACKGROUND@#Preliminary studies have indicated that Shexiang Baoxin Pill (MUSKARDIA) has a coronary artery dilation effect and increases the coronary blood flow, relieving the symptoms of angina. This study aimed to evaluate the benefit of MUSKARDIA on patients with stable coronary artery disease (CAD) and diabetes mellitus (DM).@*METHODS@#This was a subgroup analysis of a multicenter, randomized, placebo-controlled phase IV trial. CAD patients with a medical history of DM or baseline fasting blood glucose (FBG) ≥7.0 mmol/L were grouped according to the treatment (standard therapy plus MUSKARDIA or placebo). The primary outcome was major adverse cardiovascular events (MACEs), which was the composite outcome of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. The secondary outcome was the composite outcome of all-cause death, non-fatal myocardial infarction, non-fatal stroke, hospitalization for unstable angina or heart failure, and coronary angioplasty.@*RESULTS@#MACEs occurred in 2.6% (9/340) and 4.8% (18/376) of patients in the MUSKARDIA and placebo groups, respectively ( P  = 0.192). Secondary composite outcome was significantly less frequent with MUSKARDIA than with placebo (15.3% [52/340] vs . 22.6% [85/376], P  = 0.017). Risk of MACEs (hazard ratio [HR] = 0.69, 95% confidence interval [CI]: 0.31-1.57) was comparable between two groups. In patients with uncontrolled DM (≥4 measurements of FBG ≥7 mmol/L in five times of follow-up), the risk of secondary outcome was significantly lower with MUSKARDIA (5/83, 6.0%) than with placebo (15/91, 16.5%) (HR = 0.35, 95%CI: 0.13-0.95).@*CONCLUSION@#As an add-on to standard therapy, MUSKARDIA shows a trend of reduced MACEs in patients with stable CAD and DM. Furthermore, MUSKARDIA may reduce the frequency of all-cause death, hospitalization, and coronary angioplasty in this population, especially in those with uncontrolled DM.@*TRIAL REGISTRATION@#ChiCTR.org.cn, ChiCTR-TRC-12003513.

Effect of Age and Sex on Stroke Mortality of Young and Middle-aged Adults in China, 2002-2019, and Predictions to 2030 / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to examine the trends in stroke mortality among young and middle-aged adults in China.@*METHODS@#Data were obtained from the China national vital registration system. Significant changes in mortality were assessed by Joinpoint regression. Age-period-cohort analysis was used to explain the reasons for the changes. Future mortality and counts were predicted by the Bayesian age-period-cohort model.@*RESULTS@#Between 2002 and 2019, a total of 6,253,951 stroke mortality in young and middle-aged adults were recorded. The age-adjusted mortality rates (AAMRs) of women showed a downward trend. The annual percent changes (APC) were -3.5% (-5.2%, -1.7%) for urban women and -2.8% (-3.7%, -1.9%) for rural women. By contrast, the AAMRs per 100,000 for rural men aged 25-44 years continued to rise from 9.40 to 15.46. The AAMRS for urban men aged 25-44 years and urban and rural men aged 45-64 years did not change significantly. Between 2020 and 2030, the projected stroke deaths are 1,423,584 in men and 401,712 in women.@*CONCLUSION@#Significant sex and age disparities in the trends of stroke mortality among young and middle-aged adults were identified in China. Targeted health policy measures are needed to address the burden of stroke in the young generation, especially for rural men, with a focus on the prevention and management of high risk factors.

Projected burden of stroke in China through 2050 / 中华医学杂志(英文版)

BACKGROUND@#Stroke is the leading cause of death in China, and predicting the stroke burden could provide essential information guiding the setting of medium- and long-term health policies and priorities. The study aimed to project trends associated with stroke burden in China through 2050, not only in terms of incidence and mortality but also for prevalence and disability-adjusted life years (DALYs).@*METHODS@#Data on stroke rates in incidence, prevalence, deaths, and DALYs in China between 1990 and 2019 were obtained from a recent Global Burden of Disease study. Demographic-specific trends in rates over time were estimated using three models: the loglinear model, the Lee-Carter model, and a functional time series model. The mean absolute percentage error and the root mean squared error were used for model selection. Projections up to 2050 were estimated using the best fitting model. United Nations population data were used to project the absolute numbers through 2050.@*RESULTS@#From 2019 to 2050, the crude rates for all measures of the stroke burden are projected to increase continuously among both men and women. We project that compared with those in 2019, the incidence, prevalence, deaths, and DALYs because of stroke in China in 2050 will increase by 55.58%, 119.16%, 72.15%, and 20.04%, respectively; the corresponding increases in number were 2.19, 34.27, 1.58, and 9.21 million. The age-standardized rate is projected to substantially decline for incidence (8.94%), death (40.37%), and DALYs (43.47%), but the age-standardized prevalence rate is predicted to increase by 10.82%. By 2050, the burden of stroke among the population aged ≥65 years will increase significantly: by 104.70% for incidence, by 218.48% for prevalence, by 100.00% for death, and by 58.93% for DALYs.@*CONCLUSIONS@#With the aging population in China increasing over the next three decades, the burden of stroke will be markedly increased. Continuous efforts are needed to improve stroke health care and secondary prevention, especially for older adults.

On the other hand, heart disease, arterial hypertension, and previous cerebrovascular disease were the most significant associated conditions with a ratio of cross products in exposed of 3.55 and 2.97 and an attributable risk in exposed of 71.8 and 66.3 percent, respectively. Conclusions: Modifiable risk factors such as hypercholesterolemia, obesity, sedentary lifestyle, inadequate nutritional habits and the use of contraceptive methods increased the probability of suffering from cerebrovascular disease in the women studied(AU)

Association between metabolically healthy obesity and incident risk of stroke in adult aged over 40 from rural Henan province / 中华预防医学杂志

Objective: To investigate the association between metabolically healthy obesity and the incident risk of stroke in people aged ≥40 years from rural areas of Henan Province. Methods: During 2007 to 2008, 20 194 residents aged ≥18 years were selected for baseline examination by random cluster sampling and 17 265 participants were followed up during 2013 to 2014. According to the aim of current study, a total of 11 864 eligible subjects were included in this post-hoc analysis. Depending on body mass index and metabolic status, subjects were divided into four groups: metabolically healthy normal weight, metabolically healthy obesity, metabolically abnormal normal weight and metabolically abnormal obesity. Multivariate logistic regression model was used to analyze the relationship between metabolically healthy obesity and the risk of stroke. Results: The median (Q1, Q3) age of study participants was 54(46, 61) years, and 4 526 participants were men. During the mean follow-up of 6 years, the cumulative incidence of stroke was 7.16%. The incidence of stroke in metabolically healthy normal weight, metabolically healthy obesity, metabolically abnormal normal weight, and metabolically abnormal obesity were 3.73%, 4.61%, 8.99% and 9.38%, respectively (χ²=117.458, P<0.001). After adjusting possible confounding factors, compared with metabolically healthy normal weight, the risk of stroke was significantly increased in the metabolically healthy obesity group, metabolically abnormal normal weight group and metabolically abnormal obesity group with the odds ratio (OR) and 95% confidence interval (CI) of 1.52(1.10-2.12), 2.11(1.61-2.77) and 2.78(2.18-3.55), respectively. Stratified analysis showed that the risk of stroke was significantly higher in metabolically healthy obesity people aged 40-59 years compared with metabolically healthy normal weight group (OR=2.12, 95%CI: 1.36-3.30). Conclusion: Metabolically healthy obesity, metabolically abnormal normal weight and metabolically abnormal obesity are positively associated with the risk of stroke.

Report on Cardiovascular Health and Diseases in China 2021: An Updated Summary / 生物医学与环境科学（英文）

In 2019, cardiovascular disease (CVD) accounted for 46.74% and 44.26% of all deaths in rural and urban areas, respectively. Two out of every five deaths were due to CVD. It is estimated that about 330 million patients suffer from CVD in China. The number of patients suffering from stroke, coronary heart disease, heart failure, pulmonary heart disease, atrial fibrillation, rheumatic heart disease, congenital heart disease, lower extremity artery disease and hypertension are 13.00 million, 11.39 million, 8.90 million, 5.00 million, 4.87 million, 2.50 million, 2.00 million, 45.30 million, and 245.00 million, respectively. Given that China is challenged by the dual pressures of population aging and steady rise in the prevalence of metabolic risk factors, the burden caused by CVD will continue to increase, which has set new requirements for CVD prevention and treatment and the allocation of medical resources in China. It is important to reduce the prevalence through primary prevention, increase the allocation of medical resources for CVD emergency and critical care, and provide rehabilitation services and secondary prevention to reduce the risk of recurrence, re-hospitalization and disability in CVD survivors. The number of people suffering from hypertension, dyslipidemia and diabetes in China has reached hundreds of millions. Since blood pressure, blood lipids, and blood glucose levels rise mostly insidiously, vascular disease or even serious events such as myocardial infarction and stroke often already occured at the time of detection in this population. Hence, more strategies and tasks should be taken to prevent risk factors such as hypertension, dyslipidemia, diabetes, obesity, and smoking, and more efforts should be made in the assessment of cardiovascular health status and the prevention, treatment, and research of early pathological changes.

Onset and Recurrence Characteristics of Chinese Patients with Noncardiogenic Ischemic Stroke in Chinese Medicine Hospital / 中国结合医学杂志

OBJECTIVE@#To delineate the onset and recurrence characteristics of noncardiogenic ischemic stroke patients in China.@*METHODS@#A prospective, multicenter and registry study was carried out in 2,558 patients at 7 representative clinical sub-centers during November 3, 2016 to February 17, 2019. A questionnaire was used to collect information of patients regarding CM syndromes and constitutions and associated risk factors. Additionally, stroke recurrence was defined as a primary outcome indicator.@*RESULTS@#A total of 327 (12.78 %) patients endured recurrence events, 1,681 (65.72%) were men, and the average age was 63.33 ± 9.45 years. Totally 1,741 (68.06%) patients suffered first-ever ischemic stroke, 1,772 (69.27%) patients reported to have hypertension, and 1,640 (64.11%) of them reported dyslipidemia, 1,595 (62.35%) patients exhibited small-artery occlusion by The Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification. Specifically, 1,271 (49.69%) patients were considered as qi-deficient constitution, and 1,227 (47.97%) patients were determined as stagnant blood constitution. There were 1,303 (50.94%) patients diagnosed as blood stasis syndrome, 1,280 (50.04%) patients exhibited phlegm and dampness syndrome and 1,012 (39.56%) patients demonstrated qi deficiency syndrome. And 1,033 (40.38%) patients declared intracranial artery stenosis, and 478 (18.69%) patients reported carotid artery stenosis. The plaque in 1,508 (41.36%) patients were of mixed. Particularly, 41.09% of them demonstrated abnormal levels of glycated hemoglobin levels.@*CONCLUSIONS@#Recurrence in minor and small-artery stroke cannot be ignored. Hypertension, dyslipidemia, abnormal HbA1c, intracranial artery stenosis and carotid plaque were more common in stroke patients. Particularly, phlegm-dampness and blood stasis syndromes, as well as qi deficiency and blood stasis constitutions, were still the main manifestations of stroke.

Risk score elaboration for stroke in cardiac surgery

Abstract Introduction: Stroke is a complication that causes considerable morbidity and mortality during the heart surgery postoperative period (incidence: 1.3 to 5%; mortality: 13 to 41%). Models for assessing the risk of stroke after heart surgery have been proposed, but most of them do not evaluate postoperative morbidity. The aim of this study was to develop a risk score for postoperative stroke in patients who undergo heart surgery with cardiopulmonary bypass. Methods: A cohort study was conducted with data from 4,862 patients who underwent surgery from 1996 to 2016. Logistic regression was used to assess relationships between risk factors and stroke. Data from 3,258 patients were used to construct the model. The model's performance was then validated using data from the remainder of the patients (n=1,604). The model's accuracy was tested using the area under the receiver operating characteristic (ROC) curve. Results: The prevalence of stroke during the postoperative period was 3% (n=149); 59% of the patients who exhibited this outcome were male, 51% were aged ≥ 66 years, and 31.5% of the patients died. The variables that remained as independent predictors of the outcome after multivariate analysis were advanced age, urgent/emergency surgery, peripheral arterial occlusive disease, history of cerebrovascular disease, and cardiopulmonary bypass time ≥ 110 minutes. The area under the ROC curve was 0.71 (95% confidence interval 0.66 - 0.75). Conclusion: We were able to develop a risk score for stroke after heart surgery. This score classifies patients as low, medium, high, or very high risk of a surgery-related stroke.

ABO blood group system and occurrence of ischemic stroke / Sistema ABO de grupos sanguíneos e ocorrência de acidente vascular cerebral isquêmico

ABSTRACT Background: Ischemic stroke (IS) is a multifactorial disease that presents high rates of morbimortality in Brazil. Several studies proved that there is a link between the ABO blood group system and the occurrence of thrombotic events. Nonetheless, its association with IS is not well established. Objective: For that reason, the purpose hereof was to investigate the relation between the ABO blood groups and the occurrence of IS in a Brazilian cohort of cerebrovascular diseases. Methods: Five hundred and twenty-nine subjects were included over 12 months, from which 275 presented an IS episode and 254 composed the control group. Blood samples were drawn for direct and reverse serotyping. The control and IS groups were compared regarding the traditional risk factors and the distribution of the ABO blood groups. Results: The IS group presented a higher prevalence of systemic arterial hypertension (SAH), diabetes mellitus, smoking habits, family history, cardiopathy, and sedentary lifestyle in comparison with the control group. The AB blood type prevailed among the patients (5.1 vs. 1.6%; p<0.05) and this group had more SAH cases in comparison with the O type group (92.9 vs. 67.3%; p<0.05). Conclusions: Our results suggest that the occurrence of IS is more frequent among patients of the AB blood type.

RESUMO Antecedentes: O acidente vascular cerebral isquêmico (AVCI) é uma doença multifatorial que apresenta altas taxas de morbimortalidade no Brasil. Vários estudos provaram que existe uma ligação entre o sistema ABO de grupos sanguíneos e a ocorrência de eventos trombóticos. No entanto, sua associação com AVCI não está bem estabelecida. Objetivo: Por essa razão, o objetivo deste trabalho foi investigar a relação entre os grupos sanguíneos ABO e a ocorrência de AVCI em uma coorte brasileira de doenças cerebrovasculares. Métodos: Ao longo de 12 meses foram incluídos 529 indivíduos, dos quais 275 apresentaram um episódio de AVCI e 254 compuseram o grupo controle. Amostras de sangue foram coletadas para sorotipagem direta e reversa. Os grupos controle e AVCI foram comparados em relação aos fatores de risco tradicionais e à distribuição dos grupos sanguíneos ABO. Resultados: O grupo AVCI apresentou maior prevalência de hipertensão arterial sistêmica (HAS), diabetes mellitus, tabagismo, história familiar, cardiopatia e estilo de vida sedentário em comparação ao grupo controle. O tipo sanguíneo AB prevaleceu entre os pacientes (5,1 vs. 1,6%; p<0,05) e apresentou mais casos de HAS em comparação ao tipo O (92,9 vs. 67,3%; p<0,05). Conclusões: Nossos resultados sugerem que a ocorrência de AVCI é mais frequente entre os pacientes do tipo sanguíneo AB.

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.

Difficulty in taking medication and stroke among older adults with systemic arterial hypertension: the Fibra Study / Dificuldade em tomar medicamentos e acidente vascular encefálico em idosos com hipertensão arterial sistêmica: Estudo Fibra

Abstract This article aims to investigate whether difficulty in taking medication is associated with stroke among older adults with Systemic Arterial Hypertension (SAH) and to explore their association with living arrangements. Cross-sectional study was based on 3,502 older adults with SAH from the four universities pole of Frailty in Brazilian Older People (Fibra) Study, Brazil, including 14 municipalities of the five Brazilian regions. We used the medical diagnosis of stroke and difficulty in taking medications (self-reported difficulty and financial difficulty affording prescribed medications). Multivariate analysis was performed using logistic regression. Differently from women, older men with SAH, which report difficulty in taking medication (unintentional non-adherence), have higher odds of stroke. When stratified by living arrangements, those living with a partner have even higher odds of stroke compared to those without difficulty in taking medication and living alone. None association was found for difficulty affording prescribed medication for both men and women. Unintentional difficulty in taking medication plays a role in SAH treatment among men. Primary care strategies for controlling blood pressure should not be focus only on patients but targeting spouses as well.

Resumo O objetivo deste artigo é investigar se a dificuldade em tomar medicamentos está associada ao acidente vascular encefálico (AVE) entre idosos com hipertensão arterial sistêmica (HAS) e explorar esta associação com arranjos familiares. Estudo seccional baseado em 3.502 idosos com HAS dos quatro polos do Estudo Fibra, Brasil, incluindo 14 cidades das cinco regiões brasileiras. Foi usado o diagnóstico médico de AVE e a dificuldade em tomar medicamentos (dificuldade autorrelatada e dificuldade financeira). Utilizou-se a regressão logística na análise multivariada. Diferentemente das mulheres, homens com HAS que relataram dificuldade em tomar medicamentos (não adesão não intencional) apresentam maior chance de ter AVE. Quando estratificado por arranjos familiares, homens que moravam com o cônjuge apresentaram chance ainda maior de ter AVE, quando comparados com aqueles sem dificuldade em tomar medicamentos e que vivem sozinhos. Nenhuma associação foi encontrada para dificuldade financeira, tanto para mulheres quanto para homens. Dificuldades não intencionais em tomar medicamentos têm um papel importante no controle da HAS entre homens. Estratégias de controle da pressão arterial realizadas na atenção primária não devem focar apenas nos pacientes, mas nos cônjuges destes pacientes.

Embolic Stroke of Undetermined Source (ESUS) and Stroke in Atrial Fibrillation Patients: not so Different after all?

Abstract Background: Stroke related to atrial fibrillation (AF) is associated with high recurrence and mortality rates. Embolic Stroke of Undetermined Source (ESUS) is associated with fewer vascular risk factors, less disability, and a high recurrence rate. Objective: To compare risk factors, functional outcomes and the occurrence of primary endpoint (a composite of recurrent stroke, cardiovascular death, and myocardial infarction) between AF stroke and ESUS patients. Method: A retrospective analysis was conducted including all consecutive patients with first-ever ischemic stroke admitted to the Hospital de Clinicas (Clinical Hospital) of the Federal University of Paraná from October 2012 to January 2017 (n=554). There were 61 patients with stroke due to AF and 43 due to ESUS. Both groups were compared for demographic characteristics and vascular risk factors. Logistic regression models were performed to assess the impact of each variable on the primary endpoint in a 12-month follow-up. Statistical significance was considered for p-values < 0.05. Results: ESUS patients, as compared to AF patients, were younger and more likely to be smokers. ESUS patients presented a mean CHADS2VASc score of 4, while the AF group presented a score of 5 (p <0.001). The primary endpoint was observed in 9 (20.9%) ESUS and 11 (18.0%) AF patients over a 12-month period (p=0.802). Higher glucose levels upon hospital admission (p=0.020) and a higher modified Rankin Scale upon hospital discharge (p=0.020) were predictors of the primary endpoint occurrence. Conclusion: AF and ESUS stroke patients presented very similar independence rates upon hospital discharge and outcomes after 12 months, despite some baseline differences, including stroke recurrence, vascular death, and myocardial infarction.

Factores de riesgo para enfermedad cerebrovascular en el adulto mayor / Risk Factors for Cerebrovascular Disease in the Older Adult

Introducción: La vejez está subvalorada, poco se piensa en el bienestar físico y psicosocial del anciano. La enfermedad cerebrovascular tiene como factores de riesgo comorbilidades como la hipertensión arterial, la diabetes mellitus, la dislipidemia, cardiopatías o malos estilos de vida como el consumo de cigarrillo, la obesidad y la poca actividad física, todos estos comunes en esta etapa de la vida. Objetivo: Identificar los factores de riesgo que presentan los adultos mayores para sufrir enfermedad cerebrovascular de un centro gerontológico de la ciudad de Medellín. Métodos: Fue una investigación descriptiva, de tipo transversal; se indagaron 37 adultos mayores con historias clínicas y exámenes de laboratorio. Se midieron los niveles de hemoglobina glicosilada, colesterol total, colesterol de baja densidad, colesterol de alta densidad y triglicéridos. Resultados: Se evidenció que la población era en su mayoría de sexo masculino con 51,4 por ciento y el sexo femenino con 48,6 por ciento; con rango de edad entre 60 y 70 años el 51,4 por ciento. Los factores de riesgo más relevantes fueron el índice de masa corporal mayor o igual a 25 con (75,7 por ciento), hipertensión arterial y no realizar actividad física. Conclusiones: Se logró determinar los principales factores de riesgo que tienen estos adultos mayores para sufrir enfermedad cerebrovascular; con resultados algunos similares y otros diferentes a estudios a nivel mundial. Con actividades de promoción y prevención se pueden intervenir estilos de vida de la población(AU)

Introduction: Old age is undervalued; little is thought about the physical and psychosocial well-being of the elderly. Among the risk factors of cerebrovascular disease, there are comorbidities, such as high blood pressure, diabetes mellitus, dyslipidemia and cardiopathies, or poor lifestyles like cigarette smoking, obesity and little physical activity, all of which are common at this stage of life. Objective: To identify, in a gerontological center in Medellín City, the risk factors that older adults present for being affected by cerebrovascular disease. Methods: This was a descriptive and cross-sectional research carried out with 37 older adults with medical antecedents and laboratory tests. The levels of glycated hemoglobin, total cholesterol, low-density and high-density cholesterol, as well as triglycerides were measured. Results: It was evidenced that the population was mostly male (51.4 por ciento), while females accounted for 48.6 por ciento. Their age range was mostly between 60 and 70 years (51.4 por ciento). The most relevant risk factors were body mass index greater than or equal to 25 (75.7 por ciento), arterial hypertension and not doing any physical activity. Conclusions: It was possible to determine the main risk factors for these older adults being affected by cerebrovascular disease; in this respect, some results were similar to and others were different from studies worldwide. With promotion and prevention activities, lifestyles of the population can be intervened(AU)

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.

AISYF: first national, prospective, multicenter study of young patients with stroke in Argentina / AISYF: primer estudio nacional, prospectivo y multicéntrico de pacientes jóvenes con ataque cerebral en Argentina

Abstract Up to 15% of all strokes affect young patients and the incidence of ischemic stroke in this population is rising. Nevertheless, there is limited information of cerebrovascular events in this population both in our country and in Latin America. The aim of our study was to evaluate the clinical characteristics and risk factors of young adults with stroke in Argentina. This is a prospective, multicenter study of stroke in young adults (18 - 55 years) in Argentina. Patients presenting with a cerebrovascular event within 180 days were included. Stroke subtypes were classified according to TOAST criteria. A total number of 311 patients were enrolled (men 53.9%, mean age: 43.3 years). Ischemic strokes occurred in 91.8% (brain infarcts 82.6%, transient ischemic attack 9.2%) and hemorrhagic strokes in 8.2%. The most frequent vascular risk factors (including ischemic and hemorrhagic strokes) were: hypertension 120 (41%), smoking 92 (31.4%), dyslipidemia 81 (27.6%) and, over weight/obesity: 74 (25.3%). Stroke subtypes were: large artery disease 12.3%, cardioembolism 7.5, small artery occlusion 11.5%, other defined etiology 27.1%, and undetermined etiology 41.6%. Our study demonstrates that vascular risk factors are very frequent in young adults with stroke. Our findings underline that urgent strategies are required for primary and secondary stroke prevention in this group of patients.

Resumen Aproximadamente un 15% de todos los ataques cerebrovasculares afectan a pacientes jóvenes y su incidencia estaría en aumento. Existe escasa información sobre el ataque cerebral en esta población tanto en nuestro país como en Latinoamérica. El objetivo de nuestro estudio fue evaluar las características clínicas y los factores de riesgo de los adultos jóvenes con ictus en Argentina. Realizamos un estudio prospectivo y multicéntrico en adultos jóvenes (18-55 años) en Argentina, que presentaron un evento cerebrovascular dentro de los 180 días previos. Los subtipos de ictus se clasificaron según los criterios de TOAST. Se incluyeron un total de 311 pacientes (hombres 53.9%, edad media: 43,3 años). Los ataques cerebrovasculares isquémicos ocurrieron en el 91.8% (infartos cerebrales 82.6%, ataque isquémico transitorio 9.2%) y los eventos hemorrágicos correspondieron al 8.2%. Los factores de riesgo vascular más frecuentes (incluyendo los eventos isquémicos y hemorrágicos) fueron: hipertensión 120 (41%), tabaquismo 92 (31.4%), dislipidemia 81 (27.6%) y sobrepeso/obesidad: 74 (25.3%). Los subtipos de ictus isquémicos fueron: arteriopatía de gran vaso 12.3%, cardioembolismo 7.5%, oclusión de pequeña arteria 11.5%, otra etiología definida 27.1% y etiología indeterminada 41.6%. Los factores de riesgo vascular son muy frecuentes en los adultos jóvenes con ictus. Nuestros hallazgos subrayan que se requieren estrategias urgentes para la prevención primaria y secundaria del ictus en este grupo particular de pacientes en nuestro país.
