Abstract Background Dental anesthetic management in implantable cardioverter defibrillator (ICD) recipients with cardiac channelopathies (CCh) can be challenging due to the potential risk of life-threatening arrhythmias and appropriate ICD therapies during procedural time. Objectives The present study assessed the hypothesis that the use of local dental anesthesia with 2% lidocaine with 1:100,000 epinephrine or without a vasoconstrictor can be safe in selected ICD and CCh patients, not resulting in life-threatening events (LTE). Methods Restorative dental treatment under local dental anesthesia was made in two sessions, with a wash-out period of 7 days (cross-over trial), conducting with a 28h - Holter monitoring, and 12-lead electrocardiography, digital sphygmomanometry, and anxiety scale assessments in 3 time periods. Statistical analysis carried out the paired Student’s t test and the Wilcoxon signed-rank test. In all cases, a significance level of 5% was adopted. All patients were in stable condition with no recent events before dental care. Results Twenty-four consecutive procedures were performed in 12 patients (9 women, 3 men) with CCh and ICD: 7 (58.3%) had long QT syndrome (LQTS), 4 (33.3%) Brugada syndrome (BrS), and 1 (8.3%) Catecholaminergic polymorphic ventricular tachycardia (CPVT). Holter analysis showed no increased heart rate (HR) or sustained arrhythmias. Blood pressure (BP), electrocardiographic changes and anxiety measurement showed no statistically significant differences. No LTE occurred during dental treatment, regardless of the type of anesthesia. Conclusion Lidocaine administration, with or without epinephrine, can be safely used in selected CCh-ICD patients without LTE. These preliminary findings need to be confirmed in a larger population with ICD and CCh.

Abstract Objective: to estimate the seroprevalence of arboviruses, syphilis, HIV, and hepatitis B (HBV) in Healthcare Workers (HCW). Methods: a survey among HCW among was randomly selected in a city in Bahia-Brazil. The research used a structured questionnaire, which collected sociodemographic, occupational, and health information in 2019. Rapid immunochromatographic tests were used to track infections. Thus, positive results for arboviruses, syphilis, HIV, and HBV indicated seropositivity for the respective infection. In addition, simultaneous detection of antibodies for zika (ZIKV) and dengue (DENV) viruses indicated seropositivity for flavivirus infection. Results: a total of 453 HCW were included, 82.8% were women. Most HCW (55.1%) reported contact with biological material; 5.2% reported injuries with biological material. The seroprevalence was 34.7% (95%CI:30.1-39.4) for dengue, 1.7% (95%CI:0.7-3.4) for zika, 9.9% (95%CI:7.2-13.2) for chikungunya, and 39.9% (95%CI:35.2-44.7) for flavivirus (ZIKV+DENV); with 21.9% (95%CI:18.1-26.2) being negative to all arboviruses. Seropositivity to arboviruses increased with age and was higher among endemic disease control agents. Three HCW tested positive for HBV (HBsAg); no HIV cases were detected. Conclusion: a high percentage of HCW was exposed to infectious agents (contact with biological material and/or exposure to arboviruses). Among the necessary conditions for preventing infections in the work environment, the following stand out: monitoring of infectious diseases among HCW, surveillance of work environments, and measures to control occupational exposures, such as the availability of repellents.

Resumo Objetivo: estimar soroprevalências de arboviroses, sífilis, HIV e Hepatite B (VHB) em trabalhadores de saúde (TS). Métodos: inquérito entre TS selecionados por amostragem aleatória, em uma cidade da Bahia - Brasil. Pesquisa realizada em 2019 por meio de questionário estruturado, que coletou informações sociodemográficas, ocupacionais e de saúde. Testes imunocromatográficos rápidos foram utilizados para rastrear as infecções; dessa forma, resultados positivos para arboviroses, sífilis, HIV e VHB indicaram soropositividade para a respectiva infecção. Além disso, detecção simultânea de anticorpos para zika (ZIKV) e dengue (DENV) indicou soropositividade para infecção por flavivírus. Resultados: 453 TS foram incluídos, sendo 82,8% do sexo feminino. A maioria (55,1%) relatou contato com material biológico; 5,2% referiram acidentes com material biológico. Encontrou-se soroprevalência de 34,7% (IC95%:30,1-39,4) para dengue, 1,7% (IC95%:0,7-3,4) para zika, 9,9% (IC95%:7,2-13,2) para chikungunya e 39,9% (95%CI:35,2-44,7) para flavivírus (ZIKV+DENV); 21,9% (IC95%:18,1-26,2) foram negativos para todos os arbovírus. Soropositividade para arbovírus aumentou com a idade e foi maior entre agentes de combate a endemias. Três TS testaram positivo para VHB (HBsAg); nenhum para HIV. Conclusão: elevado percentual de TS estava exposto a agentes infecciosos (contato com material biológico e/ou exposição a arbovírus). Entre as condições necessárias à prevenção de infecções no ambiente de trabalho, destacam-se: monitoramento de infecções entre TS, vigilância dos ambientes laborais e medidas de controle de exposições ocupacionais, como disponibilidade de repelentes.

Abstract Introduction Fibromyalgia is a complex, generalized, and diffuse chronic musculoskeletal pain. Pharmacological approaches are widely used to relieve pain and increase quality of life. Low-Dose Naltrexone (LDN) was shown to increase the nociceptive threshold in patients with fibromyalgia. Transcranial Direct Current Stimulation (tDCS) is effective for pain management. Objective The purpose of this study was to evaluate the analgesic and neuromodulatory effects of a combination of LDN and tDCS in patients with fibromyalgia. Methods This was a randomized, double-blinded, parallel, placebo/sham-controlled trial (NCT04502251; RBR-7HK8N) in which 86 women with fibromyalgia were included, and written informed consent was obtained from them. The patients were allocated into four groups: LDN + tDCS (n = 21), LDN + tDCS Sham (n = 22), placebo + tDCS (n = 22), and placebo+tDCS Sham (n = 21). The LDN or placebo (p.o.) intervention lasted 26 days; in the last five sessions, tDCS was applied (sham or active, 20 min, 2 mA). The following categories were assessed: sociodemographic, Visual Analog Pain Scale (VAS), Pain Catastrophizing Scale (PCS), State-Trait Anxiety Inventory (STAI), Fibromyalgia Impact Questionnaire (FIQ), Beck Depression Inventory (BDI-II), Profile of Chronic Pain Scale (PCP:S), Pain Pressure Threshold (PPT), and Conditioned Pain Modulation (CPM). Blood samples were collected to analyze BDNF serum levels. Results At baseline, no significant difference was found regarding all measurements. VAS pain was significantly reduced in the LDN + tDCS (p = 0.010), LDN + tDCS Sham (p= 0.001), and placebo+tDCS Sham (p= 0.009) groups. In the PCP:S, the LDN+tDCS group showed reduced pain frequency and intensity (p= 0.001), effect of pain on activities (p= 0.014) and emotions (p= 0.008). Depressive symptoms reduced after all active interventions (p > 0.001). Conclusion Combined LDN+tDCS has possible benefits in reducing pain frequency and intensity; however, a placebo effect was observed in pain using VAS, and further studies should be performed to analyze the possible association.

Abstract Background The mortality rate of Brazilian people with haemophilia (PwH) is decreasing, but the relative incidence of deaths associated with cardiovascular disease (CVD) is increasing. Objectives We aimed to describe the CVD risk score of PwH according to Pooled Cohort Equations Risk (PCER) Calculator tool and its treatment recommendations. We also compared the PCER estimates with the respective Framingham Risk Score (FRS). Methods This cross-sectional study included male PwH ≥ 40 years treated at the Comprehensive Haemophilia Treatment Centre of Pernambuco (Recife/Brazil). PwH with a previous CVD event or a low-density lipid cholesterol ≥ 5.0 mmol/L were excluded. Interviews, medical file reviews, and blood tests were performed. The PCER tool was used to estimate the CVD risk and compare it with the respective FRS. A p-value < 0.05 was accepted as statistically significant. Results Thirty PwH were included. Median age was 51.5 [interquartile range-IQR; 46.0-59.5] years. The prevalence of obesity, systemic arterial hypertension, diabetes mellitus, hypertriglyceridaemia, hypercholesterolaemia, and hypoHDLaemia were 20%, 67%, 24%, 14%, 47%, and 23%, respectively. The median PCER score was 6.9% [IQR; 3.1-13.2], with 50% having a high risk (PCER ≥ 7.5%). Statin use was suggested for 54% of PwH. Blood pressure was poorly controlled in 47% of PwH. The agreement between PCER and FRS was 80% (κ = 0.60; p = 0.001). Conclusions Half of the male people with haemophilia aged 40 years or older had a 10-year high risk of developing CVD with strong recommendations to improve control of dyslipidaemia and blood pressure.

Resumo Fundamento A taxa de mortalidade de pessoas com hemofilia (PCH) no Brasil está diminuindo, mas a incidência relativa de mortes associadas a doenças cardiovasculares (DCV) tem aumentado. Objetivos Nosso objetivo foi descrever o escore de risco de DCV de PCHs de acordo com a ferramenta Pooled Cohort Equations Risk (PCER) Calculator e suas recomendações de tratamento. Além disso, foram comparadas as estimativas da PCER com o respectivo escore de risco de Framingham (FRS). Métodos Este estudo transversal incluiu PCHs do sexo masculino, com idade igual ou superior a 40 anos, tratados no Centro de Tratamento Integral de Hemofilia de Pernambuco (Recife/Brasil). PCHs com um evento cardiovascular prévio ou colesterol lipídico de baixa densidade ≥ 5,0 mmol/L foram excluídas. Entrevistas, revisões de prontuários médicos e exames de sangue foram realizados. A ferramenta PCER foi utilizada para estimar o risco de DCV e compará-lo com o respectivo FRS. Um valor de p < 0,05 foi aceito como estatisticamente significativo. Resultados Trinta PCHs foram incluídas. A idade mediana foi de 51,5 [intervalo interquartil-IIQ; 46,0-59,5] anos. A prevalência de obesidade, hipertensão arterial sistêmica, diabetes mellitus, hipertrigliceridemia, hipercolesterolemia e hipoHDLemia foi de 20%, 67%, 24%, 14%, 47% e 23%, respectivamente. O escore mediano da PCER foi de 6,9% [IIQ; 3,1-13,2], com 50% de alto risco (PCER ≥ 7,5%). O uso de estatina foi sugerido para 54% das PCHs. A pressão arterial estava mal controlada em 47% das PCHs. A concordância entre PCER e FRS foi de 80% (κ = 0,60; p = 0,001). Conclusões Metade dos homens com hemofilia, com 40 anos de idade ou mais, teve um alto risco de desenvolver DCV em 10 anos, com fortes recomendações para melhorar o controle da dislipidemia e da pressão arterial.

ABSTRACT Objective: To establish the implementation of nursing diagnoses and care for the spiritual dimension of people with cancer. Method: Action research in a university hospital in the north-east of Brazil. Nine nurses and thirteen nursing technicians from the Onco-hematology and Bone Marrow Transplant Unit of this hospital took part. Data collection took place in four phases and involved the talking map technique, pedagogical workshops and a logbook. The groups’ speeches were coded using Maxqda software, subjected to Braun and Clarke’s thematic analysis and interpreted in the light of Paulo Freire’s constructs. Results: Phase 1 sought to apprehend the participants’ prior knowledge on the subject; in phase 2, proposals emerged for spiritual care organized in the Nursing Process; in phase 3, the diagnoses and care plan for the spiritual dimension for clinical practice were contemplated; and in phase 4, through the final evaluation, it was possible to see the transformations that occurred in the nursing team’s practice with the proposed implementation. Conclusion: The educational actions provided significant learning for the nursing team and the implementation of diagnoses and nursing care for the spiritual dimension of people with cancer.

Abstract Objective: to analyze the association between previous Chikungunya infection and depressive symptoms among healthcare workers. Methods: a cross-sectional study with a probabilistic sample of healthcare workers in primary and medium-complexity care settings in a municipality in the state of Bahia, Brazil. We used the rapid test DPP-ZDC-IgM/IgG to identify recent (IgM) or previous (IgG) Chikungunya virus infection, and the Patient Health Questionnaire-PHQ-9 to assess depressive symptoms. We applied regression with robust variance to estimate prevalence ratios and 95% confidence intervals. Results: 392 workers participated, 83.2% female. The frequency of Chikungunya virus infection was 8.9%. The prevalence of depressive symptoms was 22.7%. In the adjusted analysis, Chikungunya infection was positively associated with depressive symptoms (PR=2.00; 95%CI: 1.29; 3.07). Stratified analyses indicated a stronger association among males (PR=7.57; 95%CI: 1.15; 50.06) compared with females (PR=1.68; 95%CI: 1.03; 2.74). Discussion: the findings support the hypothesis of a positive association between Chikungunya and depressive symptoms. Physiopathological mechanisms resulting from viral action, as well as emotional, behavioral, and psychosocial factors associated with the disease, may explain the findings. We reiterate the importance of providing mental health care to healthcare workers.

Resumo Objetivo: analisar a associação entre infecção prévia por Chikungunya e sintomas depressivos em trabalhadores da saúde. Métodos: estudo transversal com amostra probabilística de trabalhadores atuantes na atenção primária e na média complexidade de um município do estado da Bahia, Brasil. Utilizou-se o teste rápido DPP-ZDC-IgM/IgG para identificar infecção recente (IgM) ou prévia (IgG) pelo vírus Chikungunya. O Patient Health Questionnaire-PHQ-9 foi usado para avaliar sintomas depressivos. Regressão de Poisson com variância robusta foi usada para estimar razões de prevalência e intervalos de confiança 95%. Resultados: participaram da pesquisa 392 trabalhadores, sendo 83,2% do sexo feminino. A frequência de infecção pelo vírus Chikungunya foi de 8,9%. A prevalência de sintomas depressivos foi de 22,7%. Na análise ajustada, a infecção por Chikungunya associou-se positivamente aos sintomas depressivos (RP=2,00; IC95%:1,29;3,07). As análises estratificadas apontaram associação de maior magnitude no sexo masculino (RP=7,57;1,15;50,06), em comparação ao feminino (RP=1,68;1,03;2,74). Conclusão: os achados corroboram a hipótese de associação positiva entre Chikungunya e sintomas depressivos. Mecanismos fisiopatológicos decorrentes de ação viral, bem como fatores emocionais, comportamentais e psicossociais associados à doença podem explicar os achados. Reitera-se a importância do cuidado em saúde mental para os trabalhadores da saúde.

Resumen Objetivos: Identificar las alteraciones histopatológicas en órganos de ratas Wistar para evaluar los efectos tóxicos del uso del Extracto de Hoja Cruda de Annona muricata (AMRLE) solo o en asociación con DMBA. Configuración y diseño: Se utilizaron sesenta ratas hembras Wistar, se separaron en grupos y se trataron con una dosis única de 65 mg/kg de DMBA y/o con 50, 100 y 200 mg/kg de AMRLE. Se utilizaron tinciones de hematoxilina-eosina (HE) y azul de metileno al 1% en el análisis histopatológico y la cuantificación de criptas aberrantes (CA) y focus de criptas aberrantes (FCA). En el análisis estadístico se utilizaron las pruebas de Fischer y Kruskal Wallis. Resultados: La administración de 65 mg/kg de DMBA y/o 50, 100 y 200 mg/kg de AMRLE no influyó en el desarrollo del peso. Se observaron algunas alteraciones histopatológicas (esteatosis hepática; focus inflamatórios en el hígado, riñón y pulmón; hiperplasia, ectasia en epitelio de la glándula mamaria e hiperplasia linfoide pulmonar) y el desarrollo de CA y FCA en el colon intestinal en todos los grupos, excepto en el grupo control negativo, sin diferencias estadísticas entre los grupos analizados. Conclusiones: Las alteraciones histopatológicas y la formación de CA y FCA no mostraron diferencias estadísticamente significativas entre los grupos analizados. Sin embargo, aunque AMRLE tiene efectos antioxidantes debido a la presencia de componentes fenólicos, aún existe la formación de algunos procesos patológicos que pueden estar relacionados con la acción tóxica aislada del DMBA y/o asociados con otros componentes de AMRLE, ya que estos cambios no fueron observados en el grupo control negativo.

Abstract Aims: To identify the histopathological alterations in organs of Wistar rats to evaluate toxic effects of use of Annonamuricata Raw Leaf Extract (AMRLE) alone or in association with DMBA. Settings and Design: Sixty female Wistar rats were used, separated into groups and treated with a single dose of 65 mg/kg of DMBA and/or with 50; 100 and 200 mg/kg of AMRLE. Hematoxylin-Eosin (HE) and 1% methylene blue stains were used in the histopathological analysis and quantification of Aberrant Crypts (ACs) and Aberrant Crypt Focus (ACF). Fischer and Kruskal Wallis tests were used in the statistical analysis. Results: The administration of 65 mg/kg of DMBA and/or 50, 100 and 200 mg/kg of AMRLE did not influence weight development. Some histopathological alterations (hepatic steatosis; inflammatory foci in the liver, kidney and lung; pulmonary lymphoid hyperplasia, ectasia and hyperplasia in mammary gland epithelium) and the development of ACs and ACF in the intestinal colon were observed in all groups, except in the group negative control, with no statistical difference between analysed groups. Conclusions: Histopathological alterations and the formation of ACs and ACF did not show a statistically significant difference between the groups analysed. However, although AMRLE has antioxidant effects due to the presence of phenolic components, there was still the formation of some pathological processes that may be related to the isolated toxic action of DMBA and/or associated with other components of AMRLE, since these changes were not seen in the negative control group.

ABSTRACT Objective To analyze data from children who were previously healthy and presented with post-varicella arterial ischemic stroke upon arrival when admitted to the emergency room, with focus on the clinical/laboratory aspects, and neurocognitive performance after four-year follow-up. Methods Seven children presenting with arterial ischemic stroke after varicella were evaluated at pediatric emergency services in the city of São Paulo (SP), Brazil. Ischemic stroke was determined by magnetic resonance imaging/magnetic resonance angiography in a topography compatible with the areas supplied by the middle cerebral or internal carotid arteries. IgG-class antibodies against varicella zoster virus and varicella-zoster virus DNA by polymerase chain reaction in cerebrospinal fluid were tested. Patients with prothrombotic conditions were excluded. The Pediatric Stroke Outcome Measure was applied upon admission and 4-years after the stroke. Results All patients (age range: 1.3 to 4 years) included presented chickenpox 5.1 (±3.5) months before. All patients had analysis of anti-varicella-zoster-virus-IgG in cerebrospinal fluid, but only three (43%) had a positive result. Of the patients 43% had no vascular lesions identified in magnetic resonance angiography. All patients showed improvement in their sequela scores. After 4 years, five patients displayed good evolution in the Pediatric Stroke Outcome Measure, and only one patient presented with a score of 2 in the sensorimotor and cognition areas. No recurrence of arterial ischemic stroke was observed. Conclusion We reinforced the non-progressive course of post-varicella arterial ischemic stroke after 4-year follow-up. The presence of varicella-zoster-virus-DNA detected by polymerase chain reaction, and/or intrathecal IgG antibody against varicella zoster virus, and angiopathy location in magnetic resonance angiography were not determining for the diagnosis. Invasive tests, with low sensitivity, should be well considered in the diagnosis of post-varicella arterial ischemic stroke.

Abstract INTRODUCTION Improved recovery protocols were implemented in surgical specialties over the last decade, which decreased anesthetic and surgical stress and the incidence of perioperative complications. However, these recovery protocols were introduced more slowly for cardiac surgeries. The most frequent complications in cardiac surgery are related to patient clinical status and the characteristics of the surgical procedures involved, which are becoming more varied and complex every day. The first version of the enhanced recovery program for cardiac surgery was published in 2019, but its recommendations were based on only a few studies, and scant research has evaluated its implementation. Randomized and controlled clinical trials for these protocols are scarce, so research that summarizes the results of studies with other methodological designs are useful in demonstrating their benefits in cardiovascular surgery services in Cuba and in other limited-resource settings. OBJECTIVE Estimate the effectiveness of improved recovery protocols in the perioperative evolution of patients undergoing cardiac surgery.

Abstract Objective: To investigate the association between birth weight and excess weight among students aged 6–14 years, adjusted for life course confounding factors. Methods: Cross-sectional study with 6–14-year-old schoolchildren in 2010; 795 school children from two public schools. In addition, a sub-sample was selected using a case-cohort study approach. Sociodemographic, breastfeeding, food introduction, previous weight gain, family history, current clinical and behavioral variables as well as maternal variables related to pregnancy, were collected. Multivariable weighted logistic regression was used to evaluate the association between birth weight and overweight. All prevalent cases of overweight (n = 160) were selected to compose the case group and a random sub-sample of all students participating in the study (n = 276 students, of whom 88 were cases) were the control group. Results: An unadjusted 6% increase in the excess weight prevalence ratio (p-value = 0.004) was found for each 100 g increase in birth weight. With adjustment for age, sex and behavioral variables (models 1 and 2), the association of birth weight with excess weight was positive and statistically significant, but it was no longer significant in the final model (model 3) when clinical variables were considered. Conclusions: Although some of the secondary associations were statistically significant, we could not identify a significant association between birthweight and excess weight in adolescents.

ABSTRACT Objective: Multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease (COVID-19) is a rare and challenging diagnosis requiring early treatment. The diagnostic criteria involve clinical, laboratory, and complementary tests. This review aims to draw pediatrician attention to this diagnosis, suggesting early treatment strategies, and proposing a pediatric emergency care flowchart. Sources: The PubMed/MEDLINE/WHO COVID-19 databases were reviewed for original and review articles, systematic reviews, meta-analyses, case series, and recommendations from medical societies and health organizations published through July 3, 2020. The reference lists of the selected articles were manually searched to identify any additional articles. Summary of the findings: COVID-19 infection is less severe in children than in adults, but can present as MIS-C, even in patients without comorbidities. There is evidence of an exacerbated inflammatory response with potential systemic injury, and it may present with aspects similar to those of Kawasaki disease, toxic shock syndrome, and macrophage activation syndrome. MIS-C can develop weeks after COVID-19 infection, suggesting an immunomediated cause. The most frequent clinical manifestations include fever, gastrointestinal symptoms, rash, mucous membrane changes, and cardiac dysfunction. Elevated inflammatory markers, lymphopenia, and coagulopathy are common laboratory findings. Supportive treatment and early immunomodulation can control the intense inflammatory response and reduce complications and mortality. Conclusions: MIS-C associated with COVID-19 is serious, rare, and potentially fatal. The emergency department pediatrician must recognize and treat it early using immunomodulatory strategies to reduce systemic injury. Further studies are needed to identify the disease pathogenesis and establish the most appropriate treatment.

Resumo Fundamento: Principal causa de morte em todo o mundo, as doenças cardiovasculares (DCV) e sua prevalência nos médicos cardiologistas são pouco conhecidas. Objetivos: Descrever os hábitos de vida e os fatores de risco cardiovascular e verificar a prevalência de diagnóstico, conhecimento e controle dos fatores de risco cardiovasculares (FRCV) de médicos cardiologistas associados e especialistas pela Sociedade Brasileira de Cardiologia. Métodos: Estudo multicêntrico nacional transversal que avaliou cardiologistas brasileiros por meio de questionário sobre hábitos de vida, doenças preexistentes, medicações em uso, medidas antropométricas, pressão arterial e dosagens de glicose e lípideos sanguíneos. Resultados: Foram avaliados 555 cardiologistas, 67,9% do sexo masculino, média de idade de 47,2±11,7 anos. A maioria era não tabagista (88,7%), fisicamente ativa (77,1%), consumia bebida alcóolica (78,2%), com circunferência abdominal normal (51,7%) e excesso de peso (56,1%). As prevalências de hipertensão arterial sistêmica (HAS), diabetes mellitus (DM) e dislipidemia (DLP) foram de 32,4%, 5,9% e 49,7%, respectivamente e, destes, apenas 57,2%, 45,5% e 49,6% sabiam ter as doenças. Conclusões: Os cardiologistas brasileiros participantes do estudo apresentaram prevalências significativas de HAS, DM e DLP, mas apenas a metade dos participantes sabia ser portador dessas condições e, entre eles, as taxas de controle eram baixas para HAS e DLP, apesar de os cardiologistas serem profissionais detentores de conhecimento diferenciado sobre esses FRCV. Os achados representam um alerta para a abordagem dos FRCV em cardiologistas brasileiros e estimulam a realização de estudos futuros.

Abstract Background: A major cause of death worldwide, cardiovascular diseases and their prevalence in cardiologists are little known. Objectives: To describe life habits and cardiovascular risk factors (CVRF) and to investigate the prevalence of diagnosis, awareness, and control of these CVRF among cardiologists members affiliated to and specialists from the Brazilian Society of Cardiology. Methods: National multicenter cross-sectional study to assess Brazilian cardiologists using a questionnaire on life habits, preexisting diseases, current medications, anthropometric measurements, blood pressure, and levels of glucose and lipids. Results: A total of 555 cardiologists were evaluated, of which 67.9% were male, with a mean age of 47.2±11.7 years. Most were non-smoker (88.7%) and physically active (77.1%), consumed alcohol (78.2%), had normal weight circumference (51.7%), and were overweight (56.1%). The prevalence of systemic arterial hypertension (SAH), diabetes mellitus (DM), and dyslipidemia (DLP) were 32.4%, 5.9%, and 49.7%, respectively, of which only 57.2%, 45.5%, and 49.6%, respectively, were aware of the diseases. Conclusions: The Brazilian cardiologists participating in the study had a high prevalence of SAH, DM and DLP, but only a half of participants were aware of these conditions and, among these, the rates of controlled disease were low for SAH and DLP, although cardiologists are professionals with great knowledge about these CVRF. These findings represent a warning sign for the approach of CVRF in Brazilian cardiologists and encourage the conduction of future studies.
