Adequação do consumo de ácidos graxos entre pacientes em prevenção cardiovascular secundária / Adequacy of Fatty Acids Consumption Among Individuals in Secondary Cardiovascular Prevention

FUNDAMENTO: A adesão à uma alimentação adequada em macronutrientes é fundamental para a prevenção secundária de doenças cardiovasculares. OBJETIVO: Avaliar a prevalência de adesão às recomendações de consumo de ácidos graxos para prevenção e tratamento de doenças cardiovasculares, e estimar se a presença de determinados fatores de risco cardiovascular estaria associada à adesão. MÉTODOS: Estudo transversal com os dados de linha de base de 2358 participantes do estudo "Brazilian Cardioprotective Nutritional Program Trial". Dados de consumo alimentar, e fatores de risco cardiovascular foram avaliados. Foi considerada, de acordo com a Sociedade Brasileira de Cardiologia, uma ingestão adequada de ácidos graxos poli-insaturados (AGPI) ≥10% do consumo total de energia diária, para ácidos graxos monoinsaturados (AGM), 20% e para ácidos graxos saturados (AGS), <7%. Na análise estatística foi considerando nível de significância de 5%. RESULTADOS: Nenhum participante aderiu a todas as recomendações de forma simultânea e mais da metade (1482 [62,9%]) não aderiu a nenhuma recomendação. A adesão exclusivamente à recomendação de AGS foi a mais prevalente, sendo cumprida por 659 (28%) dos participantes, seguida da adesão exclusivamente à recomendação de AGP (178 [7,6%]) e de AGM (5 [0,2%]). Não houve associação entre o número de comorbidades e a adesão às recomendações nutricionais (p =0,269). Os participantes da região Nordeste do país apresentaram maior proporção de adesão às recomendações para consumo de AGS (38,42%), e menor para ingestão de AGPI (3,52%) (p <0,001) em comparação às demais. CONCLUSÕES: Na amostra avaliada, evidenciou-se baixa adesão às recomendações nutricionais para consumo de ácidos graxos.

Therapeutic Adherence According to the Morisky Scale in Patients with Hypertension

Abstract Background In view of the high prevalence of hypertension and the importance of adequate drug therapy in the prevention of complications, it is necessary to know the adherence to drug treatment in this population. Objective To verify adherence to antihypertensive drug treatment in Brazilian patients with hypertension using the Morisky-Green Test (MGT), relating it with demographic data. Methods Prospective, observational, multicenter, national registry study, with 2,578 hypertensive patients participating in study I, the Brazilian Cardiovascular Registry of Arterial Hypertension (I-RBH), recruited in the five regions of Brazil. The analyses carried out on the data were descriptive statistics, qui-square tests, ANOVA, and logistic regression, adopting 5% as the significance level for the tests. Results The research shows that 56.13% of patients in the sample were female; 56.71% were elderly (≥ 65 years); 55.86% were White; 52.37% were from the Southeast Region; and 59.74% were non-adherent. Logistic regression showed an independent relationship between patients' age, ethnicity, and region with medication adherence. Conclusion Adherence to treatment is the key to reducing high rates of cardiovascular complications. The study brings a successful outcome in the relationship between the factors ethnicity, age, and region of patients with hypertension and medication adherence. To this end, it is necessary to understand these factors, considering systematic evaluation in the care of patients with hypertension and other chronic non-communicable diseases. This study is a significant contribution to multidisciplinary teams, as it highlights which risk factors interfere with medication adherence, incorporating better strategies in health education.

Cardiorespiratory optimal point in post-COVID-19 patients: a cross-sectional study

ABSTRACT The varied clinical presentations of SARS-CoV-2 infection have raised concerns about long-term consequences, especially "long-COVID" or "post-COVID-19 syndrome." In this context, the cardiorespiratory optimal point (COP) within the Cardiopulmonary Exercise Test (CPET) emerges as a crucial metric for evaluating functional capacities and detecting cardiovascular and pulmonary anomalies post-COVID-19. This study aimed to assess COP values among post-COVID-19 patients and categorized them based on the initial severity of their disease. In this cross-sectional study conducted in the Northeast Brazil, 80 patients (26 females and 54 males) previously infected with SARS-CoV-2 underwent CPET. We clinically stratified patients into mild, moderate, or severe COVID-19 categories and assessed COP values and other cardiorespiratory metrics. We found differences in the predicted COP between patients with mild and severe COVID-19 (p=0.042). Additionally, patients with moderate and severe COVID-19 record had an average COP value exceeding 22. Other parameters, including respiratory exchange ratio, heart rate, and oxygen uptake efficiency slope, did not differ across the groups. Patients with a history of severe COVID-19 showed altered COP values, suggesting potential discrepancies in cardiovascular and respiratory system integration. The outcomes emphasize the importance of continuous monitoring and assessment of the cardiorespiratory domain for post-COVID-19 patients. Further research is needed to understand the relationship between elevated COP in post-severe COVID-19 and its long-term prognostic implications.

Religiosity and Spirituality: The Relationship Between Psychosocial Factors and Cardiovascular Health

Abstract Background: Religiosity and Spirituality (R/S), despite being different entities, are multidimensional constructs, whose influence on cardiovascular health has been increasingly studied in recent decades. Objectives: To discriminate patients into subgroups according to R/S levels, in order to compare them regarding the distribution of cardiovascular comorbidities and clinical events. Methods: This is an observational, cross-sectional, analytical study. Two R/S scales were applied to a sample of patients seen at cardiology outpatient clinics. A cluster analysis was used to discriminate individuals into subgroups regarding R/S levels, which were subsequently compared regarding the frequencies of clinical variables related to cardiovascular health. A significance level of 5% was set for the statistical tests. Results: The sample included 237 patients with a mean age of 60.8 years (±10.7), of which 132 were female (55.7%). Cluster analysis (C) distinguished two groups: C1, with lower levels of R/S, and C2, with higher levels of R/S (p<0.001). C2 had a lower frequency of alcohol consumption (29.5% vs. 76.0%; p<0.001), smoking (12.9% vs. 51.0%; p<0.001), systemic arterial hypertension (SAH — 65.5% vs. 82.3%; p=0.005), dyslipidemia (58.3% vs. 77.1%; p=0.003), chronic coronary syndrome (36.7% vs. 58.3%; p=0.001), and prior cardiovascular events (15.8% vs. 36.5%; p<0.001) when compared to C1. There was also a higher frequency of females in C2 (82.0% vs. 17.7%; p<0.001). Conclusions: A better cardiovascular morbidity profile was observed in the group of patients with higher R/S levels, suggesting a probable positive relationship between R/S and cardiovascular health.

Non-Targeted Self-Measured Blood Pressure and Hypertension Control in Public and Private Health Systems in Brazil

Abstract Background: It is estimated that more than 30% of the Brazilian population has systemic arterial hypertension (SAH), and mostly as an uncontrolled disease. The most recent Brazilian Guideline of Hypertension recommends the practice of self-measurement of blood pressure (BP) as one of the strategies for a better control of SAH, but there is no consensus about the efficiency of this tool. Objective: To assess the control of SAH and the practice of non-targeted self-measured BP (SMBP) among hypertensive users of the Unified Health System (SUS) and the Supplementary Network (SN). Methods: This is a cross-sectional, observational, analytical study, with a stratified probability sample. One thousand volunteers were investigated, being 500 from SUS and 500 from the SN. Uni and multivariate analyses were performed considering a 5% significance level. Results: Patients from SUS presented inferior sociodemographic data (schooling, social status) in relation to those of the SN (p < 0.001), and showed lower control of SAH (p = 0.014), as well as more visits to the emergency room in the past year due to hypertension (p = 0.002), and fewer regular appointments with the cardiologist (p = 0.004). SMBP was equally present in both assessed groups (p = 0.567), even though users of the SN have been more advised to not conduct such a practice (p = 0.002). SMBP (p < 0.001) was an independent factor for uncontrolled SAH both in SUS (OR = 3.424) and in the SN (OR = 3.474). Conclusion: Patients in SUS presented lower SAH control. The practice of SMBP, mostly practiced with an uncalibrated digital device, was equally present in both groups and became an independent factor of uncontrolled SAH.

Resposta Exagerada da Pressão Arterial Sistólica ao Exercício e Isquemia Miocárdica à Ecocardiografia sob Estresse Físico / Exaggerated Systolic Blood Pressure Increase with Exercise and Myocardial Ischemia on Exercise Stress Echocardiography

Resumo Fundamento A associação entre resposta exagerada da pressão arterial sistólica ao exercício (REPASE) e isquemia miocárdica é controversa e pouco estudada em indivíduos com síndrome coronariana crônica estabelecida ou suspeita. Objetivo Verificar a relação entre isquemia miocárdica e REPASE em indivíduos submetidos à ecocardiografia sob estresse físico (EEF). Métodos Trata-se de estudo transversal com 14.367 indivíduos submetidos à EEF, de janeiro de 2000 a janeiro de 2022, divididos em dois grupos: G1 - composto por pacientes cuja pressão sistólica de pico apresentou incremento ≥ 90 mmHg (valor correspondente ao percentil 95 da população estudada) -, e G2 - formado por indivíduos que não apresentaram resposta hipertensiva exagerada. Os grupos foram comparados mediante os testes t de Student e qui-quadrado. Foram considerados significativos os valores de p < 0,05. Realizou-se, também, regressão logística para identificação de fatores de risco independentes para isquemia miocárdica, REPASE, queixa de precordialgia típica prévia ao exame e angina durante o teste. Resultados Dos 14.367 pacientes, 1.500 (10,4%) desenvolveram REPASE e 7.471 (52,0%) eram do sexo feminino. Os percentuais de queixa prévia de precordialgia típica, angina durante o teste e isquemia miocárdica dos pacientes com REPASE foram de 5,8%, 2,4% e 18,1% contra 7,4%, 3,9% e 24,2%, em indivíduos sem REPASE, respectivamente (p = 0,021, p = 0,004, p < 0,001). Na análise multivariada, a REPASE foi associada, independentemente, a uma menor probabilidade de isquemia miocárdica (odds ratio: 0,73; intervalo de confiança de 95%: 0,58 a 0,93; p = 0,009). Conclusão O incremento exagerado da pressão arterial sistólica durante a EEF pode ser um marcador de exclusão de isquemia miocárdica.

Abstract Background The association between exaggerated systolic blood pressure response to exercise (ESBPRE) and myocardial ischemia is controversial and little studied in patients with established or suspected chronic coronary syndrome. Objective To verify the relationship between myocardial ischemia and ESBPRE in patients undergoing exercise stress echocardiography (ESE). Methods This is a cross-sectional study with 14,367 patients undergoing ESE, from January 2000 to January 2022, divided into the following 2 groups: G1, composed of patients whose peak systolic pressure increased ≥ 90 mmHg (value corresponding to the 95th percentile of the study population), and G2, patients who did not demonstrate an exaggerated hypertensive response. The groups were compared using Student's t and chi-square tests. P values < 0.05 were considered significant. Logistic regression was also performed to identify independent risk factors for myocardial ischemia, ESBPRE, complaints of typical chest pain prior to the exam, and angina during the test. Results Of the 14,367 patients, 1,500 (10.4%) developed ESBPRE, and 7,471 (52.0%) were female. The percentages of previous complaints of typical chest pain, angina during the test, and myocardial ischemia in patients with ESBPRE were 5.8%, 2.4% and 18.1%, compared to 7.4%, 3.9%, and 24.2%, in patients without ESBPRE, respectively (p = 0.021,p = 0.004, p < 0.001). In multivariate analysis, ESBPRE was independently associated with a lower probability of myocardial ischemia (odds ratio: 0.73; 95% confidence interval: 0.58 to 0.93; p = 0.009). Conclusion Exaggerated increase in systolic blood pressure during ESE may be a marker for excluding myocardial ischemia.

Subclinical Systolic Dysfunction during Chemotherapy for Breast Cancer

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.

Infecção pelo sars-cov-2 e disfunção autonômica ­ labilidade pressórica na covid-19 / Sars-cov-2 infection and autonomic dysfunction - pressure liability at covid-19

Homem de 53 anos, hipertenso e portador de bronquite, admitido em um serviço de urgência no dia 15 de dezembro de 2020 devido sintomas gripais, febre e cefaleia iniciados há oito dias. Após constatação de acometimento pulmonar importante mediante tomografia computadorizada (TC) de tórax, sugestivo de infecção pelo vírus SARS-CoV2, o paciente foi internado em unidade de terapia intensiva. Foi intubado no décimo dia de internação, e, dois dias após, evoluiu com labilidade pressórica importante, recorrendo ao uso de noradrenalina e nitroprussiato, além de outros anti-hipertensivos, conforme a necessidade. O quadro predominante foi a hipertensão arterial sistêmica, manifestada principalmente com a mudança de decúbito, sendo o maior valor pressórico registrado de 240x90 mmHg. A disautonomia também se manifestou por ausência de dejeções, sudorese excessiva e espasmos musculares. A frequência cardíaca se manteve estável e dentro dos parâmetros de normalidade.A partir do trigésimo dia de internação, observou-se melhora progressiva do quadro e reestabelecimento da homeostase. Obteve alta após 59 dias de internação, sem sequelas significativas. A explicação mais razoável para o caso é o aumento da resistência vascular periférica, por ação da angiotensina II, associada à supressão do sistema parassimpático, o que explica, também, a incompetência do barorreflexo para compensação da frequência cardíaca. Adicionalmente, o paciente estava em uso de carvedilol. Este caso enfatiza o desafio diagnóstico precoce da disautonomia em pacientes críticos, devido a carência de ferramentas adequadas para uso na prática cotidiana. A estimulação vagal pode constituir opção terapêutica eficaz, mas carece de mais estudos

A 53-year-old male, hypertensive and with bronchitis, was admitted to the emergency department on December 15, 2020 due to flu-like symptoms, fever and headache that started eight days ago. After finding significant lung involvement by chest computed tomography (CT) suggestive of SARS-CoV2 virus infection, the patient was admitted to the intensive care unit. He was intubated on the tenth day of hospitalization, and, 2 days later, he evolved with significant pressure lability, using norepinephrine and nitroprusside, in addition to other antihypertensive drugs, as needed. The predominant state was hypertension, expressed mainly when there is interference from the patient's position in bed. The highest pressure value recorded was 240x90 mmHg. Dysautonomy was also manifested by the absence of stools, excessive sweating and muscle spasms. Heart rate remains stable and within normal limits. From the thirtieth day of hospitalization onwards, there was an evolution with progressive improvement and restoration of homeostasis. He was discharged after 59 days of hospitalization, without sequelae. The most reasonable explanation for the case is the increase in peripheral vascular resistance, due to the action of angiotensin II, associated with the suppression of the parasympathetic system, which also explains the incompetence of the baroreflex to compensate the heart rate. Additionally, the patient was using carvedilol. This case emphasizes the importance of tools that early identify dysautonomy, prepare the team. Vagal stimulation can be an effective therapeutic option, but further studies are needed

Influence of Factors Affecting Quality of Life on in-Hospital Cardiovascular Events of Patients with Acute Myocardial Infarction with and without ST-segment Elevation

Abstract Background Acute myocardial infarction (AMI), with and without ST-segment elevation (STEMI and NSTEMI, respectively), is the principal cause of cardiovascular morbidity and mortality in Brazil and around the world. Modifiable risk factors (RF) and quality of life (QOL) may correlate with the type of AMI. Objective To evaluate the influence of QOL and RF on the type of AMI and in-hospital cardiovascular events in STEMI and NSTEMI patients. Methods This was an observational, cross-sectional study. Patients with AMI attending four referral hospitals (three private and one public) for cardiovascular disease treatment were assessed for QOL using the Brazilian version of the 36-item short form survey. A p < 0.05 was considered statistically significant. Results We evaluated 480 volunteers; 51% were treated in one of the private hospitals. In total, 55.6% presented with STEMI, and 44.4% with NSTEMI. Patients from the public hospital were 8.56 times more likely to have STEMI compared to those from the private hospitals. There was a higher prevalence of smokers in STEMI (p < 0.028) patients. QOL was not associated with the type of AMI. A negative patient perception of the physical health and pain domains was observed. Although a significant difference between the physical and the mental health domains was not observed, individual domains were correlated with some in-hospital outcomes. Conclusion There was a higher prevalence of smokers among individuals with STEMI. Domains of QOL showed a statistically significant relationship with the occurrence of in-hospital cardiovascular events, with no difference between the types of AMI.

Disfunção diastólica precoce em pacientes com câncer de mama submetidas à quimioterapia / Early diastolic dysfunction in breast cancer patients undergoing chemotherapy

Fundamento: A quimioterapia para o câncer de mama está associada a complicações cardiovasculares graves, como a insuficiência cardíaca. A fração de ejeção do ventrículo esquerdo é o principal parâmetro para avaliar a função sistólica nessas pacientes. Todavia, a ocorrência de disfunção diastólica pode preceder à disfunção sistólica. Objetivos: Avaliar as funções diastólica e sistólica do ventrículo esquerdo de portadoras de câncer de mama em tratamento quimioterápico com antraciclinas. Métodos: Trata-se de estudo observacional, longitudinal, analítico e prospectivo. Estudaram-se 62 mulheres com câncer de mama, com idades de 21 a 75 anos, que realizaram ecocardiogramas basais e após 3 meses de tratamento. Avaliaram-se parâmetros de função diastólica, e as pacientes foram classificadas em disfunção diastólica tipos:1, 2 ou 3. Definiu-se a disfunção sistólica como fração de ejeção do ventrículo esquerdo ≤ 53%. Resultados: Decorridos 3 meses de tratamento, 35 pacientes (56,4%) apresentavam disfunção diastólica tipo 1, e apenas uma (1,6%) do tipo 2. A disfunção diastólica ocorreu em 26 pacientes já na etapa basal e surgiu em dez indivíduos no decurso do tratamento. Os parâmetros de função diastólica velocidade de onda E e relação E/A diminuíram significativamente (p < 0,05) com a quimioterapia, todavia, os demais não tiveram variação significativa. Apenas três pacientes apresentaram disfunção sistólica, porém verificou-se maior redução da fração de ejeção do ventrículo esquerdo no grupo que desenvolveu disfunção diastólica durante o tratamento comparativamente ao grupo que apresentava já disfunção diastólica no período basal (p = 0,04). Conclusão: A disfunção diastólica ocorre precocemente em portadoras de câncer de mama submetidas à quimioterapia. O surgimento de disfunção diastólica no decurso do tratamento se associa à redução significativa da fração de ejeção do ventrículo esquerdo. (AU)

Background: Chemotherapy for breast cancer is associated with serious cardiovascular complications such as heart failure. The left ventricular ejection fraction is the main parameter used to assess systolic function in these patients. However, the occurrence of diastolic dysfunction may precede that of systolic dysfunction. Objectives: To evaluate left ventricle diastolic and systolic functions in women with breast cancer undergoing chemotherapy using anthracyclines. Methods: This observational, longitudinal, analytical, and prospective study included 62 women with breast cancer aged 21­75 years old who underwent echocardiography at baseline and after three months of treatment. Diastolic function parameters were evaluated, and the patients were classified as diastolic dysfunction type 1, 2, or 3. Systolic dysfunction was defined as a left ventricular ejection fraction ≤ 53%. Results: After three months of treatment, 35 patients (56.4%) had type 1 diastolic dysfunction, while one (1.6%) had type 2. Diastolic dysfunction was identified in 26 patients at baseline and developed in 10 patients during treatment. Diastolic function parameters, E wave velocity, and E/A ratio decreased significantly (p < 0.05) with chemotherapy; however, the others showed no significant variations. Only three patients had systolic dysfunction, but there was a greater reduction in left ventricular ejection fraction in the group that developed diastolic dysfunction during treatment versus the group with diastolic dysfunction at baseline (p = 0.04). Conclusion: Diastolic dysfunction occurs early in women with breast cancer undergoing chemotherapy. Its onset during the course of treatment is associated with a significantly reduced left ventricular ejection fraction. (AU)

Ecoestresse físico na cardiomiopatia hipertrófica: como, quando e por quê? / Exercise stress echocardiography in hypertrophic cardiomyopathy: how, when and why?

Resumo Historicamente, o papel do ecocardiograma de estresse físico no manejo da cardiomiopatia hipertrófica tem sido negligenciado na prática clínica, de acordo com a análise das diretrizes do American College of Cardiology/ American Heart Association de 2002, que recomendavam cautela no uso dessa metodologia, em portadores de cardiomiopatia hipertrófica, devido ao risco de possível ocorrência tanto de arritmia cardíaca, como de colapso hemodinâmico no esforço. Atualmente, o estresse físico na cardiomiopatia hipertrófica integra a avaliação rotineira de pacientes sintomáticos com ou sem gradiente da via de saída do ventrículo esquerdo < 50 mmHg, em repouso. Para este grupo, é um método seguro e confiável para medir o gradiente da via de saída do ventrículo esquerdo durante o esforço e sólido diferenciador de pacientes com cardiomiopatia hipertrófica não obstrutivos (gradiente ausente, tanto em repouso quanto no esforço) daqueles com gradientes lábeis (gradiente ausente no repouso e presente no esforço). Portanto, na avaliação da cardiomiopatia hipertrófica, o estresse físico é igualmente útil na quantificação do grau de regurgitação mitral, nas alterações da contratilidade segmentar do ventrículo esquerdo e na avaliação da função diastólica do ventrículo esquerdo, diante do esforço, sendo capaz de predizer o futuro desenvolvimento de sintomas de insuficiência cardíaca. O método é também importante na determinação das diferentes estratégias de tratamento para cada paciente, desde a miomectomia cirúrgica ou a ablação septal alcoólica, para aqueles com gradiente lábil, com sintomas limitantes e refratários ao tratamento medicamentoso versus transplante cardíaco para aqueles sem gradiente.(AU)

Avaliação do Seguimento de um Ano dos Pacientes Incluídos no Registro Brasileiro de Síndromes Coronárias Agudas (ACCEPT) / One year follow-up Assessment of Patients Included in the Brazilian Registry of Acute Coronary Syndromes (ACCEPT)

Resumo Fundamento Existe carência de informações prospectivas sobre a evolução em um ano após uma síndrome coronária aguda (SCA) em uma grande amostra de pacientes brasileiros. Objetivos Avaliar a prescrição de terapias baseadas em evidência, a ocorrência de desfechos graves e os preditores para estes desfechos em um registro brasileiro multicêntrico de pacientes com SCA. Métodos O ACCEPT é um estudo observacional prospectivo que incluiu pacientes internados com diagnóstico de SCA em 47 hospitais brasileiros. Os pacientes foram seguidos por 1 ano e coletou-se dados sobre prescrição médica e ocorrência de eventos cardiovasculares maiores (mortalidade cardiovascular, reinfarto e acidente vascular encefálico - AVE). Valores de p < 0,05 foram considerados estatisticamente significantes. Resultados Um total de 5.047 pacientes foram incluídos neste registro, de agosto de 2010 até abril de 2014. Foi confirmado o diagnóstico de SCA em 4.782 pacientes (94,7%) e, dentre os 3 diagnósticos possíveis, o mais comum foi SCA com elevação do segmento ST (35,8%). A taxa de eventos cardiovasculares maiores foi de 13,6 % em 1 ano. A prescrição completa de terapias baseadas em evidência na admissão hospitalar foi de 62,1%. Idade, atendimento público, infarto agudo do miocárdio, AVE, insuficiência renal, diabetes e qualidade da terapia estiveram associados de forma independente à ocorrência de eventos cardiovasculares maiores. Conclusões No seguimento de 1 ano do registro ACCEPT, mais de 10% dos pacientes apresentaram eventos cardiovasculares maiores e esta taxa variou de acordo com a qualidade da terapia. Há necessidade da elaboração de estratégias para melhorar o uso de terapias baseadas em evidência no sentido de minimizar os eventos cardiovasculares na população brasileira. (Arq Bras Cardiol. 2020; 114(6):995-1003)

Abstract Background There is lack of prospective data on evolution within one year of acute coronary syndromes (ACS) in a representative population of Brazilian patients. Objectives To assess the prescription of evidence-based therapies, the incidence of severe outcomes and the predictors for these outcomes in a multicenter Brazilian registry of ACS patients. Methods The ACCEPT is a prospective observational study, which included patients hospitalized with a diagnostic of ACS in 47 Brazilian hospitals. The patients were followed for a 1 year and data were collected on the medical prescription and the occurrence of major cardiovascular events (cardiovascular mortality, reinfarction and cerebrovascular accident - CVA). Values of p < 0.05 were considered statistically significant. Results A total of 5,047 patients were included in this registry from August 2010 to April 2014. The diagnosis of ACS was confirmed in 4,782 patients (94.7%) and, among those, the most frequent diagnosis was ACS with ST segment elevation (35.8%). The rate of major cardiovascular events was 13.6 % within 1 year. Adherence to prescription of evidence-based therapy at admission was of 62.1%. Age, public service, acute myocardial infarction, CVA, renal failure, diabetes and quality of therapy were associated independently with the occurrence of major cardiovascular events. Conclusions During the one-year follow-up of the ACCEPT registry, more than 10% of the patients had major cardiovascular events and this rate ranged according with the quality of therapy. Strategies must be elaborated to improve the use of evidence-based therapies to minimize the cardiovascular events among the Brazilian population. (Arq Bras Cardiol. 2020; 114(6):995-1003)

Quality of Intra-Hospital Nutritional Counseling in Patients with STEMI in the Public and Private Health Networks of Sergipe: The VICTIM Register / Qualidade da Orientação Nutricional Intra-hospitalar em Pacientes com IAMcSST das Redes Pública e Privada de Saúde em Sergipe: Registro (VICTIM)

Abstract Background: Having appropriate dietary habits is part of the recommendations after ST-Elevation Myocardial Infarction (STEMI), however, the quality of intra-hospital nutritional counselling in the different health services has been minimally explored. Objective: To evaluate the quality of intra-hospital nutritional counselling among patients with STEMI in the public and private health systems in Sergipe. Methods: A cross-sectional, with data from the Via Crucis for the Treatment of Myocardial Infarction (VICTIM) Register, conducted from April to November of 2017, with individuals aged ≥ 18 years diagnosed with STEMI, in one public health service hospital and three private hospitals. The occurrence and quality of nutritional counselling were analyzed based on current guidelines and the administration of questionnaires. A significance level of 0.05 was adopted. Results: A total of 188 patients were analyzed; 80.3% were from the public health service facility. Among the interviewees, 57.6% of the public health service, and 70.3% of the private hospital patients received intra-hospital nutritional counselling (p = 0.191). The documentation of this practice, in medical records, was lower in the public service (2.6% vs. 37.8%, p < 0.001). A predominance of restrictive orientations was found in the public and private sectors, mainly regarding salt and fat, 52.3% and 70.3% respectively (p = 0.064). Patients from the private service were more counselling to introduce of cardioprotective foods, mainly fruit, vegetable/legume consumption (48.6% vs. 13.2%, p < 0.001). Among those who received counselling, nutritional knowledge was higher in the private sector (68.2% vs. 26.3%, p < 0.001). Conclusion: The intra-hospital nutritional counselling provided to patients with STEMI, in Sergipe, still presents poor quality in both services, especially in the public health system.

Resumo Fundamento: A adequação dos hábitos alimentares faz parte das recomendações pós-infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMcSST); contudo, tem sido pouco explorada a qualidade da orientação nutricional intra-hospitalar nos diferentes serviços de saúde. Objetivo: Avaliar a qualidade da orientação nutricional intra-hospitalar entre pacientes com IAMcSST nas redes de saúde pública e privada em Sergipe. Métodos: Estudo transversal, com dados do Registro Via Crucis para o Tratamento do Infarto do Miocárdio (VICTIM), realizado de abril a novembro de 2017 com indivíduos com idade ≥ 18 anos, diagnosticados com IAMcSST em um hospital público e três privados. Analisaram-se a ocorrência de orientação nutricional e a sua qualidade com base nas diretrizes atuais e por meio de aplicação de questionários, sendo adotado nível de significância de 0,05. Resultados: Foram avaliados 188 voluntários, sendo 80,3% do serviço público. Dentre os entrevistados, 57,6% da rede pública e 70,3% da privada receberam orientação nutricional intra-hospitalar (p = 0,191). O registro dessa prática em prontuário foi menor no serviço público (2,6% versus 37,8%; p < 0,001). Verificou-se o predomínio das orientações restritivas, sobretudo de sal e gorduras, 52,3% e 70,3% no público e no privado, respectivamente (p = 0,064). Quanto à inserção de alimentos cardioprotetores, pacientes da rede privada foram mais beneficiados, principalmente quanto ao consumo de frutas e verduras/legumes (48,6% versus 13,2%, p < 0,001). Entre aqueles que receberam orientação, o conhecimento nutricional foi maior no sistema privado (68,2% versus 26,3%, p < 0,001). Conclusão: A orientação nutricional intra-hospitalar para o IAMcSST em Sergipe apresenta baixa qualidade em ambos os serviços de saúde, sobretudo no público.

Readmission of Patients with Acute Coronary Syndrome and Determinants / Reinternação de Pacientes com Síndrome Coronariana Aguda e seus Determinantes

Abstract Background: Acute coronary syndrome (ACS) is responsible for high rates of hospital admission and readmission, which are associated with increased costs for the patient and the health system, and increased in-hospital mortality rates. Objective: To evaluate readmission in patients with ACS and its determinants. Methods: This was a retrospective cohort study of adult and elderly patients with ACS, readmitted to public and private referral cardiology hospitals within one year after the first hospitalization for ACS. The occurrence of readmissions, the time elapsed from the first to the second admission, and the use of medications at admission were collected from the medical records. Associations between categorical variables were evaluated by the chi-square test or the Fisher's exact test. Multiple logistic regression was used to evaluate predictors for readmissions. A p < 0.05 was set as statistically significant. Results: Readmission rate was 21.5% (n = 115) and mean time between admissions was 122.7 ± 112.1 days. The patients were mostly men (64.0%), mean age of 63.15 ± 12.3 years. Among readmitted patients, 7% had a prognosis of "death", and 68.7% were readmitted more than once within a one-year period. The main reasons of readmission were cardiovascular diseases including ACS. Private health care and the diagnosis of congestive heart failure were associated with multiple logistic regression. Conclusion: ACS was the main cause of readmission, with higher prevalence among users of supplemental health care. Readmissions were associated with previous diagnosis of congestive heart failure and the type of health care provided.

Resumo Fundamento: A síndrome coronariana aguda (SCA) é responsável por elevados números de admissões e readmissões hospitalares, os quais estão associados ao aumento dos custos para o paciente e para o sistema de saúde, bem como à elevação nas taxas de mortalidade hospitalar. Objetivo: Investigar a reinternação entre pacientes com SCA e seus determinantes. Métodos: Trata-se de uma coorte retrospectiva de pacientes de ambos os sexos, adultos e idosos, diagnosticados com SCA. Foram avaliados, a partir dos registros dos hospitais locais públicos e privados de referência em cardiologia, a ocorrência de reinternação em até 1 ano após internação por SCA, o tempo entre as admissões e o uso de medicamentos no momento da reinternação. As variáveis categóricas foram associadas por meio do teste qui-quadrado, ou pelo teste exato de Fisher. Regressão logística múltipla foi utilizada para avaliar as variáveis preditoras da reinternação. Adotou-se como critério de significância estatística um valor de p < 0,05. Resultados: A ocorrência de reinternações foi de 21,46% (n = 115), e o período médio entre as internações foi de 122,74 (DP 112,14) dias. Os pacientes avaliados eram, em sua maioria, do sexo masculino (64,0%), com média de idade de 63,15 anos (DP 12,26). Sete por cento apresentaram óbito como prognóstico da reinternação, e 68,7% tiveram mais de uma reinternação em 1 ano. As causas cardiovasculares, entre elas a recorrência da SCA, foram as mais prevalentes entre as reinternações hospitalares. A assistência privada e o diagnóstico de insuficiência cardíaca congestiva (ICC) foram associados a reinternação após a regressão logística múltipla. Conclusão: Conclui-se que a SCA foi a principal causa de reinternação, sendo mais prevalente entre os usuários da rede suplementar de saúde. As reinternações associaram-se ao diagnóstico prévio de ICC e ao tipo de assitência à saúde.

Disparities In The Use Of Drug-eluting Stents For Diabetic Patients With ST-elevation Acute Myocardial Infarction Assisted In the Public versus Private Network - VICTIM Register / Disparidades no Uso de Stents Farmacológicos para Pacientes Diabéticos com Infarto Agudo do Miocárdio com Supradesnivelamento do Segmento ST Assistidos na Rede Pública versus Privada - Registro VICTIM

Abstract Background: Primary angioplasty (PA) with placement of either bare metal or drug-eluting stents (DES) represents the main strategy in the treatment of ST-elevation myocardial infarction (STEMI). Diabetic patients, however, represent a special population in STEMI, with high rates of restenosis and unfavorable clinical outcomes, and with the use of DES, level of evidence A and indication class II, being indicated to reduce these damages. Objectives: To evaluate the DES rate of use in patients with STEMI and in the subgroup of diabetics assisted in the public versus private health network in Sergipe. Methods: This is a population-based, cross-sectional study with a quantitative approach using the data from the VICTIM Register. These were collected in the only four hospitals with capacity to perform PA in Sergipe, from December 2014 to March 2017. Results: A total of 707 patients diagnosed with STEMI were evaluated, of which 589 were attended at SUS and 118 at the private network. The use of DES in PA was lower in SUS compared to the private network in both the total sample (10.5% vs 82.4%, p<0.001) and in subgroup diabetic patients (8.7% vs 90.6%, p < 0.001), respectively. In all hypotheses tested, the level of significance was 5% (p < 0.05). Conclusions: The study reveals a disparity in the use of DES during the performance of PA between the public and private network, both in the total sample and the subgroup for diabetics, with lower rates for SUS users, demonstrating the challenges that need to be overcome in order to achieve quality improvements of the services provided.

Resumo Fundamento: A angioplastia primária (AP) com colocação de stent, seja ele convencional ou farmacológico, representa a principal estratégia no tratamento do infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Os pacientes diabéticos, entretanto, representam população especial no IAMCSST, com altas taxas de reestenose e desfechos clínicos desfavoráveis, devendo-se indicar o uso de stents farmacológicos (SF), nível de evidência A e classe de indicação II, para redução destes danos. Objetivo: Avaliar a taxa de uso de SF em pacientes com IAMCSST e no subgrupo dos diabéticos assistidos na rede pública versus privada de saúde em Sergipe. Métodos: Trata-se de um estudo populacional, transversal, com abordagem quantitativa, que utilizou os dados do Registro VICTIM. Estes foram coletados nos quatro únicos hospitais com capacidade para realizar AP em Sergipe, no período de dezembro de 2014 a março de 2017. Em todas as hipóteses testadas, o nível de significância adotado foi de 5% (p < 0,05). Resultados: Foram avaliados 707 pacientes diagnosticados com IAMCSST, dos quais 589 foram atendidos pelo SUS e 118 pela rede privada. O uso de SF na AP foi menor no SUS em comparação com a rede privada, tanto no total da amostra (10,5% vs 82,4%; p < 0,001) quanto no subgrupo dos pacientes diabéticos (8,7% vs 90,6%; p < 0,001), respectivamente. Conclusões: O estudo revela disparidade no uso de SF durante a realização de AP entre a rede pública e privada, tanto na amostra total quanto no subgrupo dos diabéticos, com menores taxas para usuários do SUS, demonstrando os desafios que necessitam ser vencidos para se atingir melhorias na qualidade dos serviços prestados.
