RESUMEN
BACKGROUND: The neurological manifestations in COVID-19 adversely impact acute illness and post-disease quality of life. Limited data exist regarding the association of neurological symptoms and comorbid individuals. OBJECTIVE: To assess neurological symptoms in hospitalized patients with acute COVID-19 and multicomorbidities. METHODS: Between June 2020 and July 2020, inpatients aged 18 or older, with laboratory-confirmed COVID-19, admitted to the Hospital São Paulo (Federal University of São Paulo), a tertiary referral center for high complexity cases, were questioned about neurological symptoms. The Composite Autonomic Symptom Score 31 (COMPASS-31) questionnaire was used. The data were analyzed as a whole and whether subjective olfactory dysfunction was present or not. RESULTS: The mean age of the sample was 55 ± 15.12 years, and 58 patients were male. The neurological symptoms were mostly xerostomia (71%), ageusia/hypogeusia (50%), orthostatic intolerance (49%), anosmia/hyposmia (44%), myalgia (31%), dizziness (24%), xerophthalmia (20%), impaired consciousness (18%), and headache (16%). Furthermore, 91% of the patients had a premorbidity. The 44 patients with subjective olfactory dysfunction were more likely to have hypertension, diabetes, weakness, shortness of breath, ageusia/hypogeusia, dizziness, orthostatic intolerance, and xerophthalmia. The COMPASS-31 score was higher than that of previously published controls (14.85 ± 12.06 vs. 8.9 ± 8.7). The frequency of orthostatic intolerance was 49% in sample and 63.6% in those with subjective olfactory dysfunction (2.9-fold higher risk compared to those without). CONCLUSION: A total of 80% of inpatients with multimorbidity and acute COVID-19 had neurological symptoms. Chemical sense and autonomic symptoms stood out. Orthostatic intolerance occurred in around two-thirds of the patients with anosmia/hyposmia. Hypertension and diabetes were common, mainly in those with anosmia/hyposmia.
ANTECEDENTES: As manifestações neurológicas na COVID-19 impactam adversamente na enfermidade aguda e na qualidade de vida após a doença. Dados limitados existem em relação a associação de sintomas neurológicos e indivíduos com comorbidades. OBJETIVO: Avaliar os sintomas neurológicos em pacientes de hospitalizados com COVID-19 aguda e múltiplas comorbidades. MéTODOS: Entre junho e julho de 2020, pacientes de hospitais com idade 18 anos ou acima e COVID-19 laboratorialmente confirmada, admitidos no Hospital São Paulo (Universidade Federal de São Paulo), um centro de referência terciário para casos de alta complexidade, foram perguntados sobre sintomas neurológicos. O questionário Pontuação composta de sintoma autonômico (COMPASS-31) foi usado. Os dados foram analisados no geral e se a disfunção olfatória subjetiva estava presente ou não. RESULTADOS: A média de idade da amostra foi 55 ± 15.12 anos. 58 pacientes eram homens. Os sintomas neurológicos foram principalmente xerostomia (71%), ageusia/hipogeusia (50%), intolerância ortostática (49%), anosmia/hiposmia (44%), mialgia (31%), tontura (24%), xeroftalmia (20%), comprometimento na consciência (18%) e cefaleia (16%). Além disso, 91% dos pacientes tinham uma pré-morbidade. Os 44 pacientes com disfunção olfatória tinham maior chance de ter hipertensão, diabetes, fraqueza, falta de ar, ageusia/hipogeusia, tontura, intolerância ortostática e xeroftalmia. A pontuação do COMPASS-31 foi maior do que a de controles previamente publicados (14,85 ± 12,06 vs. 8,9 ± 8,7). A frequência de intolerância ortostática foi 49% na amostra e 63,6% naqueles com disfunção olfatória subjetiva (risco 2.9 vezes maior comparado com os sem). CONCLUSãO: Um total de 80% dos pacientes hospitalizados com múltiplas morbidades e COVID-19 aguda tinham sintomas neurológicos. Os sintomas do sentido químico e autonômicos se destacaram. A intolerância ortostática ocorreu em cerca de dois terços dos pacientes com anosmia/hiposmia. A hipertensão e o diabetes foram comuns, principalmente naqueles com anosmia/hiposmia.

BACKGROUND: A Nationwide Initiative to Improve Cardiology Quality: The Best Practice in Cardiology Program in Brazil ACEI/ARB: angiotensin-converting enzyme inhibitor/angiotensin receptor blocker; LVEF: left ventricular ejection fraction; LVSD: left ventricular systolic dysfunction; AF: atrial fibrillation; PT/INR: prothrombin time/international normalized ratio. BACKGROUND: Despite significant progress in improving the quality of cardiovascular care, persistent gaps remain in terms of inconsistent adherence to guideline recommendations. OBJECTIVE: This study evaluates the effects of implementing a quality improvement program adapted from the American Heart Association's Get with the Guidelines™ initiative on adherence to guideline-directed medical therapy for acute coronary syndrome (ACS), atrial fibrillation (AF), and heart failure (HF). METHODS: We examined demographics, quality measures, and short-term outcomes in patients hospitalized with ACS, AF, and HF enrolled in the Best Practice in Cardiology (BPC) Program from 2016 to 2022. RESULTS: This study included 12,167 patients in 19 hospitals in Brazil. Mean age was 62.5 [53.8-71] y/o; 61.1% were male, 68.7% had hypertension, 32.0% diabetes mellitus, and 24.1% had dyslipidemia. Composite score had a sustainable performance in the period from baseline to the last quarter: 65.8±36.2% to 73± 31.2% for AF (p=0.024), 81.0± 23.6% to 89.9 ± 19.3% for HF (p<0.001), and from 88.0 ± 19.1 to 91.2 ±14.9 for ACS (p<0.001). CONCLUSIONS: The BPC program is a quality improvement program in Brazil in which real-time data, obtained using cardiology guideline metrics, were implemented in a quality improvement program resulting in an overall sustained improvement in AF, HF, and ACS management.

BACKGROUND: Atrial fibrillation is a public health problem associated with a fivefold increased risk of stroke or death. Analyzing costs is important when introducing new therapies and must be reconsidered in special situations, such as the novel coronavirus pandemic of 2020. OBJECTIVE: This study aimed to evaluate the costs related to anticoagulant therapy in a one-year period, and the quality of life of atrial fibrillation patients treated in a public university hospital. METHODS: Patient costs were those related to the anticoagulation and calculated by the average monthly costs of warfarin or direct oral anticoagulants (DOACs). Patient non-medical costs (eg., food and transportation) were calculated from data obtained by questionnaires. The Brazilian SF-6D was used to measure the quality of life. P-values < 0.05 were considered statistically significant. RESULTS: The study population consisted of 90 patients, 45 in each arm (warfarin vs direct oral anticoagulants). Costs were 20% higher in the DOAC group ($55,532.62 vs $46,385.88), and mainly related to drug price ($23,497.16 vs $1,903.27). Hospital costs were higher in the warfarin group ($31,088.41 vs $24,604.74) and related to outpatient visits. Additionally, non-medical costs were almost twice higher in the warfarin group ($13,394.20 vs $7,430.72). Equivalence of price between the two drugs could be achieved by a 39% reduction in the price of DOACs. There were no significant group differences regarding quality of life. CONCLUSIONS: Total costs were higher in the group of patients taking DOACs than those taking warfarin. However, a nearly 40% reduction in the price of DOACs could make it feasible to incorporate these drugs into the Brazilian public health system.
FUNDAMENTO: A fibrilação atrial é um problema de saúde pública associado com um risco cinco vezes maior de acidente vascular cerebral e mortalidade. A análise de custos é importante para a introdução de novas terapias, e deve ser reconsiderada em situações especiais, tais como a pandemia do coronavírus em 2020. OBJETIVO: Avaliar os custos (em um período de um ano) relacionados à terapia anticoagulante e a qualidade de vida de pacientes com fibrilação atrial tratados em um hospital público universitário. MÉTODOS: Os custos do paciente foram aqueles relacionados à anticoagulação e calculados pela média de custos mensais da varfarina ou de anticoagulantes orais diretos (DOACs). As despesas não médicas, como alimentação e transporte, foram calculadas a partir de dados obtidos de questionários. O questionário brasileiro SF-6D foi usado para medir a qualidade de vida. Valores p<0,05 foram considerados estatisticamente significativos. RESULTADOS: A população do estudo consistiu em 90 pacientes, 45 em cada braço (varfarina vs. DOACs). Os custos foram 20% mais altos no grupo dos DOACs (US$55 532,62 vs. US$46 385,88), e principalmente relacionados ao preço dos medicamentos (US$23 497,16 vs. US$1903,27). Os custos hospitalares foram mais altos no grupo da varfarina (US$31 088,41 vs $24 604,74), e relacionados às visitas ao ambulatório. Ainda, as despesas não médicas foram duas vezes maiores no grupo varfarina ($13 394,20 vs $7 430,72). A equivalência de preço entre os dois medicamentos seria alcançada por uma redução de 39% no preço dos DOACs. Não foram observadas diferenças quanto à qualidade de vida. CONCLUSÕES: Os custos totais foram mais altos no grupo de pacientes tratados com DOACs que no grupo da varfarina. No entanto, uma redução de cerca de 40% no preço dos DOACs tornaria viável a incorporação desses medicamentos no sistema de saúde público brasileiro.

BACKGROUND: Primary percutaneous coronary intervention is considered the "gold standard" for coronary reperfusion. However, when not available, the drug-invasive strategy is an alternative method and the electrocardiogram (ECG) has been used to identify reperfusion success. OBJECTIVES: Our study aimed to assess ST-Segment changes in post-thrombolysis and their power to predict recanalization and using the angiographic scores TIMI-flow and Myocardial Blush Grade (MBG) as an ideal reperfusion criterion. METHODS: 2,215 patients with ST-Segment Elevation Myocardial Infarction (STEMI) undergoing fibrinolysis [(Tenecteplase)-TNK] and referred to coronary angiography within 24 h post-fibrinolysis or immediately referred to rescue therapy were studied. The ECG was performed pre- and 60 min-post-TNK. The patients were categorized into 2 groups: those with ideal reperfusion (TIMI-3 and MBG-3) and those with inadequate reperfusion (TIMI and MBG <3). The ECG reperfusion criterion was defined by the reduction of the ST-Segment >50%. A p-value <0.05 was considered for the analyses, with bicaudal tests. RESULTS: The ECG reperfusion criterion showed a positive predictive value of 56%; negative predictive value of 66%; sensitivity of 79%; and specificity of 40%. There was a weak positive correlation between ST-Segment reduction and ideal reperfusion angiographic data (r = 0.21; p <0.001) and low diagnostic accuracy, with an AUC of 0.60 (95%CI: 0.57-0.62). CONCLUSION: The ST-Segment reduction was not able to accurately identify patients with adequate angiographic reperfusion. Therefore, even patients with apparently successful reperfusion should be referred to angiography soon, to ensure adequate macro and microvascular coronary flow.
FUNDAMENTO: A intervenção coronária percutânea primária é considerada o "padrão-ouro" para reperfusão coronária. Entretanto, quando não disponível, a estratégia fármaco-invasiva é método alternativo, e o eletrocardiograma (ECG) tem sido utilizado para identificar sucesso na reperfusão. OBJETIVOS: Nosso estudo teve como objetivo examinar alterações no segmento-ST pós-lise e seu poder de prever a recanalização, usando os escores angiográficos TIMI e blush miocárdio (MBG) como critério de reperfusão ideal. MÉTODOS: Foram estudados 2.215 pacientes com infarto agudo do miocárdio com supra-ST submetidos à fibrinólise [(Tenecteplase)-TNK] e encaminhados para angiografia coronária em até 24 h pós-fibrinólise ou imediatamente encaminhados à terapia de resgate. O ECG foi realizado pré-TNK e 60 min-pós. Os pacientes foram categorizados em dois grupos: aqueles com reperfusão ideal (TIMI-3 e MBG-3) e aqueles com reperfusão inadequada (fluxo TIMI <3). Foi definido o critério de reperfusão do ECG pela redução do segmento ST >50%. Consideramos p-valor <0,05 para as análises, com testes bicaudais. RESULTADOS: O critério de reperfusão pelo ECG apresentou valor preditivo positivo de 56%; valor preditivo negativo de 66%; sensibilidade de 79%; e especificidade de 40%. Houve fraca correlação positiva entre a redução do segmento-ST e os dados angiográficos de reperfusão ideal (r = 0,21; p <0,001) e baixa precisão diagnóstica, com AUC de 0,60 (IC-95%; 0,57-0,62). CONCLUSÃO: Em nossos resultados, a redução do segmento-ST não conseguiu identificar com precisão os pacientes com reperfusão angiográfica apropriada. Portanto, mesmo pacientes com reperfusão aparentemente bem-sucedida devem ser encaminhados à angiografia brevemente, a fim de garantir fluxo coronário macro e microvascular adequados.

BACKGROUND: In clinical practice, there is evidence of failure to prescribe evidence-based therapies for patients at high cardiovascular risk. However, in Brazil, data on 1-year outcomes of these patients remain insufficient. OBJECTIVES: To describe the use of evidence-based therapies and the occurrence of major cardiovascular outcomes and their major predictors in a 12-month follow-up of a Brazilian multicenter registry of patients at high cardiovascular risk. METHODS: This prospective observational study documented the outpatient clinical practice of managing patients over 45 years of age and of high cardiovascular risk in both primary and secondary prevention. Patients were followed-up for 1 year, and the prescription of evidence-based therapies and the occurrence of major cardiovascular events (myocardial infarction, stroke, cardiac arrest, and cardiovascular death) were assessed. P-values < 0.05 were considered statistically significant. RESULTS: From July 2010 to August 2014, a total of 5076 individuals were enrolled in 48 centers, 91% of the 4975 eligible patients were followed-up in cardiology centers, and 68.6% were in secondary prevention. At 1 year, the concomitant use of antiplatelet agents, statins, and angiotensin-converting enzyme inhibitors reduced from 28.3% to 24.2% (p < 0.001). Major cardiovascular event rate was 5.46%, and the identified predictors were age, patients in secondary prevention, and diabetic nephropathy. CONCLUSIONS: In this large national registry of patients at high cardiovascular risk, risk predictors similar to those of international registries were identified, but medical prescription adherence to evidence-based therapies was inferior and significantly worsened at 1 year. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0).
FUNDAMENTO: Na prática clínica, há evidências de falhas na prescrição de terapias baseadas em evidências para pacientes de alto risco cardiovascular. Entretanto, no Brasil, ainda são insuficientes os dados sobre a evolução ao longo de 1 ano desses pacientes. OBJETIVOS: Descrição no acompanhamento de 12 meses da utilização de terapias baseadas em evidência e da ocorrência de desfechos cardiovasculares maiores e seus principais preditores em um registro brasileiro multicêntrico de pacientes de alto risco cardiovascular. MÉTODOS: Estudo observacional prospectivo que documentou a prática clínica ambulatorial de indivíduos acima de 45 anos e de alto risco cardiovascular tanto em prevenção primária como secundária. Os pacientes foram seguidos por 1 ano e avaliou-se a prescrição de terapias baseadas em evidência e a ocorrência de eventos cardiovasculares maiores (infarto agudo do miocárdio [IAM], acidente vascular cerebral [AVC], parada cardíaca e mortalidade por causa cardiovascular). Valores de p < 0,05 foram considerados estatisticamente significantes. RESULTADOS: De julho de 2010 até agosto de 2014, 5.076 indivíduos foram incluídos em 48 centros, sendo 91% dos 4.975 pacientes elegíveis acompanhados em centros de cardiologia e 68,6% em prevenção secundária. Em 1 ano, o uso concomitante de antiplaquetários, estatinas e inibidores da enzima conversora de angiotensina (IECA) reduziu de 28,3% para 24,2% (valor de p < 0,001). A taxa de eventos cardiovasculares maiores foi de 5,46%, e os preditores identificados foram: idade, pacientes em prevenção secundária e nefropatia diabética. CONCLUSÕES: Neste grande registro nacional de pacientes de alto risco cardiovascular, foram identificados preditores de risco semelhantes aos registros internacionais, porém a adesão da prescrição médica a terapias baseadas em evidência esteve abaixo dos dados da literatura internacional e apresentou piora significativa em 1 ano.

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).

Background There are substantial opportunities to improve the quality of cardiovascular care in developing countries through the implementation of a quality program. Objective To evaluate the effect of a Best Practice in Cardiology (BPC) program on performance measures and patient outcomes related to heart failure, atrial fibrillation and acute coronary syndromes in a subset of Brazilian public hospitals. Methods The Boas Práticas em Cardiologia (BPC) program was adapted from the American Heart Association's (AHA) Get With The Guidelines (GWTG) Program for use in Brazil. The program is being started simultaneously in three care domains (acute coronary syndrome, atrial fibrillation and heart failure), which is an approach that has never been tested within the GWTG. There are six axes of interventions borrowed from knowledge translation literature that will address local barriers identified through structured interviews and regular audit and feedback meetings. The intervention is planned to include at least 10 hospitals and 1,500 patients per heart condition. The primary endpoint includes the rates of overall adherence to care measures recommended by the guidelines. Secondary endpoints include the effect of the program on length of stay, overall and specific mortality, readmission rates, quality of life, patients' health perception and patients' adherence to prescribed interventions. Results It is expected that participating hospitals will improve and sustain their overall adherence rates to evidence-based recommendations and patient outcomes. This is the first such cardiovascular quality improvement (QI) program in South America and will provide important information on how successful programs from developed countries like the United States can be adapted to meet the needs of countries with developing economies like Brazil. Also, a successful program will give valuable information for the development of QI programs in other developing countries. Conclusions This real-world study provides information for assessing and increasing adherence to cardiology guidelines in Brazil, as well as improvements in care processes.

OBJECTIVES: To study the evolution of lesions in conduction system using invasive electrophysiological studies (EPS), the impact of these alterations on cardiovascular events (CVE), and the frequency of these events in chronic chagasic patients. METHODS: Prospective study, initiated in 1979 with clinical follow-up until 2000, with the participation of 28 chronic chagasic patients that were 18 to 65 years old, with bundle branch and/or atrioventricular blocks. The patients were submitted to two EPS with a minimum interval of four years between the studies in order to assess five electrophysiologists parameters that were correlated with CVE. A 24-hour Holter and echocardiogram were performed. RESULTS: The average follow-up time after the first EPS was 154.5 months while the interval between EPS was 107.5 months. Ages ranged from 25 to 65 years. Twenty seven patients presented complete right bundle branch block associated with a left anterior hemiblock. The echocardiogram showed alteration in twelve patients. During the 24-hour Holter and ventricular stimulation, only one patient presented sustained ventricular tachycardia (SVT). Nine presented CVE during the study and only the HV interval > or = 70 ms presented a significant statistical relationship with CVE. CONCLUSIONS: a) The chronic form of Chagas disease presents different progressive abnormality percentages for the electrophysiological variables and WP alterations are the most common. b) Among the electrophysiological findings, only the HV interval > or = 70 ms was associated with CVE. c) The incidence of CVE was 31.1% during the average follow-up period of 154.5 months.

OBJECTIVE: Compare hemodynamic and angiographic patterns, as well as atherosclerotic lesion morphology, in diabetic and non-diabetic females with unstable angina or non-ST-segment-elevation myocardial infarction (UA/NSTEMI). METHODS: Two interventional cardiologists determined the presence of severe atherosclerotic lesion, defined as those > or = 70%; plaque morphology, according to the American Heart Association classification; collateral circulation; plus ventricular and aortic pressures. Ejection fraction was calculated by angiography or echocardiography. RESULTS: During eight and a half years, 645 coronary angiographies were performed in women with UA/NSTEMI. In the present study, 593 female patients were assessed (215 diabetic--36%). This group differed from the non-diabetic in the following aspects: older age (61 +/- 10.6 x 58.1 +/- 11.4), higher prevalence of postmenopausal women and lower prevalence of the smoking habit. Severe three-vessel disease was significantly more frequent in diabetic patients (28% x 10%), as well as totally occluded vessels: 51 (23%) x 54 (14.3%), p < 0.005. Additionally, ejection fraction < 50% was more common in diabetic patients. CONCLUSION: These findings confirm the diffuse pattern of atherosclerotic disease in diabetic patients, as well a greater deterioration of ventricular function, which may be associated to the poorer prognosis seen in this population both in the short- and long-term.

Resumo Fundamento A intervenção coronária percutânea primária é considerada o "padrão-ouro" para reperfusão coronária. Entretanto, quando não disponível, a estratégia fármaco-invasiva é método alternativo, e o eletrocardiograma (ECG) tem sido utilizado para identificar sucesso na reperfusão. Objetivos Nosso estudo teve como objetivo examinar alterações no segmento-ST pós-lise e seu poder de prever a recanalização, usando os escores angiográficos TIMI e blush miocárdio (MBG) como critério de reperfusão ideal. Métodos Foram estudados 2.215 pacientes com infarto agudo do miocárdio com supra-ST submetidos à fibrinólise [(Tenecteplase)-TNK] e encaminhados para angiografia coronária em até 24 h pós-fibrinólise ou imediatamente encaminhados à terapia de resgate. O ECG foi realizado pré-TNK e 60 min-pós. Os pacientes foram categorizados em dois grupos: aqueles com reperfusão ideal (TIMI-3 e MBG-3) e aqueles com reperfusão inadequada (fluxo TIMI <3). Foi definido o critério de reperfusão do ECG pela redução do segmento ST >50%. Consideramos p-valor <0,05 para as análises, com testes bicaudais. Resultados O critério de reperfusão pelo ECG apresentou valor preditivo positivo de 56%; valor preditivo negativo de 66%; sensibilidade de 79%; e especificidade de 40%. Houve fraca correlação positiva entre a redução do segmento-ST e os dados angiográficos de reperfusão ideal (r = 0,21; p <0,001) e baixa precisão diagnóstica, com AUC de 0,60 (IC-95%; 0,57-0,62). Conclusão Em nossos resultados, a redução do segmento-ST não conseguiu identificar com precisão os pacientes com reperfusão angiográfica apropriada. Portanto, mesmo pacientes com reperfusão aparentemente bem-sucedida devem ser encaminhados à angiografia brevemente, a fim de garantir fluxo coronário macro e microvascular adequados.
Abstract Background Primary percutaneous coronary intervention is considered the "gold standard" for coronary reperfusion. However, when not available, the drug-invasive strategy is an alternative method and the electrocardiogram (ECG) has been used to identify reperfusion success. Objectives Our study aimed to assess ST-Segment changes in post-thrombolysis and their power to predict recanalization and using the angiographic scores TIMI-flow and Myocardial Blush Grade (MBG) as an ideal reperfusion criterion. Methods 2,215 patients with ST-Segment Elevation Myocardial Infarction (STEMI) undergoing fibrinolysis [(Tenecteplase)-TNK] and referred to coronary angiography within 24 h post-fibrinolysis or immediately referred to rescue therapy were studied. The ECG was performed pre- and 60 min-post-TNK. The patients were categorized into 2 groups: those with ideal reperfusion (TIMI-3 and MBG-3) and those with inadequate reperfusion (TIMI and MBG <3). The ECG reperfusion criterion was defined by the reduction of the ST-Segment >50%. A p-value <0.05 was considered for the analyses, with bicaudal tests. Results The ECG reperfusion criterion showed a positive predictive value of 56%; negative predictive value of 66%; sensitivity of 79%; and specificity of 40%. There was a weak positive correlation between ST-Segment reduction and ideal reperfusion angiographic data (r = 0.21; p <0.001) and low diagnostic accuracy, with an AUC of 0.60 (95%CI: 0.57-0.62). Conclusion The ST-Segment reduction was not able to accurately identify patients with adequate angiographic reperfusion. Therefore, even patients with apparently successful reperfusion should be referred to angiography soon, to ensure adequate macro and microvascular coronary flow.

Resumo Fundamento Na prática clínica, há evidências de falhas na prescrição de terapias baseadas em evidências para pacientes de alto risco cardiovascular. Entretanto, no Brasil, ainda são insuficientes os dados sobre a evolução ao longo de 1 ano desses pacientes. Objetivos Descrição no acompanhamento de 12 meses da utilização de terapias baseadas em evidência e da ocorrência de desfechos cardiovasculares maiores e seus principais preditores em um registro brasileiro multicêntrico de pacientes de alto risco cardiovascular. Métodos Estudo observacional prospectivo que documentou a prática clínica ambulatorial de indivíduos acima de 45 anos e de alto risco cardiovascular tanto em prevenção primária como secundária. Os pacientes foram seguidos por 1 ano e avaliou-se a prescrição de terapias baseadas em evidência e a ocorrência de eventos cardiovasculares maiores (infarto agudo do miocárdio [IAM], acidente vascular cerebral [AVC], parada cardíaca e mortalidade por causa cardiovascular). Valores de p < 0,05 foram considerados estatisticamente significantes. Resultados De julho de 2010 até agosto de 2014, 5.076 indivíduos foram incluídos em 48 centros, sendo 91% dos 4.975 pacientes elegíveis acompanhados em centros de cardiologia e 68,6% em prevenção secundária. Em 1 ano, o uso concomitante de antiplaquetários, estatinas e inibidores da enzima conversora de angiotensina (IECA) reduziu de 28,3% para 24,2% (valor de p < 0,001). A taxa de eventos cardiovasculares maiores foi de 5,46%, e os preditores identificados foram: idade, pacientes em prevenção secundária e nefropatia diabética. Conclusões Neste grande registro nacional de pacientes de alto risco cardiovascular, foram identificados preditores de risco semelhantes aos registros internacionais, porém a adesão da prescrição médica a terapias baseadas em evidência esteve abaixo dos dados da literatura internacional e apresentou piora significativa em 1 ano.

Abstract Background In clinical practice, there is evidence of failure to prescribe evidence-based therapies for patients at high cardiovascular risk. However, in Brazil, data on 1-year outcomes of these patients remain insufficient. Objectives To describe the use of evidence-based therapies and the occurrence of major cardiovascular outcomes and their major predictors in a 12-month follow-up of a Brazilian multicenter registry of patients at high cardiovascular risk. Methods This prospective observational study documented the outpatient clinical practice of managing patients over 45 years of age and of high cardiovascular risk in both primary and secondary prevention. Patients were followed-up for 1 year, and the prescription of evidence-based therapies and the occurrence of major cardiovascular events (myocardial infarction, stroke, cardiac arrest, and cardiovascular death) were assessed. P-values < 0.05 were considered statistically significant. Results From July 2010 to August 2014, a total of 5076 individuals were enrolled in 48 centers, 91% of the 4975 eligible patients were followed-up in cardiology centers, and 68.6% were in secondary prevention. At 1 year, the concomitant use of antiplatelet agents, statins, and angiotensin-converting enzyme inhibitors reduced from 28.3% to 24.2% (p < 0.001). Major cardiovascular event rate was 5.46%, and the identified predictors were age, patients in secondary prevention, and diabetic nephropathy. Conclusions In this large national registry of patients at high cardiovascular risk, risk predictors similar to those of international registries were identified, but medical prescription adherence to evidence-based therapies was inferior and significantly worsened at 1 year.

OBJECTIVE: To assess the effects of the relief of the mitral stenosis by percutaneous ballon valvotomy in the function of the left atrial appendage. METHODS: Twelve patients with symptomatic mitral stenosis, in sinus rhythm, were studied. They were submitted to the transesophageal echocardiogram before and after effective percutaneous ballon valvotomy. Concerning the left atrial appendage, the peak flow velocities and the respective integral of the anterograde and retrograde flow, in addition to the ejection fraction calculated through the planimetry of the area of that structure, were analyzed at the pulsatile Doppler. RESULTS: There was a significant increase of the anterograde flow velocity of the left atrial appendage after percutaneous ballon valvotomy (pre: mean of 0.30 m/s; post: mean of 0.47 m/s; p<0.05) and their respective integrals. The same happened with the retrograde flow velocity (pre: mean of 0.35 m/s, post: mean of 0.53 m/s; p<0.05). There was a tendency of increase of the ejection fraction of the left atrial appendage after the procedure (pre: mean of 20%, post: mean of 31%; p=0.08). CONCLUSION: The effective opening of the stenosed mitral orifice resulting from the percutaneous ballon valvotomy determined an improvement of the flow pattern of the left atrial appendage, which can potentially contribute for the reduction of the embolic risk.

Abstract New translational concepts on cellular and tissue substrate of cardiac arrhythmias have been responsible for the development of non-pharmacological interventions, with important achievements compared to the conventional approach with antiarrhythmic drugs. In addition, the increasing knowledge of anatomical and electrophysiological studies, sophisticated mapping methods, special catheters, and controlled clinical trials have favored the progression of ablation of tachyarrhythmias, particularly of ventricular tachyarrhythmias and atrial fibrillation.

BACKGROUND: Left atrial volume (LAV) is a predictor of prognosis in patients with heart failure. OBJECTIVE: We aimed to evaluate the determinants of LAV in patients with dilated cardiomyopathy (DCM). METHODS: Ninety patients with DCM and left ventricular (LV) ejection fraction ≤ 0.50 were included. LAV was measured with real-time three-dimensional echocardiography (eco3D). The variables evaluated were heart rate, systolic blood pressure, LV end-diastolic volume and end-systolic volume and ejection fraction (eco3D), mitral inflow E wave, tissue Doppler e' wave, E/e' ratio, intraventricular dyssynchrony, 3D dyssynchrony index and mitral regurgitation vena contracta. Pearson's coefficient was used to identify the correlation of the LAV with the assessed variables. A multiple linear regression model was developed that included LAV as the dependent variable and the variables correlated with it as the predictive variables. RESULTS: Mean age was 52 ± 11 years-old, LV ejection fraction: 31.5 ± 8.0% (16-50%) and LAV: 39.2±15.7 ml/m2. The variables that correlated with the LAV were LV end-diastolic volume (r = 0.38; p < 0.01), LV end-systolic volume (r = 0.43; p < 0.001), LV ejection fraction (r = -0.36; p < 0.01), E wave (r = 0.50; p < 0.01), E/e' ratio (r = 0.51; p < 0.01) and mitral regurgitation (r = 0.53; p < 0.01). A multivariate analysis identified the E/e' ratio (p = 0.02) and mitral regurgitation (p = 0.02) as the only independent variables associated with LAV increase. CONCLUSION: The LAV is independently determined by LV filling pressures (E/e' ratio) and mitral regurgitation in DCM.

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.

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)
