RESUMO

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

RESUMO

AIMS: Patients with advanced heart failure (HF) with reduced left ventricular ejection fraction (HFrEF) and concurrent coronavirus disease 2019 (COVID-19) might have a higher risk of severe events. METHODS AND RESULTS: We retrospectively studied 16 patients with advanced HFrEF who developed COVID-19 between 1 March and 29 May 2020. Follow-up lasted until 30 September. Ten patients previously hospitalized with decompensated HFrEF were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during hospitalization. Six patients undergoing ambulatory care at initiation of COVID-19 symptoms were hospitalized because of advanced HFrEF. All patients who experienced worsening of HFrEF due to COVID-19 required higher doses or introduction of additional inotropic drugs or intra-aortic balloon pump in the intensive care unit. The mean intravenous dobutamine dose before SARS-CoV-2 infection in previously hospitalized patients (n = 10) and the median (inter-quartile range) peak intravenous dobutamine dose during SARS-CoV-2 infection in all patients (n = 16) were 2 (0-7) µg/kg/min and 20 (14-20) (P < 0.001), respectively. During follow-up, 56% underwent heart transplantation (n = 2) or died (n = 7). Four patients died during hospitalization from mixed shock consequent to severe acute respiratory syndrome with inflammatory storm syndrome associated with septic and cardiogenic shock during COVID-19. After COVID-19 recovery, two patients died from mixed septic and cardiogenic shock and one from sustained ventricular tachycardia and cardiogenic shock. Five patients were discharged from hospital to ambulatory care. Four were awaiting heart transplantation. CONCLUSION: Worsening of advanced HF by COVID-19 is associated with high mortality. This report highlights the importance of preventing COVID-19 in patients with advanced HF.

RESUMO

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital's electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

RESUMO

There is limited evidence in the literature regarding the administration of clopidogrel to acute coronary syndrome (ACS) in patients over 75 years of age. Most studies excluded this age group, making the subject controversial due to the increased risk of bleeding in this population. Objective: This is a retrospective, unicentric, and observational study aimed at assessing whether the administration of clopidogrel loading dose increases bleeding rates in patients over 75 years of age. Methods: Patients were divided into two groups: group I: 75 mg of clopidogrel; group II: 300-to 600-mg loading dose of clopidogrel. A total of 174 patients (129 in group I and 45 in group II) were included between May 2010 and May 2015. Statistical analysis: The primary outcome was bleeding (major and/or minor). The secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). The comparison between groups was performed through Q-square and T-test. The multivariate analysis was performed by logistic regression, being considered significant p < 0.05. Results: Comparisons between groups I and II showed differences in the prevalence of diabetes (46.5% vs. 24.4%, p = 0.01), arterial hypertension (90.7% vs. 75, p = 0.01), dyslipidemia (62% vs. 42.2%, p = 0.021), ST segment elevation (11.6% vs. 26.6%, p = 0.016) and coronary intervention percutaneous (16.5% vs. 62.2%, p < 0.0001), respectively. In the multivariate analysis, significant differences were observed between groups I and II in relation to the occurrence of bleeding (8.5% vs. 20%, OR = 0.173, 95% CI: 0.049 - 0.614, p = 0.007). Conclusion: A loading dose of 300 mg or more of clopidogrel

RESUMO

OBJECTIVE: Cardiac myxoma is a benign neoplasm, which corresponds to the most common primary heart tumour, responsible for about 50% of the cases. In general, 75-80% of myxomas are located in the left atrium, 18% in the right atrium, and more rarely in the ventricles or multicentric. Right atrial myxoma, in particular, can obstruct the tricuspid valve, causing symptoms of right heart failure, peripheral oedema, hepatic congestion, and syncope. Systemic embolization occurs in 30% of cases, by either tumour fragmentation or total tumour detachment. CONCLUSIONS: In the present report, we present a case of a symptomatic patient, who showed a large right intra-atrial lesion, with consequent superior vena cava syndrome, and then underwent surgical resection at admission.

RESUMO O mixoma cardíaco é uma neoplasia benigna, que corresponde ao tumor primário mais comum do coração, responsável por cerca de 50% dos casos. De modo geral, 75 a 80% dos mixomas estão localizados no átrio esquerdo, 18% no átrio direito, e mais raramente, nos ventrículos ou multicêntricos. O mixoma atrial direito, em particular, pode obstruir a válvula tricúspide, causando sintomas de insuficiência cardíaca direita, edema periférico, congestão hepática e síncope. A embolização sistêmica ocorre em 30% dos casos, quer pela fragmentação do tumor ou pelo desprendimento total do mesmo. No presente relato, apresentamos um caso de uma paciente sintomática, que evidenciou grande lesão intra-atrial direita, com consequente síndrome da veia cava superior, sendo, então, submetida a ressecção cirúrgica na internação.

RESUMO

Abstract Background: Gender-related differences have been reported in patients with acute coronary syndrome. The description of this comparative finding in a Brazilian registry has not yet been documented. Objective: To compare male vs. female patients regarding the baseline characteristics, coronary findings, treatment and in-hospital and long-term prognosis. Methods: This is a retrospective, multicenter and observational study that included 3,745 patients (2,437 males and 1,308 females) between May 2010 and May 2015. The primary in-hospital outcome was all-cause mortality. The secondary outcome consisted of combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). The comparison between groups was performed using the chi-square and the t test, considering p < 0.05 as significant. In the long term, mortality and combined events were assessed using the Kaplan-Meier method, with a mean follow-up of 8.79 months. Results: The mean age was 60.3 years for males and 64.6 for females (p < 0.0001). The most prevalent risk factor was systemic arterial hypertension in 72.9% of the women and 67.8% of the men (p = 0.001). Percutaneous coronary intervention was carried out in 44.9% of the males and 35.4% of the females (p < 0.0001), and coronary artery bypass grafting (CABG) was performed in 17% of the males and 11.8% of females (p < 0.0001), with a higher prevalence of three-vessel coronary artery disease in males (27.3% vs. 16.2%, p < 0.0001). Approximately 79.9% of the female patients received a diagnosis of acute coronary syndrome without ST-segment elevation, while in the male patients, this diagnosis was attained in 71.5% (p < 0.0001). No significant differences were observed between the groups in the short and long term, regarding both mortality and the combined events. Conclusion: Several gender-related differences were observed in patients with acute coronary syndrome regarding the demographic characteristics, coronary artery disease pattern and implemented treatment. However, the prognostic evolution was similar between the groups.


Resumo Fundamento: Existem diferenças relatadas entre pacientes com síndrome coronariana aguda, de acordo com o sexo. A descrição deste achado comparativo em registro brasileiro ainda não foi documentada. Objetivo: Comparar pacientes do sexo masculino vs. feminino quanto a características basais, achados coronarianos, tratamento e prognóstico intra-hospitalar e em longo prazo. Métodos: Trata-se de estudo retrospectivo, multicêntrico e observacional, no qual foram incluídos 3.745 pacientes (2.437 do sexo masculino e 1.308 do sexo feminino) entre maio de 2010 e maio de 2015. O desfecho primário intra-hospitalar foi mortalidade por todas as causas. O desfecho secundário foi eventos combinados (choque cardiogênico, reinfarto, morte, acidente vascular cerebral e sangramento). A comparação entre grupos foi realizada por meio de qui-quadrado e teste t, sendo considerado significativo p < 0,05. Em longo prazo, foram avaliados a mortalidade e os eventos combinados pelo método Kaplan-Meier, com seguimento médio de 8,79 meses. Resultados: A média de idade foi de 60,3 anos no sexo masculino e 64,6 no feminino (p < 0,0001). O fator de risco mais prevalente foi hipertensão arterial sistêmica em 72,9% das mulheres e 67,8% nos homens (p = 0,001). Intervenção coronária percutânea foi realizada em 44,9% no sexo masculino e 35,4% no feminino (p < 0,0001), e revascularização miocárdica cirúrgica em 17% no sexo masculino e 11,8% no feminino (p < 0,0001), com maior prevalência de padrão coronariano triarterial no sexo masculino (27,3% vs. 16,2%; p < 0,0001). Cerca de 79,9% dos pacientes do sexo feminino enquadraram-se no diagnóstico de síndrome coronariana aguda sem supradesnivelamento do segmento ST, enquanto no sexo masculino este número foi de 71,5% (p < 0,0001). Em curto e longo prazos não se observaram diferenças significativas entre os grupos, tanto em mortalidade quanto em eventos combinados. Conclusão: Observaram-se múltiplas diferenças relacionadas ao sexo em pacientes com síndrome coronariana aguda no que se refere a características demográficas, padrão coronariano e tratamento adotado. No entanto, a evolução prognóstica foi semelhante entre os grupos.

RESUMO

BACKGROUND: Some small studies have related higher levels of thyrotropin (TSH) to potentially worse prognosis in acute coronary syndromes. However, this relationship remains uncertain. OBJECTIVE: To analyze the outcomes of patients with acute coronary syndromes in relation to the value of TSH at admission. METHODS: Observational and retrospective study with 505 patients (446 in group I [TSH ≤ 4 mIU/L] and 59 in group II [TSH > 4 mIU/L]) with acute coronary syndromes between May 2010 and May 2014. We obtained data about comorbidities and the medications used at the hospital. The primary endpoint was in-hospital all-cause death. The secondary endpoint included combined events (death, non-fatal unstable angina or myocardial infarction, cardiogenic shock, bleeding and stroke). Comparisons between groups were made by one-way ANOVA and chi-square test. Multivariate analysis was determined by logistic regression. Analyses were considered significant when p < 0.05. RESULTS: Significant differences between groups I and II were observed regarding the use of enoxaparin (75.2% vs. 57.63%, p = 0.02) and statins (84.08% vs. 71.19%, p < 0.0001), previous stroke (5.83% vs. 15.25%, p = 0.007), combined events (14.80% vs. 27.12%, OR = 3.05, p = 0.004), cardiogenic shock (4.77% vs. 6.05%, OR = 4.77, p = 0.02) and bleeding (12.09% vs. 15.25%, OR = 3.36, p = 0.012). CONCLUSIONS: In patients with acute coronary syndromes and TSH > 4 mIU/L at admission, worse prognosis was observed, with higher incidences of in-hospital combined events, cardiogenic shock and bleeding.

RESUMO

INTRODUCTION: Despite having higher sensitivity as compared to conventional troponins, sensitive troponins have lower specificity, mainly in patients with renal failure. OBJECTIVE: Study aimed at assessing the sensitive troponin I levels in patients with chest pain, and relating them to the existence of significant coronary lesions. METHODS: Retrospective, single-center, observational. This study included 991 patients divided into two groups: with (N = 681) and without (N = 310) significant coronary lesion. For posterior analysis, the patients were divided into two other groups: with (N = 184) and without (N = 807) chronic renal failure. The commercial ADVIA Centaur® TnI-Ultra assay (Siemens Healthcare Diagnostics) was used. The ROC curve analysis was performed to identify the sensitivity and specificity of the best cutoff point of troponin as a discriminator of the probability of significant coronary lesion. The associations were considered significant when p < 0.05. RESULTS: The median age was 63 years, and 52% of the patients were of the male sex. The area under the ROC curve between the troponin levels and significant coronary lesions was 0.685 (95% CI: 0.65 - 0.72). In patients with or without renal failure, the areas under the ROC curve were 0.703 (95% CI: 0.66 - 0.74) and 0.608 (95% CI: 0.52 - 0.70), respectively. The best cutoff points to discriminate the presence of significant coronary lesion were: in the general population, 0.605 ng/dL (sensitivity, 63.4%; specificity, 67%); in patients without renal failure, 0.605 ng/dL (sensitivity, 62.7%; specificity, 71%); and in patients with chronic renal failure, 0.515 ng/dL (sensitivity, 80.6%; specificity, 42%). CONCLUSION: In patients with chest pain, sensitive troponin I showed a good correlation with significant coronary lesions when its level was greater than 0.605 ng/dL. In patients with chronic renal failure, a significant decrease in specificity was observed in the correlation of troponin levels and severe coronary lesions.

RESUMO

Abstract Background: Some small studies have related higher levels of thyrotropin (TSH) to potentially worse prognosis in acute coronary syndromes. However, this relationship remains uncertain. Objective: To analyze the outcomes of patients with acute coronary syndromes in relation to the value of TSH at admission. Methods: Observational and retrospective study with 505 patients (446 in group I [TSH ≤ 4 mIU/L] and 59 in group II [TSH > 4 mIU/L]) with acute coronary syndromes between May 2010 and May 2014. We obtained data about comorbidities and the medications used at the hospital. The primary endpoint was in-hospital all-cause death. The secondary endpoint included combined events (death, non-fatal unstable angina or myocardial infarction, cardiogenic shock, bleeding and stroke). Comparisons between groups were made by one-way ANOVA and chi-square test. Multivariate analysis was determined by logistic regression. Analyses were considered significant when p < 0.05. Results: Significant differences between groups I and II were observed regarding the use of enoxaparin (75.2% vs. 57.63%, p = 0.02) and statins (84.08% vs. 71.19%, p < 0.0001), previous stroke (5.83% vs. 15.25%, p = 0.007), combined events (14.80% vs. 27.12%, OR = 3.05, p = 0.004), cardiogenic shock (4.77% vs. 6.05%, OR = 4.77, p = 0.02) and bleeding (12.09% vs. 15.25%, OR = 3.36, p = 0.012). Conclusions: In patients with acute coronary syndromes and TSH > 4 mIU/L at admission, worse prognosis was observed, with higher incidences of in-hospital combined events, cardiogenic shock and bleeding.


Resumo Fundamento: Estudos pequenos têm relacionado níveis mais elevados de hormônio tireoestimulante (TSH) a pior prognóstico em pacientes com síndrome coronariana aguda (SCA). Tal relação, no entanto, permanece incerta. Objetivo: Analisar os desfechos de pacientes com SCA, relacionando-os aos níveis de TSH medidos no setor de emergência. Métodos: Estudo retrospectivo observacional incluindo 505 pacientes com SCA (446 no grupo I: TSH ± 4 mUI/L; 59 no grupo II: TSH > 4 mUI/L) entre maio de 2010 e maio de 2014. Dados sobre comorbidades e medicamentos usados foram obtidos. O desfecho primário foi mortalidade intra-hospitalar por todas as causas. O desfecho secundário incluiu eventos combinados (morte, angina instável não fatal ou infarto do miocárdio, choque cardiogênico, sangramento e acidente vascular encefálico). A comparação entre grupos foi realizada através de ANOVA de uma via e teste do qui-quadrado. A análise multivariada foi realizada por regressão logística, adotando-se o nível de significância de p < 0,05. Resultados: Diferenças significativas foram observadas entre os grupos I e II relacionadas ao uso de enoxaparina (75,2% vs. 57,63%; p = 0,02) e estatinas (84,08% vs. 71,19%; p < 0,0001), acidente vascular encefálico prévio (5,83% vs. 15,25%; p = 0,007), eventos combinados (14,80% vs. 27,12%, OR = 3,05; p = 0,004), choque cardiogênico (4,77% vs. 6,05%, OR = 4,77; p = 0,02) e sangramento (12,09% vs. 15,25%, OR = 3,36; p = 0,012). Conclusão: Em pacientes com SCA e TSH > 4 mUI/L à admissão hospitalar, observou-se pior prognóstico associado à maior incidência de eventos combinados intra-hospitalares, choque cardiogênico e sangramentos.

Resumo Fundamento: Apesar de apresentar maior sensibilidade em comparação às troponinas convencionais, as troponinas sensíveis apresentam menor especificidade, principalmente em pacientes com insuficiência renal. Objetivo: Avaliar os valores de troponina I sensível em pacientes com dor torácica, relacionando-os à presença de lesões coronarianas significativas. Métodos: Estudo retrospectivo, unicêntrico e observacional. Foram incluídos 991 pacientes, divididos em dois grupos: com (N = 681) ou sem lesão coronariana (N = 310). Para análise posterior, os pacientes foram separados em outros dois grupos: com (N = 184) ou sem insuficiência renal (N = 807). A troponina utilizada pertence ao kit comercial ADVIA Centaur® TnI-Ultra (Siemens Healthcare Diagnostics). A análise foi feita por curva ROC para identificar a sensibilidade e a especificidade do melhor ponto de corte da troponina como discriminador de probabilidade de lesão coronariana. As associações foram consideradas significativas quando p < 0,05. Resultados: Cerca de 52% dos pacientes eram do sexo masculino e a idade mediana da amostra foi de 63 anos. A área sob a curva ROC entre os valores de troponina e lesões coronarianas significativas foi de 0,685 (IC 95%: 0,65 - 0,72). Em pacientes sem e com insuficiência renal, as áreas sob a curva foram 0,703 (IC 95%: 0,66 - 0,74) e 0,608 (IC 95%: 0,52 - 0,70), respectivamente. Os melhores pontos de corte para discriminar a presença de lesão coronária significativa foram: 0,605 ng/dL (sensibilidade de 63,4%, especificidade de 67%) no grupo geral, 0,605 ng/dL (sensibilidade de 62,7% e especificidade de 71%) em pacientes sem insuficiência renal e 0,515 ng/dL (sensibilidade de 80,6% e especificidade de 42%) no grupo com insuficiência renal crônica. Conclusão: Na população avaliada de pacientes com dor torácica, a troponina I sensível apresentou boa correlação com lesões coronarianas significativas quando acima de 0,605 ng/dL. Em pacientes com insuficiência renal crônica, observamos uma queda importante de especificidade na correlação dos valores com lesões coronarianas graves.

RESUMO

Fundamento: Diversos estudos experimentais têm mostrado redução de marcadores inflamatórios associados às doses mais elevadas de estatinas em pacientes com síndrome coronariana aguda (SCA). No entanto, a implicação clínica da dose de estatina na fase aguda da SCA ainda é incerta. Objetivo: Comparar desfechos em curto e longo prazo entre pacientes com SCA que receberam doses mais elevadas de atorvastatina versus baixas doses de atorvastatina iniciadas nas primeiras 24 horas da admissão hospitalar. Métodos: Para tal, os pacientes foram divididos em dois grupos: grupo I (N = 464): dose de atorvastatina 40 mg/dia. Foram obtidos dados demográficos, exames laboratoriais, medicações utilizadas e tratamento coronário adotado. Análise estatística: O desfecho primário foi mortalidade por todas as causas. A comparação entre grupos foi realizada através de Q-quadrado e teste T. A análise multivariada de desfechos intrahospitalares foi realizada por regressão logística, sendo considerado significativo p < 0,05. Em longo prazo foi avaliada a mortalidade e eventos combinados pelo método Kaplan-Meier com seguimento médio de 8,79 meses. Resultados: Na análise de desfechos intrahospitalares, não se observaram diferenças significativas entre os grupos I e II. Em longo prazo o grupo II apresentou menor mortalidade em relação ao grupo I (3,9% vs. 8,4%, p = 0,013), respectivamente. Conclusão: Diferenças favoráveis e significativas foram observadas em relação à mortalidade em longo prazo em pacientes com SCA que receberam desde a fase aguda doses elevadas de atorvastatina


Background: Recent experimental studies have described reduction in inflammatory markers related to higher doses of statins in patients with acute coronary syndromes (ACS). However, the clinical implication of the dose of statin in the acute phase of the ACS remains uncertain. Objective: To compare the outcomes in short and long terms among patients with acute coronary syndromes that received higher doses of atorvastatin versus low doses of atorvastatin started in the first 24 hours of hospital admission.Methods: For such, the patients were divided in two groups: group I (N = 464): atorvastatin dose: 40 mg/day. Demographic data, laboratory exams, medications used and coronary treatment adopted were obtained. Statistical analysis: The primary outcome was mortality from all causes. The comparison between groups was made by T-test and Q-square. Multivariative analysis of in-hospital outcomes were determined by logistic regression, considered significant when p < 0.05. In long-term, the mortality and combined events by the Kaplan-Meier method were assessed, with median follow-up of 8.79 months. Results: In the analysis of in-hospital outcomes, no significant differences were observed between groups I and II. In the long-term, group II presented lower mortality in comparison with group 9 (8.4% vs. 3.9%, p = 0.013). Conclusions: Favorable and significant differences were observed in relation to long-term mortality in patients with ACS that received high doses of atorvastatin since the acute phase
