RESUMO

AIMS: Prognostic models of sudden cardiac death (SCD) typically incorporate data at only a single time-point. We investigated independent predictors of SCD addressing the impact of integrating time-varying covariates to improve prediction assessment. METHODS AND RESULTS: We studied 8,399 patients enrolled in the PARADIGM-HF trial and identified independent predictors of SCD (n=561, 36% of total deaths) using time-updated multivariable-adjusted Cox models, classification and regression tree (CART), and logistic regression analysis. Compared with patients who were alive or died from non-sudden cardiovascular deaths, patients who suffered a SCD displayed a distinct temporal profile of New York Heart Association (NYHA) class, heart rate and levels of 3 biomarkers (albumin, uric acid and total bilirubin), with significant differences observed more than 1 year prior to the event (p interaction <0.001). In multivariable models adjusted for baseline covariates, 7 time-updated variables independently contributed to SCD risk (incremental likelihood chi-square=46.2). CART analysis identified that baseline variables (implantable cardioverter defibrillator use and N-terminal prohormone of B-type natriuretic peptide levels) and time-updated covariates (NYHA class, total bilirubin, and total cholesterol) improved risk stratification. CART-defined subgroup of highest risk had nearly an 8-fold increment in SCD hazard (hazard ratio=7.7, 95% confidence interval 3.6-16.5; p<0.001). Finally, changes over time in heart rate, NYHA class, blood urea nitrogen and albumin levels were associated with differential risk of sudden versus non-sudden cardiovascular deaths (p<0.05). CONCLUSIONS: Beyond single time-point assessments, distinct changes in multiple cardiac-specific and systemic variables improved SCD risk prediction and were helpful in differentiating mode of death in chronic HF.

RESUMO

Respiratory syncytial virus (RSV) is the main cause of lower respiratory disease in infants and children under five years of age. As there is no specific treatment for RSV infections, prophylaxis with the specific monoclonal antibody palivizumab (PVZ) has been widely recommended for high-risk cases during the RSV season. The present study aimed to evaluate the effectiveness of a public prophylaxis program with palivizumab on the incidence of hospitalizations for lower respiratory tract infections and RSV in children at high risk for severe RSV infections. A retrospective cohort study was carried out with preterm children or children under two years of age with chronic lung disease or hemodynamically significant congenital heart disease; the children were selected on the basis of their exposure status, which was defined as the prophylactic use of palivizumab during the RSV season. Children were enrolled retrospectively in two hospitals located in Southern Brazil, from May 2009 to August 2016. In a sample of 129 children, 69 (53.5%) received palivizumab and adherence to three or more doses was observed in 78%; 60 (46.5%) children did not receive palivizumab. PVZ prophylaxis was independently associated with a 66% reduction in hospitalizations for any cause (26/69 - 37.7%) in the PVZ group and 34/60 (56.7%) in the control group). A 52% reduction in hospitalizations due to lower respiratory tract infection was observed in the PVZ group (15/69 -21.7%) and 25/60 (41.7%) in the control group. These findings suggest that, for the group of studied patients, the adoption of an RSV prophylaxis scheme reached the same effectiveness as those described in previous clinical trials.

RESUMO

Axillary vein puncture guided by ultrasound (US-Ax) versus cephalic vein dissection in pacemaker and defibrillator implant: a multicenter randomized clinical trial is a recently published study in which 88 patients were randomized in a 1:1 fashion to one of the two methods. Even being performed by operators with not previous ultrasound-guided axillary vein puncture experience, this group presented a higher success rate, lower procedural time and comparable complication incidence.

RESUMO

OBJECTIVES: To describe clinical characteristics, laboratory and imaging findings, as well as in-hospital outcomes of COVID-19 patients admitted to Brazilian hospitals. METHODS: Cohort study of laboratory-confirmed COVID-19 patients hospitalized from March to September 2020 at 25 hospitals. Study data were collected from medical records using Research Electronic Data Capture (REDCap) tools. Multivariate Poisson regression model was used to assess risk factors for in-hospital mortality. RESULTS: Of 2054 patients (52.6% male, median age 58 years old), in-hospital mortality was 22.0%, and 47.6% among those treated in the ICU. Hypertension (52.9%), diabetes (29.2%) and obesity (17.2%) were the most prevalent comorbidities. Overall, 32.5% required invasive mechanical ventilation and 12.1% kidney replacement therapy. Septic shock was observed in 15.0%, nosocomial infection in 13.1%, thromboembolism in 4.1% and acute heart failure in 3.6%. Age ≥65 years-old, chronic kidney disease, hypertension, C-reactive protein ≥100 mg/dL, platelet count <100 × 109/L, oxygen saturation <90%, supplementary oxygen requirement and invasive mechanical ventilation at admission were independently associated with a higher risk of in-hospital mortality. The overall use of antimicrobials was 87.9%. CONCLUSIONS: This study provides characteristics and in-hospital outcomes of consecutively hospitalized patients with confirmed COVID-19 in Brazil. Easily assessed parameters at hospital admission were independently associated with a higher risk of death. The high frequency of antibiotic use points to an over-use of antimicrobials in COVID-19 patients.

RESUMO

BACKGROUND: This Consensus Statement introduces a standardized framework, in a checklist format, to support future development and reporting of TDABC studies in healthcare, and to encourage their reproducibility. Additionally, it establishes the first formal networking of TDABC researchers through the creation of the TDABC in Healthcare Consortium. METHODS: A consensus group of researchers reviewed the most relevant TDABC studies available in Medline and Scopus databases to identify the initial elements of the checklist. Using a Focus Group process, each element received a recommendation regarding where in the scientific article section it should be placed and whether the element was required or suggested. A questionnaire was circulated with expert researchers in the field to provide additional recommendations regarding the content of the checklist and the strength of recommendation for each included element. RESULTS: The TDABC standardized framework includes 32 elements, provides recommendations where in the scientific article to include each element, and comments on the strength of each recommendation. All 32 elements were validated, with 21 elements classified as mandatory and 11 as suggested but not mandatory. CONCLUSIONS: This is the first standardized framework to support the development and reporting of TDABC research in healthcare and to stablish a community of experts in TDABC methodology. We expect that it can contribute to scale strategies that would result in cost-savings outcomes and in value-oriented strategies that can be adopted in healthcare systems and institutions.

RESUMO

OBJECTIVE: This study aims to describe the clinical characteristics and predictors of mechanical ventilation of adult inpatients with COVID-19 in a single center. METHODS: A retrospective cohort study was performed and included adult inpatients hospitalized from March 17th to May 3rd, 2020, who were diagnosed with SARS-CoV-2 infection. Clinical and demographic characteristics were extracted from electronic medical records. RESULTS: Overall, 88 consecutive patients were included in this study. The median age of the patients was 63 years (IQR 49 - 71); 59 (67%) were male, 65 (86%) had a college degree and 67 (76%) had at least one comorbidity. Twenty-nine (33%) patients were admitted to the intensive care unit, 18 (20%) patients needed mechanical ventilation, and 9 (10.2%) died during hospitalization. The median length of stay in the intensive care unit and the median duration of mechanical ventilation was 23 and 29.5 days, respectively. An age ≥ 65 years was an independent risk factor for mechanical ventilation (OR 8.4 95%CI 1.3 - 55.6 p = 0.02). CONCLUSION: Our findings describe the first wave of Brazilian patients hospitalized for COVID-19. Age was the strongest predictor of respiratory insufficiency and the need for mechanical ventilation in our population.

RESUMO

Background: Physicians commonly judge whether a myocardial infarction (MI) is type 1 (thrombotic) vs type 2 (supply/demand mismatch) based on clinical information. Little is known about the accuracy of physicians' clinical judgement in this regard. We aimed to determine the accuracy of physicians' judgement in the classification of type 1 vs type 2 MI in perioperative and nonoperative settings. Methods: We performed an online survey using cases from the Optical Coherence Tomographic Imaging of Thrombus (OPTIMUS) Study, which investigated the prevalence of a culprit lesion thrombus based on intracoronary optical coherence tomography (OCT) in patients experiencing MI. Four MI cases, 2 perioperative and 2 nonoperative, were selected randomly, stratified by etiology. Physicians were provided with the patient's medical history, laboratory parameters, and electrocardiograms. Physicians did not have access to intracoronary OCT results. The primary outcome was the accuracy of physicians' judgement of MI etiology, measured as raw agreement between physicians and intracoronary OCT findings. Fleiss' kappa and Gwet's AC1 were calculated to correct for chance. Results: The response rate was 57% (308 of 536). Respondents were 62% male; median age was 45 years (standard deviation ± 11); 45% had been in practice for > 15 years. Respondents' overall accuracy for MI etiology was 60% (95% confidence interval [CI] 57%-63%), including 63% (95% CI 60%-68%) for nonoperative cases, and 56% (95% CI 52%-60%) for perioperative cases. Overall chance-corrected agreement was poor (kappa = 0.05), consistent across specialties and clinical scenarios. Conclusions: Physician accuracy in determining MI etiology based on clinical information is poor. Physicians should consider results from other testing, such as invasive coronary angiography, when determining MI etiology.

RESUMO

OBJECTIVE: New York Heart Association (NYHA) functional class plays a central role in heart failure (HF) assessment but might be unreliable in mild presentations. We compared objective measures of HF functional evaluation between patients classified as NYHA I and II in the Rede Brasileira de Estudos em Insuficiência Cardíaca (ReBIC)-1 Trial. METHODS: The ReBIC-1 Trial included outpatients with stable HF with reduced ejection fraction. All patients had simultaneous protocol-defined assessment of NYHA class, 6 min walk test (6MWT), N-terminal pro-brain natriuretic peptide (NT-proBNP) levels and patient's self-perception of dyspnoea using a Visual Analogue Scale (VAS, range 0-100). RESULTS: Of 188 included patients with HF, 122 (65%) were classified as NYHA I and 66 (35%) as NYHA II at baseline. Although NYHA class I patients had lower dyspnoea VAS Scores (median 16 (IQR, 4-30) for class I vs 27.5 (11-49) for class II, p=0.001), overlap between classes was substantial (density overlap=60%). A similar profile was observed for NT-proBNP levels (620 pg/mL (248-1333) vs 778 (421-1737), p=0.015; overlap=78%) and for 6MWT distance (400 m (330-466) vs 351 m (286-408), p=0.028; overlap=64%). Among NYHA class I patients, 19%-34% had one marker of HF severity (VAS Score >30 points, 6MWT <300 m or NT-proBNP levels >1000 pg/mL) and 6%-10% had two of them. Temporal change in functional class was not accompanied by variation on dyspnoea VAS (p=0.14). CONCLUSIONS: Most patients classified as NYHA classes I and II had similar self-perception of their limitation, objective physical capabilities and levels of natriuretic peptides. These results suggest the NYHA classification poorly discriminates patients with mild HF.

RESUMO

BACKGROUND: To evaluate the prognostic value of peak serum lactate and lactate clearance at several time points in cardiogenic shock treated with temporary mechanical circulatory support (MCS) using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) or Impella CP®. METHODS: Serum lactate and clearance were measured before MCS and at 1 h, 6 h, 12 h, and 24 h post-MCS in 43 patients at four tertiary-care centers in Southern Brazil. Prognostic value was assessed by univariable and multivariable analysis and receiver operating characteristic (ROC) curves for 30-day mortality. RESULTS: VA-ECMO was the most common MCS modality (58%). Serum lactate levels at all time points and lactate clearance after 6 h were associated with mortality on unadjusted and adjusted analyses. Lactate levels were higher in non-survivors at 6 h, 12 h, and 24 h after MCS. Serum lactate > 1.55 mmol/L at 24 h was the best single prognostic marker of 30-day mortality [area under the ROC curve = 0.81 (0.67-0.94); positive predictive value = 86%). Failure to improve serum lactate after 24 h was associated with 100% mortality. CONCLUSIONS: Serum lactate was an important prognostic biomarker in cardiogenic shock treated with temporary MCS. Serum lactate and lactate clearance at 24 h were the strongest independent predictors of short-term survival.

RESUMO

Resumo Fundamento: O infarto agudo do miocárdio com supradesnivelamento do segmento ST (STEMI) é uma das principais apresentações clínicas da cardiopatia isquêmica. Dados de base populacional são relevantes para entendimento contemporâneo da epidemiologia da doença. Objetivo: Descrever incidência, manejo terapêutico, desfechos clínicos hospitalares e eventos cardiovasculares do primeiro ano de seguimento dos indivíduos hospitalizados por STEMI. Métodos: Estudo de coorte prospectiva de base populacional com registro consecutivo das hospitalizações por STEMI em uma cidade do Sul do Brasil entre 2011 e 2014. Foram incluídos indivíduos com STEMI que apresentaram sintomas de isquemia miocárdica aguda nas últimas 72 horas. Os valores de p < 0,05 foram considerados significativos. Resultados: A incidência anual de hospitalizações por STEMI foi de 108 casos por 100.000 habitantes. A incidência ajustada foi maior entre os mais velhos (risco relativo 64,9; IC95% 26,9 - 156,9; p para tendência linear < 0,001) e entre os homens (risco relativo 2,8; IC95% 2,3 - 3,3; p < 0,001). Ocorreram 530 hospitalizações durante o período avaliado e a taxa de reperfusão foi de 80,9%. A mortalidade hospitalar e a taxa de eventos cardiovasculares em 1 ano foram, respectivamente, 8,9% e 6,1%. Os mais velhos apresentaram maior mortalidade hospitalar (risco relativo 3,72; IC95% 1,57 - 8,82; p para tendência linear = 0,002) e mais eventos cardiovasculares em 1 ano (hazard ratio 2,35; IC95% 1,12 - 4,95; p = 0,03). Conclusão: Este registro demonstra abordagem terapêutica e mortalidade hospitalar semelhante às observadas em países desenvolvidos. Entretanto, a taxa de hospitalizações foi maior comparada com esses países.


Abstract Background: ST-segment elevation myocardial infarction (STEMI) is one of the main clinical manifestations of ischemic heart disease. Population-based data are relevant to better understand the current epidemiology of this condition. Objective: To describe the incidence, therapeutic management, hospital clinical outcomes and cardiovascular events in the first year of follow-up of individuals hospitalized for STEMI. Methods: Population-based prospective cohort study with consecutive registries of hospitalization for STEMI in a city in southern Brazil from 2011 to 2014. It included patients with STEMI who presented acute myocardial ischemia symptoms in the last 72 hours. A p-value < 0.05 was considered significant. Results: The annual incidence of STEMI hospitalizations was 108 cases per 100,000 inhabitants. Adjusted incidence was higher among older individuals (relative risk 64.9; 95% CI 26.9-156.9; p for linear trend < 0.001) and among men (relative risk 2.8; 95% CI 2.3-3.3; p < 0.001). There were 530 hospitalizations in the period under evaluation and the reperfusion rate reached 80.9%. Hospital mortality and the one-year follow-up cardiovascular event rate were, respectively, 8.9% and 6.1%. The oldest patients had higher hospital mortality (relative risk 3.72; 95% CI 1.57-8.82; p for linear trend = 0.002) and more one-year follow-up cardiovascular events (hazard ratio 2.35; 95% CI 1.12-4.95; p = 0.03). Conclusion: This study shows that both the therapeutic approach and hospital mortality are similar to the ones found in developed countries. However, the hospitalization rate was higher in these countries.

RESUMO

BACKGROUND: Data on the management and prognosis of patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease are limited in Brazil, showing that the available revascularization strategies should be investigated. OBJECTIVE: To assess the outcomes of complete revascularization versus treatment of the culprit artery only in patients with STEMI and multivessel disease. METHODS: A prospective cohort study was conducted at two medical centers in southern Brazil with a 1-year follow-up after the index procedure. The primary outcome was a composite of cardiac death, reinfarction, or recurrent angina, while the secondary outcome was stroke, nonfatal cardiac arrest, major bleeding, or need for reintervention. The probability of outcomes occurring was compared between the groups using binary logistic regression. A p-value < 0.05 was considered statistically significant. RESULTS: Eighty-five patients were included. Their mean age was 62±12 years, and 61 (71.8%) were male. Fifty-eight (68.2%) were treated with complete revascularization and 27 (31.8%) with incomplete revascularization. The chance of both the primary and secondary outcomes occurring was significantly greater among patients treated with incomplete revascularization when compared to those treated with complete revascularization (odds ratio [OR] 5.1, 95% confidence interval [CI] 1.6-16.1 vs. OR 5.2, 95% CI 1.2-22.9, respectively), as well as cardiac death (OR 6.4, 95% CI 1.2-35.3). CONCLUSION: Registry data from two centers in southern Brazil demonstrate that the complete revascularization strategy is associated with a significant reduction in primary and secondary outcomes in a 1-year follow-up when compared to the incomplete revascularization strategy (Arq Bras Cardiol. 2020; 115(2):229-237).

RESUMO

Cardiac stimulation therapy has evolved significantly over the past 30 years. Currently, cardiac implantable electronic devices (CIED) are the mainstream therapy for many potentially lethal heart conditions, such as advanced atrioventricular block or sustained ventricular tachycardia or fibrillation. Despite sometimes being lifesaving, the implant is surgical and therefore carries all the inevitable intrinsic risks. In the process of technology evolution, one of the most important factors is to make it safer for the patient. In the context of CIED implants, complications include accidental puncture of intrathoracic structures. Alternative strategies to intrathoracic subclavian vein puncture include cephalic vein dissection or axillary vein puncture, which can be guided by fluoroscopy, venography or, more recently, ultrasound. In this article, the authors analyse the state of the art of ultrasound-guided axillary vein puncture using evidence from landmark studies in this field.

RESUMO

Resumo Fundamento São restritos os dados sobre o manejo e o prognóstico dos pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST) com acometimento multiarterial no Brasil, o que mostra a necessidade de investigar as estratégias de revascularização disponíveis. Objetivo Avaliar os desfechos relacionados à revascularização completa em comparação com o tratamento da artéria culpada em pacientes multiarteriais com IAMCSST. Métodos Foi realizada um estudo de coorte prospectiva em dois centros de hemodinâmica do Sul do Brasil, com seguimento de 1 ano após a intervenção índice. O desfecho primário foi composto de óbito cardiovascular, reinfarto ou angina recorrente e secundários acidente vascular encefálico, parada cardiorrespiratória não fatal, sangramento maior ou necessidade de reintervenção. A probabilidade de ocorrência de desfechos foi comparada entre os grupos através de regressão logística binária. Considerou-se como estatisticamente significativo o valor de probabilidade < 0,05. Resultados Participaram 85 pacientes, com média de idade de 62±12 anos, sendo 61 (71,8%) do sexo masculino. Cinquenta e oito (68,2%) pacientes receberam a estratégia de revascularização completa e 27 (31,8%), a de revascularização incompleta. A chance de ocorrência tanto do desfecho primário quanto do secundário foi significativamente maior entre os indivíduos tratados com revascularização incompleta quando comparados com os tratados com estratégia completa [razão de chances (OR) 5,1, intervalo de confiança de 95% (IC95%) 1,6-16,1 vs. OR 5,2, IC95% 1,2-22,9, respectivamente], assim como os óbitos cardiovasculares (OR 6,4, IC95% 1,2-35,3). Conclusão Dados deste registro regional, de dois centros do Sul do Brasil, demonstram que a estratégia de revascularização completa esteve associada à redução significativa dos desfechos primário e secundário no seguimento de 1 ano quando comparada à estratégia de revascularização incompleta.
