ABSTRACT

Background: Coronary artery bypass grafting (CABG) is an important treatment option for obstructive coronary artery disease, but it represents a high expense for paying sources.The complications of CABG impose an additional expense to the procedure that is not yet clearly established. Objective: To determine the economic impact of postoperative complications of CABG during hospitalization in a hospital of the unified health system (SUS). Methods: This is an observational study involving 240 patients undergoing isolated CABG in a reference hospital in cardiology in 2013. Patients aged over 30 years with proven coronary artery disease and indication to perform CRVM were included. Patients who performed CRVM associated with other procedures were excluded. Results: The average cost of hospitalization was R$ 22,647.24 (SD = R$ 28,105.66). In 97 patients who presented some complication the average cost was R$ 35,400.28 (SD = R$ 40,509.47), and in the 143 patients without complications the average cost was R$ 13,996.57 (SD = R$ 5,800.61) (p < 0.001). Expenditures ranged from R$ 17,344.37 in patients with one complication up to R$ 104,596.52 in patients with five complications (p < 0.001). Conclusions: The occurrence of complications during hospitalization for CABG dignificantly increases the costs of the procedure, but the magnitude of this increase depends on the type of complication developed, and higher expenses related to cardiovascular complications, infections and bleeding. With this information, managers can improve the allocation of resources to health

ABSTRACT

Background: Cardiovascular diseases are a major cause of mortality and morbidity. Myocardial revascularization surgery may be indicated for the relief of symptoms and to reduce mortality. However, surgery is a costly procedure and the impact of the number of cardiovascular risk factors on the cost of the procedure has not been established. Objectives: To identify the impact of risk factors for coronary artery disease on myocardial revascularization surgery cost. Methods: We selected 239 patients undergoing myocardial revascularization surgery at the National Institute of Cardiology in the period from 01 January to 31 December 2013. We included patients aged over 30 years, with indication for the procedure. Patients undergoing combined procedures were excluded. Results: Seven patients had only one risk factor, 32 patients had two risk factors, 75 patients had 3 risk factors, 78 patients had four risk factors, 36 patients had 5 risk factors and 11 patients presented 6 risk factors. The total costs, on average, was R$ 14,143.22 in the group with 1 risk factor, R$ 18,380.40 in the group with 2 risk factors, R$ 21,229.51 in the group with 3 risk factors, R$ 24,620.86 in the group with 4 risk factors, R$ 21,337.92 in the group with 5 risk factors and R$ 36,098,35 in the group with 6 risk factors (p = 0.441). Conclusion: This study demonstrates that, in a public referral center for highly complex cardiology procedures, there was no significant correlation between the number of cardiovascular risk factors and hospitalization costs


Fundamentos: As doenças cardiovasculares representam uma importante causa de mortalidade e morbidade. A cirurgia de revascularização do miocárdio pode ser indicada para o alívio dos sintomas e para diminuir a mortalidade. Entretanto, a cirurgia é um procedimento de custo elevado e não está estabelecido o impacto do número de fatores de risco cardiovasculares nos gastos do procedimento. Objetivos: Identificar o impacto dos fatores de risco para a doença arterial coronariana nos gastos com a cirurgia de revascularização do miocárdio. Métodos: Foram selecionados 239 pacientes submetidos à cirurgia de revascularização do miocárdio isolada no Instituto Nacional de Cardiologia no período entre 01 de Janeiro a 31 de Dezembro de 2013. Foram incluídos pacientes com idade superior a 30 anos e indicação de revascularização cirúrgica do miocárdio. Foram excluídos os pacientes submetidos a procedimentos combinados. Resultados: Sete pacientes apresentaram apenas 1 fator de risco, 32 pacientes apresentaram 2 fatores de risco, 75 pacientes apresentaram 3 fatores de risco, 78 pacientes apresentaram 4 fatores de risco, 36 pacientes apresentaram 5 fatores de risco e 11 pacientes apresentaram 6 fatores de risco. O total dos gastos, em média, foi de R$ 14 143,22 no grupo com 1 fator de risco, R$ 18 380,40 no grupo com 2 fatores de risco, R$ 21 229,51 no grupo com 3 fatores de risco, R$ 24 620,86 no grupo com 4 fatores de risco, R$ 21 337,92 no grupo com 5 fatores de risco e R$ 36 098,35 no grupo com 6 fatores de risco (p = 0,441). Conclusão: Este trabalho demonstra que, em uma unidade pública de referência para a realização de procedimentos cardiológicos de alta complexidade, não houve uma correlação significativa entre o número de fatores de risco cardiovascular e os custos da internação

ABSTRACT

FUNDAMENTO: A morte súbita é a principal causa de óbito na doença de Chagas, acometendo pacientes mesmo em fases precoces da doença. É reconhecido o comprometimento do sistema nervoso autônomo nessa doença e seu potencial como deflagrador de arritmias malignas quando associado a alterações estruturais ou metabólicas. OBJETIVO: Buscamos identificar, em pacientes chagásicos com função sistólica preservada, o comprometimento do sistema nervoso autônomo e sua associação com anticorpos funcionalmente ativos contra receptores anti-m2 e anti-β1. MÉTODOS: Mediante análise espectral da variabilidade RR durante teste de inclinação passiva, pacientes chagásicos crônicos foram comparados com controles saudáveis pareados por idade. Posteriormente, a associação de disfunção autonômica com anticorpos funcionalmente ativos com ação anti-m2 e anti-β1 foi pesquisada pelo método de Langendorf. RESULTADOS: Observamos que pacientes chagásicos sem disfunção ventricular expressam atividade parassimpática ante um estímulo vagal, porém com menor intensidade em relação aos controles. Pacientes chagásicos com anticorpos anti-m2 ou anti-β1 apresentaram uma redução ainda mais expressiva da resposta vagal durante a arritmia sinusal respiratória, independentemente da presença de lesão estrutural. Entretanto, a associação de ambos promoveu resposta ao estímulo vagal similar aos chagásicos sem a presença dos mesmos. CONCLUSÃO: A menor reserva vagal em pacientes chagásicos com função preservada esteve associada à presença de anticorpos anti-m2 ou anti-β1 funcionalmente ativos, e não à presença de lesão cardíaca estrutural.


BACKGROUND: Sudden death is the leading cause of death in Chagas' disease, affecting patients even in the early stages of the disease. The impairment of the autonomic nervous system in this disease has been recognized, as well as its potential as a trigger for malignant arrhythmias when associated with structural or metabolic changes. OBJECTIVE: We sought to identify, in Chagas patients with preserved systolic function, the impairment of the autonomic nervous system and its association with functionally active anti-m2 and anti-β1 receptor antibodies. METHODS: Using spectral analysis of RR variability during passive tilt test, chronic chagasic patients were compared with healthy controls matched for age. Subsequently, the association of autonomic dysfunction with functionally active antibodies with anti-m2 and anti-β1 action was investigated by the Langendorf method. RESULTS: We observed that patients with Chagas disease without ventricular dysfunction express parasympathetic activity against a vagal stimulus, however with less intensity compared to controls. Chagasic patients with anti-m2 or anti-β1 antibodies showed a further significant reduction of the vagal response during respiratory sinus arrhythmia, regardless of the presence of structural lesion. However, the association of both factors promoted response to vagal stimulation similar to that seen in Chagas disease without their presence. CONCLUSION: The lower vagal reserve in Chagas patients with preserved function was associated with functionally active anti-m2 or anti-β1 antibodies, and not with the presence of structural heart lesion.
