RESUMEN

BACKGROUND: Diabetes mellitus (DM) is associated with increased cardiovascular (CV) risk. We compared health-related quality of life (HRQoL), healthcare resource utilization (HRU), and clinical outcomes of stable post-myocardial infarction (MI) patients with and without DM. HYPOTHESIS: In post-MI patients, DM is associated with worse HRQoL, increased HRU, and worse clinical outcomes. METHODS: The prospective, observational long-term risk, clinical management, and healthcare Resource utilization of stable coronary artery disease study obtained data from 8968 patients aged ≥50 years 1 to 3 years post-MI (369 centers; 25 countries). Patients with ≥1 of the following risk factors were included: age ≥65 years, history of a second MI >1 year before enrollment, multivessel coronary artery disease, creatinine clearance ≥15 and <60 mL/min, and DM treated with medication. Self-reported health status was assessed at baseline, 1 and 2 years and converted to EQ-5D scores. The main outcome measures were baseline HRQoL and HRU during follow-up. RESULTS: DM at enrollment was 33% (2959 patients, 869 insulin treated). Mean baseline EQ-5D score (0.86 vs 0.82; P < .0001) was higher; mean number of hospitalizations (0.38 vs 0.50, P < .0001) and mean length of stay (LoS; 9.3 vs 11.5; P = .001) were lower in patients without vs with DM. All-cause death and the composite of CV death, MI, and stroke were significantly higher in DM patients, with adjusted 2-year rate ratios of 1.43 (P < .01) and 1.55 (P < .001), respectively. CONCLUSIONS: Stable post-MI patients with DM (especially insulin treated) had poorer EQ-5D scores, higher hospitalization rates and LoS, and worse clinical outcomes vs those without DM. Strategies focusing specifically on this high-risk population should be developed to improve outcomes. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01866904 (https://clinicaltrials.gov).

RESUMEN

BACKGROUND: Globally, tobacco consumption continues to cause a huge burden of preventable diseases. Chile has been leading the tobacco burden ranking in the Latin American region for the last ten years; it has currently a 33. 3% prevalence of current smokers. METHODS: A microsimulation economic model was developed within the framework of a multi-country project in order to estimate the burden attributable to smoking in terms of morbidity, mortality, disability-adjusted life-years (DALYs), and direct costs of care. We also modelled the impact of increasing cigarettes' taxes on this burden. RESULTS: In Chile, 16,472 deaths were attributable to smoking in 2017, which represent around 16% of all deaths. This burden corresponds to 416,445 DALYs per year. The country's health system spends 1.15 trillion pesos annually (in Dec 2017 CLP, approx. U$D 1.8 billion) in health care treatment of illnesses caused by smoking. If the price of tobacco cigarettes was to be raised by 50%, around 13,665 deaths and 360,476 DALYs from smoking-attributable diseases would be averted in 10 years, with subsequent savings on health care costs, and increased tax revenue collection. In Chile, the tobacco tax collection does not fully cover the direct healthcare costs attributed to smoking. CONCLUSION: Despite a reduction observed on smoking prevalence between 2010 (40.6%) and 2017 (33.3%), this study shows that the burden of disease, and the economic toll due to smoking, remain high. As we demonstrate, a rise in the price of cigarettes could lead to a significant reduction of this burden, averting deaths and disability, and reducing healthcare spending.

RESUMEN

BACKGROUND: Clinical trials often report intervention efficacy in terms of the reduction in all-cause mortality between the treatment and control arms (i.e., an overall hazard ratio [oHR]) instead of the reduction in disease-specific mortality (i.e., a disease-specific hazard ratio [dsHR]). Using oHR to reduce all-cause mortality beyond the time horizon of the trial may introduce bias if the relative proportion of other-cause mortality increases with age. We sought to quantify this oHR extrapolation bias and propose a new approach to overcome this bias. METHODS: We simulated a hypothetical cohort of patients with a generic disease that increased background mortality by a constant additive disease-specific rate. We quantified the bias in terms of the percentage change in life expectancy gains with the intervention under an oHR compared with a dsHR approach as a function of the cohort start age, the disease-specific mortality rate, dsHR, and the duration of the intervention's effect. We then quantified the bias in a cost-effectiveness analysis (CEA) of implantable cardioverter-defibrillators based on efficacy estimates from a clinical trial. RESULTS: For a cohort of 50-year-old patients with a disease-specific mortality of 0.05, a dsHR of 0.5, a calculated oHR of 0.55, and a lifetime duration of effect, the bias was 28%. We varied these key parameters over wide ranges and the resulting bias ranged between 3 and 140%. In the CEA, the use of oHR as the intervention's effectiveness overestimated quality-adjusted life expectancy by 9% and costs by 3%, biasing the incremental cost-effectiveness ratio by - 6%. CONCLUSIONS: The use of an oHR approach to model the intervention's effectiveness beyond the time horizon of the trial overestimates its benefits. In CEAs, this bias could decrease the cost of a QALY, overestimating interventions' cost effectiveness.

RESUMEN

Ischaemic heart disease is the leading cause of death worldwide, with an increasing trend from 6.1 million deaths in 1990 to 9.5 million in 2016, markedly driven by rates observed in low/middle-income countries (LMIC). Improvements in myocardial infarction (MI) care are crucial for reducing premature mortality. We aimed to evaluate the main challenges for adequate MI care in LMIC, and possible strategies to overcome these existing barriers.Reperfusion is the cornerstone of MI treatment, but worldwide around 30% of patients are not reperfused, with even lower rates in LMIC. The main challenges are related to delays associated with patient education, late diagnosis and inadequate referral strategies, health infrastructure and insufficient funding. The implementation of regional MI systems of care in LMIC, systematising timely reperfusion strategies, access to intensive care, risk stratification and use of adjunctive medications have shown some successful strategies. Telemedicine support for remote ECG, diagnosis and organisation of referrals has proven to be useful, improving access to reperfusion even in prehospital settings. Organisation of transport and referral hubs based on anticipated delays and development of MI excellence centres have also resulted in better equality of care. Also, education of healthcare staff and task shifting may potentially widen access to optimal therapy.In conclusion, efforts have been made for the implementation of MI systems of care in LMIC, aiming to address particularities of the health systems. However, the increasing impact of MI in these countries urges the development of further strategies to improve reperfusion and reduce system delays.

RESUMEN

BACKGROUND: Heart conditions impose physical, social, financial and health-related quality of life limitations on individuals in Brazil. OBJECTIVES: This study assessed the economic burden of four main heart conditions in Brazil: hypertension, heart failure, myocardial infarction, and atrial fibrillation. In addition, the cost-effectiveness of telemedicine and structured telephone support for the management of heart failure was assessed. METHODS: A standard cost of illness framework was used to assess the costs associated with the four conditions in 2015. The analysis assessed the prevalence of the four conditions and, in the case of myocardial infarction, also its incidence. It further assessed the conditions' associated expenditures on healthcare treatment, productivity losses from reduced employment, costs of providing formal and informal care, and lost wellbeing. The analysis was informed by a targeted literature review, data scan and modelling. All inputs and methods were validated by consulting 15 clinicians and other stakeholders in Brazil. The cost-effectiveness analysis was based on a meta-analysis and economic evaluation of post-discharge programs in patients with heart failure, assessed from the perspective of the Brazilian Unified Healthcare System (Sistema Unico de Saude). RESULTS: Myocardial infarction imposes the greatest financial cost (22.4 billion reais/6.9 billion USD), followed by heart failure (22.1 billion reais/6.8 billion USD), hypertension (8 billion reais/2.5 billion USD) and, finally, atrial fibrillation (3.9 billion reais/1.2 billion USD). Telemedicine and structured telephone support are cost-effective interventions for achieving improvements in the management of heart failure. CONCLUSIONS: Heart conditions impose substantial loss of wellbeing and financial costs in Brazil and should be a public health priority.

Resumo Fundamento: As doenças cardíacas impõem limitações à qualidade de vida nos aspectos físicos, sociais, financeiros e de saúde no Brasil. Objetivos: Este estudo avaliou o custo de quatro importantes doenças cardíacas no Brasil: hipertensão, insuficiência cardíaca, infarto do miocárdio e fibrilação atrial. Além disso, avaliou a relação de custo-efetividade de telemedicina e suporte telefônico estruturado para o manejo de insuficiência cardíaca. Métodos: Um custo padrão da estrutura de enfermidade foi usado para avaliar os custos associados às quatro condições em 2015. Analisou-se a prevalência das quatro doenças e, em caso de infarto do miocárdio, também sua incidência. Avaliaram-se ainda as despesas associadas ao tratamento, a perda de produtividade a partir da redução do emprego, os custos do fornecimento de assistência formal e informal e o bem-estar perdido referentes às condições. A análise teve por base uma revisão de literatura-alvo, varredura de dados e modelagem. Todos os inputs e métodos foram validados por 15 clínicos consultores e outras partes interessadas no Brasil. A análise de custo-efetividade baseou-se em uma meta-análise e uma avaliação econômica de programas após a alta de pacientes com insuficiência cardíaca, considerados a partir da perspectiva do Sistema Único de Saúde do Brasil. Resultados: Infarto do miocárdio acarretou o mais alto custo financeiro (R$ 22,4 bilhões/6,9 bilhões de dólares), seguido de insuficiência cardíaca (R$ 22,1 bilhões/6,8 bilhões de dólares), hipertensão (R$ 8 bilhões/2,5 bilhões de dólares) e, finalmente, fibrilação atrial (R$ 3,9 bilhões/1,2 bilhão de dólares). Telemedicina e suporte telefônico estruturado são intervenções custo-efetivas para o aprimoramento do manejo da insuficiência cardíaca. Conclusões: As doenças cardíacas determinam substanciais custos financeiros e perda de bem-estar no Brasil e deveriam ser uma prioridade de saúde pública.

RESUMEN

OBJECTIVE: ST-segment elevation myocardial infarction (STEMI) has an important economic burden that poised the urgent need to evaluate its catastrophic medical expense. This study evaluates the first 5 years of the national health initiative called Popular Insurance (PI) at the National Institute of Cardiology in Mexico. STUDY DESIGN: Retrospective data analysis. METHODS: STEMI patients with (n=317) and without (n=260) PI were selected. Analysed variables included socio-economical context, management care, cost evaluation and three outcomes (mortality, hospital readmission and therapeutic adherence). Descriptive statistical analyses, Kaplan-Meier survival and Support Vector Machine models were used accordingly. RESULTS: Treatment costs were higher for PI-covered individuals (P=0.022) and only 1.89% of them remained in debt, in contrast to 16.15% of those without PI. Statistically significant differences were found in relation to days in hospital wards (P<0.001), imaging studies (P<0.001) and surgical materials (P=0.04). Survival analysis (P=0.44) and therapeutic adherence (P=0.38) showed no differences. Hospital readmission was predicted with an 81.97% accuracy. The most important predictive variables included were stent type, number of days at the coronary care unit and hospital wards. CONCLUSIONS: The PI has proven to be a successful program where no differences were found in terms of health care and survival, whereas it provides timely financial support for families facing catastrophic health challenging events.

RESUMEN

BACKGROUND: The effect of socioeconomic stressors on the incidence of cardiovascular disease (CVD) is currently open to debate. Using time-series analysis, our study aimed to evaluate the relationship between unemployment rate and hospital admission for acute myocardial infarction (AMI) and stroke in Brazil over a recent 11-year span. METHODS AND RESULTS: Data on monthly hospital admissions for AMI and stroke from March 2002 to December 2013 were extracted from the Brazilian Public Health System Database. The monthly unemployment rate was obtained from the Brazilian Institute for Applied Economic Research, during the same period. The autoregressive integrated moving average (ARIMA) model was used to test the association of temporal series. Statistical significance was set at p<0.05. From March 2002 to December 2013, 778,263 admissions for AMI and 1,581,675 for stroke were recorded. During this time period, the unemployment rate decreased from 12.9% in 2002 to 4.3% in 2013, while admissions due to AMI and stroke increased. However, the adjusted ARIMA model showed a positive association between the unemployment rate and admissions for AMI but not for stroke (estimate coefficient=2.81±0.93; p=0.003 and estimate coefficient=2.40±4.34; p=0.58, respectively). CONCLUSIONS: From 2002 to 2013, hospital admissions for AMI and stroke increased, whereas the unemployment rate decreased. However, the adjusted ARIMA model showed a positive association between unemployment rate and admissions due to AMI but not for stroke. Further studies are warranted to validate our findings and to better explore the mechanisms by which socioeconomic stressors, such as unemployment, might impact on the incidence of CVD.

RESUMEN

INTRODUCTION: The global epidemiologic scenario indicates an increase in cardiovascular disease rates, with special emphasis on acute myocardial infarction (AMI), owing to its large magnitude and severity. In Brazil, coronary diseases now account for about 5% of hospital admission expenditures. OBJECTIVE: To characterize the admissions in the Brazilian Unified Health System of patients with AMI, by identifying clusters suggested by a traditional cluster analysis and by a multiple correspondence analysis (MCA). METHODS: The records of the Hospital Information System/Brazilian Unified Health System with a primary diagnosis of AMI in the State of Rio de Janeiro, Brazil, 2002, were selected and subsequently related to the records of the Mortality Information System. Next, an MCA and a metric called the tolerance distance were used for cluster identification. The variable of interest was "hospital expenditures", classified into two categories (above and below BRL 905). RESULTS: "Higher costs" were associated with "use of the Intensive Care Unit (ICU)" and "moderate severity of the case" and "lower costs" with "low severity" and "nonuse of the ICU". On the other hand, high severity cases, with no apparent association with "use of ICU" or other categories. Other associations identified were "lower costs" and "no displacement of the patient," "female," "age between 56 and 75 years," "death within 30 days," and "death within 1 year". CONCLUSIONS: The nonclustered characteristic of the most serious cases and the association between "deaths" and "lower costs" suggests that the technological resources available during hospitalization for AMI are not being properly used.

RESUMEN

RESUMO: Introdução: O cenário epidemiológico mundial revela um crescimento das doenças cardiovasculares, no qual se destaca o infarto agudo do miocárdio (IAM), devido à sua grande magnitude e severidade. No Brasil, doenças coronarianas representam já cerca de 5% dos gastos com internação hospitalar. Objetivo: Caracterizar as internações dos pacientes do Sistema Único de Saúde (SUS) por IAM por meio da identificação de agrupamentos sugeridos por uma análise de agrupamentos tradicional e por uma análise de correspondência múltipla (ACM). Métodos: Registros do Sistema de Internações Hospitalares (SIH/SUS) com diagnóstico principal de IAM, no Estado do Rio de Janeiro, 2002, foram selecionados e posteriormente relacionados aos do Sistema de Informações sobre Mortalidade (SIM/SUS). A seguir, uma ACM e uma métrica chamada distância de tolerância foram utilizadas para a identificação de clusters , sendo a variável de interesse "gastos com internação" classificada em duas categorias (acima e abaixo de R$ 905,00). Resultados: Foi possível associar "maiores gastos" com "utilização de Centro de Tratamento Intensivo (CTI)" e com "gravidade moderada do caso", e "menores gastos" com "gravidade leve" e "não utilização de CTI". Por outro lado, casos de alta gravidade apresentaram-se isolados, sem associação com CTI ou outras variáveis. Também foi detectada associação entre a categoria "menores gastos" e as categorias: "não deslocamento do paciente", "sexo feminino", "idade entre 56 e 75 anos", "óbito até 30 dias" e "óbito até 1 ano". Conclusão: o aspecto isolado dos casos de maior gravidade e a associação entre "óbitos" e "menores gastos" sugere que os recursos tecnológicos disponíveis durante a internação por IAM não estão sendo adequadamente empregados.

RESUMEN

BACKGROUND: Prior to implementation of a national surveillance system for cardiovascular disease in Barbados, a small island state with limited health resources, the national burden of acute myocardial infarction (MI) was unknown. METHODS: We retrospectively estimated national acute MI incidence rates (IRs) per 100,000 during the decade before registry implementation (1999-2008), using easily accessible routine data from different sources, assessing changes over time through Poisson regression. Future events (2009-2013) were estimated using simple sensitivity analysis to incorporate prediction uncertainty. Model predictions were compared with actual IRs from initial years of the registry. RESULTS: In 2000, crude IR was 85.5 (95% CI: 74.9-97.2), rising to 92.1 (81.2-103.9) in 2008. Accounting for population ageing, the model anticipated IR of 115.9 in 2010 (99.7-132.1), vs actual crude IR 129.7 (115.9-144.6). CONCLUSIONS: Despite no electronic medical record system in Barbados, data were simple to collect, and provided a rough baseline for acute MI burden. We show that, in countries with small populations, limited resources and in absence of surveillance, national mortality statistics and routine hospital data can be combined to adequately model national estimates of acute MI incidence. This cheap and simple, yet fairly accurate method could be a key tool for other low-resource countries with ageing populations and increasing cardiovascular disease levels.

RESUMEN

Pese a que la efectividad de los programas de prevención secundaria en pacientes con enfermedades cardiovasculares (ECV) ha sido ampliamente demostrada, su implementación tanto Chile como a nivel internacional ha sido pobre. Objetivo: Determinar la tasa costo-efectividad de una propuesta teórica de Programa de Rehabilitación cardiovascular (PRC) basada en la evidencia y validada por expertos, en personas post Infarto Agudo al Miocardio (IAM) en el nivel secundario de atención en salud, pertenecientes al Servicio de Salud Metropolitano Norte, Región Metropolitana. Método: Se elaboró un protocolo teórico de un PRC integral basado en las guías clínicas internacionales (AHA, AACVPD, NICE, ESC, NHMRC, Victoria), ajustado a la realidad chilena, el cual fue costeado. Luego se estimó los años de vida por muerte prematura con y sin participación en un PRC, para obtener finalmente los Años de Vida Ganados (AVG). Con ello se calculó la tasa de costo-efectividad. Resultados: El costo anual del centro de rehabilitación cardíaca es de $64.407.065 CLP. La Razón Incremental de Costo Efectividad (ICER), considerando una reducción de la mortalidad tardía del 25%, es de CLP$475.209,72/AVG. Valor que al ser menor al Producto Interno Bruto per cápita, se considera como una intervención muy costo efectiva. Conclusión: Un programa de rehabilitación cardiaca integral post-IAM parece muy costo-efectivo.

Although the effectiveness of secondary prevention programs in patients with cardiovascular disease (CVD) has been widely demons-trated, its implementation both in Chile and other countries has been scarce. Aim: To determine the cost-effectiveness of an evidence-based theoretical comprehensive cardiac rehabilitation (CCR), validated by experts, for post-acute myocardial infarction (AMI) patients at the secondary level from the Chilean Public Health System. Methods: A theoretical protocol of a CCR program based on recommendations from international guidelines (AHA, AACVPD, NICE, ESC, NHMRC, Victoria) was elaborated and adjusted to the Chilean conditions. A cost analysis was performed. Life years due to premature death were estimated with and without participation in the cardiac rehabilitation program (CRP). We obtained gained life-years, and calculated the ratio of cost-effectiveness. Results: The annual cost of the cardiac rehabilitation center is $ 64,407,065 CLP. The Incremental Cost Effectiveness Ratio (ICER) considering a reduction in late mortality of 25%, is CLP$475.209,72/ AVG. Since it is less than one per capita gross domestic product, it is considered as a very cost-effective intervention. Conclusion: A comprehensive cardiac rehabilitation program post AMI is very cost-effective for use in a in public health service. It should be considered to review Optimal frequency and intensity of exercise in order to achieve optimal results should be determined.

RESUMEN

IMPORTANCE: It is unknown whether hospital transfer rates for patients with acute myocardial infarction admitted to nonprocedure hospitals (facilities that do not provide catheterization) vary and whether these rates further influence revascularization rates, length of stay, and mortality. OBJECTIVES: To examine hospital differences in transfer rates for elderly patients with acute myocardial infarction across nonprocedure hospitals and to determine whether these rates are associated with revascularization rates, length of stay, and mortality. DESIGN, SETTING, AND PARTICIPANTS: We used Medicare claims data from January 1, 2006, to December 31, 2008, to assess transfer rates in nonprocedure hospitals, stratified according to transfer rates as low (≤ 20%), mid-low (>20%-30%), mid-high (>30%-40%), or high (>40%). Data were analyzed for 55,962 Medicare fee-for-service patients admitted to 901 nonprocedure US hospitals with more than 25 admissions per year for acute myocardial infarction. MAIN OUTCOMES AND MEASURES: We compared rates of catheterization, percutaneous coronary intervention, and coronary artery bypass graft surgery during hospitalization and within 60 days, as well as hospital total length of stay, across groups. We measured risk-standardized mortality rates at 30 days and 1 year. RESULTS The median transfer rate was 29.4% (interquartile range [25th-75th percentile], 21.8%-37.8%). Higher transfer rates were associated with higher rates of catheterization (P < .001), percutaneous coronary intervention (P < .001), and coronary artery bypass graft surgery (P < .001). Median length of stay was not meaningfully different across the groups. There was no meaningful evidence of associations between transfer rates and risk-standardized mortality at 30 days (mean [SD], 22.3% [2.6%], 22.1% [2.3%], 22.3% [2.4%], and 21.7% [2.1%], respectively; P = .054) or 1 year (43.9% [2.3%], 43.6% [2.2%], 43.5% [2.4%], and 42.8% [2.2%], respectively; P < .001) for low, mid-low, mid-high, and high transfer groups. CONCLUSIONS AND RELEVANCE: Nonprocedure hospitals vary substantially in their use of the transfer process for elderly patients admitted with acute myocardial infarction. High-transfer hospitals had greater use of invasive cardiac procedures after admission compared with low-transfer hospitals. However, higher transfer rates were not associated with a significantly lower risk-standardized mortality rate at 30 days. Moreover, at 1 year there was only a 1.1% difference (42.8% vs 43.9%) between hospitals with higher and lower transfer rates. These findings suggest that, as a single intervention, promoting the transfer of patients admitted with acute myocardial infarction may not improve hospital outcomes.

RESUMEN

OBJECTIVE: To analyze the expenses of HIV/AIDS and acute myocardial infarction (AMI) treatment in Brazil. METHODS: A search in the Brazilian epidemiological database (DATASUS) on AMI and AIDS hospitalizations and their costs was done from January 1998 to December 2011. The number of HIV/AIDS cases and antiretroviral treatment (ART) costs was obtained from public Brazilian databases. RESULTS: In 5 years, HIV/AIDS cases increased 38.5%, mainly in patients aged 25-49. There were 180,640 patients in ART in 2007 at a cost of R$ 3,920 per patient/year. The hospitalizations due to AIDS were stable over the last 13 years; however, the hospitalizations due to AMI have increased 78%. In 2007, the expenses with hospitalizations for HIV/AIDS and AMI (25-49 years) were approximately 0.12 and 1.52% of the Ministry of Health budget allocated to reimburse inpatient costs. The expenses on ART totaled 1.5% of the total budget (all age groups). CONCLUSION: The prevalence of HIV/AIDS is still increasing in Brazil. There are scientific evidences suggesting an increased incidence of AIM in this population. Considering the high costs for the treatment of both diseases, an economic analysis is important to alert health managers to strengthen the preventive measures to guarantee the financial sustainability of such treatment.

RESUMEN

OBJECTIVE: To present the methodology and the results of a field survey to assess the chain costs of procedures for treatment of acute myocardial infarction (AMI), carried out in 11 Brazilian reference and specialized hospitals. METHODS: The cost assessment used the cost per procedure and per pathology systems. The procedures associated with the treatment of AMI were organized and their logical sequence (protocols) was used to create a flowchart. Data collection tools gathered information on prices and quantities in 2008 (private, health insurance, SUS, and Brazilian Medical Association - AMB price lists), as well as the applicable costs. RESULTS: Overall, the total cost of the procedures involving the 'standard treatment' of AMI was R$ 12,873.69, if percutaneous coronary intervention (PCI) did not involve stent use. If the stent becomes necessary, the cost increases to R$ 23,461.87. CONCLUSION: Among the results, we emphasize the fact that the costs of the more expensive procedures did not present statistically significant variations between hospitals, regardless of their location, predominant clientele or legal nature, and the fact that hospitals that treat predominantly users of the Brazilian Unified Health System registered the lowest costs, albeit not statistically significant regarding the entire chain of procedures associated with the pathology.

RESUMEN

OBJETIVO: Apresenta a metodologia e os resultados de uma pesquisa de campo para avaliar os custos da cadeia de procedimentos para tratamento do Infarto Agudo do Miocárdio (IAM), realizada em 11 hospitais brasileiros de excelência e especializados. MÉTODOS: A apuração do custo utilizou o sistema de custo por procedimento e o sistema por patologia. Os procedimentos associados ao tratamento do IAM foram organizados com sua sequência lógica (protocolos), dando origem a um fluxograma. Os instrumentos de coleta da pesquisa contemplavam informações relativas aos preços e as quantidades (particular, convênios, tabela SUS e Associação Médica Brasileira - AMB), praticados no ano de 2008, bem como os custos pertinentes. RESULTADOS: De forma geral, o custo total dos procedimentos que integram o "tratamento-padrão" do IAM, totalizou R$ 12.873,69 se a intervenção coronária percutânea (ICP) não envolver utilização de stent. Caso este se torne necessário, o custo se eleva para R$ 23.461,87. CONCLUSÃO: Entre os resultados obtidos destacam-se: o fato de os valores dos procedimentos mais caros não apresentarem variações estatísticas significativas entre os hospitais, independentemente de sua localização, clientela predominante ou natureza jurídica; e o fato de os hospitais, que tratam predominantemente de usuários do Sistema Único de Saúde, registrar custos menores, mas não estatisticamente significativos, para toda a cadeia de procedimentos associada à patologia.
