    Cost-Effectiveness Analysis for Surgical, Angioplasty, or Medical Therapeutics for Coronary Artery Disease 5-Year Follow-Up of Medicine, Angioplasty, or Surgery Study (MASS) II Trial
    (2012) VIEIRA, Ricardo D'Oliveira; HUEB, Whady; HLATKY, Mark; FAVARATO, Desiderio; REZENDE, Paulo Cury; GARZILLO, Cibele Larrosa; LIMA, Eduardo Gomes; SOARES, Paulo Rogerio; HUEB, Alexandre Ciappina; PEREIRA, Alexandre Costa; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Background-The Second Medicine, Angioplasty, or Surgery Study (MASS II) included patients with multivessel coronary artery disease and normal systolic ventricular function. Patients underwent coronary artery bypass graft surgery (CABG, n = 203), percutaneous coronary intervention (PCI, n = 205), or medical treatment alone (MT, n = 203). This investigation compares the economic outcome at 5-year follow-up of the 3 therapeutic strategies. Methods and Results-We analyzed cumulative costs during a 5-year follow-up period. To analyze the cost-effectiveness, adjustment was made on the cumulative costs for average event-free time and angina-free proportion. Respectively, for event-free survival and event plus angina-free survival, MT presented 3.79 quality-adjusted life-years and 2.07 quality-adjusted life-years; PCI presented 3.59 and 2.77 quality-adjusted life-years; and CABG demonstrated 4.4 and 2.81 quality-adjusted life-years. The event-free costs were $9071.00 for MT; $19 967.00 for PCI; and $18 263.00 for CABG. The paired comparison of the event-free costs showed that there was a significant difference favoring MT versus PCI (P<0.01) and versus CABG (P<0.01) and CABG versus PCI (P<0.01). The event-free plus angina-free costs were $16 553.00, $25 831.00, and $24 614.00, respectively. The paired comparison of the event-free plus angina-free costs showed that there was a significant difference favoring MT versus PCI (P=0.04), and versus CABG (P<0.001); there was no difference between CABG and PCI (P>0.05). Conclusions-In the long-term economic analysis, for the prevention of a composite primary end point, MT was more cost effective than CABG, and CABG was more cost-effective than PCI.

    Long-term analysis of left ventricular ejection fraction in patients with stable multivessel coronary disease undergoing medicine, angioplasty or surgery: 10-year follow-up of the MASS II trial
    (2013) GARZILLO, Cibele Larrosa; HUEB, Whady; GERSH, Bernard J.; LIMA, Eduardo Gomes; REZENDE, Paulo Cury; HUEB, Alexandre Ciappina; VIEIRA, Ricardo D'Oliveira; FAVARATO, Desiderio; PEREIRA, Alexandre Costa; SOARES, Paulo Rogerio; SERRANO JR., Carlos Vicente; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Background Assuming that coronary interventions, both coronary bypass surgery (CABG) and percutaneous coronary intervention (PCI), are directed to preserve left ventricular function, it is not known whether medical therapy alone (MT) can achieve this protection. Thus, we evaluated the evolution of LV ejection fraction (LVEF) in patients with stable coronary artery disease (CAD) treated by CABG, PCI, or MT as a post hoc analysis of a randomized controlled trial with a follow-up of 10 years. Methods Left ventricle ejection fraction was assessed with transthoracic echocardiography in patients with multivessel CAD, participants of the MASS II trial before randomization to CABG, PCI, or MT, and re-evaluated after 10 years of follow-up. Results Of the 611 patients, 422 were alive after 10.32 1.43 years. Three hundred and fifty had LVEF reassessed: 108 patients from MT, 111 from CABG, and 131 from PCI. There was no difference in LVEF at the beginning (0.61 0.07, 0.61 0.08, 0.61 0.09, respectively, for PCI, CABG, and MT, P 0.675) or at the end of follow-up (0.56 0.11, 0.55 0.11, 0.55 0.12, P 0.675), or in the decline of LVEF (reduction delta of 7.2 17.13, 9.08 18.77, and 7.54 22.74). Acute myocardial infarction (AMI) during the follow-up was associated with greater reduction in LVEF. The presence of previous AMI (OR: 2.50, 95 CI: 1.404.45; P 0.0007) and during the follow-up (OR: 2.73, 95 CI: 1.255.92; P 0.005) was associated with development of LVEF 45. Conclusion Regardless of the therapeutic option applied, LVEF remains preserved in the absence of a major adverse cardiac event after 10 years of follow-up.

    Impact of diabetes on 10-year outcomes of patients with multivessel coronary artery disease in the Medicine, Angioplasty, or Surgery Study II (MASS II) trial
    (2013) LIMA, Eduardo Gomes; HUEB, Whady; GARCIA, Rosa Maria Rahmi; PEREIRA, Alexandre Costa; SOARES, Paulo Rogerio; FAVARATO, Desiderio; GARZILLO, Cibele Larrosa; VIEIRA, Ricardo D'Oliveira; REZENDE, Paulo Cury; TAKIUTI, Myrthes; GIRARDI, Priscyla; HUEB, Alexandre Ciappina; RAMIRES, Jose A. F.; KALIL FILHO, Roberto
    Introduction Diabetes mellitus is a major cause of coronary artery disease (CAD). Despite improvement in the management of patients with stable CAD, diabetes remains a major cause of increased morbidity and mortality. There is no conclusive evidence that either modality is better than medical therapy alone for the treatment of stable multivessel CAD in patients with diabetes in a very long-term follow-up. Our aim was to compare 3 therapeutic strategies for stable multivessel CAD in a diabetic population and non-diabetic population. Methods It was compared medical therapy (MT), percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG) in 232 diabetic patients and 379 nondiabetic patients with multivessel CAD. Endpoints evaluated were overall and cardiac mortality. Results Patients (n = 611) were randomized to CABG (n = 203), PCI (n = 205), or MT (n = 203). In a 10-year follow-up, more deaths occurred among patients with diabetes than among patients without diabetes (P = .001) for overall mortality. In this follow-up, 10-year mortality rates were 32.3% and 23.2% for diabetics and non-diabetics respectively (P = .024). Regarding cardiac mortality, 10-year cardiac mortality rates were 19.4% and 12.7% respectively (P = .031). Considering only diabetic patients and stratifying this population by treatment option, we found mortality rates of 31.3% for PCI, 27.5% for CABG and 37.5% for MT (P = .015 for CABG vs MT) and cardiac mortality rates of 18.8%, 12.5% and 26.1% respectively (P = .005 for CABG vs MT). Conclusions/interpretation Among patients with stable multivessel CAD and preserved left ventricular ejection fraction, the 3 therapeutic regimens had high rates of overall and cardiac-related deaths among diabetic compared with nondiabetic patients. Moreover, better outcomes were observed in diabetic patients undergoing CABG compared to MT in relation to overall and cardiac mortality in a 10-year follow-up.

    Fatal adenoviral necrotizing bronchiolitis case in a post-cardiac surgery intensive care unit
    (2011) CASTELLI, Jussara Bianchi; SICILIANO, Rinaldo F.; VIEIRA, Ricardo D.; AIELLO, Vera D.; STRABELLI, Tania M. V.
    We report a case of a 67 year-old-male patient admitted to the intensive care unit in the post-coronary bypass surgery period who presented cardiogenic shock, acute renal failure and three episodes of sepsis, the latter with pulmonary distress at the 30th post-operative day. The patient expired within five days in spite of treatment with vancomycin, imipenem, colistimethate and amphotericin B. At autopsy severe adenovirus pneumonia was found. Viral pulmonary infections following cardiovascular surgery are uncommon. We highlight the importance of etiological diagnosis to a correct treatment approach.

    EVOLUTION OF VENTRICULAR FUNCTION IN PATIENTS WITH STABLE CORONARY ARTERY DISEASE SUBMITTED TO ON-PUMP OR OFF-PUMP CORONARY ARTERY BYPASS GRAFT IN MASS III TRIAL
    (2012) STASZKO, Kamila F.; HUEB, Whady; LIMA, Eduardo; BISELLI, Bruno; GARCIA, Rosa Maria Rahmi; VIEIRA, Ricardo D. O.; GARZILLO, Cibele Larrosa; PEREIRA, Alexandre Costa; HUEB, Alexandre Ciappina; REZENDE, Paulo Cury; CASELLA-FILHO, Antonio; RAMIRES, Jose; KALIL-FILHO, Roberto
    Background Ventricular function is a major determinant of prognosis in patients with coronary artery disease (CAD). Few data are available to assess the evolution of ventricular function among patients submitted to off-pump coronary artery bypass graft surgery (OPCAB). Purpose To compare the evolution of ventricular function in a long-term follow-up among patients with stable CAD submitted to OPCAB or On-Pump coronary artery bypass graft (ONCAB) Methods Patients with stable CAD and preserved systolic left ventricular function were randomized to OPCAB or ONCAB and followed for 5 years. Patients who undergone a new evaluation of ventricular function in this follow-up were studied. Left ventricular ejection fraction (LVEF) was assessed by echocardiogram. Results Of 308 patients randomized to OPCAB (n=155) or ONCAB (n=153), 91 had a new assessment of ventricular function by echocardiogram in a 5-year follow-up: 49 in ONCAB group and 42 in OPCAB group. In ONCAB group the initial and final mean of LVEF was respectively 59.85% and 56.16% (p=0.10). In OPCAB group the initial and final mean of LVEF was respectively 59.18 % and 56.07 (p=0.17). Conclusion There was no difference in the evolution of LVEF among patients with stable CAD randomized to ONCAB or OPCAB in a 5-year follow-up.

    Effect of Complete Revascularization on 10-Year Survival of Patients With Stable Multivessel Coronary Artery Disease MASS II Trial
    (2012) VIEIRA, Ricardo D'Oliveira; HUEB, Whady; GERSH, Bernard J.; LIMA, Eduardo Gomes; PEREIRA, Alexandre Costa; REZENDE, Paulo Cury; GARZILLO, Cibele Larrosa; HUEB, Alexandre Ciappina; FAVARATO, Desiderio; SOARES, Paulo Rogerio; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Background-The importance of complete revascularization remains unclear and contradictory. This current investigation compares the effect of complete revascularization on 10-year survival of patients with stable multivessel coronary artery disease (CAD) who were randomly assigned to percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). Methods and Results-This is a post hoc analysis of the Second Medicine, Angioplasty, or Surgery Study (MASS II), which is a randomized trial comparing treatments in patients with stable multivessel CAD, and preserved systolic ventricular function. We analyzed patients who underwent surgery (CABG) or stent angioplasty (PCI). The survival free of overall mortality of patients who underwent complete (CR) or incomplete revascularization (IR) was compared. Of the 408 patients randomly assigned to mechanical revascularization, 390 patients (95.6%) underwent the assigned treatment; complete revascularization was achieved in 224 patients (57.4%), 63.8% of those in the CABG group and 36.2% in the PCI group (P = 0.001). The IR group had more prior myocardial infarction than the CR group (56.2% X 39.2%, P = 0.01). During a 10-year follow-up, the survival free of cardiovascular mortality was significantly different among patients in the 2 groups (CR, 90.6% versus IR, 84.4%; P = 0.04). This was mainly driven by an increased cardiovascular specific mortality in individuals with incomplete revascularization submitted to PCI (P = 0.05). Conclusions-Our study suggests that in 10-year follow-up, CR compared with IR was associated with reduced cardiovascular mortality, especially due to a higher increase in cardiovascular-specific mortality in individuals submitted to PCI.

    IMPACT OF METABOLIC SYNDROME ON THE OUTCOME OF PATIENTS WITH STABLE CORONARY ARTERY DISEASE SUBMITTED TO DIFFERENT TYPES OF TREATMENT: 10-YEAR FOLLOW-UP OF THE MASS II STUDY
    (2012) LIMA, Eduardo Gomes; HUEB, Whady; GARCIA, Rosa Maria Rahmi; VIEIRA, Ricardo D. O.; GARZILLO, Cibele Larrosa; PEREIRA, Alexandre Costa; HUEB, Alexandre Ciappina; REZENDE, Paulo Cury; CASELLA-FILHO, Antonio; RAMIRES, Jose; KALIL-FILHO, Roberto
    Background Metabolic syndrome (MetS) is understood as a condition that promotes atherosclerosis and confers an additional risk of adverse cardiovascular events in patients with coronary artery disease. The prognosis of this syndrome in this subset of patients in a long term follow up is inconclusive. Objective Evaluate the impact of metabolic syndrome on cardiac death in patients with symptomatic chronic multivessel coronary artery disease. Methods Patients randomized in MASS II study submitted to coronary artery bypass graft (CABG), angioplasty (PCI) or medical treatment (MT) were evaluated for the presence of MetS and followed prospectively for 10 years. We evaluated the incidence of overall and cardiac death in this period. Results Criteria for MetS were fulfilled in 283 patients of 583 (54%) randomized to three therapeutic strategies. The presence of MetS, was associated with an increased cardiac related death in studied population. During a 10-year follow-up, the probability cardiac mortality free survival was significantly different among patients in the 2 groups (MetS = 81,6% × non-MetS = 91,3% P=0.004). Stratifying patients with MetS by therapeutic approach we identify a statistical difference in cardiac death free survival comparing interventional approaches (CABG and PCI) to MT: 82,4% for CABG; 86,2% for PCI and 75,9% for MT (P=0,003). Besides, there is a group with best prognosis: patients without MetS submitted to CABG presenting 98,7% of patients free of cardiac death in a 10-year follow-up. Conclusion MetS confers high rates of cardiac death in patients with stable coronary artery disease irrespective of therapeutic strategy used. In patients with MetS, interventional approaches (PCI or CABG) seem to confer more protection against cardiac death in a 10-year follow-up.

    Cancer-related deaths among different treatment options in chronic coronary artery disease: results of a 6-year follow-up of the MASS II study
    (2012) VIEIRA, Ricardo D.; PEREIRA, Alexandre C.; LIMA, Eduardo G.; GARZILLO, Cibele L.; REZENDE, Paulo Cury; FAVARATO, Desiderio; HUEB, Alexandre C.; GERSH, Bernard J.; RAMIRES, Jose A. F.; HUEB, Whady
    Introduction The primary end points of randomized clinical trials evaluating the outcome of therapeutic strategies for coronary artery disease (CAD) have included nonfatal acute myocardial infarction, the need for further revascularization, and overall mortality. Noncardiac causes of death may distort the interpretation of the long-term effects of coronary revascularization. Materials and methods This post-hoc analysis of the second Medicine, Angioplasty, or Surgery Study evaluates the cause of mortality of patients with multivessel CAD undergoing medical treatment, percutaneous coronary intervention, or surgical myocardial revascularization [coronary artery bypass graft surgery (CABG)] after a 6-year follow-up. Mortality was classified as cardiac and noncardiac death, and the causes of noncardiac death were reported. Results Patients were randomized into CABG and non-CABG groups (percutaneous coronary intervention plus medical treatment). No statistical differences were observed in overall mortality (P = 0.824). A significant difference in the distribution of causes of mortality was observed among the CABG and non-CABG groups (P = 0.003). In the CABG group, of the 203 randomized patients, the overall number of deaths was 34. Sixteen patients (47.1%) died of cardiac causes and 18 patients (52.9%) died of noncardiac causes. Of these, seven deaths (20.6%) were due to neoplasia. In the non-CABG group, comprising 408 patients, the overall number of deaths was 69. Fifty-three patients (77%) died of cardiac causes and 16 patients (23%) died of noncardiac causes. Only five deaths (7.2%) were due to neoplasia. Conclusion Different treatment options for multivessel coronary artery disease have similar overall mortality: CABG patients had the lowest incidence of cardiac death, but the highest incidence of noncardiac causes of death, and specifically a higher tendency toward cancer-related deaths.

    Hypotheses, rationale, design, and methods for prognostic evaluation of cardiac biomarker elevation after percutaneous and surgical revascularization in the absence of manifest myocardial infarction. A comparative analysis of biomarkers and cardiac magnetic resonance. The MASS-V Trial
    (2012) HUEB, Whady; GERSH, Bernard J.; REZENDE, Paulo Cury; GARZILLO, Cibele Larrosa; LIMA, Eduardo Gomes; VIEIRA, Ricardo D'Oliveira; GARCIA, Rosa Maria Rahmi; FAVARATO, Desiderio; SEGRE, Carlos Alexandre W.; PEREIRA, Alexandre Costa; SOARES, Paulo Rogerio; RIBEIRO, Expedito; LEMOS, Pedro; PERIN, Marco A.; STRUNZ, Celia Cassaro; DALLAN, Luis A. O.; JATENE, Fabio B.; STOLF, Noedir A. G.; HUEB, Alexandre Ciappina; DIAS, Ricardo; GAIOTTO, Fabio A.; COSTA, Leandro Menezes Alves da; OIKAWA, Fernando Teiichi Costa; MELO, Rodrigo Morel Vieira de; SERRANO JUNIOR, Carlos Vicente; AVILA, Luiz Francisco Rodrigues de; VILLA, Alexandre Volney; PARGA FILHO, Jose Rodrigues; NOMURA, Cesar; RAMIRES, Jose A. F.; KALIL FILHO, Roberto
    Background: Although the release of cardiac biomarkers after percutaneous (PCI) or surgical revascularization (CABG) is common, its prognostic significance is not known. Questions remain about the mechanisms and degree of correlation between the release, the volume of myocardial tissue loss, and the long-term significance. Delayed-enhancement of cardiac magnetic resonance (CMR) consistently quantifies areas of irreversible myocardial injury. To investigate the quantitative relationship between irreversible injury and cardiac biomarkers, we will evaluate the extent of irreversible injury in patients undergoing PCI and CABG and relate it to postprocedural modifications in cardiac biomarkers and long-term prognosis. Methods/Design: The study will include 150 patients with multivessel coronary artery disease (CAD) with left ventricle ejection fraction (LVEF) and a formal indication for CABG; 50 patients will undergo CABG with cardiopulmonary bypass (CPB); 50 patients with the same arterial and ventricular condition indicated for myocardial revascularization will undergo CABG without CPB; and another 50 patients with CAD and preserved ventricular function will undergo PCI using stents. All patients will undergo CMR before and after surgery or PCI. We will also evaluate the release of cardiac markers of necrosis immediately before and after each procedure. Primary outcome considered is overall death in a 5-year follow-up. Secondary outcomes are levels of CK-MB isoenzyme and I-Troponin in association with presence of myocardial fibrosis and systolic left ventricle dysfunction assessed by CMR. Discussion: The MASS-V Trial aims to establish reliable values for parameters of enzyme markers of myocardial necrosis in the absence of manifest myocardial infarction after mechanical interventions. The establishments of these indices have diagnostic value and clinical prognosis and therefore require relevant and different therapeutic measures. In daily practice, the inappropriate use of these necrosis markers has led to misdiagnosis and therefore wrong treatment. The appearance of a more sensitive tool such as CMR provides an unprecedented diagnostic accuracy of myocardial damage when correlated with necrosis enzyme markers. We aim to correlate laboratory data with imaging, thereby establishing more refined data on the presence or absence of irreversible myocardial injury after the procedure, either percutaneous or surgical, and this, with or without the use of cardiopulmonary bypass.
