- 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, RobertoBackground 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, RobertoIntroduction 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.
- Impact of Chronic Kidney Disease on Long-Term Outcomes in Type 2 Diabetic Patients With Coronary Artery Disease on Surgical, Angioplasty, or Medical Treatment(2016) LIMA, Eduardo Gomes; HUEB, Whady; GERSH, Bernard J.; REZENDE, Paulo Cury; GARZILLO, Cibele Larrosa; FAVARATO, Desiderio; HUEB, Alexandre Ciappina; GARCIA, Rosa Maria Rahmi; RAMIRES, Jose Antonio Franchini; KALIL FILHO, RobertoBackground. Coronary artery disease (CAD) among patients with diabetes and chronic kidney disease (CKD) is not well studied, and the best treatment for this condition is not established. Our aim was to compare three therapeutic strategies for CAD in diabetic patients stratified by renal function. Methods. Patients with multivessel CAD that underwent coronary artery bypass graft (CABG), angioplasty (percutaneous coronary intervention [PCI]), or medical therapy alone (MT) were included. Data were analyzed according to glomerular filtration rate in three strata: normal (>90 mL/min), mild CKD (60 to 89 mL/min), and moderate CKD (30 to 59 mL/min). End points comprised overall rate of mortality, acute myocardial infarction, and need for additional revascularization. Results. Among patients with normal renal function (n = 270), 122 underwent CABG, 72 PCI, and 76 MT; among patients with mild CKD (n = 367), 167 underwent CABG, 92 PCI, and 108 MT; and among patients with moderate CKD (n = 126), 46 underwent CABG, 40 PCI, and 40 MT. Event-free survival was 80.4%, 75.7%, 67.5% for strata 1, 2, and 3, respectively (p = 0.037). Survival rates among patients with no, mild, and moderate CKD are 91.1%, 89.6%, and 76.2%, respectively (p = 0.001) (hazard ratio 0.69; 95% confidence interval 0.51 to 0.95; p = 0.024 for stratum 1 versus 3). We found no differences for overall number of deaths or acute myocardial infarctions irrespective of strata. The need of new revascularization was different in all strata, favoring CABG (p < 0.001, p < 0.001, and p = 0.029 for no, mild, and moderate CKD, respectively). Conclusions. Mortality rates were higher in patients with mild and moderate CKD. Higher event-free survival was observed in the CABG group among patients with no and mild CKD. Besides, CABG was associated with less need for new revascularization compared with PCI and MT in all renal function strata.

- 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, WhadyIntroduction 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.

- Ten-Year Follow-Up of Off-Pump and On-Pump Multivessel Coronary Artery Bypass Grafting: MASS III(2019) HUEB, Whady; REZENDE, Paulo Cury; GERSH, Bernard J.; SOARES, Paulo Rogerio; FAVARATO, Desiderio; LIMA, Eduardo Gomes; GARZILLO, Cibele Larrosa; JATENE, Fabio B.; RAMIRES, Jose Antonio Franchini; KALIL FILHO, RobertoIt was a randomized trial, and 308 patients undergoing revascularization were randomly assigned: 155 to off-pump coronary artery bypass (OPCAB) and 153 to on-pump coronary artery bypass (ONCAB). End points were freedom from death, myocardial infarction, revascularization, and cerebrovascular accidents. The rates for 10-year, event-free survival for ONCAB versus OPCAB were 69.6% and 64%, (hazard ratio [HR]: 0.88; 95% confidence interval [CI] 0.86-1.02; P = .41), respectively. Adjusted Cox proportional hazard ratio was similar (HR: 0.92; 95% CI 0.61-1.38, P = .68). A difference occurred between the duration of OPCAB and ONCAB, respectively (4.9 +/- 1.5 vs 6.6 +/- 1.1 h, P < .001). Statistical differences occurred between OPCAB and ONCAB in the length of intensive care unit (ICU) stay (20 +/- 2.5 vs 48 +/- 10 hours, P < .001), time to extubation (5.5 +/- 4.2 vs 10.2 +/- 3.5 hours, P < .001), hospital stay (6.7 +/- 1.4 vs 9.2 +/- 1.3 days, P < .001), higher incidence of atrial fibrillation (AF; 33 vs 5 patients, P < .001), and blood requirements (46 vs 64 patients, P < .001). Grafts per patient was higher in ONCAB (3.15 vs 2.55 grafts, P < .001). No difference existed between the groups in primary composite end points at 10-year follow-up. Although OPCAB surgery was related to a lower number of grafts and higher incidence of AF, it had no effects related to long-term outcomes.
- Association Between Stress Testing-Induced Myocardial Ischemia and Clinical Events in Patients With Multivessel Coronary Artery Disease(2019) GARZILLO, Cibele Larrosa; HUEB, Whady; GERSH, Bernard; REZENDE, Paulo Cury; LIMA, Eduardo Gomes; FAVARATO, Desiderio; RAMIRES, Jose Antonio Franchini; KALIL FILHO, RobertoIMPORTANCE The long-term prognostic implications of myocardial ischemia documented during stress testing in patients with multivessel coronary artery disease (CAD) are unclear. OBJECTIVE To assess whether documented stress testing-induced myocardial ischemia is associated with major adverse cardiovascular events or ventricular function changes in patients with stable multivessel CAD. DESIGN, SETTING, AND PARTICIPANTS A prospective cohort study was conducted using data from a single-center randomized clinical trial (Medicine, Angioplasty, or Surgery Study [MASS] II) to examine the association of myocardial ischemia documented during stress testing at baseline with cardiovascular events and ventricular function changes during follow-up. Participants were previously randomized (May 1, 1995, to May 31, 2000) to medical therapy, percutaneous coronary intervention with bare metal stents, or coronary artery bypass grafting. Event-free survival was estimated by the Kaplan-Meier method, and multivariable Cox regression models were calculated to assess the association between ischemia and the primary composite end point. The vital status was determined on February 28, 2011. Data were analyzed from February 1, 2016, to April 1, 2017. MAIN OUTCOMES AND MEASURES Cardiovascular events (overall mortality, myocardial infarction, and revascularization for refractory angina) were tracked from the time of randomization to the end of the 10-year follow-up (mean [SD] duration, 11.4 [4.3] years). Myocardial ischemia was assessed at baseline and at 1-year intervals by exercise stress testing, and ventricular function (left ventricular ejection fraction) was assessed by echocardiography at baseline and after 10 years. Patients with documented ischemia were compared with those without ischemia regarding the outcomes and changes in ventricular function. RESULTS Of 611 participants, 535 underwent exercise stress testing at baseline: 270 with documented ischemia and 265 without. Of these 535 patients, 373 (69.7%) were men, and the mean (SD) age for the entire cohort was 59.7 (9.2) years. No association was found between the presence of ischemia at baseline and survival free of combined cardiovascular events (hazard ratio, 1.00; 95% CI, 0.80-1.27; P = .95) after multivariable adjustment that included CAD initial randomized treatments. In addition, among 320 patients who underwent echocardiographic evaluation, the slight decline in left ventricular ejection fraction after 10 years was similar in both groups (median [SD] difference, -4.9% [18.7%] vs -6.6% [20.0%], respectively, for groups with and without ischemia; P = .97). CONCLUSIONS AND RELEVANCE In this study, regardless of the therapeutic strategy applied, the presence of documented myocardial ischemia did not appear to be associated with an increased occurrence of major adverse cardiovascular events or changes in ventricular function in patients with multivessel CAD during a long-term follow-up.
