- 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, RobertoBackground-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, 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.
- Accuracy of Myocardial Biomarkers in the Diagnosis of Myocardial Infarction After Revascularization as Assessed by Cardiac Resonance: The Medicine, Angioplasty, Surgery Study V (MASS-V) Trial(2016) HUEB, Whady; GERSH, Bernard J.; COSTA, Leandro Menezes Alves da; OIKAWA, Fernando Teiichi Costa; MELO, Rodrigo Morel Vieira de; REZENDE, Paulo Cury; GARZILLO, Cibele Larrosa; LIMA, Eduardo Gomes; NOMURA, Cesar Higa; VILLA, Alexandre Volney; HUEB, Alexandre Ciappina; STRUNZ, Celia Maria Cassaro; FAVARATO, Desiderio; TAKIUTI, Myrthes Emy; ALBUQUERQUE, Cicero Piva de; SILVA, Expedito Eustaquio Ribeiro da; RAMIRES, Jose Antonio Franchini; KALIL FILHO, RobertoBackground. The lack of a correlation between myocardial necrosis biomarkers and electrocardiographic abnormalities after revascularization procedures has resulted in a change in the myocardial infarction (MI) definition. Methods. Patients with stable multivessel disease who underwent percutaneous or surgical revascularization were included. Electrocardiograms and concentrations of high-sensitive cardiac troponin I (cTnI) and creatine kinase (CK)-MB were assessed before and after procedures. Cardiac magnetic resonance and late gadolinium enhancement were performed before and after procedures. MI was defined as more than five times the 99th percentile upper reference limit for cTnI and 10 times for CK-MB in percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), respectively, and new late gadolinium enhancement for cardiac magnetic resonance. Results. Of the 202 patients studied, 69 (34.1%) underwent on-pump CABG, 67 (33.2%) off-pump CABG, and 66 (32.7%) PCI. The receiver operating characteristic curve showed the accuracy of cTnI for on-pump CABG, off-pump CABG, and PCI patients was 21.7%, 28.3%, and 52.4% and for CK-MB was 72.5%, 81.2%, and 90.5%, respectively. The specificity of cTnI was 3.6%, 9.4%, and 42.1% and of CK-MB was 73.2%, 86.8%, and 96.4%, respectively. Sensitivity of cTnI was 100%, 100%, and 100% and of CK-MB was 69.2%, 64.3%, and 44.4%, respectively. The best cutoff of cTnI for on-pump CABG, off-pump CABG, and PCI was 6.5 ng/mL, 4.5 ng/mL, and 4.5 ng/mL (162.5, 112.5, and 112.5 times the 99th percentile upper reference limit) and of CK-MB was 37.5 ng/mL, 22.5 ng/mL, and 11.5 ng/mL (8.5, 5.1, and 2.6 times the 99th percentile upper reference limit), respectively. Conclusions. Compared with cardiac magnetic resonance, CK-MB was more accurate than cTnI for diagnosing MI. These data suggest a higher troponin cutoff for the diagnosis of procedure-related MI.

- Hypotheses, rationale, design, and methods for evaluation of ischemic preconditioning assessed by sequential exercise tests in diabetic and non-diabetic patients with stable coronary artery disease - a prospective study(2013) REZENDE, Paulo Cury; GARCIA, Rosa Maria Rahmi; UCHIDA, Augusto Hiroshi; COSTA, Leandro Menezes Alves; SCUDELER, Thiago Luis; MELO, Rodrigo Morel Vieira; OIKAWA, Fernando Teiichi Costa; GARZILLO, Cibele Larrosa; LIMA, Eduardo Gomes; SEGRE, Carlos Alexandre Wainrober; FAVARATO, Desiderio; GIRARDI, Priscyla; TAKIUTI, Myrthes; STRUNZ, Celia Cassaro; HUEB, Whady; RAMIRES, Jose Antonio Franchini; KALIL FILHO, RobertoBackground: Ischemic preconditioning is a powerful mechanism of myocardial protection and in humans it can be evaluated by sequential exercise tests. Coronary Artery Disease in the presence of diabetes mellitus may be associated with worse outcomes. In addition, some studies have shown that diabetes interferes negatively with the development of ischemic preconditioning. However, it is still unknown whether diabetes may influence the expression of ischemic preconditioning in patients with stable multivessel coronary artery disease. Methods/Design: This study will include 140 diabetic and non-diabetic patients with chronic, stable coronary artery disease and preserved left ventricular systolic function. The patients will be submitted to two sequential exercise tests with 30-minutes interval between them. Ischemic parameters will be compared between diabetic and non-diabetic patients. Ischemic preconditioning will be considered present when time to 1.0 mm ST-segment deviation is greater in the second of two sequential exercise tests. Exercise tests will be analyzed by two independent cardiologists. Discussion: Ischemic preconditioning was first demonstrated by Murry et al. in dog's hearts. Its work was reproduced by other authors, clearly demonstrating that brief periods of myocardial ischemia followed by reperfusion triggers cardioprotective mechanisms against subsequent and severe ischemia. On the other hand, the demonstration of ischemic preconditioning in humans requires the presence of clinical symptoms or physiological changes difficult to be measured. One methodology largely accepted are the sequential exercise tests, in which, the improvement in the time to 1.0 mm ST depression in the second of two sequential tests is considered manifestation of ischemic preconditioning. Diabetes is an important and independent determinant of clinical prognosis. It's a major risk factor for coronary artery disease. Furthermore, the association of diabetes with stable coronary artery disease imposes worse prognosis, irrespective of treatment strategy. It's still not clearly known the mechanisms responsible by these worse outcomes. Impairment in the mechanisms of ischemic preconditioning may be one major cause of this worse prognosis, but, in the clinical setting, this is not known. The present study aims to evaluate how diabetes mellitus interferes with ischemic preconditioning in patients with stable, multivessel coronary artery disease and preserved systolic ventricular function.
- 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.

- Chronic troponin elevation assessed by myocardial T1 mapping in patients with stable coronary artery disease(2023) SEGRE, Carlos Alexandre W.; LEMOS, James A. de; ASSUNCAO, Antonildes Nascimento; NOMURA, Cesar Higa; FAVARATO, Desiderio; STRUNZ, Celia Maria Cassaro; VILLA, Alexandre Volney; PARGA FILHO, Jose Rodrigues; REZENDE, Paulo Cury; HUEB, Whady; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto; SERRANO, Carlos VicenteBackground:Cardiac troponin detected with sensitive assays can be chronically elevated, in the absence of unstable coronary syndromes. In patients with chronic coronary artery disease, clinically silent ischemic episodes may cause chronic troponin release. T1 mapping is a cardiovascular magnetic resonance technique useful in quantitative cardiac tissue characterization. We selected patients with anatomically and functionally normal hearts to investigate associations between chronic troponin release and myocardial tissue characteristics assessed by T1 mapping. Methods:We investigated the relationship between cardiac troponin I concentrations and cardiovascular magnetic resonance T1 mapping parameters in patients with stable coronary artery disease enrolled in MASS V study before elective revascularization. Participants had no previous myocardial infarction, negative late gadolinium enhancement, normal left ventricular function, chamber dimensions and wall thickness. Results:A total of 56 patients were analyzed in troponin tertiles: nativeT1 and extracellular volume (ECV) values (expressed as means +/- standard deviations) increased across tertiles: nativeT1 (1006 +/- 27 ms vs 1016 +/- 27 ms vs 1034 +/- 37 ms, ptrend = 0.006) and ECV (22 +/- 3% vs 23 +/- 1.9% vs 25 +/- 3%, ptrend = 0.007). Cardiac troponin I concentrations correlated with native T1(R = 0.33, P = .012) and ECV (R = 0.3, P = .025), and were independently associated with nativeT1 (P = .049) and ventricular mass index (P = .041) in multivariable analysis. Conclusion:In patients with chronic coronary artery disease and structurally normal hearts, troponin I concentrations correlated with T1 mapping parameters, suggesting that diffuse edema or fibrosis scattered in normal myocardium might be associated with chronic troponin release.
conferenceObject LIPID TRANSFER TO HIGH DENSITY LIPOPROTEINS IN TYPE 2 DIABETIC PATIENTS WITH AND WITHOUT CORONARY ARTERY DISEASE(2012) SPRANDEL, Marilia C. O.; HUEB, Whady; CASELLA-FILHO, Antonio; SEGRE, Alexandre; REZENDE, Paulo Cury; CARVALHO, Ana L. O.; FAVARATO, Desiderio; MARANHAO, Raul C.; RAMIRES, Jose; KALIL-FILHO, RobertoBackground In type 2 diabetes mellitus (DM2), HDL-cholesterol is diminished and it is important to understand the functional and metabolic changes existing in HDL in DM2 patients that may predispose to coronary artery disease (CAD). Lipid transfers between HDL and the other lipoproteins, mediated by cholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP), are crucial steps in HDL formation and role in reverse cholesterol transfer. Objective Investigate whether development of CAD in DM2 patients are associated with alterations in lipid transfers to HDL and in content of free cholesterol in the plasma. Methods 78 patients with DM2 and CAD (DM2-CAD) and 78 with DM2 without CAD, as diagnosed by cineangiography, were studied. They were of both genders, aged 40-80 yrs. Plasma was incubated for 1h at 37oC with a donor nanoemulsion labeled with 3H -cholesteryl-esters and14C -phospholipids or with 14C-free-cholesterol and 3H -triglycerides. Radioactive lipids transferred from the donor nanoemulsion to HDL were measured in the supernatant after chemical precipitation of non-HDL fractions and the nanoemulsion. Results are % of the total radioactivity of each lipid in HDL. Results In DM2-CAD, LDL-cholesterol and triglycerides were higher than in DM2; HDL-cholesterol was lower. Compared to DM2, DM2-CAD showed diminished transfer to HDL of free-cholesterol (DM2-CAD=4.23±0.24; DM2= 5.66±0.14, p<0.0001) and of triglycerides (1.65±0.13 vs 3.08±0.11, p<0.0001), whereas cholesteryl-ester transfer was increased (3.67±0.16 vs 2.25±0.13, p<0.0001); phospholipid transfer was equal (15.37±0.60 vs15.18±0.20, p=0.76). CETP concentration was equal, while plasma free-cholesterol was higher in DM2-CAD (DM2-CAD=36.9±0.9; DM2=33.1±0.7, p=0.003).HDL particle diameter was equal in both groups. Conclusion The reduction of free-cholesterol transfer to HDL may hinder cholesterol esterification and reverse cholesterol transport. Alterations in triglyceride and cholesteryl-ester transfer may affect lipoprotein stability. Those disturbances in HDL metabolism may facilitate CAD development in DM2.

Prevention: Clinical Presentation Number: 911-8- Troponin in diabetic patients with and without chronic coronary artery disease(2015) SEGRE, Carlos Alexandre Wainrober; HUEB, Whady; GARCIA, Rosa Maria Rahmi; REZENDE, Paulo Cury; FAVARATO, Desiderio; STRUNZ, Celia Maria Cassaro; SPRANDEL, Marilia da Costa Oliveira; ROGGERIO, Alessandra; CARVALHO, Ana Luiza de Oliveira; MARANHAO, Raul Cavalcante; RAMIRES, Jose Antonio Franchini; KALIL FILHO, RobertoBackground: Cardiac-specific troponin detected with the new high-sensitivity assays can be chronically elevated in response to cardiovascular comorbidities and confer important prognostic information, in the absence of unstable coronary syndromes. Both diabetes mellitus and coronary artery disease are known predictors of troponin elevation. It is not known whether diabetic patients with coronary artery disease have different levels of troponin compared with diabetic patients with normal coronary arteries. To investigate this question, we determined the concentrations of a level 1 troponin assay in two groups of diabetic patients: those with multivessel coronary artery disease and those with angiographically normal coronary arteries. Methods: We studied 95 diabetic patients and compared troponin in serum samples from 50 patients with coronary artery disease (mean age = 63.7, 58 % male) with 45 controls with angiographically normal coronary arteries. Brain natriuretic peptide and the oxidative stress biomarkers myeloperoxidase, nitrotyrosine and oxidized LDL were also determined. Results: Diabetic patients with coronary artery disease had higher levels of troponin than did controls (median values, 12.0 pg/mL (95 % CI:10-16) vs 7.0 pg/mL (95 % CI: 5.9-8.5), respectively; p = 0.0001). The area under the ROC curve for the diagnosis of CAD was 0.712 with a sensitivity of 70 % and a specificity of 66 %. Plasma BNP levels and oxidative stress variables (myeloperoxidase, nitrotyrosine, and oxidized LDL) were not different between the two groups. In a multivariate analysis, gender (p = 0.04), serum glucose (0.03) and Troponin I (p = 0.01) had independent statistical significance. Conclusion: Troponin elevation is related to the presence of chronic coronary artery disease in diabetic patients with multiple associated cardiovascular risk factors. Troponin may serve as a biomarker in this high-risk population.
conferenceObject PERFORMANCE OF LEFT VENTRICULAR EJECTION FRACTION ON PATIENTS WITH STABLE MULTIVESSEL CORONARY DISEASE SUBMITTED TO MEDICINE, ANGIOPLASTY OR SURGERY: 10 YEARS FOLLOW-UPFROM MASS II TRIAL(2012) GARZILLO, Cibele L.; HUEB, Whady; LIMA, Eduardo Gomes; REZENDE, Paulo Cury; FAVARATO, Desiderio; SOARES, Paulo; HUEB, Alexandre Ciappina; STOLF, Noedir A. G.; RAMIRES, Jose; KALIL-FILHO, RobertoBackground Coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are assumed as effective therapeutic options for the protection of the ischemic myocardium. However, it is not established if those procedures are effective for left ventricular ejection fraction (LVEF) preservation. In this setting, we evaluated the evolution of LVEF in patients with stable multivessel coronary disease, submitted to CABG, PCI or medical treatment (MT) alone, after ten years of follow-up. Methods Echocardiography was performed on patients participants of MASS II trial, previously to randomization for CABG, PCI or MT, and after 10 years. LVEF was measured by the biplane method (Simpson), when regional wall-motion abnormalities were present, or by the Teichholz method. Results After a follow-up of 10.32 (±1.43) years, 350 patients had LVEF reassessed: 108 patients on MT, 111 on CABG and 131 on PCI group. Main baseline characteristics and the occurrence of AMI were similar among the three groups. There was no difference of LVEF either at the beginning (0.61 + 0.07, 0.61 + 0.08 e 0.61 + 0.09 respectively for PCI, CABG and MT, p=0.675) and the end of follow up (0.56 + 0.11, 0.55 + 0.11 e 0.55 + 0.12 respectively for PCI, CABG and MT, p=0.675). The impact of other variables over LVEF evolution, such as gender, age, diabetes and arterial pattern, were also analyzed, and no relevance was demonstrated. However, the presence of previous AMI (OR 2.50, 95% CI 1.40-4.45; p= 0.0007) and the occurrence of AMI during follow up (OR 2.73, 95% IC 1.25-5.92; p=0.005) were associated with an increased risk of developing LVEF < 45%. Also, AMI during follow-up was responsible for a greater reduction of LVEF (reduction delta of 18.29 ± 21.22% and 6.63 ± 18.91%, respectively for patients with and without AMI, p=0.001). Conclusion Thus, compared with PCI or CABG patients, patients in the medical group with unprotected coronary artery disease by mechanical revascularization without adverse cardiac events showed no differences in the left ventricular function after 10 years of follow up. Moreover, whatever of interventional therapeutic strategies applied, the left ventricular function remained unchanged in absence of MACE.
