conferenceObject Lifestyle in wine drinkers and abstemious: the relationship of coronary lesions, calcium score and risk factors(2012) MOCHIDUKY, Roberta I.; ROCHITTE, Carlos E.; FAVARATO, Desiderio; ALBUQUERQUE, Cicero P.; GONSALVES, Cibele Regina L.; LAURINDO, Francisco Rafael M.; HUEB, Whady A.; LUZ, Protasio DaIntroduction: Red wine (RW) protects the cardiovascular system but objective evidence based on coronary status is lacking. Objectives: To assess the effects of chronic RW consumption upon coronary lesion burden. Methods: We performed Coronary Computed Tomographic Angiography in 204 male subjects whose mean age was 58.95±7.3 years and related lesions to risk factors (RF). One hundred were chronic RW drinkers who consumed at least one glass of RW wine/day, 4 –5 times/week, in the last 5 years and 104 were abstemious. Results: RW drinkers consumed 25.78 gr alcohol/day vs 0 among abstemious; they also ingested more calories (2118.50kcal vs 1776.21kcal daily; p<0.01) mainly from saturated fats (22.98 g vs16.51g; p<0.05) than abstemious. Abstemious, however, ingested more fibers (22.73 gr vs17.49 gr; p<0.05). There were no significant differences regarding age, smoking, BMI, arterial hypertension, diabetes, LDL and triglycerides. Psychological factors including anxiety, depression and stress also were similar. However, plasma glucose was lower (97.5±18.3 mg% vs105.9±32.0 mg %; p<0.06) and HDL was higher (46.9±10.9 mg% vs 39.5±9.0 mg%;p<0.01) in RW drinkers compared to abstemious. Calcium score was higher on RW drinkers than in abstemious(144.43±362.2 vs 122.05±370.26; p<0.004). Lesions were classified as absent or 50%. Considering LM, ADA, RCA and Cx in proximal, median and distal portions, plus 3 marginal, 3 diagonal and 2 terminal RCA branches, 3672 segments were included in the analysis. There were no significant differences regarding lesions severity between groups, except for more frequent zero lesions in proximal Cx (86.3 x 71.4 %; p<0.016). Conclusion: Despite higher caloric intake and saturated fats, RW drinkers have similar coronary lesion burden; calcium score, however, was higher compared to abstemious. Higher HDL cholesterol as cribed to RW drinking and lower plasma glucose may have protective roles.- 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.
- Red wine and equivalent oral pharmacological doses of resveratrol delay vascular aging but do not extend life span in rats(2012) LUZ, Protasio L. da; TANAKA, Leonardo; BRUM, Patricia Chakur; DOURADO, Paulo Magno Martins; FAVARATO, Desiderio; KRIEGER, Jose Eduardo; LAURINDO, Francisco Rafael M.Objective: To investigate, in male Wistar rats, the effects of long-term moderate red wine (RW) consumption (equivalent to similar to 0.15 mg% resveratrol RS), or RS in low (L, 0.15 mg%) or high (H, 400 mg%) doses in chow. Background: Both RW and RS exhibit cardioprotection. RS extends lifespan in obese rats. It is unclear whether RW consumption or low-dose RS delay vascular aging and prolong life span in the absence of overt risk factors. Methods: Endpoints were aerobic performance, exercise capacity, aging biomarkers (p53,p16,p21, telomere length and telomerase activity in aortic homogenates), vascular reactivity. Data were compared with controls (C) given regular chow. Results: Expressions of p53 decreased similar to 50% similar to with RW and LRS (p < 0.05 vs. C), p16 by similar to 29% with RW (p < 0.05 vs. C) and p21 was unaltered. RW and LRS increased telomere length >6.5-fold vs. C, and telomerase activity increased with LRS and HRS. All treatments increased aerobic capacity (C 32.5 +/- 1.2, RW 38.7 + 1.7, LRS 38.5 + 1.6, HRS 38.3 + 1.8 mlO2 min(-1) kg(-1)), and RW or LRS also improved time of exercise tolerance vs. C (p < 0.05). Endothelium-dependent relaxation improved with all treatments vs. C. Life span, however, was unaltered with each treatment vs. C = 673 +/- 30 days, p = NS. Conclusions: RW and LRS can preserve vascular function indexes in normal rats, although not extending life span. These effects were translated into better aerobic performance and exercise capacity.
- Mortality due to Cardiovascular Diseases in Brazil and in the Metropolitan Region of Sao Paulo: A 2011 Update(2012) MANSUR, Antonio de Padua; FAVARATO, DesiderioBackground: Cardiovascular diseases (CVD) are the leading causes of death in our population. There was a progressive decrease in mortality due to CVD up to 2005. Objective: To update the trends in mortality from cardiovascular diseases in Brazil and in the metropolitan region of Sao Paulo (MRSP) from 1990 to 2009. Methods: Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. The risk of death was adjusted by the direct method, having as reference the world population in 2000. Results: There was a progressive decrease in the risk of death from ischemic heart disease (IHD) and stroke in Brazil and in the MRSP. From 1990 to 2009, there was a decrease in mortality from IHD and stroke in men and women in Brazil and in the MRSP. There was a greater reduction in mortality from IHD in men in the MRSP than in Brazil (36.24% vs. 23.35%, p <0.001) and in women in the MRSP (44.55% vs. 29.5%; p <0.001). The highest reduction in stroke mortality was observed in men in the MRSP, when compared to Brazil (42.43% vs. 34.9%, p = 0.036) and an equal reduction in women in the MRSP and in Brazil (42.98% vs. 36.15%, p = 0.082). The decrease in mortality was significant for all age groups. Conclusion: We observed a progressive decrease in mortality from CVD, IHD and stroke in Brazil and in the MRSP. In spite of this decrease, we still have high rates of mortality from these diseases. (Arq Bras Cardiol 2012;99(2):755-761)
conferenceObject Role of Hypoglycemic Agents on Ischemic Preconditioning in Diabetic Patients with Stable Multivessel Coronary Artery Disease(2012) GARCIA, Rosa M.; HUEB, Whady; UCHIDA, Augusto H.; REZENDE, Paulo C.; LIMA, Eduardo G.; GARZILLO, Cibele L.; SEGRE, Carlos A.; FAVARATO, Desiderio; RAMIRES, Jose A.; KALIL FILHO, RobertoconferenceObject Five years follow-up of on-pump versus off pump coronary artery bypass surgery in diabetic patients of the MASS III Trial(2012) COSTA, L. M. A.; GARZILLO, C. L.; REZENDE, P. C.; LIMA, E. G.; FAVARATO, D.; MELO, R. M. Vieira De; OIKAWA, F. T.; HUEB, W.; RAMIRES, J. A. F.; KALIL FILHO, R.Purpose: Diabetic patients represent one-third of coronary artery disease (CAD) patients, many of whom are treated with revascularization procedures. They are at increased risk, including long-term mortality, compared with non-diabetic patients. Few data are available on the effects of off-pump coronary artery bypass graft surgery (OPCAB) on cardiac events and long-term clinical outcomes in this population. Methods: MASS III is a single-center randomized trial that evaluate 308 patients with stable coronary artery disease and preserved ventricular function assigned for off-pump (n=155) or on-pump (n=153) CABG. The subgroup of 110 diabetic patients were randomly assigned to off pump CAB (n=56) and on-pump CAB (n=54). Primary composite end points were death, myocardial infarction, further revascularization (surgery or angioplasty), or stroke. Results: The two randomized groups were well-matched for major baseline demographic, clinical, and angiographic characteristics. After 5-year follow-up, the primary composite end point was not different between groups (event-free survival 83.7% x 93.7%, p= 0.15). Conclusions:In this analysis, off pump diabetic patients presented the same incidence of composite end-points compared with on-pump CABG.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: 911-8conferenceObject 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.

Chronic CAD/Stable Ischemic Heart Disease: Therapy Presentation Number: 1208-410- 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, RobertoBackground-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.
- 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.
