    Long Term Follow-Up of Drug Eluting Versus Bare Metal Stents in the Treatment of Saphenous Vein Graft Lesions
    (2013) YBARRA, Luiz F.; RIBEIRO, Henrique B.; POZETTI, Antonio H.; CAMPOS, Carlos A.; ESPER, Rodrigo B.; LEMOS, Pedro A.; LOPES, Augusto C.; KALIL-FILHO, Roberto; ELLIS, Stephen G.; RIBEIRO, Expedito E.
    Introduction: The safety and effectiveness of drug-eluting stent (DES) compared with bare metal stents (BMS) for the treatment of saphenous vein graft (SVG) disease is controversial, especially because of the lack of long-term follow-up. The aim of this study was to address the late outcome of DES versus BMS for the treatment of SVG lesions. Methods: A matched, case-control study included 82 patients in each group. Patients groups were matched by gender, age, clinical presentation, and diabetes. The primary study end point was occurrence of major adverse cardiovascular events (MACE). Secondary end points included death, cardiac death, myocardial infarction (MI), and target vessel revascularization (TVR). Results: Clinical and angiographic characteristics were similar between the groups. At 6 months, TVR (hazard ratio [HR] 6.12, 95% confidence interval [CI] 1.39 to 26.93, P = 0.05), and MACE (HR 2.54, 95% CI 1.08 to 5.98, P = 0.04) were higher in the BMS group. At 4 years the risks of MI (P = 0.21), TVR (P = 0.99), and MACE (P = 0.21) were similar between both groups. However, the rates of death (HR 2.74, 95% CI 1.11 to 6.74, P = 0.04) and cardiac death (HR 4.26, 95% CI 1.59 to 11.35, P = 0.01) were significantly higher in the BMS group. Conclusions: These results suggest that the use of DES compared with BMS in the treatment of SVG lesions reduces TVR and MACE at 6 months of follow-up, a benefit that was lost over the next 3-4 years.

    Role of Trimetazidine in Ischemic Preconditioning in Patients With Symptomatic Coronary Artery Disease
    (2015) COSTA, Leandro M. A.; REZENDE, Paulo C.; GARCIA, Rosa M. R.; UCHIDA, Augusto H.; SEGURO, Luis Fernando B. C.; SCUDELER, Thiago L.; BOCCHI, Edimar A.; KRIEGER, Jose E.; HUEB, Whady; RAMIRES, Jose Antonio F.; KALIL FILHO, Roberto
    Ischemic preconditioning (IP) is a powerful cardioprotective cellular mechanism that has been related to the warm-up phenomenon or walk-through angina, and has been documented through the use of sequential exercise tests (ETs). It is known that several drugs, for example, cromokalim, pinacidil, adenosine, and nicorandil, can interfere with the cellular pathways of IP. The purpose of this article is to report the effect of the anti-ischemic agent trimetazidine (TMZ) on IP in symptomatic coronary artery disease (CAD) patients.We conducted a prospective study evaluating IP by the analysis of ischemic parameters in 2 sequential ETs. In phase I, without TMZ, patients underwent ET1 and ET2 with a 30-minute interval between them. In phase II, after 1 week of TMZ 35mg twice daily, all patients underwent 2 consecutive ETs (ET3 and ET4). IP was considered present when the time to 1.0-mm segment ST on electrocardiogram deviation (T-1.0mm) and rate pressure product (RPP) were greater in the second of 2 tests. The improvement in T-1.0mm and RPP were compared in the 2 phases: without TMZ and after 1-week TMZ to assess the action of such drug in myocardial protective mechanisms. ETs were analyzed by 2 independent cardiologists.From 135 CAD patients screened, 96 met inclusion criteria and 62 completed the study protocol. Forty patients manifested IP by demonstrating an improvement in T-1.0mm in ET2 compared with ET1, without the use of any drugs (phase I). In phase II, after 1-week TMZ, 26 patients (65%) did not show any incremental result in ischemic parameters in ET4 compared with ET3. Furthermore, of these patients, 8 (20%) had IP blockage.In this study, TMZ did not add any benefit to IP in patients with stable symptomatic CAD.

    (2014) MELO, Rodrigo Morel Vieira de; HUEB, Whady; REZENDE, Paulo Cury; LIMA, Eduardo Gomes; HUEB, Alexandre Ciappina; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Background: We aim to evaluate in-hospital events and long-term clinical outcomes in patients over 60 years of age with stable coronary artery disease and preserved left ventricular ejection fraction undergoing off-pump or on-pump coronary artery bypass grafting. Methods: The MASS III was a single-center randomized trial that evaluate 308 patients with stable coronary artery disease and preserved ventricular function assigned for: 155 to off-pump and 153 to on-pump CABG. Of this, 176 (58.3%) patients were 60 years or older at the time of randomization (90 of-pump and 86 on-pump). The primary short-term end point was a composite of myocardial infarction, stroke, and overall mortality occurring within 30 days after surgery or before discharge, whichever was later. The primary long-term end point was death from any cause within 5 years, non-fatal myocardial infarction between 30 days and 5 years, or additional revascularization between 30 days and 5 years. Results: On-pump CABG had a higher incidence of 30-day composite outcome than off-pump CABG (15,1% and 5.6%, respectively; P = 0.036). However, after the multivariate analysis, this association lost statistical significance, P = 0.05. After 5-year follow-up, there were no significant differences between both strategies of CABG in the composite end points 16.7% and 15.1%; Hazard Ratio 1.07; CI 0.41 - 1.82; P = 0.71, for off-pump and on-pump CABG respectively. Conclusions: On-pump and off-pump CABG achieved similar results of combined events at short-term and 5-year follow-up.

    (2017) REZENDE, Paulo Cury; HUEB, Whady; RAHMI, Rosa Maria; SCUDELER, Thiago Luis; AZEVEDO, Diogo Freitas Cardoso de; GARZILLO, Cibele Larrosa; SEGRE, Carlos Alexandre Wainrober; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Background: Diabetic patients may be more susceptible to myocardial injury after coronary interventions. Thus, the aim of this study was to assess the release of cardiac biomarkers, CK-MB and troponin, and the findings of new late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) in patients with type 2 diabetes mellitus after elective revascularization procedures for multivessel coronary artery disease (CAD). Methods: Patients with multivessel CAD and preserved systolic ventricular function underwent either elective percutaneous coronary intervention (PCI), off-pump or on-pump bypass surgery (CABG). Troponin and CK-MB were systematically collected at baseline, 6, 12, 24, 36, 48 and 72 h after the procedures. CMR with LGE was performed before and after the interventions. Patients were stratified according to diabetes status at study entry. Biomarkers and CMR results were compared between diabetic and nondiabetics patients. Analyses of correlation were also performed among glycemic and glycated hemoglobin (A1c) levels and troponin and CK-MB peak levels. Patients were also stratified into tertiles of fasting glycemia and A1c levels and were compared in terms of periprocedural myocardial infarction (PMI) on CMR. Results: Ninety (44.5%) of the 202 patients had diabetes mellitus at study entry. After interventions, median peak troponin was 2.18 (0.47, 5.14) and 2.24 (0.69, 5.42) ng/mL (P = 0.81), and median peak CK-MB was 14.1 (6.8, 31.7) and 14.0 (4.2, 29.8) ng/mL (P = 0.43), in diabetic and nondiabetic patients, respectively. The release of troponin and CK-MB over time was statistically similar in both groups and in the three treatments, besides PCI. New LGE on CMR indicated that new myocardial fibrosis was present in 18.9 and 17.3% (P = 0.91), and myocardial edema in 15.5 and 22.9% (P = 0.39) in diabetic and nondiabetic patients, respectively. The incidence of PMI in the glycemia tertiles was 17.9% versus 19.3% versus 18.7% (P = 0.98), and in the A1c tertiles was 19.1% versus 13.3% versus 22.2% (P = 0.88). Conclusions: In this study, diabetes mellitus did not add risk of myocardial injury after revascularization interventions in patients with multivessel coronary artery disease.

    Comparison between off-pump and on-pump coronary artery bypass grafting in patients with severe lesions at the circumflex artery territory: 5-year follow-up of the MASS III trial
    (2015) MELO, Rodrigo Morel Vieira de; HUEB, Whady; REZENDE, Paulo Cury; COSTA, Leandro Menezes Alves da; OIKAWA, Fernando Teiichi Costa; LIMA, Eduardo Gomes; HUEB, Alexandre Ciappina; SCUDELER, Thiago Luis; KALIL FILHO, Roberto
    OBJECTIVES: The technical difficulty in the revascularization of the circumflex artery territory with off-pump surgery may compromise the outcome of this method in clinical follow-up. We aimed to evaluate cardiac events in patients with stable coronary artery disease and severe obstruction of the circumflex system, undergoing coronary artery bypass grafting (CABG) with or without cardiopulmonary bypass. METHODS: MASS III was a single-centre study that evaluated 308 patients with multivessel coronary artery disease randomized to on-pump (153) or off-pump (155) CABG. Of this total, 260 (84.4%) patients had, on coronary angiography, at least one 70% obstruction in the circumflex territory (141 on-pump and 119 off-pump). The combined outcome was death, myocardial infarction, target vessel revascularization (angioplasty or surgery) or hospitalization for cardiac causes. Variables with possible associations (P < 0.1) were included in the multivariate analysis. RESULTS: The two groups were well matched for demographics and clinical and angiographic characteristics. After 5 years of follow-up, off-pump CABG had higher combined events than on-pump had: 25 (21%) vs 17 (12%), hazard ratio 1.88, 95% confidence interval 1.02-.48, P = 0.041. In the multivariate model with the inclusion of the following variables: age (P = 0.09) and complete revascularization (P = 0.68), off-pump surgery remained as a predictor of combined events in 5 years, P = 0.03. CONCLUSIONS: In patients with multivessel coronary artery disease and severe lesions in the circumflex territory, off-pump coronary artery bypass surgery resulted in a higher incidence of cardiac events at 5-year follow-up.
