    Objective: With progressive aging, coronary artery disease has been diagnosed at more advanced ages. Although patients aged 65 years or more have been referred to surgical or percutaneous coronary interventions, the best option for coronary artery disease treatment remains uncertain. The current study compared the 3 treatment options for coronary artery disease in patients aged 65 years or more and analyzed the impact of age in treatment options. Methods: Patients were separated according to age: 65 years or more (n = 200) and less than 65 years (n = 411). All patients were followed for 10 years. The rates of overall mortality, acute myocardial infarction, and new revascularizations were analyzed. Results: Of 200 patients aged 65 years or more, 68 were randomized to medical therapy, 68 were randomized to percutaneous coronary intervention, and 64 were randomized to coronary artery bypass grafting. At 10 years, overall survival was 63% (medical therapy), 69% (percutaneous coronary intervention), and 66% (coronary artery bypass grafting) (P = .93). The survival free of combined events was 43% (medical therapy), 38% (percutaneous coronary intervention), and 66% (coronary artery bypass grafting) (P = .007). The survival free of myocardial infarction was 82% (medical therapy), 77% (percutaneous coronary intervention), and 90%(coronary artery bypass grafting) (P = .17), and survival free of new revascularizations was 59% (medical therapy), 58% (percutaneous coronary intervention), and 91% (coronary artery bypass grafting) (P = .0003). When the 2 age groups were compared, survival free of myocardial infarction for patients treated by percutaneous coronary intervention was 77% (older patients) and 92% (younger patients) (P = .004). Conclusions: In this analysis, treatment options for patients aged 65 years or more who have coronary artery disease yield similar overall survival. However, coronary artery bypass grafting was associated with fewer coronary events, and percutaneous coronary intervention was associated with a higher incidence of myocardial infarction.

    Prognostic Value of Coronary and Microvascular Flow Reserve in Patients with Nonischemic Dilated Cardiomyopathy
    (2013) LIMA, Marta F.; MATHIAS JR., Wilson; SBANO, Joao C. N.; CRUZ, Victoria Yezinia de la; ABDUCH, Maria Cristina; LIMA, Marcio S. M.; BOCCHI, Edmar A.; HAJJAR, Ludhmila A.; RAMIRES, Jose A. F.; KALIL FILHO, Roberto; TSUTSUI, Jeane M.
    Background: Coronary and microvascular blood flow reserve have been established as important predictors of prognosis in patients with cardiovascular disease. The aim of this study was to assess the value of coronary flow velocity reserve (CFVR) and real-time myocardial perfusion echocardiography (RTMPE) for predicting events in patients with nonischemic dilated cardiomyopathy. Methods: One hundred ninety-five patients (mean age 54 +/- 12 years; 66% men) with dilated cardiomyopathy (left ventricular ejection fraction < 35% and no obstructive coronary disease on invasive angiography or multi-detector computed tomography) who underwent dipyridamole stress (0.84 mg/kg over 10 min) RTMPE were prospectively studied. CFVR was calculated as the ratio of hyperemic to baseline peak diastolic velocities in the distal left anterior coronary artery. The replenishment velocity (beta), plateau of acoustic intensity (A(N)), and myocardial blood flow reserve were obtained from RTMPE. Results: Mean CFVR was 2.07 +/- 0.52, mean A(N) reserve was 1.05 +/- 0.09, mean beta reserve was 2.05 +/- 0.39, and mean myocardial blood flow reserve (A(N) x beta) was 2.15 +/- 0.48. During a median follow-up period of 29 months, 45 patients had events (43 deaths and two urgent transplantations). Independent predictors of events were left atrial diameter (relative risk, 1.16; 95% confidence interval, 1.08-1.26; P < .001) and beta reserve <= 2.0 (relative risk, 3.22; 95% confidence interval, 1.18-8.79; P < .001). After adjustment for beta reserve, CFVR and myocardial blood flow reserve no longer had predictive value. Left atrial diameter added prognostic value over clinical factors and left ventricular ejection fraction (chi(2) = 36.8-58.5, P < .001). Beta reserve added additional power to the model (chi(2) = 70.2, P < .001). Conclusions: Increased left atrial diameter and depressed beta reserve were independent predictors of cardiac death and transplantation in patients with nonischemic dilated cardiomyopathy. Beta reserve by RTMPE provided incremental predictive value beyond that provided by current known prognostic clinical and echocardiographic factors. (J Am Soc Echocardiogr 2013;26:278-87.)

    O escore de risco de sangramento como preditor de mortalidade em pacientes com síndromes coronarianas agudas
    (2013) NICOLAU, José Carlos; MOREIRA, Humberto Graner; BARACIOLI, Luciano Moreira; SERRANO JR, Carlos Vicente; LIMA, Felipe Galego; FRANKEN, Marcelo; GIRALDEZ, Roberto Rocha; GANEM, Fernando; KALIL FILHO, Roberto; RAMIRES, José Antônio Franchini; MEHRAN, Roxana
    BACKGROUND: It is well known that the occurrence of bleeding increases in-hospital mortality in patients with acute coronary syndromes (ACS), and there is a good correlation between bleeding risk scores and bleeding incidence. However, the role of bleeding risk score as mortality predictor is poorly studied. OBJECTIVE: The main purpose of this paper was to analyze the role of bleeding risk score as in-hospital mortality predictor in a cohort of patients with ACS treated in a single cardiology tertiary center. METHODS: Out of 1655 patients with ACS (547 with ST-elevation ACS and 1118 with non-ST-elevation ACS), we calculated the ACUITY/HORIZONS bleeding score prospectively in 249 patients and retrospectively in the remaining 1416. Mortality information and hemorrhagic complications were also obtained. RESULTS: Among the mean age of 64.3 ± 12.6 years, the mean bleeding score was 18 ± 7.7. The correlation between bleeding and mortality was highly significant (p < 0.001, OR = 5.296), as well as the correlation between bleeding score and in-hospital bleeding (p < 0.001, OR = 1.058), and between bleeding score and in-hospital mortality (adjusted OR = 1.121, p < 0.001, area under the ROC curve 0.753, p < 0.001). The adjusted OR and area under the ROC curve for the population with ST-elevation ACS were, respectively, 1.046 (p = 0.046) and 0.686 ± 0.040 (p < 0.001); for non-ST-elevation ACS the figures were, respectively, 1.150 (p < 0.001) and 0.769 ± 0.036 (p < 0.001). CONCLUSIONS: Bleeding risk score is a very useful and highly reliable predictor of in-hospital mortality in a wide range of patients with acute coronary syndromes, especially in those with unstable angina or non-ST-elevation acute myocardial infarction.

    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.

    ON-PUMP VERSUS OFF-PUMP CORONARY ARTERY BYPASS SURGERY IN PATIENTS WITH ADVANCED AGE: FIVE-YEAR FOLLOW-UP OF MASS III TRIAL
    (2013) MELO, Rodrigo M. V.; HUEB, Whady; OIKAWA, Fernando T. C.; COSTA, Leandro; SERRANO, Carlos; GARZILLO, Cibele; REZENDE, Paulo; LIMA, Eduardo; FAVARATO, Desiderio; HUEB, Alexandre; RAMIRES, Jose; KALIL-FILHO, Roberto
    Background: Advanced age is associated with increased mortality and morbidity in patients undergoing coronary artery bypass grafting (CABG), which may be a consequence of cardiopulmonary bypass. We aim to evaluate cardiac events and long-term clinical outcome in patients with advanced age and stable coronary artery disease (CAD) undergoing off-pump (OPCAB) and on-pump (ONCAB) CABG. Methods: The MASS III was a single-center randomized trial that evaluate 308 patients with stable CAD and preserved ventricular function assigned for: 155 to off-pump and 153 to on-pump CABG. Of this, 176 (58.3%) patients had 60 years or older at the time of randomization (90 of-pump and 86 on-pump). Primary composite end points were death, myocardial infarction, further revascularization, or stroke. Results: The two randomized groups were well-matched for baseline demographic, clinical, and angiographic characteristics. The mean age was 67.2 (±5.0) years. In hospital analysis ONCAB patients had a higher incidence of postoperative stroke or myocardial infarction: 13 (15.1%) vs 5 (5.6%); p=0.036. After 5-year follow-up, there were no significant differences between both strategies of CABG in the composite end points 29.1% vs 27.8%; (Hazard Ratio 1.07; CI 0.62 – 1.87; p=0.8) for ONCAB and OPCAB respectively. Conclusion: In this advanced age population, off-pump surgery did not add benefit in clinical outcome at 5-year follow-up.

    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.
