    (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.

    Type 2 diabetes mellitus and myocardial ischemic preconditioning in symptomatic coronary artery disease patients
    (2015) REZENDE, Paulo Cury; RAHMI, Rosa Maria; UCHIDA, Augusto Hiroshi; COSTA, Leandro Menezes Alves da; SCUDELER, Thiago Luis; GARZILLO, Cibele Larrosa; LIMA, Eduardo Gomes; SEGRE, Carlos Alexandre Wainrober; GIRARDI, Priscyla; TAKIUTI, Myrthes; SILVA, Marcela Francisca; HUEB, Whady; RAMIRES, Jose Antonio Franchini; FILHO, Roberto Kalil
    Background: The influence of diabetes mellitus on myocardial ischemic preconditioning is not clearly defined. Experimental studies are conflicting and human studies are scarce and inconclusive. Objectives: Identify whether diabetes mellitus intervenes on ischemic preconditioning in symptomatic coronary artery disease patients. Methods: Symptomatic multivessel coronary artery disease patients with preserved systolic ventricular function and a positive exercise test underwent two sequential exercise tests to demonstrate ischemic preconditioning. Ischemic parameters were compared among patients with and without type 2 diabetes mellitus. Ischemic preconditioning was considered present when the time to 1.0 mm ST deviation and rate pressure-product were greater in the second of 2 exercise tests. Sequential exercise tests were analyzed by 2 independent cardiologists. Results: Of the 2,140 consecutive coronary artery disease patients screened, 361 met inclusion criteria, and 174 patients (64.2 +/- 7.6 years) completed the study protocol. Of these, 86 had the diagnosis of type 2 diabetes. Among diabetic patients, 62 (72%) manifested an improvement in ischemic parameters consistent with ischemic preconditioning, whereas among nondiabetic patients, 60 (68%) manifested ischemic preconditioning (p = 0.62). The analysis of patients who demonstrated ischemic preconditioning showed similar improvement in the time to 1.0 mm ST deviation between diabetic and nondiabetic groups (79.4 +/- 47.6 vs 65.5 +/- 36.4 s, respectively, p = 0.12). Regarding rate pressure-product, the improvement was greater in diabetic compared to nondiabetic patients (3011 +/- 2430 vs 2081 +/- 2139 bpm x mmHg, respectively, p = 0.01). Conclusions: In this study, diabetes mellitus was not associated with impairment in ischemic preconditioning in symptomatic coronary artery disease patients. Furthermore, diabetic patients experienced an improvement in this significant mechanism of myocardial protection.

    Long-Term Follow-Up of Implantable Cardioverter-Defibrillator for Secondary Prevention in Chagas' Heart Disease
    (2012) MARTINELLI, Martino; SIQUEIRA, Sergio Freitas de; STERNICK, Eduardo Back; RASSI JR., Anis; COSTA, Roberto; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Assessing the efficacy of implantable cardioverter-defibrillators (ICD) in patients with Chagas' heart disease (ChHD) and identifying the clinical predictors of mortality and ICD shock during long-term follow-up. ChHD is associated with ventricular tachyarrhythmias and an increased risk of sudden cardiac death. Although ChHD is a common form of cardiomyopathy in Latin American ICD users, little is known about its efficacy in the treatment of this population. The study cohort included 116 consecutive patients with ChHD and an ICD implanted for secondary prevention. Of the 116 patients, 83 (72%) were men; the mean age was 54 +/- 10.7 years. Several clinical variables were tested in a multivariate Cox model for predicting long-term mortality. The average follow-up was 45 +/- 32 months. New York Heart Association class I-II developed in 83% of patients. The mean left ventricular ejection fraction was 42 +/- 16% at implantation. Of the 116 patients, 58 (50%) had appropriate shocks and 13 (11%) had inappropriate therapy. A total of 31 patients died (7.1% annual mortality rate). New York Heart Association class III (hazard ratio [HR] 3.09, 95% confidence interval 1.37 to 6.96, p = 0.0064) was a predictor of a worse prognosis. The left ventricular ejection fraction (HR 0.972, 95% confidence interval 0.94 to 0.99, p = 0.0442) and low cumulative right ventricular pacing (HR 0.23, 95% confidence interval 0.11 to 0.49, p = 0.0001) were predictors of better survival. The left ventricular diastolic diameter was an independent predictor of appropriate shock (I-ER 1.032, 95% confidence interval 1.004 to 1.060, p = 0.025). In conclusion, in a long-term follow-up, ICD efficacy for secondary sudden cardiac death prevention in patients with ChHD was marked by a favorable annual rate of all-cause mortality (7.1%); 50% of the cohort received appropriate shock therapy. New York Heart Association class III and left ventricular ejection fraction were independent predictors of worse prognosis, and low cumulative right ventricular pacing defined better survival.

    Effects of Cardiac Resynchronization Therapy on Muscle Sympathetic Nerve Activity
    (2014) KUNIYOSHI, Ricardo R.; MARTINELLI, Martino; NEGRAO, Carlos E.; SIQUEIRA, Sergio F.; RONDON, Maria U. P. B.; TROMBETTA, Ivani C.; KUNIYOSHI, Fatima H. S.; LATERZA, Mateus C.; NISHIOKA, Silvana A. D'Orio; COSTA, Roberto; TAMAKI, Wagner T.; CREVELARI, Elizabeth S.; PEIXOTO, Giselle De Lima; RAMIRES, Jose A. F.; KALIL, Roberto
    IntroductionMuscle sympathetic nerve activity (MSNA) is an independent prognostic marker in patients with heart failure (HF). Therefore, its relevance to the treatment of HF patients is unquestionable. ObjectivesIn this study, we investigated the effects of cardiac resynchronization therapy (CRT) on MSNA response at rest and during exercise in patients with advanced HF. MethodsWe assessed 11 HF patients (51 3.4 years; New York Heart Association class III-IV; left ventricular ejection fraction 27.8 2.2%; optimal medical therapy) submitted to CRT. Evaluations were made prior to and 3 months after CRT. MSNA was performed at rest and during moderate static exercise (handgrip). Peak oxygen consumption (VO2) was evaluated by means of cardiopulmonary exercise test. HF patients with advanced NYHA class without CRT and healthy individuals were also studied. ResultsCRT reduced MSNA at rest (48.9 +/- 11.1 bursts/min vs 33.7 +/- 15.3 bursts/min, P < 0.05) and during handgrip exercise (MSNA 62.3 +/- 13.1 bursts/min vs 46.9 +/- 14.3 bursts/min, P < 0.05). Among HF patients submitted to CRT, the peak VO2 increased (12.9 +/- 2.8 mL/kg/min vs 16.5 +/- 3.9 mL/kg/min, P < 0.05) and an inverse correlation between peak VO2 and resting MSNA (r = -0.74, P = 0.01) was observed. ConclusionsIn patients with advanced HF and severe systolic dysfunction: (1) a significant reduction of MSNA (at rest and during handgrip) occurred after CRT, and this behavior was significantly superior to HF patients receiving only medical therapy; (2) MSNA reduction after CRT had an inverse correlation with O-2 consumption outcomes.

    Coronary atherosclerotic burden assessed by SYNTAX scores and outcomes in surgical, percutaneous or medical strategies: a retrospective cohort study
    (2022) SCUDELER, Thiago Luis; FARKOUH, Michael E.; HUEB, Whady; REZENDE, Paulo C.; CAMPOLINA, Alessandro G.; MARTINS, Eduardo Bello; GODOY, Lucas C.; SOARES, Paulo Rogerio; RAMIRES, Jose A. F.; FILHO, Roberto Kalil
    Introduction Coronary atherosclerotic burden and SYNTAX Score (SS) are predictors of cardiovascular events. Objectives To investigate the value of SYNTAX scores (SS, SYNTAX Score II (SSII) and residual SYNTAX Score (rSS)) for predicting cardiovascular events in patients with coronary artery disease (CAD). Design Retrospective cohort study. Setting Single tertiary centre. Participants Medicine, Angioplasty or Surgery Study database patients with stable multivessel CAD and preserved ejection fraction. Interventions Patients with CAD undergoing coronary artery bypass graft (CABG), percutaneous coronary intervention (PCI) or medical treatment (MT) alone from January 2002 to December 2015. Primary and secondary outcomes Primary: 5-year allcause mortality. Secondary: composite of all-cause death, myocardial infarction, stroke and subsequent coronary revascularisation at 5 years. Results A total of 1719 patients underwent PCI (n=573), CABG (n=572) or MT (n=574) alone. The SS was not considered an independent predictor of 5-year mortality in the PCI (low, intermediate and high SS at 6.5%, 6.8% and 4.3%, respectively, p=0.745), CABG (low, intermediate and high SS at 5.7%, 8.0% and 12.1%, respectively, p=0.194) and MT (low, intermediate and high SS at 6.8%, 6.9% and 6.5%, respectively, p=0.993) cohorts. The SSII (low, intermediate and high SSII at 3.6% vs 7.9% vs 10.5%, respectively, p<0.001) was associated with a higher mortality risk in the overall population. Within each treatment strategy, SSII was associated with a significant 5-year mortality rate, especially in CABG patients with higher SSII (low, intermediate and high SSII at 1.8%, 9.7% and 10.0%, respectively, p=0.004) and in MT patients with high SSII (low, intermediate and high SSII at 5.0%, 4.7% and 10.8%, respectively, p=0.031). SSII demonstrated a better predictive accuracy for mortality compared with SS and rSS (c-index=0.62). Conclusions Coronary atherosclerotic burden alone was not associated with significantly increased risk of all-cause mortality. The SSII better discriminates the risk of death.

    Impact of diabetes mellitus on ischemic cardiomyopathy. Five-year follow-up. REVISION-DM trial
    (2018) HUEB, Thiago; ROCHA, Mauricio S.; SIQUEIRA, Sergio F.; NISHIOKA, Silvana Angelina D'Orio; PEIXOTO, Giselle L.; SACCAB, Marcos M.; LIMA, Eduardo Gomes; GARCIA, Rosa Maria Rahmi; RAMIRES, Jos Antonio F.; KALIL FILHO, Roberto; MARTINELLI FILHO, Martino
    Background: Patients with ischemic cardiomyopathy and severe left ventricular dysfunction have a worse survival prognosis than patients with preserved ventricular function. The role of diabetes in the long-term prognosis of this patient group is unknown. This study investigated whether the presence of diabetes has a long-term impact on left ventricular function. Methods: Patients with coronary artery disease who underwent coronary artery bypass graft surgery, percutaneous coronary intervention, or medical therapy alone were included. All patients had multivessel disease and left ventricular ejection fraction measurements. Overall mortality, nonfatal myocardial infarction, stroke, and additional interventions were investigated. Results: From January 2009 to January 2010, 918 consecutive patients were selected and followed until May 2015. They were separated into 4 groups: G1, 266 patients with diabetes and ventricular dysfunction; G2, 213 patients with diabetes without ventricular dysfunction; G3, 213 patients without diabetes and ventricular dysfunction; and G4, 226 patients without diabetes but with ventricular dysfunction. Groups 1, 2, 3, and 4, respectively, had a mortality rate of 21.6, 6.1, 4.2, and 10.6% (P < .001); nonfatal myocardial infarction of 5.3, .5, 7.0, and 2.6% (P < .001); stroke of .40, .45, .90, and .90% (P = NS); and additional intervention of 3.8, 11.7, 10.3, and 2.6% (P < .001). Conclusion: In this sample, regardless of the treatment previously received patients with or without diabetes and preserved ventricular function experienced similar outcomes. However, patients with ventricular dysfunction had a worse prognosis compared with those with normal ventricular function; patients with diabetes had greater mortality than patients without diabetes.

    In-hospital death in acute coronary syndrome was related to admission glucose in men but not in women
    (2012) TAKADA, Julio Yoshio; RAMOS, Rogerio Bicudo; ROZA, Larissa Cardoso; AVAKIAN, Solange Desiree; RAMIRES, Jose Antonio Franchini; MANSUR, Antonio de Padua
    Background: Admission hyperglycaemia is associated with mortality in patients with acute coronary syndrome (ACS), but controversy exists whether hyperglycaemia uniformly affects both genders. We evaluated coronary risk factors, gender, hyperglycaemia and their effect on hospital mortality. Methods: 959 ACS patients (363 women and 596 men) were grouped based on glycaemia >= or < 200 mg/dL and gender: men with glucose < 200 mg/dL (menG-); women with glucose < 200 mg/dL (womenG-); men with glucose >= 200 mg/dL (menG+); and women with glucose >= 200 mg/dL (womenG+). A logistic regression analysis compared the relation between gender and glycaemia groups and death, adjusted for coronary risk factors and laboratory data. Results group: menG- had lower mortality than menG+ (OR = 0.172, IC95% 0.062-0.478), and womenG+ (OR = 0.275, IC95% 0.090-0.841); womenG- mortality was lower than menG+ (OR = 0.230, IC95% 0.074-0.717). No difference was found between menG+ vs womenG+ (p = 0.461), or womenG- vs womenG+ (p = 0.110). Age (OR = 1.067, IC95% 1.031-1.104), EF (OR = 0.942, IC95% 0.915-0.968), and serum creatinine (OR = 1.329, IC95% 1.128-1.566) were other independent factors related to in-hospital death. Conclusions: Death was greater in hyperglycemic men compared to lower blood glucose men and women groups, but there was no differences between women groups in respect to glycaemia after adjustment for coronary risk factors.

    Effect of chronic kidney disease in ischemic cardiomyopathy Long-term follow-up-REVISION-DM2 trial
    (2019) HUEB, Thiago Ovanessian; LIMA, Eduardo Gomes; ROCHA, Mauricio S.; SIQUEIRA, Sergio F.; NISHIOKA, Silvana Angelina Dorio; PEIXOTO, Giselle L.; SACCAB, Marcos M.; GARCIA, Rosa Maria Rahmi; RAMIRES, Jose Antonio F.; KALIL FILHO, Roberto; MARTINELLI FILHO, Martino
    A strong association exists between chronic kidney disease (CKD) and coronary artery disease (CAD). The role of CKD in the long-term prognosis of CAD patients with versus those without CKD is unknown. This study investigated whether CKD affects ventricular function. From January 2009 to January 2010, 918 consecutive patients were selected from an outpatient database. Patients had undergone percutaneous, surgical, or clinical treatment and were followed until May 2015. In patients with preserved renal function (n = 405), 73 events (18%) occurred, but 108 events (21.1%) occurred among those with CKD (n = 513) (P < .001). Regarding left ventricular ejection fraction (LVEF) <50%, we found 84 events (21.5%) in CKD patients and 12 (11.8%) in those with preserved renal function (P < .001). The presence of LVEF <50% brought about a modification effect. Death occurred in 22 (5.4%) patients with preserved renal function and in 73 (14.2%) with CKD (P < .001). In subjects with LVEF <50%, 66 deaths (16.9%) occurred in CKD patients and 7 (6.9%) in those with preserved renal function (P = .001). No differences were found in CKD strata regarding events or overall death among those with preserved LVEF. In a multivariate model, creatinine clearance remained an independent predictor of death (P < .001). We found no deleterious effects of CKD in patients with CAD when ventricular function was preserved. However, there was a worse prognosis in patients with CKD and ventricular dysfunction. Resgistry number is ISRCTN17786790 at .

    Unexplained sudden death in patients on the waiting list for renal transplantation
    (2011) LIMA, Jose Jayme Galvao De; GOWDAK, Luis Henrique Wolff; PAULA, Flavio Jota de; ARANTES, Rodolfo Leite; CESAR, Luiz Antonio Machado; RAMIRES, Jose Antonio Franchini; KRIEGER, Eduardo M.
    Background. The incidence of unexplained sudden death (SD) and the factors involved in its occurrence in patients with chronic kidney disease are not well known. Methods. We investigated the incidence and the role of co-morbidities in unexplained SD in 1139 haemodialysis patients on the renal transplant waiting list. Results. Forty-four patients died from SD of undetermined causes (20% of all deaths; 3.9 deaths/1000 patients per year), while 178 died from other causes and 917 survived. SD patients were older and likely to have diabetes, hypertension, past/present cardiovascular disease, higher left ventricular mass index, and lower ejection fraction. Multivariate analysis showed that cardiovascular disease of any type was the only independent predictor of SD (P = 0.0001, HR = 2.13, 95% CI 1.46-3.22). Alterations closely associated with ischaemic heart disease like angina, previous myocardial infarction and altered myocardial scan were not independent predictors of SD. The incidence of unexplained SD in these haemodialysis patients is high and probably a consequence of pre-existing cardiovascular disease. Conclusions. Factors influencing SD in dialysis patients are not substantially different from factors in the general population. The role played by ischaemic heart disease in this context needs further evaluation.
