conferenceObject CARDIOVASCULAR MORTALITY AND MYOCARDIAL INFARCTION AFTER RADIATION THERAPY FOR LEFT VERSUS RIGHT SIDED BREAST CANCER: A META-ANALYSIS(2016) BITTENCOURT, Marcio Sommer; VECSEY-NAGY, Milan; SANTOS, Marilia; SILVA, Carolina; FONSECA, Silvia M.; BITTAR, Cristina S.; HOFF, Paulo G.; KALIL-FILHO, Roberto; HAJJAR, Ludhmila A.- 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.)
conferenceObject Plasma Biomarkers Reflecting High Oxidative Stress Predicts Myocardial Injury Related to Anthracycline Chemotherapy in the CECCY Trial(2018) WANDERLEY JR., Mauro R.; AVILA, Monica S.; FERNANDES-SILVA, Miguel M.; CUNHA-NETO, Edecio; CRUZ, Fatima D.; BRANDAO, Goncalves Sara M.; RIGAUD, Vagner O.; HAJJAR, Ludhmila A.; KALIL FILHO, Roberto; BOCCHI, Edimar A.; AYUB-FERREIRA, Silvia M.conferenceObject Training, Simulation and Validation of Therapeutic Hypothermia as an Adjuvant Treatment in St Segment Elevation Myocardial Infarction(2018) DALLAN, Luis Augusto; RIBEIRO, Marcelo; GIANNETTI, Natali; ROCHITTE, Carlos; NOMURA, Cesar H.; HAJJAR, Ludhmila A.; BERNOCHE, Claudia Y.; LAGE, Silvia G.; NICOLAU, Jose Carlos; OLIVEIRA, Mucio T.; POLASTRI, Thatiane F.; RIBEIRO, Expedito E.; KALIL FILHO, Roberto; LEMOS NETO, Pedro A.; TIMERMAN, Sergio- Platelet Reactivity and Coagulation Markers in Patients with COVID-19(2021) BERTOLIN, Adriadne J.; DALCOQUIO, Talia F.; SALSOSO, Rocio; FURTADO, Remo H. de M.; KALIL-FILHO, Roberto; HAJJAR, Ludhmila A.; SICILIANO, Rinaldo F.; KALLAS, Esper G.; BARACIOLI, Luciano M.; LIMA, Felipe G.; GIRALDEZ, Roberto R.; CAVALHEIRO-FILHO, Cyrillo; VIEIRA, Alexandra; STRUNZ, Celia M. C.; GIUGLIANO, Robert P.; TANTRY, Udaya S.; GURBEL, Paul A.; NICOLAU, Jose C.Introdution COVID-19 is associated with an increased risk of thrombotic events. However, the contribution of platelet reactivity (PR) to the aetiology of the increased thrombotic risk associated with COVID-19 remains unclear. Our aim was to evaluate PR in stable patients diagnosed with COVID-19 and hospitalized with respiratory symptoms (mainly dyspnoea and dry cough), in comparison with a control group comprised of non-hospitalized healthy controls. Methods Observational, case control study that included patients with confirmed COVID-19 (COVID-19 group, n = 60) and healthy individuals matched by age and sex (control group, n = 60). Multiplate electrode aggregometry (MEA) tests were used to assess PR with adenosine diphosphate (MEA-ADP, low PR defined as < 53 AUC), arachidonic acid (MEA-ASPI, low PR < 86 AUC) and thrombin receptor-activating peptide 6 (MEA-TRAP, low PR < 97 AUC) in both groups. Results The rates of low PR with MEA-ADP were 27.5% in the COVID-19 group and 21.7% in the control group (OR = 1.60, p = 0.20); with MEA-ASPI, the rates were, respectively, 37.5% and 22.5% (OR = 3.67, p < 0.001); and with MEA-TRAP, the incidences were 48.5% and 18.8%, respectively (OR = 9.58, p < 0.001). Levels of d-dimer, fibrinogen, and plasminogen activator inhibitor 1 (PAI-1) were higher in the COVID-19 group in comparison with the control group (all p < 0.05). Thromboelastometry was utilized in a subgroup of patients and showed a hypercoagulable state in the COVID-19 group. Conclusion Patients hospitalized with non-severe COVID-19 had lower PR compared to healthy controls, despite having higher levels of d-dimer, fibrinogen, and PAI-1, and hypercoagulability by thromboelastometry.
- High risk coronavirus disease 2019: The primary results of the CoronaHeart multi-center cohort study(2021) GUIMARAES, Patricia O.; SOUZA, Francis R. de; LOPES, Renato D.; BITTAR, Cristina; CARDOZO, Francisco A.; CARAMELLI, Bruno; CALDERARO, Daniela; ALBUQUERQUE, Cicero P.; DRAGER, Luciano F.; FERES, Fausto; BARACIOLI, Luciano; FILHO, Gilson Feitosa; BARBOSA, Roberto R.; RIBEIRO, Henrique B.; RIBEIRO, Expedito; ALVES, Renato J.; SOEIRO, Alexandre; FAILLACE, Bruno; FIGUEIREDO, Estevao; DAMIANI, Lucas P.; VAL, Renata M. do; HUEMER, Natassja; NICOLAI, Lisie G.; HAJJAR, Ludhmila A.; ABIZAID, Alexandre; FILHO, Roberto KalilBackground: Patients with Coronavirus Disease 2019 (COVID-19) may present high risk features during hospitalization, including cardiovascular manifestations. However, less is known about the factors that may further increase the risk of death in these patients. Methods: We included patients with COVID-19 and high risk features according to clinical and/or labo-ratory criteria at 21 sites in Brazil from June 10th to October 23rd of 2020. All variables were collected until hospital discharge or in-hospital death. Results: A total of 2546 participants were included (mean age 65 years; 60.3% male). Overall, 70.8% were admitted to intensive care units and 54.2% had elevated troponin levels. In-hospital mortality was 41.7%. An interaction among sex, age and mortality was found (p = 0.007). Younger women presented higher rates of death than men (30.0% vs 22.9%), while older men presented higher rates of death than women (57.6% vs 49.2%). The strongest factors associated with in-hospital mortality were need for mechanical ventilation (odds ratio [OR] 8.2, 95% confidence interval [CI] 5.4-12.7), elevated C-reactive protein (OR 2.3, 95% CI 1.7-2.9), cancer (OR 1.8, 95 %CI 1.2-2.9), and elevated troponin levels (OR 1.8, 95% CI 1.4-2.3). A risk score was developed for risk assessment of in-hospital mortality. Conclusions: This cohort showed that patients with COVID-19 and high risk features have an elevated rate of in-hospital mortality with differences according to age and sex. These results highlight unique aspects of this population and might help identifying patients who may benefit from more careful initial surveil-lance and potential subsequent interventional therapies.

- Late clinical outcomes of myocardial hybrid revascularization versus coronary artery bypass grafting for complex triple-vessel disease: Long-term follow-up of the randomized MERGING clinical trial(2021) ESTEVES, Vinicius; OLIVEIRA, Marco A. P.; FEITOSA, Fernanda S.; MARIANI JR., Jose; CAMPOS, Carlos M.; HAJJAR, Ludhmila A.; LISBOA, Luiz A.; JATENE, Fabio B.; FILHO, Roberto K.; LEMOS NETO, Pedro A.Objectives This article aimed to compare the outcomes after hybrid revascularization with conventional coronary artery bypass grafting (CABG) surgery. Background The concept of hybrid coronary revascularization combines the advantages of CABG and percutaneous coronary intervention to improve the treatment of patients with complex multivessel disease. Methods The Myocardial hybrid revascularization versus coronary artERy bypass GraftING for complex triple-vessel disease-MERGING study is a pilot randomized trial that allocated 60 patients with complex triple-vessel disease to treatment with hybrid revascularization or conventional CABG (2:1 ratio). The primary outcome was the composite of all-cause death, myocardial infarction, stroke, or unplanned repeat revascularization at 2 years. Results Clinical and anatomical characteristics were similar between groups. After a mean follow-up of 802 +/- 500 days, the primary endpoint rate was 19.3% in the hybrid arm and 5.9% in the CABG arm (p = NS). The incidence of unplanned revascularization increased over time in both groups, reaching 14.5 versus 5.9% in the hybrid and in the CABG groups, respectively (p = .4). Of note, in the hybrid group, there were no reinterventions driven by the occurrence of stent restenosis. Conclusions Hybrid myocardial was feasible but associated with increasing rates of major adverse cardiovascular events during 2 years of clinical follow-up, while the control group treated with conventional surgery presented with low rates of complications during the same period. In conclusion, before more definitive data arise, hybrid revascularization should be applied with careful attention in practice, following a selective case-by-case indication.
- Patients with COVID-19 who experience a myocardial infarction have complex coronary morphology and high in-hospital mortality: Primary results of a nationwide angiographic study(2021) ABIZAID, Alexandre; CAMPOS, Carlos M.; GUIMARAES, Patricia O.; JR, Jose de Ribamar Costa; FALCAO, Breno A. A.; MANGIONE, Fernanda; CAIXETA, Adriano; LEMOS, Pedro A.; BRITO, Fabio S. de; CAVALCANTE, Ricardo; BEZERRA, Cristiano Guedes; CORTES, Leandro; RIBEIRO, Henrique B.; SOUZA, Francis R. de; HUEMER, Natassja; VAL, Renata M. do; CARAMELLI, Bruno; CALDERARO, Daniela; LIMA, Felipe G.; HAJJAR, Ludhmila A.; MEHRAN, Roxana; KALIL FILHO, RobertoObjectives We aimed to explore angiographic patterns and in-hospital outcomes of patients with concomitant coronavirus disease-19 (COVID-19) and myocardial infarction (MI). Background Patients with COVID-19 may experience MI during the course of the viral infection. However, this association is currently poorly understood. Methods This is a multicenter prospective study of consecutive patients with concomitant COVID-19 and MI who underwent coronary angiography. Quantitative and qualitative coronary angiography were analyzed by two observers in an independent core lab. Results A total of 152 patients were included, of whom 142 (93.4%) had COVID-19 diagnosis confirmation. The median time between symptom onset and hospital admission was 5 (1-10) days. A total of 83 (54.6%) patients presented with ST-elevation MI. The median angiographic Syntax score was 16 (9.0-25.3) and 69.0% had multi-vessel disease. At least one complex lesion was found in 73.0% of patients, 51.3% had a thrombus containing lesion, and 57.9% had myocardial blush grades 0/1. The overall in-hospital mortality was 23.7%. ST-segment elevation MI presentation and baseline myocardial blush grades 0 or 1 were independently associated with a higher risk of death (HR 2.75, 95%CI 1.30-5.80 and HR 3.73, 95%CI 1.61-8.61, respectively). Conclusions Patients who have a MI in the context of ongoing COVID-19 mostly present complex coronary morphologies, implying a background of prior atherosclerotic disease superimposed on a thrombotic milieu. The in-hospital prognosis is poor with a markedly high mortality, prompting further investigation to better clarify this newly described condition.
- Physical capacity increase in patients with heart failure is associated with improvement in muscle sympathetic nerve activity(2023) GOES-SANTOS, Beatriz R.; RONDON, Eduardo; FONSECA, Guilherme W. P.; SALES, Allan R. K.; SANTOS, Marcelo R.; ANTUNES-CORREA, Ligia M.; UENO-PARDI, Linda M.; OLIVEIRA, Patricia; TREVIZAN, Patricia F.; FRANCO, Fabio G. Mello; FRAGA, Raffael; ALVES, Maria Janieire N. N.; RONDON, Maria Urbana P. B.; HAJJAR, Ludhmila A.; KALIL FILHO, Roberto; NEGRAO, Carlos E.Background: Exercise training improves physical capacity in patients with heart failure with reduced ejection fraction (HFrEF), but the mechanisms involved in this response is not fully understood. The aim of this study was to determine if physical capacity increase in patients HFrEF is associated with muscle sympathetic nerve activity (MSNA) reduction and muscle blood flow (MBF) increase. Methods: The study included 124 patients from a 17-year database, divided according to exercise training status: 1) exercise-trained (ET, n = 83) and 2) untrained (UNT, n = 41). MSNA and MBF were obtained using microneurography and venous occlusion plethysmography, respectively. Physical capacity was evaluated by cardiopulmonary exercise test. Moderate aerobic exercise was performed 3 times/wk. for 4 months. Results: Exercise training increased peak oxygen consumption (VO2, 16.1 +/- 0.4 vs 18.9 +/- 0.5 mL.kg(-1).min(-1), P < 0.001), LVEF (28 +/- 1 vs 30 +/- 1%, P = 0.027), MBF (1.57 +/- 0.06 vs 2.05 +/- 0.09 mL.min(-1).100 ml(-1), P < 0.001) and muscle vascular conductance (MVC, 1.82 +/- 0.07 vs 2.45 +/- 0.11 units, P < 0.001). Exercise training significantly decreased MSNA (45 +/- 1 vs 32 +/- 1 bursts/min, P < 0.001). The logistic regression analyses showed that MSNA [(OR) 0.921, 95% CI 0.883-0.962, P < 0.001] was independently associated with peak VO2. Conclusions: The increase in physical capacity provoked by aerobic exercise in patients with HFrEF is associated with the improvement in MSNA.
- Liberal Versus Restrictive Transfusion Strategy in Critically Ill Oncologic Patients: The Transfusion Requirements in Critically Ill Oncologic Patients Randomized Controlled Trial(2017) BERGAMIN, Fabricio S.; ALMEIDA, Juliano P.; LANDONI, Giovanni; GALAS, Filomena R. B. G.; FUKUSHIMA, Julia T.; FOMINSKIY, Evgeny; PARK, Clarice H. L.; OSAWA, Eduardo A.; DIZ, Maria P. E.; OLIVEIRA, Gisele Q.; FRANCO, Rafael A.; NAKAMURA, Rosana E.; ALMEIDA, Elisangela M.; ABDALA, Edson; FREIRE, Maristela P.; FILHO, Roberto K.; AULER JR., Jose Otavio C.; HAJJAR, Ludhmila A.Objective: To assess whether a restrictive strategy of RBC transfusion reduces 28-day mortality when compared with a liberal strategy in cancer patients with septic shock. Design: Single center, randomized, double-blind controlled trial. Setting: Teaching hospital. Patients: Adult cancer patients with septic shock in the first 6 hours of ICU admission. Interventions: Patients were randomized to the liberal (hemoglobin threshold, < 9 g/dL) or to the restrictive strategy (hemoglobin threshold, < 7 g/dL) of RBC transfusion during ICU stay. Measurements and Main Results: Patients were randomized to the liberal (n = 149) or to the restrictive transfusion strategy (n = 151) group. Patients in the liberal group received more RBC units than patients in the restrictive group (1 [0-3] vs 0 [0-2] unit; p<0.001). At 28 days after randomization, mortality rate in the liberal group (primary endpoint of the study) was 45% (67 patients) versus 56% (84 patients) in the restrictive group (hazard ratio, 0.74; 95% CI, 0.53-1.04; p = 0.08) with no differences in ICU and hospital length of stay. At 90 days after randomization, mortality rate in the liberal group was lower (59% vs 70%) than in the restrictive group (hazard ratio, 0.72; 95% CI, 0.53-0.97; p = 0.03). Conclusions: We observed a survival trend favoring a liberal transfusion strategy in patients with septic shock when compared with the restrictive strategy. These results went in the opposite direction of the a priori hypothesis and of other trials in the field and need to be confirmed.
