ABSTRACT

ABSTRACT Introduction: Heart rate control by the autonomic nervous system (ANS) is impaired in heart transplant (HT) recipients, leading to increased resting heart rate, metabolic demand, and fatigue, which can impair their quality of life (QoL). In this study, we hypothesized the association of hemodynamics and autonomic function as predictors of QoL in HT recipients. Methods: This is a cross-sectional study conducted with HT recipients aged ≥ 18 years at ambulatorial accompaniment. Blood pressure was used for hemodynamics assessment, and heart rate variability (HRV) was used for ANS assessment. QoL was assessed by the 36-item Short Form Health Survey. The significance level was set as P≤0.05. Results: Twenty-two volunteers were included in the study. Systolic blood pressure (SBP) and double product (DP) were significantly negatively associated with the physical functioning domain of QoL. DP, the number of consecutive normal RR interval differences > 50 ms (NN50), and the percentage of normal RR intervals that differed by > 50 ms from the adjacent interval (PNN50) exhibited negative association with the physical role domain. NN50 and PNN50 were significantly associated with bodily pain, social functioning, and emotional role domains. SBP was negatively associated with the vitality domain. Considering general and mental health domains, no variable demonstrated significant association. DP, NN50, and PNN50 were negatively associated with the total score of QoL. Conclusion: This study demonstrated DP and HRV as predictors of QoL in HT recipients. These innovative results can become a relevant therapeutic target for improving QoL in HT recipients prior to its deterioration.

ABSTRACT

Abstract Background In Brazil the factors involved in the risk of death in patients with COVID-19 have not been well established. Objective To analyze whether elevations of high-sensitivity troponin I (hTnI) levels influence the mortality of patients with COVID-19. Methods Clinical and laboratory characteristics of hospitalized patients with COVID-19 were collected upon hospital admission. Univariate and binary logistic regression analyzes were performed to assess the factors that influence mortality. P-value<0.05 was considered significant. Results This study analyzed192 patients who received hospital admission between March 16 and June 2, 2020 and who were discharged or died by July 2, 2020. The mean age was 70±15 years, 80 (41.7%) of whom were women. In comparison to those who were discharged, the 54 (28.1%) who died were older (79±12 vs 66±15years; P=0.004), and with a higher Charlson´s index (5±2 vs 3±2; P=0.027). More patients, aged≥60years (P <0.0001), Charlson´s index>1 (P=0.004), lung injury>50% in chest computed tomography (P=0.011), with previous coronary artery disease (P=0.037), hypertension (P=0.033), stroke (P=0.008), heart failure (P=0.002), lymphocytopenia (P=0.024), high D-dimer (P=0.024), high INR (P=0.003), hTnI (P<0.0001), high creatinine (P<0.0001), invasive mechanical ventilation (P<0.0001), renal replacement therapy (P<0.0001), vasoactive amine (P<0.0001), and transfer to the ICU (P=0.001), died when compared to those who were discharged. In logistic regression analysis, elevated hTnI levels (OR=9.504; 95% CI=1.281-70.528; P=0.028) upon admission, and the need for mechanical ventilation during hospitalization (OR=46.691; 95% CI=2.360-923.706; P=0.012) increased the chance of in-hospital mortality. Conclusion This study suggests that in COVID-19 disease, myocardial injury upon hospital admission is a harbinger of poor prognosis.

ABSTRACT

Resumo Fundamento: A proteína C-reativa (PCR) é um biomarcador de inflamação preditor de eventos adversos em procedimentos cardiovasculares. Na avaliação do implante da válvula aórtica transcateter (transcatheter aortic valve implantation, TAVI) em relação ao prognóstico de longo prazo ainda é incipiente. Objetivo: Avaliar a PCR como marcador prognóstico no primeiro ano pós-TAVI na estenose aórtica (EAo). Métodos: A PCR foi avaliada na primeira semana do peroperatório numa coorte de casos retrospectiva com EAo. Correlacionou-se a PCR pré- e pós-TAVI com a mortalidade e foram pesquisados fatores preditores de mortalidade em 1 ano. Realizada regressão de Cox multivariada para identificar os preditores independentes de óbito em 1 ano. Resultados: Estudados 130 pacientes submetidos a TAVI, com mediana de idade de 83 anos, sendo 49% deles do sexo feminino. A PCR pré-TAVI elevada (> 0,5 mg/dL) ocorreu em 34,5% dos casos. O pico de PCR foi 7,0 (5,3-12,1) mg/dL no quarto dia. A mortalidade em 1 ano foi 14,5% (n = 19), sendo maior nos grupos com PCR pré-TAVI elevada (68,8% vs 29,1%; p = 0,004) e pico de PCR ≥ 10,0 mg/dL (64,7% vs 30,8%; p = 0,009). Os fatores preditores independentes de mortalidade foram insuficiência renal aguda (IRA) [razão de risco (RR) = 7,43; intervalo de confiança de 95% (IC95%), 2,1-24,7; p = 0,001], PCR pré-TAVI elevada [RR = 4,15; IC95%, 1,3-12,9; p=0,01] e hemotransfusão volumosa [HR = 4,68; 1,3-16,7; p = 0,02]. Conclusões: A PCR pré-TAVI elevada mostrou-se fator preditor independente de mortalidade no primeiro ano, assim como a ocorrência de IRA e hemotransfusões volumosas.


Abstract Background: C-reactive protein (CRP) is an inflammation biomarker that can be a predictor of adverse events in cardiovascular procedures. Its use in the assessment of long-term prognosis of transcatheter aortic valve implantation (TAVI) is still incipient. Objective: To evaluate CRP as a prognostic marker in the first year after TAVI in aortic stenosis (AoS). Methods: CRP was assessed on the first postoperative week in a retrospective cohort of patients with AoS. Pre- and post- CRP levels were correlated with mortality, and predictors of 1-year mortality were investigated. Multivariate Cox regression was performed to identify independent factors of 1-year mortality. Results: This study evaluated 130 patients who underwent TAVI, with median age of 83 years, and 49% of women. High pre-TAVI CRP (> 0.5 mg/dL) was observed in 34.5% of the cases. Peak CRP was 7.0 (5.3-12.1) mg/dL no quarto dia. The rate of 1-year mortality was 14.5% (n = 19), being greater in the groups with high pre-TAVI CRP (68.8% vs 29.1%; p = 0,004) and with peak CRP ≥ 10.0 mg/dL (64.7% vs 30.8%; p = 0,009). Independent predictors of mortality were acute renal failure (ARF) (hazard ratio [HR] = 7.43; 95% confidence interval [95%CI], 2.1-24.7; p = 0,001), high pre-TAVI CRP (HR 4.15; 95%CI, 1.3-12.9; p = 0.01), and large blood transfusion [HR 4,68; 1,3-16,7; p = 0.02]. Conclusions: High pre-TAVI CRP showed to be an independent predictor of 1-year mortality, as well as the presence of ARF and large blood transfusions.

ABSTRACT

Transcatheter aortic valve implantation (TAVI) has become a therapeutic option for high-risk or non-operable patients with severe symptomatic aortic stenosis. Atrioventricular conduction disturbances requiring permanent pacemaker (PPM) are a common and clinically important complication. Objectives: To evaluate the incidence of conduction disorders (CDs) after TAVI and the need for subsequent PPM implantation. To identify the predictors of postoperative PPM implantation. Methods: Retrospective study. All patients who underwent TAVI in a public hospital from December/2011 to June/2016 were included. Multivariate analysis was conducted to establish the predictor of permanent pacemaker implantation. Survival curves were constructed by the Kaplan-Meyer method. Statistically significant variables were those with p value < 0.05. Results: 64 patients with AS underwent TAVI. Eleven patients were excluded. TAVI induced a new CD in 40 (77%) of the remaining 53 patients. The most common new CDs were 3rd degree AV block (32%) and left bundle branch block (30%). Sixteen patients (30,2%) underwent PPM implantation during the index hospitalization. On univariate analysis the risk factors for PPM implantation were CoreValve® use (OR: 1,76; P = 0,005), larger prosthesis implantation (P = 0,015), presence of a QRS ≥ 120 ms (OR: 5,62; P = 0,012), and 1st degree AV block (OR: 13; P = 0.008). On multivariate analysis the presence of 1st degree AV block predicted the need for PPM. Conclusion: TAVI induced CDs requiring PPM in 30% of the patients. The presence of 1st degree AV block predicted the need for PPM

ABSTRACT

Abstract Objective: To evaluate the efficacy of triclosan-coated suture for the reduction of infection in saphenectomy wounds of patients undergoing coronary artery bypass graft (CABG) surgery. Methods: A total of 508 patients who underwent saphenectomy in CABG surgery were included in a prospective, randomized, double-blind trial from February/2011 to June/2014. Patients were randomized into the triclosan-coated suture group (n= 251) and the conventional non-antibiotic suture group (n=257). Demographic (gender and age), clinical (body mass index, diabetes, and use of analgesics), and intraoperative (cardiopulmonary bypass and cross-clamp times) variables and those related to the saphenectomy wound (pain, dehiscence, erythema, infection, necrosis, and hyperthermia) were measured and analyzed. Results: Of the 508 patients who underwent saphenectomy, 69.9% were males and 40.2% were diabetic. Thirty-three (6.5%) patients presented infection: 13 (5.3%) with triclosan and 20 (7.9%) with conventional suture (P=0.281). Among diabetic patients (n=204), triclosan suture was used in 45.1% with four cases of infection; conventional suture was used in 54.9% of them, with 11 cases of infection. Most patients (94.3%) underwent on-pump CABG. Wound pain was observed in 9.9% of patients with triclosan-coated suture and in 17.9% with conventional suture (P=0.011). Wound hyperthermia was found in 1.6% of patients with triclosan-coated suture and in 5.4% of those with conventional suture (P=0.028). Conclusion: Triclosan-coated suture shows lower infection rate in saphenectomy of patients undergoing CABG, although the differences were not statistically significant. Pain and wound hyperthermia were less frequent in patients with triclosan-coated sutures compared with conventional sutures.

ABSTRACT

Abstract Objective: Transcatheter aortic valve replacement has been an alternative to invasive treatment for symptomatic severe aortic stenosis in high risk patients. The primary endpoint was 30-day and 1-year mortality from any cause. Secondary endpoints were to compare the clinical and echocardiographic variation pre-and post- transcatheter aortic valve replacement, and the occurrence of complications throughout a 4-year follow-up period. Methods: This prospective cohort, nestled to a multicenter study (Registro Brasileiro de Implante de Bioprótese por Cateter), describes the experience of a public tertiary center in transcatheter aortic valve replacement. All patients who underwent this procedure between October 2011 and February 2016 were included. Results: Fifty-eight patients underwent transcatheter aortic valve replacement. The 30-day all-cause mortality was 5.2% (n=3) and after 1 year was 17.2% (n=10). A significant improvement in New York Heart Association functional classification was observed when comparing pre-and post- transcatheter aortic valve replacement (III or IV 84.4% versus 5.8%; P<0.001). A decline in peak was observed (P<0.001) and mean (P<0.001) systolic transaortic gradient. The results of peak and mean post-implant transaortic gradient were sustained after one year (P=0.29 and P=0.36, respectively). Left ventricular ejection fraction did not change significantly during follow-up (P=0.41). The most frequent complications were bleeding (28.9%), the need for permanent pacemaker (27.6%) and acute renal injury (20.6%). Conclusion: Mortality and complications in this study were consistent with worldwide experience. Transcatheter aortic valve replacement had positive clinical and hemodynamic results, when comparing pre-and post-procedure, and the hemodynamic profile of the prosthesis was sustained throughout follow-up.

ABSTRACT

Abstract Objective: To assess heart rhythm and predictive factors associated with sinus rhythm after one year in patients with rheumatic valve disease undergoing concomitant surgical treatment of atrial fibrillation. Operative mortality, survival and occurrence of stroke after one year were also evaluated. Methods: Retrospective longitudinal observational study of 103 patients undergoing rheumatic mitral valve surgery and ablation of atrial fibrillation using uni- or bipolar radiofrequency between January 2013 and December 2014. Age, gender, functional class (NYHA), type of atrial fibrillation, EuroSCORE, duration of atrial fibrillation, stroke, left atrial size, left ventricular ejection fraction, cardiopulmonary bypass time, myocardial ischemia time and type of radiofrequency were investigated. Results: After one year, 66.3% of patients were in sinus rhythm. Sinus rhythm at hospital discharge, lower left atrial size in the preoperative period and bipolar radiofrequency were associated with a greater chance of sinus rhythm after one year. Operative mortality was 7.7%. Survival rate after one year was 92.3% and occurrence of stroke was 1%. Conclusion: Atrial fibrillation ablation surgery with surgical approach of rheumatic mitral valve resulted in 63.1% patients in sinus rhythm after one year. Discharge from hospital in sinus rhythm was a predictor of maintenance of this rhythm. Increased left atrium and use of unipolar radiofrequency were associated with lower chance of sinus rhythm. Operative mortality rate of 7.7% and survival and stroke-free survival contribute to excellent care results for this approach.

ABSTRACT

Abstract Background: Transcatheter aortic valve implantation has become an option for high-surgical-risk patients with aortic valve disease. Objective: To evaluate the in-hospital and one-year follow-up outcomes of transcatheter aortic valve implantation. Methods: Prospective cohort study of transcatheter aortic valve implantation cases from July 2009 to February 2015. Analysis of clinical and procedural variables, correlating them with in-hospital and one-year mortality. Results: A total of 136 patients with a mean age of 83 years (80-87) underwent heart valve implantation; of these, 49% were women, 131 (96.3%) had aortic stenosis, one (0.7%) had aortic regurgitation and four (2.9%) had prosthetic valve dysfunction. NYHA functional class was III or IV in 129 cases (94.8%). The baseline orifice area was 0.67 ± 0.17 cm2 and the mean left ventricular-aortic pressure gradient was 47.3±18.2 mmHg, with an STS score of 9.3% (4.8%-22.3%). The prostheses implanted were self-expanding in 97% of cases. Perioperative mortality was 1.5%; 30-day mortality, 5.9%; in-hospital mortality, 8.1%; and one-year mortality, 15.5%. Blood transfusion (relative risk of 54; p = 0.0003) and pulmonary arterial hypertension (relative risk of 5.3; p = 0.036) were predictive of in-hospital mortality. Peak C-reactive protein (relative risk of 1.8; p = 0.013) and blood transfusion (relative risk of 8.3; p = 0.0009) were predictive of 1-year mortality. At 30 days, 97% of patients were in NYHA functional class I/II; at one year, this figure reached 96%. Conclusion: Transcatheter aortic valve implantation was performed with a high success rate and low mortality. Blood transfusion was associated with higher in-hospital and one-year mortality. Peak C-reactive protein was associated with one-year mortality.


Resumo Fundamento: O implante de válvula aórtica por cateter tornou-se uma opção para pacientes com doença valvar aórtica de elevado risco cirúrgico. Objetivo: Avaliar os resultados dos seguimentos intra-hospitalar e de até 1 ano do implante de válvula aórtica por cateter. Métodos: Estudo de coorte prospectiva de casos de implante de válvula aórtica por cateter entre julho de 2009 e fevereiro de 2015. Análise de variáveis clínicas e do procedimento, correlacionando com mortalidade intra-hospitalar e de 1 ano. Resultados: Foram submetidos ao implante 136 pacientes, com média de idade de 83 (80-87) anos, sendo 49% mulheres, 131 (96,3%) deles com estenose aórtica, um (0,7%) com insuficiência aórtica e quatro (2,9%) com disfunção de prótese. A classe funcional da NYHA foi III ou IV em 129 (94,8%) casos. A área valvar inicial foi 0,67 ± 0,17 cm2 e o gradiente ventrículo esquerdo-aorta médio de 47,3 ± 18,2 mmHg, com STS de 9,3% (4,8%-22,3%). As próteses implantadas eram autoexpansíveis em 97% dos casos. A mortalidade peroperatória em 1,5% dos casos; em 30 dias em 5,9%; intra-hospitalar em 8,1%; e após 1 ano em 15,5% dos casos. A hemotransfusão (risco relativo de 54; p = 0,0003) e a hipertensão arterial pulmonar (risco relativo de 5,3; p = 0,036) foram preditoras de mortalidade hospitalar; e a proteína C-reativa pico (risco relativo de 1,8; p = 0,013) e a hemotransfusão (risco relativo de 8,3; p = 0,0009) de mortalidade em 1 ano. Aos 30 dias, 97% dos pacientes estavam em classe NYHA I/II e, em 1 ano, o número chegou a 96%. Conclusão: O implante de válvula aórtica por cateter foi realizado com alto índice de sucesso e baixa mortalidade. A hemotransfusão associou-se com maior mortalidade hospitalar e de 1 ano. Proteína C-reativa pico se associou com a mortalidade de 1 ano.

ABSTRACT

Fundamentos: A insuficiência cardíaca de etiologia chagásica (ICCh) parece ter maior mortalidade que a de outrascom disfunção sistólica. O teste cardiopulmonar de exercício (TCPE) é uma ferramenta de avaliação prognósticaainda pouco estudada na cardiopatia chagásica.Objetivo: Avaliar se o TCPE pode discriminar as diferenças prognósticas da ICCh em comparação às de etiologianão chagásica (ICNCh) e verificar quais das suas variáveis são preditoras independentes de mau prognóstico.Métodos: Análise retrospectiva de 21 pacientes com ICCh e 76 pacientes com ICNCh encaminhados ao TCPE, eseguidos quanto à sua mortalidade em dois anos.Resultados: No seguimento, houve óbito de 5 pacientes no grupo chagásico (GC) e 25 no grupo não chagásico(GNC). A curva de Kaplan-Meier não mostrou diferença na curva de sobrevida entre os grupos (p=0,43). Aregressão logística encontrou a potência circulatória como uma variável preditora independente para óbito paraambos os grupos, com uma razão de risco para o GC de 17,3 (IC95% 1,39-217,0; p=0,027) e no GNC de 4,8(IC95% 1,59-14,6; p=0,005). A curva ROC para esta variável encontrou uma área de 0,91 (IC95% 0,78-1,00; p=0,006)com um valor de corte ≤1 280 mmHg.mL.kg-1.min-1 no GC e uma área de 0,75 (IC95% 0,64-0,86; p<0,0001) com umvalor de corte de ≤1 245 mmHg.mL.kg-1.min-1 no GNC.Conclusão: A potência circulatória foi a variável associada à morte em ambos os grupos, e deve ser mais amplamenteutilizada como indicador de prognóstico na insuficiência cardíaca.


Background: Chagas heart failure (CHF) seems to have higher mortality than other systolic dysfunction conditions. Cardiopulmonaryexercise testing (CPET) is a prognostic assessment tool that is still little studied in Chagas heart disease.Objective: To assess whether CPET can discriminate the prognostic differences of CHF compared to non-Chagas heart failures(NCHF) and determine which of its variables are independent predictors of poor prognosis.Methods: Retrospective analysis of 21 patients with CHF and 76 patients with NCHF referred to CPET and followed up formortality in two years.Results: During follow-up, 5 patients died in the Chagas group (CG) and 25 in the non-Chagas group (NCG). The Kaplan-Meiercurve showed no difference in the survival curve between groups (p=0.43). Logistic regression found the circulatory power as anindependent predictor of death for both groups, with a hazard ratio for the CG of 17.3 (95% CI 1.39-217.0; p=0.027) and for theNCG of 4.8 (95% CI 1.59-14.6; p=0.005). The ROC curve for this variable found an area of 0.91 (95% CI 0.78-1.00; p=0.006) witha cutoff value ≤1280 mmHg.mL.kg-1.min-1 in the CG and an area of 0.75 (95% CI 0.64-0.86; p<0.0001) with a cutoff value of≤1245 mmHg.mL.kg-1.min-1 in the NCG.Conclusion: Circulatory power was the variable associated with death in both groups and should be more widely used as an indicatorof prognosis in heart failure.

ABSTRACT

Nos últimos dois anos, observamos diversas modificações na abordagem diagnóstica e terapêutica dos pacientes com Insuficiência Cardíaca aguda (IC aguda), o que nos motivou quanto à necessidade da realização de um sumário de atualização da II Diretriz Brasileira de Insuficiência Cardíaca Aguda de 2009. Na avaliação diagnóstica, o fluxograma diagnóstico foi simplificado e foi fortalecido o papel da avaliação clínica e ecocardiograma. Na avaliação clínico-hemodinâmica admissional, o ecocardiograma hemodinâmico ganhou destaque no auxilio da definição dessa condição no paciente com IC aguda na sala de emergência. Na avaliação prognóstica, os biomarcadores tiveram seu papel mais bem estabelecido, e a síndrome cardiorrenal teve seus critérios e valor prognóstico mais bem definidos. Os fluxogramas de abordagem terapêutica foram revistos, tornando-se mais simples e objetivos. Dentre os avanços na terapêutica medicamentosa destacam-se a segurança e a importância da manutenção ou introdução dos betabloqueadores na terapêutica admissional. A anticoagulação, de acordo com as novas evidências, ganha um espectro maior de indicações. O edema agudo de pulmão tem bem estabelecido os seus modelos hemodinâmicos de apresentação com suas distintas formas de abordagens terapêuticas, com novos níveis de indicação e evidência. No tratamento cirúrgico da IC aguda, a revascularização miocárdica, a abordagem das lesões mecânicas e o transplante cardíaco foram revistos e atualizados. Este sumário de atualização fortalece a II Diretriz Brasileira de Insuficiência Cardíaca Aguda por mantê-la atualizada e rejuvenescida. Todos os clínicos cardiologistas que lidam com pacientes com IC aguda encontrarão na diretriz e em seu sumário de atualização importantes instrumentos no auxílio da prática clínica para o melhor diagnóstico e tratamento de seus pacientes.


In the past two years we observed several changes in the diagnostic and therapeutic approach of patients with acute heart failure (acute HF), which led us to the need of performing a summary update of the II Brazilian Guidelines on Acute Heart Failure 2009. In the diagnostic evaluation, the diagnostic flowchart was simplified and the role of clinical assessment and echocardiography was enhanced. In the clinical-hemodynamic evaluation on admission, the hemodynamic echocardiography gained prominence as an aid to define this condition in patients with acute HF in the emergency room. In the prognostic evaluation, the role of biomarkers was better established and the criteria and prognostic value of the cardiorenal syndrome was better defined. The therapeutic approach flowcharts were revised, and are now simpler and more objective. Among the advances in drug therapy, the safety and importance of the maintenance or introduction of beta-blockers in the admission treatment are highlighted. Anticoagulation, according to new evidence, gained a wider range of indications. The presentation hemodynamic models of acute pulmonary edema were well established, with their different therapeutic approaches, as well as new levels of indication and evidence. In the surgical treatment of acute HF, CABG, the approach to mechanical lesions and heart transplantation were reviewed and updated. This update strengthens the II Brazilian Guidelines on Acute Heart Failure to keep it updated and refreshed. All clinical cardiologists who deal with patients with acute HF will find, in the guidelines and its summary, important tools to help them with the clinical practice for better diagnosis and treatment of their patients.

ABSTRACT

OBJETIVO: Analisar os resultados da cirurgia de revascularização miocárdica (CRVM) isolada com circulação extracorpórea em pacientes com idade > 70 anos em comparação àqueles com < 70 anos. MÉTODOS: Pacientes submetidos consecutivamente à CRVM isolada. Os pacientes foram agrupados em G1 (idade e" 70 anos) e G2 (idade < 70 anos). Os desfechos analisados foram letalidade hospitalar, infarto agudo miocárdio (IAM), acidente vascular encefálico (AVE), reoperação para revisão de hemostasia (RRH), necessidade de balão intra-aórtico (BIA), complicações respiratórias, insuficiência renal aguda (IRA), mediastinite, sepse, fibrilação atrial (FA) e bloqueio atrioventricular total (BAVT). RESULTADOS: Foram estudados 1033 pacientes, 257 (24,8%) do G1 e 776 (75,2%) do G2. A letalidade hospitalar foi significantemente maior no G1 quando comparado ao G2 (8,9% vs. 3,6%, P=0,001), enquanto a incidência de IAM foi semelhante (5,8% vs. 5,5%; P=0,87). Maior número de pacientes do G1 necessitou de RRH (12,1% vs. 6,1%; P=0,003). Da mesma forma, no G1 houve maior incidência de complicações respiratórias (21,4% vs. 9,1%; P<0,001), mediastinite (5,1% vs. 1,9%; P=0,013), AVE (3,9% vs. 1,3%; P=0,016), IRA (7,8% vs. 1,3%, P<0,001), sepse (3,9% vs. 1,9%; P=0,003), fibrilação atrial (15,6% vs. 9,8%; P=0,016) e BAVT (3,5% vs. 1,2%; P=0,023) do que o G2. Não houve diferença significante na necessidade de BIA. Na análise regressão logística multivariada "forward stepwise", a idade >70 anos foi fator preditivo independente para maior letalidade operatória (P=0,004) e para RRH (P=0,002), sepse (P=0,002), complicações respiratórias (P<0,001), mediastinite (P=0,016), AVE (P=0,029), IRA (P<0,001), FA (P=0,021) e BAVT (P=0,031) no pós-operatório. CONCLUSÃO: Este estudo sugere que pacientes com idade > 70 anos estão sob maior risco de morte e outras complicações no pós-operatório de CRVM em comparação aos pacientes mais jovens.


OBJECTIVE: To analyze the results of isolated on-pump coronary artery bypass graft surgery (CABG) in patients >70 years-old in comparison to patients <70 years-old. METHODS: Patients undergoing isolated CABG were selected for the study. The patients were grouped in G1 (age > 70 years-old) and G2 (age <70 years-old). The endpoints were in-hospital mortality, acute myocardial infarction (AMI), stroke, reexploration for bleeding, intra-aortic balloon for circulatory shock, respiratory complications, acute renal failure, mediastinitis, sepsis, atrial fibrillation, and complete atrioventricular block (CAVB). RESULTS: 1,033 patients were included, 257 (24.8%) in G1 and 776 (75.2%) in G2. Patients in G1 were more likely to have in-hospital mortality than G2 (8.9% vs. 3.6%, respectively; P=0.001), while the incidence of AMI was similar (5.8% vs. 5.5%; P=0.87) than G2. More patients in G1 had re-exploration for bleeding (12.1% vs. 6.1%; P=0.003). G1 had more incidence of respiratory complications (21.4% vs. 9.1%; P<0.001), mediastinitis (5.1% vs. 1.9%; P=0.013), stroke (3.9% vs. 1.3%; P=0.016), acute renal failure (7.8% vs. 1.3%; P<0.001), sepsis (3.9% vs. 1.9%;P=0.003), atrial fibrillation (15.6% vs. 9.8%; P=0.016), and CAVB (3.5% vs. 1.2%; P=0.023) than G2. There was no significant difference in the use of intra-aortic balloon. In the forward stepwise multivariate logistic regression analysis age > 70-year-old was an independent predictive factor for higher in-hospital mortality (P=0.004), reexploration for bleeding (P=0.002), sepsis (P=0.002), respiratory complications (P<0.001), mediastinitis (P=0.016), stroke (P=0.029), acute renal failure (P<0.001), atrial fibrillation (P=0.021) and CAVB (P=0.031). CONCLUSION: This study suggests that patients > 70 years-old were at increased risk of death and other complications in the CABG's postoperative period in comparison to younger patients.

ABSTRACT

OBJETIVO: Avaliar a eficácia do tratamento cirúrgico da fibrilação atrial (FA) utilizando ablação com radiofrequência bipolar durante cirurgia cardíaca de procedimentos mitrais de etiologia reumática. MÉTODOS: Foram avaliados, retrospectivamente, os prontuários e exames de 53 pacientes submetidos à cirurgia valvar mitral, com ou sem cirurgia tricúspide ou aórtica associada, em que foi realizada ablação de FA utilizando radiofrequência bipolar. Trinta e quatro (64 por cento) pacientes eram mulheres e a idade variou de 27 a 72 anos (média: 49,3 anos ± 10,7 anos). O tempo médio de FA relatado foi de 41 meses (variou de 3 a 192 meses). O tipo de FA apresentado foi: paroxística em oito pacientes, persistente em três, permanente em 42. O átrio esquerdo apresentava tamanho médio de 52,9 ± 8,5 mm. As cirurgias realizadas foram: 47 trocas de valva mitral e seis plastias mitrais. O seguimento eletrocardiográfico foi completo em 83 por cento dos pacientes, ao final de 14 meses. Informações adicionais oriundas de Holter 24h foram exploradas. RESULTADOS: Ocorreram sete (13 por cento) óbitos per-operatórios e a sobrevida após 14 meses foi de 87 por cento. Os ritmos cardíacos encontrados após um ano de cirurgia foram: sinusal em 25 (66 por cento) pacientes, FA em sete (18 por cento), Flutter em cinco (13 por cento), Juncional em um (3 por cento). CONCLUSÃO: O uso de radiofrequência bipolar para tratamento de FA em pacientes submetidos à cirurgia valvar mitral de origem reumática é efetivo no controle da arritmia em 68 por cento dos pacientes, após 14 meses.


OBJECTIVE: To analyze the effectiveness of surgical treatment of atrial fibrillation (AF) using bipolar radiofrequency ablation during mitral valve procedures of rheumatic etiology in heart surgery. METHODS: We retrospectively reviewed medical registries of 53 patients submitted to atrial ablation with bipolar radiofrequency energy during mitral valve surgery. Thirty four (64 percent) patients were women and the age varied from 27 to 72 years old (average: 49.3 ± 10.7 years). Aortic and/or tricuspid procedures were also present in 36 (68 percent) patients. Average time of reported atrial fibrillation was 41 months (from 3 to 192 months). Type of AF was classified as: paroxysmal in 8 patients, persistent in 3, permanent in 42. Left atrium had an average size of 52.9 ± 8.5 mm. The surgeries in these series were: 47 mitral valve replacements and 6 mitral valve repairs. Eletrocardiografic follow up was 83 percent complete in 14 months. Data from 24h Holter were explored. RESULTS: Seven (13 percent) perioperative deaths were observed and survival after 14 months was 87 percent. Observed heart rhythm after 1 year of surgery was sinus rhythm in 25 (66 percent) patients, AF in 7 (18 percent), flutter in 7 (13 percent), junctional in 1 (3 percent). CONCLUSION: Bipolar radiofrequency ablation in patients submitted to mitral valve surgery of rheumatic etiology is effective in converting to sinus rhythm in 68 percent of patients after 14 months.

ABSTRACT

Fundamentos : Admite-se que os riscos de complicações pós-operatórias sejam maiores na angina instável pós-infarto.Objetivo: Verificar se a angina instável (AI) pósinfarto (classe C de Braunwald) aumenta o risco de eventos cardiovasculares maiores (ECMA) nacirurgia de revascularização miocárdica (CRVM) em comparação às síndromes coronarianas estáveis. Métodos: Em pacientes submetidos consecutivamenteà CRVM isolada, durante um período de dois anos, comparou-se a incidência de ECMA [morte, infarto agudo do miocárdio com onda Q (IAM) e acidentevascular encefálico (AVE)] entre aqueles com síndromes coronarianas estáveis (G1) e aqueles com AI classe B (G2) e AI classe C (G3) de Braunwald.Resultados: De 333 pacientes operados no período, 238 (71,0%) compunham o G1, 56 (17,0%) o G2 e 39 (12,0%) o G3. Mais pacientes dos G2 e G3apresentavam DPOC (12,5% e 10,0% vs 2,9%, p=0,005) e necessidade de cirurgia de urgência/emergência (18,0% e 33% vs 0,4%; p=0,0001) do que o G1. Não houve diferença significativa na morte hospitalar (4,6%, 8,9% e 5,1%; p=0,45), IAMQ (2,9%,3,6% e 5,1%; p=0,69) e AVE (5,5%, 0%, e 5,1%; p=0,17) ou ECMA (10,9%, 12,5% e 12,8%; p=0,85) entre osG1, G2 e G3, respectivamente.Conclusão: Este estudo sugere que a angina instável pós-IAM não aumenta o risco de eventos cardiovasculares maiores na CRVM em comparaçãoàs síndromes coronarianas estáveis.


Background: It is assumed that post-infarction unstable angina increases the risk of post-operative complications.Objective: To ascertain whether post-infarction unstable angina (Braunwald class C) increases the risk of major cardiovascular events (MACE) for coronary artery bypass surgery (CABG) in comparison to stable coronary syndromes. Methods: In patients undergoing individual CABGconsecutively for a period of two years, the incidence of MACE (hospital mortality, non-fatal Q-wave myocardial infarction [AMI], and stroke) wascompared for patients with stable coronary syndromes (G1) and patients with class B unstable angina (G2),and patients with Braunwald class C unstable angina (G3). Results: Among 333 patients operated during thatperiod, 238 (71%) belonged to G1, 56 (17%) to G2, and 39 (12%) to G3. More G2 and G3 patients presentedCOPD (12.5% and 10.0% vs 2.9%, p=0.005), and the need for emergency / urgent surgery (18.0% and 33.0%vs 0.4%; p=0.0001) than in G1. No significant difference appeared in hospital mortality (4.6%, 8.9%, and 5.1%; p=0.45), non-fatal AMI (2.9%, 3.6%, and 5.1%; p=0.69), and stroke (5.5%, 0%, and 5.1%; p=0.17) or MACE(10.9%, 12.5%, and 12.8%; p=0.85) among G1, G2, and G3 respectively.Conclusion: This study suggests that post-infarction unstable angina did not increase the risk of MACE in CABG compared to stable coronary syndromes.

ABSTRACT

FUNDAMENTO: O tratamento da fibrilação atrial com dispositivo de ablação de tecidos por radiofrequência bipolar em concomitância à cirurgia cardíaca tem se mostrado método eficaz no tratamento desta arritmia. OBJETIVO: Descrever a experiência inicial do Instituto Nacional de Cardiologia no tratamento cirúrgico da fibrilação atrial com uso de dispositivo de radiofrequência bipolar em pacientes submetidos à cirurgia cardíaca, relatando o resultado de acompanhamento pós-operatório de um ano. MÉTODOS: Entre janeiro de 2008 e março de 2009, 47 pacientes (36 mulheres) consecutivos, com idade média de 53,7 ± 10,6 anos, apresentando fibrilação atrial por um período médio de 34,6 meses (3 a 192 meses) foram submetidos à ablação cirúrgica desta arritmia, por radiofrequência bipolar, durante o procedimento que motivou a indicação da cirurgia. Oito apresentavam fibrilação atrial intermitente e 39, contínua. Oitenta e um por cento foram submetidos à cirurgia valvar como procedimento principal. Esta é uma análise retrospectiva, observacional, com avaliação de um ano de pós-operatório das variáveis clínicas e de Holter 24 h. RESULTADOS: Dos 47 pacientes, 40 sobreviveram um ano. Desses, 33 foram submetidos a Holter 24 h, em um intervalo médio de 401 dias após a cirurgia. Encontrou-se a seguinte distribuição de ritmos: 24 (73 por cento) sinusal, 5 (15 por cento) fibrilação atrial, três (9 por cento) Flutter atrial e um (3 por cento) ritmo juncional. Foram observados dois acidentes vasculares encefálicos, sendo um associado à arritmia supraventricular. CONCLUSÃO: A ablação cirúrgica de fibrilação atrial com dispositivo de radiofrequência bipolar concomitante à cirurgia cardíaca é método eficaz para o tratamento desta arritmia.


BACKGROUND: Atrial fibrillation with tissue ablation device through bipolar radiofrequency in conjunction with cardiac surgery has proven to be an effective method to treat this arrhythmia. OBJECTIVE: Describe the initial experience of the Instituto Nacional de Cardiologia in the surgical treatment of atrial fibrillation using bipolar radiofrequency device in patients undergoing cardiac surgery, reporting the results of postoperative follow-up of one year. METHODS: Between January 2008 and March 2009, 47 consecutive patients (36 women), with mean age of 53.7 ± 10.6 years, with atrial fibrillation for a mean period of 34.6 months (3-192 months) underwent surgical ablation of this arrhythmia, through bipolar radiofrequency during the procedure which led to the indication of surgery. Eight of them showed intermittent atrial fibrillation and 39, continued. Eighty-one percent underwent valve surgery as the main procedure. This is a one-year postoperative retrospective, observational evaluation of clinical variables and 24-h Holter. RESULTS: Out of the 47 patients, 40 survived one year. Out of these, 33 underwent 24 h Holter, at an average interval of 401 days after the surgery. The following rhythm distribution was found: 24 (73.0 percent) sinus, five (15.0 percent) atrial fibrillation, three (9.0 percent) atrial Flutter and one (3.0 percent) junctional rhythm. Two cerebrovascular accidents were observed, one of which was associated with supraventricular arrhythmia. CONCLUSION: Surgical ablation of atrial fibrillation with bipolar radiofrequency device concomitant with cardiac surgery is an effective method for treating this arrhythmia.

ABSTRACT

Fundamentos: A cirurgia de revascularização miocárdica (CRVM) promove uma melhora da sobrevivência de pacientes com doença arterial coronariana (DAC) e disfunção ventricular esquerda (DFVE).Objetivo: Analisar se a CRVM é capaz de igualar a sobrevivência de pacientes portadores de doença arterialcoronariana com DFVE e sem DFVE. Métodos: Pacientes (n=259) que sobreviveram à CRVM realizada entre 1/10/2001 e 31/1/2004 foramacompanhados por três anos após a cirurgia. A DFVE foi caracterizada por uma fração de ejeção do ventrículoesquerdo (FE) ≤40%. Foram formados dois grupos de acordo com a presença (G1; n=45) ou não (G2; n=214) deDFVE. Resultados: O G1 apresentava mais síndromes coronarianas agudas antes da CRVM (64,4% vs 40,2%;p=0,005); insuficiência cardíaca congestiva (17,8% vs 1,9%; p<0,0001); história prévia de infarto agudo do miocárdio (80% vs 60,3%; p=0,016) e doença pulmonarobstrutiva crônica (11,1% vs 2,3%; p=0,016) do que o G2. A sobrevivência cumulativa em três anos de seguimentofoi significantemente menor no G1 do que no G2 (88,8±4,7% vs 95,7±1,3%, respectivamente; p=0,05). ADFVE, no entanto, não foi fator independente para a menor sobrevivência no seguimento (p=0,119).Conclusão: Este estudo sugere que a CRVM não é capaz de igualar a sobrevivência de pacientes portadores de DAC e DFVE com a de pacientes com DAC sem DFVE.


Background: Coronary artery bypass graft (CABG) surgery prolongs the survival of patients with coronary artery disease (CAD) and left ventriculardysfunction (LVD). Objective: To verify whether CABG can match the survival times of CAD patients with and without LVD. Methods: 259 patients who survived CAGB performed between October 1, 2001 and January 31, 2004 were followed up for three years, with LVD characterized by a left ventricle ejection fraction of ≤40%. Two groups of patients were established, based on the presence (G1; n=45) or absence (G2; n=214) of LVD. Results: G1 patients presented more acute coronarysyndromes before CABG (64.4% vs 40.2%; p=0.005), congestive heart failure (17.8% vs 1.9%; p<0.0001),previous history of acute myocardial infarction (80% vs 60.3%; p=0.016), and chronic obstructive pulmonarydisease (11.1% vs 2.3%; p=0.016) than G2. The threeyear cumulative survival rate was significantly lowerin G1 than in G2 (88.8±4.7% vs 95.7±1.3%, respectively; p=0.05). However, LVD was not an independent factor for shorter survival times during the follow-up period (p=0.119).Conclusion: this study suggests that CABG is unable to match the survival of patients with CAD and LVD to the survival of patients with CAD without LVD.
