    Age influences outcomes in 70-year or older patients undergoing isolated coronary artery bypass graft surgery
    (Revista Brasileira de Cirurgia Cardiovascular, 2012) Rocha, Antônio Sergio C. da; Pittella, Felipe; De Lorenzo, Andrea; Barzan, Valmir; Colafranceschi, Alexandre Siciliano; Brito, José Oscar R.; Mattos, Marco Antonio de; Silva, Paulo Roberto Dutra da
    Objetivo: Analisar os resultados da cirurgia de revascularização miocárdica (CRVM) isolada com circulação extracorpórea em pacientes com idade ³ 70 anos em comparação àqueles com < 70 anos. Métodos: Pacientes submetidos consecutivamente à CRVM isolada. Os pacientes foram agrupados em G1 (idade³ 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 ³ 70 anos foi fator preditivo independente para maior.

    Outcomes of patients with left main coronary artery disease undergoing medical or surgical treatment: a propensity- matched analysis
    (Coronary Artery Disease, 2011) De Lorenzo, Andrea; Tura, Bernardo; Bassan, Fernando; Pittella, Felipe; Rocha, Antonio Sergio C
    Objective: To evaluate the outcomes of patients with significant (≥ 50%) left main coronary artery disease (LMCAD) undergoing medical treatment (MT) or coronary artery bypass grafting surgery (CABG). Methods: A total of 181 patients with significant LMCAD were followed for 4 ± 2 years. MT was done when patients refused CABG or because of either thin native vessels or high clinical risk. Events were defined as all-cause death, myocardial infarction, percutaneous coronary intervention, or subsequent CABG. Logistic regression analysis was used to identify independent predictors of death. A propensity score was created to compare outcomes of patients from the two treatment groups. Results: CABG was performed in 78.5% of the patients. Overall, there were no significant differences in the incidences of death or other events between treatment groups. In patients with normal left ventricular (LV) function (ejection fraction, ≥ 45%), there were no significant differences in event rates with MT or CABG (death, 7.7 vs. 12.1%; myocardial infarction, 0 vs. 1.9%; percutaneous coronary intervention, 3.8 vs. 5.6%). For patients with LV dysfunction, death was more frequent with MT than with CABG (53.8 vs. 22.9%, P<0.001), whereas the incidence of other events was not statistically different. Age and LV dysfunction, but not treatment type, were independent predictors of death. When comparing propensity-matched patients from both treatment groups, there was also no difference in survival. Conclusion: Patients with 50% or more LMCAD and LV dysfunction had increased survival with CABG. However, outcomes of patients with 50% or more LMCAD and normal LV function were not significantly different with either MT or CABG.
