Use of Quality of Life in Cardiovascular Surgery in Coronary Artery Bypass Grafting: Validation, Reproducibility, and Quality of Life in One Year of Follow-Up.

BACKGROUND: The objectives of this study are to validate the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire and to observe the evolution of quality of life in the first year of postoperative follow-up of patients who underwent coronary artery bypass grafting (CABG). METHODS: This was a prospective observational study of patients undergoing CABG from July 2016 to June 2017 who survived and answered the QLCS with 1, 6, and 12 months of follow-up. Validation was evaluated for internal consistency by Cronbach's alpha, test-retest reproducibility by correlation coefficient of concordance, and accuracy for interrater reliability by the kappa statistic. The nonparametric analysis of variance test was used for analysis of repeated measures, during follow-up, of the QLCS was considered significant at p < 0.05. RESULTS: Included were 360 patients, with a mean age of 63 years; 72% were men. Cronbach's alpha was 0.82, demonstrating adequate internal consistency. The correlation coefficient of concordance was 0.93 and accuracy 0.99, showing good precision and accuracy. The kappa statistic for questions ranged from 0.58 to 0.78, which ensures a moderate reproducibility. Scores of the QLCS in patients undergoing CABG of 17.69, 18.82, and 19.52 were found at 1, 6, and 12 months, respectively. Thus there was a progressive improvement in quality of life over the first year of follow-up (p < 0.0001). CONCLUSIONS: The QLCS proved to be a good questionnaire in this population, with adequate internal consistency and moderate reproducibility. Its use revealed a progressive and significant improvement in the quality of life of patients undergoing CABG.

Quality of Life in Cardiovascular Surgery: Elaboration and Initial Internal Validation of a Quality of Life Questionnaire.

OBJECTIVE: Elaboration and internal validation of the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire adapted to the reality of Brazilian cardiovascular surgery. METHODS: Cross-sectional pilot study of a prospective cohort included in the Documentation and Surgical Registry Center (CEDREC) for internal validation of the QLCS questionnaire. Four hundred forty-five patients submitted to cardiovascular surgery and who answered a QLCS questionnaire 30 days after hospital discharge were included. It was applied via telephone. To verify the questions' internal consistency, Cronbach's alpha was used. The total QLCS score was calculated as the sum of 5 questions, ranging from 5 to 25 points. Mann-U-Whitney test was used to relate the symptoms with the quality of life (QoL). Level of significance was 5%. RESULTS: After 30 days of surgery, about 95% of the patients had already returned to normal routine and 19% of them were already performing physical activity. In the evaluation of the QLCS's internal consistency, a Cronbach's alpha of 0.74 was found, suggesting that this was probably an adequate questionnaire to evaluate QoL in this population. In the comparison between the presence and absence of symptoms and the median of QoL, the presence of pain at the incision (P=0.002), chest pain (P<0.001), shortness of breath (P<0.001), and return to physical activity (P<0.001) were statistically significant. CONCLUSION: The process of elaboration and validation of questionnaires includes a series of steps. The QLCS questionnaire is probably an adequate tool for the evaluation of QoL in the postoperative patient of cardiovascular surgery, in this first stage of internal validation.

Mortality Predictors in the Surgical Treatment of Active Infective Endocarditis.

INTRODUCTION: Active infective endocarditis is associated with high morbidity and mortality. Surgery is indicated in high-risk conditions, and the main determinants of mortality in surgical treatment should be evaluated. OBJECTIVE: To identify mortality predictors in the surgical treatment of active infective endocarditis in a long-term follow-up. METHODS: This prospective observational study involved 88 consecutive patients diagnosed with active infective endocarditis, who underwent surgery between January 2005 and December 2015. Fifty-eight (65.9%) patients were male, the mean age was 50.87±16.15 years. A total of 31 (35.2%) patients had a history of rheumatic fever; 48 (54.5%) had had heart surgery with prosthetic valve implantation; 45 (93.8%) had biological prosthetic valve endocarditis and 3 (6.3%) mechanical prosthetic valve; 40 (45.5%) patients had the disease in their native valve. The mean EuroSCORE II was 8.9±6.5%, and the main surgical indication was refractory heart failure in 38 (43.2%) patients. A total of 68 bioprosthesis (36 aortic, 32 mitral) and 29 mechanical prostheses (12 aortic, 17 mitral) were implanted and three mitral valve plasties performed. A total of 25 (28.4%) patients underwent double or triple valve procedures. Aortic annulus reconstruction by abscess was performed in 18 (20.5%) and six (6.81%) patients had combined procedure. The mean surgery time was 359±97.6 minutes. RESULTS: The overall survival in up to a 10-year follow-up period was 79.5%. In the univariate analysis, the main mortality predictors were positive blood cultures (P=0.003), presence of typical microorganisms (P=0.008), most frequently Streptococcus viridans (12 cases; 25%); C-reactive protein (hazard ratio [HR] 1.034, 95% confidence interval [CI] 1.000 to 1.070, P=0.04); creatinine clearance (HR 0.977, 95% CI 0.962 to 0.993, P=0.005); length of surgery: every five minutes multiplies the chance of death 1.005-fold (HR 1.005, 95% CI 1.001 to 1.009, P=0.0307); age (HR 1.060, 95% CI 1.026 to 1.096, P=0.001); and EuroSCORE II (HR 1.089, 95% CI 1.030 to 1.151, P=0.003). CONCLUSION: A positive blood culture with typical microorganism, C-reactive protein, age, EuroSCORE II, total surgical time and the presence of postoperative complications were the major predictors of mortality and significantly impacted survival in up to a 10-year follow-up period.

Quality of Life in Cardiac Surgery (QLCS): elaboração e validação interna de um questionário de qualidade de vida para a realidade da cirurgia cardíaca / Quality of Life in Cardiac Surgery (QLCS): elaboration and internal validation of a quality of life questionnaire for the reality of cardiac surgery

INTRODUÇÃO: A qualidade de vida (QV) é definida como a percepção do indivíduo de sua posição na vida no contexto da cultura e sistema de valores nos quais ele vive e em relação aos seus objetivos, expectativas, padrões e preocupações. Para avaliar a QV, pode optar por uso de questionários genéricos, que não especificam a doença em si, ou questionários específicos, desenvolvidos para determinada patologia. OBJETIVO: Elaborar e validar um questionário adaptado à realidade da cirurgia cardíaca brasileira e de fácil aplicação, que possa ser realizado por contato telefônico, tomando com base os principais questionários já existentes. MÉTODOS: Estudo transversal de uma coorte prospectiva incluída no Centro de Documentação e Registro Cirúrgico (CEDREC) de um hospital especializado em cardiologia. Foram incluídos 445 pacientes submetidos à cirurgia cardíaca de julho de 2016 a outubro de 2017, que possuíam questionário de QV respondido 30 dias após alta hospitalar. Aplicou-se um questionário por contato telefônico composto de 21 questões, sendo 16 para avaliação da aderência medicamentosa, sintomas e complicações, e 5 para avaliação da qualidade de vida (QLCS). O questionário QLCS foi elaborado por um conjunto de médicos especialistas. Para verificar a consistência interna das questões foi utilizado o alfa de Crobanch. Foi calculado o escore total de QV sendo a soma das 5 questões da QV variando de 5 a 25 pontos. Para correlacionar os sintomas com a QV foi utilizado o teste de Mann-Whitney. O nível de significância adotado foi de 5%. RESULTADOS: Após 30 dias da cirurgia 35% apresentavam dor na incisão, 17% infecção na ferida, 23% dor no peito, 22% falta de ar, 1% desmaio, 5% palpitação, 43% outros sintomas. Sendo que 95% dos pacientes já tinham retornado a rotina habitual e 19% já estavam realizando atividade física. Na avaliação na consistência interna do QLCS encontrou-se um alfa de Crobanch de 0,74, comprovando ser um bom questionário para avaliar QV nessa população. Na correlação dos sintomas com a QV, observou-se que a presença de dor na incisão (P=0,002), dor no peito... (AU)

Long-term Mortality Predictors in Patients with Small Aortic Annulus Undergoing Aortic Valve Replacement with a 19- or 21-mm Bioprosthesis.

Introduction: Replacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population. Objective: To evaluate the long-term mortality predictors in patients with a small aortic annulus undergoing aortic valve replacement with a bioprosthesis. Methods: In this retrospective observational study, a total of 101 patients undergoing aortic valve replacement from January 2000 to December 2010 were studied. There were 81 (80.19%) women with a mean age of 52.81±18.4 years. Severe aortic stenosis was the main indication for surgery in 54 (53.4%) patients. Posterior annulus enlargement was performed in 16 (15.8%) patients. Overall, 54 (53.41%) patients underwent concomitant surgery: 28 (27.5%) underwent mitral valve replacement, and 13 (12.7%) underwent coronary artery bypass graft surgery. Results: Mean valve index was 0.82±0.08 cm(2)/m(2). Overall, 17 (16.83%) patients had a valve index lower than 0.75 cm(2)/m(2), without statistical significance for mortality (P=0.12). The overall 10-year survival rate was 83.17%. The rate for patients who underwent isolated aortic valve replacement was 91.3% and 73.1% (P=0.02) for patients who underwent concomitant surgery. In the univariate analysis, the main predictors of mortality were preoperative ejection fraction (P=0.02; HR 0.01) and EuroSCORE II results (P=0.00000042; HR 1.13). In the multivariate analysis, the main predictors of mortality were age (P=0.01, HR 1.04) and concomitant surgery (P=0.01, HR 5.04). Those relationships were statistically significant. Conclusion: A valve index of < 0.75 cm(2)/m(2) did not affect 10-year survival. However, concomitant surgery and age significantly affected mortality.

Effects of skeletonized versus pedicled radial artery on postoperative graft patency and flow.

BACKGROUND: Radial artery (RA) was the second arterial graft introduced in clinical practice for myocardial revascularization. The skeletonization technique of the left internal thoracic artery (LITA) may actually change the graft's flow capacity with potential advantages. This leads to the assumption that the behavior of the RA, as a coronary graft, is similar to that of the LITA, when skeletonized. OBJECTIVE: This study evaluated 'free' aortic-coronary radial artery (RA) grafts, whether skeletonized or with adjacent tissues. METHODS: A prospective randomized study comparing 40 patients distributed into two groups was conducted. In group I, we used skeletonized radial arteries (20 patients), and in group II, we used radial arteries with adjacent tissues (20 patients). After the surgical procedure, patients underwent flow velocity measurements. RESULTS: The main surgical variables were: RA internal diameter, RA length, and free blood flow in the radial artery. The mean RA graft diameters as calculated using quantitative angiography in the immediate postoperative period were similar, as well as the flow velocity measurement variables. On the other hand, coronary cineangiography showed the presence of occlusion in one RA graft and stenosis in five RA grafts in GII, while GI presented stenosis in only one RA graft (p = 0.045). CONCLUSION: These results show that the morphological and pathological features, as well as the hemodynamic performance of the free radial artery grafts, whether prepared in a skeletonized manner or with adjacent tissues, are similar. However, a larger number of non-obstructive lesions may be observed when RA is prepared with adjacent tissues.

Efeitos da Esqueletização em Comparação com a Manutenção do Pedículo da Artéria Radial sobre a Patência e Fluxo Pós-Operatórios do Enxerto / Effects of Skeletonized versus Pedicled Radial Artery on Postoperative Graft Patency and Flow

Fundamento: O enxerto de artéria radial (AR) foi o segundo enxerto arterial a ser introduzido na prática clínica para revascularização miocárdica. A técnica de esqueletização da artéria torácica interna esquerda (ATIE) pode, de fato, alterar a capacidade de fluxo do enxerto com potenciais vantagens, o que leva à suposição de que o comportamento da AR, como enxerto coronariano, seja semelhante ao da ATIE esqueletizada. Objetivo: Este estudo avaliou enxertos aortocoronários "livres" de AR, quer esqueletizados, quer com tecidos adjacentes. Métodos: Foi realizado um estudo prospectivo randomizado comparando 40 pacientes distribuídos em dois grupos. No grupo I, foram utilizadas artérias radiais esqueletizadas (20 pacientes), e no grupo II, artérias radiais com tecidos adjacentes (20 pacientes). Após o procedimento cirúrgico, os pacientes foram submetidos a medidas da velocidade de fluxo. Resultados: As principais variáveis cirúrgicas foram: diâmetro interno, comprimento e fluxo sanguíneo livre da AR. Os diâmetros médios dos enxertos de AR calculados através de angiografia quantitativa no pós-operatório imediato foram semelhantes, assim como as variáveis de medidas de velocidade de fluxo. Por outro lado, a cinecoronariografia mostrou a presença de oclusão em um enxerto de AR e estenose em cinco enxertos de AR no GII, enquanto que apenas um caso de estenose em um enxerto de AR no GI (p = 0,045). Conclusão: Os resultados mostram que tanto as características morfológicas e anatomopatológicas quanto o desempenho hemodinâmico dos enxertos livres de artéria radial, quer preparados de forma esqueletizada ou com tecidos adjacentes, são semelhantes. Entretanto, pode-se observar um maior número de lesões não obstrutivas quando a AR ...

Risk factors for pre, intra, and postoperative hospital mortality in patients undergoing aortic surgery.

OBJECTIVES: The primary objective was to identify predictors of hospital mortality in patients undergoing aortic surgery. The secondary objective was to identify factors associated with clinical outcome composed hospital (death, bleeding, neurologic complications or ventricular dysfunction). METHODS: A cross-sectional design with longitudinal component. Through chart review, 257 patients were included. Inclusion criteria were: aortic dissection Stanford type A and ascending aortic aneurysm. Exclusion criteria were acute aortic dissection, of any kind, and no aortic aneurysm involving the ascending segment. Variables assessed: demographics, preoperative factors, intraoperative and postoperative. RESULTS: Variables with increased risk of hospital mortality (OR, 95% CI, P value): black ethnicity (6.8, 1.54-30.2; 0.04), cerebrovascular disease (10.5, 1.12-98.7; 0.04), hemopericardium (35.1, 3.73-330.2; 0.002), Cabrol operation (9.9, 1.47-66.36; 0.019), CABG simultaneous (4.4; 1.31 to 15.06; 0.017), bleeding (5.72, 1.29-25.29; 0.021) and cardiopulmonary bypass (CPB) time [min] (1.016; 1.0071.026; 0.001). Thoracic pain was associated with reduced risk of hospital death (0.27, 0.08-0.94, 0.04). Variables with increased risk of hospital clinical outcome compound were: use of antifibrinolytic (3.2, 1.65-6.27; 0.0006), renal complications (7.4, 1.52-36.0; 0.013), pulmonary complications (3.7, 1.58.8, 0.004), EuroScore (1.23; 1.08-1.41; 0.003) and CPB time [min] (1.01; 1.00 to 1.02; 0.027). CONCLUSION: Ethnicity black, cerebrovascular disease, hemopericardium, Cabrol operation, CABG simultaneous, hemostasis review and CPB time was associated with increased risk of hospital death. Chest pain was associated with reduced risk of hospital death. Use of antifibrinolytic, renal complications, pulmonary complications, EuroScore and CPB time were associated with clinical outcome hospital compound.

RESULTADOS: Variáveis com risco aumentado de óbito hospitalar (RC; IC95%; P valor): etnia negra (6,8; 1,54 30,2; 0,04), doença cerebrovascular (10,5; 1,12-98,7; 0,04), hemopericárdio (35,1; 3,73-330,2; 0,002), operação de Cabrol (9,9; 1,47-66,36; 0,019), cirurgia de revascularização miocárdica simultânea (4,4; 1,31-15,06; 0,017), revisão de hemostasia (5,72; 1,29-25,29; 0,021) e circulação extracorpórea (CEC) [min] (1,016; 1,007-1,026; 0,001). Dor torácica associou-se com risco reduzido de óbito hospitalar (0,27; 0,08-0,94; 0,04). Variáveis com risco aumentado do desfecho clínico composto hospitalar foram: uso de antifibrinolítico (3,2; 1,65-6,27; 0,0006), complicação renal (7,4; 1,52-36,0; 0,013), complicação pulmonar (3,7; 1,5-8,8; 0,004), EuroScore (1,23; 1,08-1,41; 0,003) e tempo de CEC [min] (1,01; 1,00-1,02; 0,027). CONCLUSÃO: Etnia negra, doença cerebrovascular, hemopericárcio, operação de Cabrol, revascularização miocárdica simultânea, revisão de hemostasia e tempo de CEC associaram-se com risco aumentado de óbito hospitalar. Dor torácica associou-se com risco reduzido de óbito hospitalar. Uso de antifibrinolítico, complicação renal, complicação pulmonar, EuroScore e tempo de CEC associaram-se ao desfecho clínico composto hospitalar.

OBJECTIVES: The primary objective was to identify predictors of hospital mortality in patients undergoing aortic surgery. The secondary objective was to identify factors associated with clinical outcome composed hospital (death, bleeding, neurologic complications or ventricular dysfunction). METHODS: A cross-sectional design with longitudinal component. Through chart review, 257 patients were included. Inclusion criteria were: aortic dissection Stanford type A and ascending aortic aneurysm. Exclusion criteria were acute aortic dissection, of any kind, and no aortic aneurysm involving the ascending segment. Variables assessed: demographics, preoperative factors, intraoperative and postoperative. RESULTS: Variables with increased risk of hospital mortality (OR, 95% CI, P value): black ethnicity (6.8, 1.54-30.2; 0.04), cerebrovascular disease (10.5, 1.12-98.7; 0.04), hemopericardium (35.1, 3.73-330.2; 0.002), Cabrol operation (9.9, 1.47-66.36; 0.019), CABG simultaneous (4.4; 1.31 to 15.06; 0.017), bleeding (5.72, 1.29-25.29; 0.021) and cardiopulmonary bypass (CPB) time [min] (1.016; 1.0071.026; 0.001). Thoracic pain was associated with reduced risk of hospital death (0.27, 0.08-0.94, 0.04). Variables with increased risk of hospital clinical outcome compound were: use of antifibrinolytic (3.2, 1.65-6.27; 0.0006), renal complications (7.4, 1.52-36.0; 0.013), pulmonary complications (3.7, 1.58.8, 0.004), EuroScore (1.23; 1.08-1.41; 0.003) and CPB time [min] (1.01; 1.00 to 1.02; 0.027). CONCLUSION: Ethnicity black, cerebrovascular disease, hemopericardium, Cabrol operation, CABG simultaneous, hemostasis review and CPB time was associated with increased risk of hospital death. Chest pain was associated with reduced risk of hospital death. Use of antifibrinolytic, renal complications, pulmonary complications, EuroScore and CPB time were associated with clinical outcome hospital compound.
