RESUMEN
OBJECTIVE: To develop and validate a predictive model utilizing machine-learning techniques for estimating the length of hospital stay among patients who underwent coronary artery bypass grafting. METHODS: Three machine learning models (random forest, extreme gradient boosting and neural networks) and three traditional regression models (Poisson regression, linear regression, negative binomial regression) were trained in a dataset of 9,584 patients who underwent coronary artery bypass grafting between January 2017 and December 2021. The data were collected from hospital discharges from 133 centers in Brazil. Algorithms were ranked by calculating the root mean squared logarithmic error (RMSLE). The top performing algorithm was validated in a never-before-seen database of 2,627 patients. We also developed a model with the top ten variables to improve usability. RESULTS: The random forest technique produced the model with the lowest error. The RMLSE was 0.412 (95%CI 0.405-0.419) on the training dataset and 0.454 (95%CI 0.441-0.468) on the validation dataset. Non-elective surgery, admission to a public hospital, heart failure, and age had the greatest impact on length of hospital stay. CONCLUSIONS: The predictive model can be used to generate length of hospital stay indices that could be used as markers of efficiency and identify patients with the potential for prolonged hospitalization, helping the institution in managing beds, scheduling surgeries, and allocating resources.

BACKGROUND: The analysis of indicators such as hospital readmission rates is crucial for improving the quality of services and management of hospital processes. OBJECTIVES: To identify the variables correlated with hospital readmission up to 30 days following coronary artery bypass grafting (CABG). METHODS: Cross-sectional cohort study by REPLICCAR II database (N=3,392) from June 2017 to June 2019. Retrospectively, 150 patients were analyzed to identify factors associated with hospital readmission within 30 days post-CABG using univariate and multivariate logistic regression. Analysis was conducted using software R, with a significance level of 0.05 and 95% confidence intervals. RESULTS: Out of 3,392 patients, 150 (4,42%0 were readmitted within 30 days post-discharge from CABG primarily due to infections (mediastinitis, surgical wounds, and sepsis) accounting for 52 cases (34.66%). Other causes included surgical complications (14/150, 9.33%) and pneumonia (13/150, 8.66%). The multivariate regression model identified an intercept (OR: 1.098, p<0.00001), sleep apnea (OR: 1.117, p=0.0165), cardiac arrhythmia (OR: 1.040, p=0.0712), and intra-aortic balloon pump use (OR: 1.068, p=0.0021) as predictors of the outcome, with an AUC of 0.70. CONCLUSION: 4.42% of patients were readmitted post-CABG, mainly due to infections. Factors such as sleep apnea (OR: 1.117, p=0.0165), cardiac arrhythmia (OR: 1.040, p=0.0712), and intra-aortic balloon pump use (OR: 1.068, p=0.0021) were predictors of readmission, with moderate risk discrimination (AUC: 0.70).
FUNDAMENTO: A análise de indicadores como taxa de readmissão hospitalar é crucial para aprimorar a qualidade dos serviços e gestão em processos hospitalares. OBJETIVO: Identificar as variáveis correlacionadas a readmissão hospitalar até 30 dias após cirurgia de revascularização miocárdica (CRM). MÉTODOS: Estudo de coorte transversal no banco de dados Registro Paulista de Cirurgia Cardiovascular II (REPLICCAR II)(N=3.392), de junho de 2017 a junho de 2019. Avaliaram-se retrospectivamente 150 pacientes para identificar os fatores correlacionados a readmissão hospitalar até 30 dias após-CRM via regressão logística univariada e multivariada. As análises foram realizadas no software R, com significância de 0,05 e intervalos de confiança de 95%. RESULTADOS: Cento e cinquenta pacientes foram readmitidos até 30 dias após a alta hospitalar de CRM (150/3.392, 4,42%) principalmente por infecções (mediastinite, ferida operatória e sepse) totalizando 52 casos (52/150, 34,66%), outras causas foram: complicações cirúrgicas (14/150, 9,33%) e pneumonia (13/150, 8,66%). Os preditores de readmissão identificados foram: O modelo de regressão multivariada apontou intercepto (OR: 1,098, p<0,00001), apneia do sono (OR: 1,117, p=0,0165), arritmia cardíaca (OR: 1,040, p=0,0712) e uso de balão intra-aórtico (OR: 1,068, p=0,0021) como preditores do desfecho, com uma AUC de 0,70. CONCLUSÃO: 4,42% dos pacientes foram readmitidos pós-CRM, principalmente por infecções. Fatores como apneia do sono (OR: 1,117, p=0,0165), arritmia cardíaca (OR: 1,040, p=0,0712) e uso de balão intra-aórtico (OR: 1,068, p=0,0021) foram preditores de readmissão, com uma discriminação de risco moderada (AUC: 0,70).

BACKGROUND: Identifying risk factors in cardiovascular surgery assists in predictability, resulting in optimization of outcomes and cost reduction. OBJECTIVE: This study aimed to identify preoperative and intraoperative risk predictors for prolonged hospitalization after coronary artery bypass grafting (CABG) surgery in the state of São Paulo, Brazil. METHODS: A cross-sectional analysis using data from the REPLICCAR II database, a prospective, consecutive, multicenter registry that included CABG surgeries performed between August 2017 and July 2019. The primary outcome was a prolonged hospital stay (PHS), defined as a postoperative period exceeding 14 days. Univariate and multivariate logistic regression analyses were performed to identify the predictors with significance set at p <0.05. RESULTS: The median age was 63 (57-70) years and 26.55% of patients were female. Among the 3703 patients analyzed, 228 (6.16%) had a PHS after CABG, with a median hospital stay of 17 (16-20) days. Predictors of PHS after CABG included age >60 years (OR 2.05; 95% CI 1.43-2.87; p<0.001); renal failure (OR 1.73; 95% CI 1.29-2.32; p <0.001) and intraoperative red blood cell transfusion (OR 1.32; 95% CI 1.07-2.06; p=0.01). CONCLUSION: Age >60 years, renal failure, and intraoperative red blood cell transfusion were independent predictors of PHS after CABG. The identification of these variables can help in multiprofessional strategic planning aimed to enhance results and resource utilization in the state of São Paulo.
FUNDAMENTO: A identificação de fatores de riscos na cirurgia cardiovascular auxilia na previsibilidade resultando na otimização de desfechos e redução de custos. OBJETIVO: Identificação dos preditores de risco pré e intraoperatórios para internação prolongada após cirurgia de revascularização do miocárdio (CRM) no Estado de São Paulo. MÉTODOS: Análise transversal no banco de dados REPLICCAR II, registro prospectivo, consecutivo, multicêntrico que incluiu cirurgias de revascularização miocárdica realizadas entre agosto de 2017 e julho de 2019. O desfecho principal foi o tempo de internação prolongado, definida como período de pós-operatório superior a 14 (quatorze) dias. Para a identificação dos preditores foram realizadas análises de regressão logística uni- e multivariada. Os valores de p menores de 0,05 foram considerados significativos. RESULTADOS: A mediana de idade foi de 63 (57-70) anos e 26,55% eram do sexo feminino. Dos 3703 pacientes analisados, 228 (6,16%) apresentaram longa permanência hospitalar (LPH) após a CRM e a mediana da internação foi de 17 (16-20) dias. Foram preditores da LPH após a CRM: idade >60 anos (OR 2,05; IC95% 1,43 - 2,87; p<0,001); insuficiência renal (OR 1,73; IC95% 1,29 - 2,32; p<0,001) e transfusão de hemácias no intraoperatório (OR 1,32; IC 1,07 - 2,06; p=0,01). CONCLUSÃO: Nesta análise, a idade > 60 anos, insuficiência renal e a transfusão de hemácias no intraoperatório foram preditores independentes de LPH após a CRM. A identificação destas variáveis pode ajudar no planejamento estratégico multiprofissional visando melhoria de resultados e otimização de recursos no estado de São Paulo.

INTRODUCCIÓN: En la evolución de las características de la cirugía coronaria (CC) intervienen factores como cambios demográficos, técnica quirúrgica y cuidados perioperatorios. Nuestro objetivo es analizar la evolución de las características de la enfermedad coronaria en pacientes tratados con CC y sus resultados inmediatos. MATERIAL Y MÉTODO: Estudio analítico. Cohorte de pacientes operados con CC aisladas entre enero de 2006 y diciembre de 2008, y entre enero de 2016 y diciembre de 2018 en Hospital Clínico Regional de Concepción, Chile. Revisión bases datos y protocolos quirúrgicos, previa autorización comité de ética. Se utilizó SPSSv25® y pruebas estadísticas Chi-cuadrado y U Mann-Whitney, considerando significativo p < 0,05. Resultados: Total 1.400 CC aisladas, 658 primer período y 742 segundo período. Edad promedio: 62,0 ± 8,7 y 64,6 + 9,3 años según períodos (p < 0,001). Aumentaron significativamente en el segundo período: diabetes mellitus, enfermedad pulmonar obstructiva crónica, infarto agudo al miocardio (IAM), disfunción ventricular grave dentro de subgrupo con disfunción ventricular. Disminución significativa de la cirugía sin circulación extracorpórea, y aumento significativo del uso ≥ 2 puentes arteriales en el segundo período. EuroSCORE I aditivo aumentó de 3,6 ± 2,5 a 4,4 ± 2,7 (p = 0,001). Subgrupo de alto riesgo: 137 (20,8%) a 236 (31,8%), p < 0,001. Mortalidad de 13 (1,98%) y 16 (2,2%) según períodos, p = 0,813. DISCUSIÓN: Se observó aumento significativo del riesgo operatorio estimado, sin embargo, la mortalidad se mantuvo sin variación. El aumento del riesgo operatorio se condice con el aumento de la edad promedio y de la prevalencia de comorbilidades, así como del aumento de disfunción ventricular grave dentro del grupo de pacientes con disfunción ventricular e IAM reciente en el segundo período.
INTRODUCTION: Several factors intervene in the evolution of the characteristics of Coronary artery bypass grafting (CABG), such as demographic changes, surgical technique, and perioperative care. Our objective was to analyze the evolution of the characteristics of coronary artery disease in patients treated with CABG and its immediate results. METHODS: In an analytical study, we analyzed a cohort of patients with isolated CABG from January 2006 to December 2008 and from January 2016 to December 2018 in Hospital Clínico Regional Concepción, Chile. After the ethics committee's approval, we reviewed the database and surgical protocols. We used Chi-square and U Mann Whitney tests for statistical analysis (SPSSv25®), considering significant p < 0,05. RESULTS: We analyzed 1,400 isolated CABG, 658 from the first period and 742 from the second, with a mean age of 62.0 ± 8.7 and 64.6 ± 9.3 respectively (p < 0.001). The subgroup with ventricular dysfunction in the second period showed a significant increase in diabetes mellitus, chronic obstructive pulmonary disease, acute myocardial infarction (AMI), and severe ventricular dysfunction. The second group decreased off-pump surgery and increased the use of ≥ 2 arterial grafts (p < 0.05). The Additive EuroSCORE I increased from 3.6 ± 2.5 to 4.4 ± 2.7 (p = 0.001). High-risk subgroup: 137 (20.8%) to 236 (31.8%), p < 0.001. Mortality of 13 (1.98%) and 16 (2.2%) in the first and second group respectively, p = 0.813. CONCLUSION: There was a significant increase in the estimated surgical risk; however, mortality remained unchanged. The increase in surgical risk is consistent with the increase in mean age and prevalence of comorbidities, as well as the increase in severe ventricular dysfunction in the group ofpatients with ventricular dysfunction and recent AMI in the second period.

BACKGROUND: Dual antiplatelet therapy is recommended for patients with acute coronary syndromes (ACS). Approximately 10% to 15% of these patients will undergo coronary artery bypass graft (CABG) surgery for index events, and current guidelines recommend stopping clopidogrel at least 5 days before CABG. This waiting time has clinical and economic implications. OBJECTIVES: This study aimed to evaluate if a platelet reactivity-based strategy is noninferior to standard of care for 24-h post-CABG bleeding. METHODS: In this randomized, open label noninferiority trial, 190 patients admitted with ACS with indications for CABG and on aspirin and P2Y12 receptor inhibitors, were assigned to either control group, P2Y12 receptor inhibitor withdrawn 5 to 7 days before CABG, or intervention group, daily measurements of platelet reactivity by Multiplate analyzer (Roche Diagnostics GmbH, Vienna, Austria) with CABG planned the next working day after platelet reactivity normalization (pre-defined as ≥46 aggregation units). RESULTS: Within the first 24 h of CABG, the median chest tube drainage was 350 ml (interquartile range [IQR]: 250 to 475 ml) and 350 ml (IQR: 255 to 500 ml) in the intervention and control groups, respectively (p for noninferiority <0.001). The median waiting period between the decision to undergo CABG and the procedure was 112 h (IQR: 66 to 142 h) and 136 h (IQR: 112 to 161 h) (p < 0.001), respectively. In the intention-to-treat analysis, a 6.4% decrease in the median in-hospital expenses was observed in the intervention group (p = 0.014), with 11.2% decrease in the analysis per protocol (p = 0.003). CONCLUSIONS: A strategy based on platelet reactivity-guided is noninferior to the standard of care in patients with ACS awaiting CABG regarding peri-operative bleeding, significantly shortens the waiting time to CABG, and decreases hospital expenses.

BACKGROUND AND AIM: Access to specialized cardiac surgery is a problem in emerging countries. Here, we reflect on the approach we used to establish a cardiac surgery unit in Trinidad and Tobago. METHODS: The program started in 1993 with monthly visits by a team from Bristol Heart Institute. A group of local doctors, nurses, and perfusionists were identified for training, and a senior nurse moved to the island to start a teaching program. The visiting support was gradually reduced, and the local team gained independence in managing the service in 2006. RESULTS: The initial low volume surgery increased to around 380 cases a year with the implementation of comprehensive service in 2006. Most patients required coronary artery bypass graft (CABG). In-hospital mortality declined from 5% in the nascent years to below 2% thereafter. In the last 5 years (2015-2019), 1764 patients underwent surgery (mean age 59.6 ± 10.8 years, 66% male). The majority were East-Indian-Caribbean (79.1%) or Afro-Caribbean (16.7%), half had diabetes, and two-thirds hypertension (EuroScore II 1.8 ± 1.9). The majority (1363 patients) underwent CABG (99.5% off-pump; conversion to on-pump 1.5%). The mean number of grafts was 2.5 ± 0.7 with 98.5% and 23.1% receiving one and two or more arterial grafts, respectively. In-hospital mortality was 1.1%, re-exploration for bleeding 2%, stroke 0.1%, mediastinitis 0.2%. The length of the postoperative hospital stay was 5.8 ± 2 days. CONCLUSION: Frequent outside visits complemented by training in an overseas center, and transfer of knowledge proved to be an effective strategy to develop a cardiac surgery unit in an emerging country with results comparable to accepted international standards.

Abstract Introduction: Coronary artery bypass grafting (CABG) is the most frequently performed heart surgery in Brazil. Recent international guidelines recommend that national societies establish a database on the practice and results of CABG. In anticipation of the recommendation, the BYPASS Registry was introduced in 2015. Objective: To analyze the profile, risk factors and outcomes of patients undergoing CABG in Brazil, as well as to examine the predominant surgical strategy, based on the data included in the BYPASS Registry. Methods: A cross-sectional study of 2292 patients undergoing CABG surgery and cataloged in the BYPASS Registry up to November 2018. Demographic data, clinical presentation, operative variables, and postoperative hospital outcomes were analyzed. Results: Patients referred to CABG in Brazil are predominantly male (71%), with prior myocardial infarction in 41.1% of cases, diabetes in 42.5%, and ejection fraction lower than 40% in 9.7%. The Heart Team indicated surgery in 32.9% of the cases. Most of the patients underwent cardiopulmonary bypass (87%), and cardioplegia was the strategy of myocardial protection chosen in 95.2% of the cases. The left internal thoracic artery was used as a graft in 91% of the cases; the right internal thoracic artery, in 5.6%; and the radial artery in 1.1%. The saphenous vein graft was used in 84.1% of the patients, being the only graft employed in 7.7% of the patients. The median number of coronary vessels treated was 3. Operative mortality was 2.8%, and the incidence of cerebrovascular accident was 1.2%. Conclusion: CABG data in Brazil provided by the BYPASS Registry analysis are representative of our national reality and practice. This database constitutes an important reference for indications and comparisons of therapeutic procedures, as well as to propose subsequent models to improve patient safety and the quality of surgical practice in the country.

OBJECTIVE: The diabetic population has a high prevalence of coronary artery disease, and frequently patients with diabetes undergo coronary artery bypass graft (CABG) surgery. Elevated glycated hemoglobin (HbA1c) in diabetics is shown to be associated with morbidity and mortality, but the association of HbA1c with postoperative length of hospital stay (LOS) has conflicting results. In this study, we aim to identify if elevated HbA1c levels are associated with prolonged LOS after CABG surgery. METHODS: A retrospective chart review study was performed, using a total of 305 patients who were referred for CABG surgery. HbA1c levels were measured before the day of surgery. Patients were classified into two groups according to HbA1c levels: <7% and ≥7%. A LOS of more than 14 days was proposed as an extended LOS. HbA1c and the LOS relationship were assessed using appropriate statistical methods. RESULTS: Patients who had diabetes mellitus comprised 81.6% of our studied population. Sixty-four percent had HbA1c levels ≥ 7%. There was no significant difference in the total LOS in HbA1c <7% compared to HbA1c ≥7% patients (P=0.367). CONCLUSION: Our study results rejected the proposed hypothesis that elevated HbA1c levels ≥7% would be associated with prolonged hospital stay following CABG surgery in a Saudi population.

INTRODUCTION: Smoking is a serious public health issue, being a precursor of heart disease and a predictor of sudden death due to myocardial ischemia. Major events in the patient's health can lead to radical changes in habits and the choice for different myocardial revascularization methods might differently impact smoking cessation and relapse. OBJECTIVE: To study the rate and perpetuation of smoking cessation after myocardial revascularization comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI). METHODS: Smokers submitted to myocardial revascularization were divided into CABG and PCI groups. The research was conducted through interviews at the Hospital Santa Lucinda outpatient clinic. Patients with smoking cessation longer than 90 days before hospital admission, combined procedures, hospital readmission before 360 days after discharge, cases of death at any time, and emergency procedures were excluded from the study. The start of the smoking cessation period was determined as just after hospital discharge, with a follow-up of 12 months. RESULTS: The proportion of patients reporting smoking relapse was significantly lower in the CABG than in the PCI group at 30 (11.1% vs. 20.8%; P=0.039) and at 180 days (23.1% vs. 41.5%; P=0.002), but no differences were observed between the two groups at 360 days after hospital discharge (51.9% vs. 54.1%; P=0.719). High levels of nicotine dependence and passive smoking showed to be important predictors of smoking relapse in the long-term. CONCLUSION: The occurrence of a major surgical procedure seems to have beneficial psychological effects, representing an interesting setting for smoking cessation counseling to have higher chances of success.

INTRODUCTION: Cost management has been identified as an essential tool for the general control and evaluation of health organizations. OBJECTIVES: To identify the coverage percentage of transferred funds from the Unified Health System for coronary artery bypass grafts in a philanthropic hospital having a consolidated costing system in the municipality of São Paulo. METHODS: A quantitative, descriptive and cross-sectional research with information provided from a database composed of 1913 patients undergoing coronary artery bypass graft from March 13 to September 30, 2012, including isolated elective coronary artery bypass graft with the use of extracorporeal circulation. It excluded 551 (28.8%) patients, among them 76 (4.0%) deaths and 8 hospitalized patients, since the cost was compared according to the length of hospital stay. Therefore, the sample consisted of 1362 patients. RESULTS: The average total cost per patient was $7,992.55. The average fund transfer by the Unified Health System was $3,450.73 (48.66%), resulting in a deficit of $4,541.82 (51.34%). CONCLUSION: The Unified Health System transfers covered 48.66% of the average total cost of hospitalization. Although the amount transferred increased with increasing costs, it was not proportional to the total cost, resulting in a percentage difference in revenue that was increasingly negative for each increase in cost and hospital stay. Those hospitalized for longer than seven days presented higher costs, older age, higher percentage of diabetics and chronic kidney disease patients and more postoperative complications.

Abstract Introduction: Smoking is a serious public health issue, being a precursor of heart disease and a predictor of sudden death due to myocardial ischemia. Major events in the patient's health can lead to radical changes in habits and the choice for different myocardial revascularization methods might differently impact smoking cessation and relapse. Objective: To study the rate and perpetuation of smoking cessation after myocardial revascularization comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI). Methods: Smokers submitted to myocardial revascularization were divided into CABG and PCI groups. The research was conducted through interviews at the Hospital Santa Lucinda outpatient clinic. Patients with smoking cessation longer than 90 days before hospital admission, combined procedures, hospital readmission before 360 days after discharge, cases of death at any time, and emergency procedures were excluded from the study. The start of the smoking cessation period was determined as just after hospital discharge, with a follow-up of 12 months. Results: The proportion of patients reporting smoking relapse was significantly lower in the CABG than in the PCI group at 30 (11.1% vs. 20.8%; P=0.039) and at 180 days (23.1% vs. 41.5%; P=0.002), but no differences were observed between the two groups at 360 days after hospital discharge (51.9% vs. 54.1%; P=0.719). High levels of nicotine dependence and passive smoking showed to be important predictors of smoking relapse in the long-term. Conclusion: The occurrence of a major surgical procedure seems to have beneficial psychological effects, representing an interesting setting for smoking cessation counseling to have higher chances of success.

This study aimed to evaluate the efficacy and safety of continuing versus stopping aspirin [acetylsalicylic acid (ASA)] preoperatively in patients undergoing coronary artery bypass graft surgery. MEDLINE, EMBASE, CENTRAL/Cochrane Controlled Trials Register (CCTR), ClinicalTrials.gov, Scientific Electronic Library Online (SciELO), Literatura Latino Americana em Ciências da Saúde (LILACS), Google Scholar and reference lists of relevant articles were searched for randomized controlled trials that reported efficacy outcomes of myocardial infarction and mortality, and safety outcomes of blood loss, packed red blood cell transfusion and surgical re-exploration were compared between groups. Fourteen studies fulfilled our eligibility criteria and included a total of 4499 patients (2329 for 'continuing ASA' and 2170 for 'stopping ASA'). In the pooled analysis, continuing aspirin therapy did not reduce the risk of myocardial infarction [risk ratio 0.834, 95% confidence interval (CI) 0.688-1.010; P = 0.063] or operative mortality (risk ratio 1.384, 95% CI 0.727-2.636; P = 0.323). Preoperative ASA increased postoperative chest tube drainage (mean difference 143 ml, 95% CI 39-248 ml; P = 0.007) and packed red blood cell transfusion (mean difference 142 ml, 95% CI 55-228; P = 0.001) but did not increase the risk of surgical re-exploration (risk ratio 1.316, 95% CI 0.910-1.905; P = 0.145). This meta-analysis found no statistically significant difference regarding the risk of operative mortality and myocardial infarction between the 'continuing ASA' and 'stopping ASA' strategies. On the other hand, the mean volume of blood loss and packed red blood cell transfusion was higher in the 'continuing ASA' group, but this finding did not translate into higher risk of reoperation for bleeding.

BACKGROUND: Little is known about facility-level variation in the use of revascularization procedures for the management of stable obstructive coronary artery disease. Furthermore, it is unknown if variation in the use of coronary revascularization is associated with use of other cardiovascular procedures. METHODS AND RESULTS: We evaluated all elective coronary angiograms performed in the Veterans Affairs system between September 1, 2007, and December 31, 2011, using the Clinical Assessment and Reporting Tool and identified patients with obstructive coronary artery disease. Patients were considered managed with revascularization if they received percutaneous coronary intervention (PCI) or coronary artery bypass grafting within 30 days of diagnosis. We calculated risk-adjusted facility-level rates of overall revascularization, PCI, and coronary artery bypass grafting. In addition, we determined the association between facility-level rates of revascularization and post-PCI stress testing. Among 15 650 patients at 51 Veterans Affairs sites who met inclusion criteria, the median rate of revascularization was 59.6% (interquartile range, 55.7%-66.7%). Across all facilities, risk-adjusted rates of overall revascularization varied from 41.5% to 88.1%, rate of PCI varied from 23.2% to 80.6%, and rate of coronary artery bypass graftingvariedfrom 7.5% to 36.5%. Of 6179 patients who underwent elective PCI, the median rate of stress testing in the 2 years after PCI was 33.7% (interquartile range, 30.7%-47.1%). There was no evidence of correlation between facility-level rate of revascularization and follow-up stress testing. CONCLUSIONS: Within the Veterans Affairs system, we observed large facility-level variation in rates of revascularization for obstructive coronary artery disease, with variation driven primarily by PCI. There was no association between facility-level use of revascularization and follow-up stress testing, suggesting use rates are specific to a particular procedure and not a marker of overall facility-level use.

Objective: To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods: Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results: 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion: This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

AbstractIntroductionAfter removal of endotracheal tube and artificial ventilation, ventilatory support should be continued, offering oxygen supply to ensure an arterial oxygen saturation close to physiological.Objective:The aim of this study was to investigate the effects of positive-end expiratory pressure before extubation on the oxygenation indices of patients undergoing coronary artery bypass grafting.Methods:A randomized clinical trial with seventy-eight patients undergoing coronary artery bypass grafting divided into three groups and ventilated with different positive-end expiratory pressure levels prior to extubation: Group A, 5 cmH2O (n=32); Group B, 8 cmH2O (n=26); and Group C, 10 cmH2O (n=20). Oxygenation index data were obtained from arterial blood gas samples collected at 1, 3, and 6 h after extubation. Patients with chronic pulmonary disease and those who underwent off-pump, emergency, or combined surgeries were excluded. For statistical analysis, we used Shapiro-Wilk, G, Kruskal-Wallis, and analysis of variance tests and set the level of significance at P<0.05.ResultsGroups were homogenous with regard to demographic, clinical, and surgical variables. There were no statistically significant differences between groups in the first 6 h after extubation with regard to oxygenation indices and oxygen therapy utilization.Conclusion:In this sample of patients undergoing coronary artery bypass grafting, the use of different positive-end expiratory pressure levels before extubation did not affect gas exchange or oxygen therapy utilization in the first 6 h after endotracheal tube removal.
ResumoIntrodução:Após a remoção do tubo endotraqueal e ventilação artificial, o suporte ventilatório deve ser continuado, oferecendo suprimento de oxigênio para garantir uma saturação arterial de oxigênio próxima da fisiológica.Objetivo:O objetivo deste estudo foi investigar os efeitos da pressão expiratória positiva final antes de extubação nos índices de oxigenação de pacientes submetidos à cirurgia de revascularização miocárdica.Métodos:Ensaio clínico randomizado com 78 pacientes submetidos à cirurgia de revascularização do miocárdio, divididos em três grupos e ventilados com diferentes níveis de pressão expiratória positiva final antes da extubação: Grupo A, 5 cmH2O (n=32); Grupo B, 8 cm H2O (n=26); e grupo C, 10 cmH2O (n=20). Dados do índice de oxigenação foram obtidos a partir de amostras de gases sanguíneos arteriais coletados em 1, 3 e 6 h após a extubação. Pacientes com doença pulmonar crônica e aqueles que foram submetidos à cirurgia sem circulação extracorpórea, de emergência ou combinadas foram excluídos. Para a análise estatística, foram utilizados Shapiro-Wilk, G, Kruskal-Wallis, e análise dos testes de variância e definição do nível de significância em P<0,05.Resultados:Os grupos foram homogêneos em relação às variáveis demográficas, clínicas e cirúrgicas. Não houve diferenças estatisticamente significativas entre os grupos nas primeiras 6 h após extubação no que diz respeito aos índices de oxigenação e a utilização de oxigenoterapia.Conclusão:Nesta amostra de pacientes submetidos à revascularização do miocárdio, o uso de diferentes níveis de pressão expiratória positiva final antes da extubação não afetou as trocas gasosas ou utilização de oxigenoterapia nas primeiras 6h após a remoção do tubo endotraqueal.
