Clinical features and outcomes in patients with diabetes mellitus undergoing coronary artery bypass graft in a reference center in southern Brazil

Objetivo: Descrever perfil/evolução de pacientes submetidos à cirurgia de revascularização miocárdica (CRM) em centro de referência cardiológico. Métodos: Estudo de coorte; avaliados todos os pacientes submetidos à CRM (janeiro/2004 e fevereiro/2006, n = 717) quanto às características clínicas/laboratoriais antes, durante e após a cirurgia (infecções, tempo de internação, óbitos). Resultados: Os pacientes tinham 61,9 ± 11 anos, 67,1% homens, 29,6% diabéticos. No transoperatório, aqueles com diabetes usaram cateter venoso central por mais tempo (p < 0,001), mas tempo de circulação extra-corpórea, de clampeamento da aorta e cirúrgico foi semelhante versus os sem diabetes. Infecção ocorreu em 19,1% dos pacientes (40,1% vs. 10,3% nos com e sem diabetes, p < 0,001). Tempo de permanência no hospital foi maior nos pacientes com diabetes versus pacientes sem diabetes, mas não houve diferença no número de óbitos ocorridos entre os grupos (p = 0,797). Conclusão: Pacientes com diabetes submetidos a CRM desenvolvem mais infecções e permanecem mais tempo internados do que aqueles sem diabetes.Objective: To describe clinical/laboratory features of patients undergoing coronary artery bypass graft (CABG) in a cardiology reference center. Methods: Cohort study; data from patients undergoing CABG (January 2004 to February 2006, n = 717) were evaluated for clinical/laboratory features before, during and after surgery (infections, duration of hospital stay, deaths). Results: Patients were 61.9 ± 11 years old, 67.1% males, 29.6% diabetics. Intraoperatively, diabetics had a central venous catheter placed for a longer period (p < 0.001), but extracorporeal circulation, aortic clamping and total surgery times were similar to those for non-diabetics. Infection occurred in 19.1% of patients (40.1% diabetics vs. 10.3% non-diabetics, p < 0.001). The duration of hospital stay was longer for patients with diabetes vs. non-diabetic patients, but there was no difference in deaths between the two groups (p = 0.797). Conclusion: Patients with diabetes undergoing CABG develop more infectious diseases and stay longer in hospital than non-diabetics
