Metabolic syndrome is a well-known cardiovascular risk factor closely related to increased insulin resistance. This study assessed the effects of metabolic syndrome on early post-operative mortality and morbidity in 100 coronary artery bypass graft (CABG) patients: 50 patients with and 50 without metabolic syndrome. A total of 17 patients were excluded from the analysis as they did not attend follow-up, leaving 51 males (61.4%) and 32 (38.6%) females of mean +/- SD age 60.02 +/- 9.76 years for analysis. Diabetes, hypertension and a high body mass index were significantly more common in patients with metabolic syndrome. A statistically significant relationship was found between metabolic syndrome and surgical wound infection. Non-significant positive correlations were found between metabolic syndrome and post-operative atrial fibrillation, surgical revision due to haemorrhage, ventricular tachycardia and ventricular fibrillation, and prolonged intubation. In conclusion, metabolic syndrome did not affect mortality, but did increase the risk of postoperative surgical wound infection.
