Abstract: 【Abstract】Objective To analyze the perioperative characteristics and risk of elderly patients underwent cardiac surgery. Method From January 2007 to June 2011, 255 patients underwent different cardiac surgery were included in this study. The patients were divided by age into two groups : 55 patients with age ≥70 years in group A and 200 patients with age <70 years in group B. Preoperative risk factors, surgical strategy, perioperative management, postoperative complications and prognosis were compared between the two groups. Result Hypertension, acute coronary syndrome and renal insufficiency were found significantly higher in group A than in group B(P<0.05), and so was EuroSCORE (5.56±2.26 vs 2.14±2.21, P<0.05); Time of cardiopulmonary bypass in group A (102.61±38.36min) was significantly shorter than in Group B (119.66±47.57min , P<0.05), and so was time of aorta cross clamping (63.57±27.08min vs 79.46±35.29min , P<0.05 ). Frequency of postoperative lung infection and acute kidney injury in group A were significantly higher than in Group B( P<0.05). Ventilation time and length of ICU stay were significantly longer in group A than in group B. There was no significant difference in stroke, severe ventricular arrhythmia, total drainage, use of inotropic drugs between the two groups. No significantly difference in hospital mortality was shown between the two groups. Conclusion: Careful discrimination of perioperative risks, individualized surgical strategy, shorter cardiopulmonary bypass time ,active and correct management of postoperative complications may reduce operative risk and mortality for elderly patients in cardiac surgery.
