title: [Values of computed tomography angiogram in non-cardiac surgery planning and cardiac risk assessment of coronary atherosclerosis during perioperative period].
abstract: OBJECTIVE
  To explore the values of detecting coronary atherosclerosis by computed tomography angiogram (CTA) on non-cardiac surgery planning and cardiac risk assessment of coronary atherosclerosis during perioperative period.
  
  
  METHODS
  A total of 89 patients with suspected coronary heart disease (CHD) scheduled for non-cardiac surgery underwent coronary CTA to evaluate luminal stenosis and calculate calcification score. There were 56 males and 33 females with a mean age of 65.1 years. Operative sites included chests (n = 29), abdomens and pelvis (n = 26), large vessels (n = 3), bones and joints (n = 19) and other regions (n = 12). Reasons of abandoned or postponed surgery were documented to analyze the influence of CTA results on surgery planning. Cardiac events were recorded to assess the correlation with coronary atherosclerosis.
  
  
  RESULTS
  Among them, 75 patients (84.27%) were diagnosed as atherosclerosis while 10 patients (11.24%) were negative; 2 patients had coronary artery bypass and another 2 had stent implantation. According to the results of CTA, 12 operations (13.48%) were canceled and 8 (8.98%) postponed after interventions. Severe stenosis of coronary lumen had significant effects on surgery planning (P = 0.003) while calcification score did not. In patients undergoing surgery as scheduled or after intervention, 1 had atrial fibrillation at post-operation.
  
  
  CONCLUSIONS
  For the patients with suspected CHD scheduled for non-cardiac surgery, severity of coronary stenosis may greatly influence surgery planning. Preoperative coronary CTA may decrease the incidence of cardiac events during perioperative period.
