Risk Factors Of Perioperative Cardiovascular Complications In Patients Undergoing Noncardiac Surgery

[Objective] To investigate the incidence and risk factors of perioperative cardiovascular complications in patients undergoing noncardiac surgery.[Methods] From March 2007 to November 2009, we collected the clinical data of 1609 patients over 40 years undergoing elective noncardiac surgery, using a standard table to record the relative date of preoperative, intraoperative and postoperative and followed up the occurrence of cardiovascular complications before discharge of hospital, adopting a statistical method of multivariate Logistic regression analysis to gain the perioperative risk factors of all patients during hospitalization.[Results]â‘ .There were 124 patients experiencing cardiovascular complications, the incidence rate was 7.7%, in which the incidence rate of myocardial ischemia, cardiac arrhythmias, myocardial infarction, cardiac death rates was 3.9%,3.3%,0.2%, 0.34%.â‘¡.The Logistic regression analysis showed:age, ACC/AHA clinical risk factors, metabolic equivalent levels(METs)<4, preoperative history of angina, history of cerebrovascular disease were the independent risk factors of perioperative myocardial ischemia (OR1.060,2.936,34.266,11.703,11.082); age and epidural anesthesia were the independent risk factors of perioperative arrhythmia (OR1.068, 0.436); preoperative myocardial infarction was an independent risk factor of perioperative myocardial infarction (OR18.191); preoperative myocardial infarction and angina pectoris were the independent risk factors of perioperative cardiac death (OR34.520,38.417).[Conclusion]â‘ . The incidence rate of perioperative cardiovascular complications in patients undergoing noncardiac surgery is 7.7%, in which the incidence rate of cardiac death is 0.3%.â‘¡. The factors of perioperative myocardial ischemia include age, ACC /AHA clinical risk factors, METs<4, preoperative history of angina, history of cerebrovascular disease; age and epidural anesthesia are the risk factors of perioperative arrhythmia; preoperative myocardial infarction is the risk factor of perioperative myocardial infarction; preoperative myocardial infarction and angina pectoris are the risk factors of perioperative cardiac death.â‘¢.There are many risk factors of perioperative myocardial ischemia, but not necessarily leading to cardiac death.
