Risk Factors for Cardiovascular Complications Following Hip Surgery / 대한고관절학회지

ABSTRACT

PURPOSE: This study was performed in order to analyze the incidence of postoperative cardiovascular complications in patients who had undergone hip surgery and to identify risk factors associated with these complications. MATERIALS AND METHODS: A total of 1,390 patients who had undergone hip surgery from 1998 to 2008 were divided into case or control groups according to occurrence of postoperative cardiovascular complications. Both groups were sorted and analyzed by age, gender, mode of operation, bilaterality and history of preoperative cardiovascular disease. Postoperative cardiovascular complication was defined as having any condition including myocardial infarction, congestive heart failure, unstable angina, arrhythmia, hypotension, or pulmonary thromboembolism during the surgical admission period. RESULTS: Forty three out of 1,390 patients(3.1%) experienced cardiovasucular complications and 1 patient (0.07%) died. Increasing patient age (P=0.001), history of bilateral hip surgery (P=0.000), hypertension (P=0.002), coronary artery disease (P=0.000) or valvular heart disease (P=0.010), and ASA category 3 (P=0.000) were all associated with significantly higher incidence of cardiovascular complications. CONCLUSION: Intensive preoperative management though adequate hypertension control and prevention of coronary artery occlusive disease for patients who are elderly or receiving bilateral operation will help decrease the incidence of postoperative cardiovascular complications after hip surgery.
