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.

PURPOSE: Trauma is a leading cause of death, even in previously healthy and disease-free individuals, and the mortality rate is very high in neck trauma patients. On the other hand, there have been few studies related to neck injuries. This study examined the characteristics and treatment results of trauma-related neck injuries using the data from Korean National Emergency Department Information System. METHODS: Neck trauma patients were classified using the 6th Korean Standard Disease Classification system. The patients' demographic factors, number of surgeries, and clinical results were investigated. Statistical analysis was conducted using SPSS to evaluate the annual differences in the demographic factors; mortality according to the site of injury and type of surgery; and mechanisms of injury. RESULTS: From 2011 to 2014, 2,458 neck trauma patients were treated in hospitals in South Korea. The number of patients admitted to regional and local emergency medical centers was 883 (35.9%) and 1,502 (61.1%), respectively. No significant annual differences were observed in age, sex ratio, location of treatment center, mortality, and injury site (vascular, tracheal, or esophageal). In addition, no significant differences in the cause of injury, performed surgery (%), and mortality according to the injured organ were observed. CONCLUSION: This study revealed no annual changes in neck injury patients or differences in mortality according to injured organs. This study can be used as a basis for national research on organ-specific injuries, and may help predict the demand for future support projects for the establishment of regional trauma centers.

OBJECTIVE: To evaluate the effectiveness of cardiac rehabilitation (CR) program on the exercise capacity and secondary prevention in coronary artery obstructive disease (CAOD). METHOD: CR group of 48 CAOD patients had underwent regularly supervised exercise training for 6~8 weeks as well as home exercise continued for 1 year. CR group was advised to control their risk factors by nutrition counsel, abstaining from smoking and reducing their weight. Control group of 16 CAOD patients did not participate in the CR program. Two groups were evaluated for their exercise capacity and risk factors at baseline and after 1 year. RESULTS: CR group showed significantly higher maximal oxygen consumption, maximal rate pressure product and ratings of perceived exertion at stage 3 compared with control group (p<0.05). The number of risk factors per person after 1 year in both groups was significantly lower than baseline (p<0.05), but there was no significant difference between the two groups. CONCLUSION: CR program can improve the exercise capacity and level of risk factor in CAOD patients. Therefore, CR program is recommended for helping CAOD patients improve their functional capacity and reduce the possibility of recurrence.
