To assess the early results, risk factors and optimal timing for coronary artery bypass graft surgery(CABG) after an acute myocardial infarction(AMI), we reviewed our 19 patients who underwent CABG within 30 days after AMI, between June 1994 and October 1996. This study excluded 1 patient whose diagnosis was AMI with ventricular septal rupture. 14 of the patients were male and 5 were female. Their ages ranged from 41 to 77 years(mean age, 60.6$\pm$ 10.4 years), and the amount of time between AMI and CABG ranged from 8 hours to 24 days(mean time, 10.6$\pm$6.4 days). There were 11 anteroseptal infarctions and 8 inferior wall infarctions. 11 patients had trsnsmural infarctions and 8 had subendocardial infarctions. Indications of operations were p imary revascularization and postinfarction angina. Three patients required preoperative intra-aortic balloon pump(IABP) support, and 4 additional patients required IABP to be separated from cardiopulmonary bypass. An average of 3.6 $\pm$ 0.6 vessels per patient were bypassed. The early mortality rate for these 19 patients was 5.3% and late mortality rate was 5.5%, 1-year and 2-year actuarial survival rates were 89.5% Univariate analysis of mortality showed that an ejection fraction less than 30% and intraopretative IABP supports were associated with risk factors(p value=0.018 and 0.015 respectively). Age, sex, time to CABG, emergency operations, types and locations of infarctions were not significant. Although our studies have weak p.oints in that there was only a small number of patients and the lack of long-term results, we could conclude that early myocardial revascularization is relatively safe after AMI for those individuals with an ejection fraction greater than 30%.

This study is analyzed the implementation of medical aid for patients over 65 years of age who are among the discharged from hospitals with the capacity of over 100 beds. I have analyzed it with the data from an in-depth study of injury surveillance of discharged patients from hospitals done in a national project in 2004. After analyzing the results of the data from the beginning of this national project to the data collected in 2008, I could get the results that the rate of discharged patients over 65 years of age increased every year. Among them, the rate of discharged women was higher than that of the men, and the rate of deaths while at the hospital for patients over 65 years of age was higher than that of patients less than 65 years of age. The rate of operations done on patients over 65 was lower than that of patients under 65 years of age. The results of a diagnosis of popular symptoms showed that the rate of the diagnosis of cerebral infraction and structure of the heart at the circulatory organ was higher. In addition, the rate of the diagnosis of lung cancer, pneumonia, and chronic obstructive lung disease was higher, as well as the rates of gastric cancer, diabetes, liver cancer, and colorectal cancer. The results showed that the operation of the nerve system or cardiovascular system were higher. Therefore, according to this result, we should prioritize and allocate resources to the elderly people when setting up a management policy. And also, we should promote healthcare for elderly people after considering the characteristics of the implementation of medical aid in preparation of a super-aged society.

The objective of this study was to make a comparison on anger level between patients with coronary artery diseases and healthy individuals. 233 patients with coronary artery diseases and 215 normal controls were enrolled in this study. The Anger Expression Scale, the anger and aggression subscales of the Stress Response Inventory(SRI) and the hostility subscale of the Symptom Checklist-90-revised(SCL-90-R) were used to assess the level of anger. The patients with coronary artery diseases scored significantly higher on the anger-out and anger total subscales of the anger expression scale, the anger and aggression subscales of the SRI than the normal controls. The patients with angina pectoris had significantly higher scores in the anger-out and anger-total subscale than those with myocardial infarction. Male subjects scored significantly higher on the anger-in subscale than females, whereas female subjects scored significantly higher on the anger-out subscale than male subjects. These results suggest that patients with coronary artery diseases are likely to have a higher level of anger or anger expression than normal controls and that there may be difference in anger expression between male and female patients. It is emphasized that anger management is needed to prevent the coronary artery disease patients from aggravating the illness.

심장의 박동수 자율신경계에 있어서 매우 중요한 감성 지표가 되어 왔다. 정상인 심장박동수의 개인간 차이는 유의하게 다르지 않다. 그러나 심장병 환자는 건강한 사람들과 유의한 차이를 보이게 된다. 특히 허혈 초기에는 증상이 잘 나타나지 않기 때문에 일부러 심장에 부하를 주어서 허혈 유무를 판정하기도 한다. 부하를 주는 방법은 운동에 의한 운동부하검사, 약물에 의한 약물부하검사로 나뉜다. 신체조건 및 안정상 운동부하 검사가 불가능한 경우에는 약물을 이용한다. 심전도를 이용한 심장부하 연구는 많이 수행되어 왔으나 심자도 연구는 초기단계이다. 본 연구에서는 20 대 정상인 20 명과 협심증 환자들 27명에게 약물 부하를 유도하여 나타난 심박수, 심자도의 차이를 비교하였다. 또한 8 명의 정상인을 대상으로 가혹한 운동부하를 일으켜 최대 부하상태에선 안정 상태까지 이르는 과정을 심자도로 관찰하였다. 결과로서 운동부하 검사에서 야기되는 스트레스의 정도는 약물로 얻어지는 부하에 비해 유의하게 큼을 알 수 있었다. 또한 약물 스트레스는 정상인의 심장 전기생리학적 변화는 미미하지만 일부 허혈 환자들에게서는 유의한 차이를 보였다. 미약한 약물 스트레스에 대해 변화되는 정도가 심자도에 관찰되어 허혈 검사에 사용 가능성을 보였다.

In removable partial denture with crossed occlusion, it is difficult to meet the satisfaction of patient due to variable movement of denture and unfavorable stability under loading. In a case with few unilaterally teeth remaining, additional treatments such as implantation or residual root are required to assure bilaterally stable support. However, due to the medical condition of the patient with hypertension, angina and old age etc., removable partial denture was planned as treatment in this case. Proper diagnosis, accurate analysis and full understanding of the adaptation for neuromuscular system are necessary to recover the vertical dimension of patient from a decreased vertical dimension due to crossed occlusion.

Background: Acute myocardial infarction (MI) is a life-threatening disease and surgical revascularization plays a major role in selected cases. The purpose of this study is to evaluate the left ventricular contractility improvement by examining the wall motion score index (WMSI) and left ventricular ejection fraction (LVEF) in patients who under-went surgical revascularization under diagnosis of acute MI. Material and Method: From January, 2001 to December, 2004, 149 patients who underwent coronary artery bypass surgery within 2 weeks of acute MI were included. We evaluated pre- and postoperative left ventricular contractility by measuring WMSI and LVEF and examined the associating factors. Result: WMSI decreased from $1.54{\pm}4.30\;to\;1.43{\pm}0.40$ (p<0.001) and LVEF increased from $48.1{\pm}12.2%\;to\;49.7{\pm}12.3%$ after surgery (p=0.009). Off-pump technique, non-Q wave, anterior MI, and surgery within 7 days after MI were favorable factors for LVEF improvement (p=0.046, p=0.006, p=0.003, p=0.005, respectively). Conversely, aforementioned factors were irrelevant with WMSI improvement. For triple vessel disease, complete revascularization was favorable factor for WMSI improvement (p<0.001). Conclusion: Coronary artery by-pass surgery can improve WMSI and LVEF in patients with acute MI. In case of anterior MI with non-Q wave, early surgical revascularization within 7 days may be most beneficial in LVEF improvement. Regarding WMSI, complete revascularization may be essential.

As the prevalence of coronay artery disease is increasing, the surgical treatment has been universalized and operative outcome has been improved. We analyzed the short and mid-term results of 292 CABGs performed in Kangdong Sacred Heart Hospital. Material and Method: From June 1994 to December 2001, 292 patients underwent coronary artery bypass grafting. There were 173 men and 119 women and their ages ranged from 39 to 84 years with a mean of $61.8{\pm}9.1$ years. We analyzed the preoperative risk factors, operative procedures and operative outcome. In addition, we analyzed the recurrence of symptoms, long-term mortality and complications via out-patient follow-up for discharged patients. Result: Preoperative clinical diagnoses were unstable angina in 137(46.9%), stable angina in 34(11.6%), acute myocardial infarction in 40(13.7%), non-Q myocardial infarction in 25(8.6%), postinfarction angina in 22(7.5%), cardiogenic shock in 30(10.3%) and PTCA failure in 4(1.4%) patients. Preoperative angiographic diagnoses were three-vessel disease in 157(53.8%), two-vessel disease in 35 (12.0%), one-vessel disease in 11(3.8%) and left main disease in 89(30.5%) patients. We used saphenous veins in 630, internal thoracic arteries in 257, radial arteries in 50, and right gastoepiploic arteries in 2 distal anastomoses. The mean number of distal anastomoses per patient was $3.2{\pm}1.0$ There were 18 concomitant procedures ; valve replacement in 8(2.7%), left main coronary artery angioplasty in 6(2.1%), patch closure of postinfarction ventricular septal defect(PMI-VSD) in 2(0.7%), replacement of ascending aorta in 1(0.3%) and coronary endarterectomy in 1(0.3%) patient. The mean ACC time was $96.6{\pm}35.3 $ minutes and the mean CPB time was $179.2{\pm}94.6$ minutes. Total early mortality was 8.6%, but it was 3.1% in elective operations. The most common cause of early mortality was low cardiac output syndrome in 6(2.1%) patients. The stastistically significant risk factors for early mortality were hypertension, old age($\geq$ 70 years), poor LV function(EF＜40%), congestive heart failure, preoperative intraaortic balloon pump, emergency operation and chronic renal failure. The most common complication was arrhythmia in 52(17.8%) patients. The mean follow-up period was $39.0{\pm}27.0$ months. Most patients were free of symptoms during follow-up. Fourteen patients(5.8 %) had recurrent symptoms and 7 patients(2.9%) died during follow-up period. Follow-up coronary angiography was performed in 13 patients with recurrent symptoms and they were managed by surgical and medical treatment according to the coronary angiographic result. Conclusion: The operative and late results of CABG in our hospital, was acceptable. However, There should be more refinement in operative technique and postoperative management to improve the results.

Transabdominal approach in redo coronary artery bypass grafting(CABG) may avoid the risk related to repeat sternotomy. Redo CABG using this approach can be performed safely in selected cases. We report a case of redo off-pump CABG through a transabdominal approach in a 59-year-old woman with recurrent unstable angina after a previous CABG. Through a curvilinear epigastric incision, right gastroepiploic artery(RGEA) was harvested as a graft, and the RGEA-to-right coronary artery anastomosis was performed on the beating heart. A 1-day postoperative angiographic study showed the patent RGEA graft, and she was discharged on postoperative 4th day without any complication.

A 44-year-old male complained of chest pain. Two years ago he was diagnosed with angina pectoris for stenosis of coronary artery in coronary angiography. Despite of medication, his chest pain aggravated to cardiovascular society classification class III. His electrocardiogram, cardiac enzymes were normal. Accordingly we diagnosed him with unstable angina. And we pattern differentiated him with heart heat syndrome considering his other symptoms. He wanted conservative care instead of coronary artery intervention generally recommended for treating unstable angina. We treated him for 13-days with tongxinluo, modified daochi-san, acupuncture, smoking prohibition which were thought to be effective for treating unstable angina based on experimental, clinical studies. Within the therapeutic period, frequency of chest pain and frequency of taking nitroglycerin were on the decrease.

Variant angina causes chest pain due to abnormal coronary vasospasms. A 60-year-old male who was diagnosed with variant angina was admitted to the Oriental Medicine Hospital and treated with herbal medicines, including Pyungjinsujeom-san and Simjeok-hwan. After treatment, the frequency of chest pain and use of nitroglycerin decreased. Subjective symptoms of chest pain measured using a numerical rating scale (NRS) also decreased. These improvements persisted throughout the hospitalization period. In conclusion, Korean medicines, including Pyungjinsujeom-san and Simjeok-hwan, can be effective for patients with chest pain due to variant angina.
