Purpose:In order to improve the quality of cardiac rehabilitation, it is important to examine the experiences of the patients and how they feel about each part of the process. We used a qualitative research methodology to conduct an in-depth review of the experiences of patients who participated in cardiac rehabilitation. Methods: According to semi-structured guidelines, in-depth interviews were conducted with a total of five patients undergoing cardiac rehabilitation. Results: A total of 232 codes was derived; these codes were split into 4 categories and 10 subcategories. Although the patients were apprehensive about the diagnosis of heart disease, it also gave them a chance to reflect on their health behaviors of the past. In addition, they began to appreciate their families and support networks more as the disease progressed. The participants did not know about cardiac rehabilitation until the medical staff recommended it, but they participated in the program with the expectation that they could become healthier. The participants felt that they became more physically and mentally healthy while undergoing cardiac rehabilitation. Rehabilitation served as an opportunity to improve other health behaviors as well. However, they emphasized that it is necessary to continuously maintain improved health behavior, find an exercise method that is suitable for one's physical ability and not monotonous, and prepare a plan to reduce the time and economic burden of cardiac rehabilitation. Conclusion: The participants' positive experiences confirmed in this study will be used as evidence for the expansion of cardiac rehabilitation programs.

Purpose: The purpose of this study was to investigate the effects of an individualized cardiac health education on self-care behavior and serum cholesterol levels patients with coronary artery disease. Methods: Twenty-two patients in the intervention group and 22 in the control group were assigned randomly in this study. The intervention group received an individualized cardiac health education program which consisted of four different sessions for a total of four sessions. Specifically, two sessions occurred during the patients' hospitalization with a third session at the time of discharge with a fourth session scheduled via telephone one week post discharge. Data were collected through a questionnaire for self-care behavior and a blood test for total cholesterol at the time of admission and the two weeks after discharge. The questionnaire for self-care behavior was a standardized instrument and serum cholesterol was measured by Accutrend GC (Roche, Germany). Results: Self-care behavior scores included diet, medication, exercise, risk factor, blood pressure measurement, and visits to hospital were significantly more in the experimental group compared to the control group. Conclusion: The above findings indicate that the individualized cardiac health education was effective in increasing of self-care behavior.

Gated blood pool scan is frequently used for evaluating the change in cardiac function in various cardiac diseases. But resting gated blood pool scan using only LVEF as a cardiac index has been consitently shown to have a low sensitivity, which is about 50%, in detecting coronary artery disease. So it is recommended to compare exercise gated blood pool scan to resting gated blood pool scan. Exercise tests, however, are not always possible, especially in patients with musculoskeletal diseases, recent myocardial infarction and in elderly persons. We studied the usefulness of resting gated blood pool scan using multiple indices in evaluating the patients with coronary artery disease. Studied cases were 185 patients with coronary artery disease (angina pectoris 31, myocardial infarction 154) and 25 normals with low likelihood of coronary artery disease. We used $^{99m}Tc-labeled$ RBC, 740 MBq labeled by in vivo method. The data were evaluated by Micro DELTA computer program. The results were as following: 1) The ejection rates (PER, AER) and filling rates (PFR, AFR) were different in normls and patients with angina pectoris or myocardial infarction. 2) Mean phase angle, ejection rates and filling rates could separate normals from coronary artery disease patients with normal LVEF. 3) Regional ejection fraction was decreased at the site of the infarct in patients with myocardial infarction. 4) Peak filling rate was the the most detectable index in evaluation of cardiac function in patients with coronary artery disease. 5) The threshold at 1.5 standard deviation of normal range was considered as the most reliable cut-off value from ROC analysis. These data suggest that the resting gated blood pool scan has an important role in the evaluation of cardiac functional changes using various cardiac indices in patients with coronary artery disease.

본 연구는 중년 남성들을 대상으로 3년간 1년에 1회씩 3차례에 걸쳐 운동부하 검사 시 심전도 반응을 측정하여 야외 및 트레드밀 걷기 운동 참여 여부에 따라 부하 심전도의 변화에 어떠한 양상이 나타나는지를 규명하고자, 안정 시 신체조성 분석, 운동부하 검사 시 심전도 반응을 측정하였다. 안정 시 신체조성 분석은 체지방율과 BMI를 측정하였고, 안정 시 및 운동부하 검사 시 심전도 반응은 ST/HR 경사 및 QRS 벡터를 측정하였는데, 그 결과는 다음과 같다. 1. ST/HR 경사의 변화에 있어서 운동 6분부터 통제 집단은 감소하기 시작하여 운동 9분과 peak시에 $2.4\;{\mu}V/bpm$ 이하로 감소하여 허혈 증상이 나타났다. 2. QRS 벡터의 축 각도에 있어서 안정 시 전면 축은 시간이 경과함에 따라 통제 집단이 우측으로 유의하게 편향되었고, 안정 시 수평면 축은 시간이 경과함에 따라 통제 집단이 등 쪽으로 유의하게 향하였다. 안정 시 수평면 파고의 길이에 있어서 통제 집단은 시간이 경과함에 따라 유의하게 감소하였고 걷기 운동 집단은 유의하게 증가하였다. 결론적으로 비 활동의 중년 남성들은 운동 중 심근 허혈 유발, QRS 벡터의 편향 등이 현저하게 나타난 반면, 규칙적인 야외 및 트레드밀 걷기 활동에 참여한 중년 남성들은 심혈관계 질환 위험 요소의 감소로 심장기능이 향상된 결과를 알 수 있었다.

Purpose: This study was performed to analyse the trends of risk factor management programs for patients with coronary artery disease. Methods: Using PubMed, 35 intervention studies related to risk factor management programs among randomized controlled trials searched with the key words of coronary artery disease and coronary heart disease. Collected studies were analysed according to the characteristics of studies and participants, method and content of intervention, and outcome indicator and its effects. Results: The mean period of intervention was $28.7{\pm}26.8$ weeks, the mean frequency was $3.0{\pm}2.0$ times per week, and the duration of one session was below 60 minuets in 65.8% of the reviewed studies. The interventions were counselling, exercise, education, and cognitive behavior therapy. Counselling was applied most frequently in previous studies. The outcomes of intervention had been measured with anthropometric, physical, physiological, psychological, behavioral, and cognitive aspects, but the effect of the intervention was inconsistent among the studies. Conclusion: Based on the results of this study, systematic and comprehensive cardiac rehabilitation program consisted of counselling, exercise, and education should be developed and performed for health management and relapse prevention of patients with coronary artery disease.

Objective: The purpose of this study was to determine pretreatment effects of moderate-term endurance training before the various dosages (10 and $20{_{mg.kg}}^{-1}$) of DOX on a heat shock protein ($HSP_{70kda}$) and cardiotoxicity in heart tissue. Methods: Forty-eight male rats were randomly assigned to nontraining (NT) and training (T) groups and three subgroups; $DOX{_{10mg.kg}}^{-1}$ and $DOX{_{20mg.kg}}^{-1}$ and saline treatment. The training program included treadmill running between 25-39 min/day and 15-17 m/min, 5 days/wk for 3 wk. Result: DOX administration, in particularly with $20{_{mg.kg}}^{-1}$, caused up-regulation of oxidants and cardiac damage (MDA, CK, CPK-MB and CK/CPK-MB) and down-regulation of cardioprotection ($HSP_{70}$, SOD) markers, as compared to NT+saline group. Pretreatment effect of treadmill running endurance exercise in the presence of DOX with $10{_{mg.kg}}^{-1}$ caused a significant increase in $HSP_{70}$, SOD and a significant decrease in MDA and insignificant decrease in CK, CPK-MB and CK/CPK-MB, in comparison $T+DOX_{10}$ with $NT+DOX_{10}$ group. However, there was no significant difference between $T+DOX{_{10mg.kg}}^{-1}$ and $T+DOX{_{20mg.kg}}^{-1}$ in the aforesaid markers. Conclusion: Dox-induced cardiotoxicity is related to oxidative stress. Our study suggests that pretreatment with endurance exercise may be considered as a potentially useful strategy to improve myocardial tolerance against single dose DOX-induced oxidative damage.

장기간 체중부하운동이 흰쥐의 심근에 미치는 효과를 규명하기 위하여 생후 3개월, 10개월 및 20개월된 흰쥐를 5개월간 운동시킨 후 각각의 비운동군과 비교하여 심근의 조직학적ㆍ세포학적 변화를 관찰하고, 심근세포내 미세구조적 변화를 입체해석학적으로 비교 분석하였다. 운동 15개월군부터 노화색소의 양이 현저히 증가되었고 사립체의 변성, 공포화 현상 그리고 간질조직의 증식이 뚜렷하였으며, 25개월군에서는 윤반분리, 근원섬유의 소실 및 과수축대 출현빈도가 증가되었다. Glucose-6-phosphatase의 활성도는 15개월 운동군에서 감소하여 25개월 운동군에서는 활성도가 거의 나타나지 않았다. 입체해석학적 결과에서도 장기간 체중부하운동으로 인해 15개월, 25개월군에서 모두 사립체와 근원섬유의 체적밀도는 감소되었고, 간질조직의 체적밀도는 증가되었다. 본 연구의 결과로 볼 때 장기간 체중부하운동은 3개월군에 있어서 심장에 미치는 역효과가 없으나 10개월군과 20개월군에서는 심근기능강화에 역효과를 초래 할 우려가 큰 것으로 판단된다.
