The purpose of this paper is to provide an overview of the clinical physical therapy program used at the University of Yonsei Rehabilitation Hospital, for the practicing university trained physical therapists who may be unfamiliar with patients who have suffered a myocardial infarction. The four primary phases of the cardiac physical therapy graded exercise program are: 1) coronary care unit program (phase I), 2) general ward program (phase II), 3) convalescence program (phase III), 4) maintenance program (phase IV). The exercise prescription defines the exercise intensity, duration, frequency, and mode of exercise a after pre- discharge low level graded exercise test(LL-GXT) or symptom limited maximum graded exercise test. A typical exercise routine consists of preparation warm-up exercise, therapeutic exercise, cool-down exercise. Physical therapy is involved in the acute care and rehabilitation of the patient after a myocardial infarction. Therefore, the physical therapist must throughly comprehened the cardiac anatomy, cycle, performance, conduction system, pathogenesis, risk factors, and exercise benefits.

Reperfusion delay in patients with acute myocardial infarction leads to increased morbidity and mortality. We sought to measure the rates of reperfusion delay and to identify factors associated with reperfusion delay after arrival to hospitals. We included 360 patients who had acute myocardial infarction with ST-elevation or left bundle branch block on electrocardiogram and received reperfusion therapy from the three participating academic medical centers from 1997 to 2000. Through retrospective chart review, we collected data about time to reperfusion therapy, patient and hospital factors potentially associated with reperfusion delay. Factors independently associated with reperfusion delay were determined by logistic regression analysis. Median door­to­needle time was 60.0 minutes, and median door­to­balloon time was 102.5 minutes. According to recommendation of the American College of Cardiology/American Heart Association Guidelines, 226 out of 264(85.6％) of thrombolytic patients and 43 out of 96(44.8％) percutaneous transluminal coronary angioplasty(PTCA) patients experienced reperfusion delay. The significant factors associated with delay were type of reperfusion therapy, patient factors including hypertension and delayed symptom onset to presentation(>4 hours), and hospital factors including nocturnal presentation(6pm∼8am), weekend, and an individual hospital. A significant proportion of patients experienced reperfusion delay. The identified predictors of reperfusion delay may help design a hospital system to reduce the delay in reperfusion therapy

The purpose of this study was to investigate the effects of low-intensity cardiac rehabilitation exercise on the cardiac function and the degree of fibrosis in an older white rat model. This study used male Sprague-Dawley white rats that were 50 weeks old. After the acute myocardial infarction induction, Twenty of the rats were randomly allocated into an experimental group and a control group, and each of the groups consisted of 8 rats. In the experimental group, the exercise was conducted for six weeks, 30 minutes a day, five days a week, using a Rotarod treadmill for animals. The degree of myocardial fibrosis was significantly repressed in the experimental group($13.69{\pm}1.90%$) and in the control group($15.67{\pm}1.54%$)(p<0.05). However, fractional shortening and ejection fraction did not show a significant difference. The results of this study suggest that cardiac rehabilitation with low intensity treadmill exercise repress the myocardial fibrosis.

Physical activities in the forest environment stimulate the parasympathetic nervous system of humans and have positive effects on the autonomic nervous system as well as moods and emotions. However, there are almost no studies on the benefits of exercise in the forest environment for patients with myocardial infarction. The aim of this study was to investigate the effects of 15-minute single session walking by myocardial infarction patients in the forest and urban environment on the physiological and psychological states. The heart rate variability was measured in 10 patients with myocardial infarction to assess physiological state after single session walking for 15 minutes in the forest environment and urban environment. In order to evaluate the psychological state, a profile of mood scale (POMS) and semantic differential (SD) questionnaire were used. The results of this study showed that 15-minute single session walking in the forest environment activated the parasympathetic nervous system of adult myocardial infarction patients more than 15 minutes of single session walking in the urban environment, and also made them feel more positive in terms of the POMS and SD. Therefore, this study suggests that even single session walking in the forest environment can positively influence the physiological and psychological states of adult heart disease patients and may also contribute to health care.

The purpose of the study was to investigate effects of Low intensity cardiac rehabilitation, using a treadmill, on the myocardial structure. We identified the effects by analyzing changes in the rats' weights and the results of biopsies. Twenty Sprague-Dawley male rats, 50 weeks old, were randomly divided into the exercise group and the control group. myocardial infarction(MI) was induced by ligaturing their left anterior descending artery. After the acute MI induction, two rats of each group began to fall dead, therefore, eight of each group completed at the end of the experiment. We used treadmills for animals for the exercise group. This exercise group performed 30 minutes of exercise five times per week for six weeks, while the control group did not perform any exercise. No statistically significant differences in weight were found in within group comparison and between group comparison. Furthermore, we observed histological changes in the myocardium using Hematoxylin & Eosin and Masson's trichrome staining in both groups. Low-intensity exercise inhibited myocardial fibrosis, may serve as a reference in the cardiopulmonary field, which plays a role in rehabilitating patients with cardiac disorders, including acute MI.

Purpose: The purpose of this study was to determine whether a relaxing music was effective in reducing stress response of patients admitted to a coronary care unit with the diagnosis of acute myocardial infarction. Method: The research design was the chosen convenience sample of a randomized control group pre-posttest quasi-experimental design. Forty patients, 20 for an experimental group and another 20 for control group. The study was to provide the patients three different kinds of relaxing music. The experimental group listened to relaxing music for a 20-minute one time a day for 3days. The control group was just provided with a 20-minute period of rest. Test for hypothesis was done by repeated measured ANOV A. Result: The experimental group which received relaxing music showed a significantly lower level of electrodermal response, myocardial oxygen consumption and respiration rate, and a higher level of peripheral skin temperature than the control group. The experimental group which received relaxing music showed a significant reduction in state anxiety than the control group. Conclusion: The results showed that relaxing music is an effective nursing intervention for reducing physiologic and psychologic stress response of the patients with acute myocardial infarction in a critical intensive care unit.
