Purpose: Acute myocardial infarction (AMI) leads to death if the patient does not receive emergency treatment. Thus it is very important to recognize the symptoms in the early stage. The purpose of this study was to identify clusters of symptoms that represent AMI in Koreans. Methods: The study used a retrospective, descriptive design with secondary data analysis. Data were abstracted from 725 medical records of AMI patients admitted from June 1, 2006 to August 15, 2014 at a university hospital. Results: Analysis of the AMI symptoms revealed five symptom clusters; Cluster 1 (n=140): middle chest pain (100%), shortness of breath, and cold sweating, Cluster 2 (n=256): substernal pain (100%), cold sweating, and shortness of breath, Cluster 3 (n=47): substernal pain (95.7%), left arm pain, shortness of breath, cold sweating, left shoulder pain, right arm pain, and the lower neck pain, Cluster 4 (n=212): shortness of breath (28.3%), left chest pain, and upper abdominal pain, and Cluster 5 (n=70): cold sweating (100%), left chest pain, shortness of breath, left shoulder pain, and upper abdominal pain. Length of hospital stay and mortality rate were significantly different according to symptom clusters (F=2.52, p =.040; F=3.62, p =.006, respectively). Conclusion: Symptom clusters of AMI from this study can be used for AMI patients in order to recognize their symptoms at an early stage. The study findings should be considered when developing educational prevention programs for Koreans with AMI.

Purpose: The EDIN scale (${\acute{E}}chelle$ Douleur Inconfort Nouveau-$N{\acute{e}}$, neonatal pain and discomfort scale) and heart rate variability has been used for the evaluation of prolonged pain. The aim of our study was to assess the value of the newborn infant parasympathetic evaluation (NIPE) index and EDIN scale for the evaluation of prolonged pain in preterm infants with chest tube placement due to pneumothorax. Methods: This prospective observational study assessed prolonged pain in preterm infants with a gestational age between 33 and 35 weeks undergoing installation of chest tubes. Prolonged pain was assessed using the EDIN scale and NIPE index. Results: There was a significant correlation between the EDIN scale and NIPE index (r=-0.590, P=0.003). Prolonged pain is significantly more severe in the first 6 hours following chest tube installation (NIPE index: 60 [50-86] vs. 68 [45-89], P<0.002; EDIN score: 8 [7-11] vs. 6 [4-8], P<0.001). Conclusion: Prolonged pain can be accurately assessed with the EDIN scale and NIPE index. However, evaluation with the EDIN scale is time-consuming. The NIPE index can provide instantaneous assessment of prolonged and continuous pain.

The enzyme activities of creatine kinase (CK), its isoenzyme MB (CK-MB) and of lactate dehydrogenase isoenzyme 1 (LD-1) have been used for years in diagnosing patients with chest pain in order to differentiate patients with acute myocardial infarction (AMI) from non-AMI patients. These methods are easy to perform as automated analyses, but they are not specific for cardiac muscle damage. During the early 90's the situation changed. First, creatine kinase ME mass (CK-MB mass) replaced the measurement of CK-MB activity. Subsequently cardiac-specific proteins, troponin T (cTnT) and troponin I (cTnI) appeared and displacing LD-1 analysis. However, troponin concentrations in blood increase only from four to six hours after onset of chest pain. Therefore a rapid marker such as myoglobin, fatty acid binding protein or glycogen phosphorylase BB could be used in early diagnosis of AMI. On the other hand, CK-MB isoforms alone may also be useful in rapid diagnosis of cardiac muscle damage. Myoglobin, CK-MB mass, cTnT and cTnI are nowadays widely used in diagnosing patients with acute chest pain. Myoglobin is not cardiac-specific and therefore requires supplementation with some other analyses such as troponins to support the myoglobin value. Troponins are very highly cardiac-specific. Only the sera of some patients with severe renal failure, which requires hemodialysis, have elevated cTnT and/or cTnI without there being any evidence of cardiac damage. The latest studies have shown that elevated troponin levels in sera of hemodialysis patients point to an increased risk of future cardiac events in a similar manner to the elevated troponin values in sera of patients with unstable angina pectoris. In addition, the bedside tests for cTnT and cTnI alone- or together with myoglobin and CK-ME mass can be used instead of quantitative analyses in the diagnosis of patients with chest pain. These rapid tests are easy to perform and they do not require expensive instrumentation. For the diagnosis of patient with chest pain, routinely myoglobin and CK-ME mass measurements should be performed whenever they are requested (24 h/day) and cTnT or cTnI on admission to the hospital and then 4-6 and 12 hours later and maintained less than 10% in imprecision.

Background: Although a physician may be the nearest to the radiation source during C-arm fluoroscope-guided interventions, the radiographer is also near the fluoroscope. We prospectively investigated the radiation exposure of radiographers relative to their location. Methods: The effective dose (ED) was measured with a digital dosimeter on the radiographers' left chest and the side of the table. We observed the location of the radiographers in each procedure related to the mobile support structure of the fluoroscope (Groups A, M and P). Data about age, height, weight, sex, exposure time, radiation absorbed dose (RAD), and the ED at the radiographer's chest and the side of the table was collected. Results: There were 51 cases for Group A, 116 cases for Group M and 144 cases for Group P. No significant differences were noted in the demographic data such as age, height, weight, and male to female ratio, and exposure time, RAD and ED at the side of the table. Group P had the lowest ED ($0.5{\pm}0.8{\mu}Sv$) of all the groups (Group A, $1.6{\pm}2.3{\mu}Sv$; Group M, $1.3{\pm}1.9{\mu}Sv$; P < 0.001). The ED ratio (ED on the radiographer's chest/ED at the side of the table) of Group A was the highest, and the ED radio of Group P was the lowest of all the groups (Group A, $12.2{\pm}21.5%$; Group M, $5.7{\pm}6.5%$; Group P, $2.5{\pm}6.7%$; P < 0.001). Conclusions: Radiographers can easily reduce their radiation exposure by changing their position. Two steps behind the mobile support structure can effectively decrease the exposure of radiographers by about 80%.

Refractory angina pectoris is defined as angina refractory to optimal medical treatment and standard coronary revascularization procedures. Despite recent therapeutic advances, patients with refractory angina pectoris are not adequately treated. Spinal cord stimulation is a minimally invasive and reversible technique which utilizes electrical neuromodulation by means of an electrode implanted in the epidural space. It has been reported to be an effective and safe treatment for refractory angina pectoris. We report a case of spinal cord stimulation which has effectively relieved chest pain due to coronary artery disease in a 40-year-old man. This is the first report of spinal cord stimulation for treatment of refractory angina pectoris in South Korea.

Post-thoracotomy pain is so severe that lead to postoperative pulmonary complications due to the patient`s inability to cough, deep breathing and chest wall motion. Many authors have been trying to reduce the post-thoracotomy pain, but there is no method of complete satisfaction. In 1990, we reported the result that the cryoanalgesia reduce the immediate postoperative pain significantly. We try to compare the effect of cyroanalgesia with the effect of Bupivacain intercostal nerve block for the post-thoracotomy pain control. Ninety patients, who undergoing thoracotomy in Korea University Medical Center Guro Hospital between the January 1993 and September 1993, were evaluated. The patients were divided into three groups : Group A, control, the patients without pain control procedure [N=30], Group B, the patients with Bupivacain intercostal nerve block [N=30], Group C, the patients with cryoanalgesia [N=30]. Postoperative analgesic effects were evaluated by the scoring system which made arbiturary by author. The results were that the Bupivacain intercostal nerve block markedly reduced the immediate postoperative pain compare with two other groups, the cryoanalgesia reduced the immediate postoperative pain significantly compare with control group, the pain reduction effect of the two groups- cryoanalgesia and Bupivacain intercostal nerve block- were not different at postoperative seventh day, probably due to the action time of Bupivacain and the result that there were no significant complications of the procedures.

Background: Health care services effort to provide alternative cardiac rehabilitation (CR) models to serve patients according to their preferences and needs. So, the present study aimed to assess and compare the effects of hospital-based and hybrid CR programs on chest pain intensity and discomfort in cardiac surgery patients. Methods: In this prospective study, 110 cardiac surgery patients were invited to the CR department of a hospital in the western part of Iran between March and July 2016. Patients were divided into two groups: hospital-based and hybrid CR. The hospital-based program included 26 sessions, and the hybrid program included 10 training sessions and exercise. The Brief Pain Inventory and Pain Discomfort Scale were used as research instrument, and data were analyzed using the paired t-test and ANCOVA. Results: The results indicated that both hospital-based and hybrid CR are effective in reducing the chest pain intensity and discomfort of cardiac surgery patients (P < 0.05). In addition, the comparison of scores before and after treatment using ANCOVA shows that no significant differences were observed between the two programs (P > 0.05). Conclusions: Traditional hospital-based CR delivery is still the first choice for treatment in developing countries. However, hybrid CR is as effective as a hospital-based program in reducing pain components and it includes only 38% of the total cost in comparison to hospital-based delivery. So, we recommend using hybrid CR according with the recommendations of American Heart Association about using CR for the management of angina symptoms.

Mid-ventricular obstruction (MVO) rarely occurs in patients without hypertrophic cardiomyopathy. Increased cardiac contractility may play an important role in causing MVO. We experienced a case of severe chest pain and MVO in a 50-year-old female patient. She had hypertension, diabetes, stroke and peripheral artery disease. Her blood pressure was very high (222/122 mmHg) with severe fluctuation. The transthoracic echocardiography revealed MVO accompanied by hyper-dynamic left ventricular systolic function. We regarded her chest pain and MVO as secondary findings related to other diseases. Coronary angiography and several tests for uncontrolled hypertension were performed, and those evaluations revealed that she had coronary artery disease and hyperthyroidism. We considered that the increase in the myocardial oxygen demand in response to the increase in cardiac contractility and workload associated with hyperthyroidism aggravated her symptoms and MVO. She was treated with methimazole and beta blockers and her symptoms dramatically improved.

One woman, Sixty three years old, suffered from chest pain, abdominal pain, nausea and vomiting for about three months. Although many examinations, brain magnetic resonance imaging(MRI), chest computed tomography(CT), abdominal CT, gastric endoscope, abdominal ultrasonography, and so forth, was performed from every point of view, those were non-significant. At first, I wrongly diagnosed her case as disease of Soumin and gave Soumin Gwakhyangjeongkisan. But she complained of diarrhea and chest discomfort. I re-diagnosed her case as Soyangin Gyeolhyung and treated with Hyeongbangdojeoksan, herbal medicine, consisted of Rhizoma Rehmanniae(生地黃), Lignum Akebiae(木通), Radix Scrophulariae(玄蔘), Semen Trichosanthis(瓜蔞仁), etc. Three weeks have passed from first visit and she did not suffered from pain. I experienced the excellent effect of Hyeongbangdojeoksan to Soyangin Gyeonlhyung.
