Purpose: The purpose of this study was to determine the differences in the level of disease related knowledge, compliance of health behavior, and educational needs in relation to time (at discharge and 6 months after discharge) among patients underwent percutaneous coronary intervention (PCI). Methods: Data were collected from January 1, 2006 to September 30, 2006 and a total of 60 patients participated in the study. The survey was conducted in patients underwent PCI at the time of discharge right after discharge education was provided and at a follow up visit which was 6 months after discharge. Results: The level of disease related knowledge (p<.001), the compliance of health behavior (p<.001), educational need (p=.496), the sub-item of sexual life (p<.001), follow up (p<.001), diet (p=.021), stress (p<.001) in compliance of health behavior, and the sub-item of specific character of disease in educational needs (p=.015) were significantly different between discharge and 6 months after discharge. Conclusion: The results of this study suggested that further education should be provided to the patients underwent PCI regarding medication, smoking cessation, daily life and exercise at a time of 6 months after discharge in order to increase patient compliance of health behavior.

This study was conducted to determine whether level-1 emergency medical technicians (EMTs) can adequately recognize ST-segment elevation myocardial infarction (STEMI) in the emergency department (ED) and whether their ability to do so differs from that of emergency medicine physicians (EMP). From December 2022 to November 2023, patients aged 20 years or older visiting the ED with chief complaints suggesting acute coronary syndrome (ACS) were enrolled. As soon as the patient arrived at the ED, a level-1 EMT conducted a 12-lead electrocardiogram (ECG) to assess STEMI; an EMP subsequently assessed whether to activate the percutaneous coronary intervention team. Demographic characteristics, test results, and final diagnoses were collected from the medical records. Among the 723 patients with case report forms, 720 were included in the analysis. These were categorized as follows: 117 (16.3%) with STEMI, 159 (22.1%) with non-ST-segment elevation ACS, and 444 (61.7%) with other conditions. STEMI was correctly recognized in 100 patients (91.7%) by level-1 EMTs and in 104 patients (95.4%) by EMPs (kappa=0.646). EMTs with less than 1 year of ED work experience correctly recognized 60 out of 67 STEMI patients (89.6%), which was comparable with the EMPs who recognized 65 out of 67 STEMI patients (97.0%, kappa=0.614). EMTs with more than 1 year of ED work correctly recognized 40 out of 42 STEMI patients (95.2%), and therefore performed better than EMPs, who recognized 39 out of 42 STEMI patients (92.9%, kappa=0.727). The level-1 EMTs adequately recognized STEMI using a 12-lead ECG and were in substantial agreement with the evaluations of the EMPs.

Coronary artery disease (CAD) has been increasing during the last decade and is the one of major causes of death. The management of patients with coronary artery disease has evolved considerably. There are two main strategies in the management of CAD, complementary, not competitive, each other; the pharmacologic therapy to prevent and treat CAD and the percutaneous coronary Intervention (PCI) to restore coronary flow. Antiplatelet drugs and cholesterol lowering drugs have central roles in pharmacotherapy. Drug eluting stent (DES) bring about revolutional changes in PCI. In the management of patients with 57 segment elevation acute myocardial infarction (AMI), there has been a debate on the better strategy for the restoration of coronary flow. Thrombolytic therapy is widely available and easy to administer, whereas primary PCI is less available and more complex, but mote complete. Recently published evidences in the pharmacologic therapy including antiplatelet and stalin, and PCI including DES and reperfusion therapy in patients with ST segment elevation AMI were reviewed.

최근 순환기계 질환이 증가함에 따라 경피적 관상동맥 중재술이 관상동맥 치료에 주된 치료 방법으로 사용되고 있다. 이러한 이유로 방사선을 이용하는 중재술이 증가함에 따라 작업종사자의 방사선피폭을 증가되고 그에 따른 잠재적 방사선 장해를 증가 시킬 수가 있을 것이다. 이에 본 연구에서는 방사선 차폐체인 납 커튼 유 무에 따른 슬 하부 주변 선량을 측정하였다. 실험방법은 자동노출조건 60kV, 200mA, 10mS 을 이용하여 본원에 주로 사용되는 관상동맥 촬영방법을 이용하여 슬 하부 주변부 선량을 측정하였다. 결과로는 right coronary artery 검사 시, LAO $30^{\circ}$을 경우 납 커튼사용 유 무에 따른 방서선 방어효과는 98.4%, $Cranial30^{\circ}$ 98.3% 효과를 가진다. left circumflex coronary artery 검사 시, Caudal $30^{\circ}$을 경우 납 커튼 사용 유 무에 따른 방사선 방어효과는 90.2%, Caudal $30^{\circ}$ LAO $30^{\circ}$ 88.7%의 효과를 가진다. left anterior descending artery 검사 시, $Cranial30^{\circ}$을 경우 납 커튼 사용 유 무에 따른 방사선 방어효과는 98.3%, Cranial $30^{\circ}RAO$ $30^{\circ}$ 80.3%, Cranial $30^{\circ}LAO$ $30^{\circ}$ 98%의 효과를 가진다. OS(Spider view) 검사 시, Caudal $40^{\circ}$ LAO $40^{\circ}$을 경우 납 커튼 사용 유 무에 따른 방사선 방어효과는 71.2%의 효과를 가지는 것으로 나타났다. 이러한 이유로 방사선 작업종사자의 경우 방사선 차폐 보조기구를 사용을 불편하더라도 가능한 방사선 차폐도구를 이용함으로써 자신의 방사선 피폭관리에 관심을 기울려야 할 것이다.

관상동맥 중재술은 관상동맥 조영술과 동시에 치료를 시행하는 방법으로 심도관 검사의 핵심으로 자리잡았다. 관상동맥중재술 시에는 혈관의 협착지점에 스텐트를 삽입하여야 하기 때문에 혈관의 손상이나 파열에 주의하여야 한다. 이에 시술자는 혈관의 손상이나 파열의 문제를 해결하기 위해 혈관의 경로를 정확하게 인식하여야 한다. 하지만 영상의 화질에 따른 문제들로 인하여 혈관의 경로추출에 오류를 범할 수 있다. 따라서 본 논문에서는 영상의 화질에 영향을 미치는 영상잡음에 대한 성능평가를 위하여 전처리 과정으로 미디언 필터링을 실시하였고 비교 실험을 위해 소벨 에지 추출 기법을 이용하여 퍼지 에지 추출 기법의 성능을 실험하였다. 그 결과 미디언 필터링을 적용한 퍼지 에지추출 기법의 영상이 잡음 제거와 신호의 검출 성능이 우수하게 나타났다.

의료급여수급권자는 낮은 본인부담으로 인해 공급자에 의한 유발의료수요가 발생하거나 수급권자의 도덕적 해이가 발생하여, 의료서비스 남용으로 인한 의료급여 재정의 건전성을 저해한다는 지적을 받고 있다. 이 연구는 관상동맥중재술과 같은 질병부담이 높은 의료서비스 이용에 있어서 우리나라의 대표적인 의료보장형태인 건강보험환자와 의료급여환자의 진료비 발생 구조를 분석하여 진료비 관리의 정책적 방향을 제시하고자 수행되었다. 관상동맥중재술 시행을 받은 환자에서 의료보장형태에 따라 의료서비스 이용 양상 및 진료비 구조에 차이가 있었다. 의료급여군이 건강보험군에 비해 재원일수가 길고, 응급실을 경유하여 입원한 환자의 비율이 높았으며, 비급여진료비, 선택진료비, 일당 비급여진료비가 적게 발생하였고, 재원일수와 관련 있는 진찰료 및 입원료, 식대, 투약 및 주사료 항목에서는 총 진료비가 많이 발생하였다. 따라서, 국가차원의 효율적인 진료비 관리를 위해서 취약계층에 대한 예방과 교육서비스를 제공하여 사전적 진료비관리가 이루어져야 하며, 의료급여 환자의 재원일수 증가에 따른 급여진료비 발생을 관리하는 전략이 필요할 것으로 보인다. 또한, 비급여 진료비에 있어서 의료급여환자의 미충족 의료서비스가 발생하지 않도록 의료비 지원방안도 마련되어야 한다.

Purpose: The purpose of this study was to identify the difference in health behavior according to the anger expression styles in patients with coronary arteries disease. Methods: Participants included 99 patients with coronary artery disease who were treated with a percutaneous coronary intervention in K University Hospital in Seoul, from January to March 2012. The survey data were collected using the Anger Expression Inventory Korea Version and the Health Promoting Lifestyle Profile Version 2. The data were analyzed using descriptive statistics, acluster analysis, chi-square test,and ANOVA with the PASW 19.0program. Results: The anger expression styles identified from the cluster analysis were anger-control type(43.3%), anger-in/out type(42.4%), and high anger expression type(14.4%). The total score of the Health Promoting Life style Profile for the anger-control type was significantly higher than the other two types. Additionally, anger-control type showed significantly higher scores than the other two types in all domains of the Health Promoting Life style Profile. Conclusion: These results indicated that higher levels of anger-in and anger-out increased the risk of adverse health behavior and that anger control strategies could have some benefit in reinforcing healthy behavior in patients with coronary artery disease.

Objective: Although guideline recommends beta blockers (BBs) as first line antianginal agent and calcium channel blockers (CCBs) as alternatives after percutaneous coronary intervention (PCI), the prescription patterns in real practice are not in accordance with the guideline. We aimed to investigate the prescribing patterns of primary antianginal drug and relating factors in patients who underwent PCI. Methods: Patients who have undergone PCI without myocardial infarction (MI) from November 2012 to June 2014 and followed up at least one year in a tertiary teaching hospital were included. Prescribing patterns of primary antianginal drug before, at the time of, and one year after PCI were described. Factors affecting drug selection, and their relationship with incidence of clinical outcomes defined as MI and repeated PCI, unscheduled admission or visit related with heart problem were analyzed with multivariate logistic regression. Results: A total of 506 patients were included and as primary antianginal drugs, BB, CCB, and both were prescribed in 32.2%, 24.5%, and 17.8% of patients, respectively. Also, neither BB nor CCB was prescribed at the time of PCI in 25.5% of patients. Compared with BB, CCBs were more likely prescribed in patients who had hypertension (Odds Ratio, OR 2.18, 95% confidence interval, CI 1.16-4.07), use of same class before PCI (OR 7.18, 3.37-15.2) and concomitant angiotensin receptor blocker (ARB) use (OR, 1.92, 95% CI 1.10-3.33). Incidence of clinical outcomes were not significantly greater in patients who prescribed CCB compared with BB at the time of PCI (aOR 1.32, CI 0.65-2.68). Conclusion: This study demonstrated that half of the patients who underwent PCI were prescribed BB. CCB were favored in patients with hypertension, use of same class before PCI, and concomitant ARB use. Significant difference in clinical outcome was not observed between BB and CCB selection as primary antianginal drug.

Background and Objectives: We evaluated the effect of diabetes on the relationship between body mass index (BMI) and clinical outcomes in patients following percutaneous coronary intervention (PCI) with drug-eluting stent implantation. Methods: A total of 6,688 patients who underwent PCI were selected from five different registries led by Korean Multicenter Angioplasty Team. They were categorized according to their BMI into the following groups: underweight (<18.5 kg/m²), normal weight (18.5-24.9 kg/m²), overweight to obese (≥25.0 kg/m²). Major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of death, nonfatal myocardial infarction, stroke, and target-vessel revascularization, were compared according to the BMI categories (underweight, normal and overweight to obese group) and diabetic status. All subjects completed 1-year follow-up. Results: Among the 6,688 patients, 2,561 (38%) had diabetes. The underweight group compared to normal weight group had higher 1-year MACCE rate in both non-diabetic (adjusted hazard ratio [HR], 2.24; 95% confidence interval [CI], 1.04-4.84; p=0.039) and diabetic patients (adjusted HR, 2.86; 95% CI, 1.61-5.07; p<0.001). The overweight to obese group had a lower MACCE rate than the normal weight group in diabetic patients (adjusted HR, 0.67 [0.49-0.93]) but not in non-diabetic patients (adjusted HR, 1.06 [0.77-1.46]), with a significant interaction (p-interaction=0.025). Conclusions: Between the underweight and normal weight groups, the association between the BMI and clinical outcomes was consistent regardless of the presence of diabetes. However, better outcomes in overweight to obese over normal weight were observed only in diabetic patients. These results suggest that the association between BMI and clinical outcomes may differ according to the diabetic status.

Purpose: The purpose of this study was to identify the factors that predict discomfort after coronary angiography or percutaneous coronary intervention (PCI) among hospitalized patients. Methods: A total of 203 patients who underwent coronary angiography or PCI were recruited from C hospital located in S city, J province, from June through August 2008. The level of discomfort was measured and standardized by two instruments, discomfort questionnaire and the Visual Analogue Scale (VAS). Results: Stepwise multiple regression showed that the factors predicting the level of discomfort were type of angiography, gender, previous angiography, dysuria, pre-information, and sleep satisfaction, which together explained 30.6% of the total variance of the level of discomfort. Conclusion: Patients who had previous experience with these procedures, received a pre-information about the upcoming procedure, had no dysuria, and had slept well after the procedure were less likely to complain discomfort. Pre-informed education should be given by nurses to patients who will have an angiography or PCI to reduce their physical and emotional discomforts.
