Background/Aims: Chest pain is an essential symptom in the diagnosis of acute coronary syndrome (ACS). One-third of patients with ACS present atypically, which can influence their receiving timely lifesaving therapy. Methods: A total of 617 NSTEMI patients from the Korea Acute MI Registry (KAMIR) and the Korea Working Group on MI (KorMI) databases were analyzed. The study population was divided into two groups by symptoms at presentation (typical symptoms group, 128; atypical symptoms groups, 128). Results: In this study population, 23% of patients presented without chest pain. After propensity score matching, the contact-to-device time ($2,618{\pm}381minutes$ vs. $1,739{\pm}241minutes$, p = 0.050), the symptoms-to-balloon time ($3,426{\pm}389minutes$ vs. $2,366{\pm}255minutes$, p = 0.024), and the door-to-balloon time ($2,339{\pm}380minutes$ vs. $1,544{\pm}244minutes$, p = 0.002) were significantly higher in the patients with atypical symptoms than in those with typical symptoms, respectively. Atypical symptoms were an independent predictor for 1-year mortality (hazard ratio, 2.820; 95% confidence interval, 1.058 to 7.515; p = 0.038). The Kaplan-Meier estimates showed higher risk for 12-month mortality in patients with atypical symptoms (p = 0.048) and no significant difference for 12-month major adverse cardiac events (p = 0.487). Conclusions: Acute myocardial infarction patients with atypical symptoms were not rare in clinical practice and showed a high risk of delayed reperfusion therapy. After imbalance between the groups was minimized by use of propensity score matching, patients who presented atypically had a high mortality rate.

본 연구는 2010년 1월 1일부터 2011년 12월 31일까지 2년간 119구급대로 이송된 병원 전 제세동 가능한 심정지 환자를 대상으로 연구를 진행하였으며 연구대상자들의 구급활동일지와 구급지령서를 분석하였다. 119구급상황관리센터 상황요원(Dispatcher)이 가장 많이 예측한 지령은 실신으로 74건(33.3%)이었다. 다양하게 예측된 지령 중 실신, 흉통, 전신쇠약, 기타와 같은 지령은 심정지로 예측 불가능한 지령으로 112건(50.5%)을 차지하였으며, 심정지로 예측 가능한 의식장애, 호흡곤란, 무호흡, 심정지, 경련과 같은 지령은 110건(49.5%)을 차지하였다. 이 때 심정지로 예측 가능한 지령에서 목격자의 심폐소생술이 유의하게 높았다. 이와 같이 상황요원은 환자의 의식평가와 호흡평가를 구체적으로 질문하여 심정지를 정확하게 분류해야하며, 이렇게 분류된 심정지 환자는 목격자가 심폐소생술을 할 수 있도록 지도해야 한다. 또한 상황요원에 의해 심정지로 예측 가능한 지령(49.5%)을 받은 구급대원뿐만 아니라 심정지로 예측 불가능한 지령(50.5%)에서도 심정지가 아니라고 정확하게 판단되지 않았다면 현장 구급대원은 심정지 상황에 대비하여 현장출동 준비를 해야 한다.

A 55-year-old woman who had a history of percutaneous vertebroplasty was referred to our institution with sudden onset of chest pain. Computed tomography (CT) scan demonstrated a long, linear, highly-attenuated segment in the right side of the heart and fragmented pieces in the right pulmonary artery. The CT scan and echocardiogram revealed no pericardial effusion or hemopericardium. Based on these findings, we performed surgery through right anterolateral thoracotomy without cardiac arrest. As a result, we safely removed the foreign body. This approach may be a feasible and effective procedure for selected cases.

We present a case of left ventricular pseudoaneurysm, which is a very rare and fatal complication of cardiac procedures such as mitral valve replacement. A 55-year-old woman presented to the Department of Thoracic and Cardiovascular Surgery at Hanyang University Seoul Hospital with chest pain. Ten years prior, the patient had undergone double valve replacement due to aortic regurgitation and mitral steno-insufficiency. Surgical repair was successfully performed using a prosthetic pericardial patch via a left lateral thoracotomy.

Background: In this study, we examined the impact of a patient blood management (PBM) program on red blood cell (RBC) transfusion practices in cardiothoracic surgery. Methods: The PBM program had 3 components: monitoring transfusions through an order communication system checklist, educating the medical team about PBM, and providing feedback to ordering physicians on the appropriateness of transfusion. The retrospective analysis examined changes in the hemoglobin levels triggering transfusion and the proportions of appropriate RBC transfusions before, during, and after PBM implementation. Further analysis was focused on patients undergoing cardiac surgery, with outcomes including 30-day mortality, durations of intensive care unit and hospital stays, and rates of pneumonia, sepsis, and wound complications. Results: The study included 2,802 patients admitted for cardiothoracic surgery. After the implementation of PBM, a significant decrease was observed in the hemoglobin threshold for RBC transfusion. This threshold dropped from 8.7 g/dL before PBM to 8.3 g/dL during the PBM education phase and 8.0 g/dL during the PBM feedback period. Additionally, the proportion of appropriate RBC transfusions increased markedly, from 23.9% before PBM to 34.9% and 58.2% during the education and feedback phases, respectively. Among the 381 patients who underwent cardiac surgery, a significant reduction was noted in the length of hospitalization over time (p<0.001). However, other clinical outcomes displayed no significant differences. Conclusion: PBM implementation effectively reduced the hemoglobin threshold for RBC transfusion and increased the rate of appropriate transfusion in cardiothoracic surgery. Although transfusion practices improved, clinical outcomes were comparable to those observed before PBM implementation.

배경: 최소 침습성 심장수술은 기존의 정중 흉골절개술보다 우수한 미용효과, 흉곽 개폐에 있어서의 용이함, 작은 외상에 따른 통증, 감염, 출혈 등의 감소, 빠른 회복 및 재원일수의 감소 등이 장점으로 제시되면서 점차 널리 시행되고 있다. 대상 및 방법: 저자들은 1997년 3월부터 12월 까지 36명의 환자를 대상으로 우측 방정중 절개법, 흉골횡 절개법, 최소흉골절개법 등의 3가지 접근방법으로 대동맥 판막 및 승모판 판막질환, 선천성 심기형의 환자 등에 대해 최소 침습성 심장수술을 시행하였다. 결과: 사망례는 없었다. 합병증으로는 술후 부정맥 4례, 출혈로 인한 재수술 1례, 창상 지연유합 1례가 있었다. 사용된 창상의 평균 길이는 9.1$\pm$0.9cm이었고 중환자실 체류기간은 평균 48$\pm$29시간, 술후 재원기간은 평균 10$\pm$7일 이었다. 결론: 술중 제세동, 탈기, 심장감압 등의 과정에 있어서 어려운 점이 있고 아직까지는 선별된 예에 한해 시행되고 있으나 경험의 축적에 따라 점차 그 적용례가 늘어날 것이라 전망된다.

Purpose: This study was conducted to examine and compare clinical manifestations and predicting factors for treatment-seeking delay among patients <65 and ${\geq}65\;yr$ with first-time acute coronary syndrome (ACS). Methods: A total of 288 patients who were diagnosed with ACS were individually interviewed at C university hospital in G-city from November 2007 to December 2008. Results: Median pre-hospital delays for younger and older patients were 5 and 12 hr, respectively. Younger patients were more likely to be current smokers, heavy drinkers, obese, stressed, and have an unhealthy diet and family history, and to complain of chest pain, left shoulder and arm pain, perspiration, and nausea. Older patients were more likely to have hypertension and diabetes, and to complain syncope and dyspnea. Logistic regression analyses showed that after adjustment for age, gender and education, progressive onset of symptom and no attribution to cardiac problem significantly predicted pre-hospital delay >3 hr in both younger and older patients. Low perceived health status was a significant independent predictor in older patients only. Conclusion: Health care providers should be concerned with different manifestations between younger and older adults, and educate people at risk for heart attack about symptoms and actions to get immediate help.

Gastroesophageal reflux disorder (GERD) refers to reflux of gastric contents into the esophagus leading to esophagitis, reflux symptoms (e.g. heartburn, regurgitation and non-cardiac chest pain) sufficient to impair quality of life, or long term complications. Non-erosive reflux disease (NERD), a subdivision of GERD, is diagnosed when there were some reflux symptoms without esophagitis and mucosal breaks at endoscopy. We report that severe NERD symptoms and lower quality of life which have not responded to more than 6 months' western medical therapy (acid suppression) were successfully improved with traditional oriental medicine.

Left main coronary artery (LMCA) thrombosis is rare and the cause should be determined. A previously healthy young man presented with severe chest pain and dyspnea. The electrocardiogram showed typical ST-segment elevation myocardial infarction with clinical instability. Emergency coronary angiography revealed complete LMCA occlusion by thrombosis. After reperfusion, the patient was admitted to the cardiac care unit. He was diagnosed with hemolytic anemia and tested positive for antinuclear antibodies. Systemic lupus erythematosus (SLE) and LMCA disease due to systemic thrombosis were diagnosed. Steroids were started and the patient was discharged without complications. We report this rare case of LMCA thrombosis as an initial presentation of SLE.
