Ventricular septal rupture (VSR) is a rare but lethal complication of myocardial infarction. The event occurs 2~8 days after an infarction and often precipitates cardiogenic shock. Post myocardial infarction VSR is known for difficult to repair. Especially, Transmural myocardial infarction involved in the posterior VSD area, exposure of the affected site is difficult and postoperative mortality rate is high. We have experienced a case of a 75-year-old female patient who suffered posterior VSD due to acute myocardial infarction, and attained good result by approaching the lesion through right atrial incision and repaired the defect by using patch closure technique.

저자들은 금성심근경색증으로 진단된 36명에서 응급실 도착후에 시행한 Tc-99m seataMIBl 심근 SPECT를 심전도검사와 비교하여 다음의 결과를 얻었다. 1) 좌전하행관동맥과 우관동맥의 폐쇄로 인한 심근 경색증환자 24명 모두가 안정기 Tc-99m sestamibi 심근 SPECT에서 관류결손을 나타냈고, 심전도상에서는 Q파 혹은 ST절의 상승이 관찰되었다. 2) 좌회선관동맥의 폐쇄로 인한 심근경색증환자 7명 모두 안정기 Tc-99m sestamibi 심근 SPECT에서 측벽에 관류결손이 나타났으나, 이상 Q파는 1명에서만 관찰되었고, 6명에서 ST절의 변화가 보였으며, 1명에서는 정상심전도소견을 보였다. 3) 심혈관촬영술을 시행하지 않은 3예중 2예에서는 심전도상 경색의 위치와 심근 SPECT에서의 관류결손부위가 일치하였으나, 나머지 1예에서는 심전도상 LBBB가 보였고 심근SPECT에서는 하벽에 관류결손이 관찰되 었다. 4) 극성지도를 이용하여 구한 손상된 심근의 면적을 전체심근에 대한 백분율로 표시하면 좌전하행관동맥 : $31.17{\pm}18.21%$, 우관동맥 : $31.17{\pm}13.24%$, 좌회선관동맥 : $24.71{\pm}5.94%$ 이었다. 5) 정성적인 분석에서 심근경색의 진단적 예민도는 100%였고, 관동맥 조영술을 시행하여 경색 관련 관동맥을 진단할 수 있었던 31명의 모든 예에서 심근관류 SPECT로 국소화가 가능하였다. 이상의 결과에서 응급으로 시행한 심근관류 SPECT가 심근경색의 진단에 유용하며, 특히 심전도에서 심근경색증의 판단이 어려운 측벽경색이나 좌각차단이 있는 경우에 유용한 방법으로 생각된다.

Purpose: The purpose of this study was to examine the effects of the cardiac rehabilitation program(Phase III) on cardiovascular and cardiorespiratory function in the elderly (age, ${\geq}$ 60) who experienced acute myocardial infarction. Methods: The design of research was nonequivalent control group pretest-posttest design. Subjects were 10 people in the experimental group and 10 in the control group. The intervention program was the cardiac rehabilitation program(Phase III), and was performed for 50 ~ 60 minutes, twice a week for 8 weeks. The dependent variables were the cardiovascular and cardiorespiratory function. Results: Significant differences were shown in RHR, RSBP, SRPP, SBS, BMI, PT of the experimental group after the intervention. As for the differences in the amount of changes, there were differences among groups in RHR, RSBP, SRPP, SBS, PMET, and PT of the experimental group. Conclusion: The cardiac rehabilitation program(Phase III) may be effective in improving cardiovascular function and enhancing cardiorespiratory function in elderly patients with acute myocardial infarction.

Cardiogenic syncope occurs due to arrhythmia (bradycardia and tachycardia) or decreased cardiac output, and if proper treatment is not provided, it can lead to acute sudden death. A detailed medical history and physical examinations are required to determine the cause of syncope, and clinical approaches, including 12-lead ECG, are important. The 12-lead ECG does not have a chest lead in the posterior wall of the left ventricle; therefore, ECG of the isolated posterior wall myocardial infarction caused by left circumflex artery occlusion is not observed with ST elevation. Therefore, the significantly higher appearance of ST depression and R waves than S waves from V1 to V3 of the chest lead must be interpreted meaningfully. Isolated posterior wall myocardial infarction is small in the area of myocardial necrosis, and tension is increased in the necrotic area due to the contraction of the normal myocardial muscle, which can cause ventricular wall rupture. Therefore, it is necessary to additionally check Beck's triad, such as jugular venous distension and decreased heart sound, in patients with low blood pressure with an isolated posterior wall myocardial infarction on 12-lead ECG in patients with syncope.

Myocardial infarction (MI) secondary to coronary artery fistula and the subsequent occlusion of the distal right coronary artery (RCA) after blunt chest trauma is a rare entity. Here, we describe a case of coronary artery fistula and occlusion with an inferior MI that occurred following blunt chest trauma. At the initial visit to the emergency room after a car accident, this patient had been undiagnosed with acute myocardial infarction, readmitted five months after ischemic insult, and revealed to have experienced MI due to RCA-right atrial fistula and occlusion of the distal RCA. He underwent coronary surgery and recovered without complications.

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.

본 연구는 급성심근경색증 입원환자를 대상으로 중증도가 보정된 적정 재원일수 예측모형을 개발하여 의료의 질 관리 및 정책 개발에 필요한 기초자료를 제시하고자 하였다. 2004-2006년 퇴원손상심층조사 자료 중 급성심근경색증 입원환자 2,309명을 대상으로 급성심근경색증 입원환자의 적정 재원일수 예측모형은 데이터마이닝을 이용하여 개발하였다. 의사결정나무 모형에 따라 급성심근경색증 입원환자의 평균재원일수에 가장 큰 영향을 미치는 변수는 관상동맥우회술(CABG)과 동반질환 건수로 나타났다. 앙상블 모형을 이용하여 개발된 급성심근경색증 입원환자의 중증도 보정 재원일수 모형 결과, 적정 재원일수와 실제 재원일수의 차이는 보험유형과 의료기관 소재지가 통계적으로 유의하게 나타났다. 따라서 재원일수의 변이를 줄이고 효율적으로 관리하기 위해 의료기관에서는 다빈도 질환에 대한 중증도 보정 적정 재원일수 예측모형을 개발하여 이를 의료정보시스템에 적용하고 관리하는 활동을 전개해야 할 것이다.

Extra-corporeal membrane oxygenation (ECMO) has the potential to rescue patients in cardiac arrest or respiratory failure. ECMO has two systems such as veno-arterial and veno-venous circulation. In cardiac arrest resulting from acute myocardial infarction, veno-arterial ECMO is mandatory for systemic circulation and oxygenation. A 75-year old female patient underwent primary coronary intervention for acute myocardial infarction. Despite successful revascularization, recurrent ventricular tachycardia and heart failure were progressing. We performed a veno-arterial ECMO through the femoral artery and vein, then the patient seemed to be stable clinically. However, laboratory studies, echocardiography, and vital signs indicated multi-organ failure and decreasing cardiac function. We found out an error that we performed veno-venous ECMO instead of veno-arterial ECMO. We added a femoral artery cannula and exchange the circuit system to veno-arterial ECMO. While the systemic circulation seemed to be recovered, the left ventricular function was decreased persistently. A hypovolemia resulting from pulmonary hemorrhage was occurred, which lead to ECMO failure. The patient died of cardiac arrest and multi-organ failure 23 hours after ECMO. Because the color of arterial and venous circuits represent the position and efficacy of ECMO, if unexpected or abnormal circuit colors are detected, prompt and aggressive evaluation for ECMO function is mandatory.

흉부 외상은 단순 부정맥에서 심근 파열 등 심장에 다양한 합병증을 일으킬 수 있다. 그중 관상동맥 손상은 매우 드문 합병증이고 특히 좌측 관상 동맥의 동맥류는 우측에 비해서 발생빈도가 작은 것으로 되어있다. 흉부 둔상 후 관상 동맥 내벽의 동맥류 형성, 박리, 열상, 동정맥루 및 혈전 등이 매우 드물게 생길 수 있으며, 혈관이 막히고 심근 경색이 발생하면 환자에게 치명적인 손상을 일으킨다. 교통사고로 인한 흉부의 둔상 후 발생한 심근경색증을 진단받은 33세 남자에서 관상동맥 우회로술을 통해 좋은 결과를 얻었기에 보고하는 바이다.

The importance of the diseases which are differentiated with acute myocardial infarction (AMI) cannot be overemphasized in insurance medicine. Although there are lots of diseases similar with AMI, in this paper, 5 diseases were described; Myocardial bridging, cocaine toxicity, myocarditis, cardiac syndrome X, and Takotsubo syndrome. Costs of the interventions like coronary angiography or echocardiography are relatively low in Korea compared to western countries. Therefore, detection of those diseases has been increased recently and illegal drug addiction also has been increased probably due to globalization. In conclusion, the knowledge of those diseases dealt with this article could be helpful for the person who is related to insurance medicine.
