Background: There are a lot of debates regarding the optimal timing of operation of acute myocardial infarction (AMI). Off pump coronary artery bypass grafting (OPCAB) has benefits by avoiding the adverse effects of the cardio-pulmonary bypass, but its efficacy in AMI has not been confirmed yet. The purpose of this study is to evaluate retrospectively early and mid-term results of OPCAB in patients with AMI according to transmurality and timing of operation. Material and Method: Data were collected in 126 AMI patients who underwent OPCAB between January 2002 and July 2005, Mean age of patients were 61.2 years. Male was 92 (73.0%) and female was 34 (27.2%). 106 patients (85.7%) had 3 vessel coronary artery disease or left main disease. Urgent or emergent operations were performed in 25 patients (19.8%). 72 patients (57.1%) had non-transmural myocardial infarction (group 1) and 52 patients (42.9%) had transmural myocardial infarction (group 2). The incidence of cardiogenic shock and insertion of intra-aortic balloon pump (IABP) was higher in group 2. The time between occurrence of AMI and operation was divided in 4 subgroups (<1 day, $1{\sim}3\;days,\;4{\sim}7\;days$, >8 days). OPCAB was performed a mean of $5.3{\pm}7.1$ days after AMI in total, which was $4.2{\pm}5.9$ days in group 1, and $6,6{\pm}8.3$ days in group 2. Result: Mean distal an-astomoses were 3.21 and postoperative IABP was inserted in 3 patients. There was 1 perioperative death in group 1 due to low cardiac output syndrome, but no perioperative new MI occurred in this study. There was no difference in postoperative major complication between two groups and according to the timing of operation. Mean follow-up time was 21.3 months ($4{\sim}42$ months). The 42 months actuarial survival rate was $94.9{\pm}2.4%$, which was $91.4{\pm}4.7%$ in group 1 and $98.0{\pm}2.0%$ in group 2 (p=0.26). The 42 months freedom rate from cardiac death was $97.6{\pm}1.4%$ which was $97.0{\pm}2.0%$ in group 1 and $98.0{\pm}2.0%$ in group 2 (p=0.74). The 42 months freedom rate from cardiac event was $95.4{\pm}2.0%$ which was $94.8{\pm}2.9%$ in group 1 and $95.9{\pm}2.9%$ in group 2 (p=0.89). Conclusion: OPCAB in AMI not only reduces morbidity but also favors hospital outcomes irrespective of timing of operation. The transmurality of myocardial infarction did not affect the surgical and midterm outcomes of OPCAB. Therefore, there may be no need to delay the surgical off-pump revascularization of the patients with AMI if surgical revascularization is indicated.

개그맨 김형곤씨의 갑작스런 죽음에 충격을 받은 많은 중년 남성들이 '심근경색'에 이목을 집중하고 있다. 같은 날 슬로보단 밀로셰비치 전 유고연방 대통령이 감방에서 사망했고, 그 전날에 성낙합 서울 중구청장이 집무실에서 숨졌는데, 이들의 사인 또한 급성 심근경색. 최근엔 우리나라의 40대 돌연사 비율이 경제협력개발기구(OECD) 국가 중 최고라는 통계까지 발표된 바 있다. 돌연사 공포증을 불러일으키고 있는 이 증상의 원인과 대책은 무엇일까.

Despite early aggressive treatment, post myocardial infarction(MI) ventricular septal defect(VSD) revealed high surgical mortality. We reviewed the 10-year experiences of surgically treated post-MI VSD in Yonsei University. Material and Method: From Jan. 1991 to May 2001, 17 patients underwent surgical repair of post-MI VSD. Ages ranged between 47 and 77 years(mean age＝63.2$\pm$9.1). There were 10 males and 7 females. VSD was located at anterior in 16 patients and at posterior in one. IABP was inserted preoperatively in 12 patients due to cardiogenic shock. Mean interval from MI to occurrence of VSD was 5.6 days. Among patients undergoing early surgical correction(n＝13), mean interval from occurrence of VSD to operation was 2.5 days. In 11 patients, concomitant CABG was performed during repair of VSD. Result: Four patients died within 30 days after the operation(30 day mortality＝23.5%). Among 12 patients with preoperative cardiogenic shock, 4 patients died within 30 days(30-day mortality＝33.3%). During mean follow up period of 52 months, one patient died of unknown cause and 10-year survival of discharged patients was 66.7%. All follow-up patients were in NYHA functional class I or II when their last OPD visit. Conclusion: In the treatment of post-MI VSD, aggressive medical treatment with early surgical correction seems to be very important in terms early and long-term survival of patients.

Background: Postinfarction ventricular septal rupture is associated with mortality as high as $85\sim90%$, if it is treated medically. This report documents our experience with postinfarction ventricular septal rupture that was treated surgically, Material and Method: We retrospectively reviewed the medical records of 11 patients who were operated on due to postinfarction ventricular septal rupture between August 1996 and August 2006. There were 4 men and 7 women, with a mean age of $70{\pm}11$ years (age range: $50\sim84$ years). The location of the rupture was anterior in 7 cases and posterior in 4 cases. The interval between the onset of acute myocardial infarction and the occurrence of the ventricular septal rupture was $2.0{\pm}1.3$ days (range: $1\sim5$ days). Operation was performed at an average of $2.4{\pm}2.7$ days (range: $0\sim8$ days) after the diagnosis of septal rupture. Preoperative intraaortic balloon pump therapy was performed in 10 patients. Result: The infarct exclusion technique was used in all cases. Coronary artery bypass grafting was done in 8 cases, with the mean number of distal anastomosis being $1.0{\pm}0.8$. There was one operative death. In 2 patients, reoperation was performed due to a residual septal defect. The postoperative morbidities were transient atrial fibrillation (n=7), paroxysmal supraventricular tachycardia (n=1), low cardiac output syndrome (n=3), bleeding reoperation (n=2), delayed sternal closure (n=2), acute renal failure (n=2), pneumonia (n=1), intraaortic balloon pump-related thromboembolism (n=1), and transient delirium (n=2). Nine patients have been followed up for a mean of $38{\pm}40$ months except for one follow-up loss. There have been 3 late deaths. At the latest follow-up, all 6 survivors were in a good functional class. Conclusion: We demonstrated satisfactory operative and midterm results with our strategy of preoperative intraaortic balloon pump therapy, early repair of septal rupture by infarct exclusion and combined coronary revascularization.

Background/Aims: It is well known that gender differences are associated with clinical outcomes in patients with acute myocardial infarction (AMI). However, it is not clear whether gender differences affect the prognosis of elderly patients with AMI. Methods: We analyzed the incidence of in-hospital complications and mortality in the Korea Acute Myocardial Infarction Registry-National Institutes of Health from November 2011 to June 2015. This study included elderly patients (≥ 75 years) diagnosed with AMI. Results: A total of 2,953 patients were eligible for this study. Among them, 1,529 (51.8%) patients were female, and the mean age of the female group was older than that of the male group (80.7 ± 4.4 vs. 79.6 ± 4.0 years, respectively, p < 0.001). Elderly females utilized emergency medical services less frequently compared with elderly males (11.5 vs. 15.4%, respectively, p < 0.001). Elderly female AMI patients had a similar rate of in-hospital mortality compared with elderly males (7.1 vs. 8.4%, respectively, p = 0.196). The rate of major cardiac adverse events (MACEs) was lower in elderly females than males during a 12-month follow-up (hazard ratio [HR] 1.19, 95% confidence interval [CI] 1.00-1.41, p = 0.045). According to multivariate analysis, the male gender is an independent factor for predicting 1-year MACEs (HR 1.37, 95% CI 1.14-1.65, p < 0.001). Conclusions: No significant differences in peri-procedural complications or in-hospital mortality were observed between male and female elderly patients with AMI. However, elderly female patients had a more favorable prognosis than male patients during a 1-year clinical follow-up.
