We have experienced a case of coronary artery bypass surgery without extracorporeal circulation through limited anterior thoracotomy. The lesion was a single vessel disease involving the take off of the left anterior descending artery(LAD) which showed tubular lesion with irregular contour and eccentric stenosis of more than 95% luminal narrowing. Percutaneous transluminal coronary angioplasty(PTCA) seemed to have moderate success rate and moderate complication rate. A segment of left internal mammary artery(LIMA) from the second rib down to the sixth rib was harvested through the bed of resected fourth costal cartilage. Anastomosis between LIMA and LAD was performed under beating condition. The patient was extubated in the operation room and showed excellent postoperative course without complications. The coronary angiography on the postoperative 7th day revealed good patency at the anastomosis site.

Purpose: The purpose of this study was to identify influence of health behavior in patients with coronary artery disease. Methods: A cross-sectional descriptive design included 150 patients treated with percutaneous coronary intervention in S hospital in S city. Data were collected by using self-questionnaires July 5-August 26, 2021 and were analyzed by descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients, and multiple regression with SPSS 23.0. Results: Factors significantly influencing health behavior in patients with coronary artery disease were health empowerment (β = .48, p< .001), and post-traumatic growth (β = .20, p= .013). The explanatory power of related variables was 39%. Conclusion: Based on the this study, it was found that health empowerment and post-traumatic growth had a significant effect on the health behavior of patients with coronary artery disease. Thus, it is necessary to promote the health behavior of patients with coronary artery disease through the development of intervention programs to improve health empowerment and post-traumatic growth.

Background: There are several modalities of coronary artery revascularization for multivessel coronary artery disease. Hybrid coronary revascularization (HCR) with minimally invasive direct coronary artery bypass grafting was introduced for high-risk patients, and recently, many centers have been using it. Limited incisional full sternotomy coronary artery bypass (LIFCAB) involves left internal thoracic artery (LITA)-to-left anterior descending coronary artery (LAD) anastomosis through a sternotomy with a minimal skin incision; it could be considered another technique for minimally invasive LITA-to-LAD anastomosis. Our center has performed HCR using LIFCAB, and in this paper, we report our short-term results, obtained in the past 3 years. Methods: The medical records of 38 patients from May 2010 to June 2013 were analyzed retrospectively. The observation period after HCR was 1 to 37 months (average, $18.3{\pm}10.3$ months). The patency of revascularization was confirmed with postoperative coronary angio-computerized tomography or coronary angiography. Results: There were 3 superficial wound complications, but no mortalities. All the LITA-to-LAD anastomoses were patent in the immediate postoperative and follow-up studies, but stenosis was detected in 3 cases of percutaneous coronary intervention. Conclusion: HCR using LIFCAB is safe and yields satisfactory results from the viewpoint of revascularization for multivessel disease.

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.

Purpose: This study was aimed to explore and describe the experiences of mindfulness meditation (mindfulness- based stress reduction, MBSR) among patients with coronary artery disease (CAD) as a method of cardiac rehabilitation. Methods: In-depth interviews was conducted with 7 participants with CAD post percutaneous coronary intervention. Main question was 'what is your experiences with MBSR?' Colaizzi's seven steps of phenomenological analysis was used for eliciting embedded meanings. Results: Five theme clusters were found; rediscovery of mindfulness meditation, obtaining self-control for stress management, self-worth, feeling of happiness, and looking into myself. Conclusion: This study provides a profound picture on the experiences of mindfulness meditation among participants with coronary artery disease. MBSR can help patients with CAD in reducing stress and to enhance their cardiac rehabilitations. It is hoped that mindfulness meditation can be used in clinical setting as a part of cardiac rehabilitation program.

Purpose: This study assessed the effectiveness of hand massage on reducing discomfort of patients undergoing percutaneous coronary intervention(PCI). Methods: The sample consisted of 62 patients admitted to an university affiliated hospital. The 30 patients in experimental group received hand massage developed by Snyder(1995) for 5 minutes on both hands and 32 patients in control group received the usual nursing intervention only. The outcome variable of discomfort was measured 10 minutes before and after the hand massage using Questionnaire and VAS. The data were collected from Feb. 5th to May 17th in 2007, and analysed through Chi-square, and t-test with SPSS WIN 12.0. Results: The level of discomfort measured with the questionnaire was decreased in experimental group, but increased in control group. This discomfort changes in two groups were significantly different(t=4.43, p<.001). The level of discomfort measured with VAS was also decreased in experimental group, but increased in control group. The changes were significant, too(t=5.62, p<.001). Conclusion: It was clear that hand massage could be a useful nursing intervention in reducing the discomfort of patients undergoing PCI.

Objectives : The aim of this study was to investigate the relationship among uncertainty, self-care agency and physiological index in acute myocardial infarction (AMI) patients who underwent primary percutaneous coronary intervention. Methods : A total of 196 patients who were admitted C National University Hospital from Oct 2014 to Jun 2015 participated in the study. Data were collected with a questionnaire, and the blood pressure, HgA1C, and lipid profile levels of the patients were acquired. Results : The mean age was 69.2 (${\pm}13.0$) years, and 74 % of the patients were men. The mean score for uncertainty in illness was 48.7 (${\pm}8.8$). The mean score for self-care agency was 73.3 (${\pm}13.4$). Self-care agency showed a negative correlation with uncertainty (r=-.579, p<.001), age (r=-.732, p<.001), systolic blood pressure (r=-.265, p=.001) and HgA1C (r=-.293, p<.001). Conclusions : The results of this study can be used to develop a nursing program that prevents AMI and to improve the clinical prognosis of AMI patients.

From 1985 through Oct. 1988, we have experienced 5 cases of Aorto-Coronary Bypass Surgery [ACBS] and 3 cases of Percutaneous Transluminal Coronary Anogioplasty [PTCA]under the diagnosis of unstable angina. There were 6 males and 2 females who ranged from 48 to 70 years old. Almost all patients had a evidence of hypertension & hyperlipidemia. Two patients showed old myocardial infarction and remaining patients showed myocardial ischemia on resting state. The patterns of involvement of coronary artery disease were single vessel disease [4 cases], double vessel disease [3 cases], Triple vessel disease [1 case]. Among 5 cases of ACBS, double bypass graft was in 3 cases and single bypass graft was in 2 cases. Mode of anastomosis were all individual anastomosis, using Saphenous vein graft. Postoperative complications were perioperative myocardial infarction [2 cases], postoperative bleeding [1 case], leg wound disruption [1 case]. Perioperative myocardial infarction cases didn*t survive. In cases of PTCA, there were no complications. Follow up periods were ranged from 1 month to 25 months. All survived cases were asymptomatic except one case, who showed Functional Class II.

Transradial access is a widely accepted method for percutaneous coronary diagnostic and interventional procedures, and it has dramatically reduced access site vascular complications compared to transfemoral access. Arteriovenous fistula formation at the access site is an especially rare complication in transradial access. We report an extremely rare case of delayed radial arteriovenous fistula that developed one year after transradial coronary angiography, which was successfully treated by surgical repair.

Background: The possibility of incomplete revascularization and development of flow competition after revascularization of the borderline lesion made the hybrid strategy as an option for complete revascularization. Material and Method: From January f998 to July 2004, 25 $(3.2\%)$ patients underwent hybrid revascularization among 782 total OPCAB procedures. Clinical results and angiographic patencies were evalulated. Percutaneous coronary intervention (PCI) was peformed before CABG in 8 patients and after CABG in 47 patients. Result: The causes of PCIs before CABG were to achieve complete revascularization with minimally invasive surgery (n=7) and emergent PCI for culprit lesion (n=1). The indications of PCIs after CABG were high possibility of flow competition in the borderline lesion of right coronary artery territory (n=8), diffuse atheromatous lesion preventing anastomosis of graft (n=5), severe calcified ascending aorta with no more arterial grafi available (n=3), and intramyocardial coronary lesion (n=1). Mean number of distal anastomoses was $2.3\pm1.0$. Mean number of lesions treated by PCI was $1.2\pm0.4$. There was no operative or procedure-related mortality. PCI-related complication was periprocedural myocardial infarction in one patient, and complications related to CABG were transient atrial fibrillation (n=5), perioperative myocardial infarction (n=1), and transient renal dysfunction (n=1). Early postoperative coronary angiography $(1.8{pm}1.6days)$ revealed $100\%$ patency rate of grafts (57/57). The stenosis occurred in one patient performed PCI before CABG, which was successfully treated with re-ballooning. During midterm follow-up (mean; $25{\pm}26$ months), 1 patient died of congestive heart failure. All survivors (n=24) accomplished follow-up coronary angiographics, which showed .all grafts (56/57) were patent except one string sign. In-stent restenosis was developed in 2 patients who received bare metal stents. Conclusion: In selected patients, complete revascularization was achieved with low risk by taking the hybrid strategy.
