With the recent development of technologies to manage vast amounts of data, data mining technology has had a major impact on all industries.. Data mining is the process of discovering useful correlations hidden in data, extracting executable information for the future, and using it for decision making. In other words, it is a core process of Knowledge Discovery in data base(KDD) that transforms input data and derives useful information. It extracts information that we did not know until now from a large data base. In the decision tree, c4.5 algorithm was used. In addition, the C4.5 algorithm was used in the decision tree to analyze the difference between frequency and mortality in the region. In this paper, the frequency and mortality of percutaneous coronary intervention for patients with heart disease were divided into regions.

Purpose: The purpose of this study was to explore the differences of health locus of control and treatment compliance according to general characteristics and severity in acute coronary syndrome(ACS) patients after percutaneous coronary intervention. Methods: This descriptive study was conducted with a convenient sample of 103 ACS patients. The dependent variables were measured by the scales for the Multidimensional Health Locus of Control and the Treatment Compliance. The collected data were analyzed by the Fisher's exact test, Chi-square and t-tests, and ANOVA using the SPSS program. Results: Pre-interventional severity was significantly different between men and women. In terms of internal health locus of control, there was a significant difference according to gender, educational status, economic status, and severity. The level of medication compliance was the lowest among the sub-scales of treatment compliance. Conclusion: These findings suggest that clinical nurses should evaluate the general characteristics and severity of the patients with ACS for providing tailored nursing interventions.

This study is a descriptive study to understand the effect on the health behavior compliance of men who got coronary intervention, focusing on the elapsed period. The subjects of this study were 249 men who underwent coronary intervention at a university hospital, and the collected data were analyzed using Stepwise multiple regression. As a result of the study, the influencing factors the implementation of healthy behaviors were self-regulation(β=0.35, p<.001), risk factors among educational request(β=-0.26, p<.001), and the elapsed period(β=0.19, p<.001), marital status(β=0.15, p=.001), educational level(β=-0.12, p=.035), and the total explanatory power was 29.1%. IIn order to increase the health behavior performance of male patients who underwent coronary intervention, it is necessary to develop a program that can strengthen the autonomous motivation of subjects with high severity and elapsed time of less than 1 year and more than 1 year.

Coronary stent dislodgement during percutaneous coronary intervention, which occurs when the stent is passed through tortuous and calcified lesions, is not a rare complication. Without proper treatment, such as fixing with another stent in the coronary artery or removing the undeployed stent from the coronary artery or systemic artery system, this complication can cause serious problems. We experienced the unusual situation of a dismounted and dislodged coronary stent, in which retrograde retrieval to the radial artery was impossible during transradial coronary intervention. We report on use of a rendezvous and snare technique at the brachial artery level via femoral puncture, which resulted in resolution without surgery.

Background: Serum copeptin has been demonstrated to be useful in early risk stratification and prognostication of patients with acute myocardial infarction (AMI). However, the prognostic value of copeptin after percutaneous coronary intervention (PCI) for clinical outcomes remains uncertain. We investigated the prognostic role of serum copeptin levels immediately after successful PCI as a prognostic marker for major adverse cardiac events (MACE; comprising death, repeat PCI, recurrent MI, or coronary artery bypass grafting) in patients with AMI. Methods: A retrospective study was performed in 149 patients with AMI who successfully received PCI. Serum copeptin levels were analyzed in blood samples collected immediately after PCI. The association between copeptin levels and MACE during the follow-up period was evaluated. Results: MACE occurred in 34 (22.8%) patients during a median follow-up of 30.1 months. MACE patients had higher copeptin levels than non-MACE patients did. Multiple logistic regression analysis showed that the increase in serum copeptin levels was associated with increased MACE incidence (odds ratio=1.6, P =0.005). Conclusions: A high level of serum copeptin measured immediately after PCI was associated with MACE in patients with AMI during long-term follow-up. Serum copeptin levels can serve as a prognostic marker in patients with AMI after successful PCI.

Postcardiac injury syndrome (PCIS) is an inflammatory process that usually occurs within 1 to 6 weeks after an injury to the pericardium, epicardium, or myocardium. As more interventions are performed for complicated coronary artery obstructive lesions, there have been some recent reports on PCIS following percutaneous coronary intervention (PCI). The medical management of PCIS depends on nonsteroidal anti-inflammatory drugs (NSAIDs), in addition to colchicine or steroids. An 80-year-old male patient underwent a PCI. Unfortunately, the guidewire piercing failed but he showed no immediate signs of complication. However, 5 hours after the procedure, he complained of chest discomfort. An electrocardiogram showed widespread ST elevation. Chest X-ray and computed tomography showed pulmonary congestion with pleural effusion, while thoracic echocardiography showed a moderate amount of pericardial effusion. NSAIDs were initiated, but there was no improvement of symptoms. We describe an unusual case of atypical earl onset PCIS after PCI, recovered rapidly by steroids.

This systematic review evaluates the clinical effectiveness of acupuncture related to improvement in quality of life and problems after Percutaneous Coronary Intervention(PCI). We searched papers in many databases, including National Discovery for Science Leaders(NDSL), Koreanstudies Information Service System(KISS), Oriental Medicine Advanced Searching Integrated System(OASIS), Research Information Sharing Service(RISS), Public/Publisher MEDLINE(Pubmed), Embase, Cochranelibrary, Chinese Academic Journals(CAJ), Japan Science and Technology Agency(J-STAGE). Initially, 161 studies were found. Of these, 141 studies were excluded following abstract screening. After the remaining 20 papers were scanned, 5 RCTs were selected and analyzed. Among these 5 RCTs, HAMD(Hamilton Rating Scale for Depression) is significantly effective in 1 RCT. In 2 RCTs, LVEF(Left Ventricular Ejection Fraction) is significantly effective. In 2 RCTs, 6MWT(Six-Minute Walk Test) is significantly effective. The review of 5 studies suggests that acupuncture after PCI can be effective in many problems occured after PCI. However, This study couldn't conduct a meta-analysis due to the differences in interventions. Therefore, we hope that systematic reviews with meta-analysis will be published.

The most common cause of a heart attack is known as coronary artery disease, which narrows the arteries and reduces the blood flow to the heart. To treat coronary artery stenosis, percutaneous coronary intervention (PCI) (a nonsurgical procedure to install a stent, which holds the artery wall open) is performed. Intracoronary optical coherence tomography (OCT) is a catheter-based, invasive optical imaging system. To determine whether PCI is appropriate, and to perform stent evaluation in a catheterization laboratory, OCT examinations are carried out. This review details the fundamental principles and technological status of intracoronary OCT imaging, and discusses the ongoing clinical applications to determine the benefits of OCT-guided PCI.

Stent entrapment is a very rare complication of percutaneous coronary intervention. The interventional approach could be a treatment strategy. However, if it does not work, surgical treatment should be considered. Here, we report a case of surgical treatment of stent entrapment in the left coronary sinus of a 53-year-old male patient.

Major cardiac complication such as acute myocardial infarction can occur unexpectedly in patients without risk factors. We experienced cardiac arrest due to an unexpected acute myocardial infarction in a patient without any risk factors during head and neck reconstructive surgery. The patient was diagnosed with acute myocardial infarction after return of spontaneous circulation. With immediate percutaneous coronary intervention, the patient recovered without complications.
