  • 심혈관 질환은 심장마비의 가장 흔한 원인으로 관상동맥의 협착으로 심근에 산소와 영양분을 제대로 공급하지 못하게 되어 발생하게 된다. 이를 내과적으로 치료하기 위해 심혈관 중재술이 시행되는데 이때 스텐트 삽입 여부, 위치, 크기, 그리고 스텐트 삽입 후 혈관벽과의 밀착 여부를 평가하기 위해 혈관 내 광간섭단층촬영(OCT, optical coherence tomography) 내시경 진단검사를 시행한다. 본 논문에서는 이러한 심혈관 OCT 원리와 기술 동향, 그리고 실제 의료현장에서 심혈관 OCT의 임상적 응용 및 활용가치를 소개하고자 한다.

  • Percutaneous coronary intervention (PCI) is used to treat obstructive coronary artery disease (CAD). The role of PCI is well defined in acute coronary syndrome, but that for stable CAD remains debatable. Although PCI generally relieves angina in patients with stable CAD, it may not change its prognosis. The extent and severity of CAD are major determinants of prognosis, and complete revascularization (CR) of all ischemia-causing lesions might improve outcomes. Several studies have shown better outcomes with CR than with incomplete revascularization, emphasizing the importance of functional angioplasty. However, different definitions of inducible myocardial ischemia have been used across studies, making their comparison difficult. Various diagnostic tools have been used to estimate the presence, extent, and severity of inducible myocardial ischemia. However, to date, there are no agreed reference standards of inducible myocardial ischemia. The hallmarks of inducible myocardial ischemia such as electrocardiographic changes and regional wall motion abnormalities may be more clinically relevant as the reference standard to define ischemia-causing lesions. In this review, we summarize studies regarding myocardial ischemia, PCI guidance, and possible explanations for similar findings across studies. Also, we provide some insights into the ideal definition of inducible myocardial ischemia and highlight the appropriate PCI strategy.

  • 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.

  • Restenosis remains a major limitation of percutaneous coronary interventions. Numerous studios including pharmacological approaches and new devices failed to reduce the restenosis rate except coronary stenting. Since the results of $BENESTENT^{1)}\;and\;STRESS^{2)}$ studies came out, coronary stenting has been the most popular interventional strategy in the various kinds of coronary stenotic lesions, although the efficacy of stenting was shown only in the discrete lesion of the large coronary artery. The widespread use of coronary stenting has improved the early and late outcomes after coronary intervention, but it has also led to a new and serious problem, e.g., in-stent restenosis. Intravascular radiation for prevention of restenosis is a new technology in the field of percutaneous coronary intervention. Recent animal experiments and human trials have demonstrated that local irradiation, in conjunction with coronary interventions, substantially diminished the rate of restenosis. This paper reviews basic radiation biology of intracoronary radiation and its role in the inhibition of restenosis. The current status of intracoronary radiation therapy using Re-188 liquid balloon is also discussed.

  • 본 연구는 관상동맥중재술을 받은 지역사회 거주 노인의 건강행위 이행에 영향을 미치는 심리사회적 요인을 분석하기 위해 수행된 서술적 조사연구이다. 경상남도 J시 G대학교병원에서 관상동맥중재술을 받고 외래를 내원한 환자 126명을 대상으로 2018년 7월 15일부터 10월 2일까지 구조화된 설문지를 사용하여 자료수집 후 SPSS/WIN 21.0으로 통계 분석하였다. 분석결과 대상자 특성에 따른 건강행위 이행은 배우자 유무, 교육수준, 주관적 건강상태, 주관적 삶 만족도에 따라 차이가 있었으며, 의료인 지지, 회복탄력성에서는 정적 상관관계가 있었고, 지각된 스트레스, 지각된 스트레스의 하위영역인 가족관계, 불안과 위축, 빈곤과 재정, 우울과는 부적 상관관계가 있었다. 다중회귀분석 결과 회복탄력성, 지각된 스트레스의 하위영역인 빈곤과 재정, 교육수준, 주관적 삶 만족도가 관상동맥중재술을 받은 노인의 건강행위 이행을 27.9% 설명하는 것으로 나타났다. 이러한 결과를 기반으로 관상동맥중재술을 받은 지역사회 거주 노인의 건강행위 이행을 향상시키기 위한 간호중재 프로그램 개발과 적용이 필요하다.

  • Background: Coronary angioplasty has been replacing coronary artery bypass grafting (CABG) because of the relative advantage in terms of recovery time and noninvasiveness of the procedure. Compared to other Organization for Economic Cooperation and Development (OECD) countries, Korea has experienced a rapid increase in coronary angioplasty volumes. Methods: We analyzed changes in procedure volumes of CABG and of percutaneous coronary intervention (PCI) from three sources: the OECD Health Data, the National Health Insurance Service (NHIS) surgery statistics, and the National Health Insurance claims data. Results: We found the ratio of procedure volume of PCI to that of CABG per 100,000 population was 19.12 in 2014, which was more than triple the OECD average of 5.92 for the same year. According to data from NHIS statistics, this ratio was an increase from 11.4 to 19.3 between 2006 and 2013. Conclusion: We found that Korea has a higher ratio of total procedure volumes of PCI with respect to CABG and also a more rapid increase of volumes of PCI than other countries. Prospective studies are required to determine whether this increase in absolute volumes of PCI is a natural response to a real medical need or representative of medical overuse.

  • 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.

  • ACC/AHA/SCAI Guideline recommends for administration dual antiplatelet therapy after drug-eluting stent (DES) to prevent restenosis and stent thrombosis in patients with percutaneous coronary intervention (PCI). Recently triple antiplatelet therapy including cilostazol is known to reduce restenosis and stent thrombosis significantly after DES implantation. However, there is lack of data providing the efficacy of triple antiplatelet therapy. The purpose of this study is to evaluate the clinical effects of the triple therapy after DES implantation compared with the dual therapy. This retrospective study collected data from medical charts of 251 patients who received DES implantation between Jul 2006 and Jun 2008. They received either dual antiplatelet therapy (N = 154 clopidogrel and aspirin; Dual group) or triple antiplatelet therapy (N = 97 cliostazol, clopidogrel and aspirin; Triple group). Major adverse cardiac event rates (MACE, included total death, myocardial infarction, target lesion revascularization) at 12 months, 24 months, stent thrombosis, rates of bleeding complications and adverse drug reactions were compared between these two groups. Compared with the dual group, the triple group had a similar incidence of the MACE rates at 24months (12.3% vs. 12.4%, p = 0.99). There is no difference in overall stent thrombosis between two groups (Dual group 2.6% vs. Triple group 4.1%, p = 0.5). Subgroup analysis showed that diabetic patients got more benefit in reducing MACE rates but, there is no statistical difference. Bleeding complications and adverse drug effects were not different significantly. As compared with dual antiplatelet therapy, triple antiplatelet therapy did not reduce the 12-months, 24-months MACE rates and stent thrombosis. Bleeding complications and adverse drug effects were not different.
