Cardiac disease is the class of diseases related to the heart that plays an important role in supplying blood to our body and the number of deaths is increasing every year. Cardiac Rehabilitation has been conducted as treatment and prevention in such patients with cardiac disease. Cardiac rehabilitation programs in general contain pat~ient education and consulting service in order to improve physical strength in patients with cardiac disease, decrease cardiac symptoms, promote fitness, and minimize the risk of following cardiac problems including cardiac arrest. Among them therapeutic exercise is the mainstream of cardiac rehabilitation, however, to accomplish more efficient patient care, standardized guideline based on each disease and researches from a physical therapy perspective are required.

본 연구는 cardiac CT를 이용한 박출계수 산출 시 cardiac MRI와 물리적 시간 해상도 차이를 분석하여 보정함으로써 cardiac CT의 오진율을 감소시키고자 하였다. 연구 방법은 대동맥판막 역류 질환을 진단받은 138명을 대상으로 cardiac CT와 cardiac MRI의 박출계수를 산출한 후 두 검사 간 물리적 시간 해상도 차이를 cardiac CT의 박출계수에 보정한 다음 신뢰도를 평가하여, 물리적 시간 해상도 차이 보정 전, 후 cardiac CT의 오진율이 개선됐는지 평가 하였다. 연구결과, 물리적 시간 해상도 차이 보정 전 cardiac CT 박출계수의 오진율은 38.4%(53명)로 높게 나왔고, 보정 후 오진율은 23.9%(33명)로 감소하였다. 또한 Bland-Altman plot에서 확인한 보정된 cardiac CT 박출계수는 cardiac MRI의 박출계수와의 일치도가 상당히 높은 것을 알 수 있다. 결론적으로 심장판막 질환 진단시 단순한 cardiac CT의 박출계수로만 진단하는 것은 오진율을 높일 수 있으므로 cardiac MRI로 물리적 시간 해상도의 차이를 보정하면 오진율을 14.5%(20명) 감소시킬 수 있다. 그러므로 본 연구를 박출계수 산출 시 적용한다면 유용성이 높다고 사료된다.

Purpose: Cardiac arrest has multiple characteristics that need to be approached as an integrated method according to the various changes in the body system. This study was performed to develop a useful guideline for early detection of cardiac arrest by revealing the attributes of cardiac arrest through a concept analysis. Methods: This study was conducted according to the Walker and Avant's concept analysis method. Systematic literature review and in-depth interview with nurses who experienced cardiac arrest situation were conducted. Based on the literature reviews and in-depth interviews with nurses, the attributes and the empirical referents of the concept of cardiac arrest were elicited. Results: The definable attributes of cardiac arrest were 1) loss of consciousness, 2) abnormal respiratory condition, 3) abnormal cardiovascular signs. Cardiac arrest was found to occur by several antecedents such as cardiac problem, non-cardiac problem, or general problem, whereas ischemia and re-perfusion injury, which can lead to multiple organ failure and death, were derived as consequences. Conclusion: In this study, the concept analysis eliciting attributes and empirical referents is found to be useful as a guideline for understanding and managing cardiac arrest. Based on these findings, clinical providers are expected to make a precise and rapid decision on cardiac arrest and respond quickly, which may increase survival rate of the patients underwent the arrest event.

Cardiomyocyte differentiation occurs through complex and finely regulated processes including cardiac lineage commitment and maturation from pluripotent stem cells (PSCs). To gain some insight into the genome-wide characteristics of cardiac lineage commitment, we performed transcriptome analysis on both mouse embryonic stem cells (mESCs) and human induced PSCs (hiPSCs) at specific stages of cardiomyocyte differentiation. Specifically, the gene expression profiles and the protein-protein interaction networks of the mESC-derived platelet-derived growth factor receptor-alpha (PDGFRα)⁺ cardiac lineage-committed cells (CLCs) and hiPSC-derived kinase insert domain receptor (KDR)⁺ and PDGFRα⁺ cardiac progenitor cells (CPCs) at cardiac lineage commitment were compared with those of mesodermal cells and differentiated cardiomyocytes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses revealed that the genes significantly upregulated at cardiac lineage commitment were associated with responses to organic substances and external stimuli, extracellular and myocardial contractile components, receptor binding, gated channel activity, PI3K-AKT signaling, and cardiac hypertrophy and dilation pathways. Protein-protein interaction network analysis revealed that the expression levels of genes that regulate cardiac maturation, heart contraction, and calcium handling showed a consistent increase during cardiac differentiation; however, the expression levels of genes that regulate cell differentiation and multicellular organism development decreased at the cardiac maturation stage following lineage commitment. Additionally, we identified for the first time the protein-protein interaction network connecting cardiac development, the immune system, and metabolism during cardiac lineage commitment in both mESC-derived PDGFRα⁺ CLCs and hiPSC-derived KDR⁺PDGFRα⁺ CPCs. These findings shed light on the regulation of cardiac lineage commitment and the pathogenesis of cardiometabolic diseases.

Simultaneous myofibril and mitochondrial development is crucial for the cardiac differentiation of pluripotent stem cells (PSCs). Specifically, mitochondrial energy metabolism (MEM) development in cardiomyocytes is essential for the beating function. Although previous studies have reported that MEM is correlated with cardiac differentiation, the process and timing of MEM regulation for cardiac differentiation remain poorly understood. Here, we performed transcriptome analysis of cells at specific stages of cardiac differentiation from mouse embryonic stem cells (mESCs) and human induced PSCs (hiPSCs). We selected MEM genes strongly upregulated at cardiac lineage commitment and in a time-dependent manner during cardiac maturation and identified the protein-protein interaction networks. Notably, MEM proteins were found to interact closely with cardiac maturation-related proteins rather than with cardiac lineage commitment-related proteins. Furthermore, MEM proteins were found to primarily interact with cardiac muscle contractile proteins rather than with cardiac transcription factors. We identified several candidate MEM regulatory genes involved in cardiac lineage commitment (Cck, Bdnf, Fabp4, Cebpα, and Cdkn2a in mESC-derived cells, and CCK and NOS3 in hiPSC-derived cells) and cardiac maturation (Ppargc1α, Pgam2, Cox6a2, and Fabp3 in mESC-derived cells, and PGAM2 and SLC25A4 in hiPSC-derived cells). Therefore, our findings show the importance of MEM in cardiac maturation.

목 적 : 수술 중, 후의 심근 손상은 선천성 심질환에 대한 개심술 후 심장 기능 부전의 주원인이다. 이 연구에서는 심근 세포에서만 발견되는 cardiac troponinI를 측정함으로서 수술 중, 후 심근 손상 정도와 회복 여부를 반영할 생화학적 표지자로서의 가치를 확인하고자 하였다. 방 법: 2001년 4월부터 7월까지 선천성 심질환으로 진단받고 개심술을 위해 본원에 입원한 환아 34명을 대상으로 하였다. Cardiac troponin I 치의 측정을 위해 술전 24시간 이내, 술후 1, 2, 3, 7일째에 각각 채혈을 시행했고, CPB 시간, ACC 시간, 기도 삽관시간, 수술 후 입원 기간을 측정하였다. 결 과 : Cardiac troponin I 치는 수술 후 1일째가 수술 전에 비해 유의한 증가가 있었고, 2, 3, 7일째에는 점차적으로 유의한 감소를 보였다. 심질환 별로는 수술 후 1일째 대혈관 전위에서 cardiac troponin I 치가 가장 높았고, 활로씨 4징, 방실중격결손, 심실중격결손, 심방중격결손 순으로 높은 치를 나타내었다. 심장폐 우회술 시간이 길수록, ACC 시간이 길수록 수술 후 1일째 cardiac troponin I 농도가 높았고, cardiac troponin I 농도가 높을수록 기도삽관 시간이 길었으나 입원 기간과는 상관관계가 없었다. 결 론: 개심술 후 시간에 따라, 개심술을 시행한 심질환에 따라 cardiac troponin I 농도의 의미 있는 증가와 점차적인 감소를 보임으로써 cardiac troponinI는 개심술 후 심근 손상의 정도 및 심근 손상에서의 회복 여부를 반영하는 생화학적 표지자로 가치가 있을 것으로 생각된다.
