  • Purpose: The purpose of this study was to compare the cardiac knowledge and symptoms recognition between men and women with acute coronary syndrome (ACS). Methods: Cross-sectional survey research design and convenience sampling were used in this study. 64 men and 42 women from a university medical center were participated in this study. Data collection were used with self reported questionnaires and medical records. Results: There was no difference in cardiac knowledge by gender. Women marked the higher score in symptoms recognition than men. Significant gender differences were observed in the reports of several symptoms (headache, nausea, palpitation, hand paresthesia, and leg numbness) and with ACS. There was significant correlation between cardiac knowledge and symptom recognition on both men and women. Conclusion: These findings suggest that health care professionals should pay attention to the differences in clinical symptoms between women and men. Furthermore, tailored information about possible symptoms of coronary artery disease according to the patient's gender is needed.

  • Phlegmasia cerulea dolens (PCD) is one of the most critical disorders of acute deep vein thrombosis in that it can cause permanent disability secondary to the compartment syndrome. Although several etiological factors have been proposed, PCD after coronary artery bypass surgery is extremely rare and its definitive pathophysiology is still under debate. We herein present a case of PCD that resulted in the compartment syndrome after coronary artery bypass surgery. Early recognition and decompression of PCD are crucial for saving the affected limbs.

  • Coronary artery ectasia (CAE) is defined as the dilation of a segment of a coronary vessel to at least 1.5 times the diameter of its normal adjacent segment. Mean platelet volume (MPV) plays a role in acute coronary syndromes, with high MPV correlating to poor prognosis for acute thrombotic events and CAE. Several studies investigated the relationship between MPV and CAE, resulting in conflicting results. These results led us to systematically review all studies investigating the relationship between MPV and ectatic heart diseases by performing a meta-analysis study in order to report a unified result. This meta-analysis study investigated all case-control articles examining the relationship between MPV and CAE. All studies in the following databases published until January 31, 2018, were investigated: Science Direct, Scopus, PubMed, Google Scholar, and Web of Science. Following a quality control evaluation, 14 articles, all of which were published following studies performed in Turkey from 2007 to 2016, met the criteria for study inclusion. After pooling the results from all of the articles, a total standardized mean difference (SMD) value of 0.584 (95% CI, 0.219, 0.95) was obtained using the D+L pooled SMD, indicating a significant difference (P=0.002) between the two groups, with higher MPV values in ectatic patients when comparing to healthy individuals. Therefore, increased MPV levels were significantly related to CAE, suggesting that platelets, with their inflammatory and thrombotic activities, play a role in this disease. Therefore, anti-platelet and anti-inflammatory therapies may be effective in treating CAE.

  • The purposes of the present study are to investigate hemodynamic characteristics and to define shear-sensitive remodeling in the stenosed coronary models. Two models for the compensatory remodelling used for this research are a pre-stenotic dilation and a post-stenotic dilation models for the computer simulation. The peak wall shear stress on the post-stenotic model is higher than that of the pre-stenotic model. Two recirculation zones are generated in the pre-stenotic model, and the zones in the pre-stenotic model are smaller than those in the post-stenotic model. Variation of the wall shear stress in the pre-stenotic model is lower than that in the post-stenotic model. In computer simulation with the post-stenotic model, higher temporal and spatial shear fluctuation and stress suggested shear-sensitive remodeling. Shear-sensitive remodeling may be associated with the increased risk of plaque rupture, the underlying cause of acute coronary syndromes, and sudden cardiac death.

  • 관상동맥질환의 임상적인 개념은 지난 10년 동안 패러다임의 변화를 보여왔다. 관상동맥질환은 대부분 진행성 질환이며, 관상동맥질환 환자는 질병 진행의 어느 시점에서도 급성 관상동맥 증후군에 직면할 수 있다. 이러한 임상적 맥락에서 2019년 유럽심장학회 가이드라인에서는 조기 진단과 꾸준한 관리가 필요한 관상동맥질환의 임상적인 중요성을 반영하여 "만성관상동맥증후군"이라는 용어의 사용을 발표하였다. 최근 관상동맥 전산화단층촬영 혈관조영술을 이용한 관상동맥질환의 평가는 많은 발전을 이루었고, 안정형 협심증 또는 만성 관상동맥증후군 환자에서 관상동맥 전산화단층촬영 혈관조영술의 임상적 유용성은 초기 무증상 관상동맥질환의 발견에서부터 죽상경화판의 특성 분석 및 관상동맥질환의 치료 전략 결정에 도움을 주는 역할까지 관상동맥질환의 다양한 단계에 걸쳐 입증되고 있다. 이 종설에서는 안정형 협심증 환자의 이해를 돕는 병태생리를 설명하고 이에 대한 관상동맥 전산화단층촬영의 임상적 적용과 역할에 대해 알아보고자 한다.

  • Current therapy of aortic dissections remains unstandardized because of the relative rarity of these catastrophic events and conflicting reported results of various therapeutic strategies. Hence, we reviewed our current results and planned to purify our method of interpretation of results and so, to standardize therapeutic managements. This study comprised unselected, consecutive 27 patients with aortic dissections who were operated at Seoul National University Hospital from Jan 1983 to March 1988. The results from analysis of their preoperative, operative and postoperative finding were as follows: 1] 7 patients had acute type A, 14 had chronic type A, 4 had acute type B, and 2 had chronic type B. 2] The causes of dissections were unclear, but 8 patients had Marfan`s syndromes, 2 had previous operative histories on cardiovascular systems and 2 had congenital heart diseases. 3] Multiple preoperative variables were found to correlate significantly with operative mortality and complications. The prevalences of such preoperative major complicating factors were significantly more frequent in acute than chronic [P < 0.05] and type A than type B [P < 0.01]. 4] Operations were performed according to the type of the dissections and whether it was acute or chronic. Usually dacron tube graft replacements were performed[25/26]. Intraluminal sutureless graft replacement was performed in 11 patients. Of the 14 patients with combined aortic regurgitation, concomitant aortic valve resuspension in 4, seperative aortic valve replacement in 1, and aortic valve replacement with coronary reimplantation were performed in 9 patients. 2 patients had concomitant arch vessel managements. 5] Over-all operative mortality rate was 33% and 54% for acute type A, 25% for acute type B, 29% for chronic type A, 0% for chronic type B respectively. The main causes of operative mortality were cardiovascular complications [mainly CPB-weaning failure] in acute cases and hemorrhagic complications in chronic cases.

  • Objectives: The association between obstructive sleep apnea (OSA) and mortality or serious cardiovascular events over a long period of time is not clearly understood. The aim of this observational study was to estimate the clinical effectiveness of continuous positive airway pressure (CPAP) treatment on an outcome variable combining mortality, acute myocardial infarction (AMI), and cerebrovascular insult (CVI) during a follow-up period of 15.5 years ($186{\pm}58$ months). Methods: The data set consisted of 978 patients with an apnea-hypopnea index (AHI) ${\geq}5.0$. One-third had used CPAP treatment. For the first time, a data-driven causal Bayesian network (DDBN) and a hypothesis-driven causal Bayesian network (HDBN) were used to investigate the effectiveness of CPAP. Results: In the DDBN, coronary heart disease (CHD), congestive heart failure (CHF), and diuretic use were directly associated with the outcome variable. Sleep apnea parameters and CPAP treatment had no direct association with the outcome variable. In the HDBN, CPAP treatment showed an average improvement of 5.3 percentage points in the outcome. The greatest improvement was seen in patients aged ${\leq}55$ years. The effect of CPAP treatment was weaker in older patients (>55 years) and in patients with CHD. In CHF patients, CPAP treatment was associated with an increased risk of mortality, AMI, or CVI. Conclusions: The effectiveness of CPAP is modest in younger patients. Long-term effectiveness is limited in older patients and in patients with heart disease (CHD or CHF).
