    ABSTRACT: Purpose The aim of this study is to investigate the association between short sleep hour and body mass index (BMI) obesity after adjustment for socioeconomic position and health behavior factors in the general representative population in Korea in 2007-2009. Methods The fourth Korea National Health and Nutrition Examination Survey was conducted by the Korea Institute for Health and Social Affairs for the Korean Ministry of Health and Welfare in 2007-2009. The sample included 6,424 Korean Young adults aged 20-44 years (male 3,400 and female 3,017). Sleep duration was grouped by hours slept but was also classified into two categories: short sleepers (<6 h/night) and normal sleepers (6–9 h/night). Results The distribution of short sleepers and normal sleepers was 9.5% and 90.5%, respectively. The distribution of obesity was 27.8%. The adjusted odds ratio (OR) for obesity was 1.39 (95% Confidence Interval (CI) 1.09-1.77) after adjustment for confounding factors. In male, the adjusted OR for obesity was not significant difference, however, in female, the adjusted OR for obesity was 1.66 (95% CI 1.14-2.40) Conclusions This community-based random sample drawn from the entire Korean young adults population showed that short sleep hour was significantly associated with obesity, especially, female.

    ABSTRACT: Purpose The aim of this study is to examine the prevalence of chronic kidney disease (CKD) in metabolic syndrome (MetS) and to investigate the association between metabolic syndrome (MetS)and chronic kidney disease (CKD) after adjustment for socioeconomic position and health behavior factors in the general representative population in Korea in 1998 through 2009. Methods The first, second, third and fourth Korea National Health and Nutrition Examination Survey (KNHANES I, II, III, and IV) was conducted by the Korea Institute for Health and Social Affairs for the Korean Ministry of Health and Welfare in 1998, 2001, 2005 and 2007-2009. The sample included 11,289 Korean men and women aged 45-64 years. Subjects were classified into two groups based on their baseline glomerular filtration rate (GFR) using the Chronic Kidney Disease Epidemiology Collaboration equation: 1) greater than or equal to 60 mL/min/1.73 m2 (non-CKD group; normal and mild renal dysfunction), and 2) less than 60 mL/min/1.73 m2 (CKD group; moderate, severe renal dysfunction, and renal failure). The MS was determined using National Cholesterol Education Program Adult Treatment Panel III criteria and the Asia-Pacific criteria for obesity based on waist circumference. Results The distribution of CKD was 1.8%, 6.8%, 3.6% and 2.9% in 1998, 2001, 2005, and 2007-2009, respectively. The distribution of MetS was 41.4%, 41.9%, 39.7% and 34.3%, respectively. The adjusted odds ratio for MS was 6.26 (95% Confidence Interval (CI) 1.78-21.9), 2.96 (95% CI 1.02-8.54), 2.55 (95% CI 0.50-13.0), and 1.89 (95% CI 1.19-3.02) after adjustment for confounding factors, respectively. Conclusions This community-based random sample drawn from the entire Korean middle aged population showed that MS was significantly associated with CKD.

    ABSTRACT: Hereditary protein S deficiency is one of the natural anticoagulant deficiency causing thrombophilia. Protein S deficiency is caused by a mutation in the PROS1 gene on 3q11.2 and is typically inherited in an autosomal dominant manner. We herein describe a Korean man with protein S deficiency from a novel nonsense mutation of PROS1. The patient was a 47-year-old man with deep-vein thrombosis. No relevant family history was documented. Coagulation test results included a significantly decreased protein S activity at 30%. Molecular genetic analysis targeting PROS1 on suspicion of hereditary protein S deficiency revealed that he was heterozygous for a novel transversion mutation, c.903C>G, in the exon 9 of PROS1. The mutation was predicted to result in premature termination at the codon 301 in the laminin G-type domain (p.Tyr301) of the protein (nonsense mutation). According to a review of the literature and database, the mutation described herein is the first substitution mutation affecting the codon 301 of PROS1.

    ABSTRACT: Hereditary protein S deficiency from a mutation in the PROS1 gene causes a genetic predisposition to develop venous thromboembolic disorders in humans. Recently, the acknowledgment of the clinical significance of large copy number mutations in protein S deficiency has increased. In this study, the authors investigated the genomic architecture of PROS1 in order to understand the microscopic sequence environment leading to large intragenic copy number mutations in the gene. The study subjects were 3 unrelated male patients with hereditary protein S deficiency from a tandem duplication mutation involving exons 5-10 of PROS1. Breakpoint analyses revealed 10-bp microhomology sequences in the intervening sequence (IVS)-4 and IVS-10 at the duplication junction without additional sequence changes, suggesting a single replication-based event as the potential molecular mechanism of rearrangement and founder effect in the mutant alleles. Further analyses on nucleotide sequences flanking the microhomology sequence revealed the presence of a repeat element (LTR-ERV1) and quadruplex-forming G-rich sequences in IVS-4. The results from genotyping multi-allelic short tandem repeats supported founder effect in the identical mutations in the 3 unrelated patients. In conclusion, we identified unique genomic architectures in the intervening sequences of PROS1 that underlie a large intragenic tandem duplication mutation leading to inherited thrombophilia.

    ABSTRACT: The aim of this study was to determine the normal value of brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group, gender, and the presence of cardiovascular risk factors in healthy Koreans, and to investigate the association between PWV and risk factors such as prehypertension, dyslipidemia, smoking, and obesity. We measured an arterial stiffness in 110 normal subjects who were 20 to 69 yr-old with no evidence of cardiovascular disease, cerebrovascular accident or diabetes mellitus. The mean values of baPWV and cfPWV were 12.6 (±2.27) m/sec (13.1±1.85 in men, 12.1±2.51 in women; P=0.019) and 8.70 (±1.99) m/sec (9.34±2.13 in men, 8.15±1.69 in women; P=0.001), respectively. The distribution of baPWV (P<0.001) and cfPWV (P=0.006) by age group and gender showed an increase in the mean value with age. Men had higher baPWV and cfPWV than women (P<0.001). There was a difference in baPWV and cfPWV by age group on prehypertension, dyslipidemia, current smoking, or obesity (P<0.001). In multiple linear regression, age and prehypertension were highly associated with baPWV and cfPWV after adjustment for confounding factors (P<0.001). The present study showed that baPWV and cfPWV are associated with age, gender, and prehypertension in healthy Koreans.

    ABSTRACT: Malperfusion syndrome caused by acute type A aortic dissection is associated with high mortality. However, the impact of subclinical malperfusion is not clear. We reviewed surgical outcomes in acute type A dissection for the presence of clinical and subclinical malperfusion. From 1998 to 2012 at Samsung Medical Center, 268 consecutive patients had an emergency operation for acute type A dissection. We divided patients into three groups: clinical, subclinical, and no malperfusion. Clinical malperfusion was identified by signs or symptoms of organ dysfunction (n = 36). Subclinical malperfusion was defined as laboratory evidence of organ hypoperfusion or imaging findings without signs or symptoms (n = 40). Patients with no evidence of malperfusion were defined as having no malperfusion (n = 192). The mean patient age was 57.3 ± 13.8 years, and 141 patients (53%) were women. Antegrade selective cerebral perfusion was used in 213 patients (79%). Total arch replacement was performed in 53 patients (20%). The average cardiopulmonary bypass time was 218.31 ± 72.17 minutes. Early mortality was 8% in all patients, 5% in the no-malperfusion group, 8% in the subclinical malperfusion group, and 25% in the clinical malperfusion group. Overall survival in the clinical malperfusion group was worse than in the subclinical (p = 0.026) and no-malperfusion (p < 0.001) groups. Survival rates in the subclinical and no-malperfusion groups were not different (p = 0.482). On multivariate Cox regression analysis, older age, longer cardiopulmonary bypass time, and clinical malperfusion syndrome were predictors of mortality. Mortality was not increased in asymptomatic patients with malperfusion by laboratory or imaging findings. Immediate operation before progression of organ malperfusion is still a valid option for patients with acute type A dissection.

    ABSTRACT: The aim of this study is to assess the changes in the causes of valvular heart disease between 2006 and 2011 in Korea. Data were collected from the Korean National Health Insurance Service from 2006 through 2011. These data consisted of primary diagnoses related to valvular heart disease regardless of other conditions. Valvular heart disease included non-rheumatic mitral valve disorders, non-rheumatic aortic valve disorders, rheumatic mitral valve disorders, and rheumatic aortic valve disorders. Overall, the age-standardized cumulative prevalence of non-rheumatic valvular heart disease was 70.6 per 100,000 persons in 2006 and 110.3 in 2011. This represented an increase from 42.2 to 65.2 in women and from 28.4 to 45.1 in men. In particular, there was a greater increase in prevalence in patients aged 65years or older compared with groups aged 20-44years or 45-64years for both genders. The age-standardized cumulative prevalence of rheumatic valve disease did not change dramatically between 2006 and 2011. The overall age-standardized cumulative prevalence of non-rheumatic valvular heart diseases increased between 2006 and 2011, especially in individuals older than 65years. These changes should be considered in future designs of cardiovascular healthcare services in countries with a rapidly aging population.

    ABSTRACT: Cardiac arrest caused by acute pulmonary embolism is associated with high patient mortality. We reviewed patients who had cardiac arrest by acute pulmonary embolism. Between January 2001 and September 2013 we identified 20 patients at our institution with a confirmative diagnosis of acute pulmonary thromboembolism and cardiac arrest. Percutaneous cardiopulmonary support (PCPS) and surgical embolectomy is the standard course of care for patients in shock or cardiac arrest due to pulmonary thromboembolism at our institution. Patients were divided into two groups (PCPS group, No PCPS group). PCPS was used in 60%. Surgical embolectomy was performed for 85%. Overall in-hospital and surgical mortalities were 35% and 29%, respectively. Based on multivariate analysis, both cardiopulmonary resuscitation > 15 minutes and absence of PCPS were significant risk factors affecting survival (p = 0.001 and 0.049, respectively). When the duration of cardiac arrest is short, surgical embolectomy is a viable option after cardiac arrest due to pulmonary thromboembolism. PCPS may be a useful tool for both patient stabilization and providing a bridge when deciding upon further management options.

    ABSTRACT: To determine bispectral index (BIS) values produced by equipotent concentrations of commonly used volatile anaesthetics. Female patients undergoing thyroidectomy were randomly assigned to receive isoflurane, sevoflurane or desflurane anaesthesia. After induction, anaesthesia was maintained by the volatile agent at 1 minimum alveolar concentration and supplemented with remifentanil infusion. BIS values were recorded during 1 h surgical anaesthesia after a 15 min equilibrium phase. Time-averaged BIS value during the study period was significantly lower in the desflurane group (n = 29) than the sevoflurane group (n = 27) (37.0 ± 4.9 vs 41.5 ± 5.9). Duration of deep hypnosis (BIS < 40) was significantly longer in the desflurane group than the sevoflurane group (40.2 ± 20.7 vs 24.3 ± 22.5 min). There were no significant differences in any parameter between the isoflurane group (n = 27) and any other group. Desflurane produces a greater hypnotic effect than sevoflurane during equipotent anaesthesia. Management of volatile anaesthesia using predetermined minimum alveolar concentration targets can lead to an unnecessarily long duration of deep hypnosis.

    ABSTRACT: To determine the role of endothelial progenitor cells (EPCs) in the pathogenesis of thromboangiitis obliterans (TAO), EPC numbers and colony-forming units, migratory function and tubular structure formation in vitro were compared between 13 young male TAO patients and two age-matched healthy control groups: 11 smokers and 12 non-smokers. TAO patients had significantly lower numbers of EPCs and EPC colonies compared to both non-smokers [190 (97.0-229) vs 528 (380-556), p < 0.001 for EPCs and 0.80 (0.53-1.00) vs 2.80 (2.08-4.00) per mm(2), p = 0.001 for EPC colonies] and smokers [190 (97.0-229) vs 272 (229-326), p = 0.012 for EPCs and 0.80 (0.53-1.00) vs 2.80 (1.80-3.93) per mm(2), p = 0.001 for EPC colonies]. However, there were no significant differences in migratory function or tube formation between the three groups. These results suggest that TAO patients have an intrinsic decrease in EPCs not entirely associated with smoking, which may be the cause of endothelial dysfunction seen in TAO patients leading to the development of this disease at early ages.

    ABSTRACT: The cardiovascular system may be one of the target organs of both immunoglobulin G4 related and non-related systemic multifocal fibrosclerosis. We present a case of IgG4 non-related systemic multifocal fibrosclerosis mimicking mitral stenosis on echocardiography. For a more detailed differential diagnosis, we used multimodal imaging techniques. After surgical biopsy around the abdominal aortic area in the retroperitoneum, histological examination revealed IgG4 non-related systemic multifocal fibrosclerosis. We describe the multimodal imaging used to diagnose IgG4 non-related systemic multifocal fibrosclerosis and a positive response to steroid treatment. There have been no previous case reports of IgG4 non-related systemic multifocal fibrosclerosis with intracardiac involvement. Here, we report a case of IgG4 non-related systemic multifocal fibrosclerosis mimicking mitral stenosis.

    ABSTRACT: The objective of this study is to analyze long-term survival of the subjects with aortic aneurysm (AA). The sample included 294 Korean patients aged ≥30 years who were hospitalized from 1994 through 2004. 294 AA subjects (54 in affected coronary artery disease (CAD) and 240 in non-CAD; 223 in AA including abdominal only (AAA) and 71 in AA including thoracic (TAA)) had confirmed by computed tomography angiography in Cardiac & Vascular Center, Samsung Medical Center. Mortality data were obtained from all participants between 1994 and 2009 from the Statistics Korea. All-cause mortality was measured at 5 to15 years. The mean age (years) of AA in CAD subjects was 68.7 (6.4) and that of AA in non-CAD subjects was 66.5 (11.3) (p=NS). During the 5 to 15 years follow-up, all-cause cumulative mortality rate was 12.9% in CAD and 15.8% in non-CAD (Fig A). All-cause cumulative mortality rate by AA affected site was 18.3% in TAA and 14.4% in AAA (Fig B). The mean survival time was 6.18 (0.16) years in CAD and 7.40 (0.12) years in non-CAD. The mean survival time by AA affected site was 7.92 (3.32) years in TAA and 7.90 (3.15) years in AAA. The independent predictors of mortality were included, but not limited to, age, smoking and AA affected site. In this study, we found that cardiovascular risk factors contributed to mortality. And, it seems that there is similarity between CAD and non-CAD in AA, and between TAA and AAA by AA affected site for their mortality rate.

    ABSTRACT: Hereditary natural anticoagulant deficiencies are the major cause of genetic thrombophilia in Asia. Given the growing acknowledgment of the risk of venous thromboembolism in Asian populations, we investigated the frequency and mutation spectrums of natural anticoagulant deficiency in Korea. The patient group consisted of consecutive patients with venous thromboembolism screened for thrombophilia. Genetic tests were performed on suspicion of natural anticoagulant deficiency. For the population group, >3,000 were screened from routine check-up, and those with a decreased level (<1-percentile) of natural anticoagulant underwent genetic tests. Mutations were detected by direct sequencing of PROC, PROS1, and SERPINC1, followed by additional multiplex ligation-dependent probe amplification for PROS1 and SERPINC1 for dosage mutations. Total 127 among 500 patients screened were suspected to have natural anticoagulant deficiency, and 71 were genetically confirmed: protein C deficiency in 36 (50.7%), antithrombin deficiency in 21 (29.6%), and protein S deficiency in 14 (19.7%). Total 3,129 individuals were screened from population, and the frequency of natural anticoagulant deficiency was ~1.0%: antithrombin deficiency 0.49%, protein C deficiency 0.35%, and protein S deficiency 0.16%. Two PROC mutations causing type I protein C deficiency were prevalent (Arg211Trp and Met406Ile in patients and Arg211Trp in population). Two SERPINC1 mutations causing type II antithrombin deficiency, Arg79Cys and Ser158Pro, were prevalent in the population group. This is the first study on the genetic epidemiology of natural anticoagulant deficiencies in Korea. The results demonstrated distinct frequencies and mutation spectrums underlying genetic thrombophilia in Korea in comparison with not only Caucasian but also other Asian populations.

    ABSTRACT: Purpose:To evaluate coronary arterial lesions and to assess their correlation with clinical findings in patients with Takayasu arteritis (TA) by using coronary computed tomographic (CT) angiography.Materials and Methods:This retrospective study was approved by the hospital internal review board, and informed consent was waived. A total of 111 consecutive patients with TA (97 female, 14 male; mean age, 44 years ± 13.8 [standard deviation]; age range, 14-74 years) underwent CT angiography of the coronary arteries and aorta with 128-section dual-source CT. CT angiographic, clinical, and laboratory findings of each patient were retrospectively reviewed. Statistical differences between coronary CT angiographic findings and clinical parameters were examined with univariate analysis.Results:Of 111 patients, 32 (28.8%) had cardiac symptoms and the remaining 79 (71.2%) had no cardiac symptoms. Fifty-nine patients (53.2%) had coronary arterial lesions at coronary CT angiography. Three main radiologic features were detected: coronary ostial stenosis (n = 31, 28.0%), nonostial coronary arterial stenosis (n = 41, 36.9%), and coronary aneurysm (n = 9, 8.1%). Coronary artery ostial or luminal stenosis of 50% or more or coronary aneurysms were observed in 26 (23.4%) patients with TA. Patients with coronary arterial abnormalities at coronary CT angiography had higher incidences of hypertension (P = .02), were older at the time of CT (P = .01), and had longer duration of TA (P = .02) than those without coronary artery abnormalities. The presence of cardiac symptoms, disease activity, and other comorbidities was not associated with differences in coronary artery involvement.Conclusion:In patients with TA, there is a high prevalence of coronary arterial abnormalities at coronary CT angiography, regardless of disease activity or symptoms. Thus, coronary CT angiography may add information on coronary artery lesions in patients with TA.© RSNA, 2013.

    ABSTRACT: Aortic root size is an important parameter in vascular diseases and can be easily assessed by transthoracic echocardiography. However, measurements values may vary according to cardiac cycle and the definition used for edge. This study aimed to define normal values according to the measurement method specified by two different guidelines to determine the influence of the different methods on echocardiographic measurements. Healthy Korean adults were enrolled. The aortic root diameters were measured twice at four levels (aortic annulus, sinuses of Valsalva, sinotubular junction, and ascending aorta) by the 2005 American Society of Echocardiography (ASE) guidelines (measured from leading edge to leading edge during diastole) and the 2010 ASE pediatric guidelines (measured from inner edge to inner edge during systole). One hundred twelve subjects aged 20--69 years were enrolled. The aortic diameters (cm) determine by the aforementioned two guidelines showed significant difference. Measurements were larger in 2005 ASE guideline at aortic annuls, sinuses of Valsalva, and sinotubular junction level, but smaller at ascending aortic level with 2-3mm of differences. Intraobserver variability was similarly good, but interobserver variability was slightly higher than intraobserver variability in both measurement methods. BSA and age was most important determinant for aortic root size. The measurement method of aortic root can affect the echocardiographic result. The measurement method should be noted when assessing clinical significance of aortic root measurement.

    ABSTRACT: To identify predictors of postoperative pulmonary complications (PPCs) in patients aged ≥60 years who underwent laparoscopy-assisted gastrectomy (LAG), and to examine the value of preoperative spirometry to predict PPCs. Patients with preoperative spirometric results who underwent LAG were retrospectively studied. Spirometry included four parameters: forced expiratory volume in 1 s; functional vital capacity; mean forced expiratory flow during middle of functional vital capacity; peak expiratory flow rate. Of 213 patients, overall incidence of PPCs was 19.2%. Abnormal spirometry findings were not identified as an independent predictor of PPCs using multivariate logistic regression analysis. Age was found to be the only independent predictor of PPCs out of all variables evaluated. Separate assessment of individual spirometric parameters using receiver-operating curve analyses indicated poor diagnostic accuracy. Preoperative spirometry was not reliably predictive of PPCs, either as combined or individual parameters, in patients aged ≥60 years who underwent LAG. These results do not support routine use of spirometry to stratify risk of PPCs in this surgical population.

    ABSTRACT: To retrospectively evaluate and compare the long term patency and antihypertensive effect of angioplasty and stent insertion in renal artery stenosis caused by Takayasu arteritis, with CT angiography and clinical follow-up. We retrospectively analyzed and compared effects on hypertension and patency of renal artery in 16 patients (age ranging from 16 to 58 years, mean: 32.1 years) with renovascular hypertension caused by Takayasu arteritis who underwent endovascular treatment including angioplasty (n=13) and stent placement (n=9) for 22 stenotic renal arteries. Technical success was 95% (21/22) without major complications. In the last follow-up CT angiogram (mean 85±41 months), restenosis was 8% (1/12) in angioplasty and 66% (6/9) in stent. Patency rates of angioplasty were 100%, 91.7%, 91.7% and primary unassisted and primary assisted patency rates of stent placement were 55.6%, 33.3%, 33.3% and 88.9%, 66.7%, 55.6% at 1-, 3- and 5-years, respectively. In clinical follow-up (mean 120±37.8 months, range 48-183 months), beneficial effects on hypertension were obtained in 87% of patients (13/15) and there was no significant difference between the patients who were treated by only angioplasty and the patients who received stent placement in at least one renal artery, regardless of whether or not angioplasty had been performed in the other renal artery. Compared with stent placement, angioplasty demonstrated better long term patency and similar clinical benefit on renovascular hypertension in renal artery stenosis of Takayasu arteritis. We suggest that stent placement should be reserved for obvious angioplasty failure.

    ABSTRACT: Among the parameters for surveillance of patients at risk of acute type A aortic dissection, the aortic size has been considered a cardinal factor. Preventive surgery of the aorta in asymptomatic patients on the basis of size alone is still controversial in patient populations lacking other risk factors for aortic dissection. The aim of the present study was to assess the value of the aortic diameter as a current criterion for elective aortic surgery to prevent the development of aortic dissection in patients without and with Marfan syndrome (MFS). We reviewed the data from patients diagnosed with acute type A aortic dissection from December 1994 to March 2009 at our institute. A total of 237 patients who presented with acute type A aortic dissection were enrolled, of whom 31 were diagnosed with MFS. The maximal ascending aorta size was 46.7 mm (range, 42.9-51.6) in non-MFS patients and 58.5 mm (range, 43.8-64.9) in MFS patients (P < .001). Two thirds (74%) of the MFS patients had a maximal aortic root size of ≥45 mm. However, 87% of the 206 non-MFS patients had an aortic diameter <55 mm. Non-MFS patients presenting with an aortic size <55 mm developed aortic dissection at a younger age and had a higher body mass index than those with an aortic size ≥55 mm. Type A aortic dissection occurs in smaller aortas in non-MFS patients compared with those with MFS.
