OBJECTIVETo study the concurrence of congenital heart disease and hypospadias and the relationship between the two diseases.

METHODSWe investigated the incidence and types of congenital heart disease accompanied by hypospadias in male children received in our hospital from January 2002 to December 2012, compared them with those in the general population, and analyzed the correlation of different types of heart disease with the incidence rate of hypospadias.

RESULTSOf the 7 385 male children with congenital heart disease, 134 (1.81%) were found with hypospadias, with a significantly higher morbidity than in the general population (0.33% -0.40%) (P < 0.01). The incidence rates of hypospadias were significantly higher in the groups of ventricular septal defect (65/3 275, 1.98%), Fallot's tetralogy (17/770, 2.21%), macroangiopathy (15/788, 1.90%) and other congenital heart abnormalities (21/972, 2.16%) than in the atrial septal defect (10/1 015, 0.99%) and patent ductus arteriosus (6/565, 1.06%) groups (P < 0.05). There were no statistically significant differences in the type of hypospadias among different heart disease groups (P > 0.05).

CONCLUSIONHypospadias is a common concurrent condition in male children with congenital heart disease. The incidence rate of hypospadias is related with the type of congenital heart disease, and the two conditions may have some common pathogenic or susceptive factors.

BACKGROUNDMetabolic syndrome (MetS) and atrial fibrillation (AF) are causally related. This study aimed to determine the prevalence of MetS in patients with AF in the absence of structural heart disease from a tertiary hospital in China.

METHODSIn a single center, 741 inpatients with AF in the absence of structural heart disease prior to catheter ablation were retrospectively reviewed. Among them, 588 (79.4%) patients had paroxysmal AF. Subgroup analyses were performed in paroxysmal AF and persistent/permanent AF.

RESULTSMetS was found in 343 (46.3%) patients (200 males, 143 females); 0, 1, 2, 3, 4, 5 components of the MetS were found in 59 (8.0%), 140 (18.9%), 199 (26.9%), 203 (27.4%), 103 (13.9%) and 37 (5.0%) patients, respectively. The prevalences of overweight/obesity, high blood pressure, high glucose level, high triglyceride level and low high density lipoproteins cholesterol level were 53.8%, 47.6%, 23.2%, 40.6% and 72.1%, respectively. The prevalence of MetS was not significantly different between the paroxysmal AF group and the persistent/permanent AF group (44.6% vs 52.9%, P = 0.064). The five components of MetS except overweight/obesity (69.3% vs 49.8%, P < 0.001) were not significantly different between the aforementioned two groups. The left atrium diameter increased with the sum of the MetS components. The left atrium diameter in the MetS group was significantly higher than that in the non-MetS group both in patients with paroxysmal AF and in patients with persistent/permanent AF.

CONCLUSIONSThe prevalence of MetS in patients with AF prior to catheter ablation is high. Further study and prevention are needed.

BACKGROUND: In the general population, the incidence of bundle branch block (BBB) is relatively low, and its effects on long-term prognosis have not been established. Previous studies on the incidence and correlation of BBB to clinical factors have produced conflicting results. However, the incidence of BBB was strongly related to age. This study aimed to describe the incidence of and risk factors for BBB in Korea. METHODS: In this study, 14, 540 adults (male 6, 573/female 7, 967) > or=40 years old received screening tests for general health between April and December 2000. Participants answered questionnaires and underwent examinations, which included blood pressure, electrocardiogram (ECG), total cholesterol and fasting glucose. The data analysis was performed using SPSS 10.0 for windows. RESULTS: The incidences of complete right bundle branch block (CRBBB) were 1.5 and 2.9% in people older than 40 and 65 years, respectively. Approximately 38.0% of individuals with CRBBB were older than 65 years. The incidence of CRBBB was higher in men than women at all age groups was highest in those aged 75-79 years. Males, advancing age (> or=65 years), hypertension and diabetes mellitus (DM) were associated with an increased risk of CRBBB. The incidences of complete left bundle branch block (LBBB) and bifascicular bundle branch block (BBBB) were 0.1 and 0.08% and 0.3 and 0.2% in those older than 40 and 65 years, respectively. Approximately 71.4 and 58.3% of individuals with LBBB and BBBB, respectively, were older than 65 years. Advancing age and cardiac disease were associated with an increased risk of LBBB. Advancing age was associated with an increased risk of BBBB. The most potent risk factor for BBB in this study was advancing age. CONCLUSION: The incidences of BBB were 1.7 and 3.4% in those older than 40 and 65 years respectively. Bundle branch block correlates strongly with age, and is common in the older ages groups. These findings support the theory that bundle branch block is a marker of slowly progressing degenerative diseases.

PURPOSE: This study was done to compare demographic characteristics, comorbidity, and health habits of elders with mild cognitive impairment (MCI) and elders with cognitively normal function (CNF). METHODS: Secondary data analysis was conducted using data from the Database of the Seoul Dementia Management Project for 5,773 adults age 60 and above. RESULTS: The MCI group showed an older age distribution, but there was no significant education difference between the two groups. Elders with MCI had more diabetes and stroke than elders with CNF. In subgroups, the same findings were observed in women, but not in men. While more men with MCI had hypertension compared to men with CNF, there was no significant difference in hypertension between the two groups for women. Elders with MCI, men in particular, had a lower prevalence of obesity than men with CNF. MCI individuals did less exercise compared to individuals with CNF. While there were no significant differences in alcohol consumption and smoking between MCI and CNF groups, the over 80's subgroup with MCI reported more alcohol consumption. CONCLUSION: Findings from this study could be helpful in designing community-based dementia prevention programs and health policies to reduce the prevalence of dementia or related cognitive impairments.

PURPOSE: Although cardiac involvement is an infrequently recognized manifestation of venomous snakebites, little is known of the adverse cardiovascular events (ACVEs) arising as a result of snakebite in Korea. Accordingly, we studied the prevalence of ACVEs associated with venomous snakebites in Korea and compared the clinical features of patients with and without ACVEs. MATERIALS AND METHODS: A retrospective review was conducted on 65 consecutive venomous snakebite cases diagnosed and treated at the emergency department of Wonju Severance Christian Hospital between May 2011 and October 2014. ACVEs were defined as the occurrence of at least one of the following: 1) myocardial injury, 2) shock, 3) ventricular dysrhythmia, or 4) cardiac arrest. RESULTS: Nine (13.8%) of the 65 patients had ACVEs; myocardial injury (9 patients, 13.8%) included high sensitivity troponin I (hs-TnI) elevation (7 patients, 10.8%) or electrocardiogram (ECG) determined ischemic change (2 patients, 3.1%), and shock (2 patient, 3.1%). Neither ventricular dysrhythmia nor cardiac arrest was observed. The median of elevated hs-TnI levels observed in the present study were 0.063 ng/mL (maximum: 3.000 ng/mL) and there was no mortality in the ACVEs group. Underlying cardiac diseases were more common in the ACVEs group than in the non-ACVEs group (p=0.017). Regarding complications during hospitalization, 3 patients (5.4%) in the non-ACVEs group and 3 patients (33.3%) in the ACVEs group developed bleeding (p=0.031). CONCLUSION: Significant proportion of the patients with venomous snakebite is associated with occurrence of ACVEs. Patients with ACVEs had more underlying cardiac disease and bleeding complication.

OBJECTIVETo study whether hypoalbuminemia after pediatric cardiopulmonary bypass (CPB) for cardiac surgery is a risk factor for postoperative acute kidney injury (AKI).

METHODSA retrospective analysis was performed on the clinical data of 1 110 children who underwent CPB surgery between 2012 and 2016. According to the minimum serum albumin within 48 hours postoperatively, these patients were divided into hypoalbuminemia group (≤35 g/L) and normal albumin group (>35 g/L). The two groups were compared in terms of perioperative data and the incidence of AKI. Furthermore, the incidence of AKI was compared again after propensity score matching for the unbalanced factors during the perioperative period. The perioperative risk factors for postoperative AKI were analyzed by logistic regression.

RESULTSThe overall incidence rate of postoperative AKI was 13.78% (153/1 110), and the mortality rate was 2.52% (28/1 110). The mortality rate of children with AKI was 13.1% (20/153). The patients with hypoalbuminemia after surgery (≤35 g/L) accounted for 44.50% (494/1 110). Before and after propensity score matching, the hypoalbuminemia group had a significantly higher incidence of AKI than the normal albumin group (P<0.05). The children with AKI had a significantly lower serum albumin level after surgery than those without AKI (P<0.05). The multivariate logistic regression analysis showed albumin ≤35 g/L was one of the independent risk factors for postoperative AKI.

CONCLUSIONSAlbumin ≤35 g/L within 48 hours postoperatively is an independent risk factor for postoperative AKI in children after CPB surgery.

OBJECTIVETo explore the clinical characteristics and risk factors of peripheral arterial thromboembolism (PAT) in patients with non valvular atrial fibrillation (NVAF).

METHODSA total of 18 456 patients admitted in our hospital and diagnosed with NVAF were included in this study. The study population was divided into three groups [PAT group, cerebral thromboembolism (CT) group and no thromboembolism group]. Risk factors of PAT were assessed by multivariate logistic regression.

RESULTSThe incidence of PAT and CT was 1.1% (204 cases) and 27.8% (5 132 cases), respectively. The in-hospital mortality of PAT group was 11.8% (24/204), in which the in-hospital mortality due to mesenteric arterial thromboembolism (37.5%, 6/16) was the highest. Multivariate logistic regression indicated that vascular disease (OR = 3.9, 95% CI 2.13-7.08, P < 0.01), age ≥ 65 years (OR = 2.7, 95% CI 1.66-4.27, P < 0.01), hypertension (OR = 2.1, 95% CI 1.36-3.34, P < 0.01), history of stroke/TIA/arterial thromboembolism (OR = 2.0, 95% CI 1.26-3.17, P < 0.01) and congestive heart failure (OR = 1.9, 95% CI 1.22-2.86, P < 0.01) were independent risk factors of PAT. Prevalence of vascular disease and histories of PAT was higher in PAT group than in CT group (P < 0.01), while CHADS2 and CHA2DS2VASc scores were similar between the PAT and CT groups.

CONCLUSIONPAT is not uncommon in NVAF patients, risk factors for PAT in NVAF patients are vascular disease, advanced age, hypertension, history of stroke/TIA/arterial thromboembolism and congestive heart failure.

OBJECTIVEThe aim of the study was to review the cases of Kawasaki Disease (KD) and analyze the clinical features especially their cardiac complications.

METHODSTotally 283 patients with KD were hospitalized from 1992 to 2002. Their clinical features and factors associated with increased risk of coronary artery aneurysms were reviewed.

RESULTS(1) Among the 283 KD patients, 186 were male and 97 were female. The male-female ratio was 1.9:1. Most of them (71%) were younger than 3 years old. Seasonal peak was in spring and summer (from May to Aug). Depending on the criteria of KD, 228 (81%) were diagnosed as typical KD and 55 (19.4%) were atypical KD. All patients had fever, lasting for 6.1 days. The most common clinical features were oral mucosal changes (97.5%) and cervical lymphadenopathy (95.4%), conjunctivitis (91.2%). And changes in the extremities (89.8%) and rash (81.5%) were also noted. (2) Before the treatment, coronary artery abnormalities were seen in 103/279 (36.9%), which occurred within 4 - 30 days of fever onset. Two weeks after intravenous gamma globulin (IVIG) treatment, the new cases of coronary artery abnormalities were 28/211 (13.3%). The prevalence of coronary artery aneurysms (CAA) with KD was 4.7%. The risk factors of CAA were male cases (P < 0.05) and fever lasting longer than 9 days (P < 0.05). Other cardiac abnormalities in acute phase included left atrial and ventricular enlargement (40/279, 14.3%) and changes in ECG (57/274, 20.8%). The pericardial effusions were found in 11 cases (3.9%).

CONCLUSIONSCardiac complications of KD occurred in the early period of KD. The new cases of coronary artery abnormalities were 13.3% after IVIG treatment. The risk factors of CAA included male cases and fever lasting for longer time.

Triple valve surgery is usually complex and carries a reported operative mortality of 13% and 10-yr survival of 61%. We examined surgical results based on our hospital's experience. A total of 160 consecutive patients underwent triple valve surgery from 1990 to 2006. The most common aortic and mitral valve disease was rheumatic disease (82%). The most common tricuspid valve disease was functional regurgitation (80%). Seventy-four percent of the patients were in New York Heart Association (NYHA) class III and IV. Univariate and multivariable analyses were performed to identify predictors of early and late survival. Operative mortality was 6.9% (n=11). Univariate factors associated with mortality included old age, preoperative renal failure, postoperative renal failure, pulmonary complications, and stroke. Of them, postoperative renal failure and stroke were associated with mortality on multivariable analysis. Otherwise, neither tricuspid valve replacement nor reoperation were statistically associated with late mortality. Survival at 5 and 10 yr was 87% and 84%, respectively. Ninety-two percent of the patients were in NYHA class I and II at their most recent follow-up. Ten-year freedom from prosthetic valve endocarditis was 97%; from anticoagulation-related hemorrhage, 82%; from thromboembolism, 89%; and from reoperation, 84%. Postoperative renal failure and stroke were significantly related with operative mortality. Triple valve surgery, regardless of reoperation and tricuspid valve replacement, results in acceptable long-term survival.

OBJECTIVES: The goal of this study was to identify association between the continuity of ambulatory care of diabetes patients in South Korea (hereafter Korea) and the incidence of macrovascular complications of diabetes, using claims data compiled by the National Health Insurance Services of Korea. METHODS: This study was conducted retrospectively. The subjects of the study were 43 002 patients diagnosed with diabetes in 2007, who were over 30 years of age, and had insurance claim data from 2008. The macrovascular complications of diabetes mellitus were limited to ischemic heart disease and ischemic stroke. We compared the characteristics of the patients in whom macrovascular complications occurred from 2009 to 2012 to the characteristics of the patients who had no such complications. Multiple logistic regression was used to assess the effects of continuity of ambulatory care on diabetic macrovascular complications. The continuity of ambulatory diabetes care was estimated by metrics such as the medication possession ratio, the quarterly continuity of care and the number of clinics that were visited. RESULTS: Patients with macrovascular complications showed statistically significant differences regarding sex, age, comorbidities, hypertension, dyslipidemia and continuity of ambulatory diabetes care. Visiting a lower number of clinics reduced the odds ratio for macrovascular complications of diabetes. A medication possession ratio below 80% was associated with an increased odds ratio for macrovascular complications, but this result was of borderline statistical significance. CONCLUSIONS: Diabetes care by regular health care providers was found to be associated with a lower occurrence of diabetic macrovascular complications. This result has policy implications for the Korean health care system, in which the delivery system does not work properly.
