The autonomic nervous system (ANS) plays an important role in the initiation and maintenance of atrial fibrillation (AF). However, meaning higher heart rate variability (HRV) predicting AF remains unclear. Among 2100 patients Holter registry, a total 782 hypertensive were included this study. Baseline HRV was measured by time domain frequency methods using 24-h monitoring. primary outcome development AF. During average follow-up 1.1 years, 44 developed Higher parameters including...
Despite the high burden and frequency of urticaria, its epidemiology is not well known. We investigated various type urticaria in Korea changes annual prevalence over 5 years.We used data from 2010 to 2014 Health Insurance Review Assessment database, which covers claims 97.0% South Korean population. Patients aged > 10 years old were included this study. The presence was identified on physician-certified diagnoses using International Classification Diseases 10th Revision (ICD-10) codes that...
Background Recently, diastolic stress testing and invasive hemodynamic measurements have been emphasized for diagnosis of heart failure with preserved ejection fraction (HFpEF) because when determined using noninvasive parameters it can fall into a nondiagnostic intermediate range. The current study evaluated the discriminative prognostic roles measured left ventricular end‐diastolic pressure in population suspected HFpEF, particularly patients Heart Failure Association Pre‐test Assessment,...
Although some peripartum-associated cardiomyopathy patients present with features that are clinically and echocardiographically similar to those of takotsubo (TCM), little is known about the diagnosis clinical course peripartum TCM.In a tertiary hospital in Seoul, Korea, we searched database find cases were associated pregnancy from January 1995 May 2019. Applying published diagnostic criteria, sought (PPCM) TCM for comparison. Of 31 pregnancy-associated patients, 10 21 PPCM found. Maternal...
Recently, clinical research has suggested that red ginseng components play a role in liver protection and combating fatigue. However, fermented not been analyzed for liver-protective or anti-fatigue effects.This study evaluates the positive effects of powder (GBCK25) on function.Ninety participants with elevated alanine aminotransferase levels (35 ≤ ALT ≤1 05 IU/L) were randomized to one three groups. The treated GBCK25 tablets at dose 500 mg/day (high dose), 125 (low placebo group daily 12...
The pressure increase per time unit (dP/dt) in aortic stenosis (AS) jet velocity is assumed to have inter-individual variability the progressive AS stage. We sought examine association of valve (AoV) Doppler-derived dP/dt patients with mild moderate risk progression severe disease.A total 481 diagnosed or [peak (Vmax) between 2 and 4 m/s] according echocardiographic criteria were included. AoV was determined by measuring needed for at a from 1 m/s m/s. During median follow-up period 2.7...
A bstract : The signaling pathways mediating cytokine production and apoptosis in pancreatic acinar cells have not been fully understood. We investigated the signal transduction of cerulein‐induced IL‐6 expression AR42J cells. wild‐type transfected with mutant genes for molecules (such as transcription factor NF‐κB AP‐1) ras, upstream mitogen‐activated protein kinase (MAPK), were used. level was determined medium by enzyme‐linked immunosorbent assay (ELISA). Apoptosis viable cell counts DNA...
Abstract Aims Tricuspid valve (TV) surgery for functional tricuspid regurgitation (TR) is becoming more common, but the associated mortality remains high. Therefore, we evaluated clinical and echocardiographic parameters with all‐cause in patients severe TR who underwent TV surgery. Methods results A total of 286 replacement or repair was analysed between January 2006 December 2017. We assessed changes conventional strain, such as peak atrial longitudinal strain (PALS). During a median...
Cardiac angiography to visualize the cardiac coronary artery for lesions causes a lot of radiation exposure dose interventional cardiologist. We evaluated occupational cardiologist based on changes angle X-ray tube used in and calculated conversion factor effective this study. To evaluate resulting from scattered cardiologists, organ doses eyeball, thyroid, heart were using Monte Carlo simulation with korean typical man(KTMAN) phantom at left anterior oblique (LAO)30/cranial (CRAN)30,...
Background and Aims . Endoscopic submucosal dissection (ESD) is routinely performed in treating gastric neoplasia requires long-term higher levels of sedation. Endoscopist-directed nurse-administered sedation (EDNAS) has not been well studied ESD. This study aimed to evaluate the safety effectiveness EDNAS for Methods Patients treated with ESD tumors between 2013 2015 were retrospectively collected. divided into a midazolam-treated group (M group) midazolam plus propofol-treated (MP group)....
Pulmonary extraintestinal manifestation is rare in Crohn's disease and has been reported only a few cases. Despite the presence of pulmonary abnormalities significant proportion patients with inflammatory bowel disease, there are case reports, due to complicated diagnosis low recognition by clinicians. Currently, treatment guidelines for have not established. There some reports that achieved remission after infliximab treatment. Clinical radiological involvement adalimumab therapy yet. Here,...
Total ischemic time (TIT) is an important factor for predicting mortality among patients with ST-segment elevation myocardial infarction (STEMI). However, the correlation between TIT and extent of wall motion abnormality has not been well studied. Therefore, we investigated changes in score index (WMSI) value based on STEMI who underwent primary percutaneous coronary intervention (PCI) subsequent transthoracic echocardiography.STEMI PCI follow-up angiography were analyzed after exclusion...
Background Little research has been assessed atherosclerotic risk factors at various stages of calcific aortic valve disease. This study sought to determine patients with sclerosis (AVS) and mild moderate stenosis (AS). Methods The included 1,007 diagnosed AVS or AS according echocardiographic criteria. Patients were identified as a rapid progression group if the annualized difference in peak jet velocity (Vmax) between two examinations was >0.08 m/s/yr >0.3 AS, respectively....
Recurrence of any atrial arrhythmia after surgical ablation is known as a negative predictor cardiovascular events and total mortality. However, there have been no focused studies for fibrillation (AF) recurrence prediction in patients with significant tricuspid regurgitation (TR), the risk-benefit estimation valve (TV) surgery not fully established.We screened 385 who underwent TV operation between 2001 2017. After excluding did undergo maze operation, 158 were enrolled. Enrolled divided by...
The purpose of this study was to analyze the effects health class activities for elementary students on body composition and physical fitness provide fundamental data essential devising suitable exercise programs them. A total 18 participants with mass index 20% or more(mild obesity) from J Elementary School in G Metropolitan City were selected study. over a 12-week period analyzed. Data analysis performed using IBM SPSS Statistics 23.0. Descriptive statistics employed calculate mean...
In the medical domain, computer systems in digital healthcare have increased connectivity continuously and DICOM Message Service Element (DIMSE) protocol has a critical role exchanging biomedical imaging data among different systems. As communication technology is used to handle sensitive information such as patient (e.g., patient’s name, date of birth, address) images ultrasound, X-ray, MRI), it emerged major target for security attacks. this work, we study concerns on message exchange...
Statins are thought to have little effect on the progression of aortic stenosis, but data their role in patients with valve sclerosis (AVS) limited and inconsistent.We retrospectively analyzed 541 consecutive (214 men, age: 70 ± 11 years) AVS. Each patient underwent two or more electrocardiography examinations at least 6 months apart Kangwon National University Hospital from August 2010 2015. AVS is defined as irregular thickening leaflets, focal increases echogenicity minimal elevation peak...
Background The prognostic role of myocardial ischemia in patients with heart failure preserved ejection fraction (HFpEF) has not been fully elucidated. Therefore, we investigated the change echocardiographic parameters and clinical outcomes based on presence epicardial coronary artery disease (CAD) positive stress tests HFpEF patients. Methods Symptomatic left ventricular end diastolic pressure ≥15 mmHg who underwent angiography were analyzed between January 2000 August 2019 after exclusion...
