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...
Heterotopic ossification (HO) is an unclear etiological trigger that results in diverse extra-skeletal bone formation muscles and soft tissues. This often morbidity reduced quality of life with pain, contractures, mobility impairment. We present two patients HO a history severe COVID-19 infection requiring 1-month-long mechanical ventilation. The first patient was found to have progressive stiffening the right knee left elbow, clear demonstration radiographic findings active dystrophic...
Objectives: We compare the prevalence and health behavior indicators of hypertension, diabetes, metabolic syndrome, dyslipidemia, other behaviors between Gangwondo national average in South Korea using data National Health Nutrition Examination Survey (KNHANES) from 2013 to 2021.Methods: KNHANES was analyzed for adults aged 19 older, with a focus on those 30+ diabetes-related analyses. Age-standardized rates were used, weighted integration by survey cycle ensure reliability smaller sample...
Adoptive immunotherapy with interleukin-2 (IL-2) and lymphokine-activated killer (LAK) cells has been effective in treating some advanced malignancies animals humans. One complication of this treatment is a reversible, oliguric, acute renal failure, which ascribed to hypoperfusion resultant prerenal azotemia. We serially studied function 10 patients receiving high-dose regimens recombinant (rIL-2) attempt delineate further the nature dysfunction caused by IL-2 treatment. Renal plasma flow...
Abstract Background and objectives This study aimed to analyze present updated trends in atrial fibrillation (AF) epidemiology within the Korean population, providing a foundation for planning implementing appropriate management treatment strategies patients with AF. Patients methods We used National Health Insurance Service database evaluate prevalence, incidence, comorbidities, clinical adverse outcomes of AF Korea between 2013 2022. Results prevalence adults aged ≥ 20 years doubled (1.1...
Objective: To evaluate predictors and long-term prognosis of atrial fibrillation (AF) following cardiac implantable electronic device (CIED) implantation in patients without history AF. Methods: From May 1994 to April 2014, 1825 with CIED were enrolled a retrospective, single-center registry. A total 880 from the registry prior documented AF included final analysis placed into either non-detected (NDAF) group or CIED-detected according development over follow-up period 7 years. was defined...
Most patients with idiopathic ventricular premature depolarizations (VPDs) complain of symptoms related to this arrhythmia, but some are asymptomatic even a high VPD burden. Our understanding the relationship between and cardiomyopathy arrhythmia remains limited. We evaluated 801 subjects (381 men; mean age, 55 ± 17 years) who visited our outpatient clinic. All were diagnosed frequent VPDs (1% or >1000 beats/day). The divided into two groups according presence absence typical (palpitations...
There are few data on the absolute effects of sodium/glucose cotransporter 2 (SGLT2) inhibitors, despite their importance in treatment decision making. We investigated according to baseline kidney disease status.Meta-analysis.Adults with type diabetes, chronic disease, or heart failure.Randomized controlled trials SGLT2 inhibitors (10 November 20, 2020) for clinical outcomes progression, failure events, and major cardiovascular events.Publications 10 2020.The incidence rate difference (IRD)...
Little is known about the long-term prognosis of or predictors for different clinical types atrial fibrillation (AF) in Korean populations. The aim this study was to validate a risk stratification assess probability AF progression from paroxysmal (PAF) persistent (PeAF) permanent AF. A total 434 patients with PAF were consecutively enrolled (mean age; 71.7 ± 10.7 yr, 60.6% male). PeAF defined as episodes that are sustained > 7 days and not self-terminating, while an ongoing episode. Atrial...
The association between daytime/nighttime heart rate variability (HRV) and the apnea-hypopnea index (AHI) remains unclear. We sought a relationship AHI daytime-to-nighttime HRV ratio as measured by 24-hour Holter monitoring in patients with obstructive sleep apnea.We prospectively enrolled 66 who visited our clinic complaining of habitual snoring or apnea. All underwent (to measure HRV) combined full-night polysomnography. Sixty-two met enrollment criteria. evaluated associations frequency...
Purpose: This study aimed to determine whether upgrade cardiac resynchronization therapy (CRT) shows better outcomes than de novo CRT.To do so, we compared the efficacy of CRT between and groups, focusing particularly on effect patients with pacing-induced cardiomyopathy (PiCM).Materials Methods: PiCM was defined as new-onset dilated following pacemaker implantation in baseline normal ejection fraction ≥50%.Electro-mechanical reverse remodeling clinical were among (n=62), (n=7), non-PiCM...
The relative efficacy of antiarrhythmic drugs (AADs) after electrical cardioversion are not well established. This study aimed to investigate the efficacies different AADs for maintaining sinus rhythm (SR) atrial fibrillation (AF). We selected patients from a retrospective registry including admitted between January 2012 and June 2016. primary outcome was time AF recurrence during first year cardioversion. secondary outcomes included within 1 month, readmission due heart failure, stroke, or...
There is no clinical evidence about the effect of sodium-glucose cotransporter-2 (SGLT2) inhibitors on diabetic patients who have been diagnosed with coronavirus disease 19 (COVID-19).
Frequent ventricular premature complex (VPC) is one of the most common arrhythmia syndromes. Symptoms observed frequently with this syndrome remain limited. We sought to identify predictors VPC-related symptoms by analyzing demographic information, VPC burden, and surface electrocardiogram characteristics.We prospectively enrolled 109 patients idiopathic outflow tract VPCs (63 males, 49±16 years old). They were divided into Group A (n=30, without palpitations or "dropped beats") B (n=79,...
