Cryoballoon ablation (CBA) is considered an effective rhythm control treatment for atrial fibrillation (AF) and increasing exponentially. However, data regarding the efficacy safety of CBA in elderly patients are limited. A total 2,652 (55.2% with non-paroxysmal AF) from Korean registry database follow-up ≥12-months after de novo were divided into 2 groups based on age (<75 ≥75 years old). Procedure related complications clinical outcomes compared. Compared to group (n=2,403), (n=249) had...
Background The ECG is a simple, noninvasive screening method for cardiovascular disease and arrhythmia. impact of abnormality on mortality not certain in low‐risk populations. To address this, we evaluated the association between mortality. Methods Results We retrospectively assessed baseline all‐cause 660 383 patients presenting medical check‐ups. Baseline abnormalities were classified according to Minnesota Code. Among total participants, 23 609 (3.6%) had major 110 038 (16.7%) minor...
Background: Strict blood pressure control can be used to prevent or treat cerebral hyperperfusion syndrome. This study investigated whether scalp nerve block (SNB) is associated with a reduced risk of postoperative symptomatic syndrome (SCHS) by reducing in adult patients who underwent combined revascularization surgery for moyamoya disease. Methods: Patients were retrospectively divided into the SNB (n=167) and (n=221) groups depending on was performed immediately before placement wound...
Few studies have investigated the association between coronary artery calcium (CAC) progression and arterial stiffness measured by brachial-ankle pulse wave velocity (baPWV). We examined influence of severity baseline baPWV on CAC in a large prospective cohort.A total 1600 subjects who voluntarily participated comprehensive health-screening program March 2010 December 2013 had as well serial follow-up computed tomography performed approximately 2.7 ± 0.5 years apart were enrolled study.A...
Objective: Previous studies have reported the association among serum uric acid (SUA) levels and cardiovascular all-cause mortality; however, results been inconsistent. The aim of this study was to investigate whether SUA is independently associated with mortality in relatively healthy Korean adults. Methods: A total 396 951 individuals were enrolled for between 2002 2012. About 39 991 participants excluded various reasons. All-cause data collected. Cox proportional hazards models used...
BACKGROUND: Despite improvements in medical technology, lung cancer metastasis remains a global health problem. The effects of microgravity on cell morphology, structure, functions, and their mechanisms have been widely studied; however, the biological simulated interaction between cells its eventual influence characteristics are yet to be discovered. We examined metastatic ability different using random positioning machine. METHODS: Human lines adenocarcinoma (A549) squamous carcinoma...
Abstract BACKGROUND It is uncertain whether high-baseline uric acid (UA) or change in UA concentration over time related to development of incident hypertension. To investigate relationships between: (i) baseline serum and (ii) METHODS About 96,606 Korean individuals (with follow-up data available for 56,085 people) participating a health check program was undertaken. Cox regression models were used estimate adjusted hazard ratios (aHRs) 95% confidence intervals (CIs) hypertension according...
