Dysregulation of autonomic nervous system dynamics is important in the pathophysiology of cardiovascular risk in obstructive sleep apnea (OSA). Heart rate variability (HRV) and impedance cardiography measures can estimate autonomic…
Caregivers might represent an opportunity to improve cardiovascular disease outcomes, but prospective data are limited. We studied 3,188 consecutive patients (41% minority, 39% women) admitted to a university hospital medical…
High-sensitivity C-reactive protein (hs-CRP) is a marker for the risk of cardiovascular and overall mortality. However, information about the association between hs-CRP and mortality in patients with atrial fibrillation is…
The effects of medications on the outcome of aortic dissection remain poorly understood. We sought to address this by analyzing the International Registry of Acute Aortic Dissection (IRAD) global registry…
The tricuspid annular peak systolic velocity (TAPSV) is an echocardiographic measurement assessing right ventricular systolic function in children and adults. We determined the growth-related changes of the TAPSV to establish…
Cardiology professional societies have recommended that patients with cardiovascular implantable electronic devices complete advance directives (ADs). However, physicians rarely discuss end of life handling of implantable cardioverter defibrillators (ICDs), and…
Analogous to rapid ventricular pacing, frequent ventricular premature complexes (VPCs) can predispose over time to cardiomyopathy and subsequent heart failure (HF). We examined the association of frequent VPCs with HF…
Repeated sauna treatment, known as Waon therapy, has been shown to improve cardiac function as well as exercise tolerance in patients with chronic heart failure. However, the underlying mechanisms of…
Fragmented QRS (fQRS) on 12-lead electrocardiography reflects conduction delay caused by myocardial fibrosis and dysfunction. Ventricular fibrosis detected by late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) is reportedly correlated…
Diabetes mellitus and obesity are increasing in prevalence and are associated with an elevated risk of atrial fibrillation (AF). Given the aging of the United States population, AF is projected…
