Brain natriuretic peptide (BNP) is a marker of systolic and diastolic dysfunction and a strong predictor of mortality in heart failure patients. The present study aimed to assess the relationship…
We sought to determine whether preoperative baseline echocardiographic analysis and the type of surgical procedure are predictive of the magnitude and timing of postoperative left ventricular (LV) remodeling in patients…
Quantitative assessment of aortic regurgitation (AR) remains challenging. The present study evaluated the accuracy of 2-dimensional (2D) and 3-dimensional (3D) transthoracic echocardiography (TTE) for AR quantification, using 3D 3-directional velocity-encoded…
Although a number of publications have described the natural history of patients with aortic stenosis (AS), the definition of “natural history” varies widely. Those describing a large number of patients…
Conduction disorders and permanent pacemaker implantation are common complications in patients who undergo transcatheter aortic valve implantation (TAVI). The aim of this study was to assess the incidence and clinical…
Whether autonomic dysfunction predates the development of symptomatic heart failure (HF) or is simply a consequence of severe HF is unknown. We hypothesized that reduced heart rate variability (a marker…
Although extending the duration of ambulatory electrocardiographic monitoring beyond 24 to 48 hours can improve the detection of arrhythmias, lead-based (Holter) monitors might be limited by patient compliance and other…
A post hoc analysis of the Multicenter Automatic Defibrillator Implantation Trial (MADIT) II showed that patients with high mortality risk score did not benefit from implantable cardioverter-defibrillator (ICD) therapy. We…
The association between serum uric acid (SUA) levels and atrial fibrillation (AF) is currently poorly known. We examined the association between SUA levels and risk of incident AF in patients…
Dofetilide is a class III antiarrhythmic agent approved for the maintenance of sinus rhythm in patients with persistent atrial fibrillation (AF). The goal of this study was to determine if…
