Vascular endothelium has important regulatory functions in the cardiovascular system and a pivotal role in the maintenance of vascular health and metabolic homeostasis. It has long been recognized that endothelial dysfunction participates in the pathogenesis of atherosclerosis from early, preclinical lesions to advanced, thrombotic complications. In(More)
Stroke prevention in atrial fibrillation (AF) has been challenging over decades, mostly due to a number of difficulties associated with oral vitamin K antagonists (VKAs), which have been the most effective stroke prevention treatment for a long time. The oral direct thrombin inhibitors (e.g., dabigatran) and oral direct inhibitors of factor Xa (e.g.,(More)
Previously, endocarditis caused by Pseudomonas aeruginosa mostly involved right-sided valvular infection and generally carried a good prognosis. Recently, changes have been observed in the occurrence and clinical presentation of pseudomonal endocarditis, with increasing incidence of nosocomial infections and involvement of the aortic and mitral valves.(More)
BACKGROUND The CHA(2)DS(2)-VASc (Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, previous Stroke/transient ischemic attack [TIA], Vascular disease, Age 65-74 years, and Sex category [female gender]) schema recently has been introduced to complement the CHADS(2) (Congestive heart failure, Hypertension, Age >75 years, Diabetes(More)
BACKGROUND Lone atrial fibrillation (AF) has been suggested to have a favorable long-term prognosis. Significant interest has been directed at factors predicting arrhythmia progression, and the HATCH score (hypertension, age ≥ 75 years, transient ischemic attack or stroke [2 points], COPD, and heart failure [2 points]) recently has been proposed as a(More)
BACKGROUND To investigate baseline characteristics and long-term prognosis of carefully characterized asymptomatic and symptomatic patients with atrial fibrillation (AF) in a 'real-world' cohort of first-diagnosed non-valvular AF over a 10-year follow-up period. METHODS AND RESULTS We conducted an observational, non-interventional, and single-centre(More)
BACKGROUND Many blood biomarkers have a positive association with stroke outcome, but adding blood biomarkers to the National Institutes of Health Stroke Scale (NIHSS) did not significantly improve its discriminatory ability. We investigated the association of the CHA2DS2-VASc score with unfavourable functional outcome (defined as a 30-day modified Rankin(More)
BACKGROUND Many atrial fibrillation (AF) patients have a poor understanding of the management of this condition. We investigated patient attitudes towards AF and a potential invasive treatment following an average 10-year period of prospective rhythm control in a cohort of newly diagnosed AF patients. METHODS This was a prospective registry-based study.(More)
BACKGROUND Several studies have investigated gender-related differences in atrial fibrillation (AF), but limited data are available in relation to gender-related differences in presentation, treatment and long-term outcomes of patients with first-diagnosed AF and structurally normal heart. OBJECTIVE To compare gender-related clinical characteristics,(More)
Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia in adult population and confers significant thromboembolic risk. Endothelial dysfunction has been recognized as a possible contributor to thrombogenesis in AF. The arrhythmia has been associated with thrombogenic atrial endocardial lesions and evidence of increased circulating(More)
