OBJECTIVE The objective was to determine the effect of radiofrequency catheter ablation (RFA) on progression of paroxysmal atrial fibrillation (AF). BACKGROUND Progression to persistent AF may occur in up to 50% of patients with paroxysmal AF receiving pharmacological therapy. Hypertension, age, prior transient ischemic event, chronic obstructive pulmonary disease, and heart failure (HATCH sc...
BACKGROUND/AIMS There are no data concerning renal function in population with valvular and non-valvular atrial fibrillation (AF). To assess renal function in patients with AF, the association between eGFR and AF perpetuation, in-hospital mortality. METHODS We studied 1523 patients with AF. Patients with chronic kidney disease (CKD) were compared to population with preserved renal function. ...
OBJECTIVE Atrial fibrillation (AF) is frequently detected after ischemic stroke for the first time, and brain regions involved in autonomic control have been suspected to trigger AF. We examined whether specific brain regions are associated with newly detected AF after ischemic stroke. METHODS Patients with acute cerebral infarctions on diffusion-weighted magnetic resonance imaging were inclu...
BACKGROUND Atrial fibrillation (AF) patterns and their relations with long-term prognosis are uncertain, partly because pattern definitions are challenging to implement in longitudinal data sets. We developed a novel AF classification algorithm and examined AF patterns and outcomes in the community. METHODS AND RESULTS We characterized AF patterns between 1980 and 2005 among Framingham Heart ...
BACKGROUND AND PURPOSE Atrial fibrillation (AF) is a risk factor for stroke, although it may not always be directly responsible for the stroke. On the other hand, cardiac arrhythmias and electrocardiographic changes have been reported after ischemic stroke and numerous other intracranial pathologies. We tested the hypothesis that some patients with acute stroke may develop transient AF as a con...
AIMS To characterize the relationship between known and newly diagnosed atrial fibrillation (AF) and the risk of death and major cardiovascular (CV) events in patients with acute myocardial infarction (MI) complicated by heart failure (HF) and/or left ventricular systolic dysfunction (LVSD). METHODS The VALIANT trial enrolled 14,703 individuals with acute MI complicated by HF and/or LVSD. AF ...
