BACKGROUND Pulmonary embolism (PE) may trigger atrial fibrillation through increased right atrial pressure and subsequent atrial strain, but the degree of evidence is low. In this study, we wanted to investigate the impact of incident venous thromboembolism (VTE) on future risk of atrial fibrillation in a prospective population-based study. METHODS AND RESULTS The study included 29 974 subjec...

Atrial fibrillation (AF) may appear during the natural clinical course of hypertrophic cardiomyopathy (HCM). It is regarded as a complication of HCM and is a marker of advanced disease. AF is more likely to occur in untreated, obstructive HCM. Unfortunately, this represents a turning point that puts patients at increased risk of further disability, stroke and death. The presence of obstruction ...

The effect of surgical ablation of atrioventricular accessory pathways on the incidence of atrial fibrillation in patients with Wolff-Parkinson-White syndrome was examined and the results of preoperative electrophysiologic testing were studied to determine factors predictive of outcome. Among 50 consecutive surgical cases, 19 patients were identified with a past history of at least one episode ...

2. Atrial Fibrillation/Flutter: Most common use of Holter in this setting is to diagnose transient atrial fibrillation. There is a unique application of Holter ECG in atrial fibrillation, that is particularly in understanding the relationship to autonomically mediated atrial fibrillation. After the diagnosis has been made Holter is used to assist the efficacy of anti-arrhythmic drugs in suppres...

BACKGROUND The occurrence of atrial fibrillation after ablation of type I atrial flutter remains an important clinical problem. To gain further insight into the pathogenesis and significance of postablation atrial fibrillation, we examined the time to onset, determinants, and clinical course of atrial fibrillation after ablation of type I flutter in a large patient cohort. METHODS AND RESULTS...

Atrial fibrillation is the most common sustained arrhythmia. Because of its potentially serious clinical consequences (heart failure, stroke, and cognitive impairment), atrial fibrillation has important socioeconomic and health implications. This article reviews the major studies on the epidemiology of atrial fibrillation in Spain. Recent data suggest that in people older than 40 years, the pre...

INTRODUCTION AND OBJECTIVES The impact of atrial fibrillation on the prognosis of myocardial infarction is still the subject of debate. We analyzed the influence of previous and new-onset atrial fibrillation on in-hospital and long-term prognosis in patients with acute myocardial infarction. METHODS Prospective study of 4284 patients with ST-segment elevation acute myocardial infarction. We s...

Mechanisms regulating stretch response in the left ventricle are investigated in detail but not well understood in atrial myocardium. Hypertrophic growth of atrial myocardium contributes to the pathogenesis of atrial fibrillation. In this study, we sought to elucidate mechanisms of stretch-induced activation of key signaling pathways and hypertrophy-associated genes in rat atria. Stretching of ...

We appreciate the comments of Drs Aihara and Guyatt on our study, 1 but before replying to them, we would like to correct an erratum in our study. The p-value for the difference in event rates among 3 groups with different risk levels who had not been given warfarin (Non-warfarin group) should be 0.053 instead of 0.048 after 1 point was given to those with hypertrophic cardiomyopathy (Table 31)...
