BACKGROUND: Although an enlarged left atrium has recently emerged as a marker of adverse outcomes in various diseases, its discriminatory value and prognostic role in acute ischemic stroke (AIS) are not well studied. We studied whether left atrial volume index (LAVI) predicts mortality and discriminates stroke subtypes after AIS. METHODS: We prospectively followed 310 consecutive first-ever AIS patients aged 50 years or older who were admitted to the hospital within 24 hours of the onset of stroke symptoms...

BACKGROUND: Left atrial (LA) compliance and contractility influence left ventricular stroke volume. We hypothesized that diminished LA compliance and contractile function occur early during the development of heart failure with preserved ejection fraction (HFpEF) and impair overall cardiac performance. METHODS AND RESULTS: Cardiac magnetic resonance imaging, echocardiography, left ventricular and LA pressure-volume studies, and tissue analyses were performed in a model of early HFpEF (elderly dogs, renal wrap-induced hypertension, exogenous aldosterone; n=9) and young control dogs (sham surgery; n=13)...

BACKGROUND AND PURPOSE: Left atrial dysfunction has been reported in patients with patent foramen ovale (PFO). Here we investigated the role of left atrial dysfunction in the development of embolic stroke in patients with PFO. METHODS: We identified consecutive patients with embolic stroke of undetermined sources except for PFO (PFO+ESUS). Healthy subjects with PFO served as controls (PFO+control). A stratified analysis by 10-year age group and an age- and sex- matching analysis were performed to compare echocardiographic markers between groups...

INTRODUCTION: Left atrial (LA) enlargement is an important risk factor for incident stroke and a key determinant for the success of rhythm control strategies in patients with atrial fibrillation (AF). However, factors associated with LA volume in AF patients remain poorly understood. METHODS: Patients with paroxysmal or persistent AF were enrolled in this study. Real time 3-D echocardiography was performed in all participants and analyzed offline in a standardized manner...

Cardiac changes in athletes involve the left ventricle and atrium. Mild left atrial enlargement is common among competitive athletes, possibly a physiologic adaptation to exercise conditioning. The prevalence of this remodeling and the association with supraventricular arrhythmias has not been systematically addressed. Echocardiography screens for patients with disease involving the left atrium. New techniques like speckle tracking can recognize early atrial dysfunction and assess left atrial myocardial function in patients with either physiologic or pathologic left ventricular hypertrophy...

BACKGROUND: The hypertensive deoxy-corticosterone acetate (DOCA)-salt-treated pig (hereafter, DOCA pig) was recently introduced as large animal model for early-stage heart failure with preserved ejection fraction (HFpEF). The aim of the present study was to evaluate cardiovascular magnetic resonance (CMR) of DOCA pigs and weight-matched control pigs to characterize ventricular, atrial and myocardial structure and function of this phenotype model. METHODS: Five anesthetized DOCA and seven control pigs underwent 3 T CMR at rest and during dobutamine stress...

Although central obesity is a more powerful predictor of cardiovascular disease (CVD) than general obesity, there is limited information on structural and functional changes of the heart in central obesity. Therefore, we evaluated the association between abdominal obesity and geometric and functional changes of the heart in healthy males. A total of 1460 healthy males aged 40 to 70 years without known CVD from the Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population were included...

: Aims The pathophysiological entity of a persisting left-sided superior caval vein draining into the roof of the left atrium represents an extreme form of coronary sinus de-roofing. This is an uncommon, but well-documented condition associated with systemic desaturation due to a right-to-left shunt. Depending on the size of the coronary ostium, the defect may also present with right-sided volume loading. We describe two patients, both of whom presented with desaturation, and highlight the important anatomical features underscoring management...

OBJECTIVE: Hemangiomas are tumors most commonly encountered in pediatric patients, and are frequently treated with propranolol. However, there are currently no standard methods for evaluating cardiac function in patients prior to propranolol treatment. The present study was designed to aid in the evaluation of pretreatment cardiac and effects of propranolol on vital signs in pediatric hemangioma patients. METHODS: A pediatric oncology specialist and a pediatric cardiology specialist examined all patients prior to initiation of propranolol treatment...

BACKGROUND: Aortic valve replacement (AVR) for chronic aortic regurgitation (AR) with a decreased ejection fraction (EF) leads to improvement in left ventricular (LV) function, but there are no reports on late recurrence of LV dysfunction over long-term after AVR. This study aimed to identify frequency and predictors of late recurrent LV dysfunction after AVR. METHODS: We retrospectively investigated 58 consecutive patients undergoing AVR for severe chronic AR and with follow-up echocardiography for >5years after AVR...

BACKGROUND: We aimed to identify the predictors of clinical outcomes after circumferential pulmonary vein isolation (CPVI) without any substrate modification for long-standing persistent atrial fibrillation (LSP-AF). METHODS: This study retrospectively analyzed 70 consecutive LSP-AF patients who underwent an initial CPVI and were followed up for more than one year. The right and left atrial volumes indexed to the body surface areas (RAVI and LAVI) were determined by pre-acquired contrast-enhanced computed tomography (CT)...

BACKGROUND: Alcohol consumption has been associated with atrial fibrillation (AF) in several epidemiologic studies, but the underlying mechanisms remain unknown. We sought to test the hypothesis that an atrial myopathy, manifested by echocardiographic left atrial enlargement, explains the association between chronic alcohol use and AF. METHODS AND RESULTS: We evaluated the relationship between cumulative alcohol consumption and risk of incident AF in 5220 Offspring and Original Framingham Heart Study participants (mean age 56...

UNLABELLED: Heart failure with preserved ejection fraction occurs almost with the same frequency as heart failure with reduced ejection fraction. The diagnosis is based on echocardiography with evidence-based ejection fraction over 50 %, or with left atrial enlargement and left ventricular hypertrophy, and specification of natriuretic peptides. BNP 35 pg/ml and NT-proBNP 125 pg/ml are considered the limits of the norm for chronic heart failure. The treatment of heart failure with preserved ejection fraction lacks clear evidence of mortality reduction, diuretics are recommended to remove symptoms, ACE inhibitors or sartans and beta-blockers to improve the prognosis...

OBJECTIVE: CHA2DS2-VASc score, left atrial (LA) size and atrial fibrillation (AF) have individually been associated with stroke risk. Our aim was to investigate the predictive ability of combinations of these factors for the odds of incident stroke in a population-based cohort study. METHODS: We followed 2844 participants from the Tromsø Study from 1994 to 2012. Information on LA size and CHA2DS2-VASc score (age, sex, congestive heart failure, hypertension, vascular disease, stroke and diabetes) were obtained at baseline...
