..Patient selection, often restricted to those with ideal image quality, and timing of studies in relation to reference methods may limit clinical applicability of cardiac volumes derived from 3D echocardiography...

..This calculation is known to be inaccurate with serum triglyceride (TG) concentrations >4.52 mmol/l, however, its accuracy among relatively healthy patient cohorts with TG concentrations < or =4.52 mmol/l is less well studied...

..The aim of the current case-control study was to use speckle tracking imaging to identify subclinical global and regional systolic function abnormalities in hypertensive subjects with normal ejection fraction...

..The purpose of this study was to evaluate trends in the use of ventriculography and echocardiography to measure EF in a community sample of patients hospitalized with AMI...

....

..63) and improved when patients with liver or pulmonary disease were excluded (r = 0.83). In conclusion, PASP strongly correlated with PAWP, and this principle can be exploited to rapidly detect patients with low or high PAWP...

....

..In conclusion, almost 1/3 of patients hospitalized with diastolic HF had systolic dysfunction, characterized by abnormal midwall stress-shortening relations...

....

..The purpose of this study was to assess the concordance between echocardiography and CVG for the determination of EF in routine clinical practice and to identify factors associated with variation in test results...

..Approximately three-fourths of the oldest patients were women, and two-thirds of women had a left ventricular ejection fraction >or=50%...

..The mechanism of the paradoxical increase in BNP is not entirely clear, but it may conceivably be a result of counterregulatory hormone release caused by acute decrease in blood pressure...

..Despite the development of repolarization abnormalities and QT prolongation in SCM, little is known about the risk of ventricular fibrillation (VF) and TdP...

..Aortic root diameter, relative wall thickness, heart rate, heart rhythm, cardiac output, presence or severity of coronary artery disease, and time interval between studies were not predictors of discrepant results...

..Our goal was to determine if strain measures [peak systolic longitudinal strain (LAS) and stiffness index (LASt)] changed after cardioversion (CV); and their relation to AF recurrence...

....

..The study objectives were to monitor trends in HR and BP in relation to beta-blocker use in a contemporary series of patients with ACS...

..CONCLUSIONS: The rapid fall in BNP after cardioversion (1) may reflect prompt hemodynamic improvement associated with rhythm change and (2) does not appear to be due to the effects of sedation...

..This article reviews clinical aspects of the syndrome, its recognition by echocardiography, and will review other disorders whose recognition is due primarily to the availability of echocardiography...

..It is likely that the widespread use of echocardiography, coupled with increased recognition of this syndrome, will result in this diagnosis being made more commonly...

..She was found to have stenosis of all four pulmonary veins and severe pulmonary hypertension. We describe the echocardiographic findings and review the literature on assessment of acquired pulmonary vein stenosis...

..This article focuses on reviewing contemporary data as it pertains to AF management in patients with HF and provides insight into investigational therapies currently under development...

..Symptoms, electrocardiogram (ECG) findings, and the spectral Doppler abnormalities resolved completely following a generator replacement and resumption of DDDR pacing...

..We utilized STI to analyze LA function in diastolic dysfunction (DD), hypothesizing that LA strain abnormality is part of the pathogenesis of diastolic dysfunction...
