..The incidence and risk associated with new-onset atrial fibrillation (AF) occurring after discharge in patients with acute myocardial infarction (MI) remains unknown...

..Thus, patients with nonsustained VT should undergo careful investigation, and we recommend a repeat echocardiography and electrophysiological stimulation in these patients. Patients with sustained VT or VF should receive an ICD...

..Hypertension is a common comorbidity in patients with heart failure and may contribute to development and course of disease, but the importance of a history of hypertension in patients with prevalent heart failure remains uncertain...

..Patients suspected of acute pulmonary embolism (PE) frequently undergo echocardiography as a part of the initial work-up. Prognostic implication of routine echocardiography in patients suspected of PE remain to be established...

..Left ventricular diastolic dysfunction (DD) is common after myocardial infarction (MI) despite preservation of left ventricular ejection fraction, yet it remains unclear how or whether DD affects cardiac hemodynamics with stress...

..IVA is believed to be less dependent on preload than previously proposed estimates. IVA has been measured at different locations, and studies have shown conflicting results...

..The purpose of the present study was to determine the prognostic importance for all-cause mortality of lung function variables obtained by spirometry in an unselected group of patients admitted with heart failure (HF)...

..aureus IE (p =0.05). In conclusion, CoNS IE was associated with a long diagnostic delay and high in-hospital mortality, whereas post-discharge prognosis was better in this group of patients compared to patients with IE due to S. aureus...

..These findings emphasize the potential role of exercise echocardiography in studying exercise hemodynamics in LVAD patients...

....

..This study evaluated the relation of size of perfusion defects and changes in echocardiographic measures of global and regional RV dysfunction in 58 consecutive patients with non-massive PE...

....

..We performed a combined evaluation of LV function and RF for prognosis in patients with HF with and without systolic dysfunction...

..Diabetes mellitus (DM) in combination with heart failure (HF) is associated with a high risk of death, but it is uncertain whether the prognosis differs in ischemic and non-ischemic HF groups...

..Three-dimensional echocardiography and Doppler tissue imaging (DTI) are new echocardiographic modalities for the evaluation of global and regional function, but the diagnostic potential remains to be assessed...

..Tricuspid annular plane systolic excursion (TAPSE) is a simple echocardiographic measure of RV ejection fraction, but may be affected by co-existing chronic obstructive pulmonary disease (COPD)...

..However, no studies have assessed the interrelation of PALS and left ventricular longitudinal strain (global longitudinal strain) in large-scale populations in regard to prognosis...

..However, many patients develop HF despite preserved LV ejection fractions. The aim of this study was to test the hypothesis that LV longitudinal function is a stronger marker of in-hospital HF than traditional echocardiographic indices...

..Heart failure (HF) is increasingly prevalent among the growing number of elderly people, but not well studied. We sought to evaluate disease pattern and importance of prognostic factors among very elderly patients with HF...

..The objective of this study was to investigate the outcome of surgical treatment and to validate the ability of euroSCORE to predict operative mortality in NVE patients...

..The significant changes in filling pattern and IVRT in the setting of normal and unchanged systolic function, indicates that hypoxia induces mild diastolic dysfunction in young healthy individuals...

..However, little is known about the relationship between longitudinal deformation indices and NT-proBNP...

..But the underlying mechanisms of the refractory arrhythmias are not well understood...

..We describe the determinants of exercise-induced changes in MR in patients with non-ST-elevation acute coronary syndrome (NSTACS)...

....

..Percutaneous mitral valve repair with the MitraClip system resembles the Alfieristitch where a clip is used to connect the tip of the mitral valve leaflets...

..Most studies have excluded patients with atrial fibrillation. The aim of the present study was to assess the prognostic value of a restrictive filling pattern in patients with atrial fibrillation...

..In the present study, we prospectively evaluated the importance of screening with echocardiography in an unselected S. aureus bacteraemia (SAB) population...

..Mutations within several genes are HH-associated, the most common being the HFE gene. In a large cohort of HF patients, we sought to determine the etiological role and the prognostic significance of HFE genotypes...

..We compared LVOT gradients induced by Valsalva manoeuvre (VM) and exercise echocardiography (EE) in patients with HCM treated with percutaneous transluminal septal myocardial ablation (PTSMA)...

..Evidence supporting partial oral therapy as an alternative to the routinely recommended continued parenteral therapy is scarce, although observational data suggest that this strategy may be safe and effective...

..The impact of heart failure (HF) etiology on prognosis of HF is not well known...

..Several quantitative echocardiographic measures of global and regional right ventricular (RV) function have been proposed, but knowledge of the impact of increases in preload and afterload is limited...

..We wanted to test whether murmur predicts mortality in unselected patients admitted to the hospital and whether NT-pro-BNP is capable of distinguishing between innocent and significant murmurs...

..The aim of this study was to quantify the nephrotoxic effect of gentamicin and the association between the nephrotoxic effect and mortality in patients with IE...

..The aim of this randomized study was to investigate the effects of once versus twice daily gentamicin dosing on renal function and measures of infectious disease in a population with infective endocarditis (IE)...

..Mitral regurgitation (MR) secondary to ischemic heart disease (IHD) increases during exercise. We tested the hypothesis that the same is also true for MR due to mitral valve prolapse (MVP)...

..Furthermore, LA volume is related to AVA even when adjusting for other known risk factors for increased LA volume including of measurements of diastolic function...

..A number of complicating conditions are known to be of importance for the outcome. But only few data are available in IE patients on the independent prognostic value of kidney function at the time of admittance...
