AIMS To test the hypothesis that echocardiographic tissue Doppler imaging (TDI) reveals reduced myocardial function in hypertension, diabetes, and ischaemic heart disease (IHD) in the general population. METHODS AND RESULTS Within a large, community-based population study, cardiac function was evaluated in 1036 participants by both conventional echocardiography and colour TDI. Peak systolic (...

BACKGROUND Tissue Doppler imaging (TDI) detects left ventricular dysfunction in patients with heart failure and normal ejection fraction, but the prognostic significance of left ventricular dysfunction by TDI in the general population is unknown. METHODS AND RESULTS Within the Copenhagen City Heart Study, a large community-based population study, cardiac function was evaluated in 1036 partici...

OBJECTIVE To examine the relation between longitudinal left ventricular function assessed by tissue Doppler imaging (TDi) and exercise capacity in heart failure. SUBJECTS 153 patients with chronic heart failure from left ventricular systolic dysfunction (ejection fraction < 45%) and 87 age and sex matched controls. METHODS Echocardiography was used to measure conventional indices of left ve...

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

The aim of the study was to determine whether segmental interactions, as expressed by postsystolic shortening (PSS), affects RV mechanics and are connected with impaired systolic and diastolic function in rTOF children. PATIENTS AND METHODS 55 rTOF adolescent (study group), and 34 healthy volunteers (control group) were examined using classical Doppler flow (Doppler), Tissue Doppler Imaging (...

BACKGROUND In human medicine, right ventricular (RV) functional parameters represent a tool for risk stratification in patients with congestive heart failure caused by left heart disease. Little is known about RV alterations in dogs with left-sided cardiac disorders. OBJECTIVES To assess RV and left ventricular (LV) function in dogs with myxomatous mitral valve disease (MMVD) with or without ...

EDITORIAL Myocardial dysfunction in sepsis is a complex entity due to the dynamic adaptation of the cardiovascular system to the disease process, the host response, and the effects of resuscitation. The pathophysiology of this entity is multifactorial; systemic, cellular, and extracellular mechanisms have been described, including maldistribution of coronary blood flow, myocardial injury, compl...

OBJECTIVE To determine prospectively whether interatrial dyssynchrony detected by tissue Doppler imaging (TDI) is useful for predicting the progression to chronic atrial fibrillation (CAF) in patients with non-valvular paroxysmal AF (PAF). METHODS Thirty-seven patients with non-valvular PAF were prospectively followed after echocardiography. The interval of time from initiation of the P wave ...

BACKGROUND Cardiac resynchronization therapy has been shown to improve systolic function in patients with advanced chronic heart failure and electromechanical delay (QRS width > 120 ms). However, the effect of acute biventricular (BiV) pacing on perioperative haemodynamic changes is not well defined. In the present study, acute changes in regional left ventricular (LV) systolic function determi...

Introduction: Assessment of diastolic heart function can be challenging due to various factors. Doppler echocardiography is useful but has limitations, pointing the need for more accurate tests. Tissue imaging (TDI) a promising ultrasound technique prediction. The E/E' ratio commonly used determine LV filling pressures. B-natriuretic peptide (BNP) levels may also indicate dysfunction. Aims: To ...
