Abstract:

Recentemente Tei e collaboratori, hanno proposto un nuovo indice Doppler-derivato in grado di valutare simultaneamente la funzione sistolica e diastolica. Questo indice di performance cardiaca (MPI), definito come la somma del tempo di contrazione isovolumetrica e tempo di rilasciamento isovolumetrico diviso per il tempo di eiezione ventricolare sinistro, è considerato di facile esecuzione, non dipendente dalla geometria ventricolare, non invasivo, riproducibile e indipendente dalla frequenza cardiaca e dalla pressione arteriosa.

Abstract:

The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function. Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia. We evaluated the diagnostic sensitivity and specificity of pulsed tissue Doppler for the detection of ischemia and scar during dobutamine stress testing and compared it with myocardial perfusion scintigraphy (SPECT) in pat

Abstract:

The projects of this thesis examine the complex interaction between isotonic exercise, functional capacity, exercise-induced myocardial ischaemia, severity of regurgitation and left ventricular function in patients with significant chronic mitral regurgitation. The concept of left ventricular contractile reserve, i.e. the ability of the left ventricle to increase its contractility and decrease its end systolic volume with isotonic exercise, is explored. In patients with chronic isolated mitral regurgitation without coronary disease, isotonic exercise was associated with a slight decrease in le

Abstract:

Increasingly, diagnosis of cardiac disease, relies on computer processing of images to aid decision making. In this thesis, we use echocardiography, which is the most widely used cardiac imaging modality to study the motion of the left ventricle. Currently, clinical reporting of echocardiography examinations is operator-dependent and largely qualitative. Commercially available software does not track the left ven- tricle. Also, it does not provide quantification of regional function. This thesis establishes a framework for the quantitative regional analysis of left ven- tricular function. The

Abstract:

Chronic mechanical load variation triggers a wide range of responses in the heart, a part of which includes cellular remodelling. Over the past 15 years, evidence has amassed that a part of this remodelling process involves changes to a sophisticated structure in the cell membrane, called the transverse (t)-tubule system. The t-tubules are a series of regular membrane invaginations, which contain a high density of ion channels responsible for local Ca2+ induced Ca2+ release (CICR). This thesis addresses the question of whether the t-tubule system can be said to be specifically load sensitive,

As a result, it has been proposed that LV diastolic dysfunction is the primary pathophysiological process in HF-PSF.

Background: Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV).

Thus, lifelong follow-up of these patients is required. Echocardiography is the most patient’s friendly method to evaluate CoA and in particular its effect on LV function.

Abstract:

This study examines the α-adrenergic constrictor tone varies with intensity of exercise, the effects of coronary α1-adrenergic blockade on left ventricular contractile function and regional myocardial perfusion, and compares the effects of increasing coronary blood flow by removing α1-constrictor tone.

Abstract:

Myocardial wall stress (MWS) is a crucial factor linked to myocardial hypertrophy, which can lead to heart failure, particularly heart failure with preserved ejection fraction (HFpEF). Shortening-deactivation of cardiac myocytes could provide a mechanism linking systolic to diastolic dysfunction whereby an impairment of early systolic ejection leads to sustained myocardial contraction, preserving overall ejection fraction at the expense of diastolic dysfunction. We formulated a novel index of first phase ejection fraction (EF1), the fraction of left ventricular volume ejected from the start of
