Effetti cardiotossivi precoci e tardivi del trattamento con Epirubicina. Valutazione con marker biochimici ed ecocardiografia Tissue Doppler.
… conventional echocardiography, as well as tissue Doppler imaging (TDI) with Strain (ε) and Strain Rate (SR). Moreover, echocardiographic changes identified during the Epi treatment were compared with inflammatory and oxidative stress laboratory markers. Thirty-one patients (age 59±14 yrs) …

The impact of morbid obesity on cardiac structure and function in pregnancy
… vs 61 [15] milliseconds, P<0.001). The septal tissue Doppler index E' sept was lower in Group O (9.08 [1.69] vs 11.28 [3.18], P<0.001). There were no between- group differences in E' average (10.7 [2.3] vs 12.0 [2.7], P=0.018), or E/E' average (7.85 [1.77] vs 7.27 [1.68]). Conclusion: Obese …

Application of remote ischaemic preconditioning to human coronary artery bypass surgery
… M mode, 2D contrastenhanced echocardiography and tissue Doppler imaging) or offer antiarrhythmic benefit (de novo left bundle branch block or Q waves; ventricular tachyarrhythmia incidence). RIPC did not afford renal (peak creatinine, AUC urinary albumin-creatinine ratios, dialysis requirement) or …

Clinical assessment of arterial stiffness
… were to investigate the reproducibility of a tissue Doppler imaging (TDI) based ultrasound system to calculate indices of arterial stiffness, and to investigate changes in arterial wall stiffness in subjects with increased age, peripheral arterial disease (PAD), chronic kidney disease (CKD) …

Left Ventricular Long Axis Dynamics in Pathological and Physiological Left Ventricular Hypertrophy
… annulus, such oscillations may be measured using tissue Doppler echocardiography (TDE). During systole the annulus descends and during early diastole (E<sub>TDE</sub>) and atrial systole (A<sub>TDE</sub>) it ascends. This thesis examined whether changes in the velocity of the annulus in each of …

Responding to resynchronization : improving the impact of biventricular pacing in the management of chronic heart failure
… Chapter 3 investigates the role of pulsed-wave tissue Doppler echocardiography as a means of assessing myocardial dyssynchrony in a prospective group of patients referred for CRT. It is shown that the degree of dyssynchrony will differ depending on the model employed to determine it. Chapter 4 …

New methods for quantifying the synchrony of contraction and relaxation in the heart
… The first method improved upon existing tissue-Doppler based echocardiographic diagnosis of dyssynchrony by utilizing a cross-correlation (XC) function to quantify dyssynchrony during post-processing as opposed to the quantitatively simplistic time-to-peak analysis that is currently …

Improving Cardiovascular Risk Assessment with CT Coronary Angiography and Myocardial CT Perfusion
… examined utilizing both high temporal-resolution tissue Doppler imaging and CT. The period of mid-diastole was found to occur relatively later in the cardiac cycle with increasing heart rate. The study demonstrated the importance of heart rate control and precise timing in cardiac imaging. The …

Left Ventricular Diastolic Function in Adolescents with Overweight and Obesity: The Moderating Influence of Physical Activity, Cardiorespiratory Fitness, and Metabolic Health
… impairments were best demonstrated by septal tissue-Doppler imaging (TDI) methods of echocardiography (z-score difference=0.91; 95% CI=0.46, 1.37). This study also identified preliminary evidence for links of insulin resistance (IR) and CRF with LVDF, but there were no studies to address the …

The genetics of anthracycline-induced cardiotoxicity in cancer patients
… of alternatives such as echocardiography or tissue-doppler imaging. Findings derived from this study indicate the need for refined patient management of ACT in a South African population to potentially allow for treatment with minimised risk and event-free breast cancer survival.
