Abstract
Abstract
Background
Angiotensin receptor-neprilysin inhibitor (ARNI) is a cornerstone of treatment in heart failure (HF) with reduced ejection fraction (HFrEF), but its effectiveness shows interindividual differences.
Objectives
To evaluate the predictive value of echo-derived hemodynamic forces (HDF), together with other echocardiographic, biohumoral and cardiopulmonary parameters on a) response to ARNI after 6 months; b) adverse cardiovascular events at follow-up.
Methods
Eighty-nine consecutive HFrEF patients from two HF centers performed clinical evaluation, laboratory analyses, rest echocardiography and cardiopulmonary exercise testing. Response to ARNI at 6 months was considered in patients without HF admissions, death, or urgent heart transplant and with a ≥50% reduction in NT-proBNP levels and/or ≥10% increase in left ventricle ejection fraction. After 6 months, patients were followed up for a composite endpoint of cardiovascular death, HF-related hospitalization and new-onset atrial fibrillation.
Results
Response to ARNI was documented in 45/89 (51%) of patients. At baseline, responders and non-responders were paired in clinical assessment, conventional echocardiography, functional status and therapy. At multivariate logistic regression analysis, HDF-derived whole cardiac cycle left ventricle strength (wLVS) was the only independent predictor of ARNI response at 6 months (odds ratio 1.36, 95% confidence interval 1.10–1.67; p=0.004). A wLVS ≥3.7% showed a good accuracy in predicting ARNI response (AUC = 0.736, 0.607–0.840; p<0.0001). During a median of 33 (IQR 23–41) months, wLVS increase from baseline to 6-month (ΔwLVS) showed a high discrimination ability at time-dependent ROC analysis (optimal cut-off: ≤0.5%; AUC=0.811, 0.69–0.90; p<0.0001), stratified prognosis at Kaplan-Meier analysis (log-rank p<0.0001), and remained an independent prognostic predictor of the composite endpoint (hazard ratio 0.76, 0.61–0.95; p<0.01) even after adjusting for clinical, functional and conventional echocardiographic parameters.
Conclusions
HDF analysis may help predict ARNI response and optimize follow-up and medical/device strategies in patients with HfrEF.

Background
Sport induces structural and functional cardiac adaptation with different entity related to several factors including type of training and gender. Cardiovascular Magnetic Resonance (CMR) is the gold standard for morpho-functional evaluation of athletes’ heart and commonly relies on ventricular volume, wall thickness and ejection fraction (EF) assessment. Data on myocardial deformation (MD) are limited to echocardiography and are scarce.
Purpose
To assess MD in Olympic athletes and to evaluate the possible influence of sport categories and gender.
Methods
A group of Olympic athletes evaluated prior the Olympic games with unremarkable cardiovascular pre-participation screening tests underwent CMR without contrast administration. A group of sedentary subjects was enrolled as a control group. Cine-images were post-processed for volume and function evaluation and to assess global longitudinal strain (GLS) and global circumferential strain (GCS) by feature-tracking software. Athletes were divided in subgroups according to ESC sport classification. Male and female athletes were compared. Athletes were also divided based on EF (≤53% or >53%).
Results
93 elite athletes (33% power, 33% mixed, 33% endurance) and 18 controls were enrolled. No differences in terms of EF were observed, while endurance athletes showed the greater LV remodeling (Table). GLS and GCS values of the entire population were -22.5±2.7% and -30.7±3.4%, respectively. No significant differences were found comparing athletes of different sport categories and sedentary controls for GLS (p= 0.940) and GCS (p=0.072). Female athletes showed higher GLS compared to male (-23.5±2.8% vs-21.9±2.8%, p=0.002) but not differences in terms of GCS (-31.5±3.1% vs-30.2±3.5%, p=0.076). Athletes with EF≤53% had lower GLS values compared with those with >53% but within normal limits (Figure).
Conclusion
No differences were observed in MD assessed by CMR between different sport categories and controls. Female athletes showed higher longitudinal but not circumferential strain compared with male. Athletes with lower EF presented lower values of strain but within normal range with the potentiality to be used as a tool for differential diagnosis between normal adaptation and disease.

Background
Non-invasive evaluation of left ventricular hemodynamic forces (HDFs) by Cardiac Magnetic Resonance (CMR) is a promising tool to improve systolic and diastolic evaluation. No data are available on athletic population.
Purpose
To provide the range of normal values of HDFs in Olympic athletes and to evaluate the possible influence of different sport categories.
Methods
A group of Olympic athletes evaluated prior the Olympic games with unremarkable cardiovascular pre-participation screening tests underwent CMR without contrast administration. A group of sedentary subjects was enrolled as a control group. Cine-images were post-processed by a feature-tracking based software to estimate HDFs. HDFs were measured in apex-base (AB) and latero-septal (LS) directions, over the entire heartbeat, in systole and diastole. Athletes were divided in subgroups according to ESC sport classification for comparison. They were also divided according to the ejection fraction (EF ≤ or >53%).
Results
93 elite athletes (33% power, 33% mixed, 33% endurance) were enrolled. HDFs in AB and LS direction were 20.5%± 4.3 and 2.9%± 0.7 in the entire heartbeat, 32.6% ± 7 and 3.6%± 1 in systole, 11%± 4.1 and 2.3%± 0.8 in diastole. Comparing athletes of different sport category and sedentary controls no significant differences were found between groups (Table). Comparing athletes with ejection fraction (EF) £ 53% and > 53%, the former showed lower values of AB-HDFs assessed in the entire heartbeat and in systole (18.9 ± 4.6 % vs 20.9 ± 4.1; p= 0.024 and 29.6 ± 6.3 vs 33.3 ± 7; p= 0.024, respectively), but within the normal range.
Conclusion
We provide normal range for HDFs assessed by CMR in elite athletes and no differences were observed between sedentary controls and athletes involved in different sport categories. Comparing athletes with low-normal and normal ejection fraction, the former showed lower values of AB-HDFs but within the normal range.

Abstract
Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
Sacubitril/valsartan (S/V) benefits in patients with heart failure and reduced ejection fraction (HFrEF) are partially related to cardiac reverse remodelling, in terms of volumes reduction and function improvement. Effects on vascular remodeling are less investigated.
Purpose
To evaluate cardiac and vascular remodelling in a cohort of patients with HFrEF after six months of therapy with S/V.
Methods
50 patients with HFrEF eligible to start a therapy with sacubitril/valsartan were enrolled. Clinical evaluation and standard and advanced echocardiography were performed at baseline and after six months of follow up (FU). Standard left ventricular dimension and function parameters, global longitudinal strain (GLS) were calculated. Non-invasive pressure-volume curves (P-V loop) estimation was assessed with an off-line dedicated software using ST-E derived time-resolved LV volumes and brachial pressure as input. The following hemodynamic parameters were calculated based on P-V loop curves: left ventricular elastance (Ees), arterial elastance (Ea) and ventricular-arterial coupling (VAC).
Results
At six months F/U, a reduction of NYHA class in the vast majority of patients was detected (NYHA Class ≥ II, baseline vs F/U = 100% vs 50%; p< 0,001). Systolic and diastolic blood pressure were lower, in comparison with baseline values (119 ± 16 vs 126 ± 11 mmHg; p = 0,002 and 71 ± 8 vs 78 ± 8 mmHg; p = 0,001, respectively). At echocardiographic evaluation, left ventricular end-diastolic and end-systolic volumes decreased (p< 0.001 and p< 0,001, respectively) and ejection fraction and GLS significantly improved (p< 0.001 and p < 0.001, respectively). Moreover, a significant reduction of Ea and a significant improvement of Ees and VAC were observed (p = 0.008, p< 0,001 and p< 0,001, respectively).
Conclusion
Therapy with S/V in HFrEF patients determines both cardiac and vascular remodelling reflecting the complex mechanisms behind clinical improvement. Abstract Figure.

Background
Hemodynamic forces (HDFs) are the forces exchanged between the blood and the myocardium. Estimation of their magnitude and alignment could be a novel marker of cardiac dysfunction.
Purpose
To describe left ventricular (LV) HDFs values and distribution in patients with heart failure with reduced ejection fraction (HFrEF) and to compare them with those of a group of healthy controls.
Methods
A cohort of 26 non-ischemic patients with an initial diagnosis of HFrEF was enrolled. All of them underwent basal 2D echocardiography evaluation. Off-line HDFs estimation using a dedicated software based on speckle-tracking echocardiography was conducted. HDFs were normalized for the LV volume and expressed as a percentage of the force of gravity. HDFs were assessed over the entire cardiac cycle, in systole and diastole, both in apex to base (A-B) and latero-septal (L-S) directions. The distribution of LV HDFs was evaluated by L-S over A-B HDFs ratio (L-S/A-B HDFs ratio). HDFs of HFrEF patients were compared with those of 24 healthy volunteers.
Results
HFrEF patients showed smaller values of A-B HDFs during the entire cardiac cycle (5,2 ± 1,24% vs 12,3 ± 3,6%; p = 0,001), in systole (7,2 ± 2% vs 16,6 ± 6,3%; p = 0,001) and diastole (3,3 ± 0,8% vs 7,1 ± 3,6%; p = 0,001). Moreover, comparing HFrEF subjects with healthy volunteers , the former had lower L-S HDFs during the entire cardiac cycle (1,6 ± 0,4% vs 2 ± 0,7%; p= 0,022) and in systole (1,6 ± 0,5% vs 2,3 ± 0,8%; p = 0,003), while in diastole they showed inappropriate high values of L-S HDFs (1,7 ± 0,6% vs 1,8 ± 0,9%; p = 0,999). Consequently, HFrEF patients had higher values of L-S/A-B ratio during the entire cardiac cycle (32 ± 6,9 vs 15 ± 7,7; p = 0,001), in systole (23,5 ± 7,4 vs 14,7± 4,2; p = 0,001), but particularly in diastole (52 ± 10,8 vs 28 ± 13,6; p = 0,001), showing an important HDFs misalignment.
Conclusion
When compared with healthy controls, HFrEF patients presented intraventricular fluid alterations characterized by lower HDFs magnitude and a significant HDFs misalignment, especially in diastole. Further studies are needed to confirm these initial results and to assess the effects of therapy on these new parameters. Abstract Figure. Abstract Figure.

Background
Infarct size (IS), area at risk (AAR) and microvascular obstruction (MVO) are well known predictors of adverse remodeling (aLVr) following acute myocardial infarction, while the pathogenic role of left ventricular (LV) hemodynamic forces (HDFs) is still unknown. Recent evidence suggests the role of HDFs in negative remodeling after pathogenic events.
Purpose
To identify LV HDFs patterns associated with aLVr in reperfused ST-segment elevation MI (STEMI) patients.
Methods
Forty-nine acute STEMI patients underwent CMR at 1 week (baseline) and 4 months (follow-up) after MI. The following parameters were measured: left ventricular end-diastolic and end-systolic volume index for body surface area (LVEDVi and LVESVi), left ventricular ejection fraction (LVEF) and LV mass index, AAR and IS. LV HDFs were computed at baseline from cine CMR long axis datasets using a novel method based on LV endocardial boundary tracking. LV HDFs were calculated both in apex-base (A-B) and latero-septal (L-S) directions. The distribution of LV HDFs were evaluated by L-S over A-B HDFs ratio (L-S/A-B HDFs ratio %). All HDFs parameters are computed over the entire heartbeat, in systole and diastole. aLVr was defined as an absolute increase in LVESV of at least 15% (ΔLV-ESV ≥15%).
Results
Patients with aLVr (n = 18; 37%) had significant greater value of AAR (32 ± 23 vs 22 ± 18; p = 0.03) and slightly larger IS (23 ± 16 vs 15 ± 11; p= 0.07) at baseline. In patients with aLVr at FU, baseline systolic L-S HDF were lower (2.7 ± 0.9 vs 3.6 ± 1; p = 0.027) while diastolic L-S/A-B HDF ratio was significantly higher (28 ± 14 vs 19 ± 6; p = 0.03), reflecting higher grade of diastolic HDFs misalignment. At univariate logistic regression analysis, higher IS [Odd ratio (OR) 1.05; 95% confidence interval (95% CI) 1.01-1.1; p= 0.04] L-S HDFs (OR 0.41; 95% CI 0.2-0.9; p= 0.04] and higher diastolic L-S/A-B HDFs ratio (OR 1.1; 95% CI 1.01-1.2; p= 0.05) were associated with aLVr at FU (Table). At multivariate logistic regression analysis, L-S/A-B HDF ratio remained the only independent predictor of adverse LV remodeling after correction for other baseline determinants.
Conclusion
Misalignment of diastolic HDFs following STEMI is associated with aLVr observed after 4 months.

Abstract

Background
Echocardiography has been widely used to study cardiac function in patients with end-stage renal disease on hemodialysis (HD), but cardiac function assessment by measuring cardiac dimensions and their rate of change is load dependent, therefore it is influenced by volume depletion. Effects of acute volume reduction on left (LV) and right ventricular (RV) function are still not well understood. Some studies investigated myocardial mechanics after dialysis using speckle tracking echocardiography (STE) but their relative load-dependency makes STE indices unable to account for changes in pre- and afterload. Myocardial work (MW) incorporates both deformation and load into its analysis and is an emerging tool to study LV myocardial function. There are no data about the effects of hemodialysis on LV MW.
Purpose
This study aimed to evaluate acute changes of novel echocardiographic indices of both LV and RV function after a HD session.
Methods
Patients with end-stage renal disease undergoing HD were prospectively enrolled. A transthoracic echo, including STE calculation of LV global longitudinal strain (GLS) and free wall RV strain, was performed before and after hemodialysis. Parameters of MW such as global work index (GWI), global constructive work (GCW), global work efficiency (GWE) and global wasted work (GWW) were quantified using a commercially available software package.
Results
27 patients were enrolled, mean baseline parameters were: LV end-diastolic volume 136 ± 38 mL, LV ejection fraction (LVEF) 56.9 ± 7.5%, LV GLS -17.1 ± 4.1%, RV free wall strain -26.9 ± 5.6%, GWI 2117 ± 602 mmHg%, GCW 2299 ± 633 mmHg%, GWW 137 ± 88 mmHg, GWE 93 ± 3.6%, systolic arterial pressure 145 ± 26 mmHg and diastolic pressure 80 ± 16mmHg. After hemodialysis we observed a significative reduction in LV GLS (p = 0.04), RV strain (p = 0.002), GWI (p = 0.002, Figure I) and GCW (p = 0.004). No significative changes in LVEF and blood pressure were observed. Comparing patients using a LVEF cut-off of 55% (19 patients with LVEF≥55%, 8 patients <55%) we observed a significative reduction of LV GLS (p = 0.004), GWI (p < 0.001), GCW (p < 0.001) only in patients with LVEF ≥55% while RV strain and LV volume showed a reduction in both groups. We observed no significative differences in extracted volumes between the groups (2.6 vs 2.1 liters,p = 0.3). Patients with normal LVEF showed a significative negative variation (D) of LVEF (-1 vs 3%), GWI (-551 vs 38 mmHg%) and GCW (-522 vs 11 mmHg%). Correlations were found between DGWI and extracted volume (r= 0.46, p = 0.01), basal GWI and both DLVEF (r= 0.39, p = 0.04) and DLV GLS (r= 0,42, p = 0.02), basal LV GLS and DLVEF (r= 0.5, p < 0.01).
Conclusions
Our preliminary data show that, immediately after the HD session, there is a reduction in biventricular STE-derived systolic parameters. Patients with normal LV systolic function are more sensitive to acute volume changes and entity of volume depletion seems to be correlated with MW reduction.

Abstract
Abstract
Background
Dobutamine stress echo (DSE) is a useful tool for the evaluation of patients with suspected stable coronary artery disease (CAD). There has been no detailed investigation about the effects of exercise or pharmacological stress on intraventricular fluid dynamics. The possible association between significant CAD and abnormal fluid patterns has not been studied yet.
Purpose
Aim of the study was to evaluate the intraventricular vortices during dobutamine stress and to find fluid-dynamic patterns associated with the presence of significant CAD.
Methods
36 patients scheduled for coronary angiography (CA) and with clinical indication for DSE for suspected CAD were enrolled. Each patient underwent 2D, 3D and contrast echocardiography for Echo-PIV analysis and vortex quantification, both at rest and at peak stress. Vortex geometric and energetic parameters were evaluated using a post- processional software. Intraventricular pressure gradients were evaluated as well. Positive CA for significant CAD was defined as the presence of at least one epicardial coronary stenosis with ≥70% luminal narrowing.
Result
CA was positive in 58% of patients while DSE in 33%. In the whole population, at peak stress a reduction in vortex area (from 0.36 ± 0.01 to 0.21 ± 0.02; p= 0.001) and in absolute value of vortex intensity (from 0.36 ± 0.1 to 0.26 ± 0.12; p= 0.001) were detected. Vorticity fluctuation and kinetic energy (KE) fluctuation showed a significant increment at peak stress (respectively 0.84 ± 0.17 to 0.93 ± 0.07; p= 0.005; from 1.76 ± 0.37 to 2.47 ± 0.82; p= 0.001), as well as a deviation of flow force momentum angle (φ: from 36 ± 8 to 44 ±9; p= 0.001). Patients with positive CA showed during DSE an higher decrease of the absolute value of vortex intensity (Δ% |vortex intensity| -1.7 ± 0.39 vs -1.3 ± 0.56 vs; p= 0.021), and higher increase of flow force angle (Δ% φ 0.48 ± 0.6 vs 0.1 ± 0.27; p= 0.042). A reversal in the main direction of the vortical flow occurred in 9 patients (25%) at peak stress and 7 of them (64%) were found to have significant right coronary stenosis. This unexpected change in the vortical flow and the presence of right coronary artery stenosis were found significantly associated (X2 p= 0,02). Moreover, patients with circumflex artery stenosis were less likely to have a decrease of vortex length at peak stress (Δ% Vortex length - 0,06 ± 0, 36 vs - 0,34 ± 0,28, p= 0,034).
Conclusion
Significant changes in intraventricular vortices occur during DSE. The presence of significant CAD evaluated with CA was associated with different behavior of fluid dynamics during DSE. Further studies are needed to assess normal and pathological intraventricular flow patterns evaluated during DSE.

Abstract
Background There are still many pendent issues about the effective evaluation of cardiac resynchronization therapy impact on functional mitral regurgitation. In order to reduce the intrinsic difficulties of quantification of functional mitral regurgitation itself, an automatic quantification of real-time three-dimensional full-volume color Doppler transthoracic echocardiography was proposed as a new, rapid, and accurate method for the assessment of functional mitral regurgitation severity. Recent studies suggested that images of left ventricle flow by echo-particle imaging velocimetry could be a useful marker of synchrony. Echo-particle imaging velocimetry has shown that regional anomalies of synchrony/synergy of the left ventricle are related to the alteration, reduction, or suppression of the physiological intracavitary pressure gradients. Case summary We describe a case in which the two technologies are used in combination during acute echocardiographic optimization of left pacing vector in a 63-year-old man, Caucasian, who showed worsening heart failure symptoms a few days after an implant, and the effect of the device’s optimization at 6-month follow-up. Discussion The degree of realignment of hemodynamic forces, with quantitative analysis of the orientation of blood flow momentum (φ), can represent improvement of fluid dynamics synchrony of the left ventricle, and explain, with a new deterministic parameter, the effects of cardiac resynchronization therapy on functional mitral regurgitation. Real-time three-dimensional color flow Doppler quantification is feasible and accurate for measurement of mitral inflow, left ventricular outflow stroke volumes, and functional mitral regurgitation severity. Conclusion This clinical case offers an innovative and accurate approach for acute echocardiographic optimization of left pacing vector. It shows clinical utility of combined three-dimensional full-volume color Doppler transthoracic echocardiography/echo-particle imaging velocimetry assessment to increase response to cardiac resynchronization therapy, in terms of reduction of functional mitral regurgitation, improving fluid dynamics synchrony of the left ventricle.

Abstract
The masseter muscle represents an area of important functional interest. The present study aims to verify the feasibility of ultrasound imaging for quantifying the muscular deformation pattern in the masseter. Fifteen consecutive subjects were enrolled and underwent masseter ultrasound according to a repeatable protocol. Ultrasound was carried out during teeth clenching in natural conditions and after the insertion of a medical device that alters the distance between the dental arches, and was repeated on 3 different days. Results showed that masseter deformation is not uniform within the muscle. The same strain patterns were repeated in the different ultrasounds of the same patient and were modified after the introduction of a medical device. This was supported by quantitative comparisons in the deep portion of the muscle (standard deviation on the three measures: 3% normal conditions, 2% with medical device) showing a systematic reduction with the prosthesis (30% on average). This study demonstrated that masseter strain analysis is a repeatable and sensitive tool for the study of functional analysis of the masticatory organ. This opens new technical perspectives for the diagnosis and therapy of dysfunctional pathologies of the masticatory organ.

Abstract
Metalloproteinases (MMPs) and their endogenous inhibitors (TIMPs), produced in the brain by cells of non-neural and neural origin, including neural progenitors (NPs), are emerging as regulators of nervous system development and adult brain functions. In the present study, we explored whether MMP-2, MMP-9, and TIMP-2, abundantly produced in the brain, modulate NP developmental properties. We found that treatment of NPs, isolated from the murine fetal cerebral cortex or adult subventricular zone, with the clinically tested broad-spectrum MMP inhibitor Marimastat profoundly affected the NP differentiation fate. Marimastat treatment allowed for an enrichment of our cultures in neuronal cells, inducing NPs to generate higher percentage of neurons and a lower percentage of astrocytes, possibly affecting NP commitment. Consistently with its proneurogenic effect, Marimastat early downregulated the expression of Notch target genes, such as Hes1 and Hes5. MMP-2 and MMP-9 profiling on proliferating and differentiating NPs revealed that MMP-9 was not expressed under these conditions, whereas MMP-2 increased in the medium as pro-MMP-2 (72 kDa) during differentiation; its active form (62 kDa) was not detectable by gel zymography. MMP-2 silencing or administration of recombinant active MMP-2 demonstrated that MMP-2 does not affect NP neuronal differentiation, nor it is involved in the Marimastat proneurogenic effect. We also found that TIMP-2 is expressed in NPs and increases during late differentiation, mainly as a consequence of astrocyte generation. Endogenous TIMP-2 did not modulate NP neurogenic potential; however, the proneurogenic action of Marimastat was mediated by TIMP-2, as demonstrated by silencing experiments. In conclusion, our data exclude a major involvement of MMP-2 and MMP-9 in the regulation of basal NP differentiation, but highlight the ability of TIMP-2 to act as key effector of the proneurogenic response to an inducing stimulus such as Marimastat.

Abstract
OBJECTIVES To investigate the effects of sulfur-based spa therapies on oxidation, inflammation and cartilage degradation biomarkers in osteoarthritis (OA) patients. DESIGN AND METHODS Analyses were performed before therapy (T0), after therapy (T1) and 1 month after its suspension (T2), in OA subjects undergoing mud bath treatments in combination (group A) or not (group B) with hydropinotherapy, and compared with those of patients not subjected to spa therapies (group C). RESULTS No modifications in plasma/serum biomarker concentrations were observed throughout the study in non-treated patients, while a significant reduction in oxidation, inflammation and cartilage degradation parameters was evidenced in patients of group A. Group B presented a favorable biochemical profile at T1 but not at T2. CONCLUSIONS To ensure the long term preservation of the chondroprotective effects of sulfur-based therapies, standard mud bath treatments should be associated with hydropinotherapy in order to maintain reduced oxidative, inflammatory and degradative stimuli longer.

Abstract
BACKGROUND Heart abnormalities are frequent findings in patients with acromegaly: systolic abnormalities are considered to be secondary to diastolic changes. AIM The aim of the study was to evaluate whether early systolic abnormalities might be revealed in acromegalic patients using the high sensitive color Doppler myocardial imaging (CDMI) technique. PATIENTS AND METHODS Twenty-two consecutive acromegalic patients with active untreated disease (ACROUNTR) were evaluated at baseline and after a 6-month course with SS analogs (SSa) (ACROSSa); 25 healthy subjects served as controls. All subjects underwent conventional 2D-color Doppler echocardiography, pulse wave tissue Doppler imaging (PW-TDI) and CDMI. RESULTS Mean left ventricular (LV) ejection fraction did not differ in ACROUNTR and in controls; at variance, ACROUNTR patients had reduced mean LV diastolic function (E/A ratio: 0.96+/-0.3 vs controls: 1.6+/-0.3; p<0.002). Impairment of global LV diastolic function was confirmed by PW-TDI in ACROUNTR patients having a normal systolic function. Regional myocardial systolic strain (epsilon) and strain rate (SR) values, indices of regional systolic heart deformation, were lower in ACROUNTR [epsilonsys (S) -19.8+/-2.9 and epsilonsys (L): -17.7+/-2.2] than in controls [epsilonsys (S): -27.9+/-3.8; p<0.001 and epsilonsys (L): -25.3+/-2.6; p<0.001]. In addition, the early phase of diastolic function, evaluated using SR parameters, was impaired in acromegalic patients (p<0.005 vs controls). Strain and SR values were related to serum GH and IGF-I levels (p<0.02) and greatly improved after a 6-month course with SSa [epsilonsys (S) improved to -23.8+/-3.8 (p<0.05) and epsilonsys (L) improved to -24.7+/-2.4 (p<0.03)]. CONCLUSIONS Our study confirms that ACROUNTR patients have impaired diastolic function. More important, our study clearly shows that ACROUNTR patients have an impairment of regional myocardial systolic function, which is not secondary to diastolic changes. These intramyocardial functional abnormalities improved during medical treatment of acromegaly. It is conceivable that GH-IGF-I excess has detrimental effects either on the diastolic or the systolic phases of heart function.

Abstract
Matrix metalloproteinases (MMPs), also designated as matrixins, play a central role in many biological processes and are involved both in physiologic cellular processes and in pathologic situations such as tumor growth, invasion and metastasis. For more than 30 years MMPs have been considered as promising targets for cancer therapy and a number of different synthetic and natural MMP inhibitors have been identified as cytostatic and anti-angiogenic agents and have begun clinical testing in view of their specific implication in malignant tissues. Although preclinical studies were so compelling to encourage several clinical trials, the past years have seen a consistent number of disappointments and limited success. The critical examination of previous studies shed light on new information about the cellular source, substrates and mode of action of MMPs, focusing the attention of future research on the identification of specific MMP targets in tumors at different stage of tumor progression, both in order to improve efficacy and to reduce the side effect profile. In this review we discuss the current view on the feasibility of MMPs as target for therapeutic intervention in cancer, taking into account that the perspective may be of great value for molecular medicine for the twenty-first century, providing intriguing information about the MMPs as mediators in biology and pathology, and as targets for disease therapies.

Abstract
New technologies and the availability of new echo-contrast agents have resulted in advances of diagnostic and prognostic indications of left ventricular opacification (LVO) and myocardial perfusion. The clinical diagnostic value of ultrasound contrast media for LVO and its impact on the clinical decision-making process has been demonstrated in several studies. Recent research aims at developing new quantitative software to improve the delineation of the endocardial border, to assess 3D myocardial perfusion for more accurate regional/global LV function measurements, and to evaluate 4D intra-cardiac flow dynamics. Furthermore, a general consensus has been reached on the incremental value of myocardial contrast echocardiography (MCE) for obtaining additional information in both chronic and acute coronary artery disease (CAD) patients and on the possibility to make quantitative measurements of microvascular damage. Q-contrast is a new software system which provides quantitative measurements to generate parametric images of microcirculatory flow. In a research project including 120 patients, Q-contrast software has been tested to assess the role of contrast in AMI (Acute Myocardial Infarction Contrast Imaging (A.M.I.C.I. Study); good agreement between parametric MCE and SPECT has been found. Preliminary results further confirm that quantitative MCE may provide additional clinical value over qualitative information for the assessment of LV function and of the effects of coronary artery disease on the myocardial microcirculation (viability, ischemia or infarct).

Abstract
Tissue Doppler echocardiography is a variation of conventional Doppler flow imaging. This modality allows quantification of the Doppler shift within the range of myocardial tissue motion. The velocity at a variety of myocardial sites can be determined and distinguished very rapidly by using Doppler techniques. The velocity of moving tissue can be studied with pulsed wave tissue Doppler sampling, which displays the velocity of a selected myocardial region against time, with high temporal resolution. In addition, the velocities can be calculated with time-velocity maps and displayed as color-encoded velocity maps in either an M-mode or 2-dimensional format. This review will focus on the technical aspects and the different methods of tissue Doppler echocardiography for the analysis of regional systolic and diastolic left ventricular function. Whereas pulsed wave tissue Doppler echocardiography allows measurements of velocities of a selected myocardial region, color tissue Doppler gives the best overview of cardiac dynamics because the entire scanned color data are displayed simultaneously. However, there is an increasing need for objective evaluation of tissue Doppler information. Digital images and postprocessing of the data allow for quantitative off-line analysis, and the different approaches and parameters proposed from different centers are discussed.

Abstract
Noninvasive estimation of diastolic pressure gradients has recently been validated using the space-temporal velocity distribution available from colour Doppler M-mode (CDM). However, the methods currently applied for analysing CDM patterns of left ventricular (LV) filling have limitations, such as lack of automation, subjective variability and limited use of digital velocity map. For this reason, we have developed software able to acquire and process the CDM maps; thus, providing an easily interpretable graphical and numerical display. The pressure field is obtained by approximating the derivatives with centred finite differences via the incompressible Navier-Stokes equations. After digital filtering of the noise and the removal of the colour black spots, the velocity field is utilised to compute the pressure gradient field and the pressure values by spatial integration. It is concluded that automatic quantification of colour CDM patterns is feasible and will be a strategic tool in the investigation of one of the most intriguing topics in cardiology.

However, there is an increasing need for objective evaluation of tissue Doppler information. Digital images and data post-processing allow for quantitative off-line analysis, and the different approaches and parameters proposed from different centers are discussed. In recent years, tissue Doppler imaging has been applied for accurate evaluation of diastolic function, quantifying regional function particularly during stress, pre-excitation syndrome, and left ventricular hypertrophy. The results of these experiences indicate that tissue Doppler imaging is a promising technique for quantifying the response of the myocardium and endocardium during both normal and abnormal function. Again, there is a significant learning curve concerning its application, but with experience it will be a useful and reproducible technique.
