Inflammation, Oxidative Stress, and Endothelial Dysfunction in the Pathogenesis of Vascular Damage: Unraveling Novel Cardiovascular Risk Factors in Fabry Disease.

Anderson-Fabry disease (AFD), a genetic disorder caused by mutations in the α-galactosidase-A (GLA) gene, disrupts lysosomal function, leading to vascular complications. The accumulation of globotriaosylceramide (Gb3) in arterial walls triggers upregulation of adhesion molecules, decreases endothelial nitric oxide synthesis, and induces reactive oxygen species production. This cascade results in fibrotic thickening, endothelial dysfunction, hypercontractility, vasospasm, and a pro-thrombotic phenotype. AFD patients display increased intima-media thickness (IMT) and reduced flow-mediated dilation (FMD), indicating heightened cardiovascular risk. Nailfold capillaroscopy (NFC) shows promise in diagnosing and monitoring microcirculatory disorders in AFD, though it remains underexplored. Morphological evidence of AFD as a storage disorder can be demonstrated through electron microscopy and immunodetection of Gb3. Secondary pathophysiological disturbances at cellular, tissue, and organ levels contribute to the clinical manifestations, with prominent lysosomal inclusions observed in vascular, cardiac, renal, and neuronal cells. Chronic accumulation of Gb3 represents a state of ongoing toxicity, leading to increased cell turnover, particularly in vascular endothelial cells. AFD-related vascular pathology includes increased renin-angiotensin system activation, endothelial dysfunction, and smooth muscle cell proliferation, resulting in IMT increase. Furthermore, microvascular alterations, such as atypical capillaries observed through NFC, suggest early microvascular involvement. This review aims to unravel the complex interplay between inflammation, oxidative stress, and endothelial dysfunction in AFD, highlighting the potential connections between metabolic disturbances, oxidative stress, inflammation, and fibrosis in vascular and cardiac complications. By exploring novel cardiovascular risk factors and potential diagnostic tools, we can advance our understanding of these mechanisms, which extend beyond sphingolipid accumulation to include other significant contributors to disease pathogenesis. This comprehensive approach can pave the way for innovative therapeutic strategies and improved patient outcomes.

Myocardial deformational adaptations to different forms of training: a real-time three-dimensional speckle tracking echocardiographic study.

The hemodynamic load due to physical activity leads to structural and functional cardiac adaptations known as "Athlete's heart". We aimed to compare myocardial performance in different groups of trained athletes by means of 3D echocardiography and 3D speckle tracking echocardiography (3D-STE). 66 athletes [26 strength-trained athletes (STA) and 40 endurance athletes (ETA)] were prospectively enrolled. A control group of 40 sedentary subjects (sedentary group) was also included. All subjects underwent both standard and 3D evaluation of left ventricular (LV) function including 3D-STE. Left ventricular mass indexed for body surface area, LV end-diastolic (LV Dd) thickness of interventricular septum and posterior wall thickness mean values were significantly increased in athletes (p < 0.001, p < 0.01 and p < 0.001, respectively). LV diastolic diameter index had a significantly higher mean value in ETA in respect to sedentary group (p = 0.001). Despite a preserved mean value of LV ejection fraction (LV EF) in all the groups, subjects in STA group showed a significant reduction of strain in the longitudinal, radial and circumferential directions (p < 0.05 for all). Area strain mean value was also reduced in STA group (p < 0.01). In the overall population, an inverse relationship between longitudinal strain and LV Dd index (r = -0.260, p = 0.008), the E/A ratio (r = -0.249, p = 0.010) and the E' velocity (r = -0.259, p = 0.009) has been identified. Sport-specific patterns of ventricular morphological and functional remodeling are present in athletes performing different kinds of training. 3D-STE is a useful and feasible echocardiographic technique for the assessment of sport-specific pattern of deformational adaptations.

The added value of the HFA/ICOS score in the prediction of chemotherapy-related cardiac dysfunction in breast cancer.

BACKGROUND: The 2022 ESC Guidelines on Cardio-Oncology recommend baseline cardiovascular risk stratification before starting anticancer drugs, using the new risk assessment tools proposed by the Heart Failure Association (HFA) and the International Cardio-Oncology Society (ICOS).Our study aimed to assess the clinical application of HFA/ICOS risk score in breast cancer patients undergoing chemotherapy and its usefulness in predicting the development of chemotherapy-related cardiac dysfunction (CTRCD). METHODS: A prospective multicentric study enrolled 109 breast cancer patients treated with anthracyclines with or without trastuzumab. A cardiological evaluation, including ECG and echocardiogram at baseline (T0), 3 (T1), 6 (T2), and 12 months (T3) after starting treatment was performed. HFA/ICOS score was assessed in all patients. The population was divided into low, medium, high, and very-high risk.During follow-up, CTRCD and other cardiovascular events have been evaluated. RESULTS: 61 patients were low risk, 37 medium, 9 high, 2 very-high risk criteria. We found a significantly higher incidence of overall cardiotoxicity (CTRCD and other cardiovascular events) in the very-high risk group (100%) compared with the medium (29%) and low risk groups (13%). CTRCD incidence was also significantly higher in the high risk group (55%). CTRCD resulted as being associated with baseline arterial hypertension and baseline HFA/ICOS risk score of high ( p  = 0.006) or very-high ( p  < 0.0001). CONCLUSION: Our study confirms the HFA/ICOS score's ability to predict cardiovascular toxicity in breast cancer women and the need for close monitoring especially in high and very-high risk patients.

Relationship between Capillaroscopic Architectural Patterns and Different Variant Subgroups in Fabry Disease: Analysis of Cases from a Multidisciplinary Center.

Anderson-Fabry disease (AFD) is a genetic lysosomal storage disorder caused by mutations in the α-galactosidase A gene, leading to impaired lysosomal function and resulting in both macrovascular and microvascular alterations. AFD patients often exhibit increased intima-media thickness (IMT) and reduced flow-mediated dilation (FMD), indicating non-atherosclerotic arterial thickening and the potential for cardiovascular events. Nailfold capillaroscopy, a non-invasive diagnostic tool, has shown potential in diagnosing and monitoring microcirculatory disorders in AFD, despite limited research. This study evaluates nailfold capillaroscopy findings in AFD patients, exploring correlations with GLA gene variant subgroups (associated with classical or late-onset phenotypes and variants of uncertain significance (VUSs)), and assessing morpho-functional differences between sexes. It aims to determine whether capillaroscopy can assist in the early identification of individuals with multiorgan vascular involvement. A retrospective observational study was conducted with 25 AFD patients from AOUP "G. Rodolico-San Marco" in Catania (2020-2023). Patients underwent genetic testing, enzyme activity evaluation, and nailfold capillaroscopy using Horus basic HS 200 videodermatoscopy. Parameters like angiotectonic disorder, vascular areas, capillary density, and intimal thickening were assessed. The study identified significant differences in capillaroscopy findings among patients with different GLA gene variant subgroups. Classic AFD variant patients showed reduced capillary length and signs of erythrocyte aggregation and dilated subpapillary plexus. No correlation was found between enzymatic activity and capillaroscopy parameters. However, Lyso-Gb3 levels were positively correlated with average capillary length (ῤ = 0.453; p = 0.059). Sex-specific differences in capillaroscopy findings were observed in neoangiogenesis and average capillary length, with distinct implications for men and women. This study highlights the potential of nailfold capillaroscopy in the diagnostic process and clinical management of AFD, particularly in relation to specific GLA gene mutations, as a valuable tool for the early diagnosis and monitoring of AFD.

Systemic Vascular Resistance and Myocardial Work Analysis in Hypertrophic Cardiomyopathy and Transthyretin Cardiac Amyloidosis with Preserved Left Ventricular Ejection Fraction.

Background: The pathophysiological impact of systemic vascular resistance (SVR) and pressure-strain loop-derived global myocardial work index (GWI) in hypertrophic cardiomyopathy (HCM) and transthyretin cardiac amyloidosis (ATTR) has been randomly investigated. Methods: Both SVR and GWI were assessed in outpatients consecutively referred at two Italian cardiology departments for heart failure with preserved left ventricular ejection fraction (LVEF), affected by either nonobstructive HCM or wild-type ATTR. Based on relevant cross-tabulations, the patients were gathered into 4 functional classes according to cut-off values of 1440 dyne/s/cm-5 for SVR, and 1576 mm Hg% for GWI, as suggested by previous studies. Results: A total of 60 patients, 30 in each group, aged 61 ± 16 years, with 78% males, were studied. HCM patients were younger than those with ATTR and in a better clinical condition (23% HCM vs. 77% ATTR were NYHA class II-III, p < 0.001). Overall, 51 patients (85%) showed a high SVR, 21/30 HCM (70%), and 30 ATTR (100%) (p < 0.005). Both SVR and GWI (expressions of ventricular-arterial coupling) were impaired in 43% of HCM patients (showing greater LV concentric hypertrophy) and 93% of ATTR patients (in advanced NYHA functional class) (p < 0.001). Conclusions: A substantial percentage of present study population showed impaired SVR and/or GWI, despite preserved LVEF. The proposed classification may shed further light on the pathophysiological and clinical characteristics of such hypertrophic phenotypes.

Management of cancer patients at high and very-high risk of cardiotoxicity: Main questions and answers.

In recent years, important advances have been made in the field of Cardio-Oncology. The 2022 ESC Guidelines on Cardio-Oncology proposed a baseline cardiovascular risk stratification for cancer patients and preventive strategies in patients at high and very-high risk of cardiotoxicity. Cardiovascular toxic effects of anti-cancer drugs are being extensively studied; surveillance programs have been proposed, based on the baseline cardiovascular risk. On the other hand, there is little data on Cardio-Oncological management of patients at high and very-high cardiovascular risk with previous cardiovascular diseases. For example, little is known about management of cancer patients with heart failure with reduced ejection fraction (HFrEF), patients with a recent myocardial infarction or other cardiovascular diseases; when to resume anti-cancer drugs after a cardiovascular toxic event. Collaboration between Cardiologists and Oncologists and multidisciplinary team evaluations are certainly essential to decide the best therapeutic strategy for cancer patients, to treat cancer while saving the heart. Therefore, in the present review, we attempt to provide a useful guide to clinicians in treating patients with high and very-high risk of cardiotoxicity by enucleating main questions and answering them based on the evidence available as well as expert opinion and our clinical experience.

Aortopathy and aortic valve surgery in patients with bicuspid aortic valve with and without raphe.

AIM: To evaluate the association between raphe in bicuspid aortic valve (BAV) patients and valve dysfunction, aortopathy and aortic valve surgery in the REBECCA registry [REgistro della valvola aortica Bicuspide della Società Italiana di ECocardiografia e CArdiovascular Imaging (SIECVI)]. METHODS: Prevalence of aortic valve dysfunction and aortopathy was investigated in BAV patients with and without raphe. Aortic valve dysfunction (regurgitation or stenosis) was categorized as mild, moderate and severe. Aortopathy was defined as annulus ≥14 mm/m2; root ≥20 mm/m2; sinotubular junction ≥16 mm/m2; ascending aorta ≥17 mm/m2, and classified in Type A, isolated ascending aorta dilatation; Type B, aortic root and ascending aorta dilatation; and Type C, isolated aortic root dilatation. RESULTS: Overall, 695 patients with BAV were enrolled; 520 (74.8%) with raphe and 175 (25.2%) without raphe. BAV patients with raphe presented more frequently with moderate or severe aortic stenosis than BAV patients without raphe (183 [35.2%] vs 34 [19.4%], p < 0.001). A higher prevalence of aortopathy, particularly Type B, was observed in patients with vs without raphe. At multivariable analysis, raphe was a predictor of aortic valve surgery at three-year follow-up (odds ratio 2.19, 95% confidence interval 1.08-4.44, p < 0.001). CONCLUSIONS: Patients with BAV and raphe have a higher prevalence of significant aortic stenosis, aortopathy, especially Type B, and a higher risk of undergoing aortic valve surgery at three-year follow-up.

Speckle tracking echocardiography-derived parameters as new prognostic markers in hypertrophic cardiomyopathies.

Aims: Hypertrophic cardiomyopathies (HCM) are caused in 30-60% of cases by mutations in cardiac sarcomere genes but can also be an expression of cardiac involvement in multi-systemic metabolic diseases, such as Anderson-Fabry disease (AFD). HCM entails a risk of sudden cardiac death (SCD) of 0.9%/year and is the most common cause of SCD in young adults. Recent studies suggested mechanical dispersion (MD) by speckle tracking echocardiography (STE) as an additional arrhythmic risk marker. The aim of the study was to evaluate left ventricle global longitudinal strain (LV-GLS) and MD, in patients with HCM or AFD cardiomyopathy, and the association with ventricular arrhythmias (V-AR). Methods and results: We evaluated 40 patients with HCM, 57 with AFD (12 with LV hypertrophy and 45 without), and 40 healthy subjects, between January 2014 and June 2022. We performed a comprehensive echocardiographic study and analysed systolic and diastolic functions, LV-GLS, and MD. We also analysed V-AR, including ventricular fibrillation and sustained/non-sustained ventricular tachycardia, by Holter electrocardiogram (Holter-EKG), in a subset of hypertrophic patients. Data were analysed by unpaired Student t-test or chi-square/Fisher's exact test as appropriate and binary logistic regression (SPSS Statistics ver.26). LV-GLS was significantly lower in the V-AR group compared with patients without V-AR (median -10.2% vs. -14%, P = 0.038); MD was significantly higher in the V-AR group (85.5 ms vs. 61.1 ms, P = 0.004). V-AR were found significantly associated with MD (OR, 1.030; 95% CI, 1.003-1.058; P = 0.03). Conclusions: MD is a useful additional index in the evaluation of patients with HCM and may be a promising prognostic predictor of increased arrhythmic risk.

Sex Differences in Anderson-Fabry Cardiomyopathy: Clinical, Genetic, and Imaging Analysis in Women.

Anderson-Fabry Disease (AFD) is a rare, systemic lysosomal storage disease triggered by mutations in the GLA gene, leading to α-galactosidase A (α-Gal A) deficiency. The disease's X-linked inheritance leads to more severe, early-onset presentations in males, while females exhibit variable, often insidious, manifestations, notably impacting cardiac health. This study aims to examine gender-based AFD cardiac manifestations in correlation with the variant type: classical (CL), late-onset (LO), or variants of uncertain significance (VUS). We analyzed data from 72 AFD patients (53 females, 19 males) referred to the "G. Rodolico" University Hospital, employing enzyme activity measurements, genetic analysis, periodic lyso-Gb3 monitoring, comprehensive medical histories, and advanced cardiac imaging techniques. Statistical analysis was performed using SPSS version 26. Our AFD cohort, with an average age of 45 ± 16.1 years, comprised 12 individuals with hypertrophy (AFD-LVH) and 60 without (AFD-N). Women, representing about 75% of the subjects, were generally older than men (47.2 ± 16.2 vs. 38.8 ± 14.6, p = 0.046). In the female group, 17% had CL variants, 43.3% LO, and 39.6% had VUS, compared to 21.1%, 36.8%, and 31.6% in the male group, respectively. Females exhibited significantly higher α-Gal A values (median 7.9 vs. 1.8 nmol/mL/h, p < 0.001) and lower lyso-Gb3 levels (1.5 [IQR 1.1-1.7] vs. 1.9 [1.5-17.3] nmol/L, p = 0.02). Regarding the NYHA class distribution, 70% of women were in class I and 28% in class II, compared to 84% and 16% of men, respectively. Among women, 7.5% exhibited ventricular arrhythmias (10.5% in men), and 9.4% had atrial fibrillation (10.5% in men). Cardiac MRIs revealed fibrosis in 57% of examined women, compared to 87% of men. Even among patients without LVH, significant differences persisted in α-Gal A and lyso-Gb3 levels (p = 0.003 and 0.04), as well as LVMi (61.5 vs. 77.5 g/sqm, p = 0.008) and GLS values (-20% vs. -17%, p = 0.01). The analysis underscored older age, decreased lyso-Gb3 deposition, reduced hypertrophy, and lesser GLS compromise in females, suggesting later disease onset. Severe cardiac patterns were associated with classic variants, while more nuanced manifestations were noted in those with VUS. Early GLS impairment in males, irrespective of hypertrophy, emphasized the role of subclinical damage in AFD.

Interdisciplinary Multidimensional Assessment of Transthyretin Amyloidosis before and after Tafamidis.

BACKGROUND: Clinically, there is considerable heterogeneity in the presentation of transthyretin amyloidosis (ATTR), which ranges from primarily cardiac and primarily neurologic to mixed disease, among other manifestations. Because of this complex presentation, the diagnosis and management of patients with ATTR are often challenging and should be performed in interdisciplinary centers specialized in amyloidosis. Here, we aimed to increase awareness of ATTR detection and pathophysiology through a multidimensional multiorgan approach. CASE REPORT: We reported on a 60-year-old man with wild-type ATTR who underwent a number of both basic and advanced cardiological and neurological investigations at baseline and after a treatment period with the TTR tetramer stabilizer, tafamidis. Several findings are provided here, some of which might be considered instrumental correlates of the patient's clinical improvement after therapy. CONCLUSIONS: Adequate awareness and prompt recognition of ATTR support early diagnosis and faster access to therapies, thereby slowing the progression and improving the prognosis. The need for a multidisciplinary alliance between specialists and the opportunity to perform, at least in selected cases, a set of specific examinations for a detailed assessment of ATTR patients can also provide valuable insights into the physiopathology and response to therapy of a disease as complex and intriguing as ATTR.

Myocardial Work Appraisal in Transthyretin Cardiac Amyloidosis and Nonobstructive Hypertrophic Cardiomyopathy.

Global left ventricular (LV) myocardial work (MW) indexes can be recognized at ultrasound imaging from the LV pressure/global longitudinal strain (GLS) loop analysis. A total of 4 indexes, global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE), have been demonstrated to overcome the methodological limitations of GLS and provide useful information on myocardial dysfunction in some clinical settings. Although impaired MW indexes have been demonstrated in patients with transthyretin cardiac amyloidosis (ATTR) or with nonobstructive hypertrophic cardiomyopathy (HCM), there are no comparative studies at present. This study aimed to describe the characteristics of MW in both these clinical settings compared with patients with well-controlled hypertension (HTN). A total of 83 patients, 32 with ATTR (aged 70 ± 11 years, 32% mutated, 68% wild-type, 72% men), 29 with HCM (aged 57 ± 17 years), and 22 HTN controls (aged 56 ± 5.6 years, 59% men) were prospectively enrolled at 2 clinical centers. All participants had New York Heart Association class I or II. Overall, the LV mass index was greater in both study groups than in HTN, whereas the LV ejection fraction (EF) was significantly lower in ATTR compared with other groups. Based on this finding, patients with ATTR were further divided into 2 subgroups: ATTR1 (LVEF ≤0.50), n = 14 (44%) and ATTR2 (LVEF >0.50), n = 18 (56%). Overall, the GWI and GCW were lower in all ATTR patients (mostly in ATTR1) than in the other groups (p <0.001), whereas only small differences in GWE and none in GWW were found among the groups. Of interest, the pairwise comparison and receiver operating characteristic analysis in preserved LVEF patients showed that GWI was a better discriminator of ATTR2 from HCM patients than GLS, with the cut-off value ≤1,419 mm Hg% (89% sensitivity; 55% specificity; p = 0.013). In conclusion, MW analysis was confirmed to be a modern way to investigate myocardial function in patients with hypertrophic phenocopies. GWI and GCW were more impaired in patients with ATTR compared with HCM and HTN controls. Furthermore, this study likely revealed an additional discriminative value of GWI over GLS alone in preserved LVEF settings.

Heart Rate Variability Indices of Student Pilots Undergo Modifications During Flight Training.

INTRODUCTION: Heart rate variability (HRV) indicates the temporal fluctuation of the intervals between adjacent beats. HRV expresses neuro-cardiac activity and is generated by heart-brain interactions and dynamics related to the function of the autonomous nervous system and other components. To investigate this issue, we started a series of experiments by coupling the flight tasks of student pilots and their HRV.METHODS: Before each experimental session, the participating student was fitted with a five-electrode, three-channel Holter electrocardiogram monitor. We defined three time-phases for each training mission: before flight operations on the ground, during flight operations, and after flight operations on the ground. The HRV analysis was performed by quantifying some indices of the time domain and the frequency domain.RESULTS: The analysis of RR-wave intervals revealed two types of trends: 1) students whose RR intervals decreased during flight operations compared to before flight ground operations; and 2) students whose RR intervals increased during flight operations compared to before flight ground operations. These differences found in the RR intervals produced changes in the indices of both the time and frequency domains of the two students' samples.DISCUSSION: Flight training involves regular and advanced tasks and/or emergency situations. When this happens, the total power of the heart decreases because the RR intervals are forced toward low values. Flight activity involves continuous demanding tasks that can be potentially read by an analysis of the HRV; a high HRV ensures better management of tasks that require a greater commitment of cardiovascular function.Li Volsi G, Monte IP, Aruta A, Gulizzi A, Libra A, Mirulla S, Panebianco G, Patti G, Quattrocchi F, Bellantone V, Castorina W, Arcifa S, Papale F. Heart rate variability indices of student pilots undergo modifications during flight training. Aerosp Med Hum Perform. 2023; 94(11):835-842.

Heart Rate Variability of a Student Pilot During Flight Training.

BACKGROUND: Heart rate (HR) indicates the number of beats per minute (bpm) of the heart, while heart rate variability (HRV) indicates the temporal fluctuation of the intervals between adjacent beats (NN). HRV expresses neuro-cardiac activity and is generated by heart-brain interactions and dynamics related to the function of the autonomic nervous system (ANS) and other components (e.g., body and ambient temperature, respiration, hormones, blood pressure). We are carrying out a series of experimental investigations with the aim of studying HRV in student pilots during training.CASE REPORT: For this purpose, we used a Holter electrocardiograph equipped with three channels and five electrodes positioned on the chest of the subject who participated in our investigation. The case report refers to a student pilot who, during a flight mission with the instructor, had to face a forced landing and a flap failure. We report data based on analysis of the time domain and frequency domain related to operations on the ground before the flight, during the flight, and on the ground after the flight.DISCUSSION: Our initial conclusion is that the extent of HRV constitutes an "energy store" for better cardiac performance in eustress activities. During advanced tasks, the "Total Power" of the heart decreases because the RR intervals are forced toward low values, where the heart is less able to be modulated by its many controllers. Furthermore, this experimental protocol can be useful to flight instructors for the training process of student pilots.Li Volsi G, Monte IP, Aruta A, Gulizzi A, Libra A, Mirulla S, Panebianco G, Patti G, Quattrocchi F, Bellantone V, Castorina W, Arcifa S, Papale F. Heart rate variability of a student pilot during flight training. Aerosp Med Hum Perform. 2023; 94(6):475-479.

Left Atrial Strain Imaging by Speckle Tracking Echocardiography: The Supportive Diagnostic Value in Cardiac Amyloidosis and Hypertrophic Cardiomyopathy.

Background: Left atrial (LA) function is crucial for assessing left ventricular filling in various cardiovascular conditions. Cardiac Amyloidosis (CA) is characterized by atrial myopathy and LA function impairment, with diastolic dysfunction up to restrictive filling pattern, leading to progressive heart failure and arrhythmias. This study evaluates LA function and deformation using speckle tracking echocardiography (STE) in patients with CA compared to a cohort of patients with sarcomeric Hypertrophic Cardiomyopathy (HCM) and a control group. Methods: We conducted a retrospective, observational study (from January 2019 to December 2022) including a total of 100 patients: 33 with ATTR-CA, 34 with HCMs, and 33 controls. Clinical evaluation, electrocardiograms, and transthoracic echocardiography were performed. Echocardiogram images were analyzed in post-processing using EchoPac software for LA strain quantification, including LA-reservoir, LA-conduit, and LA-contraction strain. Results: The CA group exhibited significantly impaired LA function compared to HCMs and control groups, with LA-reservoir median values of -9%, LA-conduit -6.7%, and LA-contraction -3%; this impairment was consistent even in the CA subgroup with preserved ejection fraction. LA strain parameters correlated with LV mass index, LA volume index, E/e', and LV-global longitudinal strain and were found to be associated with atrial fibrillation and exertional dyspnea. Conclusions: LA function assessed by STE is significantly impaired in CA patients compared to HCMs patients and healthy controls. These findings highlight the potential supportive role of STE in the early detection and management of the disease.

Strain and Myocardial Work Index during Echo Exercise to Evaluate Myocardial Function in Athletes.

The aim of the study was to evaluate the application of global longitudinal strain (GLS) and myocardial work (MW) at rest and during exercise in healthy sedentary or trained participants, to test their ability to improve echocardiographic information and to complement prescribing exercise, cardiac screening, or rehabilitation programs. Methods: Thirty healthy males were divided into three groups of 10, sedentary (G1), resistance (G2) and power (G3) athletes, underwent a standard clinical evaluation protocol and exercise stress testing echocardiography. Results: During stress, all showed increased left ventricular ejection fraction and mitral annulus tissue Doppler (E'). G1 showed a decrease in left atrial volume (LAVi) as opposed to an increase in G3. E/E 'a decrease in G2, unlike the increase in G3. All groups showed increase of Strain (GLS average AV, Longitudinal LS, Medio-Basal MB Apical AP), global constructive work (GCW), and Global wasted work. G1 showed increase for global work efficiency, G2 and G3 for global work index (GWI). G3 showed a greater variation of E/E', LAVi, GWI and GCW compared to G1 and G2, greater of GLS AV, LS-AP compared to G2. Only G3 showed differences for GLS AV versus LS-AP. The relative regional strain ratio showed a greater value in G3 versus G1 at the end of stress compared to rest. Conclusions: The new echocardiographic applications to study the physiological adaptation could open new perspectives for the diagnostic and therapeutic development through the prescription of personalized exercises and screening and follow-up of the early pathological changes of the athlete's heart.

Fabry's Disease: The Utility of a Multidisciplinary Screening Approach.

(1) Background: As a lysosomal storage disorder, Fabry's disease (FD) shows variable clinical manifestations. We applied our multidisciplinary approach to identify any organ damage in a sample of adult patients with different pathogenic variants. (2) Methods: 49 participants (mean age 44.3 ± 14.2 years; 37 females), underwent a multidimensional clinical and instrumental assessment. (3) Results: At diagnosis, mean enzymatic activity was 5.2 ± 4.6 nM/mL/h in females and 1.4 ± 0.5 nM/mL/h in males (normal values > 3.0), whereas globotriaosylsphingosine was 2.3 ± 2.1 nM/L in females and 28.7 ± 3.5 nM/L in males (normal values < 2.0). Overall, cardiovascular, neurological, and audiological systems were the most involved, regardless of the variant detected. Patients with classic variants (10) showed typical multiorgan involvement and, in some cases, prevalent organ damage (cardiovascular, neurological, renal, and ocular). Those with late-onset variants (39) exhibited lower occurrence of multiorgan impairment, although some of them affected the cardiovascular and neurological systems more. In patients with lower enzymatic activity, the most frequent involvement was neurological, followed by peripheral vascular disease. (4) Conclusions: FD patients exhibited wide phenotypic variability, even at single-organ level, likely due to the individual genetic mutation, although other factors may contribute. Compared to the conventional management, a multidisciplinary approach, as that prompted at our Center, allows one to achieve early clinical detection and management.

Imaging Quality Control, Methodology Harmonization and Clinical Data Management in Stress Echo 2030.

Stress echo (SE) 2030 study is an international, prospective, multicenter cohort study that will include >10,000 patients from ≥20 centers from ≥10 countries. It represents the logical and chronological continuation of the SE 2020 study, which developed, validated, and disseminated the "ABCDE protocol" of SE, more suitable than conventional SE to describe the complex vulnerabilities of the contemporary patient within and beyond coronary artery disease. SE2030 was started with a recruitment plan from 2021 to 2025 (and follow-up to 2030) with 12 subprojects (ranging from coronary artery disease to valvular and post-COVID-19 patients). With these features, the study poses particular challenges on quality control assurance, methodological harmonization, and data management. One of the significant upgrades of SE2030 compared to SE2020 was developing and implementing a Research Electronic Data Capture (REDCap)-based infrastructure for interactive and entirely web-based data management to integrate and optimize reproducible clinical research data. The purposes of our paper were: first, to describe the methodology used for quality control of imaging data, and second, to present the informatic infrastructure developed on RedCap platform for data entry, storage, and management in a large-scale multicenter study.

Valvular Damage.

Valvular heart diseases (VHD) may be observed in patients with cancer for several reasons, including preexisting valve lesions, radiotherapy, infective endocarditis, and secondary to the left ventricle dysfunction. The incidence of VHD is especially in younger survivors treated with thoracic radiation therapy for certain malignancies, such as Hodgkin's lymphoma and breast cancer. The mechanism of radiation-induced damage to heart valves is not clear and includes diffuse fibrocalcific thickening of the valve. VHD is commonly diagnosed after a long latent period, in the context of clinical symptoms, or suspected on the basis of a new murmur. The evaluation includes identification of anatomical valve abnormalities, valve dysfunction, and assessing the functional consequences of valve dysfunction on the ventricles. Echocardiography is the optimal imaging technique for diagnostic and therapeutic management. Cardiovascular magnetic resonance and computed tomography (CT) may be used to assess the severity of VHD, but cardiac CT is mainly useful for detecting extensive calcifications of the ascending aorta. Patients exposed to mediastinal radiotherapy and minimal valve dysfunction require follow-up of 2-3 years, with moderate valve disease yearly, with severe, should be assessed for valve surgery.

Thrombotic Risk in Cancer Patients: Diagnosis and Management of Venous Thromboembolism.

Venous thromboembolism (VTE) represents a major health problem, especially in cancer patients, who experience a significantly higher incidence of both deep vein thrombosis and pulmonary embolism compared to the general population. Indeed, patients with cancer have a prothrombotic state resulting in both increased expression of procoagulants and suppression of fibrinolytic activity. In addition, VTE increases the morbidity and mortality of these patients. For all these reasons, the prevention and treatment of VTE in cancer setting represent major challenges in daily practice. In general, low-molecular-weight heparin monotherapy is the standard of care for the management of cancer-associated VTE, as Vitamin K antagonists are less effective in this setting. Direct oral anticoagulants offer a potentially promising treatment option for cancer patients with VTE, since recent studies demonstrated their efficacy and safety also in this peculiar setting.

Cardiac Tumors.

Cardiac tumors (CTs) are extremely rare, with an incidence of approximately 0.02% in autopsy series. Primary tumors of the heart are far less common than metastatic tumors. CTs usually present with any possible clinical combination of heart failure, arrhythmias, or embolism. Echocardiography remains the first diagnostic approach when suspecting a CT which, on the other side, frequently appears unexpectedly during an echocardiographic examination. Yet, cardiac tomography and especially magnetic resonance imaging may offer several adjunctive opportunities in the diagnosis of CTs. Early and exact diagnosis is crucial for the following therapy and outcome of CTs.
