Abstract
BACKGROUND Whether, and to what extent, frailty and other geriatric domains are linked to health status in patients with transthyretin cardiac amyloidosis (ATTR-CA) is unknown. AIMS To determine the association of frailty with health status [defined by the Kansas City Cardiomyopathy Questionnaire (KCCQ)] in patients with ATTR-CA. METHODS Consecutive ATTR-CA patients undergoing cardiovascular assessment at a tertiary care clinic from September 2021 to September 2023 were invited to participate. KCCQ, frailty and social environment were recorded. Frailty was assessed using the modified Frailty Index (mFI), mapping 11 variables from the Canadian Study of Health and Aging (frailty ≥0.36). RESULTS Of 168 screened ATTR-CA patients, 138 [83% men, median age of 79 (75-84) years] were enrolled in the study. Median KCCQ was 66 (50-75). wtATTR-CA was the most prevalent form (N = 113, 81.9%). The most frequent cardiac variant was Ile68Leu (17/25 individuals with vATTR-CA). Twenty (14.5%) patients were considered frail, and prevalence of overt disability was 6.5%. At multivariable linear regression analysis, factors associated with worsening KCCQ were age at evaluation, the mFI, NYHA Class, and NAC Score. Gender, ATTR-CA type, phenotype, and LVEF were not associated with health status. DISCUSSION In older patients diagnosed with ATTR-CA, frailty, symptoms, and disease severity were associated with KCCQ. CONCLUSIONS Functional status is a determinant of quality of life and health status in older individuals with a main diagnosis of ATTR-CA. Future research may provide more in-depth knowledge on the association of frailty in patients with ATTR-CA with respect to quality of life and prognosis.

Abstract
BACKGROUND The extent of myocardial bone tracer uptake with technetium pyrophosphate, hydroxymethylene diphosphonate, and 3,3-diphosphono-1,2-propanodicarboxylate in transthyretin amyloid cardiomyopathy (ATTR-CM) might reflect cardiac amyloid burden and be associated with outcome. METHODS Consecutive patients with ATTR-CM who underwent diagnostic bone tracer scintigraphy with acquisition of whole-body planar and cardiac single-photon emission computed tomography (SPECT) images from the National Amyloidosis Centre and 4 Italian centers were included. Cardiac uptake was defined according to the Perugini classification: 0=absent cardiac uptake; 1=mild uptake less than bone; 2=moderate uptake equal to bone; and 3=high uptake greater than bone. Extent of right ventricular (RV) uptake was defined as focal (basal segment of the RV free wall only) or diffuse (extending beyond basal segment) on the basis of SPECT imaging. The primary outcome was all-cause mortality. RESULTS Among 1422 patients with ATTR-CM, RV uptake accompanying left ventricular uptake was identified by SPECT imaging in 100% of cases at diagnosis. Median follow-up in the whole cohort was 34 months (interquartile range, 21 to 50 months), and 494 patients died. By Kaplan-Meier analysis, diffuse RV uptake on SPECT imaging (n=936) was associated with higher all-cause mortality compared with focal (n=486) RV uptake (77.9% versus 22.1%; P<0.001), whereas Perugini grade was not associated with survival (P=0.27 in grade 2 versus grade 3). On multivariable analysis, after adjustment for age at diagnosis (hazard ratio [HR], 1.03 [95% CI, 1.02-1.04]; P<0.001), presence of the p.(V142I) TTR variant (HR, 1.42 [95% CI, 1.20-1.81]; P=0.004), National Amyloidosis Centre stage (each category, P<0.001), stroke volume index (HR, 0.99 [95% CI, 0.97-0.99]; P=0.043), E/e' (HR, 1.02 [95% CI, 1.007-1.03]; P=0.004), right atrial area index (HR, 1.05 [95% CI, 1.02-1.08]; P=0.001), and left ventricular global longitudinal strain (HR, 1.06 [95% CI, 1.03-1.09]; P<0.001), diffuse RV uptake on SPECT imaging (HR, 1.60 [95% CI, 1.26-2.04]; P<0.001) remained an independent predictor of all-cause mortality. The prognostic value of diffuse RV uptake was maintained across each National Amyloidosis Centre stage and in both wild-type and hereditary ATTR-CM (P<0.001 and P=0.02, respectively). CONCLUSIONS Diffuse RV uptake of bone tracer on SPECT imaging is associated with poor outcomes in patients with ATTR-CM and is an independent prognostic marker at diagnosis.

Abstract
BACKGROUND A minority of patients with hypertrophic cardiomyopathy (HCM) presents advanced heart failure (HF) during their clinical course, in the context of left ventricular (LV) remodeling with reduced LV ejection fraction (LVEF), or of severe diastolic dysfunction without impaired LVEF. Aim of this study was to describe a multicentric end stage (ES) HCM population and analyze clinical course and outcome among its different phenotypes. METHODS Data of all HCM patients from 7 Italian referral centres were retrospectively evaluated. ES was diagnosed in presence of: LVEF <50% (ES-rEF) or NYHA functional class ≥II with severe diastolic dysfunction (ES-pEF). Outcomes were: HCM-related and all-cause mortality; combined arrhythmic events; advanced HF treatments. RESULTS Study population included 331 ES patients; 87% presented ES-rEF and 13% ES-pEF. At ES recognition, patients with ES-pEF were more commonly females, had more frequently NYHA III/IV, atrial fibrillation and greater maximal LV wall thickness. Over a median follow-up of 5.6 years, 83 (25%) patients died, 46 (15%) experienced arrhythmic events and (26%) 85 received advanced HF treatments. Incidence of HCM-related and all-cause mortality, and of combined arrhythmic events did not differ in ES-pEF and ES-rEF patients, but ES-pEF patients were less likely to receive advanced HF treatments. Older age at ES recognition was an independent predictor of increased HCM-related mortality (p = 0.01) and reduced access to advanced HF treatments (p < 0.0001). CONCLUSIONS Two different HCM-ES phenotypes can be recognized, with ES-pEF showing distinctive features at ES recognition and receiving less frequently advanced HF treatments. Older age at ES recognition has a major impact on outcomes.

Abstract
BACKGROUND Transthyretin cardiac amyloidosis (ATTR-CA) is a progressive cardiomyopathy. The clinical course varies among individuals and there are no established measures to assess disease progression. OBJECTIVES The goal of this study was to assess the prognostic importance of an increase in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and outpatient diuretic intensification (ODI) as markers of disease progression in a large cohort of patients with ATTR-CA. METHODS We evaluated landmark survival analysis based on worsening of NT-proBNP and requirement for ODI between time of diagnosis and a 1-year visit, and subsequent mortality in 2,275 patients with ATTR-CA from 7 specialist centers. The variables were developed in the National Amyloidosis Centre (NAC) cohort (n = 1,598) and validated in the external cohort from the remaining centers (n = 677). RESULTS Between baseline and 1-year visits, 551 (34.5%) NAC patients and 204 (30.1%) patients in the external validation cohort experienced NT-proBNP progression (NT-proBNP increase >700 ng/L and >30%), which was associated with mortality (NAC cohort: HR: 1.82; 95% CI: 1.57-2.10; P < 0.001; validation cohort: HR: 1.75; 95% CI: 1.32-2.33; P < 0.001). At 1 year, 451 (28.2%) NAC patients and 301 (44.5%) patients in the external validation cohort experienced ODI, which was associated with mortality (NAC cohort: HR: 1.88; 95% CI: 1.62-2.18; P < 0.001; validation cohort: HR: 2.05; 95% CI: 1.53-2.74; P < 0.001). When compared with patients with a stable NT-proBNP and stable diuretic dose, a higher risk of mortality was observed in those experiencing either NT-proBNP progression or ODI (NAC cohort: HR: 1.93; 95% CI: 1.65-2.27; P < 0.001; validation cohort: HR: 1.94; 95% CI: 1.36-2.77; P < 0.001), and those experiencing both NT-proBNP progression and ODI (NAC cohort: HR: 2.98; 95% CI: 2.42-3.67; P < 0.001; validation cohort: HR: 3.23; 95% CI: 2.17-4.79; P < 0.001). CONCLUSIONS NT-proBNP progression and ODI are frequent and consistently associated with an increased risk of mortality. Combining both variables produces a simple, universally applicable model that detects disease progression in ATTR-CA.

Abstract
BACKGROUND Transthyretin amyloid cardiomyopathy (ATTR-CM) is associated with a progressive reduction of functional capacity. The progression of cardiopulmonary exercise testing (CPET) parameters over time is still unknown. METHODS In this study, 55 patients with ATTR-CM underwent 2 serial cardiologic evaluations and CPETs in a national referral center for cardiac amyloidosis (Careggi University Hospital, Florence). RESULTS Forty-three patients (78%) had wild-type ATTR. Median age was 80 years (interquartile range [IQR] 76-83 years), and 50 of the patients (91%) were men. At baseline, median peak oxygen consumption (pVO2) was 15 mL/kg/min (IQR 12-18 mL/kg/min), percentage of predicted pVO2 (%ppVO2) was 71% (IQR 60%-83%) and VE/VCO2 slope was 31 (IQR 26-34). After a median follow-up of 14 months (IQR 13-16 months), pVO2, %ppVO2 and VE/VCO2 slope were significantly worsened (-1.29 mL/kg/min [95% confidence interval (CI): -1.85 to -0.74; P < 0.01], -4.5% [95% CI: -6.9 to -2.02; P < 0.01], and 8.6 [95% CI 6-11; P < 0.01], respectively). Furthermore, exercise time (-39 s, 95% CI: -59 to -19; P < 0.01), exercise tolerance (-0.47 metabolic equivalents, 95% CI: -0.69 to -0.2; P < 0.01), and peak systolic pressure (-10.8 mm Hg, 95% CI: -16.2 to -5.4; P < 0.01) were significantly reduced. The worsening in CPET variables did not correspond with a significant change in echocardiographic parameters. CONCLUSIONS Cardiorespiratory response to exercise significantly worsened over a short period of time in patients with ATTR-CM. Serial CPET may be useful to identify early disease progression.

Abstract
OBJECTIVE To describe the potential clinical cardiotoxicity of oncological treatments in a cohort of consecutive patients with hypertrophic cardiomyopathy (HCM), systematically followed-up at two national referral centers for HCM. Cardiotoxicity relates to the direct effects of cancer-related treatment on heart function, commonly presenting as left ventricular contractile dysfunction. However, limited data are available regarding cardiotoxic effects on HCM as most studies have not specifically analyzed the effects of oncological treatment in HCM populations. This gap in knowledge may lead to unjustified restriction of HCM patients from receiving curative cancer treatments. METHODS We retrospectively analyzed clinical and instrumental data of all consecutive HCM patients who underwent oncological treatment between January 2000 and December 2020 collected in a centralized database. RESULTS Of 3256 HCM patients, 121 (3.7%) had cancer; 110 (90.9%) underwent oncological surgery, 45 (37.2%) received chemotherapy, and 22 (18.2%) received chest radiation therapy (cRT). After a median follow-up of 5.2 years (Q1-Q3: 2-13 years) from oncological diagnosis, 32 patients died. The cumulative survival at 5 years was 79.9%. The cause of death was mainly attributed to the oncological condition, whereas four patients died of sudden cardiac death without receiving previous chemotherapy or cRT. No patient interrupted or reduced the dose of oncological treatment due to cardiac dysfunction. No sustained ventricular tachyarrhythmia was induced by chemotherapy or radiation therapy. CONCLUSION Cancer treatment was well tolerated in HCM patients. In our consecutive series, none died of cardiovascular complications induced by chemotherapy or cRT and they did not require interruption or substantial treatment tapering due to cardiovascular toxic effects. Although a multidisciplinary evaluation is necessary and regimens must be tailored individually, the diagnosis of HCM per se should not be considered a contraindication to receive optimal curative cancer treatment.

Abstract
AIMS Whether pregnancy is a modifier of the long-term course and outcome of women with hypertrophic cardiomyopathy (HCM) is unknown. We assessed the association of pregnancy with long-term outcomes in HCM women. METHODS AND RESULTS Retrospective evaluation of women with HCM from 1970 to 2021. Only women with pregnancy-related information (pregnancy present or absent) and a follow-up period lasting ≥1 year were included. The peri-partum period was defined as -1 to 6 months after delivery. The primary endpoint was a composite for major adverse cardiovascular events [MACE: cardiovascular death, sudden cardiac death, appropriate defibrillator shock and heart failure (HF) progression]. Overall, 379 (58%) women were included. There were 432 pregnancies in 242 (63%) patients. In 29 (7.6%) cases, pregnancies (n = 39) occurred after HCM diagnosis. Among these, three carrying likely pathogenic sarcomeric variants suffered MACEs in the peri-partum period. At 10 ± 9 years of follow-up, age at diagnosis [hazard ratio (HR) 1.034, 95% confidence interval (CI) 1.018-1.050, P < 0.001] and New York Heart Association (NYHA) class (II vs. I: HR 1.944, 95% CI 0.896-4.218; III vs. I: HR 5.291, 95% CI 2.392-11.705, P < 0.001) were associated with MACE. Conversely, pregnancy was associated with reduced risk (HR 0.605; 95% CI 0.380-0.963, P = 0.034). Among women with pregnancy, multiple occurrences did not modify risk. CONCLUSIONS Pregnancy is not a modifier of long-term outcome in women with HCM and mostly occurs before a cardiac diagnosis. Most patients tolerate pregnancy well and do not show a survival disadvantage compared to women without. Pregnancy should not be discouraged, except in the presence of severe HF symptoms or high-risk features.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in adults, but first-line immunochemotherapy fails to produce a durable response in about one-third of the patients. Because tumor cells often reprogram their metabolism, we investigated the importance of glutaminolysis, a pathway converting glutamine to generate energy and various metabolites, for the growth of DLBCL cells. Glutaminase-1 (GLS1) expression was robustly detected in DLBCL biopsy samples and cell lines. Both pharmacological inhibition and genetic knockdown of GLS1 induced cell death in DLBCL cells regardless of their subtype classification, whereas primary B cells remained unaffected. Interestingly, GLS1 inhibition resulted not only in reduced levels of intermediates of the tricarboxylic acid cycle but also in a strong mitochondrial accumulation of reactive oxygen species. Supplementation of DLBCL cells with α-ketoglutarate or with the antioxidant α-tocopherol mitigated oxidative stress and abrogated cell death upon GLS1 inhibition, indicating an essential role of glutaminolysis in the protection from oxidative stress. Furthermore, the combination of the GLS1 inhibitor CB-839 with the therapeutic BCL2 inhibitor ABT-199 not only induced massive reactive oxygen species (ROS) production but also exhibited highly synergistic cytotoxicity, suggesting that simultaneous targeting of GLS1 and BCL2 could represent a novel therapeutic strategy for patients with DLBCL.

Abstract
BACKGROUND Cardiac involvement is reported in a significant proportion of patients with classical organic acidurias (OAs), contributing to disability and premature death. Different cardiac phenotypes have been described, among which dilated cardiomyopathy (DCM) is predominant. Despite recent progress in diagnosis and treatment, the natural history of patients with OAs remains unresolved, specifically with regard to the impact of cardiac complications. We therefore performed a retrospective study to address this issue at our Referral Center for Pediatric Inherited Errors of Metabolism. METHODS Sixty patients with OAs (propionic (PA), methylmalonic (MMA) and isovaleric acidemias and maple syrup urine disease) diagnosed from 2000 to 2022 were systematically assessed at baseline and at follow-up. RESULTS Cardiac anomalies were found in 23/60 OA patients, all with PA or MMA, represented by DCM (17/23 patients) and/or acquired long QT syndrome (3/23 patients). The presence of DCM was associated with the worst prognosis. The rate of occurrence of major adverse cardiac events (MACEs) at 5 years was 55% in PA with cardiomyopathy; 35% in MMA with cardiomyopathy; and 23% in MMA without cardiomyopathy. Liver transplantation was performed in seven patients (12%), all with PA or MMA, due to worsening cardiac impairment, and led to the stabilization of metabolic status and cardiac function. CONCLUSIONS Cardiac involvement was documented in about one third of children diagnosed with classical OAs, confined to PA and MMA, and was often associated with poor outcome in over 50%. Etiological diagnosis of OAs is essential in guiding management and risk stratification.

Abstract
BACKGORUND Hereditary transthyretin(vATTR) cardiac amyloidosis has extremely different features according to the type of transthyretin(TTR) mutation. Data about electrocardiographic findings(ECG) in vATTR are limited and not informative of genotype correlation. Aim of this study is to analyze ECG characteristics and their correlation to clinical and echocardiographic aspects in patients with vATTR, focusing on different TTR mutations. METHODS AND RESULTS This is a multicentric, retrospective, observational study performed in six Italian referral centres. We divided patients in two groups, according to the previously described phenotypic manifestations of the TTR mutation. Of 64 patients with vATTR, 23(36%) had prevalent cardiac(PC) TTR mutations and 41(64%) patients had a prevalent neurological(PN) TTR mutations. Patients with PC mutations were more frequently males and older, with advanced NAC staging. At baseline ECG, atrial fibrillation was more common in patients with PC, while pacemaker induced rhythm in PN mutations. PQ and QRS durations were longer and voltage to mass ratio was lower in PC mutations. Different TTR mutations tend to have distinctive ECG features. CONCLUSIONS ECG in vATTR is extremely heterogeneous and the specific mutations are associated with distinct instrumental and clinical features. The differences between PN and PC vATTR are only partially explained by the different degree of cardiac infiltration.

Abstract
Restrictive cardiomyopathy (RCM) is characterized by restrictive ventricular pathophysiology determined by increased myocardial stiffness. While suspicion of RCM is initially raised by clinical evaluation and supported by electrocardiographic and echocardiographic findings, invasive hemodynamic evaluation is often required for diagnosis and management of patients during follow-up. RCM is commonly associated with a poor prognosis and a high incidence of heart failure, and PH is reported in paediatric patients with RCM. Currently, only a few therapies are available for specific RCM aetiologies. Early referral to centres for advanced heart failure treatment is often necessary. The aim of this review is to address questions frequently asked when facing paediatric patients with RCM, including issues related to aetiologies, clinical presentation, diagnostic process and prognosis.

Abstract
BACKGROUND Data on the incidence and factors associated with de novo atrial fibrillation (AF) in patients with wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) is limited. We described the incidence and factors associated with de novo AF in patients diagnosed with ATTRwt-CA to drive tailored arrhythmia screening. METHODS Multicenter, retrospective, observational cohort study performed in six referral centers for CA. All consecutive patients diagnosed with ATTRwt-CA between 2004 and 2020 with >6-month follow up (FU) were enrolled and divided into three groups according to presence of AF: (1)patients with 'known AF'; (2)patients in 'sinus rhythm' and (3)patients developing 'de novo AF' during FU. Incidence and factors associated with AF in patients with ATTRwt were the primary outcomes. RESULTS Overall, 266 patients were followed for a median of 19 [11-33] months: 148 (56%) with known AF, 84 (31.6%) with sinus rhythm, and 34 (12.8%) with de novo AF. At Fine-Gray competing risk analysis to account for mortality, PR (sub-distribution hazard ratio [SHR] per Δms: 1.008, 95% C.I. 1.001-1.013, p = 0.008), QRS (SHR per Δms: 1.012, 95% C.I. 1.001-1.022, p = 0.046) and left atrial diameter ≥ 50 mm (SHR: 2.815,95% C.I. 1.483-5.342, p = 0.002) were associated with de novo AF. Patients with at least two risk factors (PR ≥ 200 ms, QRS ≥ 120 ms or LAD≥50 mm) had a higher risk of developing de novo AF compared to patients with no risk factors (HR 14.918 95% C.I. 3.242-31.646, p = 0.008). CONCLUSIONS At the end of the study almost 70% patients had AF. Longer PR and QRS duration and left atrial dilation are associated with arrhythmia onset.

Abstract
Hypertrophic cardiomyopathy is the most common genetic cardiomyopathy. Main complications include the development of arrhythmias and heart failure, and the latter may be triggered by left ventricular outflow tract obstruction. The treatment of left ventricular outflow tract obstruction includes pharmacological therapies (beta-blockers, calcium channel blockers, disopyramide) and septal reduction therapies (alcohol septal ablation, surgical myectomy). Myosin inhibitors represent a new therapeutic opportunity and in recent clinical trials proved effective in symptom relief, improvement of functional capacity and quality of life in patients with obstructive hypertrophic cardiomyopathy. In this narrative review we will summarize the available and under development therapeutic approaches for hypertrophic cardiomyopathy.

Abstract
Diffuse large B-cell lymphoma (DLBCL), the most common form of non-Hodgkin lymphoma, is characterized by an aggressive clinical course. In approximately one-third of patients with DLBCL, first-line multiagent immunochemotherapy fails to produce a durable response. Molecular heterogeneity and apoptosis resistance pose major therapeutic challenges in DLBCL treatment. To circumvent apoptosis resistance, the induction of ferroptosis might represent a promising strategy for lymphoma therapy. In this study, a compound library, targeting epigenetic modulators, was screened to identify ferroptosis-sensitizing drugs. Strikingly, bromodomain and extra-terminal domain (BET) inhibitors sensitized cells of the germinal center B-cell-like (GCB) subtype of DLBCL to ferroptosis induction and the combination of BET inhibitors with ferroptosis inducers, such as dimethyl fumarate or RSL3, synergized in the killing of DLBCL cells in vitro and in vivo. On the molecular level, the BET protein BRD4 was found to be an essential regulator of ferroptosis suppressor protein 1 expression and thus to protect GCB-DLBCL cells from ferroptosis. Collectively, we identified and characterized BRD4 as an important player in ferroptosis suppression in GCB-DLBCL and provide a rationale for the combination of BET inhibitors with ferroptosis-inducing agents as a novel therapeutic approach for DLBCL treatment.

Abstract
Recent evidence from imaging and genetic screening studies has clearly shown that hypertrophic cardiomyopathy (HCM) is more common than initially perceived, emphasizing the need to reassess its associated clinical and social burden. While clinical and academic efforts have long been focused on stratification of arrhythmic risk and management of intraventricular obstruction, progression of cardiac dysfunction and heart failure-related complications have emerged as most relevant from the epidemiological standpoint, delineating a major unmet need. Furthermore, a broader perspective of our patients' needs has become central in the care of individuals with HCM, addressing issues that are not strictly clinical but equally important to their wellbeing, such as quality of life, athletic participation, lifestyle and reproductive choices and psychological adaptation to a chronic condition often detected at a young age. The appropriate evaluation and objective assessment of disease burden associated with HCM are increasingly relevant not only to management but also to trial design and evaluation of the efficacy of emerging, targeted treatments. In this review, we discuss the evolving perception of HCM prevalence and natural history, as well as recent acquisitions regarding its true, often under-appreciated socio-economic and clinical burden.

Abstract
INTRODUCTION Patients with hypertrophic cardiomyopathy (HCM) are at increased risk of stroke, but the incidence and factors associated with cardioembolic events in HCM patients without atrial fibrillation (AF) remain unresolved. We determined the incidence of stroke in patients in sinus rhythm (SR) monitored with a cardiac implantable electronic device (CIED). METHODS All consecutive patients diagnosed with HCM and referred to CIED implantation with >16 years at diagnosis and ≥ 1 year follow-up post CIED implantation were retrospectively reviewed. Severe LA dilatation was defined as ≥48 mm. Patients were stratified by rhythm as: Pre-existing AF (AF present prior to CIED); De novo AF (AF present after CIED implantation); SR: no episodes of AF. RESULTS Of 1651 patients, 185 (11.2%) implanted with a CIED were included (57% men, age: 54 ± 17 years). Baseline, pre-existing AF was present in 73 (39%) patients. Ischemic stroke was reported in 19 (10.3%, 1.78%/year) patients and was similar across the three groups (2.3%/year vs 1.1%/year vs 0.6%/year in patients in SR vs pre-existing AF vs de novo AF, respectively, p = 0.235). In SR patients, a LAD≥48 mm posed the greatest risk of stroke (Hazard Ratio: 10.03,95% Confidence-Interval 2.79-16.01). At Cox multivariable analysis, after adjustment for oral anticoagulation, LA was independently associated with stroke while rhythm was not. CONCLUSIONS in HCM patients with CIED long-term monitoring and no prior history of AF, stroke rates were similar in those with de novo AF or stable SR. Severe LA dilatation was a powerful risk factor, irrespective of AF.

Abstract
Hypertrophic cardiomyopathy (HCM) is the most common inherited myocardial disease and is defined by otherwise unexplained left ventricular hypertrophy. The main complications include heart failure and arrhythmias such as atrial fibrillation and ventricular arrhythmias. Current treatment rests on septal reduction therapies, prevention of sudden cardiac death through implantable cardioverter defibrillator, and use of drugs such as beta-blockers, calcium antagonists, or amiodarone. In the last years, new pharmacological agents specifically targeting the pathophysiology of the disease have been developed with encouraging results in terms of functional capacity and symptoms improvement from clinical trials. In this review, we summarize the possible treatment approaches for each phase of the natural history of the disease: pre-phenotype expression, classic phenotype, adverse remodelling, and overt dysfunction.

Abstract
The p.Val142Ile variant in transthyretin (encoded by the TTR gene) is the most common genetic cause of transthyretin-related amyloidosis. This allele is particularly prevalent in communities ofAfrican descent compared with populations of different ancestries, where its frequency is two orders of magnitude lower. For this reason, p.Val142Ile has always been considered an "African" variant, with limited studies performed on individuals of European descent. However, recent reports of higher-than-expected prevalence in European-ancestry populations question the African specificity of this allele. Here we show that the high recurrence of p.Val142Ile in central Italy is due to a founder effect and not to recent admixture from African populations, highlighting how this may be the case in other communities. This suggests a probable underestimate of the global prevalence of p.Val142Ile, and further emphasizes the importance of routine inclusion of TTR in gene panels used for clinical genetic testing in hypertrophic cardiomyopathy (independently of the patient's geographical origin), that transthyretin-related amyloidosis can mimic.

Abstract
Genetic counselling and genetic testing in hypertrophic cardiomyopathy (HCM) represent an integral part of the diagnostic algorithm to confirm the diagnosis, distinguish it from phenocopies, and suggest tailored therapeutic intervention strategies. Additionally, they enable cascade genetic testing in the family. With the implementation of Next Generation Sequencing technologies (NGS), the interpretation of genetic data has become more complex. In this regard, cardiologists play a central role, aiding geneticists to correctly evaluate the pathogenicity of the identified genetic alterations. In the ideal setting, geneticists and cardiologists must work side by side to diagnose HCM as well as convey the correct information to patients in response to their many questions and concerns. After a brief overview of the role of genetics in the diagnosis of HCM, we present and discuss the frequently asked questions by HCM patients throughout our 20-year genetic counselling experience. Appropriate communication between the team and the families is key to the goal of delivering the full potential of genetic testing to our patients.

Abstract
AIMS To perform evaluation of widely embraced bone scintigraphy-based non-biopsy diagnostic criteria (NBDC) for ATTR amyloid cardiomyopathy (ATTR-CM) in clinical practice, and to refine serum free light chain (sFLC) ratio cut-offs that reliably exclude monoclonal gammopathy (MG) in chronic kidney disease. METHODS AND RESULTS A multi-national retrospective study of 3354 patients with suspected or histologically proven cardiac amyloidosis (CA) referred to specialist centres from 2015 to 2021; evaluations included radionuclide bone scintigraphy, serum and urine immunofixation, sFLC assay, eGFR measurement and echocardiography. Seventy-nine percent (1636/2080) of patients with Perugini grade 2 or 3 radionuclide scans fulfilled NBDC for ATTR-CM through absence of a serum or urine monoclonal protein on immunofixation together with a sFLC ratio falling within revised cut-offs incorporating eGFR; 403 of these patients had amyloid on biopsy, all of which were ATTR type, and their survival was comparable to non-biopsied ATTR-CM patients (p = 0.10). Grade 0 radionuclide scans were present in 1091 patients, of whom 284 (26%) had CA, confirmed as AL type (AL-CA) in 276 (97%) and as ATTR-CM in only one case with an extremely rare TTR variant. Among 183 patients with grade 1 radionuclide scans, 122 had MG of whom 106 (87%) had AL-CA; 60/61 (98%) without MG had ATTR-CM. CONCLUSION The NBDC for ATTR-CM are highly specific [97% (95% CI 0.91-0.99)] in clinical setting, and diagnostic performance was further refined here using new cut-offs for sFLC ratio in patients with CKD. A grade 0 radionuclide scan all but excludes ATTR-CM but occurs in most patients with AL-CA. Grade 1 scans in patients with CA and no MG are strongly suggestive of early ATTR-type, but require urgent histologic corroboration.

Abstract
AIM Epidemiology of wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) remains poorly defined. A better characterization of pathways leading to ATTRwt-CA diagnosis is of key importance, and potentially informative of disease course and prognosis. The aim of this study was to describe the characteristics of contemporary pathways leading to ATTRwt-CA diagnosis, and their potential association with survival. METHODS AND RESULTS This was a retrospective study of patients diagnosed with ATTRwt-CA at 17 Italian referral centres for CA. Patients were categorized into different 'pathways' according to the medical reason that triggered the diagnosis of ATTRwt-CA (hypertrophic cardiomyopathy [HCM] pathway, heart failure [HF] pathway, incidental imaging or incidental clinical pathway). Prognosis was investigated with all-cause mortality as endpoint. Overall, 1281 ATTRwt-CA patients were included in the study. The diagnostic pathway leading to ATTRwt-CA diagnosis was HCM in 7% of patients, HF in 51%, incidental imaging in 23%, incidental clinical in 19%. Patients in the HF pathway, as compared to the others, were older and had a greater prevalence of New York Heart Association (NYHA) class III-IV and chronic kidney disease. Survival was significantly worse in the HF versus other pathways, but similar among the three others. In multivariate model, older age at diagnosis, NYHA class III-IV and some comorbidities but not the HF pathway were independently associated with worse survival. CONCLUSIONS Half of contemporary ATTRwt-CA diagnoses occur in a HF setting. These patients had worse clinical profile and outcome than those diagnosed either due to suspected HCM or incidentally, although prognosis remained primarily related to age, NYHA functional class and comorbidities rather than the diagnostic pathway itself.

Abstract
The evolving epidemiology of hypertrophic cardiomyopathy (HCM) has progressively changed our perception of HCM-related mortality. However, recent studies detailing individual causes of death based on age and clinical setting are lacking. Thus, the present study aimed to describe the modes of death in a consecutive cohort of HCM patients based on presenting clinical features and stage of disease. METHODS By retrospective analysis of a large HCM cohort, we identified 161 patients with >1 year follow-up who died between 2000 and 2020 and thoroughly investigated their modes of death. HCM stage at presentation was defined as "classic", "adverse remodeling" or "overt dysfunction". RESULTS Of the 161 patients, 103 (64%) died of HCM-related causes, whereas 58 (36%) died of non-HCM-related causes. Patients who died of HCM-related causes were younger than those who died of non-HCM related causes. The most common cause of death was heart failure (HF). Sudden cardiac death (SCD) ranked third, after non cardiovascular death, and mostly occurred in young individuals. The proportion of HF related death and SCD per stage of disease was 14% and 27% in "classic", 38% and 21% in "adverse remodeling" and 74% and 10% in "overt dysfunction". CONCLUSIONS Most HCM patients die due to complications of their own disease, mainly in the context of HF. While SCD tends to be juvenile, HF related deaths often occur in age groups no longer amenable to cardiac transplant. Modes of death vary with the stage of disease, with SCD becoming less prevalent in more advanced phases, when competitive risk of HF becomes overwhelming.

Abstract
The aim of this study is to evaluate the prognostic value of cardiopulmonary testing (CPET) in a cohort of patients with transthyretin cardiac amyloidosis (ATTR-CA). ATTR-CA is associated with a progressive reduction in functional capacity. The prognostic role of CPET parameters and in particular of normalized peak VO2 (%ppVO2) remains to be thoroughly evaluated. In this study, 75 patients with ATTR-CA underwent cardiological evaluation and CPET in a National Referral Center for cardiac amyloidosis (Careggi University Hospital, Florence). Fifty-seven patients (76%) had wild-type ATTR. Median age was 80 (75-83) years, 68 patients (91%) were men. Peak oxygen consumption (14.1 ± 4.1 ml/kg/min) and %ppVO2 (68.4 ± 18.8%) were blunted. Twenty-seven (36%) patients had an abnormal pressure response to exercise. After a median follow-up of 25 (12-31) months, the composite outcome of death or heart failure hospitalization was registered in 19 (25.3%) patients. At univariate analysis %ppVO2 was a stronger predictor for the composite outcome than peak VO2. %ppVO2 and NT-proBNP remained associated with the composite outcome at multivariate analysis. The optimal predictive threshold for %ppVO2 was 62% (sensitivity: 71%; specificity: 68%; AUC: 0.77, CI 0.65-0.88). Patients with %ppVO2 ≤ 62%and NT-proBNP > 3000 pg had a worse prognosis with 1- and 2-year survival of 69 ± 9% and 50 ± 10%, respectively. CPET is a safe and useful prognostic tool in patients with ATTR-CA. CPET may help to identify patients with advanced disease that may benefit from targeted therapy.

Abstract
Patients with ATTR cardiac amyloidosis (ATTR-CA) face rare disease that could negatively influence psychological well-being with consequences on the course of the disease and quality of life. However, to date, no study analyzed the prevalence of anxiety and depression in patients with ATTR-CA and which clinical and sociodemographic characteristics are linked with these psychopathological conditions. A total of 109 consecutive patients (83% males) aged 62-90 years with ATTR-CA were recruited. In order to better understand the prevalence of anxiety and depression in ATTR-CA, a control group composed by 33 individuals equaling gender, education, and age were recruited. The level of anxiety and depression was measured using the Italian version of the Hospital Anxiety and Depression Scale (HADS). Sociodemographic and clinic characteristics were registered. Almost half of patients (49%) reported a clinical level of depression or anxiety, or both. ATTR-CA patients reported higher levels of anxiety and depression than control group. Results showed that older patients with ATTR-CA, especially females, with more advanced disease could be more at risk to develop an anxious disorder. Furthermore, being a woman, and presenting with a greater severity of symptoms, would appear to be a risk factor for developing a depressive disorder. Overall, these results highlighted the high presence of anxiety and depression in ATTR-CA patients, suggesting to physicians to pay attention to the psychological well-being of ATTR-CA patients. In fact, a psychological support for patients with high level of psychopathological disease could reduce disease burden and improve quality of life in ATTR-CA population.

Abstract
OBJECTIVES We assessed the efficacy and safety of ranolazine in real-world patients with hypertrophic cardiomyopathy (HCM). BACKGROUND Ranolazine is an anti-anginal drug that inhibits the late phase of the inward sodium current. In a small prospective trial, ranolazine reduced the arrhythmic burden and improved biomarker profile in HCM patients. However, systematic reports reflecting real-world use in this setting are lacking. METHODS Changes in clinical and instrumental features, symptoms and arrhythmic burden were evaluated in 119 patients with HCM before and during treatment with ranolazine at a national referral centre for HCM. RESULTS Patients were treated with ranolazine for 2 [1-4] years; 83 (70%) achieved a dosage ≥1000 mg per day. Treatment interruption was necessary in 24 patients (20%) due to side effects (n = 10, 8%) or disopyramide initiation (n = 8, 7%). Seventy patients (59%) were treated with ranolazine for relief of angina. Among them, 51 (73%) had total symptomatic relief and 47 patients (67%) showed ≥2 Canadian Cardiovascular society (CCS) angina grade improvement. Sixteen patients (13%) were treated for recurrent ventricular arrhythmias, including 4 with a clear ischemic trigger, who experienced no further arrhythmic episodes while on ranolazine. Finally, 33 patients (28%) were treated for heart failure associated with severe diastolic dysfunction: no symptomatic benefit could be observed in this group. CONCLUSION Ranolazine was safe and well tolerated in patients with HCM. The use of ranolazine may be considered in patients with HCM and microvascular angina.

Abstract
Abstract
Background
The prevalence and course of heart failure (HF) in arrhythmogenic cardiomyopathy (ACM) is unresolved, and previous studies have mostly focused on the right-dominant variant of the disease, less prone to HF. Conversely, ACM variants with left ventricular (LV) involvement are now increasingly recognized, often initially ‘mis-diagnosed’ as dilated cardiomyopathy. Aim of this study was therefore to describe the prevalence and clinical course of advance HF in the full clinical spectrum of ACM.
Methods
We retrospectively reviewed records of all ACM patients diagnosed before 2021 from 3 Italian Cardiomyopathy Referral Centres (Azienda Ospedaliero Universitaria Careggi; Policlinico Sant’Orsola; Azienda Ospedaliero Universitaria Sant’Andrea). LV involvement was diagnosed in the presence of subepicardial late gadolinium enhancement (LGE) in at least 3 contiguous segments in the same short-axis slice at cardiac magnetic resonance, independent of whether it fulfilled the 2010 Task Force criteria for right-dominant ACM (biventricular ACM) or not (left-dominant ACM); in this latter case, diagnosis was reached after careful exclusion of other differential diagnosis, and only when at least one of the following features was present: likely pathogenic/pathogenic genetic variant associated with ACM; familial history of ACM; electrocardiographic abnormalities suggestive of ACM with LV involvement. Advanced HF was defined as NYHA functional class III/IV and/or referral for heart transplantation. Median follow-up was 6 years.
Results
Forty-four out of 174 ACM patients (25%) developed advanced HF: 10 right-dominant ACM and 34 with LV involvement. Twenty ACM patients were initially diagnosed with dilated cardiomyopathy; as such, development of advanced HF in 17 cases preceded the diagnosis of ACM. Five patients were diagnosed with ACM after heart transplantation, by histological examination. In the other 22, median time from ACM diagnosis to advanced HF development was 4 years. As compared to those without, advanced HF patients were more likely to present LV involvement. During clinical course, 20 (46%) advanced HF patients received at least one appropriate ICD intervention, with 13 experiencing an electrical storm. Twenty-six (59%) patients required HF-related hospitalization, and 32 (72%) were referred for heart transplantation with 25 ultimately receiving it. ACM patients with advanced HF, compared to those without, experienced a higher rate of mortality (36% vs. 6%; OR 3.5 [95%CI: 1.4-8.7], p=0.01) and ventricular arrhythmic events (41% vs. 11%; OR 2.4 [95%CI: 1.1-5.0], p=0.02).
Conclusions
Advanced HF progression in ACM is not rare, and occurs more frequently in variants with LV involvement. Advanced HF is associated with increased mortality and arrhythmic risk.

Abstract
Abstract
Background
Hypertrophic Cardiomyopathy (HCM) is the most common genetic cardiomyopathy. However, few studies have systematically investigated the clinical course of pregnancy in hypertrophic cardiomyopathy (HCM).
Purpose
To assess whether pregnancy or baseline symptoms at diagnosis or both could drive long-term prognosis in terms of HCM-related events ranging from heart failure to life-threatening arrhythmias and cardiovascular death.
Methods
Women consecutively referred to our Tertiary Clinic for Cardiomyopathies from 1969 to 2019 were retrospectively reviewed. Only women with complete data regarding pregnancy and with a follow up (FU)≥1 year were included in the study. Overall, of the 647 women followed at our center and 378 (58%) fulfilled our inclusion criteria. The peripartum period was defined as the timeframe from -1 to 6 months after delivery. The primary endpoint were major adverse cardiovascular events (MACE: cardiovascular (CV) death, sudden cardiac death (SCD), ICD appropriate shock, and progression of heart failure) at follow-up.
Results
There were 432 pregnancies in 239 (63%) women with 132(62%) having >1 pregnancy. A total of 139(37%) reported no pregnancy. Twenty-nine (7.6%) women had 39 pregnancies after HCM diagnosis and were followed by the obstetrics department. Instrumental characteristics were comparable among women. Thirty percent presented with obstructive physiology at baseline. Among the 39 pregnancies in women who had a pregnancy after the diagnosis, there were 3 MACEs in the peripartum period (1 cardiac arrest, 1 sustained ventricular tachycardia and 1 episode of acute heart failure). Of note, the three women had a likely pathogenic genetic variant on the TNNI3, TNNT2 and MYH7 genes.
Long-term (FU: 10±9 years), at Cox multivariable analysis, after correction for obstructive physiology and LA diameter, pregnancy (Hazard Ratio [HR]: 0.605, 95% Confidence Interval [C.I.] 0.380-0.963, p=0.034), age at diagnosis (HR: 1.034, 95% C.I. 1.018-1.050, p<0.001) and NYHA Class (II vs I: HR 1.944, 95% C.I 0.896-4.218; III vs I: HR 5.291, 95% C.I. 2.392-11.705, overall p<0.001) were associated with MACE. NYHA class also proved to be a predictor for MACE in women with pregnancy (II vs I: HR 1.200, 95% C.I 0.463-3.106; III vs I: HR 3.040, 95% C.I. 1.062-8.705, overall p=0.022). Notably, in this group, number of pregnancies was not associated with unfavorable outcome (HR: 1.170, 95% C.I. 0.593-2.308, p=0.650).
Age and symptoms were also associated with MACE in women without pregnancy.
Conclusions
Women with HCM tolerate pregnancy well. Although rare, adverse events during the peripartum period may arise and the risk should be discussed during ante-natal counselling. Age and NYHA class were the main drivers of long-term outcome. These findings suggest that while pregnancy can be safely pursued there is a need for close monitoring for heart failure symptoms prior to and during pregnancy.

Abstract
Transthyretin (TTR) amyloid cardiomyopathy due to mutation on TTR gene (vATTR) has extremely different features according to the type of mutation, ranging from a mild to an extensive cardiac involvement. Data about electrocardiographic findings (ECG) in vATTR are limited and not informative of genotype correlation. Aim of this study is to analyze ECG characteristics and their correlation to clinical and echocardiographic aspects in patients with vATTR cardiomyopathy, focusing on different TTR mutations.
This is a multicentric, retrospective, observational study performed in six Italian referral centres for cardiac amyloidosis. We divided patients in two groups, according to the previously described phenotypic manifestations of the TTR mutation. Of 64 patients with vATTR cardiomyopathy, 23 (36%) had prevalent cardiac (PC) TTR mutations and 41 (64%) patients had a prevalent neurological (PN) TTR mutations. Patients with PC mutations were more frequently males and older, with advanced NAC staging. At baseline ECG, atrial fibrillation was more common in patients with PC, while pacemaker induced rhythm in those with PN mutations. Prevalence of atrioventricular and intraventricular blocks, pseudonecrosis pattern and low voltages were not significantly different in both groups. PQ and QRS durations were longer and voltage to mass ratio was lower in PC mutations. Different TTR mutations tend to have distinctive ECG features.
The standard ECG in vATTR is extremely heterogeneous and the specific mutations are associated with distinct instrumental and clinical features. The differences between PN and PC vATTR are only partially explained by the different degree of cardiac infiltration.

Abstract
Abstract
Introduction
Cardiotoxicity involves direct effects of cancer related treatment on heart function, commonly presenting as left ventricular contractile dysfunction. However, limited data are available regarding cardiotoxicity on hypertrophic cardiomyopathy (HCM), because most studies and registries have not specifically analyzed the effects of oncological treatment in HCM populations. This gap in knowledge may lead to unjustified restriction of HCM patients to radical cancer treatments.
Aim
We aimed at describing the potential clinical cardiotoxicity of oncological treatments in a cohort of consecutive HCM patients, systematically followed up at two national referral centres for HCM.
Methods
We retrospectively analysed all clinical and instrumental data of all consecutive HCM patients who underwent oncological treatment between January 2000 and December 2020, collected in a centralized database.
Results
Of 3256 HCM patients, 121 (3.7%) had a reported diagnosis of cancer; 109 (90.1%) patients underwent oncological surgery, 45 (37.2%) chemotherapic treatment, 22 (18.2%) chest radiotherapy. After a median follow up of 5 (2-13) years from oncological diagnosis, 32 of the 121 patients (26.4%) died. The cause of death was mainly attributed to the oncological condition, while 4 (12.5%) patients died of sudden cardiac death without previous chemotherapy or chest radiotherapy.
No patient interrupted or reduced the dose of oncological treatment due to cardiac dysfunction. No sustained ventricular tachyarrhythmia was induced by chemotherapy or radiotherapy.
Conclusions
Cancer treatment is well tolerated in HCM patients. In our oncology series, none died of cardiovascular complications induced by chemotherapy or chest radiotherapy and none required interruption or substantial tapering of treatment due to cardiovascular side effects. Although expert multidisciplinary evaluation is mandatory and regimens must be tailored individually, the diagnosis of HCM per se should not be considered a contraindication to radical cancer treatment.

Abstract
Abstract
Background
ATTR-CA is associated with a progressive reduction in functional capacity. The prognostic role of CPET parameters and in particular of normalized peak VO2 (%ppVO2) remains to be thoroughly evaluated.
Methods
In this study 75 patients with ATTR-CA underwent cardiological evaluation and CPET in a National Referral Center for cardiac amyloidosis (Careggi University hospital, Florence).
Results
Fifty-seven patients (76%) had wild type ATTR. Median age was 80 (75-83) years, 68 patients (91%) were men. Peak oxygen consumption (14.1±4.1 ml/kg/min) and %ppVO2 (68.4±18.8%) were blunted. Twenty-seven (36%) patients had an abnormal pressure response to exercise. After a median follow-up of 25 (12-31) months the composite outcome of death or heart failure hospitalization was registered in 19 (25.3%) patients. At univariate analysis %ppVO2 was a stronger predictor for the composite outcome than peak VO2. %ppVO2 and NTproBNP remained associated with the composite outcome at multivariate analysis. The optimal predictive threshold for %ppVO2 was 62% (sensitivity: 71%; specificity: 68%; AUC:0.77, CI: 0.65-0.88). Patients with %ppVO2 ≤ 62%and NTproBNP >3000pg had the worse prognosis with 1- and 2-year survival of 69±9% and 50±10%, respectively.
Conclusions
CPET is a safe and useful prognostic tool in patients with ATTR-CA. CPET may help to identify patients with advanced disease that may benefit of targeted therapy.

Abstract
Abstract
Background
Hypertrophic cardiomyopathy (HCM), being characterized by enhanced contractility, positively responses to treatment with myosin inhibitors which could promote reverse remodelling. Additionally, speckle tracking analysis highlights left ventricular (LV) contractile alterations in HCM, although the pathophysiological meaning and the effect of the target-therapy are still unclear.
Aim
To analyse global and regional longitudinal peak systolic strain in patients with HCM in comparison to age-matched control group without HCM and with known coronary artery anatomy.
Methods
We examined 37 HCM patients (33 with asymmetric septal and 4 with apical hypertrophy) and 67 age-matched controls without HCM or significant coronary stenoses, with transthoracic echocardiography with analysis of segmental and global left ventricular strain (GLS) by AFI method in 16-segment LV model.
Results
Patients with HCM showed higher values of interventricular septal thickness, left atrial diameter and LV ejection fraction, whereas controls presented higher BMI and resting heart rate. In deformation analysis, GLS values were lower in HCM (15.9 ± 4.2 vs 18.4 ± 3.5%, p = 0.002) as well as segmental strain was significantly impaired in marker regions for studied form of HCM, in particular septal, inferior and inferolateral basal and mid segments as well as apical inferior segment for HCM with asymmetric septal hypertrophy; 4 patients with apical form of HCM showed severely impaired strain in all apical segments.
Conclusions
Deformation analysis shows a significant impairment of global and segmental strain values in patients with HCM, in particular for hypertrophic segments. This finding does not definitely imply a certain contractile dysfunction, and further investigation on the effect of myosin inhibitors on strain analysis is strongly recommended.

Abstract
Abstract
Purpose
We described the incidence and ECG factors associated with de novo atrial fibrillation (AF) in patients diagnosed with wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) to drive tailored arrhythmia screening.
Background
Data on the incidence rate and factors associated with de novo AF in patients with ATTRwt CA is limited.
Methods
Multicenter, retrospective, observational cohort study performed in six referral centers for CA. All consecutive patients diagnosed with ATTRwt-CA between 2004 and 2020 with >1-year follow up (FU) were enrolled in the study and were divided into three groups according to presence of AF: (1)patients with ‘known AF’; (2)patients in ‘sinus rhythm’ and (3)patients developing ‘de novo AF’ during FU. Incidence and factors associated with AF in patients with ATTRwt were the primary outcomes.
Results
Overall, 266 patients were followed for a median of 469 days: 148 (56%) with known AF, 84 (31.6%) with sinus rhythm, and 34 (12.8%) with de novo AF. Age and gender were similarly distributed. At multivariable analysis, PR (Hazard Ratio[HR]: 1.008 95% C.I. 1.001-1.016), QRS (HR: 1.022 95% C.I. 1.002-1.043) and left atrial dilatation>50mm (HR: 3.429 95% C.I. 1.565-7.329) were associated with de novo AF at FU. Patients presenting with at least two risk factors (PR>200ms, QRS>120ms or LAD>50mm) had a higher risk of developing de novo AF compared to patients with no risk factors (HR 14.918 95% C.I. 3.242-31.646).
Conclusions
Incidence of de novo AF in patients with ATTRwt is 20.7%/year. Longer PR and QRS duration and left atrial dilation are associated with arrhythmia onset.

Abstract
Abstract
The p.Val142Ile variant in transthyretin (encoded by the TTR gene) is the most common genetic cause of transthyretin-related amyloidosis. This allele is particularly prevalent in communities of African descent compared with populations of different ancestries, where its frequency is two orders of magnitude lower. For this reason, p.Val142Ile has always been considered an “African” variant, with limited studies performed on individuals of European descent. However, recent reports of higher-than-expected prevalence in European-ancestry populations question the African specificity of this allele. Here we show that the high recurrence of p.Val142Ile in central Italy is due to a founder effect and not to recent admixture from African populations, highlighting how this may be the case in other communities. This suggests a probable underestimate of the global prevalence of p.Val142Ile, and further emphasizes the importance of routine inclusion of TTR in gene panels used for clinical genetic testing in hypertrophic cardiomyopathy (independently of the patient's geographical origin), that transthyretin-related amyloidosis can mimic. Figure.Principal Component Analysis (PCA) of the 16 probands together with the 25044 individuals of the 1000 Genomes Project (Phase 3) having been genotyped both within the 1000 Genomes Project (NA10851_1KG) and in-house (NA10851_internal). The proband clustering within the smear of native Americans is A228.

Abstract
Abstract
Aims
The prognostic role of bone tracer uptake in transthyretin cardiac amyloidosis (ATTR-CA) is controversial. The study investigated the potential prognostic significance of biventricular (BiV) uptake in ATTR-CA.
Methods
Consecutive ATTR-CA patients who had cardiac scintigraphy with acquisition of planar and single-photon emission computed tomography (SPECT) images from the National Amyloidosis Centre (NAC) and four Italian centres were included. Planar BiV uptake was defined in presence of right ventricle (RV) uptake and graded in combination with SPECT imaging. The primary outcome was all-cause mortality.
Results
Among 1422 patients with ATTR-CA, BiV uptake was found in 85% of cases on planar scintigraphy and in 100% of cases on SPECT images. During a median follow-up of 39 months, BiV uptake at planar scintigraphy was associated with a higher all-cause mortality compared to isolated LV uptake (40.5% vs 10.7%, p<0.001), whereas the Perugini scale was not (p=0.27 in grade 2 vs 3). At multivariable analysis, RV uptake at planar scintigraphy leading to BiV uptake (HR 2.80, p=0.001), together with higher age at diagnosis (HR 1.03, p=0.001), V122I TTR variant (HR 1.60, p=0.001), NAC ATTR Stage (HR 1.29, p=0.003), E/e’ (HR 1.02, p=0.044), right atrium area index (HR 1.04, p=0.018) and GLS (HR 1.05, p=0.003) were independently associated with all-cause death. At time-dependent ROC curve analysis, the addition of planar BiV uptake to the NAC stage resulted in improved accuracy of the model for prediction of all-cause death (from AUC 0.74 to 0.79; p<0.001).
Conclusions
Planar RV uptake leading to BiV uptake identified ATTR-CA patients with worse outcome, potentially serving as a novel prognostic marker.

Abstract
Abstract
Introduction
Whether obesity, a modifiable risk factor in patients with hypertrophic cardiomyopathy (HCM), can influence coronary microvascular dysfunction (CMD) is unknown.
Objective
To assess the relationship between body weight and CMD measured with myocardial blood flow (MBF) at positron emission tomography (PET) in patients with HCM.
Methods
All consecutive patients with HCM referred to PET scan from 2010 to 2020 were reviewed. Only patients with PET and cardiac magnetic resonance (CMR) analysis, <60 years old at diagnosis, with no history of diabetes, dyslipidemia, and hypertension were included.
Patients were classified into three groups according to baseline BMI: BMI<25 kg/m2, BMI 25-30 kg/m2, and BMI>30 kg/m2.
Results
Of 1512 patients with HCM, 134 (8.9%) had been referred to a PET scan and 79 (5.2%) met the inclusion criteria (29% were women, median age was 44 [28-53] years). Overall, 52% had a BMI<25 kg/m2, 37% had a BMI 25-30 kg/m2, and 11% had a BMI >30 kg/m2.
At PET, average MBF was 2.08 [1.52-2.40] ml/min/g and was similar among BMI groups (p=0.288) irrespective of fibrosis at CMR. Prevalence of severe microvascular dysfunction was similar (MBF <1.53 ml/min/g: (9 [22%] vs 8 [28%] vs 2 [22%], among study groups, p=0.833). Age at PET and atrial fibrillation were associated with MBF.
Conclusions
Obesity is not associated with worsening of CMD in HCM patients. These findings support the hypothesis that the worse symptomatic profile in obese HCM patients is due to increased prevalence of obstruction rather than accentuation of structural phenotype. Thus, the symptomatic handicap associated with obesity may be reversible following appropriate weight-reduction strategies

Abstract
Cardiac amyloidosis (CA), caused by the deposition of insoluble amyloid fibrils, impairs different cardiac structures, altering not only left ventricle (LV) systo-diastolic function but also atrial function and the conduction system. The consequences of the involvement of the cardiac electrical system deserve more attention, as well as the study of the underlying molecular mechanisms. This is an issue of considerable interest, given the conflicting data on the effectiveness of conventional antiarrhythmic strategies. Therefore, this review aims at summarizing the arrhythmic burden related to CA and the available evidence on antiarrhythmic treatment in this population.

Abstract
Abstract
Background
Patients with hypertrophic cardiomyopathy (HCM) are at increased risk of atrial fibrillation (AF) and stroke, especially at an advanced disease stage. To date, however, the incidence and factors associated with cardioembolic events in HCM patients without AF remain unresolved.
Purpose
To determine the incidence of stroke in HCM patients in whom cardiac rhythm was monitored with a cardiac implantable electronic device (CIED). The association of stroke with left atrial (LA) enlargement was also examined.
Methods
Retrospective cohort study in an outpatient clinic in a tertiary HCM Referral Center.
All consecutive patients diagnosed with HCM and referred for CIED implantation with >16 years at diagnosis and >1 year follow-up post CIED implantation were reviewed. Severe LA dilatation was defined as a LA dimension (LAD) of >48mm at echocardiogram. Based on CIED monitoring, patients were classified as: Pre-existing AF (diagnosed with AF prior to CIED); De novo AF (diagnosed with AF after CIED implantation); Sinus Rhythm (SR): no episodes of AF. Incidence of stroke after CIED implantation was the primary outcome.
Results
A total of 185 patients (57% men, age: 54±17 years) were implanted with a CIED and were included. Pre-existing AF was present in 72 (36%) patients and de novo AF in 24 (13%); whereas 89 (48%) remained in SR. After 5 [2–9] years, stroke was reported in 19 (10.3%) patients: 7 occurred in patients with pre-existing AF (1.1%/year), 3 in patients with de novo AF (2.2%/year), and 9 in patients with SR (2.3%/year). No difference was captured by CHA2DS2-VASc score among rhythm categories. Patients with AF had larger LAD at baseline. Among patients in SR, those with a LAD>48mm had the greatest risk of stroke (4.8%/year vs 0.5%/year, p<0.01; Hazard Ratio [HR]: 8.56, 95% C.I. 2.03–36.15). At Cox multivariable regression analysis, LA (HR: 1.104, 95%C.I. 1.039–1.173, p=0.001) and AF (HR: 0.310, 95% C.I. 0.102–0.939, p=0.038) were associated with incident stroke.
Conclusions
In HCM patients with CIED long-term monitoring and no prior history of AF, stroke rates were similar in those with de novo AF or stable sinus rhythm. CHA2DS2-VASc considerably underestimated risk, whereas severe LA dilatation was a powerful predictor of risk, irrespective of AF.

Abstract
Abstract
In the early days, Hypertrophic cardiomyopathy (HCM) has long been considered a malignant disease.
However, contemporary descriptions of HCM report low mortality rates, largely due to heart failure-related complications (HF), while sudden cardiac death (SCD) rates are consistently low. Ageing with HCM is not uncommon and competing risk of acquired cardiovascular (CV) and non-CV diseases becomes relevant over time.
Purpose
To describe the disease stage at presentation and the modes of death in a cohort of consecutive HCM patients followed at a national referral centre over the last two decades. Stages of disease were defined according to Circ. Heart Fail. 2012, as follows:
1) “Classic HCM phenotype” characterized by LV ejection fraction (EF) >65%.
2) “Adverse remodeling” characterized by LVEF in the range of 50% to 65%.
3) “Overt dysfunction” is the end-stage clinical evolution characterized by a LVEF <50%.
Methods
By searching our centralized database, we identified 1491 HCM patients with at least >1 year of follow-up between January 2000 and December 2020, 191 of whom died in the same period. In 30 the cause of death could not be ascertained. The remaining 161 constituted our study cohort.
Results
Of the 161 patients who died, 103 (64%) died due to HCM-related causes, whereas 58 (36%) died from non-HCM-related causes such as coronary artery disease (other CV) or other non CV causes.
Modes of death varied based on the stage of disease at diagnosis:
– Fifty-six (35%) patients had a “classic” HCM phenotype at diagnosis. Of these, about half died of HCM-related causes (n=30; 54%), versus 45% with non-HCM-related death. Differently from the other 2 stages, the single most common cause of death was “other non-CV related” mortality, in 44%. Among HCM-related causes, SCD prevailed (n=15; 27%) while HF-related events were only 8 (14%).
– Of the 86 (53%) patients with “adverse remodeling” at diagnosis, more than half died of HCM-related causes (n=57, 66%), largely due to HF (n=33, 38%); SCD occurred in 18 (21%) individuals. This stage included the highest percentage of patients who died of stroke (n=6; 7%).
– Of the 19 (12%) patients in “overt dysfunction” at diagnosis, HF represented the cause of demise in almost three quarters (n=14, 74%); SCD and non-HCM causes accounted for only 10% and 16% respectively.
Conclusions
Most HCM patients die due to complications of their own disease, mainly in the context of HF. Modes of death vary with the stage of disease, with SCD becoming less prevalent in more advanced phases of progression, when competitive risks of HF-related events become overwhelming. These data highlight an unmet medical need in the prevention of disease progression associated with HCM.

Abstract
Abstract
Background
Excess force generation during myocardial contraction represents a cardinal feature of hypertrophic cardiomyopathy (HCM).
Purpose
To evaluate the anatomical, functional and prognostic correlates of left ventricular (LV) force in HCM.
Methods
We prospectively recruited a consecutive sample of 408 HCM patients with LV ejection fraction (EF) >50%, referred for baseline transthoracic echocardiography in 2 primary HCM centers in Hungary and Italy between 1999 and 2021. LV force was calculated as LV outflow tract gradient+systolic blood pressure/LV end-systolic volume. Patients were followed for a median of 107 months (IQ range, 58–158 months), the study endpoint was all-cause mortality.
Results
Mean LV force was 6.0±4.6 mm Hg/ml. Receiver-operating characteristic analysis identified 7.5 mm Hg/ml the best cut-off value to predict mortality. LV force >7.5 mm Hg/ml was present in 86 patients (21%), more frequently in women (58 vs 27%, p<0.0001), more often in patients with diabetes (16 vs 6%, p=0.003), beta-blocker (81 vs 58%, p<0.0001), calcium channel-blocker (19 vs 9%, p=0.012) and diuretic therapy (19 vs 8%, p=0.004), compared to patients with LV force ≤7.5 mm Hg/ml. Patients with excess LV force had more advanced NYHA class (1.8±0.7 vs 1.4±0.7, p=0.0001), greater left atrial diameter [(LAd), 46.7±6.6 vs 43.0±7.2 mm, <0.0001], LV maximal wall thickness (23.2±5.5 vs 21.6±5.5 mm p=0.01), LV EF (74.6±6.4 vs 67.0±6.8%, <0.0001), mitral regurgitation grade (1.2±0.7 vs 0.7±0.7, p<0.0001) and E/e' (10.3±5.0 vs 7.8±5.0, p=0.005). During follow-up 43 deaths occurred. All-cause death was more frequent in patients with excess LV force (21 vs 8%, p<0.0001). At multivariable Cox regression analysis, excess LV force was an independent predictor of mortality (HR 2.9, 95% CI 1.14–7.26, p=0.025) independent of age (HR 1.03, 95% CI 1.00–1.05, p=0.022) and LAd (HR 1.07, 95% CI 1.02–1.14, p=0.005).
Conclusion
LV force with a threshold of 7.5 mm Hg/ml, independently predicts adverse outcome in patients with HCM and preserved systolic function. Excess LV force generation is associated with female sex, diabetes, NYHA class, medications, LAd, LV wall thickness, EF, mitral regurgitation grade and E/e'.

Abstract
Quiescent cancer cells are rare nondiving cells with the unique ability to evade chemotherapies and resume cell division after treatment. Despite the associated risk of cancer recurrence, how cells can reversibly switch between rapid proliferation and quiescence remains a long‐standing open question. By developing a unique methodology for the cell sorting‐free separation of metabolic profiles in cell subpopulations in vitro, we unraveled metabolic characteristics of quiescent cells that are largely invariant to basal differences in cell types and quiescence‐inducing stimuli. Consistent with our metabolome‐based analysis, we show that impairing mitochondrial fatty acid β‐oxidation (FAO) can induce apoptosis in quiescence‐induced cells and hamper their return to proliferation. Our findings suggest that in addition to mediating energy and redox balance, FAO can play a role in preventing the buildup of toxic intermediates during transitioning to quiescence. Uncovering metabolic strategies to enter, maintain, and exit quiescence can reveal fundamental principles in cell plasticity and new potential therapeutic targets beyond cancer.

Abstract
Cardiac amyloidosis is an infiltrative disease characterized by extracellular deposition of insoluble amyloid fibrils in the heart leading to organ dysfunction. Despite recent diagnostic advances, the diagnosis of cardiac amyloidosis is often delayed or even missed. Furthermore, a long diagnostic delay is associated with adverse outcomes, with the early diagnosed patients showing the longest survival. In this narrative review we aimed to summarize the 'red flags' that may facilitate the correct diagnosis. The red flags may be classified as clinical, biohumoral, electrocardiographic, echocardiographic, and cardiac magnetic resonance features and should promptly raise the suspicion of cardiac amyloidosis in order to start a correct diagnostic pathway and targeted treatment strategies that may improve patients' outcomes.

Abstract
Cardiac amyloidosis (CA) is due to extracellular myocardial deposition of misfolded proteins resulting in severe cardiac dysfunction and death. The precursors of amyloid fibrils, able of determining a relevant cardiac infiltration, are immunoglobulin-free light chains (AL amyloidosis) and transthyretin (TTR) (both wild and mutated types). The diagnosis of amyloidosis represents a challenge for the clinician given its rarity and its protean clinical presentation, thus an early diagnosis remains a cornerstone for the prognosis of these patients, also in light of the growing available treatments. There is great interest in identifying and applying biomarkers to help diagnose, inform prognosis, guide therapy, and serve as surrogate endpoints in these patients. In AL amyloidosis, biomarkers such as free light chains, natriuretic peptides and troponins are the most extensively studied and validated; they have proved useful in risk stratification, guiding treatment choice and monitoring hematological and organ response. A similar biomarker-based prognostic score is also proposed for ATTR amyloidosis, although studies are small and need to be validated for wild-type and mutant forms.

Abstract
BACKGROUND The valine-to-isoleucine substitution (Val122Ile) is the most common variant of transthyretin (TTR) amyloidosis in the United States, affecting primarily individuals of African descent. This variant has been identified recently in a cluster of white individuals in Italy. METHODS AND RESULTS Clinical phenotype and chamber performance of Black and white individuals with Val122Ile TTR cardiac amyloidosis (ATTR-CA) were compared. Compared to white patients (n = 17), Black individuals (n = 53) had lower systolic blood pressures (110 vs 131 mmHg, <0.001), reduced pulse pressures (41 vs 58 mmHg; P < 0.001), and impaired renal function (eGFR 46 vs 67 mL/min/1.73m2; P < 0.001) at presentation. Systolic properties and arterial elastance were similar. Black patients had end-diastolic pressure-volume relationships that were shifted upward and leftward relative to those of white patients, indicating reduced left ventricular chamber capacitance. Pressure-volume area at a left ventricular end-diastolic pressure of 30 mmHg was lower in Black than in white individuals (8055 mmHg/mL vs 11,538 mmHg/mL; P = 0.008). CONCLUSION Despite presenting at ages similar to those of white patients, Black individuals with Val122Ile-associated ATTR-CA had a greater degree of cardiac chamber dysfunction at the time of diagnosis due to impaired ventricular capacitance. Whether these differences are attributable to amyloidosis or other cardiovascular disease requires further study.

Abstract
AIMS The incidence and risk factors of pacemaker (PM) implantation in patients with cardiac amyloidosis (CA) are largely unexplored. We sought to characterise the trends in the incidence of permanent PM and to identify baseline predictors of future PM implantation in light chain (AL) and transthyretin (ATTR) CA. METHODS AND RESULTS Consecutive patients with AL and ATTR-CA diagnosed at participating Centres (2017-2020) were included. Clinical data recorded within ±1 month from diagnosis were collected from electronic medical records. The primary study outcome was the need for clinically-indicated PM implantation. Patients with PM (n = 41) and/or permanent defibrillator in situ (n = 13) at CA diagnosis were excluded. The study population consisted of 405 patients: 29.4% AL, 14.6% variant ATTR and 56% wild-type ATTR; 82.5% were males, median age 76 years. During a median follow-up of 33 months (interquartile range 21-46), 36 (8.9%) patients experienced the primary outcome: 10 AL-CA, 2 variant ATTR-CA and 24 wild-type ATTR-CA (p = 0.08 at time-to-event analysis). At multivariable analysis, history of atrial fibrillation (hazard ratio [HR] 3.80, p = 0.002), PR interval (HR 1.013, p = 0.002) and QRS >120 ms (HR 4.7, p = 0.001) on baseline ECG were independently associated with PM implantation. The absence of these 3 factors had a negative predictive value of 92% with an area under the curve of 91.8% at 6 months. CONCLUSION In a large cohort of AL and ATTR-CA patients, 8.9% implanted a PM in the 3 years following diagnosis. History of atrial fibrillation, PR >200 ms and QRS >120 ms predicted future PM implantation.
