RESUMEN
BACKGROUND: A new definition of metabolically healthy obesity (MHO) has recently been proposed to stratify the heterogeneous mortality risk of obesity. Metabolomic profiling provides clues to metabolic alterations beyond clinical definition. We aimed to evaluate the association between MHO and cardiovascular events and assess its metabolomic pattern. METHODS: This prospective study included Europeans from two population-based studies, the FLEMENGHO and the Hortega study. A total of 2339 participants with follow-up were analyzed, including 2218 with metabolomic profiling. Metabolic health was developed from the third National Health and Nutrition Examination Survey and the UK biobank cohorts and defined as systolic blood pressure < 130 mmHg, no antihypertensive drugs, waist-to-hip ratio < 0.95 for women or 1.03 for men, and the absence of diabetes. BMI categories included normal weight, overweight, and obesity (BMI < 25, 25-30, ≥ 30 kg/m2). Participants were classified into six subgroups according to BMI category and metabolic healthy status. Outcomes were fatal and nonfatal composited cardiovascular events. RESULTS: Of 2339 participants, the mean age was 51 years, 1161 (49.6%) were women, 434 (18.6%) had obesity, 117 (5.0%) were classified as MHO, and both cohorts had similar characteristics. Over a median of 9.2-year (3.7-13.0) follow-up, 245 cardiovascular events occurred. Compared to those with metabolically healthy normal weight, individuals with metabolic unhealthy status had a higher risk of cardiovascular events, regardless of BMI category (adjusted HR: 3.30 [95% CI: 1.73-6.28] for normal weight, 2.50 [95% CI: 1.34-4.66] for overweight, and 3.42 [95% CI: 1.81-6.44] for obesity), whereas those with MHO were not at increased risk of cardiovascular events (HR: 1.11 [95% CI: 0.36-3.45]). Factor analysis identified a metabolomic factor mainly associated with glucose regulation, which was associated with cardiovascular events (HR: 1.22 [95% CI: 1.10-1.36]). Individuals with MHO tended to present a higher metabolomic factor score than those with metabolically healthy normal weight (0.175 vs. -0.057, P = 0.019), and the score was comparable to metabolically unhealthy obesity (0.175 vs. -0.080, P = 0.91). CONCLUSIONS: Individuals with MHO may not present higher short-term cardiovascular risk but tend to have a metabolomic pattern associated with higher cardiovascular risk, emphasizing a need for early intervention.

Drug-drug interactions (DDIs) are common in cancer management and complicate the choice of anticoagulation in cancer-associated thrombosis. Cancer confers an increased risk of thrombotic events. Also, more bleeding events are observed in those who receive anticoagulation compared to those without cancer. In the treatment of cancer-associated thrombosis, direct oral anticoagulants (DOACs) have been found to be at least as effective as low-molecular weight heparins, which became the standard of care after several trials demonstrated superiority over vitamin K antagonists. Non-inferiority compared to low-molecular weight heparins has been shown for rivaroxaban, edoxaban and apixaban with a signal of fewer recurrent thrombotic events, albeit with an increase in bleeding events. Yet, potentially major pharmacokinetic drug-drug interactions have been identified as a reason to withhold DOACs and to rather choose an alternative. Practical guidance on what constitutes a major pharmacokinetic interaction and/or how to deal with these interactions in clinical practice is limited. Hence, here we have provided a framework to allow clinicians to better deal with pharmacokinetic drug-drug interactions between DOACs and cancer therapies in the management of cancer-associated thrombosis. In this review we have discussed the current literature, how the pharmacokinetic profile links to the label information on DDI, and have provided a practical proposal, applied to a clinical case.

INTRODUCTION: Cytomegalovirus (CMV) is the most clinically relevant infectious agent following heart transplantation (HTX). Data on the beneficial effects of prophylactic use of CMV immunoglobulins (CMVIG) are scarce. METHODS: In this single-center, retrospective study, we reported patient outcomes following cardiac transplantation using prophylactic CMV treatment, including CMVIG. Distinct clinically relevant outcomes were compared across different CMV risk groups (CMV D-/R-, CMV D-/R+, CMV D+/R+, and CMV D+/R- or CMV high risk group). RESULTS: We included 272 heart transplant procedures, performed between 1/1/2009 and 1/11/2020. Sixty-one (22%) procedures belonged to the CMV high risk group, while 96 (35%), 50 (18%), and 65 (24%) were CMV D-/R-, CMV D-/R+, and CMV D+/R+, respectively. Baseline donor and recipient characteristics (sex, age, body mass index, cause of death, indication for HTX), ischemia times and baseline immunosuppressive regimens were similar across the different CMV risk groups, yet fewer patients were bridged with a mechanical circulatory support in the CMV D+/R- group. CMV disease following cardiac transplantation was more common in the CMV D+/R- risk group (n = 40 or 66.7%; p < .001), yet mortality and re-transplantation rates, cardiac allograft vasculopathy (CAV) severity, rejection episodes, and development of donor-specific antibodies (DSA), post-transplant lymphoproliferative diseases (PTLD), and EBV infections were similar across all four CMV risk groups. CONCLUSION: High risk CMV D+/R- patients had a similar survival compared to low and intermediate CMV risk groups using a prophylactic strategy combining CMVIG and viral DNA polymerase inhibitors. This may be related to a number of factors unrelated to prophylaxis strategy as two out of three CMV D+/R- recipients developed CMV primary infection after prophylaxis was discontinued.

Maximal exercise capacity of patients after heart transplantation (HTX) remains limited, affecting their quality of life. Evidence on the evolution of muscle strength and physical activity (PA) post-HTX is lacking, but a prerequisite to tailor cardiac rehabilitation programmes. Forty-five consecutive patients were evaluated every 3 months during the first year post-HTX. Functional exercise capacity (Six minutes walking distance test (6MWD)), peripheral (Quadriceps strength (QF)) and respiratory (Maximal inspiratory strength (MIP)) muscle strength were evaluated. PA (number of steps (PAsteps), active time (PAactive) and sedentary time (PAsed)) was objectively measured. 6MWD, QF, MIP, PAsteps and PAactive significantly improved over time (P < 0.001). No change in PAsed was noticed (P = 0.129). Despite improvements in 6MWD and QF, results remained substantially below those of age-and gender-matched healthy subjects. One year post-HTX, 30% of patients presented with peripheral muscle weakness. Baseline levels of 6MWD and QF were significantly higher in patients with pretransplant LVAD-implantation and this difference was maintained during follow-up. cardiac rehabilitation, combining aerobic exercise training and peripheral muscle strength training, is mandatory in patients post-HTX. Inspiratory muscle training should be implemented when respiratory muscle weakness is present. Programmes improving physical activity and reducing sedentary time post-HTX are essential.

BACKGROUND: Chronic kidney disease (CKD) is common in patients after heart transplantation (HTx). We assessed whether in HTx recipients the proteomic urinary classifier CKD273 or sequenced urinary peptides revealing the parental proteins correlated with the estimated glomerular filtration rate (eGFR). METHODS: In 368 HTx patients, we measured the urinary peptidome and analysed CKD273 and 48 urinary peptides with a detectable signal in >95% of participants. After 9.1 months (median), eGFR and the urinary biomarkers were reassessed. RESULTS: In multivariable Bonferroni-corrected analyses of the baseline data, a 1-SD increase in CKD273 was associated with a 11.4 [95% confidence interval (CI) 7.25-15.5] mL/min/1.73 m2 lower eGFR and an odds ratio of 2.63 (1.56-4.46) for having eGFR <60 mL/min/1.73 m2. While relating eGFR category at follow-up to baseline urinary biomarkers, CKD273 had higher (P = 0.007) area under the curve (0.75; 95% CI 0.70-0.80) than 24-h proteinuria (0.64; 95% CI 0.58-0.69), but additional adjustment for baseline eGFR removed significance of both biomarkers. In partial least squares analysis, the strongest correlates of the multivariable-adjusted baseline eGFR were fragments of collagen I (positive) and the mucin-1 subunit α (inverse). Associations between the changes in eGFR and the urinary markers were inverse for CKD273 and mucin-1 and positive for urinary collagen I. CONCLUSIONS: With the exception of baseline eGFR, CKD273 was more closer associated with imminent renal dysfunction than 24-h proteinuria. Fragments of collagen I and mucin-1-respectively, positively and inversely associated with eGFR and change in eGFR-are single-peptide markers associated with renal dysfunction.

BACKGROUND: Data are scarce on the prognosis of heart allograft antibody-mediated rejection (AMR) with cardiogenic shock (CS). METHODS: We performed a retrospective, single center, observational study. We included patients with biopsy-proven AMR and CS. We aimed to analyze the characteristics, treatment, and prognosis of patients treated for CS due to AMR. Patients alive after AMR were followed to analyze recurrences of AMR, graft function, and cardiac allograft vasculopathy (CAV). RESULTS: Seventeen patients met the inclusion criteria. Patients were mostly males (70%). Median age at diagnosis was 56 years, and median time between heart transplantation and AMR was 21 months. AMR was mostly due to high-level de novo class II DSA. Only 2 patients had past history of biopsy-proven AMR. Despite aggressive immunosuppressive therapies, in-hospital and 1-year mortality were as high as 76% and 82%, respectively. Four patients were discharged from hospital. Two of them were diagnosed with recurrent subclinical AMR: one died suddenly and the other presented rapidly progressive CAV. CONCLUSION: CS due to AMR occurred mostly in patients without history of AMR who developed de novo class II DSA. Despite aggressive conventional immunosuppressive therapies, prognosis after CS due to AMR was poor.

RATIONALE: To maintain cardiac mechanical and structural integrity after an ischemic insult, profound alterations occur within the extracellular matrix. Osteoglycin is a small leucine-rich proteoglycan previously described as a marker of cardiac hypertrophy. OBJECTIVE: To establish whether osteoglycin may play a role in cardiac integrity and function after myocardial infarction (MI). METHODS AND RESULTS: Osteoglycin expression is associated with collagen deposition and scar formation in mouse and human MI. Absence of osteoglycin in mice resulted in significantly increased rupture-related mortality with tissue disruption, intramyocardial bleeding, and increased cardiac dysfunction, despite equal infarct sizes. Surviving osteoglycin null mice had greater infarct expansion in comparison with wild-type mice because of impaired collagen fibrillogenesis and maturation in the infarcts as revealed by electron microscopy and collagen polarization. Absence of osteoglycin did not affect cardiomyocyte hypertrophy in the remodeling remote myocardium. In cultured fibroblasts, osteoglycin knockdown or supplementation did not alter transforming growth factor-ß signaling. Adenoviral overexpression of osteoglycin in wild-type mice significantly improved collagen quality, thereby blunting cardiac dilatation and dysfunction after MI. In osteoglycin null mice, adenoviral overexpression of osteoglycin was unable to prevent rupture-related mortality because of insufficiently restoring osteoglycin protein levels in the heart. Finally, circulating osteoglycin levels in patients with heart failure were significantly increased in the patients with a previous history of MI compared with those with nonischemic heart failure and correlated with survival, left ventricular volumes, and other markers of fibrosis. CONCLUSIONS: Increased osteoglycin expression in the infarct scar promotes proper collagen maturation and protects against cardiac disruption and adverse remodeling after MI. In human heart failure, osteoglycin is a promising biomarker for ischemic heart failure.

PURPOSE OF REVIEW: Heart failure (HF) is a common, costly, disabling, and deadly clinical syndrome and often associated with one or several co-morbidities complicating its treatment or worsening its symptoms. During the last decade, iron deficiency (ID) got recognized as a frequent, debilitating yet easily treatable co-morbidity in HF. In this review, we focus on new evidence that emerged during the last 5 years and discuss the epidemiology, the causes, and the clinical consequences of ID in HF. RECENT FINDINGS: Apart from replenishing iron stores, intravenous iron improves patients' symptoms, perceived quality of life (QoL), exercise capacity, and hospitalization rates. These beneficial effects cannot be attributed to oral iron, as increased hepcidin levels, typical in inflammatory states such as HF, preclude resorption of iron from the gut. Intravenous iron is the only valid treatment option for ID in HF. However, there are several burning research questions and gaps in evidence remaining in this research field.

AIMS: The cardiac extracellular matrix is highly involved in regulating inflammation, remodelling, and function of the heart. Whether matrix alterations relate to the degree of inflammation, fibrosis, and overall rejection in the human transplanted heart remained, until now, unknown. METHODS AND RESULTS: Expression of matricellular proteins, proteoglycans, and metalloproteinases (MMPs) and their inhibitors (TIMPs) were investigated in serial endomyocardial biopsies (n = 102), in a cohort of 39 patients within the first year after cardiac transplantation. Out of 15 matrix-related proteins, intragraft transcript and protein levels of syndecan-1 and MMP-9 showed a strong association with the degree of cardiac allograft rejection (CAR), the expression of pro-inflammatory cytokines tumour necrosis factor (TNF)-α, interleukin (IL)-6 and transforming growth factor (TGF)-ß, and with infiltrating CD3⺠T-cells and CD68⺠monocytes. In addition, SPARC, CTGF, TSP-2, MMP-14, TIMP-1, Testican-1, TSP-1, Syndecan-1, MMP-2, -9, and -14, as well as IL-6 and TGF-ß transcript levels and inflammatory infiltrates all strongly relate to collagen expression in the transplanted heart. More importantly, receiver operating characteristic curve analysis demonstrated that syndecan-1 and MMP-9 transcript levels had the highest area under the curve (0.969 and 0.981, respectively), thereby identifying both as a potential decision-making tool to discriminate rejecting from non-rejecting hearts. CONCLUSION: Out of 15 matrix-related proteins, we identified synd-1 and MMP-9 intragraft transcript levels of as strong predictors of human CAR. In addition, a multitude of non-structural matrix-related proteins closely associate with collagen expression in the transplanted heart. Therefore, we are convinced that these findings deserve further investigation and are likely to be of clinical value to prevent human CAR.

Staphylococcus aureus (S. aureus) is a frequent cause of catheter-related infections. S. aureus secretes the coagulases staphylocoagulase and von Willebrand factor-binding protein, both of which form a staphylothrombin complex upon binding to prothrombin. Although fibrinogen and fibrin facilitate the adhesion of S. aureus to catheters, the contribution of staphylothrombin-mediated fibrin has not been examined. In this study, we use a S. aureus mutant lacking both coagulases (Δcoa/vwb) and dabigatran, a pharmacological inhibitor of both staphylothrombin and thrombin, to address this question. Genetic absence or chemical inhibition of pathogen-driven coagulation reduced both fibrin deposition and the retention of S. aureus on catheters in vitro. In a mouse model of jugular vein catheter infection, dabigatran reduced bacterial load on jugular vein catheters, as well as metastatic kidney infection. Importantly, inhibition of staphylothrombin improved the efficacy of vancomycin treatment both in vitro and in the mouse model.

INTRODUCTION: The pharmacy profession faces a lack of evidence pertaining to pharmaceutical care in oncology, both in terms of its effectiveness and its integration into clinical practice. While Europe-based pharmacists are active in many therapeutic areas, their role in cancer care is less defined. Conversely, the complexity of oncology, increasing cancer cases, and evolving therapies highlight the potential for pharmacists in this field. Their limited involvement in Europe may be attributed to inadequate undergraduate training and research. PERSPECTIVE: Collaborative care shows potential in oncology, but still needs more trial evidence. Here, we can learn from pharmaceutical care in cardiology, where more research has been conducted. The limited role of pharmacists in oncology may be due to a lack of focus on oncology research and insufficient education. IMPLICATIONS: Addressing the teaching gap requires improving oncology education in pharmacy programs, at both undergraduate and postgraduate levels. Current postgraduate courses and US PharmD programs could serve as models. Equipping pharmacy students with fundamental oncology knowledge is a vital first step, for further meaningful research and practice. Formal education could bridge the gap between evidence and practice in these fields.

Background: Transthyretin (ATTR) amyloidosis is more prevalent than initially thought. As much as 13% of patients hospitalized with heart failure with preserved ejection fraction may have ATTR-cardiomyopathy (CM). Conversely, heart transplant patients may manifest left ventricular hypertrophy or diastolic dysfunction, especially late after transplantation. Case summary: We present a case of a 82-year-old male heart transplant patient, 31 years following orthotopic heart transplantation. While he was satisfied with his exercise capacity as an octogenarian, several years before, he required pacemaker implantation due to third-degree atrioventricular block, had bilateral carpal tunnel syndrome treated with carpal tunnel release surgery, and experienced idiopathic sudden deafness. Based on increasing left ventricular wall thickness during routine follow-up, a diagnosis of ATTR amyloidosis was suspected. Ultimately, the diagnosis was confirmed non-invasively with a specific scintigraphic exam, while an additional physicochemical stain on an endomyocardial biopsy taken several years before provided pathological proof. We initiated tafamidis, yet stopped this treatment after 1 month because of gastrointestinal intolerance. Ultimately, our patient died 2 years later due to heart failure. Discussion: Our case shows the long delay between the onset of ATTR deposition, the presence of clinical signs, and the final diagnosis. Echocardiographic findings suggestive for ATTR-CM include left ventricular hypertrophy and diastolic dysfunction, which are both common in heart transplant patients. Yet, ATTR-CM should be considered in the differential diagnosis, especially late after transplantation, in this closely monitored population.
RESUMEN
BACKGROUND: Atrial fibrillation occurs in nearly half of geriatric inpatients and is a major cause of morbidity and mortality. Suboptimal anticoagulation use is an important concern in this population. This study aimed to evaluate the appropriateness of antithrombotic therapies in this patient cohort. METHODS: A retrospective analysis was conducted on the geriatric wards of a teaching hospital in Belgium, on a background of clinical pharmacy services. The first 90 atrial fibrillation patients from 2020 to 2022 were included if they received an oral anticoagulant. We assessed utilisation and appropriateness of antithrombotics at discharge, examined reasons for guideline deviations, and explored factors associated with underdosing. Temporal associations for appropriateness and type of anticoagulant (vitamin K antagonist (VKA) vs direct oral anticoagulant (DOAC)) were assessed. RESULTS: The mean age of patients was 86.5 (±5.3) years and the median CHA2DS2-VASc score was 5 (interquartile range (IQR) 4-6). At discharge, 256 (94.8%) patients used a DOAC; nine (3.3%) used a VKA; one (0.4%) a DOAC-antiplatelet combination, and in four patients (1.5%) all antithrombotics were discontinued. The majority (64.4%) of patients received reduced DOAC doses with apixaban prescribed in 40.7%. In 39 (14.4%) patients, antithrombotic use was considered inappropriate, mostly without a rationale (23/39). Year 2022 (odds ratio (OR) 0.104; 95% confidence interval (CI), 0.012-0.878) was the sole determinant for underdosing. No significant differences were found with respect to appropriateness (p=0.533) or anticoagulant class (p=0.479) over time. CONCLUSION: Most geriatric inpatients received a justified reduced DOAC dose. A significant proportion was managed inappropriately with underdosing (= unjustified reduced dose) being most common. Frequently no rationale was provided for deviating from trial-tested doses.
RESUMEN
AIMS: Cardiotoxicity is a serious side effect of anthracycline treatment, most commonly manifesting as a reduction in left ventricular ejection fraction (EF). Early recognition and treatment have been advocated, but robust, convenient, and cost-effective alternatives to cardiac imaging are missing. Recent developments in artificial intelligence (AI) techniques applied to electrocardiograms (ECGs) may fill this gap, but no study so far has demonstrated its merit for the detection of an abnormal EF after anthracycline therapy. METHODS AND RESULTS: Single centre consecutive cohort study of all breast cancer patients with ECG and transthoracic echocardiography (TTE) evaluation before and after (neo)adjuvant anthracycline chemotherapy. Patients with HER2-directed therapy, metastatic disease, second primary malignancy, or pre-existing cardiovascular disease were excluded from the analyses as were patients with EF decline for reasons other than anthracycline-induced cardiotoxicity. Primary readout was the diagnostic performance of AI-ECG by area under the curve (AUC) for EFs < 50%. Of 989 consecutive female breast cancer patients, 22 developed a decline in EF attributed to anthracycline therapy over a follow-up time of 9.8 ± 4.2 years. After exclusion of patients who did not have ECGs within 90 days of a TTE, 20 cases and 683 controls remained. The AI-ECG model detected an EF < 50% and ≤ 35% after anthracycline therapy with an AUC of 0.93 and 0.94, respectively. CONCLUSION: These data support the use of AI-ECG for cardiotoxicity screening after anthracycline-based chemotherapy. This technology could serve as a gatekeeper to more costly cardiac imaging and could enable patients to monitor themselves over long periods of time.
Artificial intelligence electrocardiogram can be used to screen for an abnormal heart function after anthracycline chemotherapy, opening the door to new ways of cost-effective screening of cancer survivors at risk of cardiotoxicity over long periods of time.

Heart failure (HF) occurs predominantly in older adults. HF patients have an increased risk for an acute exacerbation, which commonly requires hospitalisation. Such a worsening HF (WHF) event has an impact on prognosis. Vericiguat is a novel agent which has been shown to reduce the HF hospitalisation risk in patients with a recent WHF event. It is not fully clear how to position this novel agent in geriatric HF inpatients.

Heart failure is a prevalent syndrome among older adults, with a major impact on morbidity and mortality. Higher age is correlated with underuse of guideline-directed medical therapies which, in turn, has been linked to worse clinical outcomes. Importantly, most evidence so far has been collected in adults who were younger, less multi-morbid and polymedicated compared with those who are commonly treated in daily clinical practice. Hence, we aimed to assess and describe the evidence base for pharmacotherapy in older adults with heart failure with a reduced ejection. First, a narrative review was undertaken using Medline, from inception to January 2023. Four foundational therapies were selected based on the latest European Society of Cardiology clinical practice guideline: angiotensin-converting enzyme inhibitors/angiotensin receptor neprilysin inhibitors, beta blockers, mineralocorticoid receptor antagonists and sodium-glucose cotransporter-2 inhibitors. Post hoc analyses from landmark heart failure drug trials were searched and included if they contained data on the impact of age on efficacy, safety and/or timeliness of therapies in the management of heart failure with a reduced ejection fraction. Second, a proposal was developed to support and promote the use of evidence-based heart failure pharmacotherapy in complex, older adults. In total, 11 articles were selected: 4 meta-analyses, 6 post hoc analyses and 1 review paper. No attenuation of efficacy for any of the foundational agents was found in older adults. Regarding safety, dedicated analyses showed that beta blockers, mineraloid receptor antagonists, sacubitril-valsartan, dapagliflozin and empagliflozin retained their overall benefit-risk profile regardless of age. Time to benefit was short and occurred generally within 1 month. Consensus was achieved on a five-step proposal to manage complex medication regimens in older adults suffering from heart failure. In conclusion, older adults suffering from heart failure with a reduced ejection fraction should not be denied treatment based on their age.

AIMS: Coronary artery disease (CAD) is multifactorial, caused by complex pathophysiology, and contributes to a high burden of mortality worldwide. Urinary proteomic analyses may help to identify predictive biomarkers and provide insights into the pathogenesis of CAD. METHODS AND RESULTS: Urinary proteome was analysed in 965 participants using capillary electrophoresis coupled with mass spectrometry. A proteomic classifier was developed in a discovery cohort with 36 individuals with CAD and 36 matched controls using the support vector machine. The classifier was tested in a validation cohort with 115 individuals who progressed to CAD and 778 controls and compared with two previously developed CAD-associated classifiers, CAD238 and ACSP75. The Framingham and SCORE2 risk scores were available in 737 participants. Bioinformatic analysis was performed based on the CAD-associated peptides. The novel proteomic classifier was comprised of 160 urinary peptides, mainly related to collagen turnover, lipid metabolism, and inflammation. In the validation cohort, the classifier provided an area under the receiver operating characteristic curve (AUC) of 0.82 [95% confidence interval (CI): 0.78-0.87] for the CAD prediction in 8 years, superior to CAD238 (AUC: 0.71, 95% CI: 0.66-0.77) and ACSP75 (AUC: 0.53 and 95% CI: 0.47-0.60). On top of CAD238 and ACSP75, the addition of the novel classifier improved the AUC to 0.84 (95% CI: 0.80-0.89). In a multivariable Cox model, a 1-SD increment in the novel classifier was associated with a higher risk of CAD (HR: 1.54, 95% CI: 1.26-1.89, P < 0.0001). The new classifier further improved the risk reclassification of CAD on top of the Framingham or SCORE2 risk scores (net reclassification index: 0.61, 95% CI: 0.25-0.95, P = 0.001; 0.64, 95% CI: 0.28-0.98, P = 0.001, correspondingly). CONCLUSION: A novel urinary proteomic classifier related to collagen metabolism, lipids, and inflammation showed potential for the risk prediction of CAD. Urinary proteome provides an alternative approach to personalized prevention.
A biomarker that can predict coronary artery disease (CAD) is urgently in need. We developed and validated a urinary proteomic classifier for the prediction of CAD. The proteomic classifier involved in atherosclerosis improved the risk reclassification on top of the clinical risk score.

Whereas truncating variants of the giant protein Titin (TTNtv) are the main cause of familial dilated cardiomyopathy (DCM), recently Filamin C truncating variants (FLNCtv) were identified as a cause of arrhythmogenic cardiomyopathy (ACM). Our aim was to characterize and compare clinical and MRI features of TTNtv and FLNCtv in the Belgian population. In index patients referred for genetic testing of ACM/DCM, FLNCtv and TTNtv were found in 17 (3.6%) and 33 (12.3%) subjects, respectively. Further family cascade screening yielded 24 and 19 additional truncating variant carriers in FLNC and TTN, respectively. The main phenotype was ACM in FLNCtv carriers whereas TTNtv carriers showed either an ACM or DCM phenotype. Non-sustained Ventricular Tachycardia was frequent in both populations. MRI data, available in 28/40 FLNCtv and 32/52 TTNtv patients, showed lower Left Ventricular (LV) ejection fraction and lower LV strain in TTNtv patients (p < 0.01). Conversely, both the frequency (68% vs 22%) and extent of non-ischemic myocardial late gadolinium enhancement (LGE) was significantly higher in FLNCtv patients (p < 0.01). Hereby, ring-like LGE was found in 16/19 (84%) FLNCtv versus 1/7 (14%) of TTNtv patients (p < 0.01). In conclusion, a large number of FLNCtv and TTNtv patients present with an ACM phenotype but can be separated by cardiac MRI. Whereas FLNCtv patients often have extensive myocardial fibrosis, typically following a ring-like pattern, LV dysfunction without or limited replacement fibrosis is the common TTNtv phenotype.

Background Treatment for breast cancer (BC) frequently involves radiotherapy. Guidelines recommend screening for cardiac adverse events starting 10 years after radiotherapy. The rationale for this interval is unclear. Methods and Results We aimed to study cardiovascular event rates in the first decade following curative radiotherapy for BC. We compared mortality and cardiovascular event rates with an age- and risk factor-matched control population. We included 1095 patients with BC (mean age 56±12 years). Two hundred and eighteen (19.9%) women died. Cancer and cardiovascular mortality caused 107 (49.1%) and 22 (10.1%) deaths, respectively. A total of 904 cases were matched to female FLEMENGHO (Flemish Study on Environment, Genes and Health Outcomes) participants. Coronary artery disease incidence was similar (risk ratio [RR], 0.75 [95% CI, 0.48-1.18]), yet heart failure (RR, 1.97 [95% CI, 1.19-3.25]) and atrial fibrillation/flutter (RR, 1.82 [95% CI, 1.07-3.08]) occurred more often in patients with BC. Age (hazard ratio [HR], 1.033 [95% CI, 1.006-1.061], P=0.016), tumor grade (HR, 1.739 [95% CI, 1.166-2.591], P=0.007), and neoadjuvant treatment setting (HR, 2.782 [95% CI, 1.304-5.936], P=0.008) were risk factors for mortality. Risk factors for major adverse cardiac events were age (HR, 1.053 [95% CI, 1.013-1.093]; P=0.008), mean heart dose (HR, 1.093 [95% CI, 1.025-1.167]; P=0.007), history of cardiovascular disease (HR, 2.386 [95% CI, 1.096-6.197]; P=0.029) and Mayo Clinic Cardiotoxicity Risk Score (HR, 2.664 [95% CI, 1.625-4.367]; P<0.001). Conclusions Ten-year mortality following curative treatment for unilateral BC was mainly cancer related, but heart failure and atrial fibrillation/flutter were already common in the first decade following irradiation. Mean heart dose, pre-existing cardiovascular diseases, and Mayo Clinic Cardiotoxicity Risk Score were risk factors for cardiac adverse events. These results suggest a need for early dedicated cardio-oncological follow-up after radiotherapy.
