Background:No study has evaluated the clinical consequences of stent fracture (SF) detected during the index percutaneous coronary intervention (PCI). Thus, we sought to investigate the relationship ...between SF detected during PCI and clinical outcome.Methods and Results:We consecutively enrolled 832 patients with SF-predisposing factors undergoing 2nd-generation drug-eluting stent implantation and enhanced stent visualization (ESV) system evaluation to detect SF at index PCI. The primary endpoint was a 9-month device-oriented endpoint (DOCE, including cardiac death, target vessel myocardial infarction, and target lesion revascularization). We observed 136 SF in 115 patients (14% of study population). SF I–II was present in 78 patients (68% of patients with SF), and SF III–IV occurred in 37 patients (32%). DOCE at 9 months occurred in 135 patients (16% of the overall population). There was a significant difference in DOCE occurrence between the 3 groups (P=0.006 at log-rank), driven by the SF III–IV group (P=0.001 vs. no SF group, and P=0.01 vs. SF I–II group). In 23 cases of SF III–IV (62%) a further stent was implanted. DOCE occurrence was significantly higher in patients with “untreated” type III–IV SF as compared with the “treated” ones (9% vs. 79%, P<0.01).Conclusions:The ESV system is helpful in detecting SF during the index PCI. Type III–IV SFs are associated with a higher incidence of DOCE.
Background The 12-lead ECG plays a key role in the diagnosis of Brugada syndrome (BrS). Since the spontaneous type 1 ECG pattern was first described, several other ECG signs have been linked to ...arrhythmic risk, but results are conflicting. Methods and Results We performed a systematic review to clarify the associations of these specific ECG signs with the risk of syncope, sudden death, or equivalents in patients with BrS. The literature search identified 29 eligible articles comprising overall 5731 patients. The ECG findings associated with an incremental risk of syncope, sudden death, or equivalents (hazard ratio ranging from 1.1-39) were the following: localization of type 1 Brugada pattern (in V2 and peripheral leads), first-degree atrioventricular block, atrial fibrillation, fragmented QRS, QRS duration >120 ms, R wave in lead aVR, S wave in L1 (≥40 ms, amplitude ≥0.1 mV, area ≥1 mm
), early repolarization pattern in inferolateral leads, ST-segment depression, T-wave alternans, dispersion of repolarization, and Tzou criteria. Conclusions At least 12 features of standard ECG are associated with a higher risk of sudden death in BrS. A multiparametric risk assessment approach based on ECG parameters associated with clinical and genetic findings could help improve current risk stratification scores of patients with BrS and warrants further investigation.

Background
Amyloid transthyretin (ATTR) amyloidosis is caused by the systemic deposition of transthyretin molecules, either normal (wild‐type ATTR, ATTRwt) or mutated (variant ATTR, ATTRv). ATTR ...amyloidosis is a disease with a severe impact on patients’ quality of life (QoL). Nonetheless, limited attention has been paid to QoL so far, and no specific tools for QoL assessment in ATTR amyloidosis currently exist. QoL can be evaluated through patient‐reported outcome measures (PROMs), which are completed by patients, or through scales, which are compiled by clinicians. The scales investigate QoL either directly or indirectly, i.e., by assessing the degree of functional impairment and limitations imposed by the disease.
Design
Search for the measures of QoL evaluated in phase 2 and phase 3 clinical trials on ATTR amyloidosis.
Results
Clinical trials on ATTR amyloidosis have used measures of general health status, such as the Short Form 36 Health Survey (SF‐36), or tools developed in other disease settings such as the Kansas City Cardiomyopathy Questionnaire (KCCQ) or adaptations of other scales such as the modified Neuropathy Impairment Score +7 (mNIS+7).
Conclusions
Scales or PROMs for ATTR amyloidosis would be useful to better characterize newly diagnosed patients and to assess disease progression and response to treatment. The ongoing ITALY (Impact of Transthyretin Amyloidosis on Life qualitY) study aims to develop and validate 2 PROMs encompassing the whole phenotypic spectrum of ATTRwt and ATTRv amyloidosis, that might be helpful for patient management and may serve as surrogate endpoints for clinical trials.
Background
Frailty has become a high-priority issue in cardiovascular medicine because of the aging of cardiovascular patients. Simple and reproducible tools to assess frailty in elderly patients are ...clearly on demand. Their application may help physicians in the selection of invasive and medical treatments and in the timing and modality of the follow-up. The frailty in elderly patients receiving cardiac interventional procedures (FRASER) program is designed with the aim to validate the use of the short physical performance battery (SPPB) as prognostic tools in patients admitted to hospital for acute coronary syndrome (ACS).
Methods
The FRASER program is a multicenter prospective study involving 4 Italian cardiology units. The FRASER program enrolls only patients aged ≥70 years. The core of the FRASER program includes patients admitted to hospital for ACS. The aims are (1) to describe SPPB distribution before hospital discharge and (2) to investigate the prognostic role of SPPB score. The primary outcome is a composite of 1-year all-cause mortality and hospital readmission for any cause. Ancillary analyses will be focused on different study populations (patients hospitalized for arrhythmias or acute heart failure or symptomatic severe aortic stenosis) and on different tools to assess frailty (multidimensional prognostic index, clinical frailty score, grip strength).
Discussion
The FRASER program will fill critical gaps in the knowledge regarding the link between frailty, cardiovascular disease, interventional procedures and outcome and will help physicians in the generation of a more personalized risk assessment and in the identification of potential targets for interventions.
Sex influences outcome of patients with acute coronary syndrome (ACS). If there is a relationship between sex and physical performance is unknown.
The analysis is based on older (≥70 years) ACS ...patients included in the FRASER, HULK, and LONGEVO SCA prospective studies. Physical performance was assessed by Short Physical Performance Battery (SPPB). The primary outcome was all-cause mortality.
The study included 1388 patients, and 441 (32%) were women. At presentation, women were older and more compromised than men. After a median follow-up of 998 730-1168 days, all-cause death occurred in 334 (24.1%) patients. At univariate analysis, female sex was related to increased risk of death. After adjustments for confounding factors, female sex was no longer associated with mortality. Women showed poor physical performance compared with men (p < 0.001). SPPB values emerged as an independent predictor of death. Including clinical features and SPPB in the multivariable model, we observed a paradigm shift in the prognostic role of female sex that becomes a protective factor (HR 0.73, 95% CI 0.56-0.96). Sex and physical performance showed a significant interaction (p = 0.03). For lower SPPB values (poor physical performance), sex-related changes in mortality were not recorded, while in patients with higher SPPB values (preserved physical performance), female sex was associated with better survival.
Two key findings emerged from the present real-life cohort of older ACS patients: (i) physical performance strongly influences long-term mortality; (ii) women with preserved physical performance have a better outcome compared to men.

Nuisance bleeding is a major determinant of quality of life and drug discontinuation in patients on dual antiplatelet therapy (DAPT). However, no randomized trial has been focused on the impact of ...nuisance bleeding on quality of life.
BATMAN is an investigator-driven, randomized, controlled, single-center, open trial (NCT02554006). Four hundred and forty-eight consecutive patients with indication to at least 6 months of DAPT were randomized to: i) multimodal counseling program focused on nuisance bleedings (interventional arm); ii) usual discharge process (control arm). The primary endpoint was the one-month health-related quality of life assessed by the EuroQol-5 Dimension (EQ-5D) visual analog scale (VAS) score. Secondary endpoints were EQ-5D at 1 and 6 months, EQ-5D VAS at 6 months, DAPT withdrawal, need of information regarding DAPT and/or nuisance bleedings, 6-month ischemic and bleeding adverse events.
The EQ5D-VAS was significantly higher in the interventional arm compared to the control arm at 1 and 6 months (8174-88 vs. 7364-80, p < 0.001 at 1 month; 8276-88 vs. 7465-81, p < 0.001 at 6 months). Patients in the interventional arm had also significantly lower pain/discomfort and anxiety/depression at the EQ-5D both at 1 and 6 months. Patients in the control arm withdrew DAPT significantly more (7 (3%) vs. 1 (0.4%), p = 0.03) and looked for information regarding DAPT and/or about nuisance bleeding more frequently than those in the interventional arm (178 (79%) vs.19 (8%), p < 0.001).
The systematic utilization of a multimodal counseling program improved quality of life and reduced the DAPT withdrawal rate in patients on DAPT.

BackgroundThe diagnosis of myocardial infarction (MI) in the presence of heart failure (HF) presents a clinical problem. While diagnostic algorithms using high-sensitivity cardiac troponin have been ...established for suspected MI, their accuracy in patients with HF remains uncertain. This study aims to assess the diagnostic accuracy of high-sensitivity troponin I (TnI) levels in identifying acute MI among patients with HF, focusing on baseline, absolute and relative TnI changes.MethodsData from 562 individuals admitted to the emergency department with suspected MI were retrospectively analysed. Two-point TnI and baseline brain natriuretic peptide (BNP) test results were available. HF status was determined based on clinical, laboratory and instrumental criteria.ResultsAmong the 562 patients, 299 (53.2%) were confirmed having MI. Baseline TnI demonstrated predictive capability for MI in the overall population (area under the curve (AUC) 0.63), while TnI relative change exhibited superior performance (AUC 0.83). Baseline TnI accuracy varied significantly by group, notably decreasing in the third group (severe HF) (AUC 0.54) compared with the first and second groups (AUC 0.67 and AUC 0.71, respectively). TnI relative change demonstrated consistent accuracy across all groups, with AUCs of 0.79, 0.79 and 0.89 for the first, second and third groups, respectively, even after adjustment for age, sex and glomerular filtration rate.DiscussionTroponin relative change is a reliable predictor of MI, even in patients with acute HF. Baseline TnI accuracy is influenced by HF severity. It is essential to consider HF status and BNP levels when employing high-sensitivity cardiac troponin testing to rule out suspected MIs.
Background: Recently, questions around the efficacy and effectiveness of Fractional Flow Reserve (FFR) have arisen in various clinical settings. Methods: The Clinical Outcome of FFR-guided ...Revascularization Strategy of Coronary Lesions (HALE-BOPP) study is an investigator-initiated, multicentre, international prospective study enrolling patients who underwent FFR measurement on at least one vessel. In accordance with the decision-making workflow and treatment, the vessels were classified in three subgroups: (i) angio-revascularized, (ii) FFR-revascularized, (iii) FFR-deferred. The primary endpoint was the occurrence of target vessel failure (TVF, cardiac death, target vessel myocardial infarction and ischemia-driven target vessel revascularization). The analysis was carried out at vessel- and patient-level. Results: 1305 patients with 2422 diseased vessels fulfilled the criteria for the present analysis. Wire-related pitfalls and transient adenosine-related side effects occurred in 0.8% (95% CI: 0.4%–1.4%) and 3.3% (95% CI: 2.5%–4.3%) of cases, respectively. In FFR-deferred vessels, the overall incidence rate of TVF was 0.024 (95% CI: 0.019–0.031) lesion/year. After a median follow-up of 3.6 years, the occurrence of TVF was 6%, 7% and 11.7% in FFR-deferred, FFR-revascularized and angio-revascularized vessels, respectively. Compared to angio-revascularized vessels, FFR-guided vessels (both FFR-revascularized and FFR-deferred vessels) showed a lower TVF incidence rate lesion/year (0.029, 95% CI: 0.024–0.034 vs. 0.049, 95% CI: 0.040–0.061 respectively, p = 0.0001). The result was consistent after correction for confounding factors and across subgroups of clinical interest. The patient-level analysis confirmed the lower occurrence of TVF in negative-FFR vs. positive-FFR subgroups. Conclusions: In a large prospective observational study, an FFR-based strategy for the deferral of coronary lesions is a reliable and safe tool, associated with good outcomes. Clinical Trial Registration: NCT03079739.
Immune checkpoint molecules like cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed cell death 1 (PD-1) or its ligand, programmed cell death ligand 1 (PD-L1), play a critical role in regulating ...the immune response, and immune checkpoint inhibitors (ICIs) targeting these checkpoints have shown clinical efficacy in cancer treatment; however, their use is associated with immune-related adverse events (irAEs), including cardiac complications. The prevalence of cardiac irAEs, particularly myocarditis, is relatively low, but they can become a severe and potentially life-threatening condition, usually occurring shortly after initiating ICI treatment; moreover, diagnosing ICI-related myocarditis can be challenging. Diagnostic tools include serum cardiac biomarkers, electrocardiography (ECG), echocardiography, cardiac magnetic resonance (CMR) and endomyocardial biopsy (EMB). The treatment of ICI-induced myocarditis involves high-dose corticosteroids, which have been shown to reduce the risk of major adverse cardiac events (MACE). In refractory cases, second-line immunosuppressive drugs may be considered, although their effectiveness is based on limited data. The mortality rates of ICI-induced myocarditis, particularly in severe cases, are high (38-46%). Therapy rechallenge after myocarditis is associated with a risk of recurrence and severe complications. The decision to rechallenge should be made on a case-by-case basis, involving a multidisciplinary team of cardiologists and oncologists. Further research and guidance are needed to optimize the management of cancer patients who have experienced such complications, evaluating the risks and benefits of therapy rechallenge. The purpose of this review is to summarize the available evidence on cardiovascular complications from ICI therapy, with a particular focus on myocarditis and, specifically, the rechallenge of immunotherapy after a cardiac adverse event.
Background
The clinical value of cardiopulmonary exercise testing (CPET) in cardiac amyloidosis (CA) is uncertain. Due to the growing prevalence of the disease and the current availability of ...disease‐modifying drugs, prognostic stratification is becoming fundamental to optimizing the cost‐effectiveness of treatment, patient phenotyping, follow‐up, and management. Peak VO2 and VE/VCO2 slope are currently the most studied CPET variables in clinical settings, and both demonstrate substantial, independent prognostic value in several cardiovascular diseases. We aim to study the association of peak VO2 and VE/VCO2 slope with prognosis in patients with CA.
Methods and results
We performed a systematic review and searched for clinical studies performing CPET for prognostication in patients with transthyretin‐CA and light‐chain‐CA. Studies reporting hazard ratio (HR) for mortality and peak VO2 or VE/VCO2 slope were further selected for quantitative analysis. HRs were pooled using a random‐effect model. Five studies were selected for qualitative and three for quantitative analysis. A total of 233 patients were included in the meta‐analysis. Mean peak VO2 resulted consistently depressed, and VE/VCO2 slope was increased. Our pooled analysis showed peak VO2 (pooled HR 0.89, 95% CI 0.84–0.94) and VE/VCO2 slope (pooled HR 1.04, 95% CI 1.01–1.07) were significantly associated with the risk of death in CA patients, with no significant statistical heterogeneity for both analyses.
Conclusions
CPET is a valuable tool for prognostic stratification in CA, identifying patients at increased risk of death. Large prospective clinical trials are needed to confirm this exploratory finding.
