Background/Objectives: Bempedoic acid (BA) is a novel lipid-lowering agent that reduces low-density lipoprotein cholesterol (LDL-c) and cardiovascular events. Limited real-world data on its effectiveness and safety are available. This study aimed to evaluate the utilization and clinical performance of BA in routine clinical practice. Moreover, an explorative pharmacoeconomic analysis was performed. Methods: We prospectively enrolled consecutive patients with dyslipidemia who started 180 mg BA, alone or with 10 mg ezetimibe, across five outpatient clinics in Campania Region, Italy from September to December 2023. Clinical and laboratory assessments, including lipid profile, hepatic function, and creatine phosphokinase levels, were performed at baseline and at least after one month follow-up. Side effects were recorded. Results: 111 patients (age 65 ± 9 years, 61% male) were included. At BA initiation, 70.3% were on maximally tolerated statin dosage and ezetimibe, 16.2% on ezetimibe alone, and 13.5% on PCSK9 inhibitors due to statin intolerance. BA significantly reduced LDL-c serum levels (89.9 ± 33.0 vs. 56 ± 27.6 mg/dL; p < 0.0001), with 46% achieving therapeutic targets. LDL-c decreased by 28% in patients on intensive statins/ezetimibe and by 45% in statin-intolerant patients, with reduced healthcare costs. Side effects were infrequent (10%) and reversible. Adherence was 99%, and persistence 90%. Conclusions: In our clinical pratice, BA was primarily used in high-risk patients with dyslipidemia who failed to reach LDL-c therapeutic target with statins/ezetimibe, and to a lesser extent, in statin-intolerant individuals. BA treatment enabled 54% to reach LDL-c therapeutic target. BA was well tolerated, and showed high adherence and persistence, contributing to cost savings.

Background: Pulsed field ablation (PFA) is a novel non-thermal modality for pulmonary vein isolation (PVI) in atrial fibrillation (AF), offering myocardial selectivity through irreversible electroporation while sparing surrounding structures. However, concerns have emerged regarding potential subclinical hemolysis, reflected by alterations in biochemical markers such as lactate dehydrogenase (LDH). Methods: We conducted a retrospective, single-center study involving 249 patients undergoing PVI: 121 treated with PFA (PulseSelect or FARAPULSE) and 128 with radiofrequency (RF) ablation (PVAC catheter). Laboratory parameters were assessed at baseline, post-procedure, and at discharge, including hemoglobin, hematocrit, red blood cell (RBC) count, platelet count, creatinine, and LDH. The primary endpoint was the variation in blood cell indices; the secondary endpoint was the evaluation of LDH and hematocrit changes. Statistical analysis included t-tests and chi-square tests. Results: Baseline characteristics and pre-procedural labs did not differ significantly between groups. No significant changes in hemoglobin, hematocrit, RBC count, platelet count, or creatinine were observed post-ablation or at discharge. However, LDH levels significantly increased in the PFA group both post-procedurally and at discharge (p < 0.001), without concurrent changes in other blood cell parameters. Conclusions: PFA and RF ablation yield comparable hematological profiles after PVI, with no significant impact on key blood cell parameters. Nonetheless, the consistent rise in LDH levels in the PFA group suggests mild, subclinical hemolysis or tissue injury due to more extensive lesions. While supporting the hematologic safety of PFA, these findings underscore the need for further studies to assess the clinical significance of these biochemical alterations, particularly in high-risk patients or extensive ablation settings.

Background/Objectives: Vulnerable coronary plaques are strongly associated with acute coronary events, posing significant therapeutic challenges despite statin therapy. This case report evaluates the impact of Evolocumab, a PCSK-9 inhibitor, on stabilizing high-risk plaques and promoting phenotypic transformation, assessed through coronary CT angiography (CCTA). Methods: A 50-year-old male with chronic coronary syndrome and a history of myocardial infarction underwent a CCTA, revealing a high-risk plaque (approximately 50%) in the proximal LAD. Despite achieving LDL-C targets with statin therapy, the plaque showed vulnerability features. Evolocumab (140 mg subcutaneously every two weeks) was added to therapy, combined with dietary counseling and dual antiplatelet therapy. Results: A follow-up CCTA at 24 months demonstrated significant reductions in plaque volume and positive remodeling, with a transformation from a mixed phenotype to a predominantly calcified plaque. LDL-C levels decreased from 71 mg/dL to 18 mg/dL. The patient remained asymptomatic, with no cardiovascular events reported during the follow-up. Conclusions: This case highlights the role of PCSK-9 inhibitors in stabilizing high-risk plaques, achieving structural changes that promote stability beyond LDL-C reduction. Advanced imaging techniques such as CCTA proved essential for risk stratification and monitoring therapy efficacy. Evolocumab offers a promising adjunctive treatment for high-risk patients unsuitable for elective revascularization, potentially redefining the standard of care for plaque stabilization in this setting.

Subclinical coronary atherosclerosis is common but its biological aggressiveness and interplay with extracoronary disease in asymptomatic individuals remain unclear. We evaluated the prevalence of high-risk coronary plaques (HRPs) and their relationship with mild carotid atherosclerosis and coronary calcium in a cardiovascular (CV) high-risk cohort in primary prevention. This retrospective multicenter study enrolled 269 asymptomatic adults with multiple CV risk factors who underwent Coronary Computed Tomography Angiography (CCTA) after prior carotid duplex ultrasound (CDUS). Coronary artery disease (CAD) was graded as absent, non-obstructive (<50% stenosis) or obstructive (≥50%), and HRPs were identified by ≥1 adverse morphological feature (low attenuation, positive remodeling, napkin-ring sign, spotty calcification). Carotid disease was classified as CDUS 0 (no plaque), CDUS 1–49% (mild), or CDUS ≥ 50% (significant). Pre-specified analyses explored prevalence of HRPs across CDUS–calcium-score strata (cut-off 100 Agatston) and independent predictors within the CDUS 1–49% subgroup. CAD was absent in 31%, non-obstructive in 41%, and obstructive in 28%. HRPs were present in 30.9% of all cases, in 26.6% of non-obstructive and in 64.6% of obstructive CAD. HRPs prevalence rose step-wise from 10.0% (CDUS 0 + Ca < 100) to 27.7% (CDUS 1–49% + Ca < 100), 41.2% (CDUS 0 + Ca ≥ 100) and 59.4% (CDUS 1–49% + Ca ≥ 100). In patients with CDUS 1–49%, current smoking independently predicted HRPs (OR 2.1, 95% CI 1.0–4.5; p = 0.049). Nearly one-third of asymptomatic adults with high CV risk already showed HRPs. Mild carotid atherosclerosis synergized with a calcium score ≥ 100 to identify a subgroup in which six of ten individuals exhibited HRPs. Smoking was the only independent clinical correlate identified of plaque vulnerability. Combined carotid ultrasound, calcium scoring and CCTA may substantially refine primary prevention risk stratification beyond traditional factors.

Background: Atypical atrial flutter (AFL) is a complex clinical challenge, particularly in patients with prior atrial fibrillation (AF) treated with pulmonary vein isolation (PVI). Arrhythmias involving the vein of Marshall (VOM) often require extensive lesion sets, including ethanol infusion, to effectively target the epicardial substrate. To minimize tissue damage, an alternative strategy has been proposed, emphasizing advanced electroanatomical mapping, entrainment maneuvers, and highly targeted ablation techniques. Case Presentation: We describe a 72-year-old woman with recurrent atrial arrhythmias following pulmonary vein isolation (PVI), who presented with palpitations as her primary symptom. After ineffective pharmacological therapy, she underwent a catheter ablation procedure. Electroanatomical mapping revealed significant left atrial scarring and suggested a macroreentrant circuit involving the VOM. Entrainment maneuvers confirmed the VOM’s involvement. A single targeted endocardial ablation guided by the ablation index terminated the arrhythmia within 12 s, without the need for ethanol infusion or extensive lesion sets. Discussion: This case underscores the VOM’s role in sustaining atypical AFL post-PVI and highlights the effectiveness of precise electroanatomical mapping combined with targeted endocardial ablation. Unlike broader ablation or ethanol infusion strategies, a focused lesion at the critical isthmus achieved arrhythmia termination with minimal tissue damage. Conclusions: Endocardial ablation at the site of entrainment can safely and effectively treat VOM-related AFL, offering symptom relief and restoration of sinus rhythm. This approach may reduce procedural risks and expand the feasibility of VOM-related arrhythmia management in centers without access to ethanol infusion.

Coronary computed tomography angiography (CCTA) has profoundly changed the diagnostic approach to patients with suspected coronary artery disease (CAD). Originally developed as a non-invasive technique for identifying or ruling out obstructive coronary stenoses, CCTA has progressively evolved into an imaging modality capable of providing a comprehensive assessment of coronary atherosclerosis. A growing body of evidence has demonstrated that the clinical value of CCTA extends far beyond the anatomical evaluation of coronary stenosis. Modern CCTA allows for the quantification of the burden of atherosclerotic plaques, the characterization of plaque composition, the identification of high-risk plaque features, and a more accurate stratification of cardiovascular risk, moving from the concept of ischemia to that of atheroma. In addition to its role in diagnosing CAD and evaluating coronary stents and bypass grafts, CCTA is also becoming increasingly important in procedure planning, cardiovascular prevention, and the personalization of treatment strategies. Overall, this could finally represent a unique opportunity to reduce the cardiovascular burden that still weighs on health care systems. Looking ahead, the growing use of CCTA in clinical practice is creating new diagnostic, interpretive, and organizational challenges. This perspective aims to discuss the evolving role of CCTA and the necessary changes regarding the new competencies required of clinical cardiologists, interventional cardiologists, and cardiovascular radiologists, taking into account the need to redefine technological standards, multidisciplinary training programs, as well as the organization and sustainability of healthcare—including environmental impact and reimbursement models—in order to fully and fairly harness the potential of modern CCTA.
