The use of increasingly complex cardiac implantable electronic devices (CIEDs) has increased exponentially in recent years. One of the most serious complications in terms of mortality, morbidity and financial burden is represented by infections involving these devices. They may affect only the generator pocket or be generalised with lead-related endocarditis. Modifiable and non-modifiable risk factors have been identified and they can be associated with patient or procedure characteristics or with the type of CIED. Pocket and systemic infections require a precise evaluation and a specialised treatment which in most cases involves the removal of all the components of the device and a personalised antimicrobial therapy. CIED retention is usually limited to cases where infection is unlikely or is limited to the skin incision site. Optimal re-implantation timing depends on the type of infection and on the results of microbiological tests. Preventive strategies, in the end, include antibiotic prophylaxis before CIED implantation, the possibility to use antibacterial envelopes and the prevention of hematomas. The aim of this review is to investigate the pathogenesis, stratification, diagnostic tools and management of CIED infections.

Spontaneous coronary artery dissection (SCAD) is a rare clinical condition, but frequently manifested as acute myocardial infarction. In this particular setting, in recent years, optical coherence tomography (OCT) has been established as a possible diagnostic method due to the high spatial resolution (10–20 μm), which can visualize the different layers of coronary vessels. OCT can better analyze the “binary” or double lumen morphology, typical of this entity. Furthermore, it can identify the entrance breach and the circumferential and longitudinal extension of the lesion. However, we have to emphasize that this technique is not free from complications. OCT could further aggravate a dissection or exacerbate a new intimal tear. Therefore, the use of OCT in the evaluation of SCAD should be defined by balancing the diagnostic benefits versus procedural risks. Moreover, we underline that as SCAD is a rare condition and OCT is a recently introduced technique in clinical practice, limited data is available in literature.

Background/Objectives: This study assessed the proportion of secondary cardiovascular prevention patients who achieved low-density lipoprotein (LDL) cholesterol targets as per the 2019 ESC/EAS Dyslipidemia Guidelines. We also evaluated whether lipid-lowering therapies (LLTs) were adjusted in patients not meeting targets and analyzed the likelihood of these modifications achieving recommended levels. Methods: A multicenter, cross-sectional observational study retrospectively reviewed medical records of 1909 outpatients in 9 Italian cardiac rehabilitation/secondary prevention clinics from January 2023 to June 2024. Inclusion criteria included prior atherosclerotic cardiovascular disease (ASCVD) and recent LDL-cholesterol levels. Data included demographics, ASCVD presentation, lipid profiles, and LLTs. Patients at very high risk had LDL targets of ≤55 mg/dL, or ≤40 mg/dL for recurrent events within 2 years. Clinicians’ approaches to LLT modification in patients not at target were recorded, with LLT efficacy estimated based on percentage distance from LDL-cholesterol targets. Results: Of the 1909 patients, 41.3% met the LDL-cholesterol target. Predictors of achieving targets included male gender, cardiac rehabilitation, recent acute coronary syndrome, diabetes, and triple therapy (statin + ezetimibe + PCSK9 inhibitors). Conversely, a target of ≤40 mg/dL, lack of therapy, and monotherapy were negative predictors. Among 1074 patients not at target, LLT modifications were proposed for 48.6%. Predictors of LLT modification included recent ASCVD events, cardiac rehabilitation, and greater percentage distance from the LDL target, while advanced age and an LDL target of ≤40 mg/dL were negative predictors. However, only 42.3% of modified therapies were predicted to be effective in reaching LDL targets. Conclusions: Despite 2019 ESC/EAS guidelines, a significant proportion of high-risk patients did not achieve LDL targets, and proposed LLT modifications were often insufficient. More intensive LLT regimens are needed to improve outcomes in this population.

Background: The impact of complete revascularization (CR) on the development of heart failure (HF) in patients with acute coronary syndrome and multivessel coronary artery disease undergoing percutaneous coronary intervention remains to be elucidated. Methods and Results: Consecutive patients with acute coronary syndrome with multivessel coronary artery disease from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of first hospitalization for HF or cardiovascular death was the primary end point. Patients were stratified according to completeness of coronary revascularization. Of 14 699 patients in the CORALYS registry, 5054 presented with multivessel disease. One thousand four hundred seventy‐three (29.2%) underwent CR, while 3581 (70.8%) did not. Over 5 years follow‐up, CR was associated with a reduced incidence of the primary end point (adjusted hazard ratio [HR], 0.66 [95% CI, 0.51–0.85]), first HF hospitalization (adjusted HR, 0.67 [95% CI, 0.49–0.90]) along with all‐cause death and cardiovascular death alone (adjusted HR, 0.74 [95% CI, 0.56–0.97] and HR, 0.56 [95% CI, 0.38–0.84], respectively). The results were consistent in the propensity‐score matching population and in inverse probability treatment weighting analysis. The benefit of CR was consistent across acute coronary syndrome presentations (HR, 0.59 [95% CI, 0.39–0.89] for ST‐segment elevation myocardial infarction and HR, 0.71 [95% CI, 0.50–0.99] for non‐ST‐elevation acute coronary syndrome) and in patients with left ventricular ejection fraction >40% (HR, 0.52 [95% CI, 0.37–0.72]), while no benefit was observed in patients with left ventricular ejection fraction ≤40% (HR, 0.77 [95% CI, 0.37–1.10], P for interaction 0.04). Conclusions: CR after acute coronary syndrome reduced the risk of first hospitalization for HF and cardiovascular death, as well as first HF hospitalization, and cardiovascular and overall death both in patients with ST‐segment elevation myocardial infarction and non‐ST‐elevation acute coronary syndrome.
