Acute coronary syndrome (ACS) is a complex clinical syndrome that encompasses acute myocardial infarction (AMI) and unstable angina (UA). Its underlying mechanism refers to coronary plaque disruption, with consequent platelet aggregation and thrombosis. Inflammation plays an important role in the progression of atherosclerosis by mediating the removal of necrotic tissue following myocardial infarction and shaping the repair processes that are essential for the recovery process after ACS. As a chronic inflammatory disorder, atherosclerosis is characterized by dysfunctional immune inflammation involving interactions between immune (macrophages, T lymphocytes, and monocytes) and vascular cells (endothelial cells and smooth muscle cells). New-onset atrial fibrillation (NOAF) is one of the most common arrhythmic complications in the setting of acute coronary syndromes, especially in the early stages, when the myocardial inflammatory reaction is at its maximum. The main changes in the atrial substrate are due to atrial ischemia and acute infarcts that can be attributed to neurohormonal factors. The high incidence of atrial fibrillation (AF) post-myocardial infarction may be secondary to inflammation. Inflammatory response and immune system cells have been involved in the initiation and development of atrial fibrillation. Several inflammatory indexes, such as C-reactive protein and interleukins, have been demonstrated to be predictive of prognosis in patients with ACS. The cell signaling activation patterns associated with fibrosis, apoptosis, and hypertrophy are forms of cardiac remodeling that occur at the atrial level, predisposing to AF. According to a recent study, the presence of fibrosis and lymphomononuclear infiltration in the atrial tissue was associated with a prior history of AF. However, inflammation may contribute to both the occurrence/maintenance of AF and its thromboembolic complications.

Radial artery spasm (RAS) is a common complication associated with transradial access (TRA) for coronary interventions, particularly affecting elderly patients in whom radial access is preferred due to its benefits in reducing bleeding complications, improving clinical outcomes, and lowering long-term costs. This review examines the incidence, prevention, and treatment of RAS. Methods included an online search of PubMed and other databases in early 2024, analyzing meta-analyses, reviews, studies, and case reports. RAS is characterized by a sudden narrowing of the radial artery due to psychological and mechanical factors with incidence reports varying up to 51.3%. Key risk factors include patient characteristics like female sex, age, and small body size as well as procedural factors such as emergency procedures and the use of multiple catheters. Preventive measures include using distal radial access, hydrophilic sheaths, and appropriate catheter sizes. Treatments involve the intraarterial administration of nitroglycerine and verapamil as well as mechanical methods like balloon-assisted tracking. This review underscores the need for standardizing RAS definitions and emphasizes the importance of operator experience and patient management in reducing RAS incidence and improving procedural success.

Background/Objectives: Cardiac resynchronization therapy (CRT) and angiotensin receptor–neprilysin inhibitors (ARNIs) are cornerstone therapies for patients with heart failure with reduced ejection fraction (HFrEF). However, nearly 30% of patients show no significant response to CRT alone. The potential of ARNI to enhance CRT outcomes—especially in non-responders—is an emerging field of interest. The objective of this review is to systematically evaluate and synthesize the available evidence on the clinical outcomes of combining CRT with ARNI therapy in patients with HFrEF. Methods: We conducted a comprehensive search of PubMed, Scopus, and Google Scholar up to September 2024, using the keywords “CRT and ARNI” and “cardiac resynchronization therapy and sacubitril/valsartan”. We included retrospective and prospective clinical studies, observational studies, and review articles reporting on patients with HFrEF treated with both CRT and ARNI. Studies not in English, animal studies, and those without full-text availability were excluded. Study selection and data extraction were performed in duplicate by independent reviewers, using PRISMA guidelines for transparency. The final selection included 8 studies published in the last four years, summarized by design, population, outcomes, and statistical significance. Results: The reviewed studies suggest that ARNI therapy, when combined with CRT, may contribute to improvements in left ventricle ejection fraction (LVEF), NYHA functional class, and ventricular remodeling, particularly in CRT non-responders. Some studies also report a potential reduction in ventricular arrhythmias and implantable cardioverter-defibrillator (ICD) interventions. However, outcomes varied across subgroups, and the influence of ARNI timing relative to CRT implantation remains inconclusive. Limitations: Heterogeneity in study designs and small sample sizes in some included studies limited the ability to conduct a meta-analysis. This review is not registered. Conclusions: ARNI therapy shows promise in enhancing CRT response in patients with HFrEF, particularly in non-responders. Further large-scale, prospective studies are needed to clarify optimal patient selection and treatment sequencing.

This review aims to summarize the global prevalence of healthcare-associated infections in patients with acute heart failure who have been admitted to coronary care units, highlighting the underrepresented burden of infection in this high-risk population. Coronary care units (CCUs) play a pivotal role in the care of patients experiencing acute or decompensated heart failure, offering a highly monitored environment with immediate access to advanced cardiac interventions. The management of heart failure in CCUs involves a multidisciplinary approach that includes hemodynamic monitoring, pharmacologic therapy, respiratory support, and, in selected cases, mechanical circulatory assistance. The early identification of deterioration, rapid therapeutic escalation, and close monitoring of cardiac function are hallmarks of CCU care. However, the complexity and severity of illness in this population are compounded by a high risk of infections, including hospital-acquired pneumonia, bloodstream infections, and device-related infections. These infections not only increase morbidity and prolong hospitalization but also significantly impact mortality and healthcare costs. The immunocompromised state of many heart failure patients—due to poor perfusion, malnutrition, and the use of invasive devices—further elevates their vulnerability. Effective infection prevention, early diagnosis, and targeted antimicrobial therapy are, therefore, critical components of heart failure management within CCUs. This intersection of advanced cardiac care and infection control highlights the need for integrated, multidisciplinary strategies to improve outcomes in this high-risk population.

Congenital heart diseases (CHD) are one of the most common birth defects and the main leading cause of death in children. Many patients with CHD are reaching adulthood due to the success of improved contemporary surgical procedures. Understanding the etiology of CHD remains important for patient clinical management. Both genetic and environmental factors are involved in the development and progression of CHD. Variations in many different genes and chromosomal anomalies can be associated with CHD, by expression of different mechanisms. Sporadic cases are the most frequently encountered in these patients. Atrial septal defect is a common congenital heart disease that refers to direct communication between atrial chambers, found isolated or associated with other syndromes. Imaging techniques, especially transthoracic and transesophageal echocardiography (TOE) represent the key for diagnosis and management of ASD. The disease has a major incidence in adulthood, due to late symptomatology, but assessment and treatment are important to avoid time-related complications. Ebstein’s anomaly is a rare congenital disease, with a dominant genetic participation, characterized by an abnormal displacement of the tricuspid valve and right ventricular myopathy, often requiring surgical intervention. Alongside echocardiography, cardiac magnetic resonance (CMR) imaging is the gold standard tool for the assessment of ventricular volumes. Early diagnosis and adequate treatment are mandatory to avoid possible complications of CHD, and thus, ECG, as well as imaging techniques, are important diagnostic tools. However, patients with CHD need a special healthcare team for the entire monitorization in various life stages.

Heart failure with reduced ejection fraction (HFrEF) continues to impose a high burden of morbidity and mortality despite significant advances in pharmacologic and device-based therapy. Cardiac resynchronization therapy (CRT) and angiotensin receptor–neprilysin inhibitors (ARNIs) have independently demonstrated substantial benefits in symptoms, health-related quality of life (HRQoL), and survival. Cardiac rehabilitation (CR), incorporating structured exercise, education, and lifestyle optimization, is well established as an effective intervention in HFrEF, yet its role in the era of combined CRT and ARNI therapy remains insufficiently characterized. This literature review synthesizes current evidence on CR in HFrEF populations receiving CRT, ARNI, or both, highlighting its impact on HRQoL, exercise capacity, and functional outcomes. Across diverse study designs—including randomized trials, observational cohorts, and meta-analyses—CR consistently yielded clinically meaningful improvements in patient-reported HRQoL and objective measures such as six-minute walk distance (6MWD) and peak oxygen uptake. Data directly evaluating CR in patients concurrently receiving both CRT and ARNI are lacking; indirect evidence suggests CR is compatible with, and may add to, contemporary device and drug therapy. However, referral rates remain low, indicating an implementation gap despite strong evidence of benefit. The review underscores the importance of integrating CR into contemporary HFrEF care and identifies a pressing need for targeted prospective studies to define its role in patients receiving dual device–pharmacologic therapy.
