The aim of this study is to investigate whether increasing the frequency of neurological and nuclear magnetic resonance screening may affect anxiety and the perception of disease control in patients treated with natalizumab. A total of 62 relapsing-remitting multiple sclerosis patients were recruited from 2019 to 2020.

Prediction of All-Cause Mortality Following Percutaneous Coronary Intervention in Bifurcation Lesions Using Machine Learning Algorithms.

Stratifying prognosis following coronary bifurcation percutaneous coronary intervention (PCI) is an unmet clinical need that may be fulfilled through the adoption of machine learning (ML) algorithms to refine outcome predictions. We sought to develop an ML-based risk stratification model built on clinical, anatomical, and procedural features to predict all-cause mortality following contemporary bifurcation PCI. Multiple ML models to predict all-cause mortality were tested on a cohort of 2393 patients (training, n = 1795; internal validation, n = 598) undergoing bifurcation PCI with contemporary stents from the real-world RAIN registry.

[Devices for the prevention of contrast-induced acute kidney injury in interventional cardiology].

Contrast-induced acute kidney injury (CI-AKI) consists in acute decline in renal function following iodinated contrast media exposure. It has a significant impact on long-term prognosis and mortality, development of chronic kidney disease and on the rate of hospitalization due to cardiovascular or renal events. Anamnestic and procedural aspects linked to higher risk of CI-AKI have been investigated and new devices have been designed in order to prevent it.

Methods: All 506 patients enrolled in the RAIN study, undergoing PCI in a vessel with a diameter 2.5 mm or less were retrospectively evaluated and divided into two groups according to stent strut thickness: 74 μm (n = 206) versus 81 μm (n = 300); 87.

A Sex-Based Analysis From the RAIN-CARDIOGROUP VII Study (VeRy Thin Stents for Patients With Left MAIn or BifurcatioN in Real Life) on Left Main Stenting.

Introduction: There is a lack of data on clinical outcomes of percutaneous coronary intervention (PCI) with ultrathin stents on unprotected left main (ULM) coronary artery comparing women and men.

Methods: All patients treated with ULM-PCI with ultrathin stents (struts ≤81 μm) enrolled in the RAIN-CARDIOGROUP VII study were analyzed according to a sex-assessment evaluation. Major adverse cardiovascular event (MACE, a composite of all-cause death, myocardial infarction, target-lesion revascularization [TLR], and stent thrombosis) was the primary endpoint, whereas single components of MACE were the secondary endpoints.

Using the coronary lithotripsy system for coronary artery disease.

Severe coronary artery calcification increases percutaneous treatment complexity and the risk of intraprocedural complications, affecting acute and long-term outcomes. Current use of specialty balloons and atherectomy technologies is limited due to the higher risk of complications, degree of technical difficulty and operator experience. Intravascular lithotripsy (IVL) is a novel technology for severe calcified coronary artery disease that facilitates vessel preparation, enhancing vessel compliance.

[Management of coronary perforations during angioplasty].

Coronary perforation represents a terrible complication of percutaneous coronary intervention (PCI) which, if not promptly recognized and treated, can lead to catastrophic consequences for the patient. Hence, acquisition of the basic techniques for the treatment of coronary perforations is critical for the interventional cardiologist in order to safely perform PCIs. Although the incidence of coronary perforations remains low during PCI, it is possible to recognize some subgroups of patients and some types of coronary lesions, such as chronic coronary total occlusions, that are associated with increased risk.
