Correlation between cardiovascular magnetic resonance features and clinical characteristics of cardiac involvement in connective tissue diseases.

Objectives: Patients with connective tissue diseases (CTD) have a high incidence of cardiac involvement, which often presents insidiously and can progress rapidly, making it one of the leading causes of death. Multiparametric cardiovascular magnetic resonance (CMR) provides a comprehensive quantitative evaluation of myocardial injury and is emerging as a valuable tool for detecting cardiac involvement in CTD. This study aims to investigate the correlations between CMR features and serological biomarkers in CTD patients, assess their potential clinical value, and further explore the impact of pre-CMR immunotherapy intensity on CMR-specific parameters, thereby evaluating the role of CMR in the early diagnosis of CTD-related cardiac involvement.

Background: Given the divergence in recommendations regarding the relevance of inducible ischemia regarding the indication to revascularize chronic total occlusions (CTOs) among European and North American guidelines, we aim at investigating the prevalence and the prognostic impact of significant inducible ischemia in an unselected cohort of asymptomatic CTO patients, integrating collateralization status and viability assessment with stress cardiac magnetic resonance (CMR).
Methods: From a cohort of 749 patients referred to our center with a diagnosis of CTO, we retrospectively analyzed 111 asymptomatic individuals who underwent an adenosine stress CMR. The amount of inducible ischemia subtended by the CTO was calculated, as well as the presence of viable myocardium and the collateralization status.

Cardiovascular magnetic resonance (CMR) imaging is an established non-invasive tool for the assessment of cardiovascular diseases, which are the leading cause of death globally. CMR provides dynamic and static multi-contrast and multi-parametric images, including cine for functional evaluation, contrast-enhanced imaging and parametric mapping for tissue characterization, and MR angiography for the assessment of the aortic, coronary and pulmonary circulation. However, clinical CMR imaging sequences still have some limitations such as the requirement for multiple breath-holds, incomplete spatial coverage, complex planning and acquisition, low scan efficiency and long scan times.

Background: Diagnosing the cause of undifferentiated left ventricular hypertrophy (LVH) in a patient with progressive heart failure symptoms can present a diagnostic challenge, with potential for both inherited and acquired aetiologies. Hydroxychloroquine-induced cardiomyopathy (HCQ-CM) is a rare complication of long-term hydroxychloroquine use. This case report highlights its clinical presentation, key differential diagnoses, and treatment strategies.

Background And Aims: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) reduce major atherosclerotic cardiovascular events in individuals living with either diabetes or obesity. Since the turnover of vascular regenerative (VR) stem and progenitor cells has been demonstrated to modulate vessel repair and atherothrombotic risk, this study aimed to determine the effect of the GLP-1RA semaglutide on the levels of circulating VR cells.
Methods: SEMA-VR CardioLink-15 was a randomized translational trial of usual care vs.
