Screening and diagnosis of atrial fibrillation. Screening for atrial fibrillation (AF) is crucial as this arrhythmia is asymptomatic in a third of patients and 5% of patients present a stroke as the first manifestation of their AF. The European Society of Cardiology recommends opportunistic screening of AF in patients over 65 years of age and systematically in patients over 75 years of age. The simplest way is pulse taking, but the number of connected devices for AF screening allows to multiply the frequency of screening and thus increase sensitivity, with another advantage of a digitalized transmission of the tracing. However many questions remain. No scientific evidence has demonstrated a benefit for AF screening. We do not know what duration and frequency of screening is relevant. The burden of AF which increases thromboembolic risk is not known. What population should be screened and how to consider subclinical AF? We will obtain answers to our questions in the coming years thanks to the results of the various studies in progress.

Aims: Trials on integrated care for atrial fibrillation (AF) showed mixed results in different AF populations using various approaches. The multicentre, randomized AF-EduCare trial evaluated the effect of targeted patient education on unplanned cardiovascular outcomes.
Methods And Results: Patients willing to participate were randomly assigned to in-person education, online education, or standard care (SC) and followed for minimum 18 months.

Chronic heart failure (CHF) is a complex clinical syndrome resulting from various cardiac diseases, characterized by weakened cardiac pumping capacity and inadequate blood supply to body tissues. This study aims to investigate the expression and clinical implications of pro-B-type natriuretic peptide (pro-BNP) and soluble suppression of tumorigenicity 2 (sST2) in CHF to explore their potential in early diagnosis and severity assessment of the pathological condition. This study included 146 CHF patients treated at our hospital from January 2022 to December 2023, who were classified in the observation group, and 150 concurrent healthy people categorized in the control group.

Objective: To evaluate the concentrations of CC-chemokines and stable metabolites of nitric oxide (NO) and endothelin-1 (ET-1) in patients with atherothrombotic (AT) and cardioembolic (CE) subtypes of ischemic stroke (IS) in the acute period.
Material And Methods: Sixty patients diagnosed with IS in the carotid basin were examined. Group 1 included 30 patients with AT, group 2 - 30 patients with CE subtype of IS.

Atrial fibrillation (AF) is recognized as a developing global epidemic responsible for a significant burden of morbidity and mortality. To counter this public health crisis, the advancement of artificial intelligence (AI)-aided tools and methodologies for the effective detection and monitoring of AF is becoming increasingly apparent. A unified strategy from the international research community is essential to develop effective intelligent tools and technologies to support the health professionals for effective surveillance and defense against AF.

Unlabelled: Right-to-left shunt may be a cause of paradoxical embolization (and cryptogenic cerebral ischemic events). Patent foramen ovale and pulmonary arterio-venous malformations are the most common cause of paradoxical embolization; however, some rare cardiovascular lesions may cause a right-to-left shunt with consequent paradoxical embolization. We describe a case of a young child with superior sinus venosus atrial septal defect who underwent surgical closure and developed a cryptogenic cerebral ischemic attack due to a rare cause of paradoxical embolization, during a long-term follow-up.
