In patients with embolic stroke of undetermined source (ESUS), this can be challenging due to the frequent presence of multiple potential embolic sources, raising difficulties to identify the most likely cause. Additionally, despite targeted preventive measures for the presumed embolic source, patients may remain at risk for stroke and cardiovascular events due to other unrecognized or underestimated pathologies. The multi-level complexity and multimorbidity typically associated with ESUS, represents a challenge that requires broad knowledge of the cardiovascular pathophysiology, deep expertise of the available diagnostic and therapeutic options, and interdisciplinary approach. At the same time, it is an ideal opportunity to assess thoroughly the overall cardiovascular status of the patient, which in turn can allow us to optimize therapeutic and preventive strategies in a holistic approach, and prevent future strokes, cardiovascular events and disability through different parallel pathways. In this context, rather than narrowing our perspective on identifying the specific embolic source presumed to be the most likely cause of ESUS, it is crucial to shift our focus from the disease to the patient, and evaluate the overall cardiovascular profile by assessing the risk of all cardiovascular comorbidities present, no matter if causally associated with ESUS or not. In order to bring across these points and more, this article is centred around a clinical case that serves as a starting point to illustrate the holistic approach to the management of patients with ESUS. After all, this is the beauty, the magic and the art of Internal Medicine: to treat the patient, not the disease, the system or the organ.</p>","PeriodicalId":50485,"journal":{"name":"European Journal of Internal Medicine","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142512195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite optimal treatment, some patients remain symptomatic due to the disease's heterogeneity, manifesting in various phenotypes. One notable phenotype involves eosinophilic inflammation, with a variable prevalence. Identifying eosinophilic phenotypes is crucial for tailored therapeutic strategies, as they respond favorably to corticosteroids and potentially biologics. Recent advances in both clinical trials and spontaneous research have helped understand the biological and clinical characteristics of this phenotype, although no universal consensus has been reached yet on the definition of the cut-off values of the eosinophil peripheral blood count. Moreover, there is evidence of novel emerging biomarkers which might go beyond the sole eosinophil count, while significant advancements in terms of pharmacological treatment have been made, with dupilumab being the first biological drug being licensed for COPD patients with elevated circulating eosinophils in the stable phase.
