Early detection of subclinical myocardial dysfunction may improve risk stratification, and global longitudinal strain (GLS) is emerging as a sensitive marker of early cardiac impairment. Methods: We conducted a single-center observational cohort study including 518 adult patients undergoing autologous (n = 64) or allogeneic (n = 454) HSCT between 2004 and 2025. Baseline cardiovascular risk factors, transplant characteristics, and echocardiographic parameters\u2014including GLS in a subset\u2014were recorded. Abnormal GLS was defined as less negative than \u221220%. The primary outcome was the occurrence of cardiovascular events (composite of cardiovascular death, myocardial infarction, stroke, atrial fibrillation\/flutter, pericardial effusion, pulmonary embolism, and left ventricular systolic dysfunction). Multivariable logistic regression was used to identify independent predictors. Results: Median age was 53 years; 58% were male. Cardiovascular events were predominantly atrial fibrillation, pericardial effusion, and reduced left ventricular function, whereas ischemic events were rare. Over 90% of events occurred within 100 days post-transplant. Multivariable analysis identified older age (OR 1.28 per 10-year increment; 95% CI 1.10\u20131.48; p = 0.002), chronic kidney disease (OR 2.44; 95% CI 1.18\u20135.02; p = 0.01), pre-transplant atrial fibrillation (OR 2.12; 95% CI 1.04\u20134.31; p = 0.03), and abnormal baseline GLS (OR 1.89; 95% CI 1.02\u20133.52; p = 0.04) as independent predictors. Importantly, the prognostic value of GLS remained significant after excluding clinically insignificant pericardial effusions from the composite endpoint. GLS deterioration during follow-up occurred more frequently in patients receiving reduced-intensity conditioning compared with myeloablative conditioning (25% vs. 12.7%; p = 0.006). Conclusions: Subclinical myocardial dysfunction detected by GLS identifies HSCT recipients at increased cardiovascular risk. These findings support the incorporation of strain imaging into routine pre- and post-transplant cardiovascular evaluation to enable earlier detection and guide targeted interventions.<\/jats:p>","DOI":"10.3390\/cancers18121871","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T16:25:16Z","timestamp":1780935916000},"page":"1871","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cardiovascular
