Strain atriale derivato dalla risonanza magnetica cardiaca ristruttura i pazienti con cardiomiopatia ipertrofica a basso rischio di morte cardiaca improvvisa.

AIMS: Hypertrophic cardiomyopathy (HCM) is associated with diverse cardiovascular outcomes. Whilst the HCM Risk-SCD score effectively stratifies sudden cardiac death (SCD) risk, it provides limited insight into global cardiovascular prognosis, particularly amongst low-risk patients (HCM Risk-SCD score <4%). Left atrial global longitudinal strain (LA-GLS), derived from cardiovascular magnetic resonance (CMR), may enhance risk stratification. This study aimed to assess the prognostic value of CMR-derived LA-GLS in predicting major adverse cardiovascular events (MACE) in a cohort of low-risk HCM patients. METHODS AND RESULTS: In this retrospective longitudinal single-centre study, 183 low-risk
