Summary of patient demographics, study characteristics, and study findings for the three CMR studies

Author, year	HCM, n	Control, n/matched by	LA strain measurement software	Measurement method	Views of measured LA strain	Follow-up, months	Key findings
Hinojar et al. [13], 2018	75	75/age and sex	Cvi 42	Standard CMR-FT	2-, 3- and 4-chamber views	39.6	LA longitudinal strain by CMR-FT may become a novel potential predictor of poor cardiac outcomes
Yang et al. [14], 2021	359	100/age	Medis2.0, Qstrain	A fast LA long-axis strain method	2-and 4-chamber views	40.9	Fast LA GLS reservoir and conduit emerged as independent predictors of the composite adverse events
Zhou et al. [23], 2022	60	60/sex	Medis3.1, QStrain	Standard CMR-FT	2-, 3- and 4-chamber views	81.6	Impaired LA GLS reservoir and booster were associated with clinical outcomes in patients at the early stage of hypertension and HCM

HCM, hypertrophic cardiomyopathy; CMR, cardiac magnetic resonance; NR, no reported; CMR-FT, cardiac magnetic resonance feature tracking LA, left atrium; GLS, global longitudinal strain
