Table 2. Myocardial strain and EFV parameter analysis.

Variables	MVO (n=22)	NMVO (n=34)	t	P
GRS (%)	14.64±5.87	21.98±6.70	4.20	<0.001
GCS (%)	−10.90±4.89	−16.06±5.36	−3.64	<0.001
GLS (%)	−5.91±2.63	−10.62±3.01	−5.99	<0.001
EFV (cm3)	83.73±16.52	58.06±15.36	−5.93	<0.001

Data are presented as mean ± standard deviation. Negative values of GCS and GLS indicate that the myocardium has undergone normal physiological shortening during the contraction process, which is a part of the heart’s pumping function. EFV, epicardial fat volume; MVO, microvascular obstruction; NMVO, non-microvascular obstruction; GRS, global radial strain; GCS, global circumferential strain; GLS, global longitudinal strain.
