Comparing LA parameters between individuals with and without cardiovascular disease

LA parameter	Total (n = 536)	No cardiovascular disease (n = 395)	With cardiovascular disease (n = 141)	P-value
LA maximum volume index, mm3/m2	27.8$\pm$10.4	26.8$\pm$9.6	32.1$\pm$12.5	<0.001
LA minimum volume index, mm3/m2	15.1$\pm$7.1	14.2$\pm$6.0	19.4$\pm$9.7	<0.001
Total LAEF, %	46.5$\pm$9.9	47.6$\pm 9.2$	41.5$\pm$11.4	<0.001
Passive LAEF, %	20.7$\pm$9.7	21.4$\pm$9.9	17.9$\pm$8.3	0.002
Active LAEF, %	31.6$\pm$10.9	32.3$\pm$10.6	28.8$\pm$11.3	0.003
LA maximum strain	28.5$\pm$11.7	28.8$\pm$11.6	27.0$\pm$12.3	0.086

The association between LA parameters and incidence of cardiovascular events was assessed using Cox proportional hazards. Failure time in the individuals with incident CVD was the time between the baseline CMR and the time of the diagnosis. For participants without cardiovascular events, the failure time was the time between baseline examination and the latest follow-up, death, or loss to follow-up.
