Comparison of cardiac structure and function between SLE patients and reference controls (RC) based on cMRI values.

Variable	SLE (n=13)	RC (n=22)	p-value
EF (%)	59 ± 7	64 ± 5	0.0291
LVM/LVEDV (g/mL)	0.66 ± 0.08	0.62 ± 0.07	ns
LVEDVi (mL/m2)	72.02 ± 15.4	67.40 ± 9.3	ns
LVESVi (mL/m2)	29.9 ± 10.2	24.5 ± 5.6	ns
LVSVi (mL/m2)	42.56 ± 8.2	42.92 ± 5.4	ns
LVMi (g/m2)	47.31 ± 9.3	41.34 ± 4.3	0.0454
CI (L/min/m2)	3 ± 1	2.6 ± 0.3	ns
Radial Strain (%)	29.70 ± 6.2	34.37 ± 5.8	0.0306
Circumferential Strain (%)	−17.94 ± 2.5	−19.73 ± 2	0.0251
Longitudinal Strain (%)	−18.40 ± 2.2	−20.10 ± 1.9	0.0202
Native T1 (ms)	1262.5 ± 34.6	1258 ± 47	ns
ECV (%)	28.7 ± 3.1	29.4 ± 2.6	ns

Results are shown as mean ± S.D. and significance was determined using student t test with or without Welch’s correction as appropriate. EF: ejection fraction, LVM: left ventricular mass; LVEDV: left ventricular end diastolic volume; BSA: body surface area; LVEDVi: left ventricular end diastolic volume index (LVEDV/BSA); LVESVi: left ventricular end systolic volume index (LVESV/BSA); LVSVi: left ventricular systolic volume index (LVSV/BSA); LVMi: left ventricular mass index (LVM/BSA); CI: cardiac index; ECV: extracellular volume. ns represents a p-value > 0.05.
