Methods:
Thisstudywasconductedon50patients(30LNpatientsand20SLEpatients
withoutnephritis).TheSLEdiseaseactivityindex(SLEDAI)andSystemic
Lupus InternationalCollaborating Clinics Damage Index (SLICC/DI)were
assessed.Laboratoryinvestigations,cardiacenzymes(Hs-TnTandCKMB),
andtransthoracicechocardiographywereperformed.
