Recent data on the use of hydroxychloroquine in the treatment of SARS-CoV-2 infection have cast doubt on its cardiac safety. The factors associated with CHF, including therapy with antimalarials, were analyzed in a large multicenter SLE cohort. Cross-sectional study including all patients with SLE (ACR-1997 criteria) included in the Spanish Society of Rheumatology Lupus Register (RELESSER), based on historically gathered data. Patients with CHF prior to diagnosis of SLE were excluded. A multivariable analysis exploring factors associated with CHF was conducted. The study population comprised 117 patients with SLE (ACR-97 criteria) and CHF and 3,506 SLE controls. Ninety percent were women. Patients with CHF were older and presented greater SLE severity, organ damage, and mortality than those without CHF. The multivariable model revealed the factors associated with CHF to be ischemic heart disease (7.96 [4.01-15.48], p  Patients with SLE and CHF experience more severe SLE. Treatment with antimalarials appears to confer a cardioprotective effect.enAntimalarialsChronic heart failureSystemic lupus erythematosusAntimalarialsCOVID-19Cross-Sectional StudiesFemaleHeart FailureHumansLupus Erythematosus, SystemicRegistriesRheumatologySARS-CoV-2Antimalarials exert a cardioprotective effect in lupus patients: Insights from the Spanish Society of Rheumatology Lupus Register (RELESSER) analysis of factors associated with heart failure.research article35033377open access10.1016/j.semarthrit.2021.11.0121532-866XPMC8720299https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8720299https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8720299/pdf
