However, the exact mechanism of HCQ cardiotoxicity remains unclear and it is difficult to identify risk factors. We present a case of twin sisters who both suffered from systemic lupus erythematosus (SLE) and HCQ-induced cardiomyopathy presenting with decompensated heart failure (HF), suggesting that genetic predisposition might be a factor in HCQ-induced cardiomyopathy.

Hydroxychloroquine (HCQ) is one of the antimalarial drugs that have been used for decades to treat rheumatic diseases (1).

Patients with systemic lupus erythematosus SLE can present with multiple cardiovascular pathologies, including pulmonary hypertension, valvular disease, pericarditis, myocarditis, and premature atherosclerosis. SLE medications can also cause cardiovascular side effects. We present a patient who developed a severe cardiomyopathy secondary to the hydroxychloroquine prescribed to treat her SLE. Hydroxychloroquine HCQ, a common anti-rheumatic medication, can be cardiotoxic and cause systolic or diastolic heart failure HF. A 65 year old man presented with acute decompensated HF.
