BACKGROUND: Psoriasis is a chronic inflammatory skin disease associated with multiple comorbidities including psoriatic arthritis (PsA), atherosclerotic disease, metabolic syndrome, diabetes, hypertension, obesity, and depression. Interestingly, nonischemic cardiomyopathy, especially dilated cardiomyopathy (DCM), has been associated with psoriasis and reported in only in a few cases in the literature.
CASE REPORT: We report the rare case of a 58-year-old man with a medical history of untreated severe psoriasis and PsA who presented with a sudden onset of shortness of breath. Laboratory and radiographic studies showed an elevated level of B-type natriuretic peptide and acute bilateral pulmonary edema. The patient had normal coronary arteries on cardiac catheterization and echocardiography showed newly diagnosed DCM with systolic and diastolic dysfunction. Cardiac magnetic resonance imaging was consistent with nonischemic DCM (NIDCM) with no evidence of hypertrophy, infiltrative process, or edema. The patient was diagnosed with acute congestive heart failure secondary to NIDCM in the setting of long-standing untreated psoriasis. He responded well to diuretics, was placed on guideline-directed medical therapy, and was discharged with a LifeVest personal cardiac defibrillator. As an outpatient, the patient was started on secukinumab, a monoclonal antibody against interleukin-17A. At his last follow-up appointment, the patient reported improvement in his cardiac symptoms and resolution of his psoriatic skin lesions; repeat echocardiography showed improvement in his ejection fraction.
CONCLUSIONS: Although studies have shown a higher prevalence of cardiovascular disease in patients with psoriasis, an association with NIDCM has not been studied sufficiently. We recommend further studies of the prevalence, pathogenesis, screening, and management of NIDCM in patients with psoriasis.
