Cardiomyopathy Associated with Zinc Deficiency after Bariatric Surgery

Noncompliance with vitamin and mineral supplement protocol after bariatric surgery may lead to true-elements deficiency. Among them, zinc and selenium deficiencies were closely related to cardiac complications, such as myocardial fibrosis, heart failure, and arrhythmias. We describe a 30-year-old female, 6 weeks after delivery and 5 years after bariatric surgery, who was admitted to the cardiology department because of dyspnea and clinical evidence of heart failure, as well as an echocardiogram that demonstrated reduced systolic left ventricular function. Standard antifailure regimen shows mild benefit. Zinc supplements added to treatment lead to significant clinical and echocardiographic improvement.
