Congestive cardiomyopathy and the selenium content of serum.
A deficiency of selenium is suspected to be involved in the pathogenesis of congestive cardiomyopathy. Therefore the serum selenium content of 20 patients with proven congestive cardiomyopathy was measured and compared to that of a healthy control group. The serum selenium content of the patients with cardiomyopathy was found to be different from that of the healthy control group. The mean value of selenium in serum for the control group was 80.1 micrograms Se/1 (SD +/- 13.2) within a range of 53 and 117 micrograms Se/1. From the 20 patients with congestive cardiomyopathy six patients showed selenium concentrations in the normal value range of the control group; in the serum of 14 patients a distinct lower selenium content was found (mean value 47.8 micrograms Se/1 (SD +/- 16.2)) within a range of 23 and 70 micrograms Se/1. A positive correlation was found between serum selenium content and the left ventricular ejection fraction. Our results suggest that a deficiency of selenium may be present in a number of patients with congestive cardiomyopathy.
