Selenium Status and Echocardiographic Parameters in Iraqi Patients with Idiopathic Dilated Cardiomyopathy
Iraqi Postgraduate Medical Journal,
2007, Volume 6, Issue 1, Pages 45-48
It has been speculated that trace elements may play a role in the pathogenesis of dilated cardiomyopathy (DCM) .In the present study, we aimed to assess serum concentrations of selenium (Se) in Iraqi patients with idiopathic dilated cardiomyopathy (IDC) and to evaluate the correlation between serum Se concentrations and echocardiographic parameters.
This study included 28 patients with IDC and 22 healthy controls .Serum level of selenium was measured by atomic absorption spectrophotometry method .Echocardiographic parameters including left ventricular end diastolic diameter (LVEDD), LV end- systolic diameter (LVESD) ,and LV ejection fraction (LVEF) were measured in all patients with IDC in order to evaluate its correlation with serum Se concentrations.
Serum concentration of Se in IDC patients was significantly lower than in healthy controls (p<0.001).Relationships of the serum Se levels with echocardiographic and clinical parameters were not statistically significant.
The present study confirmed that IDC is associated with decreased serum Se concentrations. This change in Se may play an important role in the pathogenesis of myocardial damage in IDC
