Left and right ventricular function by echocardiography, tissue doppler imaging, carotid intima media thickness, and asymmetric dimethylarginine levels in female adolescents with vitamin D deficiency.

The results of this study demonstrate that vitamin D deficiency in female adolescence is associated with normal myocardial geometry and function. Although it has been associated with normal levels of asymmetric dimethyl arginine concentration, high measured carotid intima-media thickness may reflect endothelial dysfunction.
