Vitamin D deficiency is associated with arterial stiffness, a risk factor for heart disease and stroke, in black teens. Researchers measured arterial stiffness in study subjects using pulse wave velocity (PWV), a non–invasive procedure where a pulse is emitted at two arterial sites. The pulse's transit time and distance travelled help researchers reliably calculate arterial stiffness. Results from the study showed that vitamin D may protect vascular systems and that sufficient supplementat ... Click Here to Read More Click Here to Read More
