Vasodilation is the process of widening blood vessels, which increases blood flow and pressure through our bodyâs veins, arteries, and arterioles.

Nitric oxide (NO) is an important vasorelaxant released from endothelial cells. There is evidence for reduced activity of the GH-IGF-I axis in patients with chronic heart failure [7,8].Treatment with GH for 3 months has been shown to increase left ventricular mass . The discovery about its role in the cardiovascular system even resulted in the Nobel prize ().The gas is involved in vasodilation, respiration, neurotransmission, hemostasis (prevention of bleeding), and immune response ().However, inhaling nitric oxide can cause systemic effects that can leave one dizzy or lightheaded.
