Nitroglycerine, a 100 year old explosive and heart medicine

In atherosclerosis, plaques reduce blood flow in the arteries. This decreases oxygen supply to the heart muscle causing chest pain (angina pectoris) and sometimes even myocardial infarction. Treatment with nitroglycerine provides NO, dilates the vessels, and increases blood flow. Thanks to this year's Nobel Laureates we now understand how nitroglycerine, an important heart medicine, works. It acts as a NO donor, causes dilation of the blood vessels, increases oxygen supply and protects the heart from damage and cell death.
