Researchers are looking for underlying mechanisms and new ways to combat this epidemic. Over the past decade, evidence has accumulated indicating that nitric oxide (NO) may play a key role in the control of metabolic and cardiovascular homeostasis, as evidenced by mice lacking the gene for endothelial nitric oxide synthase (eNOS) that are insulin resistant and hypertensive. An animal study now finds that stimulating NO bioavailability by lipid lowering statins may represent a new way to combat this epidemic.
Statins are a group of compounds that have been used successfully to lower cholesterol and prevent myocardial infarction. A less well known effect of statins is that they augment NO bioavailability in circulation. Abnormalities in the body's production of NO have been implicated in high blood pressure, atherosclerosis (narrowing of the arteries), diabetes, impotence, and stroke.
One statin is the prescription drug Simvastatin, used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in the blood. Accumulation of cholesterol and fats along the walls of the arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to the heart, brain, and other parts of the body.
