For men, flagging potency levels means that every thing is not right with the cardiovascular system. Experts believe that a rush to fix the problem with impotence drugs may actually be a bigger health threat. ED is more often a manifestation of underlying problems and even precedes angina. In fact, one should consider it an early warning.

With the roaring business of all ED drugs which include Viagra, Cialis and Levitra Professional have put the research spotlight back on ED. Furthermore, studies suggest that the condition is largely physiological for most men and not psychological.

Additionally, researchers have deduced from a study that arteries of men with ED expanded less efficiently than of men without ED – which could be a possible sign of underlying heart disease.

But most men with ED are not even close to cardiovascular deterioration. For them, the problems could be the blood vessels inside the penis and the smooth muscle around them that may be affected on a biochemical level. Start feeling more confident with canadian pharmacy viagra for a really long time!

However, it has been known that erectile dysfunction is largely due to reduced nitric oxide in the endothelium, which is the inner lining of the blood vessels. During an erection the blood flow demands increase and the endothelium releases nitric oxide to help trigger blood vessel expansion. Nitric oxide is the primary chemical that aids normal erectile function and is also very important as an anti-atherosclerotic agent, which works to resist the hardening of the arteries. In this sense, ED may to a large extent, serve as an early signal that blood vessels elsewhere in the body are not expanding as they should.

Incidentally, all ED drugs help increase nitric oxide levels in the endothelium and were therefore first studied as possible treatments for cardiac problems. However, these drugs work better in some organs and don’t work well in some.

Although, statins do improve the function of the enzyme called nitric oxide synthase, that produces nitric oxide inside the blood vessels, probably that very mechanism will help get rid of ED.
