Viagra

Many men worldwide take Viagra to combat a common problem called erectile dysfunction. The effects on a man’s sexual function are now widely known. However, you may not be aware that Viagra also has a positive effect on the heart. Men who took the drug revealed lower effects of hormonal stress to the heart. The results of studies conducted with mice were even more surprising; Viagra often avoided or reversed the harmful effects of chronic hypertension on the heart.
John Hopkins researchers studied the effects of Viagra on the human heart since the drug was already known to dilate genital blood vessels in order to maintain an erection. The results revealed that Viagra may be successful in treating pulmonary hypertension. Until that study, Viagra’s positive effects on the heart were unknown.
Viagra effectively dulls an increased heart beat which is caused by chemically-induced stress. The drug decreases the amount of force required to pump excessive blood from the heart to other parts of the body.
A cardiologist and author of the John Hopkins study, Dr. David Kass, and his researchers performed additional experiments on mice. These individuals discovered that Viagra can block short-term effects of hormonal stress to the heart. Viagra is also successful in preventing and even reversing long-term damage caused by chronic hypertension on the heart. The test results revealed that Viagra could reverse the negative effects of cardiac hypertrophy and heart failure on the weakened heart muscles of the mice. However, no solid evidence exists because the tests have not been conducted on human hearts. Read the rest of this entry »
