The way Viagra works, is to improve the flow of blood that circulates around the body by incrementing the amount of a protein known as phosphodiesterase 5 that is located in the penis and squeezes the arteries in that zone. Nevertheless, this protein is also found in two other zones of the human body, the lungs and the right ventricle of the heart. Pulmonary hypertension affects the blood run to the lungs, therefore constricting the arteries and stressing the right ventricle of the heart. It is similar in diagnosis to blood hypertension, but the extra work the heart has to do to pump the protein around the body in the blood often is the reason of tiredness, dyspnea and in extreme cases can bring about death of the patient. Having blood hypertension is easily manageable, and with the correct treatment patients can increase their lifespan by approximately twenty years. However, if a patient suffers from pulmonary hypertension, their life span is greatly shorter. In the most serious of cases, a patient might only have three years without the correct medicine, and this has a detrimental effect on their life quality. No essential testing was done with this medical state, as it was hard to identify. Then, in 2002 a study was conducted on several patients who were suffering from this condition. PreviousPrior tests with other medicine was focused on healthy hearts, and did not achieve successful results because it was hard to strengthen the right ventricle in combination with lessening blood pressure and unnerving the lungs. This experiment involved giving patients measured doses of Viagra, and produced amazing results. Viagra was seen to be very successful in enhancing the heart function of patients who have a stressed right ventricle, and reduced the high pressure in their lungs. Because Viagra is a completely secure and natural medicine that handles the chemical disbalance in the blood run, doctors at Glasgow’s Yorkhill Children’s Hospital gave this medication to babies who were suffering from severe pulmonary hypertension. The result was astonishing. Many of these babies would not have made it without this administration of Viagra, and the cure has resulted in a breakthrough with making better patient medication. Viagra is also useful in cases such as lung transplant surgery, where the right ventricle can often collapse if the lung is rejected. Viagra is thought to be one of the most famous and successful therapy in cases such as erectile dysfunction, and now was proved a success in therapy for pulmonary hypertension. Widening the blood vessels and relieving the breathing troubles of the patient is a modern outbreak. Because Viagra has no notable side effects, it can now be given to many patients of all age categories who experience different blood related medical conditions.
