The way Viagra works, is to better the flow of blood that circulates around the human body by making grow the amount of a protein known as phosphodiesterase 5 that is located in the penis and constricts the arteries in that area. But, this protein is also found in two other areas of the body, the lungs and the right ventricle of the heart. Pulmonary hypertension influences the stream of blood to the lungs, therefore constricting the arteries and stretching the right ventricle of the heart. It is similar in diagnosis to high blood pressure, but the additional exercise the heart has to do to pump the protein around the body in the blood often causes tiredness, shortness of breath and in extreme cases can bring about death of the patient. Having hypertension is easily controlled, and with the adequate medicine patients can increment their lifespan by more or less twenty years. However, if a patient has pulmonary hypertension, their life is immensely decreased. In the most serious of cases, a patient might only have three years without the right medication, and this has a hurtful result on their quality of life. No essential testing was done with this medical state, as it was hard to identify. Then, in 2002 a study was conducted on a number of patients who sufered from this state. ForegoingPrior tests with other treatment was focused on healthy hearts, and did not reach successful results because it was hard to strengthen the adequate ventricle combining with lessening blood pressure and unnerving the lungs. This study included giving patients controlled amount of Viagra, and produced surprising outcome. Viagra was proved to be extremely successful in improving the heart function of patients who have a diseased right ventricle, and reduced the hypertension in their lungs. Because Viagra is a completely secure and plain medicine that handles the chemical disbalance in the blood flow, doctors at Glasgow’s Yorkhill Children’s Hospital gave this drug to children who were suffering from extreme pulmonary hypertension. The outcome was surprising. Many of these infants would not have survived without this interference of Viagra, and the treatment has provided a breakthrough with improving patient medication. Viagra is also helpful in cases such as lung transplant surgery, where the right ventricle can often collapse if the lung is rejected. Viagra is considered one of the most popular and successful treatment in states such as erectile dysfunction, and now was proved a success in treating pulmonary hypertension. Expanding the blood vessels and easing 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 ages who suffer from different blood related illnesses.
