The way Viagra works, is to better the stream of blood that circulates around the body by making grow the level of a protein known as phosphodiesterase 5 that is located in the phallus and constricts the arteries in that area. However, this protein is also located in two other zones of the human body, the lungs and the right ventricle of the heart. Pulmonary hypertension affects the stream of blood to the lungs, therefore restricting the arteries and stretching the right ventricle of the heart. It is similar in diagnosis to blood hypertension, but the additional exercise the heart must do to pump the protein around the body in the blood often leads to weariness, dyspnea and in extreme cases can cause death of the patient. Having blood hypertension is easily controlled, and with the corresponding treatment patients can increment their lifespan by more or less 20 years. However, if a patient suffers from pulmonary hypertension, their life is significantly decreased. In the most serious of cases, a patient may only have three years without the correct medicine, and this has a damaging effect on their quality of life. No real testing was executed with this medical condition, as it was difficult to determine. Then, in 2002 experiment was executed on a number of patients who sufered from this condition. PreviousPreceding tests with other treatment was focused on healthy hearts, and did not reach successful results because it was difficult to strengthen the correct ventricle combining with reducing blood pressure and relaxing the lungs. This study involved giving patients controlled doses of Viagra, and lead to surprising results. Viagra was seen to be highly successful in enhancing the heart function of patients who have a diseased right ventricle, and decreased the hypertension in their lungs. Because Viagra is a completely safe and plain drug that works with the chemical imbalances in the blood stream, doctors at Glasgow’s Yorkhill Children’s Hospital prescribed this treatment to children who suffered from extreme pulmonary hypertension. The outcome was astonishing. Many of these babies would not have made it without this interference of Viagra, and the therapy has resulted in a breakthrough with improving 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 popular and successful therapy in conditions such as erectile dysfunction, and now was proved a success in treating pulmonary hypertension. Widening the blood vessels and easing the breathing troubles of the patient is a modern breakthrough. Because Viagra has no notable side effects, it can now be given to many patients of all ages who suffer from various blood related illnesses.
