Mild regurgitation is not considered medically significant and should not be an issue going forward...Many individuals have lived a lifetime without any progression or symptoms and should not be considered an employment problem.
Mild pulmonary hypertension is the result of respiratory problems and the underlying cause can be the pulmonary artery that goes to the lungs or the lungs itself....usually due to blood clots or lung disease that presents a higher than normal resistance the right side of the heart pumps against. There is no cure but treatment for any symptoms can be effective. The goal of treatment is to control symptoms. It is important to treat medical disorders that cause pulmonary hypertension, such as lung conditions, and heart valve disorders.
Pre-hypertension refers to systemic blood pressure and normal is 120 systolic and 80 for diastolic. Pre-hypertension is no greater than 130/90, but most doctors now take the position that anything over 120/80 is high and no longer accept the opinion that 130/90 is not high blood pressure and should be treated.
