Hypertension is associated with the resistence of the vessels the heart pumps against. For instance, the smaller the diameter of the vessel the more resistance...diameter can be reduced by a buildup of plague and/or soft plaque that narrows (stenosis) the lumen (vessel channel). Medication that dilates the vessel reduces the resistance.
Trivial MV regurgitation does not have any symptoms and is considered medically insignificant. Not an uncommon condition and almost never progresses nor cause any symptoms. If the condition is moderate to severe one would begin to have symptoms of shortness of breath, fatigue, chest pains, etc. because the cardiac output is reduced.
Thanks for the question, and if you have any follow up questions you are welcome to post. Take care.
