When divided by unified atomic mass units or daltons to form a pure numeric ratio, the atomic mass of an atom becomes a dimensionless value called the relative isotopic mass (see section below). Thus, the atomic mass of a carbon-12 atom is 12 u or 12 daltons (Da), but the relative isotopic mass of a carbon-12 atom is simply 12.
Most people who have mitral valve prolapse (MVP) donât need treatment because they donât have symptoms and complications. Even people who do have symptoms may not need treatment. The presence of symptoms doesnât always mean that the backflow of blood through the valve is significant. People who have MVP and troublesome mitral valve backflow may be treated with medicines, surgery, or both. The goals of treating MVP include:
They also never experience any health problems due to mitral valve prolapse. Chest pain is the most frequent symptom in people who have symptoms with mitral valve prolapse. The chest pain may be very bothersome and frightening, but it does not increase the risk of heart attack, death, or other heart problems.Mitral valve prolapse is the most common cause of mitral regurgitation.That's a condition in which some blood flows backward through the mitral valve with each heartbeat. Over years, moderate or severe mitral regurgitation can cause weakness of the heart muscle, known as congestive heart failure.hey also never experience any health problems due to mitral valve prolapse. Chest pain is the most frequent symptom in people who have symptoms with mitral valve prolapse. The chest pain may be very bothersome and frightening, but it does not increase the risk of heart attack, death, or other heart problems.
