Chest Pain Could Mean Aortic Valve Disease
Chest pain can mean a lot of things. You might feel a throbbing tightness after running outside in cold weather, or a deep stinging after eating too much fried food. But chest pain isn’t always related to the weather or heartburn—in some cases, it can be a sign of something more serious, like aortic valve disease.
Your heart works hard every minute of the day, pumping your blood at just the right rate to help you function properly, whether you’re watching television or running a marathon. But just as the various parts of a mechanical pump can break down or get clogged up, so can parts of your heart, including the valves that control how your blood flows through your heart’s chambers.
The human heart has four chambers. Each chamber has a valve to control how much blood goes from one to the next and to prevent blood from flowing back into the previous chamber. The aortic valve controls your blood flow as it moves from the fourth chamber—the left ventricle, into the aorta—your body’s main artery. That valve can develop two problems: aortic valve stenosis and aortic valve regurgitation.
Aortic Valve Stenosis
In medical terms, when there is stenosis, there is narrowing. So aortic valve stenosis means the blood pathway through the aortic valve has narrowed, causing an obstruction. It is the most common heart valve problem in North America.
When the valve is blocked, it can cause a cascade of problems. The left ventricle must work harder to push the blood out through the aortic valve. Over time, the muscles may become thicker and less effective. If the heart can’t work hard enough to get the blood through the valve, the blood can begin to back up and accumulate in the chamber. This can cause your blood pressure to rise. And, if not enough blood is getting through to the aorta, the tissues in your body won’t be able to get the oxygen and nutrients they need to function properly.
Aortic Valve Regurgitation
With aortic valve regurgitation, your aortic valve doesn’t close properly after the heart has pumped blood from the chamber to the aorta. This allows some blood to flow backward, in the wrong direction. In other words, it’s a leaky valve. If you have regurgitation, your heart has to pump harder to get the blood out where it is supposed to be. It can come on gradually over a long period, or it can start suddenly, depending on the cause.
Causes of Aortic Valve Disease
You can be born with aortic valve disease or regurgitation, or it can develop over time. If you are born with aortic valve disease, it’s called a congenital heart defect. But most people develop aortic valve disease later in life. Although aortic stenosis can affect anyone at any age, age-related aortic valve stenosis often affects people 60 years of age or older. Symptoms may not begin to show for another 10 to 20 years, though. It’s most often caused by:
A buildup of calcium in the valve
Scarring in the valve
Valve disease can also be caused by radiation to the chest, like radiation prescribed to treat cancer, as well as by autoimmune diseases, diet medicines (fenfluramine and phentermine), and other infections.
Symptoms of Aortic Valve Disease
Many people who have aortic valve stenosis or regurgitation don’t know it because they don’t have symptoms or the symptoms are very subtle. It is only when your heart starts to have trouble keeping up with the demand that symptoms become more noticeable.
