8 Symptoms of Aortic Stenosis

Aortic stenosis is a heart condition that occurs when the aortic valve of the heart is narrowed, stiffened, or otherwise cannot pass blood as easily. This disorder can have a variety of serious effects because this valve is where oxygenated blood passes into the aorta. The aorta supplies the arteries that in turn supply the body and brain. When the aortic valve is compromised, your heart simply cannot pump blood out at the same rate that it did before. In addition, the work of pumping blood against a stiffened or closed valve can do damage to the left ventricle of the heart, causing an enlarged heart and other issues. Blood clots also can form on the stiffened valve, leading to strokes or cardiac arrest.

Aortic stenosis can be caused by a congenital defect, by build up on the aortic valve, or even by rheumatic fever. It is easily treated when caught early. However, it can be fatal if left untreated. It is important for people to know the signs of aortic aortic stenosis so they can get medical help before permanent damage is done. If you or a loved one notice any of the following right symptoms of aortic stenosis, it is important to get immediate medical care.

1. Fainting

Fainting, also called syncope or loss of consciousness, occurs when the brain loses blood supply for even a short period of time. This causes people to feel dizzy and suddenly pass out. Fainting can be very serious because people can injure themselves when they fall to the ground. They can also get into an accident when they lose consciousness. While there are a variety of medical problems that can cause fainting, it should always be treated as a medical emergency.

When the brain is not getting the blood and oxygen supply that it requires, it cuts back on brain activity. This means stopping all unnecessary processes, including the simple act of being conscious. While this protects the brain from injuries due to low oxygen, it is a red flag. Fainting can occur in aortic stenosis because not enough blood can be pumped past the compromised valve. This is especially true when people are being active or under stress, when the rest of the body has high oxygen demand. Fainting also can occur if a blood clot on the valve breaks lose and travels to the brain, causing a stroke. It is important to call an ambulance and have a person immediately medically evaluated if they faint.
