Angina is chest pain or discomfort that occurs when your heart doesn't get as much blood and oxygen as it needs. In angina, the need for increased blood flow isn't met for a short time. When increased demand for blood goes away, angina symptoms go away too. While the pain of angina may come and go, it's a sign of heart disease and can be treated. Lifestyle changes, medications, medical procedures and surgery can help reduce angina. © AHA
Coronary arteries are the blood vessels that feed your heart muscle. If the arteries harden and narrow, your heart muscle can't get the blood it needs to work well. Coronary heart disease can lead to a heart attack. It is the leading cause of death for men and women in the United States.
These are clumps of blood that form when blood cells stick together. Some types of clots are helpful. For example, when you're cut, your blood forms a clot to seal the wound. But sometimes, blood clots can form inside your arteries or veins for other reasons. They can clog your blood vessels. This can be life-threatening.
Two large blood vessels, known as the "carotid arteries," travel from your aorta up through your neck. There's one on each side of your neck. They carry blood to your head and brain. In some people, these arteries become narrowed over time by a waxy buildup called "plaque." When this happens, we say you have "carotid artery disease." This disease restricts blood flow. And it can lead to serious health problems.
This is a narrowing of the heart's aortic valve. That's the valve that opens to the aorta (the main vessel that carries blood from the heart to the body). With stenosis, the valve doesn't fully open. That makes it hard for your heart to pump enough blood out to your body.
If you have a heart murmur, you may be wondering what it means. Your physician may have told you that it was an "innocent murmur" or you may have been referred for further tests. This American Heart Association video explains the causes of heart murmurs and what you may need to know about your heart health.
Deep vein thrombosis is a type of blood clot that can develop when you sit still for long periods. It can also be caused by certain medical conditions that make the blood clot more easily. You can take precautions to reduce your risk for developing this dangerous condition.
When you spend long periods of time in a hospital bed, you may be at risk for developing deep vein thrombosis. This is a type of blood clot that forms in a vein, usually in the legs. You may be prone to developing this type of clot because of a blood clotting disorder or other condition. But these clots are also caused by lack of movement. If you keep your legs in the same position for long periods of time, you raise your risk for a clot. Fortunately, you can take some simple precautions to keep a clot from forming.
This condition, commonly called "VTE," occurs when a blood clot forms in a vein deep within your body. This can happen in your leg, or in another part of your body. The clot travels through your circulatory system. When it reaches your lungs, it blocks an artery within them. This prevents oxygenation of your blood. This is a pulmonary embolism. It can be fatal.
Venous thromboembolism (VTE) is a blood clot that starts in a vein. VTEs affect up to 600,000 people in the United States each year. There are two types: • Deep vein thrombosis (DVT) — A clot in a deep vein, usually in the leg, but sometimes in the arm or other veins. • Pulmonary embolism (PE) — When a DVT clot breaks free from a vein wall, travels to the lungs and blocks some or all of the blood supply.
Spending long hours in a bed or a chair can increase your risk for venous thromboembolism, commonly called "VTE." This is a type of blood clot that can form in a vein in your leg and then travel to your lungs. It can be fatal. It's important to follow the advice of your healthcare provider so you can prevent this dangerous condition.
In the days and weeks after surgery, you have a higher chance of developing a deep vein thrombosis (DVT). This is a condition in which a blood clot or thrombus develops in a deep vein. They are most common in the leg. But, a DVT may develop in an arm, or another deep vein in the body.
Vena cava filter implantation is a procedure to place a device in the inferior vena cava. The inferior vena cava is the large vein that returns blood from the lower body to the heart. The device is a filter that traps blood clots in the lower body. This prevents the clots from traveling to the lungs.
A deep vein thrombosis (DVT) is a blood clot in a large vein deep in a leg, arm, or elsewhere in the body. The clot can separate from the vein, travel to the lungs and cut off blood flow. This is a pulmonary embolism (PE). Pulmonary embolism is very serious and may cause death.
The aorta is your body's main artery. It carries blood down along the front of your spine to the parts of your body below your heart. If the wall of your aorta in your abdomen weakens and balloons outward, you have an abdominal aortic aneurysm. It's a serious condition, and one that often has no warning signs.
This common heart problem is present at birth. It's a hole in the wall between the heart's two lower chambers. These chambers are called the "ventricles," and the wall between them is called the "septum." The hole lets oxygen-rich blood flow back to the lungs, instead of out to the body where it's needed.
This procedure is usually performed in the first year of a child's life to repair a ventricular septal defect (VSD). Sometimes called a hole in the heart, this defect occurs in the wall between the heart's two ventricular chambers, creating abnormal blood flow. The surgery closes the hole with a patch.
This is an abnormal connection between blood vessels. It happens when arteries connect directly to veins without first sending blood through tiny capillaries. An AVM can look like a tangle of blood vessels. They form anywhere in your body, but most often they form in or around the brain and along the spinal cord.
Coronary microvascular disease (MVD) is heart disease that affects the walls and inner lining of tiny coronary artery blood vessels that branch off from the larger coronary arteries. Other names for coronary MVD are small artery disease, small vessel disease, cardiac syndrome X and nonobstructive coronary heart disease. © AHA
This is a problem with the heart's mitral valve. That's the valve between the chambers on the left side of the heart. The mitral valve opens when the heart expands, and closes when the heart contracts. But with this condition, one or both of the valve's flaps are floppy or stretchy. They don't close the way they should. Instead, they bulge into the upper chamber. Blood may leak through the valve.
This is a tear in the wall of your aorta. Your aorta is the large blood vessel that carries blood from your heart to the rest of your body. The wall of the aorta is made of three layers. An aortic dissection is a tear in the aorta's inner wall. Blood flows through the tear and separates the aorta's inner and middle layers. Blood that normally flows to other parts of your body fills this space, forming a bulge.
This is a rare and serious heart issue that can affect young, healthy people. It's triggered by a sudden, blunt impact to the chest. If this happens at just the right time during the heartbeat cycle (and in just the right place on the lower left side of the heart), it affects the heart's electrical signals. These are the signals that control the heartbeat. With commotio cordis, the heart muscle begins to flutter. The person's blood stops circulating properly. They lose consciousness. We call this "cardiac arrest." Without fast medical help, they will die.
Infective Endocarditis is an infection of the lining of the heart and/or of the heart valves. It happens when bacteria (germs) enter the bloodstream (bacteremia) and go to the heart. The germs then cause infection in the heart. The germs can enter your bloodstream in a number of ways. It may happen during a dental procedure. It can happen through a cut. Or the germs can come from an infection elsewhere in the body.
With the heart condition TCM, blood flow to part of the heart is briefly blocked. This might happen if the coronary arteries have a temporary spasm. It might also occur if the smaller blood vessels of the heart don't get enough blood. Although the symptoms of TCM may feel like a heart attack, the 2 conditions are different.
