You may have an increased risk for conduction disorders because of your age, family history and genetics, medical conditions, medicines, race or ethnicity, or sex. These factors can differ by the type of conduction disorder you have.

Signs and symptoms of DIC depend on whether the condition is acute or chronic. Acute DIC is more severe and develops quickly over hours or days. Chronic DIC happens more slowly and sometimes has no signs or symptoms. Complications from DIC can occur from both the clotting that happens in the early stages of the condition and from bleeding in the later stages. Serious complications include organ damage and hemorrhage.

Your genes, or other causes such as medical conditions or medicines, can cause bleeding disorders. Sometimes a cause may not be known. Any problem that affects the function or number of clotting factors or platelets can lead to a bleeding disorder.

Signs and symptoms of RDS usually happen at birth or within the first few hours that follow. Depending on the severity of a newborn's RDS, he or she may develop bronchopulmonary dysplasia or other medical problems, such as bleeding in the brain, kidney failure, or lung complications.

Marfan syndrome is a genetic condition caused by a mutation, or change, in one of your genes, called the fibrillin-1 (FBN1) gene. The FBN1 gene makes fibrillin-1, which is a protein that forms elastic fibers within connective tissue. Fibrillin-1 also affects levels of another protein that helps control how you grow.

Many people who have conduction disorders, such as first-degree AV block, may have no obvious signs or symptoms. Others may have signs and symptoms that occur in specific situations, such as when you experience physical or emotional stress or when you sleep. Conduction disorders can lead to life-threatening arrhythmias if undiagnosed or untreated.

If you have a known family history of Marfan syndrome or physical features of the condition, your doctor may recommend screening to find the condition early. Relatives of people who have Marfan syndrome may also want to have genetic screening. There is no way to prevent Marfan syndrome.

Your doctor will diagnose peripheral artery disease based on your medical and family histories, a physical exam, and results from one or more tests: ankle-brachial index, Doppler ultrasound, treadmill test, magnetic resonance angiogram (MRA), arteriogram, and blood tests.

Treatments for carotid artery disease may include heart-healthy lifestyle changes, medicines, and medical procedures such as carotid endarterectomy and carotid artery angioplasty and stenting.

Heart valve disease occurs if one or more of your heart valves don't work well. The heart has four valves—the tricuspid, pulmonary, mitral, and aortic valves—that make sure blood flows in the right direction through your heart’s four chambers and to the rest of your body.
