Metabolic syndrome is the name for a group of risk factors that raises your risk for heart disease and other health problems, such as diabetes and stroke. The term "metabolic" refers to the biochemical processes involved in the body's normal functioning.

Peripheral artery disease is more common in blacks than any other racial or ethnic group. The major risk factors for peripheral artery disease include smoking, older age, and diseases and conditions such as diabetes, high blood pressure, high blood cholesterol, coronary heart disease, stroke, and metabolic syndrome.

The most common cause of high blood cholesterol is an unhealthy lifestyle. However, the genes that you inherit from your parents, other medical conditions, and some medicines may also cause high blood cholesterol.

Common sleep apnea signs and symptoms are snoring or gasping during sleep; reduced or absent breathing, called apnea events; and sleepiness. Undiagnosed or untreated sleep apnea prevents restful sleep and can cause complications that may affect many parts of your body.

The major types of stroke are ischemic (when an artery to the brain becomes blocked) and hemorrhagic (when an artery in the brain leaks blood or breaks open).

After CABG surgery, you will need time to recover. There are also potential complications from surgery, including arrhythmia, heart attack, and infection.

Your doctor may diagnose angina based on your medical history, a physical exam, and diagnostic tests and procedures. These tests can help assess whether you need immediate treatment for a heart attack. Some of these tests may help rule out other conditions.

Cardiac catheterization takes place in a catheterization laboratory, or cath lab, which is similar to a small operating room. A long thin tube called a catheter is inserted via a needle, guidewire, and sheath into a blood vessel leading to the heart.

There are many types of conduction disorders that can occur anywhere along the cardiac conduction system: at the sinoatrial (SA) node, the atrioventricular (AV) node, or the bundle branches. The problem can be with signal generation, how the signal travels through the heart, or both. Disorders can occur on a much smaller level within ion channels in a heart muscle cell that work together to make the heart cell contract.

Cystic fibrosis is an inherited disease caused by mutations in a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene.
