    A Glossary of Heart Disease Terms

    Commissurotomy: A surgical or catheter procedure that helps to repair the damage caused by defective heart valves. In some patients, specifically those with rheumatic heart disease, this area of the heart (also called the commissures) can become scarred and the valve leaflets fail to open and allow blood to flow through easily. In this surgery, the commissures can be released or reopened.

    Complex Carbohydrates: Starchy foods that are good sources of energy and nutrients, such as whole grain breads, rice, and pasta.

    Congenital Heart Defects: Heart defects present at birth.

    Congestive Heart Failure (CHF or heart failure): A condition where the heart muscle weakens and can't pump blood efficiently throughout the body.

    Constrictive Pericarditis: The pericardium is the sac around the heart. In people with constrictive pericarditis, this sac becomes inflamed and scarred leading to shrinkage of the pericardium. This can prevent the heart from filling to its full extent.

    Coronary Arteries: Network of blood vessels that branch off the aorta to supply the heart muscle with oxygen-rich blood. There are two main coronary arteries: the right and the left. The left splits into two arteries called the circumflex and the left anterior descending (LAD) arteries, thus, the heart is often considered to have three major coronary arteries.

    Coronary Artery Disease (atherosclerosis): A build-up of fatty material in the wall of the coronary artery that causes narrowing of the artery.

    Coronary Spasm: Repeated contractions and dilations of the coronary arteries, causing a lack of blood supply to the heart muscle. It may occur at rest and can even occur in people without significant coronary artery disease.

    Cyanosis: A blue tint to the skin, indicating the body is not receiving enough oxygen-rich blood.

    Defibrillator: A machine that is used to administer an electric shock to the heart in order to re-establish normal heart rhythm.

    Diabetes: A condition in which the body does not produce or respond to insulin (a hormone produced by your body, which allows blood sugar or glucose into your body's cells for energy).

    Diastolic Blood Pressure: The pressure of the blood in the arteries when the heart is filling. It is the lower of two blood pressure measurements (for example, 120/80, where 80 is the diastolic pressure).
