Cardiac index: A cardiodynamic measure based on the cardiac output, which is the amount of blood the left ventricle ejects into the systemic circulation in one minute, measured in liters per minute (l/min). Cardiac output is indexed to a patient’s body size by dividing by the body surface area to yield the cardiac index.
- Cardiac myocyte
Cardiac myocyte: A heart muscle cell. Sometimes called a myocyte when it is understood that it is in the heart. See also: Myocyte.
- Cardiac muscle
Cardiac muscle: A type of muscle tissue that is found only in the heart and is distinguishable from the two other forms of muscle, smooth muscle (that moves internal organs, such as the bowels, and vessels, such as the artery walls) and skeletal muscle (that powers joints). Cardiac muscle is responsible for pumping blood throughout […]
- Cardiac myxoma
Cardiac myxoma: A benign tumor of the heart and the most common type of heart tumor in adults. Cardiac myxomas can appear in an isolated case or in families, sometimes as part of an hereditary syndrome called the Carney complex. Some families have the Carney complex variant as well as the trismus-pseudocamptodactyly syndrome (Hecht syndrome). […]
- Cardiac output
Cardiac output: The amount of blood the heart pumps through the circulatory system in a minute. The amount of blood put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume and the heart rate determine the cardiac output. A normal adult has a cardiac output […]
- Cardiac rehabilitation
Cardiac rehabilitation: A program for people with heart disease designed to reduce future heart risks. Cardiac rehabilitation usually consists of nutritional counseling; management of lipid levels, hypertension, weight, and diabetes; smoking cessation; psychosocial interventions; physical activity counseling; and exercise training. Cardiac rehabilitation reduces the risks of subsequent heart attacks and death from other causes. Cardiac […]
