Superior Vena Cava Vein the returns blood to the heart from the upper extremities and head
Ventricle The lower chambers of the hear. The pumping chambers
Venule A small vein
Infarct A localized area of tissue/muscle the is dying or dead as a result of oxygen deprivation
Artery Vessel that carries blood away from the heart
Atrium The upper chambers of the heart that receive/collect blood
Capillary Tiny blood vessels, the exchange of food, oxygen and other substances
Congentital To be born with
The pathway of the blood through the heart and body Superior and In Vena Cava, Right atrium, tricuspid valve, right ventricle,pulmonary artery, lungs the pulmonary vein, Left atrium, mitral valve, left ventricle, aorta, arteries, arterioles, capillaries, venules, veins
Myocardium The heart muscle
Pericardium outer membrane of the heart
Endocardium Inner lining of the heart
Function of the blood carries food, hormones and other substances to the cells
Vessels transportation system
Heart Pumps
Bone Marrow Where the blood cells are formed
NonPreventable Risk Factors for heart disease Age (Increases with age), gender (men greater risk), Race (African American), family history
Preventable Risk Factors for heart disease Decreased activity, high sodium, fat diet, how re react to/control stress, smoking, alcohol consumption,caffeine intake
The risks of Coronary Artery Disease Heart attack, angina
What is the treatment for angina Rest and nitroglycerin
What are symptoms of angina Pain that can be described a burning, crushing/ Located in the chest, jaw, neck, arms, substernal, back
Myocardial Infarction A heart attack, Damage to the hear muscle due to a lack of oxygen to the muscle. The amount of damage is dependent on the amount of time the muscle is without oxygen as well as the area of the heart that is deprived of oxygen
What are symptoms of Congestive Heart Disease Edema, dyspnea, rapid or irregular heart beat, pale, weak, decreased appetite
Your patient has heart disease, what would the CNA expect to see on the person's care plan Daily weights, intake and output, AAROM, pace activities to avoid over exertion, sodium restricted diets, fall prevention ,

Cardiac Rehab consists of two phases Supervised exercise and education
The normal adult pulse range 60-100
Heart rate forbradycardia Below 60
Heart rate for tachycardia Over 100
The Silent Killer Hypertension. People may not know they have hypertension until death or possible discovery of damage to body
How does untreated hypertension affect the body systems? The person could have a stoke, heart attack, heart failure, kidney failure, blindness. Any of the bodies organs may be damages
What happens to the arteries of the heart when a person has coronary artery disesase The arteries become hardened and narrow
Atherosclerosis Fatty deposits in the blood vessels
The goals of treatment for coronary artery disease Relieve symptoms, slow or stop atherosclerosis, decrease risk of blood clots, widen or bypass clogged arteries, reduce cardiac events
Heart Murmur The heart valves do not close completely. This allow blood to flow back into chambers of the heart/lungs
Aneurysm A weakened arterial wall
