Term
Definition
anemia   condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues.  
🗑
iron deficiency anemia   lack of red blood cells caused by insufficient iron which is necessary for the body to make red blood cells.  
🗑
aplastic anemia   a condition in which the bone marrow does not produce enough red blood cells.  
🗑
blood loss anemia   when excessive bleeding results in loss of more red blood cells than are created  
🗑
aneurysm   the ballooning out of the wall of an artery, often associated with atherosclerosis and hypertension  
🗑
cerebral aneurysm   a weak or thin spot on an artery in the brain that balloons or bulges out and fills with blood.  
🗑
thoracic aortic aneurysm   a weakened area in the upper part of the aorta  
🗑
abdominal aortic aneurysm   a bulge or swelling in the lower part of the aorta at the level of the abdomen  
🗑
angina   a heart condition that causes severe chest pain that radiates down the inner surface fo the left arm.  
🗑
cardiac arrest   the complete and sudden cessation of heart action  
🗑
arrhythmia   a term used to identify any abnormal changes in the heart rhythm  
🗑
arteriosclerosis   the hardening of the arteries and arterioles due to a gradual replacement of muscular and elastic tissue with fibrous and calcified tissue  
🗑
atherosclerosis   characterized by the deposit of fatty material along the linings of the arteries  
🗑
athletic heart syndrome   a series of cardiac changes resulting from strenuous exercise  
🗑
carditis   inflammation of the heart; usually used with one of three prefixes that define the portion of the heart that is involved  
🗑
pericarditis   inflammation of the pericardium, the fibroserous tissue sac that covers the heart  
🗑
myocarditis   inflammation of the myocardium, the muscle layer of the heart  
🗑
endocarditis   inflammation of the endocardial lining, heart valves, tissue adjoining artificial valves or blood vessel linings  
🗑
cerebrovascular accident   a stroke; the sudden impairment of the flow of blood to the brain  
🗑
congestive heart failure   a group of cardiac dysfunction resulting from poor performance of the heart with related congestion of the circulatory system  
🗑
left-sided heart failure   when the left ventricle of the heart no longer pumps enough blood around the body resulting in blood building up in the pulmonary veins.  
🗑
right-sided heart failure   when the right side of the heart no longer pumps enough blood to the lung; also called "cor pulmonale" or pulmonary heart disease  
🗑
coronary artery disease   disease of the arteries within the myocardium that surround the heart, who are responsible for carrying oxygen and nutrients.  
🗑
embolism   foreign matter that enters and circulates in the bloodstream  
🗑
heart failure   a condition in which the heart pumps too weakly to supply the body with blood; prevalent among the older population  
🗑
hypertension   blood pressure remains consistently elevated above 140-90  
🗑
hypertrophic cardiomyopathy   a disease in which the walls of the ventricles of the heart are markedly thickened, sometimes three times their normal width, impeding  
🗑
hypotension   blood pressure below the normal range  
🗑
leukemia   a form of blood cancer in which white blood cells may become malignant and multiply inside the bone marrow or lymphatic tissue  
🗑
murmur   abnormal sound of blood flowing through a heart valve that can be heard with a stethoscope  
🗑
myocardial infarction   a complication of a coronary artery disease that results from occlusion of an artery causing tissue death  
🗑
phlebitis   localized inflammation of a vein causing an alteration in the epithelial lining, which predisposes to the formation of a thrombus  
🗑
sickle cell anemia   a genetic condition causing red blood cells to change shape and become sticky, stiff and to potentially obstruct blood flow resulting in clots and cell death.  
🗑
stasis ulcer   a secondary condition resulting from chronic venous insufficiency  
🗑
thrombophlebitis   an acute condition in which the lining of the vein wall becomes inflamed and a thrombus forms  
🗑
varicosities   veins that become dilated, twisted and inefficient resulting from weakness of the valves in the saphenous vein and its branches  
🗑
