Question | Answer |
---|---|
arteriosclerosis | (arterio=artery/sclerosis=hardened) the hardening of arteries with age |
atherosclerosis | lipid (cholesterol) plaque reduces blood flow |
coronary artery disease (CAD) | heart arteries clogged by plaque, clots may form |
ischemia | reduced blood flow to heart |
angina pectoris | pain caused by reduced blood flow to heart (heart pain) |
myocardial infarction (MI) | heart attack, blood flow blocked, heart muscles die |
arrhythmias | irregular heart beat, not in normal sinus rhythm / fillibration- use defillibrators to shock heart |
heart failure | heart weakens to degree that it cannot maintain adequate blood flow, several causes |
pericarditis | inflammation of pericardial membrane (itis=inflammation) |
polycythemia | high rbc count |
anemia | low rbc count- cannot transport enough oxygen |
leukemia | series of diseases of wbc's/ cancer of wbc forming cells |
hemophilia | bleeder's disease, inherited from mom to son |
sickle cell disease | abnormal hemoglobin which gives up oxygen to interstital fluid and causes the cell to sickle and rupture easily- erythropoiesis cannot keep pace with hemolysis- prolonged oxygen reduction may cause extensive tissue damage |
jaundice | yellowing of skin and eyes due to excess bilirubin in the blood |
thrombocytopenia | (penia=poverty) very low platelet count that results in a tendency to bleed from capillaries |
