Term
|
Definition
| a localized area of ischemic necrosis in an organ or tissue resulting from sudden reduction of either its arterial supply or venous drainage |
|
|
Term
| General morphology of infarcted organs |
|
Definition
| classified on basis of color (reflecting amount of hemorrhage) and the presence or absence of microbial infection: Red or White, Septic or Bland |
|
|
Term
|
Definition
| occur with venous occlusions, loose tissues, tissues with duel circulation, previously congested tissues, and when flow is reestablished after infarction has occurred |
|
|
Term
|
Definition
| occur with arterial occlusions in solid organs with end-arterial circulations, where tissue density limits the seepage of blood from adjoining patent vascular beds |
|
|
Term
|
Definition
| infected cardiac valve vegetations embolize, or when microbes seed necrotic tissue, infarct becomes an abscess with a greater inflammatory response |
|
|
Term
|
Definition
| absence of bacterial involvement |
|
|
Term
| Factors affecting severity of injury due to infarction |
|
Definition
| general status of the blood and the cardiovascular system, the anatomic pattern of the vascular supply of the tissue involved (single versus dual/anastomosing blood supply), the rate of development of the occlusion, the vulnerability of the tissue to ischemia. |

|
Definition
| 40% of all deaths in the US are a consequence of cardiovascular disease, with most of these deaths stemming from myocardial or cerebral infarction |
