myocardial infarction

Myocardial infarction

Myocardial infarction is necrosis of myocardial tissue which occurs as a result of a deprivation of blood supply, and thus oxygen, to the heart tissue. Blockage of blood supply to the myocardium is caused by occlusion of a coronary artery.

410 grams

A normal heart weighs 300 grams (range: 270 to 360 grams).

atherosclerotic narrowing

Atherosclerosis is the deposition of lipid into the intima of arteries, resulting in narrowing of the vessel lumen.

occlusion

An occlusion is a blockage.

thrombus

A thrombus is a solid mass resulting from the aggregation of blood constituents within the vascular system.

palliative surgery

Palliative surgery provides alleviation but is not curative.

15,256 cells/cm

A normal white blood cell count is 4000-11,000 cells/cm².

infiltrates

An infiltrate is an accumulation of cells in the lung parenchyma--this is a sign of pneumonia.

consolidated

Consolidation is the filling of lung air spaces with exudate--this is a sign of pneumonia.

abscesses

An abscess is a collection of pus (white blood cells) within a cavity formed by disintegrated tissue.

In alcoholics, aspiration pneumonia is common--bacteria enter the lung via aspiration of gastric contents.
