Infarction & Embolism Flashcards
An area of ischaemic necrosis within a tissue/organ is produced by occlusion arterial supply/venous drainage.
Infarct.
Define embolism.
The lodging of an embolus, a blockage-causing piece of material, inside a blood vessel.
White infarcts are when the patient is…
Anaemic.
Red infarcts are when the patient is…
Haemorrhagic.
A myocardial infarction caused by a sudden complete (100 percent) blockage of a heart artery (coronary artery), is known as…
A STEMI or ST-elevation.
A severely narrowed artery that is usually not completely blocked, is known as…
Non-STEMI.
A Transmural infarct is also known as a…
STEMI
A subendocardial infarct is also known as…
Non-STEMI.
Stenosis occurs in a non-STEMI, but what doesn’t occur?
There is no plaque rupture. No thrombosis.
Thrombi that adhere to the wall of a blood vessel are known as…
Mural Thrombi.
Give 2 complications following MI.
Cardiac rupture (mechanical weakening). Pericarditis. Mural thrombosis (lead to thromboembolism). Ventricular aneurysm.
Give 3 types of emboli.
Fragments of thrombi. Septic emboli (from infective heart valve). Air emboli. Fat globule. Material from ulcerating plaque. Fragment of tumour.
From where can a thrombi dislodge to cause a Pulmonary Embolism?
Deep vein thrombosis (DVT) - thrombi dislodged from leg. Thrombi from right side of the heart.
Give 2 symptoms of a patient with Pulmonary Embolism.
Shortness of breath. Chest pain particularly upon breathing in. Coughing up blood.
