Question
If the following stages in the aetiology, pathogenesis, healing and possible complications of a myocardial infarct were put in order, which would be 4th?Question 56Select one:a.Myocardial Infarction (necrosis)b.Generation of mature scar tissue.c.Myocardial Ischemiad.Thrombus formation within the left ventricle of the heart (due to stasis and collagen exposure).e.Large thrombus forming on top of an ulcerated atheroma within a coronary artery.
Solution
The fourth step in the sequence of events leading to a myocardial infarction and its aftermath would be "Myocardial Infarction (necrosis)". Here's the sequence:
-
Large thrombus forming on top of an ulcerated atheroma within a coronary artery: This is the initial event where a blood clot forms on a damaged area within the artery.
-
Myocardial Ischemia: The blood clot blocks the blood flow, causing a shortage of oxygen and nutrients to the heart muscle, leading to ischemia.
-
Thrombus formation within the left ventricle of the heart (due to stasis and collagen exposure): The ischemia can lead to conditions that promote further clot formation within the heart itself.
-
Myocardial Infarction (necrosis): The prolonged ischemia leads to the death of heart muscle cells, which is the actual heart attack or myocardial infarction.
-
Generation of mature scar tissue: After the heart attack, the body tries to heal the damaged area by forming scar tissue.
