Question
Complications following an acute myocardial infarction could include which of these?W. Mitral valve incompetence due to papillary muscle dysfunction.X. Arrhythmias, for example, ventricular fibrillation.Y. Cardiac tamponade due to ventricular rupture.Z. Hypotension due to contractile dysfunction.Question 10Select one:a.Only W, X, and Y are correct.b.Only W and Y are correct.c.Only X and Z are correct.d.Only Z is correct.e.All are correct.
Solution
e. All are correct.
Explanation:
W. Mitral valve incompetence due to papillary muscle dysfunction: This can occur as a result of damage to the papillary muscles during a myocardial infarction. The papillary muscles are responsible for controlling the mitral valve, and if they are damaged, the valve may not function properly, leading to mitral valve incompetence.
X. Arrhythmias, for example, ventricular fibrillation: Arrhythmias are a common complication following a myocardial infarction. The damage to the heart muscle can disrupt the normal electrical pathways in the heart, leading to abnormal heart rhythms.
Y. Cardiac tamponade due to ventricular rupture: This is a serious complication that can occur if the wall of the ventricle ruptures following a myocardial infarction. This can lead to blood filling the pericardial sac, causing cardiac tamponade.
Z. Hypotension due to contractile dysfunction: Damage to the heart muscle during a myocardial infarction can lead to a decrease in the heart's ability to pump blood, leading to hypotension.
