What is a common complication of myocardial infarction?

A common complication of myocardial infarction is the occurrence of arrhythmias. After a heart attack, the myocardium can become damaged and the electrical conduction system of the heart may be disrupted. This disruption can lead to various types of arrhythmias, including tachycardia, bradycardia, and potentially life-threatening ventricular fibrillation. The ischemic state of the heart tissue alters the normal ion flow and electrical stability, making arrhythmias a significant risk in the post-infarction period.

While the other options—heart murmurs, hypotension, and stroke—can also be associated with myocardial infarction, they are not as direct and common as arrhythmias. Heart murmurs may develop due to complications such as valve dysfunction, but they are not as universally expected. Hypotension can occur due to cardiogenic shock or extensive heart damage, and while it's serious, it is not as frequently encountered immediately following a myocardial infarction. Stroke can also be a risk, particularly in cases where atrial fibrillation occurs due to the arrhythmias, but it is less direct compared to the immediate likelihood of experiencing arrhythmias post-MI. Understanding the mechanisms of arrhythmias helps in recognizing their prevalence in the context of myocardial
