**Core Concept**
Infective endocarditis is a serious infection of the heart valves, often caused by bacterial or fungal pathogens. The condition can lead to various complications due to the direct damage to the heart valves and the body's systemic response.

**Why the Correct Answer is Right**
Infective endocarditis can cause embolic events, such as stroke or peripheral artery occlusion, due to the release of septic emboli from the infected valve. It can also lead to heart failure, either through valve destruction or damage to the surrounding heart tissue. Additionally, infective endocarditis can cause immune-mediated complications, including glomerulonephritis and Roth's spots. However, one notable complication that is not typically associated with infective endocarditis is **Option A: Myocardial infarction**. This is because infective endocarditis does not typically cause atherosclerotic plaque formation or coronary artery disease, which are the primary underlying causes of myocardial infarction.

**Why Each Wrong Option is Incorrect**
* **Option B:** Embolic events, such as stroke or peripheral artery occlusion, are a well-known complication of infective endocarditis, making this option incorrect.
* **Option C:** Heart failure is a potential complication of infective endocarditis, either through valve destruction or damage to the surrounding heart tissue, making this option incorrect.
* **Option D:** Immune-mediated complications, such as glomerulonephritis, are a known complication of infective endocarditis, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
Remember that infective endocarditis can cause a wide range of systemic complications, including embolic events, heart failure, and immune-mediated complications. When evaluating a patient with suspected infective endocarditis, it is essential to consider these potential complications and their impact on the patient's overall clinical picture.

**Correct Answer:** A. Myocardial infarction
