Which of the following is not a feature of red infarction?
**Core Concept**
Red infarction, also known as hemorrhagic infarction, is a type of myocardial infarction characterized by the presence of blood in the infarcted area. This occurs due to the rupture of small blood vessels within the infarcted myocardium, leading to bleeding into the surrounding tissue.
**Why the Correct Answer is Right**
Red infarction is typically associated with the following features:
* The presence of blood in the infarcted area, which can be visualized on echocardiography or cardiac MRI.
* A higher mortality rate compared to white infarction.
* A larger infarct size.
* A higher incidence of complications, such as heart failure and arrhythmias.
* The presence of a "red zone" on electrocardiography, which represents the area of infarction.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a feature of red infarction.
**Option B:** This option is incorrect because it is a feature of red infarction.
**Option D:** This option is incorrect because it is a feature of red infarction.
**Clinical Pearl / High-Yield Fact**
Red infarction is often associated with a higher risk of complications, making early diagnosis and treatment crucial in managing patients with myocardial infarction. A high index of suspicion is necessary, especially in patients with a history of hypertension, diabetes, or coronary artery disease.
**Correct Answer:** C.
