All of the following are signs of Cor pumonale except: September 2007
**Core Concept**
Cor pulmonale refers to the alteration of the structure and function of the right ventricle of the heart as it struggles to pump blood through the lungs that are damaged. This condition is often a result of **pulmonary hypertension**. The key principle being tested here is the understanding of the signs that differentiate cor pulmonale from other cardiac conditions.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general signs of cor pulmonale, which include **jugular venous distension**, **hepatomegaly**, **peripheral edema**, and **cyanosis**. These signs are indicative of right heart failure, which is a direct consequence of the increased resistance in the pulmonary vasculature.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, we cannot directly address why it is incorrect. However, if it were a common sign of cor pulmonale, it would be incorrect as the answer because the question asks for what is NOT a sign.
**Option B:** Similarly, without specifics, if option B represents a known consequence or sign of cor pulmonale, such as those mentioned, it would not be the correct answer to this question.
**Option C:** Again, lacking details, if option C were a recognized manifestation of cor pulmonale, it would not be the correct choice.
**Option D:** If option D were a known sign of cor pulmonale, it would also be an incorrect choice for this question.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that cor pulmonale is a condition that affects the right side of the heart, leading to signs of right-sided heart failure. Recognizing the distinction between left and right heart failure signs is crucial for diagnosis.
**Correct Answer:** Correct Answer: D.
