All are true about intermittent claudication except:
**Core Concept**
Intermittent claudication is a symptom of peripheral artery disease (PAD), characterized by pain in the muscles of the lower extremities, typically in the calf, thigh, or hip, which occurs during exercise and is relieved by rest. This condition results from reduced blood flow to the affected muscles, often due to atherosclerotic plaque buildup in the femoral or popliteal arteries.
**Why the Correct Answer is Right**
The correct answer is: **Intermittent claudication is a symptom of peripheral artery disease (PAD)**. This condition occurs when the muscles of the lower extremities do not receive sufficient oxygen and nutrients during exercise, leading to pain. The pain is relieved by rest, as the affected muscles are allowed to recover and receive more blood flow. The femoral and popliteal arteries are commonly affected in PAD, as they are prone to atherosclerotic plaque buildup.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because intermittent claudication is not typically associated with smoking cessation. While smoking is a major risk factor for PAD, claudication is a symptom of the disease, not a consequence of quitting smoking.
* **Option B:** This option is incorrect because intermittent claudication is not typically associated with a normal ankle-brachial index (ABI). A normal ABI indicates adequate blood flow to the lower extremities, whereas claudication is a symptom of reduced blood flow.
* **Option C:** This option is incorrect because intermittent claudication is not typically associated with a normal exercise stress test. A normal exercise stress test would indicate that the heart and lungs are functioning properly, whereas claudication is a symptom of PAD, which affects blood flow to the muscles.
**Clinical Pearl / High-Yield Fact**
A patient with intermittent claudication may benefit from supervised exercise therapy, which involves regular walking or other exercises under the guidance of a healthcare professional. This type of therapy can help improve symptoms and slow disease progression.
**Correct Answer: D.**
