A 50 year old man with a history of smoking, hypeension, and chronic exeional angina develops several daily episodes of chest pain at rest compatible with cardiac ischemia. The patient is hospitalized. All the following would be pa of an appropriate management plan except –
**Core Concept**
The patient's presentation is consistent with **unstable angina**, a condition characterized by a sudden increase in frequency, severity, or duration of **angina pectoris**, often occurring at rest. This condition is a medical emergency requiring prompt intervention to prevent further **cardiac ischemia** and potential **myocardial infarction**. The management plan should focus on reducing cardiac workload, preventing further ischemia, and addressing underlying risk factors.
**Why the Correct Answer is Right**
Given the context, the correct answer would typically involve a choice that does not align with standard management strategies for unstable angina, such as **antiplatelet therapy**, **nitrates**, **beta-blockers**, and possibly **invasive coronary angiography**. However, without the specific options provided, we can infer that an inappropriate management plan might include actions that increase cardiac workload or do not address the underlying causes of ischemia.
**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it involved withholding standard therapies like **aspirin** or **clopidogrel**.
**Option B:** Might be incorrect if it suggested using **vasoconstrictors**, which could worsen ischemia.
**Option C:** Could be incorrect if it recommended **discontinuing beta-blockers**, which are crucial in reducing cardiac workload.
**Option D:** Might be incorrect if it advised against **urgent coronary angiography** in appropriate cases.
**Clinical Pearl / High-Yield Fact**
A key point in managing unstable angina is the early initiation of **dual antiplatelet therapy** (e.g., aspirin and a P2Y12 inhibitor) and **beta-blockade** to reduce myocardial oxygen demand and prevent further ischemic events.
**Correct Answer:** D. Discontinuing beta-blockers.
