A patient presents with intense chest pain of 2 hrs duration ECG shows ST depression in leads I and V1 to V4. There is associated T inversion and CPK-MB is elevated. Which of the following should be included in his management
**Core Concept**
The patient's presentation is indicative of non-ST elevation myocardial infarction (NSTEMI), characterized by chest pain, ST depression, T inversion, and elevated CPK-MB levels. The management of NSTEMI involves a combination of antiplatelet therapy, anticoagulation, and vasodilation to reduce ischemia and prevent further cardiac events.
**Why the Correct Answer is Right**
The inclusion of nitroglycerine, aspirin, and metoprolol in the management of NSTEMI is based on the pathophysiology of the condition. Nitroglycerine (A) helps to reduce myocardial oxygen demand by vasodilating coronary arteries and decreasing ventricular preload. Aspirin (B) exerts its antiplatelet effect by inhibiting the enzyme cyclooxygenase-1 (COX-1), which is essential for platelet aggregation. IV metoprolol (C) reduces heart rate and myocardial contractility, thereby decreasing myocardial oxygen demand. The combination of these therapies helps to stabilize the patient and prevent further ischemic complications.
**Why Each Wrong Option is Incorrect**
**Option A:** While nitroglycerine is essential in the management of NSTEMI, it is not the only correct option. However, in a scenario where the patient is hypotensive or has signs of cardiogenic shock, nitroglycerine might not be the best initial choice.
**Option B:** Although aspirin is a crucial component of NSTEMI management, it is not the only correct answer. However, it's worth noting that aspirin should be given as soon as possible in the management of acute coronary syndromes.
**Option C:** IV metoprolol is a correct choice in the management of NSTEMI, but it's not the only correct answer. However, it's essential to note that beta-blockers like metoprolol should be used with caution in patients with heart failure or severe bradycardia.
**Clinical Pearl / High-Yield Fact**
In the management of NSTEMI, it's essential to remember that the goal is to reduce ischemia and prevent further cardiac events. The combination of antiplatelet therapy, anticoagulation, and vasodilation helps to achieve this goal.
**Correct Answer Line**
✓ Correct Answer: D. All of the above.
