**Core Concept**
The management of a patient with acute myocardial infarction (MI) who is undergoing non-emergent surgery, such as prostatectomy, requires careful consideration of the risks and benefits of anticoagulation and antiplatelet therapy. The primary concern is to prevent further thrombotic events, while minimizing the risk of bleeding complications.

**Why the Correct Answer is Right**
In this scenario, the patient's history of diabetes and hypertension increases the risk of thrombotic events. The development of MI further complicates the situation. However, the patient is scheduled for non-emergent surgery, which requires careful management of anticoagulant and antiplatelet therapy. The correct approach is to continue the patient's existing antiplatelet therapy, such as aspirin, while bridging with a parenteral anticoagulant, like unfractionated heparin (UFH) or low molecular weight heparin (LMWH), to cover the period of surgery and immediate post-operative period. This approach allows for the continuation of antiplatelet therapy while minimizing the risk of bleeding complications.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it suggests discontinuing the patient's existing antiplatelet therapy, which would increase the risk of further thrombotic events.
**Option B:** This option is incorrect because it implies the use of a single anticoagulant, such as warfarin, without bridging therapy, which would increase the risk of bleeding complications.
**Option C:** This option is incorrect because it suggests the use of a new anticoagulant, such as dabigatran, without considering the patient's renal function and potential interactions with other medications.

**Clinical Pearl / High-Yield Fact**
In patients undergoing non-emergent surgery, it is essential to continue antiplatelet therapy while bridging with a parenteral anticoagulant to minimize the risk of thrombotic events and bleeding complications.

**Correct Answer: C. Continue antiplatelet therapy with bridging anticoagulation.**
