Oral Surgery
After a myocardial infarction (MI), elective dental treatment is generally deferred for at least 6 months because of the risk of reinfarction.
However, if urgent treatment such as full mouth extractions is required within 6 months, it must be done with special precautions.
Since the patient is on anticoagulant therapy, the prothrombin time (PT/INR) must be checked and controlled to reduce bleeding risk.
The safest approach is:
Hospitalize the patient for monitoring.
Control PT/INR before surgery.
Perform extractions under local anesthesia (general anesthesia carries higher cardiovascular risk).

Physiology
The rate of gastric emptying is influenced by the type and amount of food consumed. In healthy individuals, it typically takes 1-4 hours for the stomach to empty its contents into the duodenum. The rate of emptying can be slower with high-fiber or high-fat meals and faster with liquids. Factors such as gastric motility, the presence of gastric emptying hormones, and the presence of food in the intestine also play a role in this process.
