I am fine with warfarin and have had no adverse events.

Warfarin treatment should be reconsidered, in case of frequent out of range INR measurements.

The doctor should check often the INR range. Since patient's INR seems to be not so well regulated, it would be better off with one

of the NOAC medications.

Patient preference is another reason for switching to NOAC treatment.  These drugs allow for no measurements of their

effectiveness, given they are dosed and adhered to appropriately.

This is a wrong response that could lead to potentially harmful results to the health.
