Dear patient the history that you give here points to a classic embolic stroke known as TIA. YOU should go to the ER immediately and tell them to get you an MRI/CT head. Mri will be better but if it takes time a ct will also point to a tia. Excellent Blood pressure may rule out a haemorrhagic stroke but it does not rule out the possibility of an embolic stroke which is common in patients with a history of a previous heart attack. I suggest you review the medications with your doctor and consider adding clopidpgrel 300mg with the aspirin you probably are taking.
