Hello! From what you described above, it seems strongly that you have had an episode of anteroseptal wall myocardial infarction, most probably well before the attack of stroke, as you have described. Also the cause of the stroke was almost certainly due to transient thromboembolism of the cerebral arteries, the source of the thrombus being the dyskinetic myocardial portion or the atrium. You need not worry, however as this have been an old event, but must receive a lifelong prophylactic treatment with antiplatelet agents like aspirin & clopidogrel after consultation with a cardiologist. Thanks & take care of yourselves.
