70 yo male, play ice hockey 5 times a week for the last 15 years, and several times a week for the last 40 years. Syncope event app. hour after hockey in December 2016, nothing much found. Went on 80 mg Lipitor.
April 2017, pre-syncope event while changing after playing hockey. Head in lap, and resolved. Had cardiac cath the next week. No blockages of concern; one of 30% in “center” part(?) of heart. DID find a myocardial bridge on the left descending artery. Through all of this, normal blood and EKG’s, nothing on head CT scan. Never any chest pains while exercising or not. Bridge is clear of any block, but compresses up to 80% during heart pumping. Cardiologist says I’m fine, take 40 mg of Lipitor daily. Resume all activities, and go back to see him in 6 months. Says if I feel another event coming on, to get my feet up so blood goes to my head.
My question: Is the myocardial block the direct reason for the syncope symptoms, or is it likely there may be something else going on?
