Thanks for posting on HCM,
You must have had an anginal attack which is a more milder form of heart attack
. Angina pectoris
is a type of coronary heart diseases which could be stable or unstable. You likely have had the stable angina
pectoris. It will also be wise to rule out peptic ulcer
I suggest you get an appointment with a physician (which is no longer an emergency) so he can evaluate you completely and provide you with preventive therapy so as to prevent future attacks as recurrence is a likely possibility.
Wish you the best
