hi,thanks for query.The presentation of heart attack
is very wide.The classical complaints from patients are chest pain
on lt.side,pain in lt.shoulder,discomfort in chest,heaviness,perspiration,vomiting or nausea.Apart from this in case of diabetics this classical complaints may not be there.The golden rule is if you are having risk factors like hypertension
,obesity,family history,diabetes,high cholesterol
,sedentary life style etc,any unusual symptoms or discomfort must be reported to doctor.
wishing you good health.
