What are our next options? Pls help!

My Fiance fainted couple of times last year.ECG and Echo was normal.But ambulatory test showed that he had borderline hypertension.Though he was given meds for high BP,he didnt take them fearing to take meds for rest of life.This year,he was depressed bcos of personal reasons,the docs told he had anxiety neurosis and gave meds for treating his insomnia/weight loss.They were of no use and he started complaining of frequent chest pains(esp when he gets stressed emotionally).ECG results shows he had a anteroseptal myocardial infarction in the past.But echo showed normal heart functioning.Also treadmill test results were normal.USG abdomen,renal doppler,complete blood panel were normal.Docs frm 2 reputed hospitals told not to worry and to take high bp meds regularly.He is taking BP meds last 1.5 months.Still he complains of frequent chest pain(sometimes severe) whenever he gets too emotional(angry/crying) which lasts 3-6 days.Also coughs during that episode are painful.I am scared.pls help
