Hi, My dad is a heart patient, he had endoplasty 6 years ago, since 2 monthst he has been feeling burning in chest, so he went to see heart spacilost, who did dtress ecg and said during the ecg he had 2 cardiac pain within 4 mins so and said he would need to go for bypass surgery. So yesterday he has his engograph test and then the doc said he doent have any blockage. He doesn t need surgery, so my dad is confusd if thsre is no blockage then why he had 2 cardIac pain during stress ecg and why he is still feelinbg burning in his chest.
