Soo one week prior to ur hear attack u were having loose stool,vomitting. How old are you? Ada hypertension,diabetes ke,high cholesterol ke? Adaa org check ur bp ke? Sebab even if you go check dr one week.prior to ur hear attack, symptoms were unspecific .even if u do ecg, not necessary there will be any changes unless u buat angiogram nmpklah block tu.
