my mom underwent treadmill test today and she was observed to hv minor blocks, that dont require an angiogram procedure, however, her BP, cholesterol and sugar should come down to reduce risk of an attack, and that these small blocks usually cause a heart attack...this was mixed opinion leaving us all worried..she's 65 and did have a case of high bp, close to fainting and nausea and vommitting in 2007, underwent angiogram which showed no huge blocks and ever since been on clopitab, and complains of mild chest pain almost everyday....any suggestions..please
