[|Human|] my mother is having pain in chest from almost past one week now, we consulted cardiologist & after ECHO test he suggested that one of the artery has only 19% blood supply to heart, she is diabetic also. is angioplasty required now. Please note that her blood cholesterol is absolutely normal from almost past one year.
[|AI|]  HelloWelcome to Chat Doctor. I have gone through your description. A 2D echo cannot show blockages in the heart arteries. It can show if some walls of the heart chambers are weak following a heart attack. Depending on which wall is affected, the artery which is blocked can be estimated. But the severity of blockage cannot be estimated by a 2 D echo. A 2d echo can give you the pumping function of the heart, which normally is 55-60%. Only an angiography can quantify the blockage severity. So if she has undergone an angiography then it may mean there is 81% of block and 19% of artery is functioning. If she has not undergone angiography then this 19% can be the pumping function of the heart (by 2d echo) which is low. So if angiography is not done then you must go ahead with an angiography to evaluate severity of blockages in the heart. Further, decision regarding angioplasty can be done on basis of results of angiography. If angiography is done already and the blockage is greater than 70% severity., then angioplasty must be done. Wishing her good health. Regards
