[|Human|] i had a treadmill test last week, the dr said it showed no signs of blockage but my heart was weak sounding and i have to go get another test done, ive been feeling weak and tired, im a overweight 50 year old woman, i live alone, kinda nervous, just wondering about a heart attack with no blockage, if i should be scared to stay alone
[|AI|]  Hi, Weakening of muscles of heart could be because of lots of causes like:1) Blockage in the arteries of heart2) After viral illnesses3) Some connective tissue disorders4) Diabetes5) Chronic Kidney disease6) Cause not known (idiopathic) which is one of the most common causes it is not only blockage which can cause weak heart, there are in fact a number of causes. But we always rule out blockage in arteries of heart. In your case if you don't have blockage then you won't have a heart attack but keep taking your medicines to improve the heart function. Hope I have answered your query. Let me know if I can assist you further. Thanks, Chat Doctor.
