Hi,

Weakening of muscles of heart could be because of lots of causes like:

1) Blockage in the arteries of heart
2) After viral illnesses
3) Some connective tissue disorders
4) Diabetes
5) Chronic Kidney disease
6) Cause not known (idiopathic) which is one of the most common causes

So 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,
Dr Sameer Maheshwari
