Thanks for your question on Health Care Magic.
I can understand your concern.
Since you have gained weight and having slight ST
depression in recent ecg (which was not present in previous ecg s), better to rule out heart diseases for your pain.
So get done
1. Blood pressure monitoring
2.
Stress test 3. 2d echo
4. Holter monitoring (24 hour continuous monitoring of ecg).
If all these are normal than no need to worry for heart diseases.
Sometimes stress and
anxiety can cause similar symptoms.
So avoid stress and tension, be relax and calm.
Don't worry, you will be alright.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
