Thank you for your question, i do not think you have a heart pain or angina based on the history and tests you have mentioned. Only test that can make sure you do not have angina is stress tests and simplest is stress ECG. In my opinion this should have been done along with Echocardiogram. Thank you.
Thank you for your reply, stress test has warranty of 3 years which means that if stress tests is normal then risk of you having a heart attack is almost nil. In your case situation cannot change over a week.
Thank you for your reply, it can be stomach issue including stomach ulcer or stress/anxiety can also cause such symptoms.
Thank you for your reply, Yes in your case based on your history and tests things will not change in a week, so you are safe. Silent ischemia is silent it does not gives symptoms that is why it is called silent ischemia.
