I am suffering from severe symptoms from the last 2 months including, shortness of breath, constant chest pressure, difficulty in exertion, feeling weak. I have done with many test including ecg's, echo, ETT, all blood tests and CT coronary angiography. I didn't tolerate ETT and CT coronary angiography shows a soft plague and the junction of proximal to mid LAD causing mild stenosis, rest of all the tests are normal. I am taking concor 1.25mg, rovista 5mg and ascard 75 from the last 1 month but
