I am a cardian patient, with minor heart attack in 2004, and since then on Metpure XL 25, Clopitab 75, Esoz D40, Tonact 10. On many occassion I have heaviness feeling above navel and goes up to heart and spreads alll over the heart. Normaxin RT has helped but , then again after several weeks it come back again. I can walk 45 minutes every day - brisk walk, and have no probllem. NO stent has been put, but only on medicines. Can you advise why this heaviness in and around ther heart area..
