Hi am new here I am going into Hospital for ablation on 2nd July as have Supravenriculartachycardia. Had heart stress MRI and just been told looks like I have a narrowing and need a angiogram and maybe Stent. I am 51 yrs old and Obese. Struggled for years with weight but sat feeling very disappointed in myself that I have literally done this to myself. So massive wake up call and need to change my lifestyle. Advice from those of you that have accomplished this .
