Hi, Im 43 and recently went for a treadmill test as i experience throat tightening upon excertion. the result showed significant changes in my st depression and im due to go for an angiogram in december. the cardiologist has put me on tablets and aspirin and given me a spray to relieve symptoms. my gp tells me i am at risk of heart attack. could they have this wrong? i am diet controlled diabetic, mum had angina and died at 69 when arteries were so blocked around heart and her lungs filled with fluid; dad has mild angina. i am currently suffering with indigestion but i do actually burp with it so does this mean its not connected....any advise would be appreciated
