You need to see your cardiologist. minimal blockages are not normal for a woman in her 40 s, maybe her 60 s. Also women with a heart disease are 10 times more likely to be underdiagnosed therefore leading to more extreme cases when they are older. I would see a cardiologist specializing in women. Women s chest pains or angina present in a different pattern and fashion than do men. Women typically have a more heart burn type feeling, a burning to the right side (i.e. arm or chest) than the left (although the left is still a strong indicator in both sexes). Heart rate can vary depending on your mood, what you were just doing etc. Hope this helps.
