Hello KazziCas
from me too!
Sorry to hear about the heart problems in your family but as you probably realise - lifestyle factors play a huge part in whether you would be susceptible even with genetic pre-disposition. Sounds like you are doing the right things by keeping fit and also I presume you are attending to other areas of your health to reduce your own risk - ie eating healthy low fat diet, no smoking, minimal alcohol, low salt and of course keeping to healthy BMI.
As you are two years post-menopause - your oestrogen levels overall will be at their lowest they will go (they still fluctuate a wee bit but not significantly) - and low oestrogen can cause anxiety and mood. Are you suffering from hot flushes and sweats also? The good news is that taking HRT will help protect your heart for longer - in fact it is recommended for all women who reach menopause before the average age of menopause which is around 51 - and provides benefits to women after this age.
Good idea to go to the doctor to get checked out, especially in view of your family history - but if all is clear why not think about HRT, for anxiety as well as your heart?
"Mental pause" anxiety - that's an interesting perspective
Let us know how you get on
