I had classic symptoms of heart failure.
But I was a fat (if very active, walking 10 miles most days) 28 year old, on benefits, on a council estate, suffering depression.
It took two years to get from the GP who thought I was having panic attacks and gave me sleeping pills to deal with waking up at night unable to breath and the constant wheezing... via the GP who ignored an enlarged heart on a chest x-ray, a positive response to a heavy dose of diuretics, nearly dying of flu twice (yes really!), and then eventually getting treatment for the long ignored (didn't have the right numbers) hypothyroid and serious b12 deficiency...
To an Endocrinologist who listened to my heart and found the murmur, sent me to the specialists who found the dead bits of my left ventrical and put me on the right meds..
And then the surgeons who got all excited... until the probability of Ehlers Danlos meant surgery wasn't a sensible option, and then I wasn't exciting any more.
I've lost mobility, independence, a lot of years - I am likely to die from a massive heart attack... whenever (I was given a generous ten years about 12 years ago now).
It is hard not to think that had this been spotted earlier - and I have had several drs point out that the murmur and malfunction will have been there all my life... gradually getting worse, and my records show multiple red flags for Ehlers Danlos if anyone had cared to look - i might be a smidgen better off.
But they didn't listen, they didn't believe my history, they decided I was just fat and lazy.
You can't live life based on 'what if' though.. so I just get on with it.
