hi and welcome. I would await the results of the stress test and echo. the stress test will determine how you are at, with ya ticker and oxygen, whilst the echo has a look at the ticker via ultrasound. if bloods are good, this is a good starting point. I do not know anything on it, the forum is slow at the moment. keep strong. I will have a look see at what I find.
