Hopefully a couple of helpful tips from my own experience.
If you'd have said 'screening' or 'blood pressure' to me in my 20s or 30s I'd probably have laughed, said I'm fine and isn't that just for old people anyway? My mind has changed.
In my mid 40s I was having investigations for an episode - which they eventually put down to a muscular event. But they did a thorough job (NHS initially then private) and found that I had a genetic heart condition that I had no idea about and hadn't had any symptoms for. It effects about 1 in 500 people and one of the variants unfortunately kills otherwise fit and healthy young people including Gabby Logan's brother. Thankfully I don't have that strain, although there was still a low sudden death risk which reduces as you get older. Worrying, especially given both my parents have had heart issues. Ultimately, no intervention needed except having to manage blood pressure - mine wasn't extreme, but was raised and very high BP does run in the family.
Why writing now? We're a few years on and last night I saw the cardiologist for an MOT - he's going to run some further tests for precise data, but he's happy its being managed well and has actually removed some restrictions he originally put in about the intensity of exercise I could do. Bully for me!
The point is that I had no idea about this condition or how long I'd had it. It was only found by accident and if left unmanaged it may only have revealed itself at the problem stage. A simple ECG was all that was needed to identify that there was a problem needing investigation. So if you do get the chance through private providers or otherwise please do take up any screening options available. You may feel fine, but you never quite know what's going on below the surface.
As for blood pressure they call it the Silent Killer for good reasons and the more you learn about it the more you realise just how important it is. Do get yours checked by a doctor from time to time and you can get a home monitor for about £30 too.
