It's the only picture I could find with a stupid face being pulled. Had a Coronary artery stent back in summer of 2016. Sent a whatsapp to my missus saying how stupid I looked in a hospital gown.
Had my first mini-heart attack (sounds much more dramatic than it was) cycling up box hill. Just slowed down and carried on plus 20 miles back home. Got up in the morning and sat in front of my computer and had one again. Went into hospital where they said I will need a stent, but appointment was for two weeks later. I felt fine and asked Doc if I could still cycle. He said just don't do anything stupid. Had a few more rides then one evening I went out alone and 15 miles out I got hit again only this time I couldn't cycle through it. I had to limp home at 10mph, just couldn't get any power.
Went into A&E the next day and had the stent fitted the following day. Got it a week earlier than planned ! Win win.
Apologies to the OP for wandering miles off the subject. I would never usually do that (I always do that)
