Hi All, thank you for all your advice and support. I've cancelled my guest lectures despite protestations from my partner.
He will use GTN spray if required ( he spoke with cardiologist and they said to sit down when he takes it and rest for a few minutes afterwards).
Hopefully his CABG date comes through soon and he starts his road to recovery.
He is exercising ( gently) .
He also seems to be noticing his right hand is paler / yellow compared to his left hand..he asked me to ask if anyone else has experienced this ?
Kind Regards
Cal
