Excellent advice on the Medic Alert card.
For my dad I printed a foldable credit card size with all the info you named plus a big red cross and bold medic alert on cover with his name, insurance numbers and ICE, inside primary and cardio Dr info, surgical history and meds list. Laminated several copies, wallet, neck chain, and car visor clip-on. Served him very well in severe multi-car pile up when he was unconcious. Cardio implant and blood thinner note was in bold.
And as you said EMTs and OR nurses and Drs really appreciated the quick, concise detailed info when minutes count with cardiac conditions.
he is also apparently posting again
if that is him
