I don’t think this is brand new, maybe a month or so old, but now you can download the medical/health knowledge cards on Google as a PDF. Yes, you can print out the information and I guess give it to your doctor. Update: After researching more, this has been a feature since September 2015.

Harris Schachter spotted it and posted a screen shot on Twitter but I believe anyone can see it now. Just Google [heart attack symptoms] and you will see the medical card on the right, and at the bottom is a download as PDF.

I guess Google got feedback that the users want to download it and print it?
