If high quality CPR is started immediately and continued until the heart starts beating again, it’s totally possible to get through cardiac arrest with very minimal brain damage. The problem is that for most people, they don’t get immediate and continuous CPR

The old kidneys don’t get broken down, they just stay in your body

Cardiac cath are done under “conscious sedation,” and is not open heart surgery. It is done by threading a small tube (catheter) through either the radial or femoral artery up to the heart arteries and a stent is deployed through that. Usually the patient is sedated with midazolam and fentanyl (short acting benzo and opioid) and will be able to answer questions and follow commands but will be pretty sleepy, shouldn’t feel pain, and won’t remember much. The whole procedure usually lasts less than an hour.

Open heart surgery is an entirely different beast. Those patients are under full anesthesia with ventilator and sometimes bypass machine.
