I work at a small community hospital on a PCU. Our hospital has a cath lab and CV surgeon. We see patients on a regular basis that present with positive cardiac enzymes and abnormal EKG. I work night shift and our cath lab is only open during the day with someone on call at all times. The only time I have seen them open the cath lab at night is for patient presenting in ER with a STEMI. I have taken care of plenty of patients with acute MI that we put on hep. gtt and nitro, etc.. till the cath lab opens in the am. Just curious if it is like this at other hospitals or if most do caths 24/7.
