My Twin Sister Had Pacemaker Surgery A Couple Hours Ago.

My twin sister had pacemaker surgery a couple hours ago. She is in Georgia and I'm in Oregon. I was wondering, can this be caused by her, she is very stressed all the time, and "never gets everything done" etc. I was wondering since I'm her twin if there's something I should be looking for in my routine? Thank you (By the way, we're fraternal) and we're 78 1/2 years old.
