The cost and system of health care in different countries is really an interesting subject.
Within my own family we had a very interesting apples to apples example this past year.
My DH had a long term heart valve issue which was being watched. He ended up needing bypass surgery to have the valve repaired. This was done withing 2 weeks of some new symptoms starting. After surgery and while on the constant monitoring in the CCU, they found some potential issue with his heart rhythm, has has always been very fit except for the valve problem. He went NPO and early the next morning a cardio rhythm doc came to see him. After taking a family history in which several Uncles, his Dad and one of his Aunts all died from sudden heart attacks ( this was about 25 years ago a presumed to be the result of blocked arteries) the doc said this could be a genetic rhythm issue I think we'll just put in a pacer/defib for safety and your peace of mind. You might never need it, because right now it's not that big of a problem, but better to be on the safe side. Within an hour he was getting his new device.
I have a first cousin in England 54 and dealing with a few issues with her heart. She had a pacer in 3-4 years. Suddenly had such bad angina she went to the ER thinking it was a heart attack. They told her she needed her pacer replaced and put in hospital to watch her. She mentioned to the docs her regular doctor had been telling her for over a year that her pacer battery was getting to the end of its charge. They sent her home with meds for pain, told her not to go to work and they would call her with a replacement date. They called her back in 12 DAYS and schedule her surgery 15 DAYS after that. She told them she was having bad angina attacks 3 or 4 times a week. They gave her a different med on the phone. Then they told her, oh well maybe you do have blockage and we'll just do the artery test when you get your pacer in case you need a stent. My poor cousin spent the next 2 weeks in pain and extremely worried that something major might go wrong while she was sitting at home waiting.
Our health care system is far from perfect, but from my own experience it seems to be a case of people thinking the grass is greener on the other side of the fence. My cousin has worked her entire adult life and paid a pretty penny into the British health care system.
