I had a heart attack in 2012 , on my way to my exercise class. I got off the bus and felt as though an elephant was standing in my chest, needed to take deep breaths. I had no pain whatsoever, and no other symptoms, so thought, as you do, that it would go away. I walked to the town hall, then thought, I'll go to the surgery. When the receptionists heard me, they just took over. The Dr was great and did some tests, then called the paramedics and soon I was in an ambulance on the way to hospital. Next day. I had an angiogram and a stent fitted and was home after four days.
Thank you NHS.
