Something simmilar happened to me this past winter, Not a heart attack but very scary well 5 cardiologists later and a ####load of tests and wearing all kinds of monitors they still don't know what's wrong with me but I still get pulpitations and atrial fibrulation.I had an interventional cardiologist sit on the foot of my bed and ask me if I wanted to live to be 45 .I was 40 at the time and had just been wheeled out of the cath-lab after having an angioplasty following a myocardial infarction (heart attack) . He was very blunt and explained that if I didn't stop smoking the odds were that I would be dead in less than 5 years. His words have stuck with me for 6 years and every time I want to light one up I think of him.
Anyhow i started going to the gym, eat fruit and veggies now and (was a steak and chips guy) and figger it's time to quit the smokes too. I am only 23 God-willing hope to make 80
Wish me luck guys, I started to quit tonight.
The long process of recovery....
