Had a full blown heart attack myself, 5 years ago, but try as I might, I could not kick the stinkies until I came across the vaping gear available. Had tried the e-cigs you see advertised in the press but gave up on them after a very short trial. Been vaping for a couple of months now and feel the benefit of kicking the stinkies into touch. Not touched, or even craved one for 2 months now since I started vaping. Only point I would make is that If I try a juice with too high a nicotine content, then I find I need a couple of squirts of GTN. So I mix using the bare minimum of nicotine, using just enough to satisfy the cravings and keep me off the stinkies, but not too much to cause problems. Also with mixing my own juice I am gradually reducing the amount of nicotine I include in the mix. Though my advice would be to check with a health professional. Everyones situation is different an it really is unwise to accept a 'one size fits all' answer. P.S. I was getting through over 50g of Golden Virginia every week. God only knows how I avoided having a second attack!
