For me, now that I know I have coronary artery disease, I have to depend on the treadmill and cardiolite scan to warn me of further problems. It can truly provide early warning for heart disease, and perhaps help head off a heart attack. Check the bottom of this page for a link to still clips of my last heart catheterization. At least 250,000 people a year die of heart attack within ONE HOUR of the onset of symptoms and before they reach a hospital. Check this site to find out.
Heart disease can be silent, or it can have warning signs.
I had a triple by-pass in March 1997, was lucky and survived. I'm convinced it was the result of my many years of smoking, even though I had stopped 14 years prior. It was a major operation which could probably have been avoided by a proper lifestyle early in my life. Now I'm at higher risk for further heart problems and need regular checkups in addition to drugs and diet. This site can tell you what I learned the hard way.
