I am a 46 year old male. I was in reasonably good shape. I loved to hike, walked up to 10k every few days.  I loved to mountainbike ride.  About November 2007 I started getting "indigestion"... or heavyness in the chest after eating.  If I ate anything and then went for a walk, it would be particularly uncomfortable.  Over the winter I slowed down with the exercise. Mid February I started getting these weird dizzy / lightheaded  feelings at the oddest times.  It was kind of like the feeling you get when you jump up suddenly, but I'd get it just standing.  Around the beginning of April, the heavyness in the chest got nastier every time after I ate. In addition to this, I had mild discomfort in both my arms.  Indigestion sucks huh?  On May 7th, 08, I had some salad about 9:30, then went to bed about 11:00. I woke up at 3:00AM with a real serious case of "indigestion".  After attempting to fix the problem with a glass of water, I began to clue in that my problem might just be a bit more serious. After all, My mother died young of a heart attack, as did her mother.  I got dressed and clutching my chest, drove to emergency, where they immediately got me on morphine and began to treat me for a heart attack.  That was nice. I asked for a phone so I could call into work to let them know I'd be a bit late.  The hospital had different ideas.  I ultimately spent the week in the hospital and had quad bipass surgery the following week. My surgery was over three weeks ago and I'm doing well.  I have since talked to many people, including people in the medical field, who have had heart attacks.  Many of these people ignored the symptoms, just like I did.In fact, I now that many people mistake pre heart attack symptoms, or an actual heart attack as indigestion.  My warning to you is... if you are over 40... KNOW THE SYMPTOMS of heart trouble.  If you have any of the symptoms,or just feel "weird"...  see your doctor.  I was lucky, I know people who weren't.  Don't ignore the symptoms.
