angina
"Prior to my diagnosis of heart disease I suffered daily with what I thought was heartburn and indigestion.  I ate Tums like candy.  Sometimes it would get so bad I would chug a couple of diet sodas just so I could burp, which seemed to help.   Then I had a stress test which led to having a heart cath done.  I have a 100% blockage in my RCA and two other smaller blockages.  Once I started Ranexa all of what I used to believe was heartburn/indigestion stopped.  It is amazing."
