angina
"To me, this is a wonder drug!! I'm serious! I'm not saying that my chest pains with palpitations are completely gone because they're not. Yet, with Ranexa, I can deal with it. The first time I began taking it I walked about 3-4 blocks without stopping to catch my breath. At first it scared me thinking I did or was doing something wrong. But it was the Ranexa that made the difference!"
