Shortness of breath - heart not pumping adequately

I have been having very bad shortness of breath lately.  It is so bad that I can’t walk from the house to the mail box without stopping half way to catch my breath.  It has gotten worse in the past month.  I went for a stress test.  It was found that “the bottom of heart is not pumping adequately”, what ever that means.  No blockages were found.  I have been scheduled for an echocardiogram this Thursday.  In addition, I have had very bad cramps in the feet, hands, and legs. 

Anyone else have these same symptoms?  If so, what was found to be the problem?
