I was born with a heart murmur, which means one of my heart valves doesn’t close properly. I believe it’s in the right atrium; however, I keep wondering if this is a condition that will continue to get progressively worse over time. Also, are there ways to work my heart that could possibly lessen the symptoms I seem to have because of this condition—fatigue, rapid heart rate, and shortness of breath? I’m only 28, but sometimes the condition leaves me so tired that I can’t get through the day. I exercise regularly (5 days a week), but is there anything else I can do or even avoid to make my heart stronger or to lessen these symptoms?
