The good doctor (Robert L. Huang) at the Chattanooga Heart Institute may have saved my life. Last May, the week before holiday I was out fishing early one morning. Experienced slight discomfort (not pain) in chest. I thought it was gas. It went away and I stayed and fished most of the day. Long story short, this occurred three (3) more times. I awoke one more at 200am with this same discomfort and decided to go to ER. Heart Attack, most likely several. Stent placed in 90% blocked artery. Went home next day. Dr. James Marcum is my cardiologist. Listen to your body, take care.
