Should 50% stenosis in one of my coronary arteries be treated? 

Please explain what this means: Cardiac catheterization showed 2 lesions in the proximal LAD, both were 50% stenosis, but otherwise normal coronary arteries. Should this be treated or not? What pro-active measures can I take to preserve my health?

by Texas Heart Institute cardiologist, Roberto Lufschanowski, MD  

Roberto Lufschanowski, MDDear Louise: Two proximal LAD lesions can be significant. The location, size of the artery, etc. will determine the importance of these lesions and the treatment that is needed if any. A few lines will not help much to answer your question. You need to sit down and discuss with your cardiologist the treatment strategy. Make a list of questions so you don't waste any time during your visit so your doctor can discuss your risk factors for heart disease.
