My cardiac catheterization showed "minor luminal irregularities" in lad, circumflex, ramus, with co-dominant coronary circulation. What does that mean?

Minor luminal irregularities refers to an abnormal narrowing of the arteries of your heart, according to the AMA. Co-dominant refers to how your heart pumps blood, meaning it is using both of the proper ones, making neither major artery dominant.

This is usually considered mild heart disease, due to the luminal irregularities.

The term "lumen" refers to the inside space of a blood vessel through which blood flows. An irregularity in the lumen can mean a variety of things but often refers to changes in the shape or smoothness of the artery's interior surface. This could be due to the buildup of plaque, which is a common cause of coronary artery disease.

Has your doctor put you on any medications?
