As a woman, I am especially concerned with heart disease. It’s the No. 1 killer of women in the U.S., attributed to 1 in 3 deaths each year. What’s even more concerning is the added risk of a specific heart attack unlike anything that’s commonly seen. A heart attack that not only affects healthy older women but women in their 30s as well. These heart attacks are caused by spontaneous coronary artery dissection, or SCAD.
