People with a “hardening” of the abdominal aorta are at increased risk for heart attack and stroke, according to a new study. Atherosclerosis is the medical term for a narrowing and hardening of the arteries caused by a buildup of plaque. The aorta is the largest artery in the body, carrying oxygen-rich blood from the heart; the section of the aorta in the abdomen is called the abdominal aorta. Researchers used MRI to examine plaque accumulation and abdominal aortic wall thickness in more than 2,100 people in Dallas County, Texas. During a follow-up period of nearly eight years, 143 of the participants, whose average age was 44, had a cardiovascular event such as a heart attack or stroke. Thirty-four of those events were fatal.
