In a medical records analysis of information gathered on more than 6,000 people, Johns Hopkins Medicine researchers conclude that simply asking older adult patients about their weight history at ages 20 and 40 could provide real value to clinicians in their efforts to predict patients’ future risk of heart failure, heart attacks or strokes. In a report published Nov. 14 in the Journal of the American Heart Association, the investigators say the younger-weight question is potentially a cost-efficient, high-value “ask” likely to help physicians decide how to advise and treat their older patients, particularly now that many people change primary care physicians throughout their lives, and lifelong health records may not transfer. Heart attacks, strokes and other cardiovascular diseases remain the No. 1 killers of Americans. Heart failure, also known as congestive heart failure, is a condition marked by a gradual weakening and stiffening of the heart muscle, diminishing its ability to pump blood. About 1 in 3 deaths in the U.S. are due to heart disease, according to the American Heart Association. About 92 million American adults are living with some form of cardiovascular disease. About 5.7 million people in the U.S. live with heart failure, and more than half a million are diagnosed each year. More than half of people with heart failure will die within five years of diagnosis, according to the Centers for Disease Control and Prevention.
