A new study from Yale University has found that men and women under the age of 55 face different risks when it comes to heart attacks. While heart attacks are often seen as a concern for older adults, this research shows that young adults—especially young women—also need to be aware of their heart health.
The study highlights how some risk factors have a much stronger impact on women than men and suggests that a one-size-fits-all approach to prevention may not work.
The researchers looked at data from 4,528 people—half of them had suffered a heart attack, and the other half had not. They compared a wide range of health and lifestyle factors to see which ones were most likely to be linked with heart attacks in younger adults.
The team found that the main risks for women included diabetes, smoking, depression, high blood pressure, low income, and having a family history of heart attacks. For men, the most important risk factors were smoking and family history.
One of the most important findings was that certain conditions—like diabetes, depression, high blood pressure, and poverty—had a much stronger effect on women than men. For example, women with diabetes were at a much higher risk of having a heart attack than men with the same condition.
This suggests that women’s bodies may react differently to some of these common health problems, and their heart health may be affected in more serious ways.
In both men and women, seven risk factors explained the majority of heart attack risk: diabetes, depression, high blood pressure, smoking, family history, low income, and high cholesterol.
These factors were responsible for about 84% of the total risk in women and 85% in men. The good news is that many of these risks are modifiable—meaning they can be improved or controlled with the right treatment and lifestyle changes.
The study authors say that these findings point to a clear need for sex-specific strategies in preventing heart attacks. In other words, doctors need to look more closely at how these risk factors affect men and women differently. Women especially may benefit from more targeted care and earlier screening for conditions like diabetes, high blood pressure, and depression.
The researchers also called for greater public awareness. Campaigns like the American Heart Association’s “Go Red for Women” are already helping to educate women about heart disease, but this study shows that the focus should include younger women too—not just those over 60.
Doctors and healthcare providers should also make sure they are following the latest guidelines and using the best strategies to help both women and men lower their heart disease risk. This includes things like promoting healthy diets, encouraging exercise, helping patients quit smoking, and making sure conditions like diabetes and high blood pressure are properly treated.
This important study, led by Dr. Yuan Lu and published in JAMA Network Open, reminds us that heart disease is not just a problem for the elderly. Many young adults—especially women—are at risk, and understanding the differences in how these risks affect each sex can lead to better care and healthier lives.
