Heart Disease and Stroke in Women: 6 in 10 Will Be Affected by 2050

Heart disease is already the leading cause of death for women in the United States. Now, a sweeping new report from the American Heart Association warns that the crisis is about to get significantly worse, and that younger women are increasingly in the crosshairs.

According to NBC News, a new scientific statement published on February 25 in Circulation, the American Heart Association's flagship journal, projects that nearly 6 in 10 women in the United States will have at least one form of cardiovascular disease by 2050. That is up from roughly 1 in 10 today. And the rise is not just among older women. Younger women and even girls are increasingly at risk.

Heart Disease in Women: What the Numbers Show

According to the American Heart Association's press release, the percentage of women with at least one type of cardiovascular disease is projected to climb by more than a third, from 10.7% in 2020 to 14.4% in 2050. But that headline figure actually understates the problem because it includes women of all ages. When researchers focused on younger women aged 20 to 44, the findings were even more striking.

According to Scientific American, nearly one-third of all women between the ages of 20 and 44 will be diagnosed with some form of cardiovascular disease by 2050.

The projections break down across specific conditions as well. According to NBC News, the rate of coronary heart disease among adult women is expected to rise from 6.9% in 2020 to 8.2% in 2050. Heart failure is projected to climb from 2.5% to 3.6%. Stroke rates are expected to rise from 4.1% to 6.7%. Atrial fibrillation, an abnormal heart rhythm condition, is projected to go from 1.6% to 2.3%.

Obesity, Diabetes, and High Blood Pressure Are Driving the Crisis

The researchers behind the statement are clear about what is causing these trends. According to the American Heart Association, the three main drivers are rising rates of high blood pressure, obesity, and diabetes. All three conditions independently raise the risk of heart disease and stroke, and all three are getting worse across the female population.

According to STAT News, nearly 60% of women will have high blood pressure by 2050, up from 50% in 2020. Diabetes rates could increase by 10% by 2050, while obesity may rise by roughly 17%.

The concern does not stop at adults. According to STAT News, nearly one-third of girls aged 2 to 19 could have obesity by 2050, up from 19.6% today. Dr. Karen Joynt Maddox, a cardiologist at Washington University in St. Louis and lead author of the study, said she worries a great deal about young people being set up to have heart problems in their 30s and 40s rather than their 60s and 70s.

Black and Brown Women Face the Highest Risk

The report is not just a warning for women broadly. It highlights stark racial disparities that are expected to persist and worsen. According to Scientific American, Black women currently have the highest rates of high blood pressure, obesity, and diabetes among all demographic groups, and that is projected to remain true in 2050. They are also expected to see the greatest increases in heart failure and stroke compared to other groups.

Dr. Nanette Bairey Merz, a cardiologist cited by Scientific American, described the compounding disadvantage facing women of color in underserved areas as a double burden, where race, geography, and lack of healthcare access all pile on top of each other.

What This Means and What Can Be Done

The study's authors and outside experts are clear that these outcomes are not inevitable. They describe the report as a call to action for better prevention and early detection, not a fixed prediction.

According to NBC News, Dr. Stacey Rosen, volunteer president of the American Heart Association, said the organization has developed tailored prevention guidance for women at every life stage, from childhood through menopause. She emphasized that as much as 80% of heart disease and stroke is preventable.

One major factor the study did not account for is the rapid rise of GLP-1 weight-loss and diabetes drugs like Ozempic and Wegovy. According to STAT News, the projections are based on data from 2015 to 2020, before these medications became widely used. Dr. Joynt Maddox said she is cautiously optimistic that their growing use could begin to change the obesity and diabetes trajectories, though the long-term cardiovascular impact of these drugs is still being studied.

The findings were published on February 25, 2026, in Circulation and represent the American Heart Association's most comprehensive forecast yet on women's cardiovascular health through mid-century.
