New data point to a troubling paradox in heart health. While awareness of cardiovascular risk and access to advanced treatments have steadily improved, overall progress in the United States has slowed—and in some areas, reversed.
According to Rishi Wadhera, lead author of the 2026 cardiovascular statistics report published in the Journal of the American College of Cardiology (JACC), the challenge is largely specific to the U.S.
“Many high-income countries are facing rising obesity and diabetes,” said Wadhera, an associate professor at Harvard Medical School and Beth Israel Deaconess Medical Center, as well as a faculty member at the Harvard T. H. Chan School of Public Health.
“What sets the U.S. apart is how consistently these risks result in poorer cardiovascular outcomes—and how deep the disparities are across income levels, race, ethnicity, and geography.”
The report also raises alarm about younger adults. Newly released research shows a sharp increase in hospital death rates from severe first-time heart attacks among people aged 18 to 54. Although most of the deaths occurred in men, women experienced higher mortality rates once hospitalized.
Among the most striking findings: nearly one in two U.S. adults has high blood pressure, a figure that has remained largely unchanged between 2009 and 2023. Despite advances in treatment, care gaps persist. Only about two-thirds of adults with hypertension receive medical treatment—a rate that has shown no improvement in more than a decade.

These gaps have deadly consequences. Between 2000 and 2019, deaths linked to hypertension-related cardiovascular disease almost doubled, rising from 23 to 43 per 100,000 people. Men were more affected than women, and Black adults faced significantly higher death rates than white adults. Overall, younger Americans are shouldering an increasing burden of heart disease.
Still, the report highlights areas of progress. Deaths from coronary artery disease fell by roughly 50 percent between 2000 and 2020, and the quality of care for heart attack and stroke patients has improved. Smoking rates have also declined substantially, demonstrating how research and sustained public health campaigns can produce real gains.
However, these improvements are uneven.
Smoking remains far more common among lower-income adults, and while most Americans understand the importance of diet and exercise, many live in environments that make healthy choices difficult—marked by limited public spaces, poor access to nutritious food, and transportation systems that rely heavily on driving.
Together, the findings paint a picture of stalled momentum: meaningful advances in treatment and knowledge, undermined by persistent inequities and systemic barriers to prevention and care.
