In the next thirty years, more than half of the adults in an increasingly older and diverse United States population may face cardiovascular diseases, such as heart attacks and strokes.
Recent studies predict that the occurrence of these health issues and their associated costs could triple, reaching $1.8 trillion by 2050.
This alarming projection is drawn from two reports by the American Heart Association, which highlight not only the future prevalence of cardiovascular diseases but also the immense financial burden they are likely to impose.
The rising costs are linked to an increase in several health issues, including high blood pressure and obesity.
Dr. Dhruv S. Kazi, a key figure in this research and a specialist in cardiac care at the Beth Israel Deaconess Medical Center in Boston, describes the current situation as a looming perfect storm.
Over the last decade, there has been a noticeable rise in cardiovascular risks. Uncontrolled high blood pressure, diabetes, and obesity are more common and are major contributors to heart-related diseases.
Cardiovascular disease is a broad term that includes conditions affecting the heart and blood vessels.
This encompasses coronary heart diseases like heart attacks, heart failures where the heart can’t pump effectively, arrhythmias like atrial fibrillation which is an irregular heartbeat, vascular diseases affecting veins and arteries, congenital heart defects, strokes, and high blood pressure.
Specifically, high blood pressure is a major concern as it underlies nearly all cardiovascular conditions and strokes. It’s projected that by 2050, over 60% of the U.S. population will have high blood pressure, up from just over 51% in 2020.
Likewise, the prevalence of other cardiovascular diseases is expected to rise significantly, with stroke rates doubling.
Another disturbing trend is the anticipated increase in obesity rates, which are expected to jump from 43.1% to 60.6%.
This rise is particularly significant among adults between 20 to 64 years, driven by poor diets. Similarly, diabetes rates are predicted to increase from 16.3% to 26.8%.
Children and young adults are not spared from these rising trends. By 2050, a third of all children are expected to be obese, a significant increase from 20% in 2020.
The highest increases in obesity, high blood pressure, and diabetes are expected among very young children and teenagers.
Factors like inadequate physical activity and poor diets contribute to these trends and are expected to affect about 60% of all children over the next three decades.
The demographic shifts in the U.S. are also influencing these projections. By 2030, the last of the Baby Boomers will turn 65, making about one in five Americans over this age, outnumbering children for the first time in U.S. history.
Since the risk of cardiovascular diseases increases with age, this aging population is likely to significantly increase the burden of these diseases in the country.
The ethnic composition of the U.S. population is also changing, with Hispanic, Asian, and multiracial groups expected to more than double in the coming decades.
By 2060, over two-thirds of children will belong to these groups, which traditionally face higher rates of cardiovascular diseases and risk factors.
These projections also highlight significant health disparities. Hispanic adults are likely to see the largest increase in cardiovascular diseases, while Black adults are projected to have the highest rates of high blood pressure, diabetes, and obesity.
Asian adults and children are projected to struggle significantly with physical inactivity.
Dr. Karen E. Joynt Maddox, who chaired the writing committee, points out that while demographic changes contribute to these increases, disparities in disease and risk factors are also strongly linked to systemic racism, socioeconomic factors, and access to healthcare.
However, not all trends are negative. Physical inactivity rates are expected to decrease from 33.5% to 24.2%, and smoking rates are anticipated to nearly halve from 15.8% to 8.4%.
To combat the rising tide of cardiovascular disease and its costs, Dr. Kazi advocates for strategic investments in prevention and treatment. He stresses that a collective effort is necessary to mitigate these challenges and manage the financial impacts effectively.
