According to the American Heart Association, without improved prevention and early detection, the number of women with cardiovascular disease is expected to rise significantly in the coming decades.
Using historical data from national health surveys and population growth estimates, the association projects that the percentage of women with at least one type of cardiovascular condition will increase more than a third, from 10.7% in 2020 to 14.4% by 2050.
Cardiovascular disease already ranks as the leading cause of death for women in the U.S., with coronary heart disease being the most prevalent form. This occurs when fatty deposits, known as plaque, accumulate in the arteries, hindering the flow of oxygen-rich blood to the heart muscle. The report also discusses other conditions, including heart failure, which affects the heart’s ability to pump blood, atrial fibrillation, an irregular heartbeat, and strokes.
Dr. Stacey Rosen, the volunteer president of the American Heart Association, emphasized that these findings should serve as a call to action. The association regularly releases scientific statements and guidelines based on expert opinions to encourage longer, healthier lives.
While there have been significant advancements in treating heart disease, it’s crucial to rethink strategies for prevention and early detection, Rosen noted.
The authors analyzed multiple years of data from two key national surveys: the National Health and Nutrition Examination Survey from 2015 to 2020, which gathers information on health and diet, and the Medical Expenditure Panel Survey, which inquires about healthcare costs and usage among families and individuals.
By applying census forecasts for population growth, the authors extended historical trends into future projections.
Among adult women, expected increases in cardiovascular disease rates include:
- Coronary heart disease: from 6.9% in 2020 to 8.2% in 2050.
- Heart failure: rising from 2.5% to 3.6%.
- Atrial fibrillation: increasing from 1.6% to 2.3%.
Dr. Karen Joynt Maddox, a cardiologist involved with the report, pointed out that demographic shifts due to an aging population are contributing to these increases.
Risk Factors for Younger Women
Growing rates of diabetes, obesity, and high blood pressure also play significant roles, as each of these factors elevates the risk for heart disease. If current trends persist, high blood pressure rates among adult women are projected to rise from 48.6% in 2020 to 59.1% in 2050. Similarly, diabetes could jump from 14.9% to 25.3%, and obesity rates may escalate from 43.9% to 61.2%.
These risk factors are becoming more prevalent across all age groups, including young women aged 20 to 40. Obesity is expected to rise significantly among young girls too, projected to increase from 19.6% to 32.0%. Joynt Maddox expressed concern that this trend may lead an entire generation of girls and young women to face cardiovascular diseases at earlier ages.
Interestingly, survey data suggest a slight decrease in poor dietary habits and increased physical activity among women, while smoking rates continue to drop. On the flip side, sleep issues are expected to rise.
Many of these negative trends are anticipated to have a more significant impact on Black, Hispanic, Indigenous, or multiracial girls and women.
Impact of Weight-Loss Medications
The study didn’t factor in the growing trend of using GLP-1 medications, which are powerful treatments for weight loss and Type 2 diabetes. Research indicates these medications may also lower the risk of repeated heart attacks and heart failure, though the long-term impact on cardiovascular disease and obesity risk factors remains unclear. Rosen highlighted that ongoing safety studies are necessary.
Moreover, many people discontinue these medications due to side effects, often regaining lost weight. Accessibility is another concern; not all communities can afford the costs associated with GLP-1 drugs, which may widen disparities in cardiovascular health.
Despite these challenges, Joynt Maddox encourages women to take proactive steps now to reduce their lifetime risk for heart issues. This includes regular check-ups, adhering to prescribed treatments, and developing healthy habits related to diet and exercise. Such practices are particularly vital during pregnancy and menopause when risks can change.
After all, it’s never too early or late to start. Rosen reminds us that about 80% of heart disease risks can be prevented, and it all begins with awareness.
