Is Your Heart Older Than You? New Research Reveals Surprising Insights on Heart Age and Disease Risk
Recent research indicates that your heart might be older than your actual age. A study conducted by Northwestern Medicine has revealed that for many American adults, their “heart age” is several years ahead of their chronological age.
The disparities are more pronounced among men, as well as within Black and Hispanic populations and those with lower educational and income levels. This information was highlighted in a press release from the university.
A New Tool to Assess Heart Age
To assist individuals in determining their cardiac age, researchers created a free online tool known as the PREVENT Risk Age Calculator. This calculator uses guidelines from the American Heart Association to assess heart disease risk based on various factors, including blood pressure, cholesterol levels, smoking status, medications being taken, and the presence of diabetes.
Instead of presenting risk levels as a percentage, the calculator provides results in the form of an age. This approach is designed to simplify complex health information for better understanding.
Dr. Sadiya Khan, the study’s senior author and a leading expert in cardiovascular epidemiology at Northwestern University Feinberg School of Medicine, explained that heart age could offer significant benefits. She emphasized that it translates intricate risk factors for heart attacks, strokes, or heart failure into a more familiar concept — age — making it easier for both patients and healthcare providers to engage in meaningful discussions about heart health.
Empowering Prevention Discussions
According to Dr. Khan, the goal of the calculator is to enhance communication between doctors and patients regarding heart disease risk. This improved dialogue aims to ensure appropriate therapies are implemented to prevent serious cardiovascular events.
The Study Population
The research involved testing the PREVENT Risk Age Calculator on over 14,100 American adults aged between 30 and 79, all of whom had no prior history of heart disease. Their data was taken from the National Health and Nutrition Examination Survey, which recorded information from 2011 until March 2020.
Findings on Heart Age
The results were striking. On average, women demonstrated a heart age of 55.4, which is nearly four years higher than their actual average age of 51.3. In contrast, men exhibited an average heart age of 56.7, marking a seven-year increase over their chronological average of 49.7.
The data showed that more than 22% of women and 33% of men with only a high school education had a heart age exceeding their chronological age by over 10 years.
This compelling research was published in the prestigious journal JAMA Cardiology, marking another step in understanding and managing heart health.
Addressing the Heart Disease Epidemic
Heart disease remains the leading cause of death in the United States, a grim statistic that has persisted for over a century. Dr. Khan notes that a significant number of individuals who could benefit from medications to lower their risk of heart issues are not receiving the necessary treatment.
The heart age calculator holds promise that more comprehensive awareness of heart health risks will promote preventive care strategies. Dr. Khan hopes this tool will facilitate discussions around prevention, ultimately leading to improved health outcomes for individuals.
Engaging Younger Populations
Particularly for younger adults, who often lack awareness regarding their heart disease risk, this tool could be crucial. It provides an avenue for individuals to gain insights into their cardiovascular health in a straightforward manner.
While the heart age calculator is a valuable resource, it is essential to note that it should not replace assessments conducted by healthcare professionals.
Understanding Limitations and Future Research
Researchers caution that the assessment’s accuracy is influenced by various factors, including how “optimal risk” is defined. They suggested that focusing on population-based percentiles of risk might furnish additional context for risk communication.
Comprehensive testing of the heart age tool is necessary to confirm its effectiveness and clarity. Dr. Khan highlighted the need for future research to evaluate the impact of heart age on lifestyle choices, the adoption of preventive therapies, and overall patient outcomes.
Overall, this innovative approach to understanding heart health underscores the importance of awareness and proactive measures in combating cardiovascular disease.
