Heart Age Test: How Old Is Your Heart Really?
Table of Contents
New research introduces a “heart age” calculator that reframes cardiovascular risk in a more intuitive and personally relevant way, perhaps bridging the gap between knowing risk and taking action.
A groundbreaking new tool is offering a more relatable way to understand cardiovascular disease (CVD) risk, moving beyond customary statistical models to a concept many can intuitively grasp: age. Developed by researchers, this “heart age” calculator aims to make the invisible threat of CVD more tangible, particularly for younger individuals who may not perceive themselves as at immediate risk.
The concept of heart age isn’t entirely new. It builds upon the principles of established risk prediction models like the Framingham risk model. However, the latest iteration, spearheaded by Dr. Nisha detail Khan,leverages the updated American Heart Association‘s PREVENT equations and incorporates the growing public awareness surrounding healthy aging.
Understanding Your Heart’s True Age
To validate the effectiveness of this innovative tool, Khan’s team conducted a extensive study involving over 14,000 US adults aged 30-79 who had no prior history of cardiovascular disease.The data for this analysis was drawn from the National Health and Nutrition Examination Survey. The findings revealed a notable disparity between participants’ chronological age and their calculated heart age. On average, women in the study were chronologically 51.3 years old, but their heart age was calculated to be 55.4 years. For men, the gap was even more pronounced, with an average chronological age of 49.7 years and an average heart age of 56.7 years.
Socioeconomic and Racial Disparities in Heart Age
the research also highlighted the profound impact of socioeconomic factors on heart age. individuals with a high school education or less were found to have a significantly older heart age. More than one-fifth of women and nearly one-third of men in this group had a heart age that was more than a decade older than their actual age.
Moreover,the study uncovered substantial differences in heart age among various racial and ethnic minority groups. Black men, on average, had a heart age 8.5 years older than their chronological age. This gap was followed by Hispanic men (7.9 years older), Asian men (6.7 years older), and White men (6.4 years older). For women, the disparities were also notable: Black women had a heart age 6.2 years older than their true age,compared to Hispanic women (4.8 years older), White women (3.7 years older), and asian women (2.8 years older).
“I think some of the social factors that we highlighted where an individual’s heart age might be older than their actual age, while not surprising, are helpful to see the health of the nation,” stated Khan, emphasizing the tool’s ability to illuminate broader public health trends.
Reframing Risk for Better Engagement
The authors of an accompanying editorial praised the new tool for its ability to “reframe risk in a more intuitive,personally relevant way.” They noted that the approach effectively combines epidemiological data with principles of behavioral psychology. This strategy, they explained, “taps into an intuitive grasp of time and aging, a concept more emotionally salient than a probabilistic 10-year risk estimate and may help bridge the persistent gap between knowlege of risk and engagement in health-promoting behavior.”
Presenting cardiovascular risk in terms of “heart age” is seen as particularly beneficial for younger populations. According to Khan and her colleagues, younger individuals often have a lower absolute risk, which can lead them to overlook opportunities to improve their cardiovascular health. The relatable concept of heart age can make these preventative measures more compelling.
A Tool for Clinicians, Not Just Patients
The research team has made a free online version of the heart age calculator available. However, Khan stressed that the tool is primarily intended for use in consultation with a healthcare professional.”Our goal is not to have this be patient-facing but to have it be targeted to clinicians to help support that patient-clinician discussion,” she explained. “A tool like this is only as useful as the conversation that follows about the opportunities to promote or maintain heart health in optimizing your heart age.”
This approach ensures that the insights gained from the heart age calculator are translated into actionable advice and personalized strategies for improving cardiovascular health, ultimately empowering individuals to take proactive steps towards a healthier future.
Khan reported no relevant financial conflicts of interest.
