New Insights Into Heart Health
Recent research suggests that your heart might actually be older than you think. A study by Northwestern Medicine indicates that many American adults have a “heart age” that significantly surpasses their actual age.
According to a press statement from the university, the discrepancies seem to be more pronounced among men compared to women, as well as among Black and Hispanic individuals, particularly those with lower education levels and income.
To aid in assessing heart age, the researchers introduced a free online tool designed to make these calculations. Following guidelines from the American Heart Association, the Prevent Risk Age Calculator evaluates an individual’s risk of heart disease through various factors, including blood pressure, cholesterol levels, smoking habits, current medications, and diabetes presence.
Interestingly, the tool presents risk levels as an age rather than as percentages. Dr. Sadiya Khan, a senior author of the study and professor of cardiovascular epidemiology at Northwestern, emphasized that translating complex health data into a more relatable age format might encourage better understanding among patients and clinicians alike. This, she believes, could be crucial in preventing heart disease.
“Many individuals who could benefit from medication to mitigate their risk of heart attack, stroke, or heart failure aren’t actually receiving it,” she noted.
The aim is to create a framework where discussions around heart disease risks can happen more openly, enabling doctors and patients to engage effectively about preventive measures.
Data Collection and Findings
In testing the tool, researchers gathered data from over 14,100 American adults, ages 30 to 79, with no prior history of heart disease. The data were sourced from the National Health and Nutrition Examination Survey (NHANES) collected between 2011 and March 2020.
On average, women had a heart age of 55.4, almost four years older than their actual age of 51.3. Men, on the other hand, had an average heart age of 56.7, which is seven years more than their typical age of 49.7. Notably, over 22% of women and approximately 33% of men with a high school education or less displayed a heart age that was over a decade older than expected.
The findings were published in the journal Jama Heart Disease, shedding light on a concerning issue, as heart disease has been the leading cause of death in the U.S. for over a century. It raises hopes that increasing awareness around heart health could lead to more proactive care.
Dr. Khan mentioned that awareness is particularly essential for younger individuals who might not recognize their heart disease risk. However, she cautioned that this calculator shouldn’t replace a doctor’s in-person evaluations.
While the research team highlighted the necessity of testing this tool to ensure clarity, they acknowledged that one limitation lies in how optimal risk is defined, as it can influence risk calculations. They believe population-based percentiles might serve as an alternative way to convey risk, though this is subject to the overall health of the population.
In conclusion, future studies will be necessary to determine how cardiac age impacts lifestyle choices, preventive therapies, and overall patient outcomes.
