USA: Organs older than expected: Simple online tool calculates the heart

Published on August 11, 2025

With the usual markers for heart health, Prevent calculates the heart and the associated risks. The age of the heart can be determined with a newly developed computer.The results are intended to help those affected to prevention and prevent cardiacs. The hearts of a large part of the people in the USA are several years older than the people themselves. This is the result of an investigation by researchers from Northwestern University Chicago.Before the study, the research team around Sadiya Khan developed an instrument called Prevent, which can determine the heart and the resulting risks with the help of health data such as blood pressure, cholesterol and smoking status. The reason: So far, the risk of heart disease has been calculated and communicated in percent.Then doctors said something like: "Eight of one hundred people with their profile could suffer a heart attack in the next ten years," the team writes in a university statement.But it seems as if this type of communication and risk assessment was not well understood by those affected.The team around Khan therefore wanted to go other ways. "We hope that this tool will help doctors and patients to discuss the risk of heart disease more effectively so that we can better inform about which therapies can prevent heart attacks, strokes or heart failure from the outset," said Khan.The determined organist could help individuals understand how high their risk is compared to chronological age.It can motivate to comply with lifestyle changes or recommended preventive measures, the researchers whose study results were published in the journal "Jama Cardiology". Test with data from more than 14,000 people In order to check the results of the newly developed instrument, the researchers used the data of more than 14,000 adults between the ages of 30 and 79.All subjects live in the USA and took part in the representative investigation "National Health and Nutrition Examination Survey" from 2011 to 2020.All people had no cardiovascular diseases at the beginning of the investigation. The evaluation of the data showed that the average age of the heart among women is 55.4 years and chronological age is 51.3 years.These values are further apart for men.The average cardiac was calculated at 56.7 years.In contrast, the actual average age is 49.7 years. The researchers saw the greatest tension between the calculated and actual heart of the heart in people with low education."In almost a third of men with high school degree or less education, the heart was more than ten years above their actual age. Even in adults who identified as black or Hispanic, the discrepancy between heart and chronological age was significantly greater," says the message. Improve the health of all people The findings are intended to help reduce the number of deaths from heart diseases in the future."Many people who should take medication to reduce their risk of heart attack, stroke or heart failure do not take them. We hope that this new heartbreaker supports the discussion about prevention and ultimately improves the health of all people," sums up study director Khan. Although the newly developed tool is freely accessible and free, you should only use it as part of a doctor-patient call.
