Researchers from the University of East Anglia (UEA) have developed an innovative medical tool that can estimate how fast a person’s heart is ageing compared to their actual age. This tool, based on data collected from 557 people across the UK, Spain, and Singapore, could revolutionize the way doctors assess heart health and provide personalized care to patients at risk of heart disease.
How the Tool Works
The new heart-aging tool uses data from MRI scans to calculate the “functional age” of a person’s heart. Researchers gathered MRI data from individuals with a range of health conditions, including obesity, diabetes, and high blood pressure. The study participants came from diverse backgrounds, with data from the UK, Spain, and Singapore contributing to the development of the formula.
Dr. Pankaj Garg, a cardiologist leading the research, explained that the tool takes into account various factors that contribute to heart health, including the impact of certain medical conditions. By comparing the functional age of a person’s heart to their actual biological age, doctors can gain new insights into how fast a person’s heart is ageing.
Health Risks Speed Up Heart Ageing
The study, published in the European Heart Journal, found that individuals with health risks, such as obesity, diabetes, and high blood pressure, had hearts that were, on average, 4.6 years older than their actual age. However, the gap between a person’s biological and heart age was even larger for people with obesity. For these individuals, their hearts were often decades older than their biological age, indicating a much faster rate of heart ageing.
This acceleration in heart ageing can be alarming, as it may put people at a higher risk for heart disease, heart attacks, and strokes. Dr. Garg highlighted the importance of understanding this relationship: “People with conditions like diabetes or obesity often have hearts ageing faster than normal.” The tool developed by UEA’s research team aims to help medical professionals identify such risks earlier, allowing for more targeted and effective treatments.
Personalized Lifestyle Changes to Slow Heart Ageing
The researchers believe that this heart-aging tool could play a significant role in helping patients make more informed lifestyle choices. By knowing that their heart may be ageing faster than expected, individuals may be motivated to take action. Simple lifestyle changes, such as improving nutrition, increasing physical activity, and managing stress, could help slow the progression of heart ageing and reduce the risk of developing heart disease.
Dr. Garg stated, “It’s about giving people a fighting chance against heart disease.” The idea is that by using the tool to assess heart age, doctors can offer personalized advice and interventions that may improve long-term health outcomes for patients. Whether it’s encouraging more physical exercise or recommending dietary changes, the hope is that this personalized guidance will help slow down the clock on heart ageing and ultimately reduce heart disease-related deaths.
Limitations and Future Research
While the heart-aging tool shows great promise, the study does acknowledge several limitations. One concern raised by the researchers is survivor bias. Since the study only included individuals who had lived with health conditions like obesity and diabetes into older age, the results may not be applicable to younger people with these conditions. The sample size was also relatively small, which means that further testing is needed to confirm the tool’s effectiveness in a broader population.
Additionally, the heart-aging formula has not yet been tested on the general population. The tool has primarily been tested on people who already have known risk factors for heart disease, so its usefulness for individuals without such risk factors is still unknown. Further research is necessary to determine whether the tool can be applied to everyone, regardless of their medical history.
Potential for Clinical Integration
Despite these limitations, the researchers are hopeful that the heart-aging tool could eventually become part of routine clinical practice. If validated in larger, more diverse populations, the tool could serve as an early detection mechanism, helping doctors identify patients at risk of heart disease before symptoms even appear. By catching potential problems earlier, healthcare providers could take preventive measures that reduce the overall burden of heart disease in the population.
In the future, the heart-aging tool could be integrated into regular health check-ups, enabling doctors to track changes in a patient’s heart age over time. By monitoring changes in functional age, doctors could more easily detect the onset of health problems, providing patients with timely advice and treatment.
A Step Toward Heart Disease Prevention
Heart disease remains one of the leading causes of death globally. According to the World Health Organization (WHO), cardiovascular diseases are responsible for nearly 18 million deaths each year. Given this high toll, researchers and healthcare professionals are continuously looking for ways to prevent heart disease before it happens. The development of this heart-aging tool is an important step forward in that direction.
The tool could have significant benefits for individuals at risk of developing heart disease, particularly those with conditions like diabetes, obesity, and high blood pressure. By providing doctors with a clearer understanding of how fast a person’s heart is ageing, the tool offers an opportunity for more precise and personalized medical interventions.
The heart-aging tool developed by researchers at the University of East Anglia represents a significant advancement in the fight against heart disease. By providing a way to calculate a person’s heart’s “functional age,” this tool could help doctors identify patients at risk of cardiovascular problems and offer more personalized guidance to slow the aging process. While further research is needed to confirm its effectiveness across larger populations, the tool has the potential to improve heart health outcomes and prevent heart disease in the future.
