A simple £5 blood test could help doctors identify hidden heart damage and potentially prevent strokes and heart attacks, according to new research. By measuring troponin levels, which indicate heart muscle stress, doctors can better predict long-term cardiovascular risks in individuals, even if they are not showing symptoms of heart problems. This test may become a vital tool during routine check-ups, alongside common tests like cholesterol screenings, offering a proactive approach to heart health.

Troponin Reveals Hidden Heart Stress

Troponin is a protein released when the heart muscle experiences damage, making it a key marker in diagnosing heart attacks. Hospitals currently use it to confirm heart attacks. However, a recent study has shown that troponin can also detect early heart damage, even in individuals who feel otherwise healthy.

The significance of this discovery lies in its potential to spot hidden heart stress before it leads to more severe cardiovascular events. By including troponin tests in regular health check-ups, doctors could identify heart damage in its early stages, offering an opportunity for timely intervention.

Boosting Risk Prediction

Researchers conducted an extensive study involving 62,000 people across Europe and the United States, spanning a decade. The study compared troponin levels with traditional risk factors such as age, cholesterol levels, and blood pressure.

The addition of troponin data significantly improved risk predictions, making them up to four times more accurate compared to using cholesterol alone. This was particularly beneficial for individuals in the intermediate-risk group—those not typically considered at high risk for heart disease based on traditional markers.

In fact, the test reclassified 8% of these individuals as high-risk. By identifying these patients earlier, doctors could provide preventive treatments, such as statins, which could help avoid thousands of strokes and heart attacks.

A Game-Changer for Prevention

Professor Anoop Shah, the lead researcher of the study, highlights that the test offers “powerful extra information” to help improve cardiovascular disease prevention. His comments are echoed by Professor Bryan Williams from the British Heart Foundation (BHF), who calls the test a “real opportunity” to reduce hospital admissions for heart attacks and strokes.

The affordability of the test further emphasizes its potential. Priced at just £5, this test could be accessible to millions, helping doctors identify at-risk individuals and provide them with early treatment. The result could be a significant reduction in the prevalence of heart disease, improving long-term heart health across populations.

The introduction of a simple and affordable troponin test represents a major leap forward in cardiovascular disease prevention. By detecting hidden heart stress and improving risk predictions, doctors can offer earlier, more effective treatments that could save lives. As this test becomes more widely available, it could change the way heart disease is managed, ultimately preventing thousands of heart attacks and strokes.
