Millions of Britons are unknowingly living with a silent, progressive disease that dramatically increases their risk of heart failure, according to groundbreaking new research.
A major study has revealed that aortic stenosis, a condition where the heart's aortic valve narrows and restricts blood flow, more than doubles an individual's likelihood of developing heart failure—even before symptoms appear.
The Hidden Epidemic Affecting British Hearts
Researchers analysed data from over 700,000 UK patients, uncovering that those with aortic stenosis faced a 2.3 times higher risk of heart failure compared to those without the condition. The study, published in the Journal of the American Medical Association, followed participants for approximately twelve years.
What makes this condition particularly dangerous is its stealthy nature. Many patients experience no symptoms until the disease reaches an advanced stage, meaning thousands could be at risk without realisation.
Who Is Most at Risk?
The research identified key factors that increase vulnerability:
- Age: The condition predominantly affects those over 60
- High blood pressure
- Existing heart conditions
- Diabetes
- High cholesterol levels
Professor Nick Townsend, a cardiovascular health expert, emphasised: "This isn't just a concern for the elderly. We're seeing earlier onset in some patients with risk factors."
Recognising the Subtle Signs
While often asymptomatic, some individuals might experience:
- Shortness of breath during physical activity
- Chest pain or tightness
- Fatigue and dizziness
- Heart palpitations
- Fainting spells
Medical professionals urge anyone experiencing these symptoms, particularly with known risk factors, to seek medical evaluation.
A Call for Increased Awareness and Screening
The British Heart Foundation has responded to these findings by calling for greater awareness among both the public and healthcare providers. Early detection through stethoscope examination can identify the characteristic heart murmur associated with the condition.
Treatment options have advanced significantly, ranging from medication to manage symptoms to surgical interventions like transcatheter aortic valve implantation (TAVI), a minimally invasive procedure that replaces the damaged valve.
With heart failure affecting approximately 920,000 people in the UK, this research highlights the critical importance of regular heart health checks, especially for those in higher-risk categories.
