Silent Heart Damage Linked to Chronic Inflammation, Study Reveals
- •A large study of nearly 480,000 UK adults found chronic inflammation, driven by stress, socioeconomic disadvantage, and lifestyle, can silently damage the heart years before cardiovascular symptoms appear.
- •Individuals with the highest inflammation levels faced a 43% higher risk of heart attack and stroke compared to those with the lowest levels.
- •Higher inflammation was associated with structural heart changes, including thickened walls, smaller chambers, and poorer filling, which can lead to heart failure.
- •The study highlighted strong links between inflammation and socioeconomic disadvantage, psychological distress, smoking, and excess body fat, suggesting social factors and mental health contribute significantly.
- •Researchers identified inflammatory proteins (interleukin-1 and TNF families) as drivers of heart damage, raising hopes for anti-inflammatory treatments to prevent cardiovascular disease.
Key Questions Answered
A study of nearly 480,000 UK adults revealed that people with the highest levels of inflammation had a 43 per cent higher risk of heart attack and stroke. Higher inflammation was associated with structural heart changes such as thickened heart walls, smaller chambers, and poorer heart filling, which can silently progress for years before causing heart failure.
Chronic inflammation is driven by everyday stress, socioeconomic disadvantage, psychological distress, and lifestyle factors like smoking and excess body fat. The research highlights that social factors and mental health are heavily linked to this inflammation, acting alongside established cardiac risk factors.
The study identified specific inflammatory proteins from the interleukin-1 and TNF families as likely drivers of heart damage. Because several of these proteins are already targeted by drugs in clinical trials, researchers raise the possibility that anti-inflammatory treatments could help prevent cardiovascular disease before symptoms develop.
