Hidden Inflammation Harms Hearts Silently
20 Sep
Summary
- Chronic inflammation increases heart attack and stroke risk by 43%.
- Inflammation linked to heart structure changes like thickened walls.
- Social factors and mental health strongly tied to heart inflammation.
Chronic inflammation, fueled by everyday stress, socioeconomic factors, and lifestyle choices, poses a significant, silent threat to heart health. A large UK study revealed individuals with the highest inflammation levels faced a 43% greater risk of heart attack and stroke compared to those with the lowest.
This widespread inflammation is associated with damaging structural alterations in the heart. These include thickening of heart walls, shrinking of chambers, and reduced heart filling capacity, potentially leading to heart failure over time. The research indicates millions may unknowingly harbor this inflammation, slowly causing irreversible damage.
Interestingly, the study found strong links between higher inflammation and socioeconomic disadvantage, psychological distress, smoking, and excess body weight. This suggests chronic inflammation acts as a pathway through which societal pressures and mental health issues elevate cardiovascular risk.
Researchers identified specific inflammatory proteins as likely culprits, with some already targeted by existing drug trials. This opens potential avenues for anti-inflammatory treatments to prevent cardiovascular disease before symptoms manifest. Combining inflammation tests with genetic risk scores could aid early intervention identification.
