Silent threat may raise heart attack risk
A study published in the European Journal of Preventive Cardiology revealed that ongoing daily stress leads to chronic low-grade inflammation, which causes structural changes in the heart and increases the risk of heart attacks and strokes. Researchers from Imperial College London analyzed data from 488,000 people in the United Kingdom, and the results showed that higher levels of inflammation were associated with smaller heart chamber sizes, thicker heart walls, and a reduced amount of blood pumped with each heartbeat—factors that may precede heart failure. The study also found that individuals with the highest inflammation levels were 43% more likely to experience major cardiovascular events compared to those with lower inflammation levels. The findings indicated that inflammation results from factors such as psychological stress, poverty, and pollution, and that genetic predisposition can influence how severely individuals are affected. Although the study does not establish a direct causal relationship, the results suggest that reducing psychological stress, quitting smoking, and improving lifestyle habits can help lower the risks of heart diseases linked to chronic inflammation.
