Using data from 121,317 participants in the U.K. Biobank, the study assessed well-being through key areas such as family relationships, friendships, health, and financial stability. The researchers examined how these factors related to four major types of cardiovascular diseases.
The findings revealed that individuals with higher well-being exhibited a significantly reduced risk of developing CVDs. The participants were categorized into four distinct well-being groups: low, variable, moderate-to-high, and high satisfaction. Across these categories, those reporting greater satisfaction generally faced a lower risk of heart-related issues.
The study also explored potential causal links between well-being and reduced CVD risk using Mendelian randomization, a method that assesses genetic influences. According to the researchers, people with higher well-being tended to engage in healthier behaviors and exhibited lower levels of inflammatory markers—factors that partly explained the reduced risk of cardiovascular disease.
The authors highlight that promoting well-being could be an effective strategy for reducing the incidence of cardiovascular and cerebrovascular diseases. They also suggest that further exploration of biological indicators linking well-being and CVD may offer new insights into the disease's underlying causes.
"Enhancing well-being could lead to a reduced incidence of cardiovascular and cerebrovascular diseases, warranting focused prevention trials," the authors concluded, encouraging further research into the connection between mental health and heart disease prevention.
