Early heart habits at 25 determine lifelong risks, 40-year study reveals

A 40-year study has revealed how early heart health habits shape long-term risks of heart attack and stroke. Researchers identified four distinct patterns of cardiovascular health, with most trajectories set by age 25. The findings highlight why building healthy routines in young adulthood can prevent serious issues decades later.

The study tracked participants over four decades and found that heart health followed one of four paths: persistent high, persistent moderate, moderate declining, or moderate/low declining. Those with good cardiovascular health in their mid-20s were far more likely to maintain it over time. In contrast, poor heart health at that age increased the risk of later disease by tenfold.

Once established, these trajectories proved difficult to alter. While later lifestyle changes still offered some protection, early intervention provided the strongest benefits. The worse a person's heart health path, the higher their chances of future cardiovascular events.

Experts recommend regular check-ups with a GP to monitor blood pressure and cholesterol. Counselling on diet, exercise, and quitting smoking was also advised. The public can assess their own risks using the Life's Essential 8 scoring system, which outlines key factors for maintaining heart health.

The research confirms that habits formed in young adulthood play a critical role in lifelong heart health. Early education and preventive measures remain the most effective ways to reduce cardiovascular risks. However, improvements at any age can still lower the likelihood of heart attacks and strokes.
