A study published in Trends in Cardiovascular Medicine shows that smoking—both active and passive—accelerates heart aging in children. Researchers from the U.S., U.K., and Finland highlight that tobacco exposure in childhood and adolescence causes structural and functional heart damage even before clinical symptoms appear.
Children exposed to smoking have a significantly higher risk of heart failure and sudden cardiac death by ages 40–50. Quitting smoking in midlife (e.g., around 30) reduces mortality risk but does not fully eliminate the risk of heart failure later.
The harmful effects are driven by metabolic disturbances, muscle mass loss, and toxin accumulation, worsened by sedentary lifestyles and poor diets. Rising e-cigarette use among adolescents further increases vulnerability to traditional smoking.
Experts emphasize prevention during childhood, promoting physical activity, and limiting access to nicotine products as the most effective strategies to protect current and future generations’ heart health.
