Sneaking cigarettes might seem like a harmless pre-teen rite of passage, but it’s more dangerous than you think, a new study warns. Regular smoking at a young age doesn’t just lead to a higher chance of smoking later in life — it can also cause serious harm to young hearts. Experts have understood that children who smoked earlier in life were more likely to continue the habit, and the risks that come with it, later into their lives. Now, the new study gives a better idea of the damage it does early on. “Teen smoking doesn’t just increase the risk of heart disease later in life — it causes early and lasting damage to heart muscle and function,” said Dr. Emily Bucholz, an assistant professor of pediatrics at the University of Colorado School of Medicine. Until now, there wasn’t a lot of data on cardiac structure and function in healthy children, since assessing the hearts of healthy young people is uncommon. Overall, persistent smoking from childhood to young adulthood was associated with an over 50% increased risk of premature heart damage, the study, published Dec. 11 in the Journal of the American College of Cardiology (JACC), showed. The damage, such as an enlarged heart or increased pressure in blood flow to the heart, was evident by the age of 24. This analysis followed more than… read on > read on >
