Smoking ups heart failure risk
Smoking is associated with thicker heart walls and reduction in the heart’s pumping ability — two factors linked to increased risk of heart failure, a new study warns.

That smoking is bad for heart has been known for long but the new study, in the American Heart Association’s journal Circulation: Cardiovascular Imagin, reveals a clear mechanism by which tobacco may increase the risk of heart failure.”These data suggest that smoking can independently lead to thickening of the heart and worsening of heart function, which may lead to a higher risk for heart failure, even in people who don’t have heart attacks,” said lead author of the study Wilson Nadruz Jr from Brigham and Women’s Hospital in Boston, Massachusetts.
