Secondhand smoke linked to higher odds of heart failure


News Release 5-May-2021
Findings call attention to need for more education and stringent smoke-free policies, especially for vulnerable populations
American College of Cardiology


Breathing in secondhand cigarette smoke may leave you more vulnerable to heart failure, a condition where the heart isn't pumping as well as it should and has a hard time meeting the body's needs, according to a study being presented at the American College of Cardiology's 70th Annual Scientific Session.

The data showed that nonsmokers with recent exposure to secondhand smoke had a 35% increased odds of developing heart failure compared with those who hadn't been around tobacco. The association between tobacco exposure and heart failure remained, even after controlling for other factors known to heighten the risk for heart failure such as a history of other heart conditions, high cholesterol and diabetes.

While previous studies have demonstrated the impact of secondhand smoke exposure on people with existing heart failure--for example, on outcomes such as mortality, quality of life and exercise tolerance--this is the first to show an association between tobacco exposure and developing heart failure.
