Exposure to secondhand smoke may increase odds of developing heart failure 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 70 th 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.
