You probably know that passive smoking is harmful for you, but do you know how much? Secondhand smoking increases a non-smoker’s risk of heart disease by 25 to 30 percent. Not all heart patients know that secondhand smoke is bad for them—and not all doctors are asking them if they live with a smoker, according to a new study.

Co-author Dr Nancy A Rigotti, from the Massachusetts General Hospital, states that doctors have not been trained to ask patients routinely about exposure to passive smoking. Reasons for this could be a lack of prompt or lack of some place to record the answer in electronic medical records.

Coronary Heart Disease (CHD), in which plaque builds up inside the arteries supplying blood to the heart, is the most common type of heart disease and kills about 380,000 people in the US each year, according to the Centers for Disease Control and Prevention.

Dr R William Vandivier from the University of Colorado stated that even though both patients and doctors know the bad effects of passive smoking, it is not being addressed. He believes that if a doctor spends three minutes counseling a patient about the harmful effects of passive smoking, it can lead to patients changing their behavior.

According to Rigotti, smokers should be encourage to quit and smoking should never take place in an enclosed area.

Stay away from passive smoking—it will save your heart.
