Do You Want Your Heart Disease Risk Doubled?

While cigarette smoking can induce numerous medical disorders to smokers themselves, people who are exposed to smokers’ tobacco smoke are also at a high risk of getting similar medical disorders. One of the disorders is heart disease, one of the leading killers in the world.

Researchers from the University College London reported that people who are around smokers and breathe in a lot of smoke are twice as likely to die from heart disease as those who are exposed to lower levels of secondhand smoke. Their study, which covered more than 13,000 people in England and Scotland, was published on June 29, 2010 in the ‘Journal of the American College of Cardiology’.

A saliva test was used to measure the amount of secondhand smoke people have been exposed to and the participants were followed for an average of 8 years, keeping track of who developed heart disease and who died.

It was found that 32 out of about 1,500 people who had never smoked but were exposed to high levels of secondhand smoke died of heart disease. In comparison, only 15 out of about 1,000 people who never smoked but with low exposure. Their analysis, which was restricted to never-smokers only, showed that high secondhand smoke exposure was linked to more than a 2-fold increased risk of dying from heart disease.

High level of exposure, according to the definition set by the researchers, would be equivalent to living with a smoker and exposed to secondhand smoke almost every day.

This is definitely not the first study to reveal such association. In a 10-year study published in 1997 in the journal ‘Circulation’, researchers from the Harvard School of Public Health reported that women who never smoked but regularly exposed to other peoples’ smoking in home or work had their risk of heart disease almost doubled.

More than 32,000 healthy women who never lighted up a cigarette were tracked. These women, aged between 36 and 61 when the study began, suffered 152 heart attacks, 25 of them fatal.

In order to prevent heart disease, smokers are urged to give up this unhealthy and selfish habit for the sake of their loved ones. Meanwhile, people staying with smokers should strive to help them quit smoking so as to lower the risk of heart disease for all in the house.

A Child's Cardiovascular System May Be At Risk By Secondhand Smoke!

Parents may want to consider giving up their smoking habit as this will harm not only their own bodies but also their children's arteries.

A study, conducted by the Research Centre of Applied and Preventive Cardiovascular Medicine at the University of Turku in Finland, measured levels of continine in blood of 400 children between the ages of 8 and 11. Continine is a substance that the body produces when it breaks down nicotine in tobacco smoke. The participants were divided into 3 groups: low, high and non-detectable continine groups.

The researchers reported that exposure, even a little, to secondhand smoke at home or in public can actually harm the function of the cardiovascular system of the healthy children. This is because children who were in the high continine group were found to have a significantly lowered endothelial function. As a measure of arterial health, endothelial function is the blood coagulation and platelet adhesion in the blood vessels.

Parental smoking is also associated with an increased occurrence of asthma and respiratory illness in children. Statistics showed that asthmatic children who are exposed to cigarette smoke at home have a 4.5 times greater risk of respiratory-related absence from school, thus affecting their learning.

Besides cardiovascular disease and asthma, cancer, especially of the lung, is another disease that is strongly associated with secondhand smoke.

Smoking Mothers Could Risk Their Babies Of Heart Disease!

Smoking has long been regarded as a risk factor of heart disease. But now, women who smoke and want to have baby may need to think twice because cigarettes may cause heart defects to their babies.

A report presented at a meeting of the American Heart Association in Chicago revealed that pregnant women who smoke just before pregnant and shortly thereafter may increase the risk of their babies of getting a congenital heart disease by 60 to 80 percent. Exposing to second-hand smoke in the workplace or at home may also raise the women's risk of bearing infants with such defects by 30 percent.

This is the finding provided by a study conducted by the University of Arkansas for Medical Sciences.

Congenital actually means existing at or dating from birth. Congenital heart disease refers to a kind of problem with the heart's structure and function due to abnormal heart development before birth. Congenital heart disease can cause more deaths in the first year of life than any other birth defects. Some of these defects may heal over time, others will need treatment.

The actual causes of most of defects are not known, but scientists believe that genetic susceptibilities and exposure to environmental toxins, such as alcohol, infections, various chemicals and some medications, may be the culprits.

Cigarette smoke contains about 3,000 chemicals and sad to say, their potential to cause heart defects is still unclear till now.

The heart's basic structure develops early in pregnancy. During this period, chemicals or infections may easily interfere with the genetic blueprint resulting in abnormalities. Even if pregnant women stop smoking 6 weeks after conception, the foetus can still be exposed to the chemicals in cigarette smoke. The most common problem caused is ventricular septal defect, which is a hole between 2 chambers of the heart.

It is estimated that some 2,000 congenital heart defects could be prevented every year if women stopped smoking before they try to become pregnant. Or better still, do not start smoking at all and this could be good not only for you but also to the people around you!
