The risk of heart attack Just Like a non- smoking former smoker

Each year, hundreds of thousands to millions of people die from smoking-related diseases. Smoking is known to be a bad habit that increases the risk of disease.

But a new study has revealed that the risk of disease who quit smoking will be reduced to the same as those who had never smoked . The study, presented at the European Society of Cardiology by Dr. James K. Min and Dr. Rine Nakanishi it shows the impact of smoking cessation on the risk of cardiovascular disease , coronary heart disease (CHD) , and even death .

The study included 13,372 patients from nine countries in Europe , North America and East Asia . Participants were divided into three groups , 2,853 current smokers, 3,175 former smokers and 7,344 non-smoking.

To assess the prevalence of coronary artery blockages of the three groups , the researchers used a method of coronary CT angiography (CCTA) . The process is an invasive technique to clearly see the coronary arteries.

They found that active smokers , such as former smokers , the risk of one and a half times more likely to have a blockage in one or two major coronary arteries than those who had never smoked . In addition, the major risk of heart arteries blockage was third twice .

According to the website of the Mayo Clinic, arterial obstruction is due to a narrowing of the blood vessels so that capacity is not complete . Aortic blood clots block blood flow from the heart to the aorta and throughout the body .

Blocking is heart work harder to pump blood . If the situation is not checked , the heart muscles weaken and over time lead to serious heart disease .

According to the study , smoking cessation does not diminish the severity of the coronary arteries so that the risk of death is higher than non-smokers . After two years, the researchers found 2.1 percent of the participants had a heart attack or death .

Active smokers have a risk of heart attack and death about two times higher than those who had never smoked . However , former smokers have the same heart rate with those who do not smoke, and do not have a higher prevalence of coronary heart disease as well .

Min said , this study aims to determine the impact of smoking cessation on the risk of cardiovascular disease , death and the severity of coronary artery disease. However, further studies are needed to determine the time period necessary to reduce the risk of disease to the same as non-smokers .

According to the American Cancer Society, ex-smokers the risk of disease are the same as non-smokers stopped smoking after 15 years.
