After switching to electronic cigarette, the deterioration of COPD patients was reduced by 50%


Recently, a paper published in the well-known journal progress in the treatment of chronic diseases has attracted the attention of the medical community. It is pointed out that smoking will further worsen the symptoms of patients with chronic obstructive pulmonary disease (COPD). If it is really impossible to quit smoking, switching to electronic cigarettes can reduce the deterioration of the disease by about 50%, and this health improvement can be maintained for a long time.

Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by cough, chest tightness, shortness of breath and poor breathing. If we do not pay attention to it, the disease will further develop into cor pulmonale or respiratory failure, and the disability rate and mortality rate are very high.

The study was led by scholars from coehar, University of Catania, Italy. The paper shows that for COPD patients, if they continue to be exposed to cigarette smoke, the probability of respiratory infection and symptom deterioration will be greatly increased. Quitting smoking is the primary task to improve the disease. However, the reality is that most patients have the problem of quitting smoking, so it is a very practical method to use e-cigarettes to reduce harm.

The clinical observation cycle of this study lasted 60 months, which was the longest in similar studies in the past. Finally, 39 COPD patients provided complete data, of which 20 were smokers and later switched to electronic cigarettes. The researchers collected the relevant data of these 20 patients before switching to electronic cigarettes and compared them with the follow-up data of 60 months. In order to ensure the objectivity of the study, the researchers also selected 19 patients who only used cigarettes as the control group and comprehensively evaluated their respiratory deterioration, vital capacity index and quality of life.

Research data show that in the group of e-cigarette users, 9 people successfully quit smoking after switching to e-cigarette, and the remaining 11 people did not completely quit smoking, but the amount of smoking also decreased significantly. The exacerbation of COPD in these patients was reduced by about 50%, and there were significant continuous improvements in lung function, respiratory health and physical activity. However, smokers have no significant changes in these aspects.

Another important finding of the study is that only 2 COPD patients in the e-cigarette group relapsed into cigarettes during the five-year study period. The author points out that this is because e-cigarette simulates the smoking process and related experience, which can effectively prevent relapse, which is also an important mechanism for e-cigarette to help quit smoking for a long time.

The report also cites the data of a large-scale study of 1190 CODP patients in the United States from 2014 to 2015. The study found that 75.7% of patients said that their respiratory symptoms improved after switching to e-cigarettes, and many patients are using e-cigarettes to avoid relapse.

In the paper, the author emphasizes that this study is more valuable because many patients with COPD are still reluctant to quit smoking even if they have obvious symptoms. Doctors can suggest that these patients choose relatively less harmful e-cigarettes as substitutes, so as to reduce the pain of quitting smoking and illness. After all, after scientific confirmation, e-cigarettes can reduce the harm by 95% compared with cigarettes.
