New Delhi, November 3 (IANS) There is a specific dose-related relationship between smoking and cardiovascular disease (CVD). According to a study, light ex-smokers have a higher CVD risk than non-smokers.
The study, published in the journal JAMA Network Open, says that heavy ex-smokers may take more than 25 years to reach the status of never smokers.
The study tried to answer the question: how long does a person need to quit smoking to reduce cardiovascular disease (CVD) risk?
More than 5.3 million participants participated in the cohort study of data extracted from the Korean National Health Insurance Service database, among former smokers who had smoked for less than 8 pack-years, among those who had never smoked. The risk of CVD did not appear to be significantly higher compared to those who did not.
The findings showed that ex smokers (those who had earned at least 8 PY) needed more than 25 years to get rid of the CVD risk of smoking.
According to the authors, the results suggest that ex-smokers (those who have quit smoking) with at least 8 PY should be considered at similar CVD risk as current smokers, and management should be planned accordingly.
The study evaluated the relationship between CVD risk according to smoking cessation, lifetime smoking burden, and the number of years elapsed since smoking cessation.
“These results have important implications for clinical practice and public health,” the authors said. “Regardless of smoking cessation status, smoking and CVD risk demonstrate a clear dose-response relationship, which is not entirely dependent on smoking initiation.” Emphasizes the importance of preventing
People who start smoking can quit if their total smoking amount does not exceed a certain threshold or so-called return point (8 PY in this study) and can expect significant clinical improvement soon after quitting. Can.
Thus, the results suggest that quitting smoking before reaching 8 PY can have significant health benefits.
