Quitting smoking: how long does it take to reduce cardiovascular risks?

To find out, researchers from Ansan Hospital at Korea University (South Korea) used the Korean national health insurance database over a period from 2006 to 2019. That is, data from more than 5 million people. The study followed three distinct groups: active smokers (15.8%), ex-smokers (1.9%) and non-smokers (82.2%).

From 10 to… 25 years old

Result: ex-smokers who smoked a pack a day for less than 8 years experienced a significant reduction in the risk of cardiovascular disease within 10 years, ultimately reaching a level similar to that of non-smokers.

On the other hand, for those who smoked for more than eight years, it was necessary to wait more than 25 years for the residual risk of cardiovascular disease to disappear.

When reading these results, two observations emerge:

1. the importance of stopping smoking early to limit the accumulation of long-term cardiovascular risks. 2. The importance, for health professionals, of considering those who have smoked more than one pack per day for more than 8 years as having a cardiovascular risk equivalent to that of still active smokers. And this for optimal care.
