Even though we don’t know exactly which smokers will develop CVD from smoking, the best thing all smokers can do for their hearts is to quit. Smokers who quit start to improve their heart health and reduce their risk for CVD immediately. Within a year, the risk of heart attack drops dramatically, and even people who have already had a heart attack can cut their risk of having another if they quit smoking. Within five years of quitting, smokers lower their risk of stroke to about that of a person who has never smoked. However, studies have reported that smoking increases the risk of CVD beyond the effects of smoking on other risk factors. In other words, the risk attributable to smoking persisted even when adjustments were made for differences between persons who smoke and nonsmokers in levels of these other risk factors.
