* Key Point Gender-specific smoking prevalence varies across the world. Background Worldwide, there are marked differences in smoking prevalence rates between men and women from country to country. For example, in South Africa, the Philippines, China, Iran, and Portugal, smoking prevalence is much lower in women than in men. In contrast, in the United States, Canada, Australia, and Iceland, the prevalence of smoking in men is only slightly higher than that in women.1 Overall, the prevalence of smoking in men is declining. However, although smoking prevalence in women is declining in some countries, such as the United States, the United Kingdom, Australia, and Canada, in several southern, central, and eastern European countries, the rate of smoking in women is not in decline or is still increasing.1 Reference 1.

Potential mechanisms by which smoking may play a role in cardiovascular events prior to the development of significant coronary artery disease (CAD) include induction of endothelial dysfunction, oxidative stress, increased blood thrombogenicity, and an enhanced inflammatory response.
