IM - COMMENTARY

Smoking is a major risk factor for the development of cardiovascular disease (CVD), and is responsible for 10% of all CVD cases [1]. Cigarette smoke exposure (CSE) causes endothelial dysfunction [2] through an increase in oxidative stress, with effects on endothelial cell structure and function [3]. In fact, accumulating evidence suggests that oxidative stress and inflammation provide the pathophysiological link between cigarette smoking and CVD [2, 3, 4, 5]. Oxidative stress, defined as an imbalance between reactive oxygen species (ROS) production and antioxidant defenses, elicits toxic effects on all cellular components, including proteins, lipids, and DNA [6, 7, 8, 9, 10, 11]. Increased ROS generation by vascular and inflammatory cells occurs in cardiovascular disease, and there is widespread evidence that oxidative injury contributes to vascular damage and cardiac dysfunction [12]. In line with this, elevated levels of oxidative stress biomarkers have been found in the circulation...
