Typical e‐cigarette design. E‐cigarettes are usually composed of nicotine cartridge (e‐liquid container), vaporizing chamber, a heating coil (heats e‐liquid) followed by an atomizer (e‐vapor generator), rechargeable battery and voltage controller (which will adjust the amount of nicotine delivered during vaping), microcompressor, and LED indicator—not present in all types—to activate the battery and visually mimic the conventional cigarette, respectively. LED indicates light‐emitting diode.

Effects of acrolein on the cardiovascular system. Wide ranges of cardiovascular effects of acrolein inhalation from smoking and ambient air pollution are reported in animal studies.138, 139, 142, 146

Figure 3
Effects of particulate matter (PM2.5) on the cardiovascular system. PM2.5 exposure from tobacco and environment/ambient negatively affects the cardiovascular system either directly or indirectly. The direct pathway is mediated by the delivery of PM2.5 into the bloodstream. The indirect pathway is attributed to deposition of PM2.5 in lungs and a modulation of autonomic nervous system. Oxidative stress is triggered by both pathways and induces local and systemic inflammatory processes. PM2.5 indicates particulate matter less than 2.5 microns in diameter.
