Tobacco product use is associated with impaired endothelial cell (EC) phenotype.

A, Nitric oxide (NO) production (4,5‐diaminofluorescein diacetate [DAF‐2DA] fluorescence) in response to A23187 stimulation in ECs freshly isolated from combustible cigarette users (n=11) and e‐cigarette users (n=5) was lower compared with nontobacco product users (n=10). B, Endothelial NO synthase (eNOS) levels quantified by immunofluorescence in ECs from nontobacco product users (n=11), combustible cigarette users (n=13), and e‐cigarette users (n=12) were similar. Data are expressed as mean±standard error.
