Key result
Acute tobacco cigarette smoking increased blood pressure significantly more than acute electronic cigarette use, despite similar increases in plasma nicotine.
Why the study?
Does electronic cigarette use have different acute and chronic sympathomimetic effects compared to tobacco cigarette smoking?
Observational
Does electronic cigarette use have different acute and chronic sympathomimetic effects compared to tobacco cigarette smoking?
While both e-cigarettes and tobacco cigarettes increase sympathetic nerve activity, tobacco cigarettes cause a significantly greater acute increase in blood pressure, likely due to combusted non-nicotine constituents.
May indicate greater acute BP effects from tobacco than e-cigarettes; leaves open mechanisms and long-term implications.
Chronic electronic cigarette (EC) users and tobacco cigarette (TC) smokers exhibit a similar level of sympathetic nerve activity as estimated by heart rate variability. Acute increases in blood pressure (BP) and heart rate in EC users are attribute to nicotine, not non-nicotine, constituents in EC aerosol. Acute TC smoking increased BP significantly more than acute EC use, despite similar increases in plasma nicotine, suggestive of additional adverse vascular effects attributable to combusted, non-nicotine constituents in TC smoke.

Arastoo et al. (2020) conducted an observational in Electronic cigarette and tobacco cigarette use. Electronic cigarette (EC) use vs. Tobacco cigarette (TC) smoking was evaluated on Blood pressure and heart rate. Acute tobacco cigarette smoking increased blood pressure significantly more than acute electronic cigarette use, despite similar increases in plasma nicotine.
