Key result
Combined inhaled nicotine and high-fat diet induces LV diastolic dysfunction in mice versus either alone.
Why the study?
Nicotine product usage and high-fat diet consumption are modifiable risk factors for cardiovascular disease, but the cardiovascular effects of their combined exposure remained to be evaluated.

Does not support changes in clinical nicotine or diet guidance; leaves open synergistic human cardiovascular effects.
Nicotine product usage and high-fat diet consumption are two modifiable risk factors for cardiovascular diseases. Here, we demonstrate that in mice, combined exposure to inhaled nicotine and high-fat diet results in unique cardiovascular consequences compared with either treatment alone, including left ventricular diastolic dysfunction, dysregulation of blood pressure, autonomic dysfunction, and greater impairment of endothelium-dependent vasorelaxation. These findings indicate that individuals who consume both nicotine products and high-fat diet have distinctive cardiovascular risks.

Whitehead et al. (2023) studied Cardiovascular dysfunction. Combined exposure to inhaled nicotine and high-fat diet vs. Either treatment alone was evaluated on Cardiovascular consequences including left ventricular diastolic dysfunction, dysregulation of blood pressure, autonomic dysfunction, and impairment of endothelium-dependent vasorelaxation. Combined exposure to inhaled nicotine and high-fat diet in mice resulted in unique cardiovascular consequences, including left ventricular diastolic dysfunction, compared with either treatment alone.
