The use of electronic (e)-cigarettes, or vaping, is a growing phenomenon in the United States but the impact of e-cigarettes on health have not been thoroughly studied, especially in college students. PURPOSE: To examine cardiovascular function of undergraduate Gonzaga University students that engage in chronic e-cigarette use. METHODS: Male and female students (n=8 e-cigarette users, n=8 non-users) were recruited to participate. Anthropometric data was collected and all subjects completed a questionnaire that asked about e-cigarette use and other health habits. All subjects then underwent an electrocardiograph (ECG) and ultrasound imaging of the carotid artery and heart (parasternal (PLAX) and apical five-chamber) at rest. RESULTS: The mean heart rate at rest was lower in non-users (64.63±14.34 bpm) than e-cigarette users (75.50±15.81 bpm, p<0.05). Systolic blood pressure was also higher in in e-cigarette users (123.25±12.60 mmHg) compared to non-users (115.13±7.90 mmHg, p<0.05). Diastolic blood pressure for non-users was significantly lower (69.25±16.37 mmHg) compared to e-cigarette users (78.38±12.16 mmHg, p<0.05). Cardiac output in e-cigarette users (4.15±0.63 L/min) was lower than non-users (5.24±1.32 L/min) but not significant (p>0.05). CONCLUSION: Initial analysis suggests that chronic use of e-cigarettes may negatively impact cardiovascular function in college students, but additional subjects are needed to confirm our observations. Provided the variety of chemicals and different amounts of nicotine used in e-cigarette devices, identifying any single causative agent would be challenging and would require studies that control the specific type and amount of e-cigarette products used by subjects.
