Key result
Smoking a single cigarette significantly decreased the pulsatility index, resistivity index, and flow velocity of the common carotid artery in healthy nonsmokers, while flow volume and diameter remained unaltered.

Acute CCA hemodynamic shifts after one cigarette signal vascular sensitivity in nonsmokers; leaves open clinical relevance and need for confirmatory studies.
Observational (n=16)
Does smoking a single cigarette alter common carotid artery hemodynamics in healthy nonsmokers?
Absolute Event Rate: 464% vs 459%
p-value: p=0.2
Acute cigarette smoking in healthy nonsmokers significantly alters common carotid artery hemodynamics, decreasing pulsatility and resistivity indices, likely due to enhanced adrenergic activity.
Barutçu et al. (2004) conducted an observational in Healthy nonsmokers (n=16). Smoking a single cigarette vs. Baseline (before smoking) was evaluated on Right common carotid artery flow volume (ml/min) (p=0.2). Smoking a single cigarette significantly decreased the pulsatility index, resistivity index, and flow velocity of the common carotid artery in healthy nonsmokers, while flow volume and diameter remained unaltered.
