Isolated nonalcoholic fatty liver disease was associated with significantly higher arterial stiffness compared to controls (pulse wave velocity 7.98 vs 7.40 m/s, P < 0.05).

Does nonalcoholic fatty liver disease (NAFLD) increase arterial stiffness and preclinical atherosclerosis in adults aged 30-70 years?
NAFLD is independently associated with increased arterial stiffness, suggesting a direct role in early vascular damage even in the absence of metabolic syndrome.
Absolute Event Rate: 7.98% vs 7.4%
p-value: p=< 0.05
OBJECTIVE: Nonalcoholic fatty liver disease (NAFLD) is a very frequent disease in Western countries. NAFLD shares with metabolic syndrome the same etiologic factors, such as obesity, diabetes, and dyslipidemia, which are also major cardiovascular risk factors. Cardio-GOOSE (Cardio-Gambettola ObservatOry liver Steatosis Estimation) is a population-based cohort study finalized to evaluate the relationship between NAFLD, subclinical vascular damage, and arterial stiffness. METHODS: The study population consisted of 220 participants (123 women), aged between 30 and 70 years, who participated in the GOOSE study. Arterial stiffness was determined by measuring the carotid-femoral pulse wave velocity (PWV) by means of the PulsePen device. Preclinical atherosclerosis was detected by carotid intima-media thickness (IMT) measurement. RESULTS: NAFLD was associated with metabolic syndrome in 48% of cases. IMT values were strongly related to metabolic syndrome factors. No significant differences in IMT were found between controls and patients with isolated NAFLD (0.77 +/- 0.15 mm versus 0.76 +/- 0.14 mm). Conversely, in patients with NAFLD associated with metabolic syndrome, IMT values were significantly higher than in patients with NAFLD alone (0.85 +/- 0.16 mm, P < 0.005). PWV values were significantly lower in controls compared to patients with isolated NAFLD (7.40 +/- 1.47 versus 7.98 +/- 1.51 m/s, P < 0.05) as well as patients with both NAFLD and metabolic syndrome (8.29 +/- 2.2 m/s, P < 0.001). The prevalence in NAFLD was increased in patients with the highest PWV values, and persisted after adjustment for factors determining metabolic syndrome (P < 0.05). CONCLUSIONS: This study has shown a possible independent role of NAFLD in determining arterial stiffness.
Salvi et al. (Thu,) conducted a cohort in Nonalcoholic fatty liver disease (n=220). Nonalcoholic fatty liver disease (NAFLD) vs. Controls (without NAFLD) was evaluated on Carotid-femoral pulse wave velocity (PWV) (p=< 0.05). Isolated nonalcoholic fatty liver disease was associated with significantly higher arterial stiffness compared to controls (pulse wave velocity 7.98 vs 7.40 m/s, P < 0.05).
