Atherosclerosis is associated with various cardiovascular diseases (CVDs). Measurement of arterial stiffness using pulse wave velocity (PWV) enables assessment of atherosclerosis progression in individuals. The authors screened patients with asymptomatic atherosclerosis, based on the PWV findings, to evaluate appropriate early interventions and assess the efficacy of γ-linolenic acid, Vitis vinifera extract, and acetyl-L-carnitine triple combination therapy in atherosclerosis prevention. This retrospective study analyzed the medical records of adult patients between March 2007 and April 2019, with presenting complaints of fatigue and lethargy. Among patients with vascular stiffness beyond their biological age on brachial-ankle PWV (baPWV) testing, those with ≥80% compliance for three drugs were allocated to the experimental group. Those with compliance of <80% for any one drug were allocated to the control group to assess changes in arterial stiffness, fasting plasma glucose (FPG), lipid level, and blood pressure (BP). After 1 year of triple-combination therapy, there were significant decreases in right and left baPWV (1537.16 ± 274.84 and 1519.00 ± 289.32 cm/s, respectively) as compared to baseline (1633.15 ± 271. 20 and 1598.64 ± 267.95 cm/s, respectively; p < .001). There was no difference in baPWV between sexes. Moreover, neither group showed significant changes in FPG and lipid levels. When triple-combination therapy combining γ-linolenic acid, V. vinifera extract, and acetyl-L-carnitine was administered to patients with high arterial stiffness relative to their age, as assessed by baPWV, the experimental group showed a decrease in arterial stiffness in both sexes.
