An accelerated atherosclerosis, in particular of the coronary arteries, was documented in hypertriglyceridemia. The objective of the present study was to assess the cutaneous dynamic blood flow in hypertriglyceridemia, utilizing the optical noninvasive method of laser Doppler flowmetry. The cutaneous blood flow on the forearms was measured during the postischemic reactive hyperemia test in treated and non-treated patients with hypertriglyceridemia and healthy control subjects. The subjects were 32 patients with hypertriglyceridemia--15 untreated and 17 following 6-9 months of bezafibrate treatment--and 27 healthy control subjects. In untreated patients with hypertriglyceridemia, the peak flow was significantly lower than in both the treated group (p < 0.005) and control group (p < 0.02). Similarly, the area under the response-time curve of the untreated patients with hypertriglyceridemia was smaller (p < 0.01 and p < 0.05, respectively). These parameters were similar in the treated group and the control group. The reaction was faster in the treated group, as compared to the other two groups (p < 0.001). The control group exhibited a longer time to decay than the treated group (p < 0.01). Postischemic reactive hyperemia tests in patients with hypertriglyceridemia reveal cutaneous microcirculatory changes in the forearm. These changes may arise from several mechanisms, including functional abnormalities of the endothelium or vascular smooth muscle, or structural changes in the blood vessels that limit vasodilatation. These changes are reversible, and corrected when reducing the triglyceride levels, but other abnormalities are then present, suggesting a permanent damage. These dynamic measurements of cutaneous blood flow are sensitive indicators of atherogenesis, and can be employed for the evaluation of microvascular involvement and follow-up of patients with hypertriglyceridemia.
