title: [Effect of fenofibrate on fibrinogen concentration and blood viscosity. Consequences for myocardial microcirculation in coronary heart disease?].
abstract: The effect of fenofibrate (a clofibrate derivative) on fibrinogen concentration, blood viscosity and myocardial microcirculation was examined in 35 patients with coronary heart disease (n = 27) or hypertension (n = 8). After eight weeks' administration of 250 mg fenofibrate daily cholesterol and triglycerides levels decreased significantly, as did the fibrinogen concentration, from a mean of 300.7 +/- 75.1 mg/dl to 252.3 +/- 61.2 mg/dl (P less than 0.01). Plasma viscosity and erythrocyte aggregation were also significantly lowered (from 1.43 +/- 0.09 to 1.37 +/- 0.07 mPas and 15.0 +/- 3.1 to 13.5 +/- 2.2, respectively; P less than 0.01). In eight of twelve subjects selected from the whole group thallium myocardial scintigraphy demonstrated, after eight weeks of treatment with fenofibrate, a global (in two) or regional (in six) increase in blood flow. Reduction of fibrinogen concentration may in coronary heart disease achieve an improvement in myocardial microcirculation with decreased myocardial ischaemia.
