Abstract

The haemodynamic and haemorheological effects of buflomedil after acute intravenous infusion and after chronic treatment were studied in 25 patients with occlusive arterial diseases of the lower limbs. Acute treatment (100 mg) induced an increase in ankle blood pressure and in peripheral blood velocity, mainly of the continuous flow, as well as a significant decrease in blood viscosity and a significant increase (p less than 0.01) in red cell deformability, expressed as erythrocyte filtration flow. Chronic treatment (200 mg/day for 20 days) showed haemodynamic and haemorheological effects similar to those of the acute infusion, with a highly significant increase (p less than 0.001) in the erythrocyte flow at the end of the treatment period.

3. Haemodynamic and haemorheological effects of buflomedil in patients with peripheral occlusive arterial disease

Author

Perego, M. A., Sergio, G., Espureo, M., Francisci, A., and Artale, F.

Abstract

SummaryThe haemodynamic and haemorheological effects of buflomedil after acute intravenous infusion and after chronic treatment were studied in 25 patients with occlusive arterial diseases of the lower limbs. Acute treatment (100 mg) induced an increase in ankle blood pressure and in peripheral blood velocity, mainly of the continuous flow, as well as a significant decrease in blood viscosity and a significant increase (p<0.01) in red cell deformability, expressed as erythrocyte filtration flow. Chronic treatment (200 mg/ day for 20 days) showed haemodynamic and haemorheological effects similar to those of the acute infusion, with a highly significant increase (p<0.001) in the erythrocyte flow at the end of the treatment period.

Abstract

A population of 123 patients with recent-onset (< 72 hours) atrial fibrillation (AF) without heart failure was randomly treated with propafenone (PFN) intravenously (i.v.) (2 mg/kg bolus followed by 0.0078 mg/kg/min infusion) or in a single oral dose (o.s.) (600 mg), or with placebo (PLA) (phase 1). If AF persisted 8 hours later, patients on active drugs received the alternative formulation (crossover), and patients receiving PLA remained on PLA (phase 2). A 24-hour Holter monitoring was performed and conversion to sinus rhythm (SR) at 1, 4, and 8 hours of each phase was used as the criterion of efficacy. Conversion to SR occurred within 1 hour in 48% of patients with i.v.-PFN, 15% with o.s.-PFN, and in 17% with PLA (both P < 0.05 vs i.v.-PFN). Oral PFN was superior to PLA at 4 hours (71% vs 33%, P = 0.001) and 8 hours (78% vs 48%, P < 0.01), and 1 at 8 hours also superior to i.v.-PFN (53%, P < 0.03). The mean conversion time within 4 hours was shorter with i.v.-PFN (25 +/- 15') than with o.s.-PFN (167 +/- 166', P < 0.001) or with PLA (156 +/- 107', P < 0.001). The rates of conversion to SR with i.v.-PFN after o.s.-PFN failure were comparable to PLA at any observation time, whereas nonresponders to i.v.-PFN who received o.s.-PFN had significantly higher conversion rates than with placebo at both 4 hours (65% vs 19%) and 8 hours (76% vs 24%; both P < 0.045). Neither serious adverse effects nor episodes of regular tachycardia with 1:1 AV conduction were noted. PFN administered intravenously or in a single oral loading dose was safe and efficacious in converting recent-onset AF to SR. The rates of conversion were different with different routes of administration: i.v.-PFN was superior to o.s.-PFN over a short observation period, while the overall efficacy of o.s.-PFN was superior at 8 hours.

5. [Statistical study on the effect of erythrocyte aggregation on blood filterability].

Abstract

The values of erythrocyte aggregation (expressed as erythrocyte sedimentation rate corrected for plasma viscosity and hematocrit) were correlated with the values of blood filterability in a group of 165 healthy subjects and patients suffering for the most part from vascular disorders. A highly significant inverse correlation (r = -0.57, p less than 0.001) was observed between the two parameters, being a lower blood filterability correlated with a higher erythrocyte aggregation.
