To explore the efficacy of triflusal in patients with symptomatic peripheral microcirculation dysfunction. Triflusal is a salicylate compound approved in several countries as antithrombotic agent and it additionally has vasodilatory effect. The hypothesis is to explore if there is a improvement of peripheral microcirculation by triflusal.

Primary Outcome Measures:
  • Primary Outcome - The amount of blood flow measured by finger doppler ultrasonography. The improvement of subjective symptom measured by questionaire. [ Time Frame: 6 weeks ]
    Comparison of the PSV (peak systolic velocity) and EDV (end diastolic velocity) measured by finger doppler ultrasonography between disgren and aspirin groups after 6 weeks treatment.
