title: [Dipyridamole (curantil) treatment of anginal patients: results of treatment for many years].
abstract: OBJECTIVE
  To assess effect of curantil optimal doses on clinical condition, coronary reserves, systemic microcirculation and peripheral hemodynamics in patients with stable angina pectoris (AP) given a course or continuous treatment.
  
  
  METHODS
  A 2-month treatment with curantil with a gradual increase of the daily dose to 0.45 g was given to 261 patients with AP. After that the treatment was continued to 3 years in 38 patients. The coronary reserves were examined with bicycle exercise tests, peripheral hemodynamics and microcirculation were investigated with tachooscillography and conjunctival biomicroscopy.
  
  
  RESULTS
  The 2-month curantil treatment was effective in 81% of the patients with AP functional class II-III and 60% of those with AP class 4. Exercise tolerance increased in AP of functional class II-III and IV by 50 and 24%, respectively. Ischemic depression of ECG ST segment induced by the exercise shortened. Prolongation of the treatment to 1 year resulted in further regression of AP and provided a 57% increase in muscular performance. The 3-year treatment maintained the 1-year effectiveness which was associated with lowering of postload and improvement of microcirculation, in particular, a 2-fold decrease in manifestations of sludge.
  
  
  CONCLUSIONS
  The antianginal effect of optimal daily doses of curantil is more potent in angina of effort, grows step-by-step and reaches maximum if continued for a year. A hemodynamic effect of curantil manifests with lowering of postload and improvement of microcirculation. This allows to recommend curantil in combined treatment of chronic coronary heart disease.
