title: [Longterm potassium therapy in angina pectoris (author's transl)].
abstract: The effect of a two month potassium therapy on maximum performance was systematically investigated in 12 patients with overt angina pectoris. The patients received 40 mEq potassium daily by mouth. The average maximum performance increased by 85% after 8 weeks' administration of potassium. The rise in the performance curve fell after 6 weeks to attain a steady state after 8 weeks. In particular it must be emphasized that the heart rate was reduced under maximum capacity in spite of considerable increase in performance. Furthermore, a comparison of heart rates after 8 weeks' potassium administration showed that in each case for the same level of performance the heart rate was 15% less than before potassium. The results of the investigation support longterm therapy with potassium in angina pectoris.
