Journal/Book: Fortschritte der Medizin. 1993; 111(20-21): 352-354.

Abstract: In 30 patients with stage NYHA II cardiac insufficiency, a placebo-controlled randomized double-blind study was carried out to determine the efficacy of the Crataegus special extract WS 1442. Treatment duration was 8 weeks, and the substance was administered at a dose of 1 capsule taken twice a day. The main target parameters were alteration in the pressure-x-rate product (PRP) under standardised loading on a bicycle ergometer, and a score of subjective improvement of complaints elicited by a questionnaire. Secondary parameters were exercise tolerance and the change in heart rate and arterial blood pressure. The active substance group showed a statistically significant advantage over placebo in terms of changes in PRP (at a load of 50 W) and the score, but also in the secondary parameter heart rate. In both groups, systolic and diastolic blood pressure was mildly reduced. No adverse reactions occurred.
