Abstract
Exercise capacity is correlated with overall cardiac beta receptors density, but effects of ß blockers on exercise ability and capacity in elderly patients with HF remains unclear. In present study we estimated the impact of ß blockers therapy on cardiopulmonary functional capacity and LV function in elderly patients with HF. Methods: Thirty consecutive patients aged over 65 with clinical existence of systolic HF treated with ß blockers during 8 weeks. All patients were in NYHA class II-III. Cardiopulmonary exercise testing (CPET) were performed according to a submaximal test protocol before therapy and after 12 week follow up.
