Valsartan versus ACE inhibition after bare metal stent implantation-results of the VALVACE trial

The administration of 80 mg valsartan after bare metal stent implantation leads to a reduction of in-stent-restenosis compared to ACE-i. This effect is mainly due to beneficial effects of valsartan in cases with initial ACS. Major differences between ACE-i and valsartan are discussed including inflammation, activation of neutrophils, mode of bradykinin activation, AT2 receptor stimulation and apoptosis of smooth muscle cells.
