(a) Movat pentachrome-stained cross sections of representative coronary and peripheral arteries 3 days, 7 days and 28 days post injury treated with uncoated balloon catheters. Blue: Ground substance and degenerated tissue; red: Muscle; bright red: Fibrin; black: Elastic fiber. Bar = 1 mm. Arrowheads indicate severe injury with media rupture and dissection. (b) Injury score of peripheral and coronary arteries; n ≥ 22 coronary; n ≥ 15 peripheral. (c) Histological and morphometric analyses of Movat pentachrome-stained vessel sections. One cross section each from three section levels per vessel were analyzed. I + M: Intima–media area. rsv: resveratrol. n ≥ 4 peripheral; n ≥ 5 coronary; n: Number of arteries; values are mean ± SD; p-value determined by Mann–Whitney test; * p ≤ 0.05.
