Mean vessels diameters variations between day 1 and days 5–7 in levosimendan treated vs control patients. Quantitative analysis of cerebral arteries diameters in patients who had vessel imaging (CT or angiography) at admission and at days 5–7 in nine levosimendan-treated patients and 18 controls. Vessels narrowing was more pronounced in controls compared to levosimendan-treated patients (P = 0.004)
