Figure 1

Microvascular blood flow measured using laser Doppler velocimetry in normal myocardium exposed to topical negative pressures of A) -50 mmHg, and B) -125 mmHg. The measurements were performed in six pigs at a depth of 1–2 mm in the myocardium. Significance was defined as *p < 0.05, **p < 0.01, ***p < 0.001 and p > 0.05 (not significant, n.s.). Values are presented as means ± the standard error on the mean (SEM).
