Figure 1: Coronary Myogenic Tone Before and After Cardioplegia / Cardiopulmonary Bypass.

Figure 1:

Coronary arteriolar normalized diameter response to intraluminal pressure (20 – 120 mmHg) in patients with no hypertension (NH, n=5), well-controlled hypertension (WC, n=8), and uncontrolled hypertension (UC, n=10) (A) before (pre-) cardioplegia/cardiopulmonary bypass (CP/CPB), and (B) after (post-) CP/CPB. Data also presented as pre- and post-CP/CPB responses subdivided by patients with (C) no hypertension (NH), (D) well-controlled hypertension (WC), and (E) uncontrolled hypertension (UC). Data plotted as mean ± SD; * p < 0.05 UC vs. WC and UC vs. NH; ** p < 0.05 UC vs WC.
