Abstract:
Objective To compare the systemic and local near atherosclerosis lesion levels of proinflammatory factor interleukin-1β (IL-1β) and anti-inflammatory factor IL-10 in patients with coronary artery disease (CAD). Methods Plasma samples were collected from 30 individuals without angiographical coronary artery stenosis (control group), 90 patients with CAD (stable angina pectoris, SA, n = 30,unstable angina pectoris/non-ST-segment elevation myocardial infarction, UA/NSTEMI, n = 30 and ST-segment elevation myocardial infarction, STEMI, n = 30). During diagnostic coronary angiography or interventional procedures, systemic samples were obtained from aorta root in all patients (n = 120), local samples from distal of the coronary lesion in patients with CAD (n = 90), and samples from coronary sinus of 14 patients with STEMI. IL-1β and IL-10 were determined by ELISA method. Results The result showed systemic levels of IL-1β were lg-1 (0. 97 ±0. 42), lg-1 (0. 98 ±0. 43), lg-1 ( 1.21 ±0. 42), lg-1 ( 1.30 ±0. 43)ng/L in the control, SA,UA/NSTEMI and STEMI groups, were significantly higher in UA/NSTEMI and STEMI groups compared with the control group (P < 0. 05, P <0. 01 ); systemic IL-10 levels were lg-1 (0. 77 ± 0. 29), lg - 1 (0. 73 ± 0. 45 ), lg- 1 (0. 75 ± 0. 35 ), lg- 1 ( 1.14 ± 0. 36) ng/L in the four groups and was significantly higher in STEMI group than the control group ( P < 0. 01 ). The local concentration of IL-1β and IL-10 were similar as the systemic levels in SA group [lg-1 (0.98 ±0.41 ), lg-1 (0.67 ±0.47)ng/L], local IL-1β [lg-1 ( 1.22 ±0. 48) ng/L] was similar while local IL-10 [lg-1 (0. 89 ±0. 46) ng/L]was significantly higher than the systemic levels in UA/NSTEMI group. The local levels of IL-1β and IL-10 [lg-1 ( 1.45 ±0. 45), lg-1 ( 1.35 ±0. 31 ) ng/L] were both significantly higher than the systemic levels in STEMI group ( all P < 0. 01 ). The IL-1β levels of systemic, local and coronary sinus in STEMI patients with acute totally occluded left coronary artery [lg-1 ( 1.47 ± 0. 37 ), lg- 1 ( 1.65 ± 0. 34), lg- 1 ( 1.53 ± 0. 35 )ng/L] and the IL-10 levels [lg-1 ( 1.06 ± 0. 48 ), lg- 1 ( 1.34 ± 0. 39 ), lg-1 ( 1.34 ± 0. 23 ) ng/L] were similar. The level of IL-1β in coronary sinus was significantly lower than in culprit lesion (P<0. 05) while IL-10 levels were similar at these two sites ( P > 0. 05 ). Conclusion The systemic level of pro-inflammatory marker IL-I β and anti-inflammatory marker IL-10 could not rehably reflect the local inflammatory status near the atherosclerosis plaque locations.
