| Abstract:
|
The aim of the study was to assess the activity of pre-PCI atorvastatin reload on the acute inflammatory responses
and in Toll-Like Receptor 4 expressions with its downstream signaling. A double-blind randomized prospective study,
30 patients who received low dose atorvastatin 40 mg/day without reload. While, 30 patients who were already on
the usual dose of atorvastatin with further 80 mg & 40 mg at 12 and 2 hrs before PCI respectively. TLR4 expression
in peripheral monocyte investigate by flow cytometry, and cardiac troponin I, CK-MB, HsCRP and HMG-BOX protein
by ELISA technique immediately before and at 4 hrs, 12 hrs. After PCI. Stent implantation was associated with an
elevation in TLR 4 expression in peripheral monocyte of both study groups after stenting with higher expression level
was found among control group (p<0.05) at 4 hr and 12 hr post-PCI. HsCRP, HMGbox1protein were lower in
atorvastatin reload group (p<0.05), and the myocardial injury markers (CKMB, troponin I) were significantly higher
among the control group than atorvastatin reload group (p<0.05). Atorvastatin attenuated toll-like receptor 4
expressions on peripheral monocyte subsequently its downstream effects HsCRP and HMGBOX1-protein.
