Identification of Biomarkers in Subjects With Coronary Syndrome (PLAQUE Study)

Study Overview
=================
Brief Summary
-----------------
The study will to test the levels of innovative biomarkers, such as miRNAs, in the blood of subjects underwent to angioplasty procedure according to standard clinical practice.

Detailed Description
-----------------
Twenty patients with acute coronary syndrome from non-ST-segment elevation myocardial infarction or with chronic coronary syndrome with clinical indication and favorable anatomy for coronary angioplasty will be enrolled. The angioplasty procedure will be performed according to standard clinical practice. Before and after angioplasty, blood samples will be taken upstream and downstream of the coronary lesion, arterial sampling will be performed at the level of the aortic root, and peripheral venous blood will be collected. MicroRNA expression will be analyzed in serum by next-generation sequencing (miRNome). Quantitative analysis of pro- and anti-inflammatory molecules such as IL-6 and the soluble form of IL-33 receptor (sST2) will be performed on various blood samples.
