Clinical Trial Summary

Subclinical inflammation plays a critical role in all stages of the atherosclerotic process, from the initiation of the fatty streaks to the development of plaque instability and rupture, causing myocardial ischemia and acute coronary syndromes (ACS). A few studies have suggested that the autonomic nervous system (ANS) and the inflammatory response are intimately linked. Accordingly, a relation between impaired cardiac autonomic tone and increased markers of inflammation has been reported in healthy subjects as well as in patients with type 1 diabetes mellitus, chronic coronary syndrome or decompensated heart failure. To get insight in the controversial relationship between cardiac autonomic dysfunction and inflammation in patients with ACS both with and without obstructive CAD and assess the precise mechanisms and molecular pathways by which these two pathophysiological conditions mutually influence each other, to characterize their prognostic implications and identify possible targets for novel therapeutic strategies.


Clinical Trial Description

A comprehensive assessment of cardiac autonomic function and inflammatory profile will be performed in ACS patients with obstructive CAD (n=45) or with NO-CAD (n=45) at coronary angiography. In the sub-acute phase (1 to 6 months after the ACS) all patients will undergo a global echocardiographic evaluation, a 24-hour ECG Holter recording to assess HRV and blood samples collection for neurotransmitter measurements, platelet activation and reactivity evaluation and inflammatory profile assessment by proteomics analysis, inflammasome activity evaluation, NLRP3, pro-IL-18 and pro-IL-1β expression level by qPCR and epigenetic analysis. A follow-up to establish clinical conditions of patients will be done after 12 months by direct clinical visit, trans-thoracic echocardiogram to evaluate cardiac remodeling, HRV assessment by 24-hour ECG Holter recording and blood sample collection to evaluate the inflammatory profile as it was assessed at baseline. ;
