Furthermore, PBMCs from patients with chronic ischemic HF recruited from the Istituti Clinici Scientifici Maugeri Pavia will be also used. From the data obtained from these patients and from non-decompensated subjects, the levels of BACE1-AS and BACE1 in the blood will be measured and correlated with each other and with β-amyloid levels (βA), as well as with clinically relevant parameters.', 'detailedDescription': '1.1) Validation of transcriptomic data obtained in vitro: The transcriptome of the AC16 cardiomyocyte cell line in which the expression of BACE1-AS was induced by lentivirus vectors will be analyzed, thus identifying the transcripts specifically modulated by BACE1-AS. The data obtained in vitro will be validated by analyzing the RNAs extracted from 20 HF patients and 20 controls. These RNA samples are already available thanks to the RNA\\_HF\\_AS project "Study of the transcriptome in heart failure and aortic stenosis" (San Raffaele Hospital - Milan, Ethics Committee CE 85/int/2016).\n\n1.2) Validation of epigenetic data: The effect of BACE1-AS on the state of DNA methylation will be studied in the AC16 cardiomyocyte cell line. In over-expressing BACE1-AS cells, DNA hypomethylation will be evaluated by MS-HRM and pyrosequencing studies of bisulfite-modified genomic DNA of 69 enhancer sequences identified by us as candidates in preliminary studies. The data thus obtained will be validated in 20 cardiac biopsies from patients with post-ischemic HF and in 20 controls. Left ventricular biopsies will be taken after obtaining informed consent from 20 patients suffering from non-terminal dilated cardiomyopathy (DCM) undergoing left ventricular reconstruction (SVR) surgery at the San Donato Policlinico. A sufficient number of samples with these characteristics have already been obtained from IRCCS Policlinico San Donato as part of the RNA\\_HF\\_AS project (San Raffaele Hospital - Milan, Ethics Committee CE 85/int/2016). and not completely used for the study.\n\n1.3) Study of the expression levels of BACE1-AS, BACE1 in PBMC of patients with ischemic cardiomyopathy.\n\nThe expression levels of BACE1 and BACE1-AS will be measured in PBMCs from the following groups:\n\nGroup 1:\n\n130 ACS patients with left ventricular systolic dysfunction (left ventricular ejection fraction (LVEF) \\< 45%) at 12 months follow-up after PCI, as well as 100 control subjects, recruited from the Interventional Cardiology Unit of the IRCCS Policlinico San Donato. The measurements of BACE1, BACE1-AS and βA will be carried out at the Molecular Cardiology Laboratory of the IRCCS Policlinico San Donato. These activities are included among those approved in the RNA\\_ACS protocol (Ethics Committee of the San Raffaele Hospital - Milan 14/int/2020) "RNA as prognostic biomarkers in patients with acute coronary syndrome"\n\nGroup 2:\n\n240 patients with chronic post-ischemic HF and 120 age/sex-matched healthy controls.
