Molecular Pathways Involved in Cardiac Remodeling in Patients With Chronic Heart Failure With Preserved Ejection Fraction by New Omics Technologies

The study, placing itself within the framework of Translational Research, aims to gain a greater understanding of the different phenotypes of patients with HFpEF, to expand knowledge of the specific immune profile, and to identify new therapeutic targets for a heterogeneous clinical syndrome, to date lacking effective medical therapy. It is also proposed to find potential biomarkers with which to distinguish early between the two subclasses of decompensation and protein alterations related to the possible development of pulmonary hypertension in patients with HFpEF and HFrEF (PH-HFpEF and PH- HFrEF, respectively). Patients who will take part in the study, following enrollment carried out on an inpatient or outpatient basis (being inpatients and control group subjects, respectively), will have follow-up visits at two times (at 1 month and at 6 months), in conjunction with regularly scheduled medical checkups, according to Good Clinical Practice.
