Molecular Pathways of Cardiac Remodellation in Patients With Acute and Chronic Left Ventricular Disfunction — HFrEF  

Heart Failure Clinical Trial

Official title: Molecular Pathways of Cardiac Remodellation in Patients With Acute and Chronic Left Ventricular Disfunction (HFrEF)

Status Active, not recruiting

Clinical Trial Summary

Chronic heart failure represents an extremely complex clinical syndrome, defined as the inability of the heart muscle to generate a volume adequate to the metabolic needs of peripheral tissues, or to do so only in the face of high filling pressures intracavity. Heart failure is one of the leading causes of mortality and morbidity in Western countries.

Despite advances in the therapeutic field, the prognosis of patients with heart failure of ischemic and non-ischaemic aetiology still remains unfavorable, with a mortality rate of 50% 5 years after the first hospitalization.Therefore, a deeper understanding of the pathophysiological mechanisms involved in heart failure and adverse ventricular remodeling is essential.

Clinical Trial Description

The study will be interventional, prospective, and single-center. Partecipants will be divided into three groups:

1. 30 partecipants admitted to our hospital with the diagnosis of STEMI-type ACS and ejection fraction ≤ 35% on echocardiographic evaluation

2. 30 partecipants with non-ischaemic dilated cardiomyopathy and ejection fraction ≤35% on echocardiographic evaluation

3. 15 partecipants diagnosed with STEMI-type ACS and ejection fraction > 50% on echocardiographic evaluation

4. 15 controls with normal left ventricular contractile function. The study foresees a phase of patient recruitment, in which, in the hours immediately following the blood sampling, the isolation of the PBMCs, their incubation and cytofluorimetric analysis will be carried out and the conservation of the material to be analyzed subsequently by molecular biology and immunochemistry. ;
