- Brief Summary
The congestive heart failure (HF) is a condition associated with substantial morbidity, mortality, and high healthcare expenditures. From the pathophysiological standpoint, several mechanisms contribute to the progression and dysfunction of the failing heart such as an increased hemodynamic overload, impaired myocyte calcium cycling, upregulated apoptotic activity, deficient or increased production of extracellular matrix, genetic predilections and, finally, excessive neurohumoral stimulation. The vasoactive neurohumoral systems such as sympathetic nervous system, renin-angiotensin-aldosterone system (RAAS) and arginine vasopressin (AVP) system all play a role in maintaining volume and circulatory homeostasis in the situation of impaired cardiac output.
Catestatin (CST), on another hand, is a novel endogenous peptide cleaved from chromogranin A (CgA) that is involved in the regulation of cardiac function and arterial blood pressure. The role of this peptide is to elicit potent catecholamine release-inhibitory activity by acting at the level of the nicotinic acetylcholine receptors. Therefore, the main hypothesis of this study is that the observed serum CST levels will reflect the degree of neurohormonal activation in HF, showing a significant relationship with the degree of disease severity as measured by relevant functional classifications (such as NYHA class and/or similar). Secondly, investigators expect to detect correlation of catestatin serum levels with the established risk stratification scores in HF and with the echocardiographic parameters of the ventricular function, both in terms of systolic and diastolic cardiac function. Parameters of inflammation, NT-proBNP, hs-cTnI, renal function parameters, and basic hematologic/biochemistry indices from peripheral blood will also be obtained and analyzed for all study participants.
Furthermore, according to the latest European Society of Cardiology (ESC) guidelines for the diagnosis and treatment of acute and chronic HF, participants with established congestive HF and the whole spectrum of left ventricular ejection fractions ranging from \<40% to ≥50% will be included in the study.
Finally, all echocardiographic and laboratory parameters obtained from peripheral blood will be recorded and compared with respective healthy and matched control participants while participants diagnosed with HF will additionally be analyzed for potential differences between subgroups of interest.

Group Intervention Description Congestive Heart Failure (NYHA II-IV) Blood withdrawal for laboratory analysis N=90 Patients with a clinically documented diagnosis of congestive heart failure (CHF), as assessed per New York Heart Association (NYHA) functional classification will be prospectively and consecutively enrolled in this group. Patients will be of both sexes, enrolled in 1:1 ratio. All subjects in this group will undergo blood withdrawal for laboratory analysis, transthoracic echocardiography (TTE) examination and will be treated with the Standard-of-care treatment according to their current clinical condition at admission. Congestive Heart Failure (NYHA II-IV) Transthoracic echocardiography (TTE) N=90 Patients with a clinically documented diagnosis of congestive heart failure (CHF), as assessed per New York Heart Association (NYHA) functional classification will be prospectively and consecutively enrolled in this group. Patients will be of both sexes, enrolled in 1:1 ratio. All subjects in this group will undergo blood withdrawal for laboratory analysis, transthoracic echocardiography (TTE) examination and will be treated with the Standard-of-care treatment according to their current clinical condition at admission. Healthy Control Group Transthoracic echocardiography (TTE) N=30 Healthy volunteers (both sexes, enrolled in 1:1 ratio) with a negative history of cardiovascular diseases will be enrolled in this group that will serve as a study control. All subjects in this group will undergo blood withdrawal for laboratory analysis and transthoracic echocardiography (TTE) examination. Congestive Heart Failure (NYHA II-IV) Standard-of-care treatment N=90 Patients with a clinically documented diagnosis of congestive heart failure (CHF), as assessed per New York Heart Association (NYHA) functional classification will be prospectively and consecutively enrolled in this group. Patients will be of both sexes, enrolled in 1:1 ratio. All subjects in this group will undergo blood withdrawal for laboratory analysis, transthoracic echocardiography (TTE) examination and will be treated with the Standard-of-care treatment according to their current clinical condition at admission. Healthy Control Group Blood withdrawal for laboratory analysis N=30 Healthy volunteers (both sexes, enrolled in 1:1 ratio) with a negative history of cardiovascular diseases will be enrolled in this group that will serve as a study control.

- Primary Outcome Measures
Name Time Method Catestatin levels in blood serum 3 months The goal is to determine and compare serum catestatin levels in patients with congestive heart failure, stratified by the left ventricular ejection fraction (LVEF) in three groups: reduced, mid-range, and preserved ejection fraction (HFrEF, HFmrEF, HFpEF). Furthermore, catestatin plasma levels will be compared between patients with congestive heart failure and healthy volunteers.
- Secondary Outcome Measures
Name Time Method Relationship of serum catestatin levels with the echocardiographic parameters of cardiac function 3 months The potential relationship of catestatin serum levels with established parameters of systolic and diastolic cardiac function, as assessed by transthoracic echocardiography among patients with congestive heart failure will be examined.
Relationship of serum catestatin levels with the selected laboratory indices 3 months The potential relationship of catestatin serum levels with the NT-proBNP, inflammatory biomarkers and standard hematologic/biochemical indices will be examined.
