Overactivation of renin-angiotensin system (RAS) is one of the main pathophysiological features in the evolution of chronic heart failure (CHF). The (pro)renin receptor ((P)RR) represents an important player in a tissue renin-angiotensin system (tissue RAS), which mediates tissue injury through fibrosis and hypertrophy of the affected organs in CHF patients. In our study we used plasma samples from 556 elderly subjects with CHF and 198 healthy participants in order to evaluate prognostic and diagnostic potential of s(P)RR in setting of CHF. The patients with CHF showed significantly higher plasma levels of s(P)RR than the healthy volunteers (p=0.0005). We observed association between higher s(P)RR plasma concentrations and lower left ventricular ejection fraction and higher degree of left ventricular dilatation on baseline echocardiography examination of the CHF patients. Elderly CHF patients with higher baseline s(P)RR plasma concentration were at same risk for death, stroke and hospitalization due to heart failure worsening at mean follow-up from forty-eight months in comparison to low s(P)RR counterparts.

D011956	Receptors, Cell Surface	Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D012084	Renin-Angiotensin System	A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D006333	Heart Failure	A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
