    CHRONIC HEART FAILURE;
    Scientists at Yerevan State University, Department of Physiology
    target chronic heart failure



    Fresh data on chronic heart failure are presented in the report
    "Calcium-regulating peptide hormones and blood electrolytic balance
    in chronic heart failure. Calcium-regulating system is important for
    the functional activity of myocardium. However, little is known about
    the role of this system in the pathogenesis of cardiovascular
    diseases," researchers in Yerevan, Armenia report.

    "Blood samples from the patients with chronic heart failure (CHF)
    caused by ischaemic disease (coronary artery disease) (NYHA class
    I-IV) were used to analyze the levels of calcium, inorganic
    phosphate, sodium, potassium, parathyroid hormone (PTH) and
    parathyroid hormone-related protein (PTHrP). The heart beat rate and
    arterial blood pressure were chosen as additional tests for the
    functional status of cardiovascular system. The alteration of
    electrolytes homeostasis was found dependent on the severity of the
    pathology being maximally expressed in the NYHA class IV patients.
    Similar tendency was demonstrated for circulating PTH and PTHrP with
    the highest blood concentrations observed in patients of the NYHA
    class III and IV. The extent of these changes was found more
    pronounced in the female patients," wrote K.P. Arakelyan and
    colleagues, Yerevan State University, Department of Physiology.

    The researchers concluded: "It is suggested that the
    calcium-regulating hormonal system is involved in the pathogenesis of
    the ischaemic heart disease; however the sharp increase of PTH and
    PTHrP at the severe stages of pathology may play a compensatory role
    in maintaining the heart function."

    Arakelyan and colleagues published their study in Regulatory Peptides
    (Calcium-regulating peptide hormones and blood electrolytic balance
    in chronic heart failure. Regulatory Peptides, 2007;142(3):95-100).

    Medical University, Dept. of Physiology, 375025 Yerevan, Armenia.

    Publisher contact information for the journal Regulatory Peptides is:
    Elsevier Science BV, PO Box 211, 1000 AE Amsterdam, Netherlands.
