ABSTRACT
OBJECTIVES:
To evaluate the importance of various variables reflecting neuroendocrine activation in relation to prognosis in patients with congestive heart failure (CHF).DESIGN:
Plasma levels of noradrenaline, adrenaline, neuropeptide Y, substance P, calcitonin gene-related peptide, vasopressin and atrial natriuretic peptide were measured in patients presenting with CHF and related to survival time. Survival time was calculated from the time-point of this investigation until the month when the patient died or until December 1992. The follow-up period ranged up to 60 months. Seven of the 31 patients were still alive at the end of this period.SETTING:
Lund University Hospital, Sweden.SUBJECTS:
Thirty-one patients with CHF due to ischaemic heart disease. Six patients had a degree of heart failure corresponding to NYHA I-II and 25 corresponding to NYHA III-IV. Ten of these 25 patients were on angiotensin converting enzyme (ACE) inhibition in addition to therapy with digoxin and diuretics. The catecholamine and neuropeptide levels were compared to those of a control group of 31 healthy subjects aged 20-80 years. INTERVENTION There were not any specific intervention in addition to the treatment for heart failure as outlined above. MAIN OUTCOMEMEASURES:
Survival time until death from heart disease or until the end of the follow up period in December 1992.RESULTS:
There were inverse relationships between survival time on one hand and plasma values of noradrenaline (r = -0.49; P < 0.01) and atrial natriuretic peptide (r = -0.49; P < 0.01) on the other hand. There was a significant correlation between the plasma values of noradrenaline and atrial natriuretic peptide (r = 0.50; P < 0.01).CONCLUSION:
Increased plasma levels of noradrenaline and atrial natriuretic peptide are of major importance as prognostic markers in patients with CHF.
