    Abstract:
    OBJECTIVES: Modern diagnostics of chronic heart failure (CHF) is based on echocardiography. Angiotensin converting enzyme inhibitors (ACEIs) or angiotensin-II-antagonists (AIIAs) in case of ACEI intolerance, and beta-blockers are recommended as first-line drugs in patients with CHF and left ventricular systolic dysfunction. The aims of this study were to analyse the diagnostics and treatment of patients with CHF and to identify the optimal drug profile (target level) with regard to ACEI/AIIA- and beta-blocker treatment. METHODS: The medical records of all patients (n=635) from a part of a Swedish county who had a diagnosis of CHF in the year 2000 were analysed retrospectively. RESULTS: The prevalence of CHF increased with age, from 0.9% and 1.6% in the age group 60-64 years in women and men, respectively, to 8.8% and 11.5%, respectively, in the age group 80-84 years. Only 17.6% of the patients had been examined by means of echocardiography. Of the patients without any contra-indication for the drugs, 45.9% received treatment with ACEI/AIIAs and 41.8% with beta-blockers. Treatment with ACEI/AIIAs and beta-blockers was given to 21.3%. The corresponding proportions for treatment of patients with CHF verified by echocardiography were 88.0% (ACEI/AIIA), 52.0% (beta-blocker) and 46.7% (the combination). The target level of the combination treatment was estimated to be about 70% in a group of unselected patients with CHF. CONCLUSIONS: CHF was not optimally diagnosed in this cohort of patients. Correct diagnosing seems to be associated with more adequate treatment.
