RESUMO
BACKGROUND: Familial hypercholesterolaemia (FH) is a common genetic disorder causing premature cardiovascular disease (CVD). The estimated prevalence of probable or definite FH is 1:200-250 individuals, according to the Dutch Lipid Clinic Network (DLCN) criteria for FH. In Denmark approximately 12% of cases are identified. AIM: To provide knowledge of the prevalence and management of FH in general practice. DESIGN & SETTING: A collaboration between six general practice clinics and the department of cardiology at Bispebjerg hospital in Denmark. METHOD: A total of 9652 patient records were screened for hypercholesterolaemia. All patients with a low-density lipoprotein cholesterol (LDL-C) ≥5.0 mmol/l were included in the study population and their records were investigated in order to perform a diagnostic score according to the DLCN criteria. RESULTS: It was found that 2382 individuals had a lipid measurement available, and 236 of those had an LDL-C ≥5.0 mmol/l. In total, 34 individuals were found to have probable or definite FH (DLCN score ≥5). Only three individuals had been diagnosed and treated with lipid-lowering therapy. Of 236 individuals with high LDL-C, only 25 individuals met their treatment target. By excluding patients with signs of secondary hypercholesterolaemia, a subgroup of 115 individuals with potential primary hypercholesterolaemia was established. Among those, 21 individuals were found to have probable or definite FH (1:114 individuals). CONCLUSION: The study shows that there is a massive lack of recognition of FH in general practice. Despite a measured high LDL-C, the diagnosis is rarely made and only a few patients are treated accordingly. Of the patients undergoing treatment, only a few reached their treatment target.
RESUMO
INTRODUCTION: Previous studies on the effect of heart failure clinics have shown a reduction in hospitalizations, reduced cost and improved quality of life. MATERIAL AND METHODS: We report on the establishment of a heart failure clinic and its impact on heart failure hospitalizations. Since September 1, 1999, a heart failure clinic has been operated at the Frederiksberg University Hospital. The clinic was designed with both a diagnostic and a therapeutic unit. The diagnostic unit offers open access to all patients with suspected heart failure, either through referral from general practitioners or from the medical departments of the hospital. In case of confirmed systolic heart failure, the patient is referred to the therapeutic unit. RESULTS: During the two years of operation, a total of 510 patients were registered in a newly established database (HJERTER+). Of these, 352 (69%) were found to have clinical evidence of heart failure, and 304 (86% of the heart failure patients) had left ventricular (LV) systolic dysfunction (ejection fraction < or = 0.45). Before referral, most patients with LV dysfunction had been treated with no or insufficient dose of ACE inhibitor (55%), and one third received beta-blockers (32%). During the two years of operation of the clinic, there was a 23% decline in heart failure related hospital admissions to the department of cardiology. DISCUSSION: Patients with systolic heart failure are not always optimally treated. The establishment of a heart failure clinic offering the combination of diagnosing and managing congestive heart failure appears to be effective both in terms of therapy optimization and with respect to a concomitant decline in hospitalization for heart failure.
