Prevalence and management of familial hypercholesterolaemia in patients with chest pain admitted to hospital: a retrospective observational study.
Observational study in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesPatients with familial hypercholesterolaemia (FH) are genetically burdened by a lifelong elevation of the low-density lipoprotein cholesterol (LDL-C) level, putting them at a very high risk of premature ischaemic heart disease (IHD). This study aims to assess the prevalence of FH among patients admitted for IHD and the preventive treatment status before admission.
designObservational, retrospective, register-based study.
settingIndividuals discharged with a diagnosis of IHD were enrolled consecutively throughout 2012-2016 from the cardiac care units of two hospitals in Copenhagen.
participants4223 individuals were discharged during the period. Inclusion criteria for further investigation were the availability of one measurement of LDL-C at the time of admission. In total, 2797 individuals were included for further investigation. There were no exclusion criteria. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary objective has been to determine the prevalence of FH in the population. The secondary objective has been to determine the use of lipid-lowering therapy and to which extend the individuals reach their treatment goal.
resultsAmong the 2797 consecutive patients evaluated, the prevalence of potential FH was 7.7% (1: 13) and 6.8% (1:15) had probably or definite FH. The prevalence of FH was age-dependent: Among the 680 patients (24.3%) with premature IHD (men <55 years/women <60 years), 136 patients (20.0%) had potential FH and 21 (3.1%) had probable/definite FH. None were diagnosed and almost none attained their treatment goal.
conclusionsThere is still a massive lack of recognition of FH in patients admitted to a cardiac care unit with a diagnosis of IHD. Despite a measured high LDL-C, the diagnosis was not made for any patients not even in patients who were admitted at an early age or had a previous cardiovascular event.
