    Abstract:
    BACKGROUND: The cross-sectional observational International ChoLesterol management Practice Study study assessed achievement of European Society of Cardiology/European Atherosclerosis Society low-density lipoprotein cholesterol (LDL-C) targets in patients outside Western Europe. OBJECTIVE: The aim of the study was to assess LDL-C goal achievement in International ChoLesterol management Practice Study participants with familial hypercholesterolemia (FH). METHODS: A total of 334 patients (aged ≥18 years) with definite or probable FH (Dutch Lipid Clinic Network score ≥6; 43.1% genetically confirmed) who had been receiving stable lipid-modifying therapy (LMT) for ≥3 months were enrolled. RESULTS: The mean ± standard deviation age of the patients was 58.5 ± 13.1 years, 49.1% were male, and 48.2% had coronary artery disease. Most were receiving statin (∼99%). Of these, 57.6% were on high-intensity statin therapy, 49.1% on the highest dose available, and 13.0% used a statin together with a cholesterol absorption inhibitor (CAI). Mean ± standard deviation LDL-C level was 5.6 ± 3.0 mmol/L before LMT and 3.3 ± 2.0 mmol/L at enrollment. Overall, 32.0% of patients achieved their LDL-C target. Target achievement rates were 36.6% for patients with coronary artery disease, and 27.5% for those without, and 27.9%, 28.0%, and 37.5% for patients treated with a statin plus CAI, highest-dose statin (no CAI), and lower-dose statin (no CAI), respectively. CONCLUSIONS: LDL-C target achievement rates were low in patients with FH, even in those receiving intensive LMT. Factors that are likely to have contributed to the low LDL-C target achievement rates include high baseline LDL-C, inadequate statin dosages, and low use of CAI. Many patients would have been eligible for proprotein convertase subtilisin/kexin type 9 inhibitor therapy.
