Causes of failure to achieve the low density lipoprotein cholesterol therapeutic target in patients with high and very high vascular risk controlled in Lipid and Vascular Risk Units. EROMOT study.

Objectives: Determination of the level of achievement of the low density lipoprotein cholesterol (LDL-C) therapeutic target in patients with high and very high vascular risk treated in Lipid Units, as well as the causes of non-achievement.

Patients And Method: Multicentre retrospective observational study that included patients over 18 years with high and very high vascular risk, according to the criteria of the 2012 European Guidelines on Cardiovascular Disease Prevention, referred consecutively to Lipid Units between January and June 2012 and with follow-up two years after the first visit.

Results: The study included a total of 243 patients from 16 lipid units. The mean age was 52.2 years (SD 13.7), of whom 62.6% were males, and 40.3% of them were very high risk. At the first visit, 86.8% (25.1% in combination) and 95.0% (47.3% in combination) in the second visit (P<.001) were treated with lipid-lowering treatment. The therapeutic target was achieved by 28% (95 CI: 22.4-34.1). As regards the causes of non-achievement, 24.6% were related to the medication (10.3% maximum tolerated dose and 10.9% due to the appearance of adverse effects), 43.4% due to the physician (19.4% by inertia, 13.7% considering that target already reached), and 46.9% due to the patient, highlighting the therapeutic non-compliance (31,4%).

Conclusions: LDL-C targets were achieved in about one-third of patients. The low adherence of the patient, followed by medical inertia are the most frequent causes that can explain these results.
