[Dyslipidemia in high cardiovascular risk patients. Initial results from the REMEXDIS-IMSS study].

Background: There is no national registry on dyslipidemia and low-density lipoprotein cholesterol (LDL-c) goals by risk groups for atherosclerotic cardiovascular disease (ACVD) focused on beneficiaries of the Mexican Institute for Social Security (IMSS).

Objective: To determine the frequency of dyslipidemia, LDL-c goals and patients in treatment from high and very high-risk groups of ACVD.

Material and methods: Multicenter, cross-sectional, descriptive study. This article derives from the Mexican Registry of Dyslipidemias in patients at high-risk and very high-risk of atherosclerotic cardiovascular disease (REMEXDIS-IMSS Project). Patients with high-risk and very high-risk criteria for ACVD were included.

Results: From July 2022 to March 2023, 6000 patients were included (3289 patients in the high-risk group and 2771 in the very high-risk group). The frequency of dyslipidemia was observed in 49% of the cohort. The very high-risk group presented a higher percentage of dyslipidemia in 66.8%, acute myocardial infarction in 81.0% and angina pectoris in 21.9%. The use of statins was higher in this group (93.3%) and the LDL-c goal was achieved in 72.9% (p < 0.0001).

Conclusions: The frequency of dyslipidemia is found in almost half of the population. The very high-risk group had a higher frequency of dyslipidemia, better use of statins for indication of secondary prevention, and a greater number of patients with LDL-c goals compared to the high-risk group.
