Despite elevated low-density lipoprotein (LDL) cholesterol levels, some older subjects with heterozygous familial hypercholesterolemia (HeFH) do not develop atherosclerotic cardiovascular disease (ACVD) during their lifetime. The factors related to this resilient state have not been fully established. The aim of this study was to evaluate differential characteristics between older HeFH subjects with and without ACVD and factors associated with the presence of ACVD. Subjects were part of the Spanish Atherosclerosis Society Dyslipidemia Registry, and those ≥ 70 years old and with HeFH were included. Baseline characteristics of these subjects with and without ACVD were compared. A multivariate analysis was performed to assess factors associated with the presence of ACVD. A total of 2148 subjects with HeFH were included. Resilient subjects were mostly female, younger and presented fewer comorbidities with respect to the ACVD group. Subjects without ACVD had higher baseline high-density lipoprotein (HDL) cholesterol (55.8 ± 17.1 vs. 47.9 ± 15.4 mg/dL; p < 0.001) and lower lipoprotein(a) [Lp(a)] (53.4 ± 67.9 vs. 66.6 ± 85.6 mg/dL; p < 0.001) levels with respect to those in the ACVD group. Lp(a) and the presence of ≥3 risk factors were associated with the presence of ACVD.

Background: Given the increasing prevalence of dyslipidaemia and multimorbidity in the elderly population, the lack of safety data on combined statin–fenofibrate therapy in this age group represents a critical gap. The post hoc subgroup analysis of the Pose study addresses this issue. Materials and methods: The POSE study was a 3-year, real-world, observational, comparative, non-interventional study conducted in Europe. Patients with mixed dyslipidaemia treated either by a fixed-dose combination of pravastatin 40 mg/fenofibrate 160 mg or a moderate-intensity statin monotherapy were enrolled. Safety outcomes included the occurrence of renal or urinary disorders, musculoskeletal or connective tissue disorders, hepatobiliary disorders, cholelithiasis, thromboembolic events, pancreatitis, worsening diabetes mellitus, elevated blood homocysteine levels, interstitial pneumopathy, phototoxicity, and fatal or non-fatal cardiovascular events. Laboratory parameters related to lipid control and renal, muscular, and hepatic functions were additionally evaluated. The post hoc analysis focuses on the subgroup of patients aged 75 years and older. Results: A total of 458 patients were included in the analysis. The majority had hypertension (79.3%) and diabetes mellitus (55.0%). Over the 3-year study period, there was no difference in incidence rate of safety events between groups (RR = 2.18 [95% CI = 0.99–4.81]). Renal and urinary disorders were more frequent with the combination (5.5% vs 0.8%), whereas musculoskeletal disorders, aggravated diabetes mellitus, and cardiovascular events, showed no significant difference between groups, the 95% CI spanning 1. Globally, there were no significant differences regarding the evolution of hepatic, muscle and renal biological parameters. As expected, the pravastatin/fenofibrate combination achieved a more pronounced TG reduction and a modest increase in HDL-C, whereas the statin group showed more modest changes in these parameters. Conclusions: This real-life observational post hoc subgroup analysis suggests that in patients aged 75 years and older with mixed dyslipidaemia at high or very high CV risk, pravastatin 40 mg/fenofibrate 160 mg is well tolerated and can be used with acceptable long‑term safety. The combination offers additional TG lowering and HDL‑C improvement beyond moderate‑intensity statin monotherapy, without a significant increase in overall safety events over three years. The study confirms the positive benefit / risk balance of the fixed-dose combination of pravastatin 40 mg/fenofibrate 160 mg in this growing population of patients aged 75 years and older.

Results: A total of 458 patients were included in the analysis. The majority had hypertension (79.3%) and diabetes mellitus (55.0%). Over the 3-year study period, the incidence rate of composite safety events was numerically higher with the combination, though this did not reach statistical significance (RR = 2.18 [95% CI = 0.99–4.81]). Renal and urinary disorders were more frequent with the combination (5.5% vs. 0.8%), whereas musculoskeletal disorders, aggravated diabetes mellitus, and cardiovascular events showed no significant difference between groups, as the 95% confidence interval included 1. Globally, there were no significant differences regarding evolution of the hepatic, muscle, and renal biological parameters. From baseline to Year 3, TG levels decreased by 44.3% with pravastatin/fenofibrate and by 10.7% with statin monotherapy, while HDL-C levels increased by 26.5% and 0.4%, respectively. Conclusions: This real-life observational post hoc subgroup analysis suggests that in patients aged 75 years and older with mixed dyslipidemia at high or very high CV risk, pravastatin 40 mg/fenofibrate 160 mg demonstrates an acceptable long-term safety profile. The combination offers additional TG lowering and HDL-C improvement beyond moderate-intensity statin monotherapy, without a significant increase in overall safety events over three years.
