Lipid metabolism disorders play a key role in determining cardiovascular risk. The level of low-density lipoprotein cholesterol is a significant factor in the pathophysiology of atherosclerosis and an indicator, the assessment of which reduces the risk of cardiovascular events. The prevalence of acute coronary syndrome in Russia remains at a high level. To date, the successful implementation and implementation of standards for the management of acute coronary syndrome has significantly reduced hospital mortality rates, however, secondary prevention issues remain relevant. Despite a wide range of lipid-lowering drugs, the use of which at maximum doses in acute coronary syndrome does not allow reaching the target levels of the lipid spectrum, the risk of developing repeated cardiovascular events remains high. Recently, a promising direction is the use of type 9 subtilisin/ kexin proprotein convertase inhibitors for the intensification of lipid-lowering therapy in patients with acute coronary syndrome. This article presents the clinical case of the successful use of one of the inhibitors of the proprotein convertase of subtilisin/kexin type 9, alirocoumab, in lowering low-density lipoprotein cholesterol and thereby reducing the risk of repeated cardiovascular events in a patient with acute coronary syndrome.

Abstract Introduction Dyslipidemia, especially an increase in the low-density lipoprotein cholesterol (LDL-C) has been established as one of the most important risk factors for atherosclerotic cardiovascular diseases. In contrast, some recent studies have shown that the low LDL-C level was associated with short-term poor prognosis in patients with cardiovascular disease, and this is so-called “cholesterol paradox”. However, there is few data evaluating the effects on long-term outcome of “cholesterol paradox” in patients with acute coronary syndrome (ACS). Purpose The purpose of this study was to examine whether the low LDL-C level on admission affect long-term prognosis in patients with ACS. Methods A total of 434 ACS patients who survived to hospital discharge were enrolled in this study. All patients were statin-naïve on admission, and were received statin therapy after hospitalization. Patients were divided into the low LDL-C (≤114 mg/dl) and high LDL-C (&gt;114 mg/dl) groups using the first tertile of the LDL-C level on admission. The primary endpoint was composite outcomes of all-cause death, myocardial infarction, ischemic stroke, hospitalization for congestive heart failure and unplanned revascularization. Results During a median follow-up period of 5.5 years, primary endpoint occurred in 117 patients. Overall, event-free rates differed significantly between the low and high LDL-C groups, demonstrating the lower event-free rate in patients with the low LDL-C group (38.9% in low LDL-C group versus 20.7% in high LDL-C group, p=0.0002; Figure). Even after adjustment for age, sex, body mass index, and various classical risk factors, the low LDL-C group was significantly at higher risk for primary composite outcomes compared to the high LDL-C group (adjusted hazard ratio 1.65, 95%-confidence interval 1.10–2.49, p=0.02). Conclusion In patients with ACS, the low LDL-C level on admission was significantly associated with long-term worse prognosis, regardless of statin therapy at discharge. In ACS patients with low LDL-C level, it might be necessary for elucidating the residual risk for secondary adverse event to improve their prognosis.

Aims Statins are pivotal to the secondary prevention of major adverse cardiovascular events, but some patients are statin-intolerant. We examined the effects of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab on the risk of major adverse cardiovascular events according to the intensity of background statin treatment. Methods and results The ODYSSEY OUTCOMES trial compared alirocumab with placebo in 18,924 patients with acute coronary syndrome and dyslipidaemia despite intensive or maximum-tolerated statin treatment (including no statin if intolerance was documented). The primary outcome (major adverse cardiovascular events) comprised coronary heart disease death, non-fatal myocardial infarction, ischaemic stroke, or unstable angina. Median follow-up was 2.8 years. Baseline statin treatment was high-intensity (88.8%), low/moderate-intensity (8.7%) or none (2.4%). Median baseline low-density lipoprotein cholesterol was 86, 89 and 139 mg/dL ( P < 0.001) in these statin treatment categories, respectively. Alirocumab produced similar relative reductions in low-density lipoprotein cholesterol from baseline across statin treatment subgroups, but the mean absolute reductions differed (52.9, 56.7 and 86.1 mg/dL, respectively; P < 0.001). With placebo, the incidence of major adverse cardiovascular events was highest in the no statin subgroup (10.8%, 10.7% and 26.0% respectively). Alirocumab reduced major adverse cardiovascular events in each statin subgroup (hazard ratio 0.88, 95% confidence interval (CI) 0.80–0.96; 0.68, 0.49–0.94; and 0.65, 0.44–0.97, respectively; Pinteraction = 0.14) with a gradient of absolute risk reduction: 1.25%, 95% CI 0.34–2.16; 3.16%, 0.38–5.94; 7.97%, 0.42–15.51; Pinteraction = 0.106). Conclusions PCSK9 inhibition with alirocumab reduces the relative risk of major adverse cardiovascular events after acute coronary syndrome irrespective of background statin treatment. However, patients on no statin are at high absolute risk for recurrent major adverse cardiovascular events; alirocumab substantially reduces that risk. PCSK9 inhibition may be an important therapeutic strategy for statin-intolerant patients with acute coronary syndrome.

The aim of this review was to present the recently published results of ODYSSEY OUTCOMES trial and discuss the clinical perspective of these data. Patients with acute coronary syndrome are at very high risk of recurrent ischemic cardiovascular complications, especially during the first year after the event. The use of high-intensity statin therapy in this group of patients does not always lead to the achievement of target levels of atherogenic lipoproteins. PCSK9 inhibitors, administered in addition to statins, can provide additional reduction of low-density lipoprotein cholesterol, which leads to further improvements of outcomes in patients with atherosclerotic cardiovascular disease. According to the latest results from ODYSSEY OUTCOMES trial, among patients with recent acute coronary syndrome, who were receiving high-intensity statin therapy, the risk of recurrent ischemic cardiovascular events was lower among those who were treated with alirocumab then among those who received placebo. The treatment with alirocumab in patients with recent acute coronary syndrome was associated with reduction in death from any causes. The absolute risk reduction with alirocumab was the most prominent in the subpopulation of patients with low-density lipoprotein cholesterol ≥2,6 mmol/l at baseline. These results have implication for clinical practice and may play an important role for the improvement of outcomes in patients at highest cardiovascular risk after acute cardiovascular syndrome.
