Abstract
Introduction: Insufficient statin/ezetimibe effectiveness for low-density lipoprotein cholesterol (LDL-C) reduction is not uncommon. A novel gene-silencing medication inclisiran has been introduced. Near-infrared spectroscopy (NIRS) allows to assess the dynamics of plaque lipid content in the context of optimal lipid-lowering pharmacotherapy. The aim of this study was to evaluate the impact of optimal hypolipidaemic pharmacotherapy, including add-on inclisiran, on the plasma lipid profile and plaque lipid content.
Methods: This study enrolled patients with stable coronary artery disease, admitted for elective percutaneous coronary intervention (PCI). NIRS of the segment of interest was performed during index PCI and 15 months later. Patients having LDL-C >1.8 mmol/L after 4-6 weeks of maximum tolerated statin/ezetimibe therapy received add-on inclisiran. Lipid profile changes within 15 months were also evaluated.
Results: Among 42 included patients, 24 drug-resistant hypercholesterolaemia participants were assigned to inclisiran therapy. After 15 months, a significant LDL-C decrease of 26.42% was established (p = 0.006), with 12 participants reaching the LDL-C goal of <1.8 mmol/L. Average 15-month LDL-C reduction was 36.03%. NIRS data demonstrated a significant reduction in maximum lipid-core burden index within 4 mm (maxLCBI4 mm) in the inclisiran group (-117.64, p = 0.004) and statin/ezetimibe group (-141.88, p = 0.004), with no significant difference between the groups (p = 0.213).
Conclusion: Results demonstrate an association between better LDL-C control and coronary plaque lipid burden reduction. Addition of inclisiran leads to remarkable LDL-C reduction in patients who have run out of statin and ezetimibe treatment options.
期刊介绍：
''Cardiology'' features first reports on original clinical, preclinical and fundamental research as well as ''Novel Insights from Clinical Experience'' and topical comprehensive reviews in selected areas of cardiovascular disease. ''Editorial Comments'' provide a critical but positive evaluation of a recent article. Papers not only describe but offer critical appraisals of new developments in non-invasive and invasive diagnostic methods and in pharmacologic, nutritional and mechanical/surgical therapies. Readers are thus kept informed of current strategies in the prevention, recognition and treatment of heart disease. Special sections in a variety of subspecialty areas reinforce the journal''s value as a complete record of recent progress for all cardiologists, internists, cardiac surgeons, clinical physiologists, pharmacologists and professionals in other areas of medicine interested in current activity in cardiovascular diseases.
