LDL-C-Senkung 2026: Zielwerte, Therapiealgorithmen und neue Substanzen // LDL-C lowering therapy 2026 – targets, therapy algorithm, new drugs Journal für Kardiologie - Austrian Journal of Cardiology 2026; 33 (5-6): 95-101 Volltext (PDF) Summary Abbildungen Keywords: Atherosklerose, Bempedoinsäure, Ezetimib, Koronare Herzkrankheit, LDL-C, lipidsenkende Medikation, PCSK9-Hemmer, Statine, atherosclerotic cardiovascular disease, bembedoic acid, ezetimibe, lipid-lowering agents, PCSK9 inhibitor, statins LDL cholesterol (LDL-C) is causally implicated in the development and progression of atherosclerotic cardiovascular disease (ASCVD). Accumulation and oxidation of LDL-C within the arterial wall triggers inflammatory processes that promote plaque formation and destabilization. Both the magnitude and duration of LDL-C exposure determine lifetime cardiovascular risk, as do the extent and timing of pharmacological LDL-C lowering. A reduction of as little as 1 mmol/L (approximately 40 mg/dL) significantly reduces the risk of cardiovascular events; recent trial data provide compelling evidence for the concept of “the lower the better”, irrespective of the lipid-lowering agent used. The 2025 ESC/EAS guideline update recommends risk stratification based on modifiable and non-modifiable risk factors – with high-sensitivity CRP and lipoprotein(a) explicitly included for the first time – alongside established tools such as SCORE2 for individuals without known cardiovascular disease. The updated guidelines also place greater emphasis on lifetime cardiovascular risk, which is particularly relevant for identifying high-risk constellations requiring treatment in younger individuals. Recommended LDL-C targets in patients with established atherosclerotic cardiovascular disease (ASCVD) are < 55 mg/dL and < 40 mg/dL, respectively, goals that can generally only be achieved through combination therapy. Beyond statins as the cornerstone of treatment, a range of effective add-on therapies is now available – including ezetimibe, bempedoic acid, PCSK9 inhibitors, and siRNA-based therapies – enabling target attainment in the majority of patients. Innovative approaches, including oral PCSK9 inhibitors and gene therapy strategies, hold promise for even more effective and individualized LDL-C lowering in the future.
Kurzfassung: LDL-Cholesterin (LDL-C) ist kausal für
die Entstehung und Progression atherosklerotischer
Gefäßerkrankungen verantwortlich. Die Akkumulation
und Oxidation von LDL-C in der Gefäßwand
löst entzündliche Prozesse aus, die Plaquebildung
und -destabilisierung fördern. Höhe und Dauer der
LDL-C-Exposition bestimmen das kardiovaskuläre
Lebenszeit-Risiko, ebenso wie das Ausmaß und der
Beginn einer pharmakologischen LDL-C-Senkung.
Bereits eine Reduktion um 1 mmol/L (rund 40 mg/
dL) senkt signifikant das Risiko für kardiovaskuläre
Ereignisse; rezente Studienergebnisse belegen klar
das Konzept „the lower, the better“, unabhängig vom
eingesetzten LDL-C-senkenden Wirkstoff. |
