Zusammenfassung

Die LDL-Cholesterin (LDL-C)-Senkung mit Statinen reduziert das Risiko für kardiovaskuläre Erkrankungen, jedoch erreichen nicht alle Patienten den angestrebten LDL-C-Zielwert und es verbleibt ein residuales Risiko. LDL-Partikel werden aus dem Plasma hauptsächlich durch LDL-Rezeptoren (LDL-R) in Hepatozyten aufgenommen. Die LDL-R werden zurück zur Plasmamembran transportiert und stehen erneut zur LDL-C-Bindung zur Verfügung. Dieses „Recycling“ der LDL-R wird durch die Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) reguliert. PCSK9 bindet an die LDL-R und führt zu deren Abbau. Eine Hemmung von PCSK9 resultiert in einer verstärkten Expression hepatischer LDL-R und führt zu einer Reduktion des LDL-C im Plasma. Daher stellt eine therapeutische Inhibition von PCSK9 (z.B. durch monoklonale Antikörper) eine potente Intervention für eine LDL-C-Senkung dar, deren klinische Bedeutung aktuell in großen klinischen Studienprogrammen geprüft wird.

Bei Herzinsuffizienz muss „Eisenmangel“ neu definiert werden!

16.05.2024 Herzinsuffizienz Nachrichten

Bei chronischer Herzinsuffizienz macht es einem internationalen Expertenteam zufolge wenig Sinn, die Diagnose „Eisenmangel“ am Serumferritin festzumachen. Das Team schlägt vor, sich lieber an die Transferrinsättigung zu halten.

Herzinfarkt mit 85 – trotzdem noch intensive Lipidsenkung?

Profitieren nach einem akuten Myokardinfarkt auch Betroffene über 80 Jahre noch von einer intensiven Lipidsenkung zur Sekundärprävention? Um diese Frage zu beantworten, wurden jetzt Registerdaten aus Frankreich ausgewertet.

Erwachsene, die Medikamente gegen das Aufmerksamkeitsdefizit-Hyperaktivitätssyndrom einnehmen, laufen offenbar erhöhte Gefahr, an Herzschwäche zu erkranken oder einen Schlaganfall zu erleiden. Es scheint eine Dosis-Wirkungs-Beziehung zu bestehen.

Apolipoprotein B (ApoB) ist ein genauer Risikomarker für atherosklerotisch bedingte Erkrankungen. Aber das LDL-Cholesterin doch auch – lohnt sich also die ApoB-Messung überhaupt?
