Die Highlights vom Kongress des American College of Cardiology 2024

Im April diskutierten die Herz-Kreislauf-Spezialisten aus der ganzen Welt auf dem  Kongress des American College of Cardiology (ACC) u.a. neue Therapieansätze bei akutem Myokardinfarkt, koronarer Herzerkrankung, kardiogenem Schock oder Aortenklappenstenose. In unserem Kongress-Dossier haben wir für Sie Berichte über die „Late-Breaking Trials“ und andere wichtige Studien zusammengestellt.

Abstract

Throughout life, damage to the vascular endothelium is pivotal in the development of cardiovascular disease. Therefore, a detailed understanding of the underlying mechanisms involved in endothelial cell restoration is of fundamental importance for preventive and therapeutic concepts in cardiovascular disease. The goal of regenerative medicine is the use of tissue-specific progenitor cells for a more effective repair process with reduction of fibrocellular remodelling, fibrosis and loss of functional properties.
According to the hitherto assumed primary model of endothelial regeneration only adjacent and intact mature endothelial cells replace damaged endothelium. Since Asahara and colleagues first described that a peripheral blood mononuclear cell population was able to differentiate into endothelial cells in vitro and incorporate into ischemic tissue at sites of angiogenesis in vivo, the model of endothelial regeneration has been extended. The majority of clinical trials on human cell therapy for ischemic vascular disease are based on cell surface antigen expression of CD34 or VEGFR2 to identify endothelial progenitor cells.
A precise characterization of the angiogenic properties of different subsets of endothelial regenerating cells and their course of action to gain sufficient long-term regeneration of the injured vessel is a necessary precondition before clinical trials of human cell therapy become a routine reality.

„Übersichtlicher Wegweiser“: Lauterbachs umstrittener Klinik-Atlas ist online

17.05.2024 Klinik aktuell Nachrichten

Sie sei „ethisch geboten“, meint Gesundheitsminister Karl Lauterbach: mehr Transparenz über die Qualität von Klinikbehandlungen. Um sie abzubilden, lässt er gegen den Widerstand vieler Länder einen virtuellen Klinik-Atlas freischalten.
