Abstract
English
Chronic heart disease is associated with abberant CpG promoter methylation, mechanistically involved cardiac fibrogenesis. Aberant CpG promoter methylation is equally reflected in corresponding blood samples („liquid biopsy“). Established HFpEF markers poorly correlate with circulating methylated RASAL1, B9D1 and ATP2A2. Established HFpEF markers BNP/NT-proBNP insufficiently identify patients at risk for HFpEF death. Circulating methylated RASAL1, B9D1 and ATP2A2 most effectively identify patients at risk for HFpEF progression.
