DNMT3A and coronary artery disorder: As expected, patients with LOY ≥17% were significantly older, but also had significantly higher NT‐proBNP serum levels and higher values of LVEF as well as lower haemoglobin levels and a slightly reduced incidence of coronary artery disease, while the prevalence of DNMT3A/TET2 CHIP‐driver mutations was not significantly increased.
