Osimertinib therapy was associated with an increased risk of HF (RR = 1.45, 95% CI 1.19-1.76, p = 0.0002), decline in LVEF (RR = 3.10, 95% CI 1.72-5.59, p = 0.0002) and MI (RR = 1.40, 95% CI 1.09-1.79, p = 0.0078) compared to other EGFR inhibitors. This evidence concerns the gene EGFR and hydrops fetalis.
