Considering the hazard ratio (HR), we finally included age (HR 1.04, 95% CI 1.02–1.07, p = 0.002), HER2 (HR 0.22, 95% CI 0.10–0.48, p < 0.001), TG (HR 0.59, 95% CI 0.41–0.86, p = 0.006) and ApoB (HR 4.58, 95% CI 1.17–17.93, p = 0.029) in the following analysis for myocardial ischemia in breast cancer patients (Table 3 and Figure 2A). This evidence concerns the gene APOB and breast carcinoma.
