Univariable Cox regression showed patients ≥ 60 years old (HR: 1.6, 95% CI: 1.3−2, p < 0.001), females (HR: 2, 95% CI: 1.6−2.4, p < 0.001), CCF (HR: 1.8, 95% CI: 1.3−2.5, p < 0.001), and IHD (HR: 1.8, 95% CI: 1.3−2.7, p = 0.001) were associated with increased probability of 6‐month readmission, while multivariate analysis showed that patients ≥ 60 years (HR: 1.7, 95% CI: 1.4−2.2, p < 0.001), females (HR: 2.2, 95% CI: 1.7−2.8, p < 0.001), and CCF (HR: 2.1, 95% CI: 1.6−2.7, p < 0.001) were independently associated with increased risk of 6‐month readmission (Table 2). Here, PITX1 is linked to myocardial ischemia.
