Our study showed that the variables such as age ≥70 years, heart rate >100 bpm, BMI, SBP ≥160 mmHg, history of aortic surgery, pleural effusion, pericardial effusion, ischemic cerebrovascular disease, PVD, coma, anemia, eGFR <60 ml/min, and abnormal cTnT levels, were therefore included in the multivariate logistic regression analysis because they were significantly different in the univariate logistic regression analysis (P < 0.05). The gene discussed is TNNT2; the disease is anemia (phenotype).
