Univariate analysis in the training set showed that age, hypertension, CRP, IL-6, TNF-α, serum albumin, prealbumin, Lp(a), and Hcy were significantly associated with myocardial injury (p < 0.05), while other indicators showed no significant differences (all p > 0.05) (Table 2). The gene discussed is CRP; the disease is hypertensive disorder.
