CRP and anterolateral myocardial infarction: LASSO regression results show that the λ value when the error is the smallest is 0.006, and there are seven variables corresponding to the non-zero regression coefficient, namely, hypertension, anterior wall myocardial infarction, proximal occlusive disease, CRP > 3.85 mg/L, neutrophil count, lymphocyte count, and NLR > 2.17 (Fig. 3).
