PLA2G7 and myocardial infarction: Studies have confirmed that higher level of Lp-PLA2 is an independent predictor of coronary heart disease (Yang et al., 2017), myocardial infarction (Sun et al., 2021), acute cerebral infarction (Tao et al., 2020), and cerebral artery stenosis (Wang et al., 2018), and is also closely related to the patient’s admission severity, later treatment, and prognosis.
