Chen BD, Chen XC, Yang YN, et al. - In patients with non-ST segment elevation myocardial infarction (NSTEMI) [one of the most severe and lethal form of myocardial infarction], researchers investigated lipid profile and SYNTAX score. Participants in the study were 311 patients with NSTEMI. To detect confounding factors linearly correlated with SYNTAX score, the Pearson linear correlation was used. The Pearson linear correlation demonstrated that high-density lipoprotein- cholesterol and apolipoprotein A1 (ApoA1) were significantly associated with Syntax Score. According to findings, ApoA1 is the only lipid factor significantly associated with coronary artery lesion complexity in NSTEMI patients; patients with ApoA1 < 1.07 g/L may experience more complex coronary artery lesions.
