ABSTRACT: Background
High-density lipoprotein (HDL) has cardioprotective properties. Each HDL particle has a few molecules of apolipoprotein A-I (apoA-I) and carries various amounts of cholesterol. The ratio of high-density lipoprotein cholesterol (HDL-C) to apoA-I may reflect mean HDL particle size.Hypothesis
HDL-C/apoA-I ratio may provide more information than HDL-C and apoA-I in predicting myocardial injury following elective percutaneous coronary intervention (PCI).Methods
We prospectively enrolled 2529 consecutive patients who underwent elective PCI and assessed the relationships of preprocedural HDL-C, apoA-I, and their ratio with peak cardiac troponin I (cTnI) within 24 hours after PCI.Results
Neither HDL-C nor apoA-I levels showed significant association with postprocedural cTnI elevation, whereas HDL-C/apoA-I ratio was associated with postprocedural cTnI elevation above 3 up to 30 × upper limit of normal (ULN), with the lowest risk in the middle quintile (all P values for quadratic term were <0.05). Adjusted odds ratios (95% confidence interval) of postprocedural cTnI >3 × ULN for quintile 1 to 5 of HDL-C/apoA-I ratio were: 1 (reference), 0.81 (0.62-1.07), 0.57 (0.43-0.75), 0.65 (0.49-0.85), and 0.76 (0.58-1.01), respectively, and the adjusted odds ratios of postprocedural cTnI >30 × ULN for quintile 1 to 5 of HDL-C/apoA-I ratio were: 1 (reference), 0.81 (0.49-1.361), 0.42 (0.23-0.77), 0.66 (0.38-1.14), and 0.82 (0.49-1.38), respectively.Conclusions
There was a U-shaped association between HDL-C/apoA-I ratio and myocardial injury following PCI.
