Abstract

High low-density lipoprotein-cholesterol to high-density lipoprotein-cholesterol (L/H) ratio is associated with progressions of coronary arteriosclerosis and chronic kidney disease. On the other hand, renal function markedly declined after acute myocardial infarction (AMI). The aims of the present study were (1) to identify what type of patients with AMI would have high L/H ratio at follow-up and (2) to evaluate whether decline in renal function after AMI had accelerated or not in patients with high L/H ratio. The 190 eligible AMI patients who underwent primary percutaneous coronary intervention (PCI) and received atorvastatin (10 mg) were divided into one of two groups according to the L/H ratio at 6-month follow-up: L/H >2 group (n = 81) or L/H ≤2 group (n = 109). The characteristics on admission in the two groups were examined. Furthermore, changes in serum creatinine (sCr) and estimated glomerular filtration rate (eGFR) during 1- and 6-month follow-up were compared between the two groups. L/H >2 group were significantly younger and had greater body mass index (BMI) and worse lipid profile on admission compared with L/H ≤2 group. Percentage increase in sCr and percentage decrease in eGFR during 1-month follow-up in L/H >2 group tended to be greater than in L/H ≤2 group, and those during 6-month follow-up were significantly greater (16.5 ± 2.77 vs. 9.79 ± 2.23%, p = 0.03 and 11.8 ± 1.93 vs. 2.75 ± 3.85%, p = 0.04, respectively). In AMI patients undergoing primary PCI, those who were young and had large BMI and poor lipid profile on admission were likely to have a high L/H ratio at follow-up despite statin therapy. In addition, the decline in renal function after AMI had significantly accelerated in patients with high L/H ratio.
