| Summary: | Introduction : The aim was to evaluate the association of serum total cholesterol (TC) level and left ventricular ejection fraction (LVEF) in patients with heart failure (HF) caused by coronary heart disease (CHD).
Material and methods : A total of 236 participants were enrolled. Participants were divided into severely reduced (≤ 35%) and moderately reduced (> 35%) LVEF groups and the between-group difference was evaluated. Multivariate regression analysis was used to evaluate the association between LVEF and parameters of interest. Linear regression analysis was applied to analyze the odds ratio of per 1-SD increase in serum TC level for LVEF change.
Results : Mean age was 57.3 years and males accounted for 58.1%. Mean serum TC level was 4.6 mmol/l, albumin (ALB) 33.6 g/l, and C-reactive protein (CRP) 11.4 mg/l. Mean LVEF was 38.3%. Compared to high-reduced LVEF group, participants in moderate-reduced LVEF group had significantly higher TC (4.8 ±0.9 mmol/l vs. 4.4 ± 0.7 mmol/l) and ALB (35.8 ±6.7 g/l vs. 31.4 ±6.0 g/l) but lower CRP (9.6 ±4.7 mg/l vs. 14.2 ±7.0 mg/l) levels (p < 0.05 for all comparisons). Increased TC and ALB levels were associated with higher LVEF, and increased CRP level was associated with lower LVEF. After adjusted for CRP, although per 1-SD increase in TC level was still associated with an increment in 4 % in LVEF, it did not achieve achieve statistic significance.
Conclusions : In patients with HF caused by CHD, higher serum TC level appeared to be associated with higher LVEF, which might be associated with systemic inflammation improvement. |
