Abstract:
Objective:To investigate the correlation between serum melatonin level and cardiac function, blood lipid in patients of heart failure with preserved ejection fraction (HFpEF).
Methods:One hundred and seventy patients with HFpEF (HFpEF group) in Ninth Hospital of Xi′an City from May 2016 to May 2018 were selected. According to the cardiac function grading of New York Heart Association (NYHA), Ⅱ grade (cardiac function Ⅱ grade) was in 98 cases, and Ⅲ grade (cardiac function Ⅲ grade) was in 72 cases. Then, 32 healthy volunteers were selected as control group. The 2 groups were sampled at 2:00 and 7:00, and the level of melatonin was detected by enzyme-linked immunosorbent assay. The correlation between serum melatonin level and cardiac function, blood lipid were analyzed (Pearson correlation), including triglyeride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), N-terminal precursor brain natriuretic peptide (NTproBNP), hypersensitive C reactive protein (hs-CRP), ejection fraction, left ventricular end-diastolic volume index (LVEDVI), miral diastolic early and end-diastolic maximum blood flow velocity ratio (E/A) and peak value of early diastolic blood flow velocity in the mitral valve and peak value of the early diastolic velocity of the mitral annulus (E/e′).
Results:The TG, TC, LDL-C, NTproBNP and hs-CRP in cardiac function Ⅲ grade patients were significantly higher than those in cardiac function Ⅱ grade patients: (1.51 ± 0.69) mmol/L vs. (1.15 ± 0.75) mmol/L, (4.03 ± 1.02) mmol/L vs. (3.47 ± 0.94) mmol/L, (1.42 ± 0.33) mmol/L vs. (1.17 ± 0.31) mmol/L, (3 438.54 ± 553.58) ng/L vs. (3 034.58 ± 557.35) ng/L and (4.26 ± 2.54) mg/L vs. (3.12 ± 2.13) mg/L, the HDL-C, ejection fraction and E/A were significantly lower than those in cardiac function Ⅱ grade patients: (2.44 ± 0.88) mmol/L vs. (2.97 ± 0.94) mmol/L, (56.23 ± 5.26)% vs. (61.11 ± 5.33)% and 0.82 ± 0.18 vs. 0.91 ± 0.17, and there were statistical differences (P<0.01). The melatonin levels at 2:00 and 7:00 in control group and cardiac function Ⅱgrade patients of HFpEF group were significantly higher than those in cardiac function Ⅲ grade patients of HFpEF group: (454.24 ± 123.54) and (432.68 ± 155.68) ng/L vs. (368.85 ± 98.52) ng/L, (483.25 ± 90.54) and (418.54 ± 103.57) ng/L vs. (345.85 ± 98.52) ng/L, the melatonin level at 7:00 in control group was significantly higher than that in cardiac function Ⅱ grade patients of HFpEF group, and there was statistical difference (P<0.01). In cardiac function Ⅱ grade patients of HFpEF group, the melatonin level was correlated with TG, TC, LDL-C and HDL-C (P<0.01); In cardiac function Ⅲ grade patients of HFpEF group, the melatonin level was correlated with NTproBNP, hs-CRP, ejection fraction, LVEDVI, E/A, E/e′, TG, TC, LDL-C and HDL-C (P<0.01 or <0.05).
Conclusions:The melatonin level is correlated with the level of blood lipid in HFpEF patients. Melatonin level is correlated with cardiac function Ⅲ grade patients, but this phenomenon is not observed in cardiac function Ⅱ grade patients.
