Abstract:
Objective:To investigate the relationship between serum lipid levels and the risk of pulmonary embolism in patients with non-valvular atrial fibrillation.Methods:Patients with non-valvular atrial fibrillation admitted to Tianjin Chest Hospital from January 2014 to January 2019 were retrospectively analyzed.According to whether pulmonary embolism was present on CT pulmonary angiography, patients were divided into two groups, the atrial fibrillation with pulmonary embolism group(the AP group)and the control group(the AF group). Clinical data and serum lipid test results were compared between the two groups.The relationship between serum lipid levels and the risk of pulmonary embolism was evaluated.Results:Levels of apolipoprotein A1(ApoA1)and high-density lipoprotein cholesterol(HDL-C)in the AP group were(1.09±0.25)g/L and(1.03±0.28)mmol/L, which were lower than those in the AF group(1.24±0.25)g/L and(1.21±0.37)mmol/L)( t=3.255, P=0.002; t=2.972, P=0.004, respectively). Levels of very low-density lipoprotein cholesterol(VLDL-C)in the AP group were(0.41±0.24)mmol/L, which were higher than those in the AF group(0.26±0.18)mmol/L)( t=-3.761, P=0.000). The grade of cardiac function on admission in the AP group was higher than that in the AF group( χ2=13.074, P=0.004). The proportion of patients treated for atrial fibrillation in the AP group was lower than that in the AF group( χ2=5.445, P=0.020). Logistic regression analysis showed that decreased ApoA1 and left cardiac insufficiency were risk factors for pulmonary embolism in patients with non-valvular atrial fibrillation( OR=8.793, 95% CI: 1.815~42.607, P=0.007; OR=4.388, 95% CI: 1.352~14.244, P=0.014, respectively). Decreased VLDL-C and atrial fibrillation therapy were protective factors for pulmonary embolism( OR=0.180, 95% CI: 0.053~0.610, P=0.006; OR=0.268, 95% CI: 0.072~0.992, P=0.049, respectively). Conclusions:Pulmonary embolism in patients with non-valvular atrial fibrillation is related to serum lipid levels.Regulating levels of serum lipids may reduce the risk of pulmonary embolism in patients with non-valvular atrial fibrillation.
