目的观察阵发性心房颤动患者血浆硫化氢(H2S)水平变化,研究其与阵发性心房颤动的相关性。方法 50例阵发性心房颤动患者作为病例组,50例健康受试者作为对照组,采用去蛋白法测定血清H2S水平。结果病例组血浆H2S水平(28.63±12.74)μmol/L显著低于对照组(49.21±10.95)μmol/L(P<0.01)。结论阵发性心房颤动的发生可能与患者血浆H2S水平的降低有关。
Objective To observe the changes of plasma hydrogen sulfide (H2S) level in patients with paroxysmal atrial fibrillation and to investigate its relationship with paroxysmal atrial fibrillation. Methods Fifty patients with paroxysmal atrial fibrillation were selected as the case group and 50 healthy subjects as the control group. The level of serum H2S was determined by deproteinization. Results The level of plasma H2S in the patients (28.63 ± 12.74) μmol / L was significantly lower than that in the control group (49.21 ± 10.95) μmol / L (P <0.01). Conclusions The occurrence of paroxysmal atrial fibrillation may be related to the decrease of plasma H2S level in patients.
