目的:探讨左房容积指数(LAVI)和血清N端B型利钠多肽(Nt-proBNP)与高血压并发阵发性心房颤动患者的相关性。方法:选择高血压患者68例,根据是否并发心房颤动分为A、B组:A组35例,B组33例,检查2组患者的超声心动图、Nt-proBNP水平并进行比较,并行相关性、敏感度和特异度分析。结果:A组与B组比较,LAVI、Nt-proBNP水平差异有统计学意义(P<0.05);A组的LAVI与NT-proBNP水平呈正相关(P<0.05);LAVI>29 ml/m2+NT-proBNP>143.5μg/L的敏感性、特异性的阳性值最高。结论:LAVI与NT-proBNP联合评价对高血压并发阵发性心房颤动有预测价值。
Objective: To investigate the correlation between left atrium volume index (LAVI) and serum N-terminal pro-N-terminal peptide (Nt-proBNP) in patients with hypertension and paroxysmal atrial fibrillation. Methods: Sixty-eight patients with hypertension were divided into group A and group B according to whether they were complicated with atrial fibrillation: 35 cases in group A and 33 cases in group B. The echocardiography and Nt-proBNP levels in two groups were compared and correlated Sex, sensitivity and specificity analysis. Results: The levels of LAVI and Nt-proBNP in group A were significantly different from those in group B (P <0.05); LAVI was positively correlated with NT-proBNP in group A (P <0.05); LAVI was higher than 29 ml / m2 + NT-proBNP> 143.5μg / L of sensitivity, the highest specificity of the highest value. Conclusion: The combined assessment of LAVI and NT-proBNP has predictive value for the occurrence of paroxysmal atrial fibrillation in patients with hypertension.
