Abstract:
Objective To investigate the correlation of plasma N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) level with echocardiographic indicators and P wave terminal force of lead V 1 (PtfV1) in the patients with hypertension and paroxysmal atrial fibrillation(PAF) .Methods Fifty‐six outpatients and inpatients with hypertension were divided into the PAF group (n=26) and the sinusrhythm group (n=30) .Thirty age‐matched and gender‐matched healthy volunteers were taken as the control group . The plasma NT‐proBNP level was determined .Left ventricular enddiastolic diameter (LVEDD) ,left atrial diameter(LAD) and left ventricular ejection fraction(LVEF) were examined by echocardiography .the 12‐lead electrocardiogram was routinely performed Pt‐fV1 was calculated .Results The plasma NT‐proBNP level in the PAF group was higher than that in the sinusrhythm group and the control group ,the difference was statistically significant (P<0 .05) .The plasma NT‐proBNP level in the PAF group was de‐creased significantly after successful cardioversion .The plasma NT‐proBNP level in the PAF group was positively correlated with LVEDD(r=0 .543 ,P<0 .05) and LAD (r=0 .606 ,P<0 .01) .The plasma NT‐proBNP level was negatively correlated with LVEF (r= -0 .750 ,P<0 .01) and positively correlated with the PtfV 1 absolute value (r= 0 .513 ,P< 0 .01) .Conclusion The plasma NT‐proBNP level can better reflect the heart structure and function in the patients with atrial fibrillation .Detecting the plasma NT‐proBNP level combined with echocardiographic indicators and PtfV 1 is conducive to comprehensively assess the heart function in the patients with hypertension and PAF .
