Abstract:
Objective To investigate the significance of B-type natriuretic peptide (BNP) in acute coronary syndrome(ACS).Methods 151 in-patients of ACS during May 2006 to June 2008 were selected as the treatment group.Other 212 impatients with essential hypertension were selected as control group.Blood lipid,blood glucose,blood routine,renal function,high sensitive C-reaction protein (hs-CRP) and BNP were examined in all patients.Their blood pressure,heart rate,and history of smoking,hypertension,diabetes mellitus and hyperlipidemia 62.0±14.2,t = 5.043,P＜0.001 ),blood creatinine [ (95.0±67.4 ) vs.(72.8±29.0) μmol/L,t = 4.164,P ＜0.001 ),blood uric acid[ (360.2±104.4 ) vs.(300.8±92.7 ) μmol/L,t = 5.521,P ＜ 0.001 ],BNP (80.81 vs.352.38 ng/L,Z = - 7.295,P ＜ 0.001 ),hs-CRP (7.99 vs.17.08,Z = - 3.983,P ＜ 0.001 ),white blood cells (WBC) [ (7.843 +3.025)×109/L vs.(6.333±3.569)×109/L,t =4.209,P ＜0.001 ],monocytes [ (0.522±0.201)×109/L vs.(0.417±0.157)×109/L,t = 5.084,P ＜0.001 ] and blood glucose [ (6.518±2.303 ) vs.(5.691±2.085 ) mmol/L,t = 3.461,P = 0.001 ] had significant difference.Systolic blood pressure had difference between two groups [ (134.7±27.8 ) vs.(142.0±26.3 ) mm Hg,t = 2.536,P=0.012 ].However,the percentage of smoking[ 43.7% (66/151)vs.23.1% (49/212),X2 = 17.283,P ＜0.001 ] and male gender[ 74.8% ( 113/151 )vs.48.6% ( 103/212),X2 = 25.217,P ＜ 0.001 ) ] had significant difference between two groups ( P ＜0.001 ).Multivariable regression analysis showed that age (X2 = 10.369,P =0.001 ),gender (X2 = 12.836,P ＜ O.001 ),BNP (X2 =4.807,P =0.028) and WBC(X2= 10.788,P =0.001 ) were the main factors of difference between the two groups.Moreover,BNP was linearly correlated with left ventricular ejection fraction(EF) in ACS patients (t =5.789,P ＜ 0.001 ).Conclusion Old age,male,WBC and BNP are closely related with ACS,of which BNP has certain predictive value for ACS.
