ABSTRACT
<p><b>OBJECTIVE</b>To investigate the prognostic value of ultra-sensitive pregnancy associated plasma protein-A (PAPP-A) level in the early phase of acute coronary syndrome (ACS) attack.</p><p><b>METHODS</b>Patients diagnosed as ACS were enrolled and the level of circulatory PAPP-A was measured within 12 hours after ACS attack. The patients were followed at the time of 1st, 6th, and 12th months post-ACS attack in order to observe the incidence of the cardiovascular adverse events. According to the highest quintile, the patients were divided into 2 groups: high level (≥26.08 μg/L) group and low level (<26.08 μg/L) group, to evaluate the association between the level of PAPP-A and the incidence of the cardiovascular events.</p><p><b>RESULTS</b>Compared with the low level group, the incidence of the composite outcome is significantly increased in the high level group, and the values of OR are 4.76, 4.38, 3.75 for 1st, 6th, 12th months respectively (P=0.000). For myocardial infarction (MI) + cardiac death (CD) the values of OR were 9.81, 6.08, 4.12 (P<0.01). Multivariate logistic regression analysis demonstrates that PAPP-A was an independent risk factor for the cardiovascular adverse events in the early, median, and late phase of ACS (P<0.05).</p><p><b>CONCLUSION</b>In the early phase of ACS attack, the elevation of PAPP-A is an independent risk factor for the occurrence of cardiovascular adverse events.</p>

Objective To explore the long-term predictive value of serum concentration of N-terminal prosoma brain natriuretic peptide (NT-proBNP) in the early acute coronary syndrome (ACS). Methods The 164 patients firstly hospitalized and finally diagnosed as acute myocardial infarction (AMI) were selected, and then the serum concentration of NT-proBNP was determined in less than 12 hours. According to the 75 percentage points of serum concentration of NT-proBNP, the patients were divided into two groups: low concentration group (n = 123) and high concentration group (n = 41 ). The major adverse cardiac events (MACEs) were followed and compared at one month, six months and twelve months between low group and high group. Results At 1-, 6-, 12-month follow-up, the odds ratio (OR) of death event were 4.1, 5.6 and 4.0 in high group respectively, and the nonfatal heart failure occurred in 4, 4 and 7 patients in high group. Multiple factor logistic regression analysis showed that NT-proBNP was an independent risk factor of the MACEs at different periods including short time, middle time and long time in ACS patients (P＜0. 05). Conclusions NT-proBNP is a strong predictor of the long-term MACEs in patients with early ACS.
