BACKGROUND:Several studies have shown that N-terminal pro-B-type natriuretic peptide (NT-proBNP) is strongly correlated with the complexity of coronary artery disease and the prognosis of patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS), However, it remains unclear about the prognostic value of NT-proBNP in patients with NSTE-ACS and multivessel coronary artery disease (MCAD) undergoing percutaneous coronary intervention (PCI). Therefore, this study aimed to reveal the relationship between NT-proBNP levels and the prognosis for NSTE-ACS patients with MCAD undergoing successful PCI.METHODS:This study enrolled 1022 consecutive NSTE-ACS patients with MCAD from January 2010 to December 2014. The information of NT-proBNP levels was available from these patients. The primary outcome was in-hospital all-cause death. In addition, the 3-year follow-up all-cause death was also ascertained.RESULTS:A total of 12 (1.2%) deaths were reported during hospitalization. The 4th quartile group of NT-proBNP (> 1287 pg/ml) showed the highest in-hospital all-cause death rate (4.3%) (P < 0.001). Besides, logistic analyses revealed that the increasing NT-proBNP level was robustly associated with an increased risk of in-hospital all-cause death (adjusted odds ratio (OR): 2.86, 95% confidence interval (CI) = 1.16-7.03, P = 0.022). NT-proBNP was able to predict the in-hospital all-cause death (area under the curve (AUC) = 0.888, 95% CI = 0.834-0.941, P < 0.001; cutoff: 1568 pg/ml). Moreover, as revealed by cumulative event analyses, a higher NT-proBNP level was significantly related to a higher long-term all-cause death rate compared with a lower NT-proBNP level (P < 0.0001).CONCLUSIONS:The increasing NT-proBNP level is significantly associated with the increased risks of in-hospital and long-term all-cause deaths among NSTE-ACS patients with MCAD undergoing PCI. Typically, NT-proBN P > 1568 pg/ml is related to the all-cause and in-hospital deaths.

Our previous study showed that parenteral anticoagulation therapy (PACT) in the context of aggressive antiplatelet therapy failed to improve clinical outcomes in patients undergoing percutaneous coronary intervention for non-ST-segment elevation acute coronary syndrome (NSTE-ACS). However, the role of PACT in patients managed medically remains unknown. This observational cohort study enrolled patients with NSTE-ACS receiving medical therapy from November 2014 to June 2017 in the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome project. Eligible patients were included in the PACT group and non-PACT group. The primary outcomes were in-hospital all-cause mortality and major bleeding. The secondary outcome included minor bleeding. Among 23,726 patients, 8,845 eligible patients who received medical therapy were enrolled. After adjusting the potential confounders, PACT was not associated with a lower risk of in-hospital all-cause mortality (adjusted odds ratio (OR), 1.25; 95% confidence interval (CI), 0.92-1.71; P = 0.151). Additionally, PACT did not increase the incidence of major bleeding or minor bleeding (major bleeding: adjusted OR, 1.04; 95% CI, 0.80-1.35; P = 0.763; minor bleeding: adjusted OR, 1.27; 95% CI, 0.91-1.75; P = 0.156). The propensity score analysis confirmed the primary analyses. In patients with NSTE-ACS receiving antiplatelet therapy, PACT was not associated with a lower risk of in-hospital all-cause mortality or a higher bleeding risk in patients with NSTE-ACS receiving non-invasive therapies and concurrent antiplatelet strategies. Randomized clinical trials are warranted to reevaluate the safety and efficacy of PACT in all patients with NSTE-ACS who receive noninvasive therapies and current antithrombotic strategies.

BACKGROUND:The model for end-stage liver disease excluding international normalized ratio (MELD-XI) is a simple score for risk assessment. However, the prognostic role of MELD-XI and its additional value to current risk assessment in elderly patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) is uncertain.METHODS:In all, 1029 elderly patients with STEMI undergoing PCI were consecutively included and classified into three groups according to the TIMI risk score: low-risk (≤ 3, n = 251); moderate-risk (4-6, n = 509); and high-risk (≥ 7, n = 269) groups. Multivariate analysis was performed to identify risk factors for adverse events.RESULTS:The overall in-hospital mortality was 5.3% and was significantly higher in the high-risk group (1.2% vs. 3.3% vs. 13.0%, p < 0.001). The optimal cut-off of the TIMI risk score and MELD-XI for in-hospital death was 7 and 13, respectively. MELD-XI was associated with in-hospital (adjusted odds ratio = 1.09, 95% CI = 1.04-1.14, p = 0.001) and one-year (adjusted hazard ratio = 1.05, 95% CI = 1.01-1.08, p = 0.005) mortality independently of the TIMI risk score. Combining TIMI risk score and MELD-XI exhibited better predictive power for in-hospital death than TIMI risk score (area under the curve [AUC] = 0.810 vs. 0.753, p = 0.008) or MELD-XI alone (AUC = 0.810 vs. 0.750, p = 0.018). Patients with TIMI risk score ≥ 7 and MELD-XI ≥ 13 had the worst prognosis.CONCLUSION:MELD-XI could be considered as a risk-stratified tool for elderly patients with STEMI undergoing PCI. It had an additive prognostic value to TIMI risk score.
