Low adherence to secondary prevention medications (ATM) of patients after acute coronary syndrome (ACS) is associated with poor clinical outcomes. However, literature provides limited data on assessment of ATM and risks associated with poor in Chinese patients with ACS. In the current work, ATM was assessed in consecutively recruited patients with ACS in Tongji Hospital from November 5, 2013 to December 31, 2014. A total of 2126 patients were classified under low adherence (proportion of days covered (PDC)<50%) and high adherence (PDC>50%) groups based on their performance after discharge. All patients were followed up at the 1st, 6th, and 12th month of discharge while recording ATM and major adverse cardiac events (MACE). Bivariate logistic regression was used to identify the factors associated with ATM. Cox regression was used to analyze the association between ATM and MACE within one year after discharge. Results showed that coronary artery bypass grafting (CABG) alone had significantly lower proportion of high adherence to P2Y12 antagonists (83.0% vs. 90.7%, P<0.01) than patients treated with percutaneous coronary intervention (PCI) only. Moreover, in patients undergoing PCI, high adherence to P2Y12 antagonists decreased the risk of MACE (hazard ratio=0.172, 95% confidence interval: 0.039–0.763; P=0.021). In conclusion, PCI-treated patients are more prone to remaining adherent to medications than CABG-treated patients. High adherence to P2Y12 antagonists was associated with lower risk of MACE.

分析了CAN总线的时间触发机制,基于8052单片机和CAN控制器SJA1000设计了时间触发机制的实现方案,给出了网络中基本周期中可传输的最大消息数目及可调度分析方法。以汽车引擎控制系统为例进行的实验结果表明,利用CAN总线时间触发机制不仅可以有效地管理消息的传输,而且提高了总线带宽利用率。
