D-dimer has predictive value for mortality in some diseases. This study aimed to evaluate the correlation between D-dimer and mortality in patients undergoing percutaneous coronary intervention (PCI).
We examined 10,724 consecutive patients who underwent PCI between January 2013 and December 2013. The primary endpoint was all-cause mortality, and the secondary endpoint was cardiac mortality. Patients were divided according to the median D-dimer level of 0.28 μg/ml. Multivariable model were including age, sex, and risk factors after stepwise selection.
After a 2-year follow up, 8565 patients with D-dimer data were analyzed. There were 116 (1.35%) all-cause deaths and 64 (0.75%) cardiac deaths. D-dimer levels were significantly higher in the all-cause mortality group [0.42 (0.29, 0.68) μg/ml] and cardiac mortality group [0.48 (0.30, 0.81) μg/ml] than in the survival group [0.28 (0.20, 0.41) μg/ml] (both < 0.001). Multivariate-adjusted Cox hazard analysis showed that high D-dimer levels (⩾0.28 μg/ml) were significantly associated with all-cause mortality in the total population [hazard ratio (HR): 2.35, 95% confidence interval (CI): 1.44-3.84, = 0.001], acute coronary syndrome (ACS) subgroup (HR: 1.91, 95% CI: 1.08-3.38, = 0.027), and stable coronary artery disease (SCAD) subgroup (HR: 3.82, 95% CI: 1.45-10.10, = 0.007). High D-dimer levels were significantly associated with cardiac mortality in the total population (HR: 3.44, 95% CI: 1.61-7.36, = 0.001) and the ACS subgroup (HR: 3.33, 95% CI: 1.38-8.03, = 0.007), but not in the SCAD subgroup (HR: 3.68, 95% CI: 0.80-16.91, = 0.094).
D-dimer levels are independently associated with 2-year all-cause mortality and cardiac mortality in patients undergoing PCI.
D - 二聚体在某些疾病中对死亡率具有预测价值。本研究旨在评估接受经皮冠状动脉介入治疗（PCI）患者中D - 二聚体与死亡率之间的相关性。
我们检查了2013年1月至2013年12月期间连续接受PCI的10724例患者。主要终点是全因死亡率，次要终点是心脏死亡率。患者根据D - 二聚体水平中位数0.28μg/ml进行分组。多变量模型在逐步选择后纳入了年龄、性别和危险因素。
经过2年随访，对8565例有D - 二聚体数据的患者进行了分析。有116例（1.35%）全因死亡和64例（0.75%）心脏死亡。全因死亡率组[0.42（0.29，0.68）μg/ml]和心脏死亡率组[0.48（0.30，0.81）μg/ml]的D - 二聚体水平显著高于存活组[0.28（0.20，0.41）μg/ml]（均P < 0.001）。多变量校正的Cox风险分析显示，高D - 二聚体水平（≥0.28μg/ml）与总人群的全因死亡率显著相关[风险比（HR）：2.35，95%置信区间（CI）：1.44 - 3.84，P = 0.001]，急性冠状动脉综合征（ACS）亚组（HR：1.91，95%CI：1.08 - 3.38，P = 0.027）和稳定冠状动脉疾病（SCAD）亚组（HR：3.82，95%CI：1.45 - 10.10，P = 0.007）。高D - 二聚体水平与总人群（HR：3.44，95%CI：1.61 - 7.36，P = 0.001）和ACS亚组（HR：3.33，95%CI：1.38 - 8.03，P = 0.007）的心脏死亡率显著相关，但在SCAD亚组中无显著相关性（HR：3.68，95%CI：0.80 - 16.91，P = 0.094）。
D - 二聚体水平与接受PCI患者的2年全因死亡率和心脏死亡率独立相关。
