摘要
目的评价慢性心力衰竭(心衰)和心衰合并下呼吸道感染患者的血栓风险。方法入选51例慢性心衰患者(CHF组)、26例慢性心衰合并下呼吸道感染患者(CHF+RTI组)、32例健康对照者(对照组),ELISA法检测血浆凝血酶-抗凝血酶Ⅲ复合物(TAT)、凝血酶原片段1+2(F1+ 2)、D-二聚体(D-D)、纤溶酶-抗纤溶酶复合物(PAP)、β-血小板球蛋白(β-TG)和血小板因子4(PF4)。结果3组的6种血栓标志物存在差异,CHF组的各项指标均高于对照组,TAT、F1+2、D-D、PAP、β-TG、PF4分别为(6.29±2.02)与(3.59±1.74)μg/L、(1.43±0.56)与(0.86±0.29)nmol/L、(1.57±0.66)与(0.46±0.28)mg/L、(397.0±117.7)与(238.1±58.1)、(30.84±11.37)与(23.10±7.72)μg/L、(10.28±4.03)与(7.40±3.07)μg/L,差异有统计学意义(均为P<0.01)。CHF组除PAP与CHF+RTI组[分别为(397.0±117.7)与(408.8±87.7)μg/L]比较差异无统计学意义(P >0.05)外,其余5项指标均显著低于CHF-RTI组[TAT:(6.29±2.02)与(8.14±2.51)μg/L,P< 0.01;F1+2:(1.43±0.56)与(1.83±0.52)nmol/L,P<0.01;D-D:(1.57±0.66)与(1.90±0.56)mg/L,P<0.01;β-TG:(30.84±11.37)与(41.92±12.91)μg/L,P<0.01;PF4:(10.28±4.03)与(14.51±4.39)μg/L,P<0.01]。各组内β-TG与PF4呈正相关(r分别为0.605、0.926、0.916,均为P<0.01)。结论慢性心衰患者存在血栓前状态,若合并急性下呼吸道感染,则进一步增加血栓形成的危险性。
