摘要: 目的探讨急性冠脉综合征(ACS)患者并发1型心肾综合征(CRS)的高危因素,分析其对主要心脏不良事件(MACE)发生率的影响。方法连续入选2015年1-4月于河北医科大学第二医院心血管内科住院的ACS病例,观察ACS患者1型CRS 的发生率和住院期间MACE 发生情况,分析ACS 并发1型CRS患者的人口学特征和临床特点,判断ACS并发1型CRS的高危因素。结果累计入选ACS患者109例,平均年龄(59.3±9.0)岁,男84例,并发1型CRS(CRS组)11例,发生率10.1%。未并发CRS者98例为对照组。与对照组比较,CRS组急性ST段抬高性心肌梗死(STEMI)的比例较高(72.7% vs  23.5%,P=0.002),且入院时GRACE和CRUSADE评分均较高(均P<0.01)。CRS组入院前发生猝死的比例较高(36.4%  vs  2.0%,P<0.01),与对照组相比,CRS组入院时血细胞比容较低(P=0.049)。CRS组住院期间肌酸激酶(CK)峰值水平和肌钙蛋白I(cTnI)峰值水平明显高于对照组。CRS组左心室射血分数(LVEF)和舒张早期二尖瓣血流速度与舒张早期二尖瓣环运动速度的比值(E/e’)低于对照组。CRS组多支血管病变比例较高,两组经皮冠状动脉介入(PCI)治疗的比例、平均支架置入数和平均支架长度差异无统计学意义。住院期间,CRS组MACE发生率明显高于对照组(45.5%  vs  16.3%,P=0.020),CRS组心力衰竭比例明显高于对照组(18.2%  vs  0%,P=0.009)。多因素Logistic回归分析结果显示,入院时血肌酐(SCr)水平和cTnI峰值是ACS患者住院期间发生1型CRS的独立危险因素(均P<0.05)。结论ACS合并1型CRS患者预后不佳,cTnI峰值较高和入院时SCr水平升高是ACS患者并发1型CRS的高危因素。

Abstract: ObjectiveTo analyze the incidence and risk factors of  type 1  cardiorenal  syndrome (CRS) in patients with acute coronary syndrome (ACS).MethodsConsecutive patients with ACS who were admitted to our department were enrolled in this study from January 2015 to April 2015. All the eligible cases were divided to CRS group and control group according to the incidence of type 1 CRS. The baseline clinical characteristics and the procedure of coronary interventions were recorded and compared. The incidence of major adverse events (MACE) were followed up. Logistic regression analysis was used for the predictor of type 1 CRS in ACS patients.ResultsA total of 109 patients with ACS were enrolled,the average age was 59.3±9.0 years old, and 84 cases were male. The incidence of type 1 CRS was 10.1%. STEMI patients were more common (72.7% vs 23.5%,P=0.002), GRACE and CRUSADE scores were higher in  CRS group compared with those of control group (both P<0.01). The incidence of sudden death before admission was higher (36.4% vs 2.0%,P<0.01)  and HCT was lower (P=0.049)  in CRS group compared to the control group. The peak levels of CK and cTnI were higher in CRS group than those in the control group, while LVEF and E/e’ were lower. No significance of interventional characteristics were found except ratio of multivessel diseases. During the hospitalization, the incidences of MACE (45.5% vs 16.3%,P=0.020) and heart failure were higher in CRS group than those in the control group (18.2% vs 0%,P=0.009). Logistic regression analysis showed that the baseline level of serum creatinin(SCr) and peak value of cTnI were independent risks of type 1 CRS in patients with ACS during the hospitalization (both P<0.05).ConclusionACS combined with type 1 CRS patients in poor prognosis, high cTnI peak and increased SCr level at admission were risks for type 1 ACS in patients with CRS.
