Abstract:
Objective To investigate the clinical characteristics and angiographic findings of cardiogenic shock(CS)following acute myocardial infarction(AMI) in elderly patients.Methods Between January 2015 and April 2016,we carried out a retrospective observational analysis of consecutive elderly patients in Tianjin Chest Hospital,who suffered CS-complicating AMI.Emergency angiography and percutaneous coronary intervention(PCI) were performed after admission.All selected patients were divided into CS and non-CS groups according to whether CS occurred.Electrocardiograph (ECG),cardiac enzyme testing,and ultrasound cardiography were performed after admission to monitor the occurrence of CS.Results The incidence of CS-complicating AMI was 8.33％ (34/408) in elderly patients.Among all CS patients enrolled,the aged patients accounted for 91.89 ％ (3 4/3 7).In-hospital mortality rate was 2 9.41 ％ (10/3 4).There were significant differences between two groups in WBC,H s-CRP,blood glucose,CR and ALT (t =2.403,4.596,6.778,6.109,each P＜0.05).The NT-Pro BNP level,the time of FMC,the frequency of left main and multivessel disease were higher in the CS group than in the non-CS group (each P ＜ 0.05).Conclusions Elderly patients are bearing high risk of CS following AMI.Prolonged FMC time and the presence of left main and/or multivessel lesion are independent risk factors for the development of CS.The optimal revascularisation strategy can improve the clinical outcome of patients with CS.
