Abstract
En 中文
Background: Cardiogenic shock (CS) continues to be a severe and fatal complication of acute coronary syndrome (ACS). CS patients have a high mortality rate despite significant progress in primary reperfusion, the management of heart failure and the expansion of mechanical circulatory support strategies. The present study addressed the clinical characteristics, management, and outcomes of ACS patients complicated with CS. Methods: We performed an observational study, using the 2000-2013 Acute Coronary Syndrome Israeli Surveys (ACSIS) database and identified hospitalizations of ACS patients complicated with CS. Patients' demographics and clinical characteristics, complications and outcomes were evaluated. We assessed the outcomes of ACS patients with CS at arrival (on the day of admission) compared with ACS patients who arrived without CS and developed CS during hospitalization. Results: The cohort included 13,434 patients with ACS diagnoses during the study period. Of these, 4.2% were complicated with CS; 224 patients were admitted with both ACS and CS; while 341 ACS patients developed CS only during the hospitalization period. The latter patients had significantly higher rates of MACEs compared with the group of ACS patients who presented with CS at arrival (73% vs. 51%; p < 0.0001). Similarly, the rates of in-hospital mortality (55% vs. 36%; p < 0.0001), 30-day mortality (64% vs. 50%; p = 0.0013) and 1-year mortality (73% vs. 59%; p = 0.0016) were higher in ACS patients who developed CS during hospitalization vs. ACS patients with CS at admission. There was a significant decrease in 1-year mortality trends during the 13 years of this study presented in ACS patients from both groups. Conclusions: Patients who developed CS during hospitalization had higher mortality and MACE rates compared with those who presented with CS at arrival. Further studies should focus on this subgroup of high-risk patients.
