Shock Timing in STEMI-CS

  • retrospective cohort analysis
  • multicenter registry (RECUIMA)
  • 4 Cuban hospitals

Authors' conclusion

PRC patients presented with greater severity, received less inpatient best available medical therapy, and had higher unadjusted mortality. However, in the multivariable logistic regression model, shock timing was not statistically significantly associated with mortality.

Study context

Population
Patients with cardiogenic shock complicating STEMI, from a registry of patients with STEMI admitted to 4 Cuban hospitalsdeveloped cardiogenic shock, among 4,113 patients with STEMI · PRC 134 · a reperfusion center (ARC) 301
Participants
435 patients
Exposure
shock onset before vs after arrival at a reperfusion center
  • PRCn = 134
  • ARCn = 301reference

Main finding

As reported in the abstract

Clinical severity (systolic blood pressure, left ventricular ejection fraction, renal function, Global Registry of Acute Coronary Events scores)

PRC patients had greater clinical severity, including lower systolic blood pressure and left ventricular ejection fraction, worse renal function, and higher Global Registry of Acute Coronary Events scores

all P < 0.01

Observational data: associations, not effects.
