Design and preliminary results of FRENSHOCK 2016: A prospective nationwide multicentre registry on cardiogenic shock.

BACKGROUND

Most data on the epidemiology of cardiogenic shock (CS) have come from patients with acute myocardial infarction admitted to intensive cardiac care units (ICCUs). However, CS can have other aetiologies, and could be managed in intensive care units (ICUs), especially the most severe forms of CS.

AIM: To gather data on the characteristics, management and outcomes of patients hospitalized in ICCUs and ICUs for CS, whatever the aetiology, in France in 2016.

METHODS

We included all adult patients with CS between April and October 2016 in metropolitan France. CS was defined (at admission or during hospitalization) by: low cardiac output, defined by systolic blood pressure<90mmHg and/or the need for amines to maintain systolic blood pressure>90mmHg and/or cardiac index<2.2L/min/m2; elevation of the left and/or right heart pressures, defined by clinical, radiological, biological, echocardiographic or invasive haemodynamic overload signs; and clinical and/or biological signs of malperfusion (lactate>2mmol/L, hepatic insufficiency, renal failure).

RESULTS

Over a 6-month period, 772 patients were included in the survey (mean age 65.7±14.9 years; 71.5% men) from 49 participating centres (91.8% were public, and 77.8% of these were university hospitals). Ischaemic trigger was the most common cause (36.3%).

CONCLUSIONS

To date, FRENSHOCK is the largest CS survey; it will provide a detailed and comprehensive global description of the spectrum and management of patients with CS in a high-income country.
