Polish Nationwide Registry of Diagnostics, Treatment and Outcome in Patients With Cardiogenic Shock

The prospective registry will be open in nature; any cardiology department in Poland with access to a 24-hour hemodynamic laboratory will be eligible to participate in the study. All participants will use an electronic CRF (Case Report Form) to anonymously collect data on the incidence, etiology, diagnosis, treatment approaches, and prognosis of patients with cardiogenic shock. Data will be collected by researchers from the medical documentation of participating centers. The data collection period will span six months, followed by a six-month prospective observation through visit in person, per telephone contact to the patient or his/her relatives or by retracting National Health Fund data in case the contact to the patient or his/her relatives is impossible.

To enable comparison with global data, collected information will include, among other aspects, the latest Society for Cardiovascular Angiography and Interventions (SCAI) classification for cardiogenic shock, the availability and application of modern short- and long-term mechanical circulatory support techniques, and the frequency of heart transplants.

Inclusion criteria

• Cardiogenic shock patients of all etiologies in SCAI stage B, C, D, E.
• age > 18 years old
• persistent hemodynamic failure defined as systolic blood pressure of <90 mmHg for ≥ 30 minutes or the requirement for inotropic or vasopressor agents with evidence of hypoperfusion of the peripheral organs

Exclusion criteria

• patients without return of spontaneous circulation who were considered to extracorporeal cardiopulmonary resuscitation (ECPR)
• primary septic, anaphylactic, hypovolemic shock
• post-operative cardiogenic shock
• end-stage of heart failure disqualified from mechanical circulatory support and heart transplantation
